Description

本発明は、乾燥条件に応じて自動追随して乾燥制御を行う乾燥条件自動追随型の乾燥方法および乾燥制御装置に関する。 The present invention relates to a drying condition automatic tracking type drying method and a drying control device that automatically follow drying according to drying conditions and perform drying control.

洗濯物の乾燥処理には、一般に乾燥空気を回転ドラム内に収容された洗濯物に接触させて水分を蒸発させて乾燥させる回転ドラム式乾燥機が使用されている（例えば、特許文献１参照）。 For the drying process of laundry, a rotary drum type dryer is generally used in which dry air is brought into contact with the laundry contained in the rotary drum to evaporate the moisture and dry (see, for example, Patent Document 1). ..

回転ドラム式乾燥機においては、回転ドラム内に洗濯物を投入し、回転ドラムを回転させながら室温よりも高温の乾燥空気を外部より供給し、ドラム側面に形成した通気孔を介して該乾燥空気をドラム内部に導入して乾燥処理が行われる。 In the rotary drum type dryer, laundry is put into the rotary drum, dry air having a temperature higher than room temperature is supplied from the outside while rotating the rotary drum, and the dry air is supplied through a ventilation hole formed on the side surface of the drum. Is introduced into the drum and the drying process is performed.

特開２００７－６１４１１号公報Japanese Unexamined Patent Publication No. 2007-61411

従来の乾燥処理は、回転ドラム内に高温空気を一気に導入しても被乾燥物の内部に水分が残留するので、乾燥開始から終了までの乾燥工程で、所定の乾燥処理時間中に、回転ドラムから排気された排気空気を再び回転ドラムに戻して循環させる循環量の割合、つまり循環率（％）に対する、設定した時間の経過従う監視ポイントを１、２点設定して乾燥空気を供給する段階設定制御方式によって行われていた。 In the conventional drying process, even if high-temperature air is introduced into the rotating drum at once, moisture remains inside the object to be dried. Therefore, in the drying process from the start to the end of drying, the rotating drum can be used during a predetermined drying process time. At the stage of supplying dry air by setting one or two monitoring points according to the passage of the set time with respect to the ratio of the circulation amount that the exhaust air exhausted from is returned to the rotating drum and circulated, that is, the circulation rate (%). It was done by the setting control method.

図１５は、従来の段階設定制御方式による乾燥制御内容を示す。図１５において、横軸は乾燥処理時間（分）を示し、縦軸は循環率（％）を示す。 FIG. 15 shows the content of drying control by the conventional step setting control method. In FIG. 15, the horizontal axis represents the drying treatment time (minutes), and the vertical axis represents the circulation rate (%).

乾燥処理は、乾燥開始から処理終了時のｔ３まで実行される。図１５の場合、ｔ３は６０分である。段階設定制御方式においては、乾燥開始時には排気空気を全量排気（循環率０％）して乾燥処理が行われ、処理終了までの途中で、ｔ１、ｔ２時間が経過したとき、循環率をＣＲ１、ＣＲ２の２点に上昇変更される。図１５の場合、循環率ＣＲ１、ＣＲ２は、それぞれ約５５％、約７５％である。循環率１００％は、排気空気を全量、回転ドラムに戻す全量循環に対応する。 The drying process is executed from the start of drying to t3 at the end of the process. In the case of FIG. 15, t3 is 60 minutes. In the stage setting control method, the entire amount of exhaust air is exhausted (circulation rate 0%) at the start of drying, and the drying process is performed. It is changed to 2 points of CR2. In the case of FIG. 15, the circulation rates CR1 and CR2 are about 55% and about 75%, respectively. The circulation rate of 100% corresponds to the total circulation of the exhaust air returned to the rotating drum.

しかしながら、従来の段階設定制御方式による乾燥処理は、あらかじめ定めた乾燥処理時間内で乾燥過程で必要な乾燥条件の一部を監視しているだけであるので、無駄な処理時間を浪費して過乾燥を生じたり、逆に乾燥不足になったり良好な乾燥結果を得られないといった問題があった。 However, the drying process by the conventional stage setting control method only monitors a part of the drying conditions required in the drying process within the predetermined drying process time, so that the wasteful process time is wasted. There are problems such as drying, conversely insufficient drying, and poor drying results.

以下に、本発明に係る乾燥装置の実施形態を添付する図面に従って詳細に説明する。 Hereinafter, embodiments of the drying apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

図１は本実施形態に係る乾燥装置１の全体を示す。図２は正面側からみた乾燥装置１の概略構成を示す。 FIG. 1 shows the entire drying apparatus 1 according to the present embodiment. FIG. 2 shows a schematic configuration of the drying device 1 as viewed from the front side.

本実施形態に係る乾燥装置１は、洗濯装置（図示せず）により洗濯処理された洗濯物（被乾燥物）を乾燥処理するための回転ドラム式乾燥装置である。被乾燥物は、例えば、洗濯により再生使用される、マット、モップ、クロス等のダストコントロール商品である。 The drying device 1 according to the present embodiment is a rotary drum type drying device for drying the laundry (object to be dried) that has been washed by the washing device (not shown). The object to be dried is, for example, a dust control product such as a mat, a mop, or a cloth that is recycled by washing.

乾燥装置１は、本体部２と、被乾燥物を収容する回転ドラム３と、乾燥空気を回転ドラム３に導入する乾燥空気導入部４と、回転ドラム３内の空気を排気する排気部６と、排気空気を回転ドラム３に循環させる循環手段とを有する。回転ドラム３は、ドラム回転機構のローラー３９、４０（後述の図４参照）に支持されてドラム回転装置２６（後述の図３参照）により回転駆動可能に本体部２内に設置されている。回転ドラム３の側面には、多数の通気孔１５が穿設されている。通気孔１５を通じて回転ドラム３の内外に通風可能になっている。 The drying device 1 includes a main body 2, a rotary drum 3 for accommodating an object to be dried, a dry air introduction section 4 for introducing dry air into the rotary drum 3, and an exhaust section 6 for exhausting the air in the rotary drum 3. It also has a circulation means for circulating exhaust air to the rotating drum 3. The rotating drum 3 is supported in the rollers 39 and 40 of the drum rotation mechanism (see FIG. 4 to be described later) and is installed in the main body 2 so as to be rotationally driven by the drum rotating device 26 (see FIG. 3 to be described later). A large number of ventilation holes 15 are bored on the side surface of the rotary drum 3. It is possible to ventilate the inside and outside of the rotating drum 3 through the ventilation hole 15.

乾燥空気導入部４は、外気を取り込む開口部１８と、開口部１８の内側に設けた蒸気熱交換器１６およびフィルター５を有する。フィルター５を介して導入された外気は、蒸気熱交換器１６により加熱されて１００℃～１５０℃の高温の乾燥空気に変換されて通気孔１５を通じて回転ドラム３内に導入可能になっている。回転ドラム３は、高温乾燥空気を導入して中温湿潤空気を排気し、投入洗濯物の水分を回転ドラム３外へ排水するために、メッシュ状構造又は多数のパンチ孔構造の通気孔１５が形成されたドラム面構造を有している。 The dry air introduction portion 4 has an opening 18 for taking in outside air, and a steam heat exchanger 16 and a filter 5 provided inside the opening 18. The outside air introduced through the filter 5 is heated by the steam heat exchanger 16 and converted into high-temperature dry air having a temperature of 100 ° C. to 150 ° C., and can be introduced into the rotary drum 3 through the ventilation holes 15. The rotary drum 3 is formed with ventilation holes 15 having a mesh-like structure or a large number of punched holes in order to introduce high-temperature dry air to exhaust medium-temperature moist air and drain the moisture of the input laundry to the outside of the rotary drum 3. It has a drained drum surface structure.

循環手段は、本体部２の下部で、排気部６の下方に配設された送風ファン７を有する。本体部２の下部には、回転ドラム３の側面下部に対向した吸引部１３から本体部２底部を通じて回転ドラム３からの排気空気を送風ファン７に吸引可能な吸引経路Ｂが形成されている。 The circulation means has a blower fan 7 arranged below the exhaust portion 6 at the lower portion of the main body portion 2. A suction path B is formed in the lower portion of the main body 2 so that the exhaust air from the rotary drum 3 can be sucked into the blower fan 7 from the suction portion 13 facing the lower side surface of the rotary drum 3 through the bottom of the main body 2.

送風ファン７の駆動により、吸引部１３を通じて吸引した排気空気を排気部６側の上方に送風を生じさせることができる。この送風作用により本体部２側に負圧が生じて、開口部１８を通じて外気Ａの本体部２内への取り込みも行われる。吸引部１３下方には、箱状フィルター１４が設けられている。排気空気が送風ファン７に吸引されて箱状フィルター１４を通過するときに該排気空気に含有されたリント屑等の塵埃が箱状フィルター１４により回収、除去される。 By driving the blower fan 7, the exhaust air sucked through the suction section 13 can be blown upward on the exhaust section 6 side. Due to this blowing action, a negative pressure is generated on the main body 2 side, and the outside air A is also taken into the main body 2 through the opening 18. A box-shaped filter 14 is provided below the suction portion 13. When the exhaust air is sucked by the blower fan 7 and passes through the box-shaped filter 14, dust such as lint dust contained in the exhaust air is collected and removed by the box-shaped filter 14.

排気部６は、送風ファン７の送風口の上方に配設された排気ダクトにより構成されている。該排気ダクトの内部には、送風ファン７から排出、送風される排気空気Ｄを回転ドラム３内に循環させるための循環ダンパー８が配設されている。循環ダンパー８は、傾斜角度が可変な板片形状を有し、後述の図３に示す循環ダンパー装置２５の駆動により、水平状態から垂直状態に可変可能になっている。水平状態の場合、循環ダンパー８により排気空気Ｄの排気部６への進入経路が閉塞される。垂直状態の場合、排気空気Ｄは循環ダンパー８を障害とせずに外部に流出空気Ｅとして排出可能になる。 The exhaust unit 6 is composed of an exhaust duct arranged above the air outlet of the air fan 7. Inside the exhaust duct, a circulation damper 8 for circulating the exhaust air D discharged and blown from the blower fan 7 into the rotating drum 3 is provided. The circulation damper 8 has a plate piece shape with a variable inclination angle, and can be changed from a horizontal state to a vertical state by driving the circulation damper device 25 shown in FIG. 3 to be described later. In the horizontal state, the circulation damper 8 blocks the entry path of the exhaust air D to the exhaust portion 6. In the vertical state, the exhaust air D can be discharged to the outside as outflow air E without disturbing the circulation damper 8.

循環ダンパー８を所定の傾斜角度にすることにより、排気空気Ｄの一部を循環ダンパー８に当接させて、残りの排気空気を排気部６側に流出させることができる。循環ダンパー８に当接した排気空気は、風向きを変更されて、循環空気Ｃとして本体部２上方に設けた流入口１２より通気孔１５を通じて回転ドラム３内に再び流入する。循環ダンパー８の傾斜角度を可変することによって、流入口１２より回転ドラム３内に循環させる排気空気Ｄの流量の割合、つまり循環率を調整することができる。排気空気の循環量を調整する調整手段としては、循環ダンパー８に限らず、例えば、送風ファン７の送風側から流入口１２に至る送風経路と、該送風側から排気部６に至る排風経路とに開閉弁を設けて、該開閉弁の開度制御により循環量の調整を行うようにしてもよい。 By setting the circulation damper 8 at a predetermined inclination angle, a part of the exhaust air D can be brought into contact with the circulation damper 8 and the remaining exhaust air can be discharged to the exhaust portion 6 side. The exhaust air that comes into contact with the circulation damper 8 is changed in the direction of the wind and flows into the rotating drum 3 again from the inflow port 12 provided above the main body 2 as the circulating air C through the ventilation hole 15. By varying the inclination angle of the circulation damper 8, the ratio of the flow rate of the exhaust air D circulated from the inflow port 12 into the rotating drum 3, that is, the circulation rate can be adjusted. The adjusting means for adjusting the circulation amount of the exhaust air is not limited to the circulation damper 8, and for example, a blower path from the blower side of the blower fan 7 to the inflow port 12 and an exhaust path from the blower side to the exhaust unit 6. An on-off valve may be provided at the same time, and the circulation amount may be adjusted by controlling the opening of the on-off valve.

乾燥装置１の循環手段は、送風ファン７、循環ダンパー８および吸引経路Ｂにより構成され、乾燥装置１は、排気空気を吸引して回転ドラム３内に循環させる循環機能を備える。送風ファン７の送風口より上方には、排気空気の湿度を検知する湿度センサ９が設置されている。湿度センサ９は、排気空気の吸引経路Ｂ側に設けてもよい。開口部１８の近傍には、回転ドラム３への導入空気の温度を検知するための温度センサ２８が設置されている。なお、図示しないが、排気空気の温度を監視するための温度センサも湿度センサ９の近傍に設けられている。 The circulation means of the drying device 1 is composed of a blower fan 7, a circulation damper 8, and a suction path B, and the drying device 1 has a circulation function of sucking exhaust air and circulating it in the rotating drum 3. A humidity sensor 9 that detects the humidity of the exhaust air is installed above the air outlet of the air fan 7. The humidity sensor 9 may be provided on the suction path B side of the exhaust air. A temperature sensor 28 for detecting the temperature of the air introduced into the rotating drum 3 is installed in the vicinity of the opening 18. Although not shown, a temperature sensor for monitoring the temperature of the exhaust air is also provided in the vicinity of the humidity sensor 9.

図３は、乾燥装置１の制御部２０を示す。 FIG. 3 shows the control unit 20 of the drying device 1.

制御部２０は、ＣＰＵ２１と、乾燥処理プログラムを記憶するＲＯＭ２２と、ワーキングメモリのＲＡＭ２３を含むマイクロプロセッサにより構成されている。制御部２０は、プログラマブルロジックデバイス（ＰＬＤ）を用いて構成することもできる。 The control unit 20 includes a CPU 21, a ROM 22 for storing a drying processing program, and a microprocessor including a RAM 23 for a working memory. The control unit 20 can also be configured by using a programmable logic device (PLD).

制御部２０の入力側には、乾燥条件、乾燥処理操作等の入力を行うための入力手段２９と、湿度センサ９および温度センサ２８が接続されている。入力手段２９には、キー入力装置や液晶タッチパネル装置等を使用することができる。 An input means 29 for inputting drying conditions, a drying process operation, and the like, a humidity sensor 9 and a temperature sensor 28 are connected to the input side of the control unit 20. As the input means 29, a key input device, a liquid crystal touch panel device, or the like can be used.

制御部２０の出力側には、制御対象として、送風ファン７のファンモータ２４、循環ダンパー８の循環ダンパー装置２５、回転ドラム３のドラム回転装置２６および表示器２７が接続されている。循環ダンパー装置２５は、循環ダンパー８の回動軸を回転駆動するダンパー駆動モータのステッピングモータ（図示せず）を有する。 The fan motor 24 of the blower fan 7, the circulation damper device 25 of the circulation damper 8, the drum rotation device 26 of the rotary drum 3, and the display 27 are connected to the output side of the control unit 20 as control targets. The circulation damper device 25 has a stepping motor (not shown) of a damper drive motor that rotationally drives the rotation shaft of the circulation damper 8.

送風ファン７の送風量を調整するために、制御部２０からファンモータ２４に対してフ
ァン回転数に応じたファン回転数制御信号が出力可能になっている。送風ファン７のファン回転数データは、制御部２０から読み取って取得可能になっている。循環ダンパー８の角度設定を行うために、制御部２０から該ステッピングモータに対して設定角度に応じた角度制御信号が出力可能になっている。循環ダンパー装置２５は、受信した角度制御信号に基づいて該ステッピングモータを駆動して循環ダンパー８を所定の角度に回動させる。循環ダンパー８の角度で排気空気の循環率が定まるので、該角度制御信号により循環率制御が可能になっている。 In order to adjust the amount of air blown by the blower fan 7, the control unit 20 can output a fan rotation speed control signal according to the fan rotation speed to the fan motor 24. The fan rotation speed data of the blower fan 7 can be read and acquired from the control unit 20. In order to set the angle of the circulation damper 8, the control unit 20 can output an angle control signal according to the set angle to the stepping motor. The circulation damper device 25 drives the stepping motor based on the received angle control signal to rotate the circulation damper 8 to a predetermined angle. Since the circulation rate of the exhaust air is determined by the angle of the circulation damper 8, the circulation rate can be controlled by the angle control signal.

ドラム回転装置２６は、回転ドラム３を回転自在に軸支し、ローラー３９、４０を含むドラム回転機構と、回転ドラム３を回転駆動するドラム回転モータ（図示せず）と、該ドラム回転モータを駆動制御するモータ制御手段（図示せず）を有する。回転ドラム３を所定の回転数で回転させるために、制御部２０から該モータ制御手段に対して回転数に応じたドラム回転数制御信号が出力可能になっている。ドラム回転装置２６のドラム回転数データは、制御部２０から読み取って取得可能になっている。表示器２７は、液晶表示装置で構成され、制御部２０から表示データおよび表示指示制御信号を受信して、操作ガイダンス、設定データおよび乾燥処理データ等を表示する。 The drum rotation device 26 rotatably supports the rotary drum 3, and includes a drum rotation mechanism including rollers 39 and 40, a drum rotation motor (not shown) for rotationally driving the rotary drum 3, and the drum rotation motor. It has a motor control means (not shown) for drive control. In order to rotate the rotating drum 3 at a predetermined rotation speed, the control unit 20 can output a drum rotation speed control signal according to the rotation speed to the motor control means. The drum rotation speed data of the drum rotation device 26 can be read and acquired from the control unit 20. The display 27 is composed of a liquid crystal display device, receives display data and display instruction control signals from the control unit 20, and displays operation guidance, setting data, drying processing data, and the like.

図４は、乾燥装置１に用いる高温乾燥空気の供給系を示す。 FIG. 4 shows a supply system for high temperature dry air used in the drying device 1.

蒸気熱交換器１６には、蒸気発生部（ボイラー）３２で発生させた蒸気が蒸気導入管３５を介して導入可能になっている。蒸気熱交換器１６は、開口部１８から導入された常温（室温）外気を該蒸気により加熱して高温乾燥空気に変換することができる。蒸気発生部３２は、給水ポンプ３１を介して給水タンク３０が接続されている。給水ポンプ３１の駆動により、給水タンク３０に収納された加熱蒸気用水が供給管３４を通じて蒸気発生部３２に給水、供給可能になっている。給水タンク３０には、外部から供給水を補充する補給管３７が接続されている。蒸気熱交換器１６において発生するドレイン温水もドレイン回収管路３６を通じて回収され、給水タンク３０に回収可能になっている。 The steam generated by the steam generator (boiler) 32 can be introduced into the steam heat exchanger 16 via the steam introduction pipe 35. The steam heat exchanger 16 can heat the room temperature (room temperature) outside air introduced from the opening 18 with the steam and convert it into high temperature dry air. A water supply tank 30 is connected to the steam generation unit 32 via a water supply pump 31. By driving the water supply pump 31, the heated steam water stored in the water supply tank 30 can be supplied and supplied to the steam generation unit 32 through the supply pipe 34. A supply pipe 37 for replenishing supply water from the outside is connected to the water supply tank 30. The drain hot water generated in the steam heat exchanger 16 is also recovered through the drain recovery pipe 36 and can be recovered in the water supply tank 30.

蒸気導入管３５の途中には電磁開閉バルブ３３が設けられている。電磁開閉バルブ３３は、制御部２０から出力されるバルブ制御信号ＳＶによりバルブ開閉やバルブ開口面積が制御可能になっている。電磁開閉バルブ３３の駆動制御により蒸気供給の開始・停止を制御するとともに蒸気流量の調整を行うことができる。温度センサ２８により計測された導風温度と入力された設定値（温度、蒸気流量、時間など）に基づいて、制御部２０からのバルブ制御信号ＳＶにより電磁開閉バルブ３３の開閉や開口面積を制御することによって蒸気熱交換器１６の加熱温度の制御が可能になっている。 An electromagnetic on-off valve 33 is provided in the middle of the steam introduction pipe 35. The electromagnetic opening / closing valve 33 can control the valve opening / closing and the valve opening area by the valve control signal SV output from the control unit 20. By controlling the drive of the electromagnetic on-off valve 33, it is possible to control the start / stop of steam supply and adjust the steam flow rate. Based on the air guide temperature measured by the temperature sensor 28 and the input set values (temperature, steam flow rate, time, etc.), the opening / closing and opening area of the electromagnetic opening / closing valve 33 are controlled by the valve control signal SV from the control unit 20. By doing so, it is possible to control the heating temperature of the steam heat exchanger 16.

回転ドラム３は、ドラム内に被乾燥物を投入、収容可能な開閉部（図示せず）を有する。該開閉部を開けて投入、収容される被乾燥物は、別の処理設備において既に洗濯・すすぎ・脱水工程が完了して乾燥処理で再生完了になる状態にある。回転ドラム３の回転駆動により、ドラム内の投入被乾燥物は、回転ドラム３の上部まで強制的に引き上げられ、上部に到達すると落下するように撹拌、混ぜ返されてドラム内を移動する。回転ドラム３内に導入された高温乾燥空気は、回転ドラム３内で掻き上げられて落下する被乾燥物に接触して、被乾燥物の水分を強制蒸発させて乾燥処理を行うことができる。回転ドラム３の内面には、掻上部材４１が突設されており、投入被乾燥物を掻上部材４１により上部へ引上げ可能になっている。 The rotary drum 3 has an opening / closing portion (not shown) capable of charging and accommodating an object to be dried in the drum. The object to be dried, which is charged and stored by opening the opening / closing portion, is in a state where the washing / rinsing / dehydrating steps have already been completed in another processing facility and the regeneration is completed in the drying process. By the rotary drive of the rotary drum 3, the material to be charged in the drum is forcibly pulled up to the upper part of the rotary drum 3, and when it reaches the upper part, it is stirred and mixed so as to fall and moves in the drum. The high-temperature dry air introduced into the rotary drum 3 comes into contact with the object to be dried that is scraped up and falls in the rotary drum 3, and the moisture of the object to be dried can be forcibly evaporated to perform the drying process. A scraping member 41 is provided so as to project from the inner surface of the rotary drum 3, and the material to be charged can be pulled up by the scraping member 41.

The control process in the present embodiment is indicated by a step S number, and the process in each step constitutes a control means whose execution is controlled under the control of the control unit 20.

電源投入時には、制御部２０の初期化処理（ステップＳ１）が実行される。初期化処理を終えると、正常動作時の処理（ステップＳ２～Ｓ４）が実行される。 When the power is turned on, the initialization process (step S1) of the control unit 20 is executed. When the initialization process is completed, the process during normal operation (steps S2 to S4) is executed.

データ設定処理（ステップＳ２）において、乾燥制御実行処理に用いる乾燥処理用制御データの入力および乾燥処理実行のための乾燥コースの入力を行うことができる。乾燥処理用制御データを入力した場合、入力制御データはＲＯＭ２２に記憶、設定される。乾燥コースの入力を行った場合、乾燥コースの入力データはＲＡＭ２３に記憶、設定される。この他の入力可能項目として乾燥終了条件の入力が可能である。 In the data setting process (step S2), the control data for the drying process used for the drying control execution process can be input and the drying course for executing the drying process can be input. When the control data for drying processing is input, the input control data is stored and set in the ROM 22. When the drying course is input, the input data of the drying course is stored and set in the RAM 23. As another inputtable item, the drying end condition can be input.

乾燥コースは、モップやマット等のダストコントロール商品の種別（カテゴリー）に応じて入力可能になっている。乾燥終了条件は、排気空気の湿度を目標値として設定可能である。目標値の湿度は、１単位（１ｇ／ｍ3）で任意に設定可能であり、本実施例の場合、２１ｇ／ｍ3に設定している。 The drying course can be entered according to the type (category) of dust control products such as mops and mats. The drying end condition can be set with the humidity of the exhaust air as the target value. The humidity of the target value can be arbitrarily set in 1 unit (1 g / m 3 ), and in the case of this embodiment, it is set to 21 g / m 3 .

監視データ取得処理（ステップＳ３）において、制御部２０の制御下で監視データとして、例えば、排気空気に対して湿度センサ９により計測した計測湿度データおよび回転ドラム３への導入空気に対して温度センサ２８により計測した計測温度データが取り込まれてＲＡＭ２３の所定エリアに記憶される。 In the monitoring data acquisition process (step S3), as monitoring data under the control of the control unit 20, for example, the measured humidity data measured by the humidity sensor 9 for the exhaust air and the temperature sensor for the introduced air to the rotating drum 3. The measured temperature data measured by 28 is taken in and stored in a predetermined area of the RAM 23.

乾燥制御実行処理（ステップＳ４）において、入力設定された乾燥条件および監視データに基づいてＲＯＭ２２に格納した乾燥処理プログラムを実行することにより被乾燥物に対する乾燥処理の実行制御が行われる。 In the drying control execution process (step S4), the execution control of the drying process for the object to be dried is performed by executing the drying process program stored in the ROM 22 based on the input set drying conditions and the monitoring data.

図６および図７は、乾燥制御実行処理（ステップＳ４）の処理内容および処理手順を示す。 6 and 7 show the processing contents and processing procedure of the drying control execution processing (step S4).

ＲＯＭ２２には、乾燥制御実行処理に用いる乾燥処理プログラムおよび該乾燥処理プログラムの処理実行に用いる乾燥処理の制御データが格納されている。ＲＯＭ２２に格納した乾燥処理プログラムおよび制御データは、乾燥装置１専用にせずに、所定の記憶媒体（例えば、メモリデバイス、ＣＤ－ＲＯＭ、ＤＶＤ、モバイル機器等）に記憶、保存し、別に創設した乾燥装置の制御部に、該記憶媒体を介してインストール可能にすることができる。 The ROM 22 stores a drying process program used for the drying control execution process and control data of the drying process used for executing the process of the drying process program. The drying process program and control data stored in the ROM 22 are stored and stored in a predetermined storage medium (for example, a memory device, a CD-ROM, a DVD, a mobile device, etc.) without being dedicated to the drying device 1, and the drying is separately created. It can be installed in the control unit of the device via the storage medium.

図８～図１０は、乾燥処理の制御データ例を示す。これらの制御データには、カテゴリーＡ、Ｂ、Ｃ別の３種のデータが含まれている。 8 to 10 show an example of control data of the drying process. These control data include three types of data according to categories A, B, and C.

図９の（９Ａ）、（９Ｂ）は、乾燥過程における計測湿度（ｇ／ｍ3）に応じた必要風量よりのファンモーター２４の回転数（ｒｐｍ）との関係を示すファン回転数制御データと、その関係を示す計測湿度－ファン回転数のグラフである。 9A and 9B of FIG. 9 are fan rotation speed control data showing the relationship with the rotation speed (rpm) of the fan motor 24 from the required air volume according to the measured humidity (g / m 3 ) in the drying process. , It is a graph of the measured humidity-fan rotation speed showing the relationship.

図１０の（１０Ａ）、（１０Ｂ）は、乾燥過程における計測湿度（ｇ／ｍ3）に応じた被乾燥物重量よりの回転ドラム３の回転数（ｒｐｍ）との関係を示すドラム回転数制御データと、その関係を示す計測湿度－ドラム回転数のグラフである。 FIGS. 10A and 10B show a drum rotation speed control showing the relationship between the rotation speed (rpm) of the rotating drum 3 and the weight of the object to be dried according to the measured humidity (g / m 3 ) in the drying process. It is a graph of the measured humidity-drum rotation speed showing the data and the relationship.

これらの制御データ（循環率制御データ、ファン回転数制御データ、ドラム回転数制御データ）は、あらかじめ行った検証実験により得られたものである。検証実験は、カテゴ
リー別のテスト用被乾燥物を用いて種々乾燥条件（循環率、ファン回転数、ドラム回転数）を変えて実施され、種々の検証実験結果からカテゴリー別製品（被乾燥物）には排気空気の湿度が特有の変化を示す特性（カテゴリーごとの３点比例制御線）を見出すことができ、過乾燥や乾燥不足がなく、風合いに優れた乾燥条件をあらかじめ求めて得られた制御データが図８～図１０に示すデータである。本実施形態においては、ダストコントロール商品の形態別に分類し、各分類ごとの無段階制御因子（パラメータ）として、循環率、ファン回転数およびドラム回転数の１または２以上を使用可能になっている。 These control data (circulation rate control data, fan rotation speed control data, drum rotation speed control data) were obtained by verification experiments performed in advance. The verification experiment was carried out by using the test object to be tested by category and changing various drying conditions (circulation rate, fan rotation speed, drum rotation speed), and from the results of various verification experiments, the product by category (dry object). It was possible to find a characteristic (three-point proportional control line for each category) in which the humidity of the exhaust air shows a peculiar change. The control data is the data shown in FIGS. 8 to 10. In the present embodiment, the dust control products are classified according to the form, and one or two or more of the circulation rate, the fan rotation speed, and the drum rotation speed can be used as the stepless control factor (parameter) for each classification.

各制御データは、２点の基準湿度と、それらの中間点の湿度における制御対象（循環率、ファン回転数またはドラム回転数）のデータで構成され、３点の比例制御（ＰＩＤ）方法を用いて監視湿度に応じた制御対象の無段階制御を行うことができる。例えば、図８の循環率制御データの場合、カテゴリーＡ、Ｂでは基準湿度の下限値α、上限値βを２１、４３（ｇ／ｍ3）とし、中間点湿度を３２（ｇ／ｍ3）としている。カテゴリーＣでは基準湿度の下限値α、上限値βを２１、５１（ｇ／ｍ3）とし、中間点湿度を３２（ｇ／ｍ3）としている。図９、図１０の制御データの場合も図８の場合と同様の基準湿度と中間点湿度になっている。 Each control data consists of two reference humidity points and control target (circulation rate, fan rotation speed or drum rotation speed) data at the humidity at the midpoint of them, and uses a three-point proportional control (PID) method. It is possible to perform stepless control of the controlled object according to the monitored humidity. For example, in the case of the circulation rate control data in FIG. 8, in categories A and B, the lower limit value α and the upper limit value β of the reference humidity are set to 21, 43 (g / m 3 ), and the intermediate point humidity is 32 (g / m 3 ). It is supposed to be. In category C, the lower limit value α and the upper limit value β of the reference humidity are 21, 51 (g / m 3 ), and the midpoint humidity is 32 (g / m 3 ). In the case of the control data of FIGS. 9 and 10, the reference humidity and the intermediate point humidity are the same as in the case of FIG.

本実施形態においては、乾燥制御処理の開始条件は、計測湿度が基準湿度の上限値βに到達したことにより成立し、乾燥制御処理の終了条件は、計測湿度が基準湿度の下限値αに到達したことにより成立する。上記の基準湿度の下限値α（２１ｇ／ｍ3）は、乾燥終了条件の目標値に対応している。ＲＯＭ２２には、図８～図９の制御データ以外にも、１単位（１ｇ／ｍ3）ずつ異なる基準湿度の下限値によるカテゴリー別制御データが格納されている。すなわち、データ設定処理（ステップＳ２）において、カテゴリー別の目標値を、１単位（１ｇ／ｍ3）別に設定することができる。設定した終了条件に応じたカテゴリー別制御データに基づいて、３点の比例制御方法による監視湿度に応じた制御対象の無段階制御が実行可能になっている。 In the present embodiment, the start condition of the drying control process is satisfied when the measured humidity reaches the upper limit value β of the reference humidity, and the end condition of the drying control process is the end condition of the measured humidity reaching the lower limit value α of the reference humidity. It is established by doing. The lower limit value α (21 g / m 3 ) of the above reference humidity corresponds to the target value of the drying end condition. In addition to the control data shown in FIGS. 8 to 9, the ROM 22 stores category-specific control data according to the lower limit value of the reference humidity, which differs by one unit (1 g / m 3 ). That is, in the data setting process (step S2), the target value for each category can be set for each unit (1 g / m 3 ). Based on the control data for each category according to the set end condition, stepless control of the controlled object according to the monitoring humidity by the three-point proportional control method can be executed.

本発明においては、３点の比例制御に限らず、２点の基準湿度における制御対象での２点の比例制御方法を使用することができる。また、本発明においては、比例制御に限らず、３点または４点以上を近似曲線で結ぶ曲線制御方法を使用することができる。 In the present invention, not only the proportional control of three points but also the proportional control method of two points in the controlled object at the reference humidity of two points can be used. Further, in the present invention, not only proportional control but also a curve control method connecting three points or four or more points with an approximate curve can be used.

乾燥制御実行処理の実行に先立って、乾燥コースの設定入力が行われる。乾燥コースの設定入力は、表示器２７に設定入力画面（図示せず）を表示させて入力手段２９によるキー操作で行う。乾燥コースの設定により、被乾燥物のカテゴリー別の乾燥条件による乾燥制御処理が実行可能になる。本実施形態においては、終了条件を下限値αの湿度値２１（ｇ／ｍ3）とした場合、図８の制御データに基づく循環率制御態様、図９の制御データに基づくファン回転数制御態様および図１０の制御データに基づくドラム回転数制御態様の３種の乾燥制御処理（ステップＳ１６、Ｓ１８、Ｓ２０）がパラレル処理可能になっている。制御態様の種別も入力可能項目として循環率、ファン回転数およびドラム回転数のうち１または２以上を選択して設定可能にすることができ、あるいは循環率制御態様は常時実行可能にし、ファン回転数制御態様および／またはドラム回転数制御態様をオプション項目として追加設定可能にしてもよい。 Prior to the execution of the drying control execution process, the setting input of the drying course is performed. The setting input of the drying course is performed by displaying the setting input screen (not shown) on the display 27 and operating the keys by the input means 29. By setting the drying course, it becomes possible to execute the drying control process according to the drying conditions for each category of the object to be dried. In the present embodiment, when the end condition is the humidity value 21 (g / m 3 ) of the lower limit value α, the circulation rate control mode based on the control data of FIG. 8 and the fan rotation speed control mode based on the control data of FIG. And three types of drying control processing (steps S16, S18, S20) of the drum rotation speed control mode based on the control data of FIG. 10 can be processed in parallel. The type of control mode can also be set by selecting one or two or more of the circulation rate, fan rotation speed, and drum rotation speed as inputtable items, or the circulation rate control mode can always be executed and the fan rotation can be performed. The number control mode and / or the drum rotation speed control mode may be additionally set as an optional item.

乾燥コースの設定が行われている場合（ステップＳ１１）、入力手段２９の乾燥処理の開始操作キーを操作することにより乾燥装置１による乾燥処理の実行が開始される（ステップＳ１２、Ｓ１３）。 When the drying course is set (step S11), the drying process is started by the drying device 1 by operating the drying process start operation key of the input means 29 (steps S12 and S13).

乾燥開始処理（ステップＳ１３）において、ファンモータ２４、循環ダンパー装置２５、ドラム回転装置２６等の駆動源が起動される。ついで、設定された乾燥コースの判別が行われて、ＲＡＭ２３に設けたフラグエリアにコース別実行フラグがオンにセットされる
。乾燥開始により、排気空気の循環は全量排気（循環率０％）で乾燥処理が始まる。乾燥開始後、高温乾燥空気の導入により排気空気の湿度は上昇していき、排気空気の湿度変化を監視して、計測湿度が基準値の上限値βに到達した場合（ステップＳ１４）、設定されたカテゴリー別の循環率制御態様（ステップＳ１６、Ｓ１７）、ファン回転数制御態様（ステップＳ１８、Ｓ１９）および回転数制御態様（ステップＳ２０、Ｓ２１）の乾燥制御処理がパラレル処理により実行可能になる。 In the drying start process (step S13), drive sources such as the fan motor 24, the circulation damper device 25, and the drum rotation device 26 are activated. Then, the set drying course is discriminated, and the course-specific execution flag is set to ON in the flag area provided in the RAM 23. With the start of drying, the exhaust air is fully exhausted (circulation rate 0%) and the drying process is started. After the start of drying, the humidity of the exhaust air rises due to the introduction of high-temperature dry air, and when the humidity change of the exhaust air is monitored and the measured humidity reaches the upper limit β of the reference value, it is set (step S14). The drying control processing of the circulation rate control mode (steps S16, S17), the fan rotation speed control mode (steps S18, S19) and the rotation speed control mode (steps S20, S21) for each category can be executed by the parallel processing.

各乾燥制御処理において、判定用データ取込処理（ステップＳ１５）、判定用データと制御データとに基づいて実行される判定処理（ステップＳ１６、Ｓ１９、Ｓ２２）、判定結果により乾燥条件の変更が必要な場合に実行される乾燥条件の変更処理（ステップＳ１８、Ｓ２１、Ｓ２４）が行われる。判定用データ取込処理（ステップＳ１５）において各制御態様に共通するデータとして湿度センサ９の出力信号による計測湿度データが取り込まれてＲＡＭ２３の所定エリアに記憶される。なお、以下の乾燥制御処理は、終了条件が湿度２１ｇ／ｍ3に設定されている設定ケースで説明する。 In each drying control process, it is necessary to change the drying conditions depending on the determination data acquisition process (step S15), the determination process executed based on the determination data and the control data (steps S16, S19, S22), and the determination result. In this case, the drying condition change process (steps S18, S21, S24) is performed. In the determination data acquisition process (step S15), the measured humidity data by the output signal of the humidity sensor 9 is taken in as data common to each control mode and stored in a predetermined area of the RAM 23. The following drying control process will be described in a setting case in which the end condition is set to a humidity of 21 g / m 3 .

循環率制御態様による乾燥制御処理においては、循環ダンパー８の角度設定のための角度制御信号から変換テーブル（図示せず）を参照して変換、抽出された循環率データが判定用データとしてＲＡＭ２３の所定エリアに取り込まれる（ステップＳ１５）。該変換テーブルは、あらかじめＲＯＭ２２に格納されている。循環率データは、角度制御信号データから所定のアルゴリズムにより演算して求めるようにしてもよい。 In the drying control process according to the circulation rate control mode, the circulation rate data converted and extracted from the angle control signal for setting the angle of the circulation damper 8 with reference to the conversion table (not shown) is used as the determination data in the RAM 23. It is taken into a predetermined area (step S15). The conversion table is stored in ROM 22 in advance. The circulation rate data may be obtained by calculating from the angle control signal data by a predetermined algorithm.

循環率判定処理（ステップＳ１６）は、図８に示す計測湿度－循環率の比例制御線を参照し、取り込んだ計測湿度データおよび循環率データに基づき、計測湿度に対応する比例制御線上の循環率と、取り込んだ現在の循環率とを比較し、それらの差値が許容幅内にあるか否かを判断し、現在の循環率が該許容幅を超えている場合、循環率を比例制御線上の循環率に変更する変更要と判定して、常に比例制御線に従った最適循環率に、ＲＡＭ２３に設けた実行循環率パラメータ値のデータエリアに対する上書き補正による変更を行うことができる。現在の循環率が該許容幅内にある場合（ステップＳ１７）、循環率の変更不要と判定する。変更要の場合、比例制御線上の循環率に変更するように循環ダンパー装置２５に角度制御信号が出力される（ステップＳ１８）。 The circulation rate determination process (step S16) refers to the measured humidity-circulation rate proportional control line shown in FIG. 8, and based on the captured measured humidity data and the circulation rate data, the circulation rate on the proportional control line corresponding to the measured humidity. And the current circulation rate taken in, it is judged whether or not the difference between them is within the allowable range, and if the current circulation rate exceeds the allowable range, the circulation rate is on the proportional control line. It is possible to determine that it is necessary to change to the circulation rate of, and to always change the optimum circulation rate according to the proportional control line by overwriting and correcting the data area of the execution circulation rate parameter value provided in the RAM 23. When the current circulation rate is within the allowable range (step S17), it is determined that the circulation rate does not need to be changed. When a change is required, an angle control signal is output to the circulation damper device 25 so as to change to the circulation rate on the proportional control line (step S18).

循環率判定処理（ステップＳ１６）と並行して実行されるファン回転数判定処理（ステップＳ１９）において、図９に示す計測湿度－ファン回転数の比例制御線を参照し、取り込んだ計測湿度データおよびファン回転数データに基づき、計測湿度に対応する比例制御線上のファン回転数と、取り込んだ現在のファン回転数とを比較し、それらの差値が許容幅内にあるか否かを判断し、現在のファン回転数が該許容幅を超えている場合、ファン回転数を比例制御線上のファン回転数に変更する変更要と判定して、常に比例制御線に従った最適ファン回転数に、ＲＡＭ２３に設けた実行ファン回転数パラメータ値のデータエリアに対する上書き補正による変更を行うことができる。現在のファン回転数が該許容幅内にある場合（ステップＳ２０）、ファン回転数の変更不要と判定する。変更要の場合、比例制御線上のファン回転数に変更するようにファンモータ２４にファン回転数制御信号が出力される（ステップＳ２１）。 In the fan rotation speed determination process (step S19) executed in parallel with the circulation rate determination process (step S16), the measured humidity data captured by referring to the proportional control line of the measured humidity-fan rotation speed shown in FIG. 9 and Based on the fan rotation speed data, the fan rotation speed on the proportional control line corresponding to the measured humidity is compared with the current fan rotation speed captured, and it is determined whether or not the difference between them is within the allowable range. When the current fan rotation speed exceeds the allowable range, it is determined that the fan rotation speed needs to be changed to the fan rotation speed on the proportional control line, and the RAM 23 always sets the optimum fan rotation speed according to the proportional control line. It is possible to change the data area of the execution fan rotation speed parameter value provided in the above by overwriting correction. When the current fan rotation speed is within the allowable range (step S20), it is determined that the fan rotation speed does not need to be changed. When a change is required, a fan rotation speed control signal is output to the fan motor 24 so as to change to the fan rotation speed on the proportional control line (step S21).

循環率判定処理（ステップＳ１６）およびファン回転数判定処理（ステップＳ１９）と並行して実行されるドラム回転数判定処理（ステップＳ２２）において、図１０に示す計測湿度－ドラム回転数の比例制御線を参照し、取り込んだ計測湿度データおよびドラム回転数データに基づき、計測湿度に対応する比例制御線上のドラム回転数と、取り込んだ現在のドラム回転数とを比較し、それらの差値が許容幅内にあるか否かを判断し、現在のドラム回転数が該許容幅を超えている場合、ドラム回転数を比例制御線上のドラム回転数に変更する変更要と判定して、常に比例制御線に従った最適ドラム回転数に、ＲＡＭ２３に
設けた実行ドラム回転数パラメータ値のデータエリアに対する上書き補正による変更を行うことができる。現在のドラム回転数が該許容幅内にある場合（ステップＳ２３）、ドラム回転数の変更不要と判定する。変更要の場合、比例制御線上のドラム回転数に変更するようにドラム回転装置２６にドラム回転数制御信号が出力される（ステップＳ２４）。 In the drum rotation speed determination process (step S22) executed in parallel with the circulation rate determination process (step S16) and the fan rotation speed determination process (step S19), the proportional control line of the measured humidity-drum rotation speed shown in FIG. Based on the captured measured humidity data and drum rotation speed data, compare the drum rotation speed on the proportional control line corresponding to the measured humidity with the current drum rotation speed captured, and the difference between them is the allowable range. If the current drum rotation speed exceeds the allowable range, it is determined that it is necessary to change the drum rotation speed to the drum rotation speed on the proportional control line, and the proportional control line is always used. The optimum drum rotation speed according to the above can be changed by overwriting correction for the data area of the execution drum rotation speed parameter value provided in the RAM 23. When the current drum rotation speed is within the allowable range (step S23), it is determined that the drum rotation speed does not need to be changed. When a change is required, a drum rotation speed control signal is output to the drum rotation speed device 26 so as to change to the drum rotation speed on the proportional control line (step S24).

排気空気の湿度監視下で図８の制御データに基づく循環率制御態様、図９の制御データに基づくファン回転数制御態様および図１０の制御データに基づくドラム回転数制御態様の３種の乾燥制御処理（ステップＳ１６、Ｓ１８、Ｓ２０）が無段階制御により実行され、該乾燥制御処理は乾燥終了条件が成立するまで継続実行される（ステップＳ２５）。乾燥制御処理が継続実行された結果、監視湿度が基準湿度の下限値αに達した場合、乾燥終了条件が成立し、乾燥制御処理を終了する。乾燥終了条件が成立した場合、乾燥終了処理（ステップＳ２６）が実行される。乾燥終了処理において、電磁開閉バルブ３３を閉成して空気加熱用の蒸気供給を停止し、乾燥制御終了時に循環率が０％である場合を除き、循環ダンパー装置２５を駆動して全量排気状態に切り替えられる。乾燥終了処理の実行により、循環率が０％の状態で回転ドラム３を所定時間、クーリング回転させて収容している被乾燥物の冷却が行われる。該所定時間の経過後、ファンモータ２４およびドラム回転装置２６の駆動を停止して乾燥終了処理は終了する。以上の乾燥処理の終了によって、回転ドラム３を開いて乾燥済みの収容物の回収作業が行われる。 Under the humidity monitoring of the exhaust air, there are three types of drying control: a circulation rate control mode based on the control data of FIG. 8, a fan rotation speed control mode based on the control data of FIG. 9, and a drum rotation speed control mode based on the control data of FIG. The process (steps S16, S18, S20) is executed by stepless control, and the drying control process is continuously executed until the drying end condition is satisfied (step S25). As a result of continuous execution of the drying control process, when the monitored humidity reaches the lower limit value α of the reference humidity, the drying end condition is satisfied and the drying control process is terminated. When the drying end condition is satisfied, the drying end process (step S26) is executed. In the drying end process, the electromagnetic on-off valve 33 is closed to stop the steam supply for air heating, and the circulation damper device 25 is driven to exhaust the entire amount unless the circulation rate is 0% at the end of the drying control. Can be switched to. By executing the drying end process, the rotating drum 3 is cooled and rotated for a predetermined time in a state where the circulation rate is 0% to cool the object to be dried. After the lapse of the predetermined time, the driving of the fan motor 24 and the drum rotating device 26 is stopped, and the drying end process is completed. Upon completion of the above drying process, the rotary drum 3 is opened to collect the dried contents.

本実施形態に係る乾燥装置１によれば、第1記憶手段である、ＲＯＭ２２の循環率制御データ記憶エリアに、乾燥過程における湿度センサ９の計測湿度に応じた排気経路Ｂの排気風の循環率との関係をあらかじめ求めて、その関係を示す循環率制御データ（図８参照）を記憶し、循環率調整制御手段（ステップＳ１６～Ｓ１８）により、該循環率制御データに基づいて、計測湿度に応じて循環率を無段階で調整制御するので、排気空気の湿度が高い時点では乾燥促進のために排気空気の循環量を抑えて外部に排気する外部排気風量を増やし、監視湿度の降下に伴い排気空気の循環量を増加させ、外部排気風量を減少させる無段階制御を行うことができる。したがって、本実施形態において、循環率制御データと計測湿度によって被乾燥物の乾燥進行状態（乾燥具合）に追随しながら排気空気の循環量を調整でき、乾燥不足や過乾燥による乾燥不良を生ずることなく、乾燥に要する乾燥装置の駆動電力等のエネルギー消費を効率的に行え、被乾燥物に応じて適切な乾燥条件で良質の乾燥を行える乾燥条件自動追随型の乾燥制御装置を実現することができる。特に、監視項目としてｇ／ｍ3 単位の絶対湿度の排気湿度を監視データとして用いるので、相対湿度（％）や排気温度（℃）、被乾燥物の赤外線センサーによる検知温度（℃）を使用する場合と比較しても変化量を顕著にさせることができ綿密な無段階制御を行うことができる。 According to the drying device 1 according to the present embodiment, the circulation rate of the exhaust air of the exhaust path B according to the measured humidity of the humidity sensor 9 in the drying process in the circulation rate control data storage area of the ROM 22 which is the first storage means. The relationship with the humidity is obtained in advance, the circulation rate control data (see FIG. 8) showing the relationship is stored, and the measurement humidity is determined by the circulation rate adjustment control means (steps S16 to S18) based on the circulation rate control data. Since the circulation rate is adjusted and controlled steplessly according to it, when the humidity of the exhaust air is high, the circulation amount of the exhaust air is suppressed to promote drying and the amount of external exhaust air to be exhausted to the outside is increased. Stepless control can be performed to increase the circulation amount of the exhaust air and decrease the amount of the external exhaust air. Therefore, in the present embodiment, the circulation amount of the exhaust air can be adjusted while following the drying progress state (drying condition) of the object to be dried by the circulation rate control data and the measured humidity, and drying failure due to insufficient drying or overdrying occurs. It is possible to realize a drying condition automatic follow-up type drying control device that can efficiently consume energy such as driving power of the drying device required for drying and can perform high quality drying under appropriate drying conditions according to the object to be dried. can. In particular, since the exhaust humidity of the absolute humidity in g / m 3 units is used as the monitoring data, the relative humidity (%), the exhaust temperature (° C), and the temperature detected by the infrared sensor of the object to be dried (° C) are used. The amount of change can be made remarkable even when compared with the case, and detailed stepless control can be performed.

乾燥装置１によれば、第２記憶手段である、ＲＯＭ２２のファン回転数制御データ記憶エリアに、乾燥過程における計測湿度に応じた必要風量よりのファンモーターの回転数との関係をあらかじめ求めて、その関係を示すファン回転数制御データ（図９参照）を記憶し、ファン回転数調整制御手段（ステップＳ１９～Ｓ２１）により、ファン回転数制御データに基づいて、計測湿度に応じてファンモーター２４の回転数を無段階で調整制御するので、排気空気の湿度変化に追随して排気空気の循環量の増減を微調整可能になり、ファン回転数制御データと計測湿度によって被乾燥物の乾燥進行状態に追随しながらファンモーター２４の回転数（すなわち、送風風量）を常に最適に調整して、乾燥不足や過乾燥による乾燥不良を生ずることなく、乾燥に要する乾燥装置の駆動電力等のエネルギー消費を効率的に行え、被乾燥物に応じて適切な乾燥条件で良質の乾燥を行える乾燥条件自動追随型の乾燥制御装置を実現することができる。 According to the drying device 1, the relationship between the fan motor rotation speed and the required air volume according to the measured humidity in the drying process is obtained in advance in the fan rotation speed control data storage area of the ROM 22 which is the second storage means. The fan rotation speed control data (see FIG. 9) showing the relationship is stored, and the fan rotation speed adjustment control means (steps S19 to S21) of the fan motor 24 according to the measured humidity based on the fan rotation speed control data. Since the rotation speed is adjusted and controlled steplessly, it is possible to finely adjust the increase or decrease in the circulation amount of the exhaust air according to the humidity change of the exhaust air, and the drying progress state of the object to be dried is based on the fan rotation speed control data and the measured humidity. By always optimally adjusting the rotation speed (that is, the amount of air blown air) of the fan motor 24 while following the above, energy consumption such as driving power of the drying device required for drying can be reduced without causing insufficient drying or poor drying due to overdrying. It is possible to realize a drying condition automatic follow-up type drying control device that can efficiently perform and perform high-quality drying under appropriate drying conditions according to the object to be dried.

乾燥装置１によれば、第３記憶手段である、ＲＯＭ２２のドラム回転数制御データ記憶エリアに、乾燥過程における計測湿度に応じた被乾燥物重量よりの前記回転ドラムの回転数との関係をあらかじめ求めて、その関係を示すドラム回転数制御データ（図１０参照）
を記憶し、ドラム回転数調整制御手段（ステップＳ２２～Ｓ２４）により、ドラム回転数制御データに基づいて、計測湿度に応じてドラム回転装置２６のドラムモーターの回転数を無段階で調整制御するので、ドラム回転数制御データと計測湿度によって被乾燥物の乾燥進行状態に追随しながら回転ドラム３の回転数（すなわち、被乾燥物の乾燥促進に伴う重量減少よりの、ドラム内の通風量と被乾燥物の撹拌度合い）を常に最適に調整して、乾燥不足や過乾燥による乾燥不良を生ずることなく、乾燥に要する乾燥装置の駆動電力等のエネルギー消費を効率的に行え、被乾燥物に応じて適切な乾燥条件で良質の乾燥を行える乾燥条件自動追随型の乾燥制御装置を実現することができる。 According to the drying device 1, in the drum rotation speed control data storage area of the ROM 22 which is the third storage means, the relationship between the rotation speed of the rotating drum and the weight of the object to be dried according to the measured humidity in the drying process is determined in advance. Drum rotation speed control data (see FIG. 10) that is obtained and shows the relationship.
Is stored, and the drum rotation speed adjustment control means (steps S22 to S24) adjusts and controls the rotation speed of the drum motor of the drum rotation device 26 steplessly according to the measured humidity based on the drum rotation speed control data. , Drum rotation speed control data and measured humidity keeps up with the drying progress state of the object to be dried, and the rotation speed of the rotating drum 3 (that is, the amount of ventilation in the drum and the subject due to the weight reduction due to the acceleration of drying of the object to be dried). The degree of agitation of the dried product) is always optimally adjusted to efficiently consume energy such as the drive power of the drying device required for drying without causing insufficient drying or drying defects due to overdrying, depending on the object to be dried. It is possible to realize a drying condition automatic follow-up type drying control device that can perform high-quality drying under appropriate drying conditions.

モップ製品の乾燥処理は、目標値の排気湿度の下限値αとして２０ｇ／ｍ3に設定して実施された。（１１Ａ）の排気湿度特性に示すように、高温乾燥空気の導入開始後、排気湿度は、開始時の１０ｇ／ｍ3から徐々に上昇して６０ｇ／ｍ3を超えた時点から下降し（乾燥１段目）、乾燥促進に伴って乾燥２段目、３段目を経て目標値（２０ｇ／ｍ3）に到達している。マット製品の乾燥処理は、目標値の排気湿度の下限値αとして１５ｇ／ｍ3に設定して実施された。（１３Ａ）の排気湿度特性に示すように、高温乾燥空気の導入開始後、排気湿度は、開始時の１０ｇ／ｍ3から徐々に上昇して３７ｇ／ｍ3を超えた時点から下降し（乾燥１段目）、乾燥促進に伴って乾燥２段目、３段目を経て目標値（１５ｇ／ｍ3）に到達している。図１１～図１４から、モップ製品およびマット製品に対して実施した乾燥処理からわかるように、図１５に示した、燥処理時間の監視下で行う従来の段階式乾燥制御方式と比較して、破線で示した従来の段階式乾燥制御方式よりも本発明に係る乾燥条件自動追随型の乾燥方法の場合には、排気空気の循環率、ファン回転数がきめ細かに実行されていることがわかる。湿度変化に的確に追随して乾燥過程が進行するので、（１２Ｂ）および（１４Ｂ）に示すように、加熱手段の蒸気消費量を低減することが可能になっている。回転ドラム３に収容する１ロットの被乾燥物の重量を２００ｋｇとした場合、モップの場合、従来の段階式乾燥制御方式では、蒸気消費量２１０ｋｇ／ロットであるのに対し、本発明に係る乾燥条件自動追随型の乾燥方法では、蒸気消費量１７６ｋｇ／ロットになり、約１６％の蒸気消費量の削減が可能になった。回転ドラム３に収容する１ロットの被乾燥物の重量を２００ｋｇとした場合、マットの場合、従来の段階式乾燥制御方式では、蒸気消費量８３ｋｇ／ロットであるのに対し、本発明に係る乾燥条件自動追随型の乾燥方法では、蒸気消費量６６ｋｇ／ロットになり、約２０％の蒸気消費量の削減が可能になった。 The drying treatment of the mop product was carried out by setting the lower limit value α of the exhaust humidity as the target value to 20 g / m 3 . As shown in the exhaust humidity characteristic of (11A), after the introduction of the high temperature dry air is started, the exhaust humidity gradually increases from 10 g / m 3 at the start and decreases from the point where it exceeds 60 g / m 3 (drying). The target value (20 g / m 3 ) has been reached through the first stage), the second stage and the third stage of drying as the drying is promoted. The drying treatment of the mat product was carried out by setting the lower limit value α of the exhaust humidity of the target value to 15 g / m 3 . As shown in the exhaust humidity characteristic of (13A), after the introduction of the high temperature dry air is started, the exhaust humidity gradually increases from 10 g / m 3 at the start and decreases from the point where it exceeds 37 g / m 3 (drying). The target value (15 g / m 3 ) has been reached through the first stage), the second stage and the third stage of drying as the drying is promoted. As can be seen from FIGS. 11 to 14 from the drying treatment performed on the mop product and the mat product, as compared with the conventional stepwise drying control method shown in FIG. 15 under the monitoring of the drying treatment time, It can be seen that the circulation rate of the exhaust air and the fan rotation speed are finely executed in the case of the drying condition automatic follow-up type drying method according to the present invention, as compared with the conventional stepwise drying control method shown by the broken line. Since the drying process proceeds accurately following the change in humidity, it is possible to reduce the steam consumption of the heating means as shown in (12B) and (14B). When the weight of the object to be dried in one lot accommodated in the rotary drum 3 is 200 kg, in the case of the mop, the steam consumption is 210 kg / lot in the conventional stepwise drying control method, whereas the drying according to the present invention is performed. In the automatic condition-following drying method, the steam consumption is 176 kg / lot, and it is possible to reduce the steam consumption by about 16%. When the weight of the object to be dried in one lot accommodated in the rotary drum 3 is 200 kg, in the case of the mat, the steam consumption is 83 kg / lot in the conventional stepwise drying control method, whereas the drying according to the present invention is performed. In the automatic condition-following drying method, the steam consumption is 66 kg / lot, and it is possible to reduce the steam consumption by about 20%.
