Description

本発明は、皿状容器を等間隔に運搬しながら、前記各容器内で米飯を煮炊きするための方法及び装置に関する。 The present invention relates to a method and apparatus for boiling cooked rice in each container while conveying the dish-shaped container at equal intervals.

洗米と該洗米を炊き上げるのに適する量の水とを皿状容器に収容したあと、前記皿状容器に被せたカバーフイルムと同皿状容器開口部周縁の鍔部分との間を、蒸気噴出用の通路を残すようにシールして多数の包装体を形成し、当該各包装体をコンベヤによって蒸気釜に搬入して炊飯する装置は公知として、下記の特許文献に開示されている。   After storing the washed rice and an amount of water suitable for cooking the washed rice in a dish-shaped container, steam is blown between the cover film placed on the dish-shaped container and the ridge part at the periphery of the dish-shaped container opening. An apparatus for forming a large number of packages by sealing them so as to leave a passage for the purpose, and carrying each rice package into a steamer by a conveyor and cooking rice is disclosed in the following patent documents.

前記装置における蒸気釜は、前記包装体をコンベヤにより搬入、搬出する関係上、前記搬入口及び搬出口が開口しており、必然、この両開口部からは蒸気が漏れ出るので、蒸気圧があがりにくく、同時に温度むらが生ずるので、前記包装体内の米飯に炊きむらが生ずるという問題がある。
特開平7−155121号公報 特開2002−176938号公報
In the steam pot in the apparatus, the carry-in port and the carry-out port are open because the package is carried in and out by a conveyor, and the vapor leaks from both openings, so the vapor pressure rises. It is difficult to cause temperature unevenness at the same time, and there is a problem that uneven cooking occurs in the cooked rice in the package.
JP 7-155121 A JP 2002-176938 A

本発明は、ふっくらとむらのない米飯を炊き上げるために、熱水を摂氏80度以下に低下させないように加熱し且つ貯溜するタンク内の一端から同他端に向けて設けたベルトコンベヤと、洗米と該洗米を炊き上げるのに適する量の水とを皿状容器に収容し且つ前記皿状容器に被せたカバーフイルムと同皿状容器開口部周縁の鍔部分との間を、蒸気噴出用の流動抵抗通路を残すようにシールした包装体を前記コンベヤにより運搬し、該コンベヤの運搬軌道の大部分において前記包装体を、内部の洗米が殆ど炊き上がるまで前記熱水中を潜水運搬する手段と、前記タンクから搬出する前記包装体における流動抵抗通路を完全密封する手段とにより構成する。   The present invention is a belt conveyor provided from one end to the other end in a tank that heats and stores hot water so that it does not decrease below 80 degrees Celsius in order to cook plump and even rice. For steam jetting between the washing film and the cover film covered with the dish-shaped container and the ridge part at the periphery of the dish-shaped container opening, containing a quantity of water suitable for cooking the washed rice in a dish-shaped container Means for transporting the package sealed by the conveyor so as to leave a flow resistance passage, and diving and transporting the heated body in the hot water until most of the washed rice is cooked in most of the conveyor track of the conveyor. And means for completely sealing the flow resistance passage in the package carried out from the tank.

一般にトレイと称する開口縁に連続的に鍔を備える皿状の容器は、それを成型する合成樹脂などの材料があまり薄くては形をなさず、一方前記容器開口部を密封するカバーフイルムは経済的な面でミクロ単位の薄いものを使用するのが一般的であるから、かかる皿状容器に被せたカバーフイルムと同皿状容器開口部周縁の鍔部分との間を、蒸気噴出用の通路を残すように溶着してシールした場合、前記カバーフイルムは、厚みのある皿状容器の鍔部分に張り付いて流動抵抗のある通路部分を形成する。つまり、例えばプラステイック製の包袋の袋口を溶着シールし、該シール部分に幅狭い通路を形成しても、包袋の袋口は形成材料そのものが軟質で変形しやすく、従って同袋口も包袋の変形によつて容易に開口するのに比べ、前記皿状容器の鍔部分の通路は、同容器内外に一定値以上の圧力差が発生しない間は液類の自然流通を阻止する剛性構造になる。   In general, a dish-like container that has a ridge continuously at the opening edge, called a tray, does not form if the material such as synthetic resin is too thin, and the cover film that seals the container opening is economical. Since it is common to use a thin unit of micro units in general, a passage for steam ejection is provided between the cover film placed on the dish-shaped container and the ridge part at the periphery of the opening of the dish-shaped container. When the film is welded and sealed so as to leave a film, the cover film sticks to the ridge portion of the thick dish-like container to form a passage portion having flow resistance. That is, for example, even if the bag mouth of a plastic bag is welded and sealed and a narrow passage is formed in the seal portion, the bag mouth of the bag is soft and easily deformed. Compared to the easy opening due to the deformation of the sachet, the passage in the bowl portion of the dish-like container has a rigidity that prevents the natural circulation of liquids while a pressure difference of a certain value or more does not occur inside and outside the container. Become a structure.

そこで、洗米と該洗米を炊き上げるのに適する量の水とを収容する前記のごとき包装体は、熱水を摂氏80度以下に低下させないように貯溜するタンクの一端からベルトコンベヤにより、先ず潜水搬入する。この場合、容器の周囲に熱水の重量が作用することになるが、容器シール部の前記通路は、鍔に対するカバーフイルムの張り付きにより皿状容器からの空気の排出はおろか、外からの熱水の侵入をも許容しない。つまり鍔とカバーフイルムとが張り付くミクロな隙間の前記通路においては、容器及びカバーフイルムを形成する材料の撥水効果は外部からの液の侵入を阻止するのである。   Therefore, the packaging body containing the washing rice and an amount of water suitable for cooking the washed rice is first submerged by a belt conveyor from one end of a tank for storing hot water so as not to drop below 80 degrees Celsius. Carry in. In this case, the weight of hot water acts on the periphery of the container. However, the passage of the container seal portion is not limited to discharging air from the dish-like container due to sticking of the cover film to the bag, or hot water from the outside. Intrusion is not allowed. In other words, in the passage having a micro gap between the ridge and the cover film, the water repellent effect of the material forming the container and the cover film prevents the liquid from entering from the outside.

その後の運搬中、前記の熱水エネルギーにより皿状容器内の水の蒸気圧が高まると、同蒸気は圧力差により、前記の流動抵抗値のある通路を強制的に押し開いて熱水中に噴出を開始し、同時に洗米を加熱する。この場合、前記通路の流動抵抗は皿状容器内での激しい沸騰を抑制し勝ちであるから、米の炊き汁の通路からの漏出を押さえ、主に蒸気のみを噴出して米を米飯化する。   During the subsequent transportation, when the vapor pressure of the water in the dish-like container is increased by the hot water energy, the vapor is forced to open the passage with the flow resistance value due to the pressure difference and into the hot water. Blowing is started and the washed rice is heated at the same time. In this case, since the flow resistance of the passage tends to suppress intense boiling in the dish-like container, the leakage of the rice cooking juice from the passage is suppressed, and only the steam is mainly ejected to turn the rice into rice. .

熱水に潜水する容器内の米は、煮炊き、後蒸しとも、上下左右の熱水からほぼ均等な熱を受けてむらなく炊き上がる。この場合、通路から蒸気を常時噴出させるので、圧力釜のように高圧、高熱化せずに、米飯を芯のある状態に炊き上げる。   Rice in a container that is submerged in hot water is boiled and cooked evenly after receiving steam from the top, bottom, left and right hot water. In this case, since steam is always ejected from the passage, the cooked rice is cooked in a cored state without increasing the pressure and heat as in a pressure cooker.


コンベヤシステムによる米の炊飯において、熱水のエネルギーを皿状容器の全周から常時、熱むらなく内部に伝えるようにしたことで、ふっくらとして炊きむらのない小売用米飯パックを形成する目的を達成した。

In cooking rice with a conveyor system, the energy of hot water is always transmitted from the entire circumference of the dish-shaped container to the inside without heat, thereby achieving the purpose of forming a retail rice pack that does not cook evenly as a plump. did.

図2に示すように、先ず、上部開口縁周囲に連続的な鍔11を連設した皿状容器10、つまりプラステイック製或いはアルミニュームラミネート製のトレイに、洗米12と、前記米を炊き上げるのに適応な量の水13とを収容したあと、前記鍔11を枠型のシール台14に搭載し、また同皿状容器の上にカバーフイルム15を配置する一方、パイプヒータ16を内部に設置した枠型シーラ17により、前記鍔11全域に、前記のカバーフイルム15を溶着して包装体を形成する。この場合、前記水13の上面と、カバーフイルム15との間のヘッドスペース19は、前記水13の沸騰に適応できるような容積に設定することが望まれる。   As shown in FIG. 2, first, the washed rice 12 and the rice are cooked in a dish-like container 10 in which a continuous bowl 11 is continuously provided around the upper opening edge, that is, a tray made of plastic or aluminum laminate. After accommodating a suitable amount of water 13, the bottle 11 is mounted on a frame-shaped seal base 14, and a cover film 15 is disposed on the same dish-like container, while a pipe heater 16 is installed inside. With the frame type sealer 17, the cover film 15 is welded over the entire area of the ridge 11 to form a package. In this case, it is desirable that the head space 19 between the upper surface of the water 13 and the cover film 15 is set to a volume that can adapt to the boiling of the water 13.

前記の枠型シーラ17は、図3のように鍔11とカバーフイルム15とを、皿状容器10を取り囲む少なくとも大小2重巻きのシール線21、22により溶着する。この場合、シール線21に形成する第1出口23と、シール線22に形成する第2出口24とを、前記両シール線の間の細長き通路25を介して迷路状態に開口するのが望ましい。つまり前記通路25は、その長さの和が大きいほど流動抵抗値が大きくなるから、例えば両出口23b、24bの間にシール線21bの一部を食い込ませ、より流動抵抗の大きい通路26を形成できる。ただ前記通路25の幅を必要以上に大きくすると熱水逆流の可能性が大きくなるので、その上限数値と、しかしあまり小さいと蒸気噴出を妨害することになるので、その下限数値とを下記実施データのように設定する。すなわち同上限幅は8ミリメートルでこの場合、熱水逆流を防ぐ通路長さは30ミリメートル以上、また同下限幅は2ミリメートルでこの場合、容易な蒸気噴出確保のために通路長さは10ミリメートル以下である。   As shown in FIG. 3, the frame-type sealer 17 welds the ridge 11 and the cover film 15 with at least double-wrapped seal lines 21 and 22 that surround the dish-like container 10. In this case, it is desirable that the first outlet 23 formed in the seal line 21 and the second outlet 24 formed in the seal line 22 are opened in a labyrinth state via an elongated passage 25 between the two seal lines. . That is, the flow resistance value of the passage 25 increases as the sum of its lengths increases. For example, a part of the seal line 21b is bitten between the outlets 23b and 24b to form the passage 26 having a higher flow resistance. it can. However, if the width of the passage 25 is increased more than necessary, the possibility of hot water backflow increases. Therefore, if it is too small, steam ejection will be hindered. Set as follows. In other words, the upper limit width is 8 millimeters, and in this case, the passage length for preventing backflow of hot water is 30 millimeters or more, and the lower limit width is 2 millimeters. In this case, the passage length is 10 millimeters or less to ensure easy steam ejection. It is.

図4に示すごとく鍔11にカバーフイルム15を溶着する場合、シール枠17の下面に形成する2本のエッジ18は、熱によって前記鍔11に2本の溝27を彫り込むようにカバーフイルム15を溶着する結果、前記両溝27の間で、分厚く剛性のある鍔11に対して薄いカバーフイルム15は張り付き、その間の隙間に流動抵抗を形成するのである。   As shown in FIG. 4, when the cover film 15 is welded to the flange 11, the two edges 18 formed on the lower surface of the seal frame 17 are covered with the cover film 15 so that the two grooves 27 are carved into the flange 11 by heat. As a result, the thin cover film 15 sticks to the thick and rigid ridge 11 between the grooves 27, and a flow resistance is formed in the gap therebetween.

一方熱水タンクは、図5に示すような横方向細長い上面開口型のタンク30と、前記タンク30の開口面に被さる蓋板31と、一部を前記タンク30内に配置するベルトコンベヤ32と、前記コンベヤ32の上域を並走する押さえベルト33とにより構成する。   On the other hand, the hot water tank is composed of a horizontally elongated upper surface opening type tank 30 as shown in FIG. 5, a lid plate 31 covering the opening surface of the tank 30, and a belt conveyor 32 partially disposed in the tank 30. , And a pressing belt 33 that runs in parallel on the upper region of the conveyor 32.

図6のように前記のベルトコンベヤ32を、両側のエンドレスチェン35と、これら両チェン35の間を繋ぐ多数の並列バー36とにより構成する。この場合、皿状容器10は形が一定であるから、4本の各バー36は皿状容器の鍔11を下から支え、図7、8に示すごとく特に内側2本のバー36bは、皿状容器10の横方向への移動を阻止するのに適するように曲げ加工を施す。   As shown in FIG. 6, the belt conveyor 32 is constituted by endless chains 35 on both sides and a large number of parallel bars 36 connecting the chains 35. In this case, since the shape of the dish-like container 10 is constant, each of the four bars 36 supports the bowl 11 of the dish-like container from the bottom, and as shown in FIGS. Bending is performed so as to be suitable for preventing the lateral movement of the container 10.

なお前記のベルトコンベヤ32の別個な例として、図9に示すように、両側のエンドレスチェン37の間を繋ぐ並列バー38を、上下2枚のゴム製シート39、40で挟持して構成し、該シートの上面に、各皿状容器10の底部分を位置決めする可撓性の突起物41、42を等間隔に配置する。かかる構成においては皿状容器10に十分熱水が作用するように、前記シート39、40に多数の熱水の流通穴43を設置する。   In addition, as a separate example of the belt conveyor 32, as shown in FIG. 9, a parallel bar 38 connecting between the endless chains 37 on both sides is sandwiched between two upper and lower rubber sheets 39, 40, Flexible protrusions 41 and 42 for positioning the bottom portion of each dish-like container 10 are arranged at equal intervals on the upper surface of the sheet. In such a configuration, a large number of hot water circulation holes 43 are provided in the sheets 39 and 40 so that the hot water sufficiently acts on the dish-like container 10.

図10に拡大図示するように、前記タンク30の中に貯溜する熱水44に対して、ベルトコンベヤ32は各皿状包装体10を等間隔で搬入し、これら各包装体10の上からは押さえベルト33が順次負荷する。かかる負荷作用は、内部空気の浮力で包装体10が位置ずれするのを防ぐためで、この押さえベルトは、図6ないし図8に示すようなエンドレスチェン33で作られるが、エンドレス製の金属ネットを代用することも可能である。   As shown in an enlarged view in FIG. 10, the belt conveyor 32 carries the dish-shaped packaging bodies 10 at equal intervals with respect to the hot water 44 stored in the tank 30, and from above these packaging bodies 10. The holding belt 33 is sequentially loaded. This load action is to prevent the package 10 from being displaced due to the buoyancy of the internal air. This holding belt is made of an endless chain 33 as shown in FIGS. Can be substituted.

同じ図10においてタンク30の周囲に設置する断熱材45の断熱効果と、フイン付きのパイプ46からの放熱エネルギー効果とで、熱水の温度を一定に保持する。つまり時間当たりの包装体10の搬入量は定まり、熱水の温度損失量は計算できるので、前記パイプ46からの放出熱エネルギーにより熱水を、最高摂氏95度に保持する。なお前記パイプ46は、熱水44に高熱蒸気を直接放出するのが最も効果的であるというデータがあるので、かかる加熱手段を用いることがある。そして熱水が汚れないように、常に一定量の交換浄化は必要不可欠である。   In FIG. 10, the temperature of the hot water is kept constant by the heat insulating effect of the heat insulating material 45 installed around the tank 30 and the heat radiation energy effect from the finned pipe 46. That is, since the amount of the package 10 brought in per time is determined and the temperature loss amount of the hot water can be calculated, the hot water is held at a maximum of 95 degrees Celsius by the heat energy released from the pipe 46. Since the pipe 46 has the data that it is most effective to directly release the high-temperature steam to the hot water 44, such a heating means may be used. In order to prevent the hot water from becoming dirty, a certain amount of exchange and purification is always indispensable.

なお、図5のごとく両ベルト32、33をタンク30の外部に露出する量が大きいほど熱損失が大きいので、図11のように、これら両ベルト32、33の大部分を前記タンク30内で循環する方法を用いるように考慮する必要もある。かかる構成の場合は、エンドレスチェン51に等間隔に設置したアタッチメント52で、包装体10を、並行滑走バー53に沿って滑らせ且つ前記ベルトコンベヤ32に移乗させることになる。   As the amount of both the belts 32 and 33 exposed to the outside of the tank 30 increases as shown in FIG. 5, the heat loss increases. Therefore, most of the belts 32 and 33 are contained in the tank 30 as shown in FIG. It is also necessary to consider using a circulating method. In the case of such a configuration, the packaging body 10 is slid along the parallel running bar 53 and transferred to the belt conveyor 32 by the attachments 52 installed at equal intervals on the endless chain 51.

図1に示すように包装体10は一定時間、熱水44を潜水して移動するが、カバーフイルム15に作用する熱水の重量により内部空気を圧縮すると同時に、通路25を水圧が押す傾向になるので、第2出口24においては熱水の逆流入が阻止される。その間の熱交換により包装体10内部の水は次第に高温化し、時間経過とともに前記出口からの蒸気発生50が開始され、洗米が次第に米飯化する。   As shown in FIG. 1, the package 10 moves by submerging the hot water 44 for a certain period of time, but at the same time as compressing the internal air by the weight of the hot water acting on the cover film 15, the water pressure tends to push the passage 25. Therefore, the reverse inflow of hot water is prevented at the second outlet 24. During this time, the water inside the package 10 gradually becomes hot due to heat exchange, and steam generation 50 from the outlet is started with the passage of time, and the washed rice gradually becomes rice.

炊飯後半の蒸しだきも熱水が行うが、直火式に比べて炊飯物に焦げを作らず、ご飯のべとつきがなくなるまで蒸気噴出が続く。この場合圧力釜による加工のように、包装体の内部は高圧、高温化しないので、米粒は軟弱化しない。やがて包装体からの蒸気噴出が和らぎ、該噴出通路は水圧で塞ぎ傾向を保持するので、熱水逆流は阻止される。   Steaming in the latter half of the rice cooking is also done with hot water, but steaming continues until the rice is not sticky compared to the direct-fired type. In this case, the rice grains are not weakened because the inside of the package is not heated to a high pressure and temperature as in the case of processing with a pressure cooker. Eventually, the jet of steam from the package softens, and the jet passage retains its tendency to close with water pressure, so that hot water backflow is prevented.

前記のごとくタンク30の後域においては同タンク内の水圧が包装体の噴出通路を塞ぎ、圧力の落ちた包装体10からの蒸気噴出を押さえるので、前記タンク30から搬出した包装体10内に蓄えられる蒸気は、周囲の冷気環境でもってカバーフイルム15の内面に結露し、その後この露が滴り落ちた部分の飯米を変質させて米飯の味を低下させ場合がある。   As described above, in the rear region of the tank 30, the water pressure in the tank closes the ejection passage of the packaging body, and suppresses the ejection of steam from the packaging body 10 that has fallen in pressure. The stored steam may condense on the inner surface of the cover film 15 in the surrounding cool air environment, and then the rice that has been dripped down may be altered to lower the taste of the cooked rice.

そこで図14に示すように、タンク30の後部に気化庫90を設置し、加熱機91から前記気化庫90に乾燥熱エネルギーを送り同気化庫90内を摂氏75度前後に保ち、前記タンク30で加熱処理した包装体を搬入する前記気化庫90内の前記熱エネルギーで、前記包装体内の蒸気凝縮を防止しながら、同蒸気を気化して噴出通路から包装体外に排除し且つ同包装体を前記気化庫90からシール装置への搬出する。
Therefore, as shown in FIG. 14, a vaporizer 90 is installed at the rear of the tank 30, drying heat energy is sent from the heater 91 to the vaporizer 90, and the inside of the vaporizer 90 is maintained at around 75 degrees Celsius, so that the tank 30 The heat energy in the vaporizing chamber 90 for carrying the package heated in the above is vaporized by removing the vapor from the ejection passage and out of the package while preventing vapor condensation in the package. Unload from the vaporizer 90 to the sealing device.

図12に示すように、タンク30の終端においては、ベルトコンベヤ32が各包装体10を並行滑走バー60の上に押し出すので、搬出装置(図示省略)は前記包装体10を、枠型のシール台61に搬入する。レール63上において各シール台61、62は一定の時間間隔で断続移動するので、かかる移動のタイミングに合わせて前記の搬出装置は、各トレイ10をシール台61、62に搬入するのである。   As shown in FIG. 12, at the end of the tank 30, the belt conveyor 32 pushes each package 10 onto the parallel sliding bar 60. Therefore, the unloading device (not shown) removes the package 10 from the frame-shaped seal. Carry into the platform 61. Since the seal stands 61 and 62 move intermittently on the rail 63 at regular time intervals, the carry-out device carries the trays 10 into the seal stands 61 and 62 in accordance with the timing of such movement.

前記の各シール台61、62と一体移動する包装体10の未シール部分を、次工程は完全密封し、外部からの雑菌侵入を阻止して炊飯物の長期保存を可能にするのである。   The next process completely seals the unsealed portion of the package 10 that moves integrally with the sealing bases 61 and 62, and prevents the invasion of germs from the outside to enable long-term storage of the cooked rice.

前記の洗米は、赤飯とするために適当量の小豆を含む場合があるし、また麦のような穀類を含む場合もある。ただ、これら穀類の硬度は洗米のそれとは異なるので、事前に軟化のための処置を必要とする。   The washed rice may contain an appropriate amount of red beans to make red rice, or may contain grains such as wheat. However, since the hardness of these cereals is different from that of washed rice, treatment for softening is required in advance.

また前記洗米を炊きこみご飯として加工するために、肉あるいは野菜のような食材及び、塩分や調味材を、洗米及び水に加える場合がある。   In addition, in order to process the washed rice as cooked rice, ingredients such as meat or vegetables and salt or seasoning may be added to the washed rice and water.

図13に示す包装体の形成には、プラステイック帯状材70を長手方向に運搬しながら、第1セクションで同帯状材70を、ブリスター装置、つまり下型71と蓋板72とで挟圧しながら順次真空吸引力によって皿状容器10として成型したあと、第2セクションで主として洗米などの食材を、また第3セクションで水、調味液などをそれぞれ充填し、第4セクションにおいてカバーフイルム15を被せ、第5セクションでシール台74とシーラ75とで皿状容器10の鍔部分にカバーフイルム15を溶着する。この場合、図3のごとき通路23、24、25を形成すると共に、この通路を外部に開放するために、図13の矢印76部分、つまり各皿状容器10の間をカットして切れ目を形成する。 In order to form the package shown in FIG. 13, the plastic strip 70 is transported in the longitudinal direction, and the strip 70 is sequentially pressed between the blister device, that is, the lower mold 71 and the cover plate 72 in the first section. After forming as a dish-like container 10 by vacuum suction, the second section is filled mainly with foodstuffs such as washed rice, the third section is filled with water, seasoning liquid, etc., and the fourth section is covered with the cover film 15. The cover film 15 is welded to the ridge portion of the dish-like container 10 with the seal stand 74 and the sealer 75 in five sections. In this case, passages 23, 24, and 25 as shown in FIG. 3 are formed, and in order to open the passages to the outside, a cut is formed by cutting the portion of arrow 76 in FIG. To do.

前記の各包装体は蒸気抜き部分をカットしたが、その外の部分は未だに連結しているので、かかる状態のまま各連合包装体を一定時間、タンク30に搬入し、その後、二次シール台77と同シーラ78とで各包装体を完全密封すると同時に、シーラ78に設けた切断刃79により各包装体10を独立分離するのである。   Each of the packaging bodies has a cut-off part of the steam, but the other parts are still connected. Therefore, the associated packaging bodies are carried into the tank 30 for a certain period of time in such a state, and then the secondary sealing table. 77 and the sealer 78 completely seal each package, and at the same time, each package 10 is independently separated by a cutting blade 79 provided on the sealer 78.
