以下、本発明の実施形態について図面を参照しながら具体的に説明する。
本実施形態に係るエア洗浄装置は、製茶工程に投入するための生葉に対して空気を吐出し、当該生葉に付着した付着物を除去することによりエア洗浄可能なものであり、図１に示すように、製茶工程Ｓ２より前工程の洗浄工程Ｓ１に設置されたものである。洗浄工程Ｓ１には、前工程のエア洗浄装置１と、後工程の水洗浄装置２とが設置されており、これらエア洗浄装置１によるエア洗浄及び水洗浄装置２による水洗いを経た生葉が製茶工程Ｓ２に搬出され、所定の製茶がなされるようになっている。 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The air cleaning apparatus according to the present embodiment is capable of air cleaning by discharging air to fresh leaves to be put into the tea making process and removing the deposits attached to the fresh leaves, as shown in FIG. As described above, it is installed in the washing step S1 which is a step before the tea making step S2. In the cleaning step S1, an air cleaning device 1 in a pre-process and a water cleaning device 2 in a post-process are installed, and fresh leaves that have undergone air cleaning by the air cleaning device 1 and water cleaning by the water cleaning device 2 are tea-making processes. It is carried out to S2, and predetermined tea making is made.

本実施形態に係る水洗浄装置２は、生葉を水洗いして製茶工程に投入するためのものであり、図４に示すように、洗浄槽Ａと、シャワードラムＢと、濾過槽Ｃとを有して構成されている。洗浄槽Ａは、シュートｂ３から投入された生葉を洗浄する水槽であり、掻き送りで生葉を水中に沈め、リングブローで多数の泡を発生させて洗浄するためのものである。シャワードラムＢは、掻き上げバケットにより洗浄槽Ａから生葉をすくい、回転しながら洗浄シャワーで多量の水を吐出して水洗いするためのものである。濾過槽Ｃは、洗浄槽Ａ及びシャワードラムＢで使用した水を濾過させる濾過フィルタを具備し、当該濾過フィルタで濾過された水をポンプで循環させて再利用するためのものである。   The water washing apparatus 2 according to the present embodiment is for washing fresh leaves with water and putting them into a tea making process, and has a washing tank A, a shower drum B, and a filtration tank C as shown in FIG. Configured. The washing tank A is a water tank for washing the fresh leaves introduced from the chute b3. The washing tank A is for sinking the fresh leaves in the water by scraping and generating a large number of bubbles by ring blow for washing. The shower drum B is for scooping fresh leaves from the washing tank A with a scraping bucket, and discharging a large amount of water in the washing shower while rotating to wash it. The filter tank C is provided with a filter for filtering water used in the washing tank A and the shower drum B, and the water filtered by the filter is circulated with a pump for reuse.

エア洗浄装置１は、上記水洗浄装置２より前工程に設置され、当該水洗浄装置２に対してエア洗浄後の生葉を搬出するものであり、図２〜４に示すように、網胴３と、エア供給手段４と、エア吸引手段５と、付着物受け手段６とから主に構成されている。尚、図４で示すように、コンベアａで搬送された生葉は、正転及び逆転可能なコンベアｂに至るよう構成されており、当該コンベアｂは、エア洗浄装置１によるエア洗浄が必要なときはシュートｂ２から生葉を落下させるよう正転駆動し、エア洗浄手段１によるエア洗浄が不要なときはシュートｂ１から生葉を落下させるよう逆転駆動するようになっている。   The air cleaning device 1 is installed in a process preceding the water cleaning device 2 and carries out fresh leaves after air cleaning to the water cleaning device 2. As shown in FIGS. The air supply means 4, the air suction means 5, and the deposit receiving means 6 are mainly configured. In addition, as shown in FIG. 4, the raw leaf conveyed by the conveyor a is comprised so that the forward rotation and reverse rotation of the conveyor b are possible, and the said conveyor b is when the air cleaning by the air cleaning apparatus 1 is required. Is driven to rotate forward so that the fresh leaves are dropped from the chute b2, and is driven to rotate backward so that the fresh leaves are dropped from the chute b1 when air cleaning by the air cleaning means 1 is unnecessary.

而して、シュートｂ２から落下した生葉は、エア洗浄手段１の網胴３における一端（図中右端）に投入されてエア洗浄装置１によるエア洗浄が施される一方、シュートｂ１から落下した生葉は、エア洗浄手段１には投入されず、後工程である水洗浄装置２の洗浄槽Ａに直接投入されることとなる。これにより、エア洗浄手段１によるエア洗浄が必要なときと不要なときとで選択的に洗浄を行わせることができる。   Thus, the fresh leaves dropped from the chute b2 are thrown into one end (right end in the figure) of the net barrel 3 of the air cleaning means 1 and subjected to air cleaning by the air cleaning device 1, while the fresh leaves dropped from the chute b1. Is not charged into the air cleaning means 1 but directly into the cleaning tank A of the water cleaning device 2 which is a subsequent process. Thereby, it is possible to selectively perform cleaning when air cleaning by the air cleaning means 1 is necessary and when it is not necessary.

網胴３は、一端（図３及び図４の右端）からエア洗浄前の生葉を投入可能とされるとともに他端（同図の左端）からエア洗浄後の生葉を搬出可能とされ、回転軸を中心として所定方向（図２中矢印方向）に回転可能な円筒状網体から成るものである。かかる網胴３は、その内部に生葉を収容可能な収容空間Ｓが形成されるとともに、生葉に付着した付着物である灰や砂等が通過し得る網目の金網で構成されている。尚、網胴３の中心軸は、回転中心を意味するものであり、何らの回転軸部材もない状態である。   The net body 3 can be fed with fresh leaves before air washing from one end (the right end in FIGS. 3 and 4) and can carry out fresh leaves after air washing from the other end (the left end in the figure). Is a cylindrical net that can rotate in a predetermined direction (in the direction of the arrow in FIG. 2). The net body 3 is formed with a mesh wire mesh in which an accommodation space S capable of accommodating fresh leaves is formed, and ash, sand, and the like, which are attached to the fresh leaves, can pass through. The central axis of the net body 3 means the center of rotation, and there is no rotating shaft member.

また、網胴３は、金属製のフレームＦに回転可能に支持されるものとされており、一端から他端に向かって所定角度下方に傾斜して配設されている。尚、図中符号Ｒ１、Ｒ２は、網胴３を回転可能に支持するローラを示しており、これらローラＲ１、Ｒ２を回転駆動させるモータＭが配設されている。かかるモータＭは、生葉のエア洗浄中は常時駆動されるものとされている。   The net body 3 is rotatably supported by a metal frame F, and is disposed so as to be inclined downward by a predetermined angle from one end to the other end. Reference numerals R1 and R2 in the figure indicate rollers that rotatably support the net barrel 3, and a motor M that rotationally drives these rollers R1 and R2 is provided. The motor M is always driven during fresh leaf air cleaning.

ここで、本実施形態においては、網胴３の内壁面３ａに桟３ｂ（図３参照）が形成されている。この桟３ｂは、網胴３の内壁面３ａにおいて一体的に突出形成されたもので、これにより、網胴３内の生葉を撹拌しつつ一端から他端まで搬送可能となっている。即ち、網胴３内に投入された生葉は、当該網胴３の傾斜構造及び桟３ｂの作用によって一端から他端に搬送されるとともに、桟３ｂの作用によって収容空間Ｓの径方向において上方に向かって掻き上げられ、撹拌可能とされているのである。   Here, in the present embodiment, a crosspiece 3b (see FIG. 3) is formed on the inner wall surface 3a of the net barrel 3. The crosspiece 3b is integrally formed on the inner wall surface 3a of the net barrel 3 so that it can be conveyed from one end to the other end while stirring the fresh leaves in the net barrel 3. That is, the fresh leaves thrown into the net body 3 are transported from one end to the other end by the action of the inclined structure of the net body 3 and the crosspiece 3b, and upward in the radial direction of the accommodation space S by the action of the crosspiece 3b. It is scraped up and can be stirred.

エア供給手段４は、網胴３内に空気を吐出可能なもので、吐出ブロア４ａと、吹出ダクト４ｂと、該吹出ダクト４ｂの先端で開口して成る吐出口４ｃとから主に構成されている。然るに、吐出ブロア４ａを駆動させると、生じた送風が吹出ダクト４ｂを通って吐出口４ｃから吐出されるようになっている。吐出口４ｃは、網胴３の側面から内部に向かって開口されており、これにより網胴３内に吐出ブロア４ａで生じた空気を吐出可能とされている。   The air supply means 4 is capable of discharging air into the net body 3, and is mainly composed of a discharge blower 4a, a discharge duct 4b, and a discharge port 4c that is opened at the tip of the discharge duct 4b. Yes. However, when the discharge blower 4a is driven, the generated air is discharged from the discharge port 4c through the blowout duct 4b. The discharge port 4 c is opened from the side surface of the net cylinder 3 toward the inside, and thereby, air generated by the discharge blower 4 a can be discharged into the net cylinder 3.

エア吸引手段５は、網胴３内から空気を吸引可能なもので、吸引ブロア５ａと、吸引ダクト５ｂと、該吸引ダクト５ｂの先端で開口して成る吸引口５ｃとから主に構成されている。然るに、吸引ブロア５ａを駆動させると、生じた負圧によって網胴３内の空気が吸引され、吸引ダクト５ｂを通って外部に排出されるようになっている。吸引口５ｃは、網胴３の側面から内部に向かって開口されており、これにより網胴３内の空気を外部に排出可能とされている。   The air suction means 5 is capable of sucking air from the inside of the net body 3, and is mainly composed of a suction blower 5a, a suction duct 5b, and a suction port 5c opened at the tip of the suction duct 5b. Yes. However, when the suction blower 5a is driven, the air in the net body 3 is sucked by the generated negative pressure and discharged to the outside through the suction duct 5b. The suction port 5c is opened from the side surface of the net cylinder 3 toward the inside thereof, whereby the air in the net cylinder 3 can be discharged to the outside.

而して、網胴３の一端から投入された生葉は、その他端に向かって搬送される過程において、桟３ｂによって上方に掻き上げられて撹拌されるとともに、エア供給手段４の吐出口４ｃから吐出された空気によってエア洗浄され、表面に付着した灰や砂等の付着物が吹き飛ばされるとともに、その吹き飛ばされた付着物が吸引口５ｃから吸引されるよう構成されている。尚、網胴３は、その網目が専ら付着物を通過させるよう設定されたものの他、混在する切れ葉（くず葉）を通過させる網目としてもよい。   Thus, the fresh leaves thrown in from one end of the net barrel 3 are stirred up and stirred by the crosspiece 3b in the process of being conveyed toward the other end, and from the discharge port 4c of the air supply means 4. Air is washed with the discharged air, and deposits such as ash and sand adhering to the surface are blown away, and the blown deposits are sucked from the suction port 5c. In addition, the net body 3 may be a mesh that allows a cut leaf (crumb leaf) to be mixed in addition to a mesh that is set so that the mesh passes exclusively.

また、本実施形態においては、図４に示すように、網胴３の下方の位置に付着物受け手段６が配設されている。かかる付着物受け手段６は、生葉から除去されて落下した付着物を受け得るもので、例えば汎用的な搬送手段等で構成されたものである。これにより、軽い付着物（灰など）がエア吸引手段５で吸引されるとともに重い付着物（砂など）が当該付着物受け手段６で受けられるようになっている。   Further, in the present embodiment, as shown in FIG. 4, the deposit receiving means 6 is disposed at a position below the net barrel 3. The attached matter receiving means 6 can receive attached matter that has been removed from the raw leaves and has fallen, and is constituted by, for example, a general-purpose transport means. Thereby, a light deposit (such as ash) is sucked by the air suction means 5 and a heavy deposit (such as sand) is received by the deposit receiving means 6.

これにより、軽い付着物がエア吸引手段５で吸引されるとともに重い付着物が付着物受け手段６で受けられるので、生葉から除去した付着物を選別しつつより確実に収集することができ、その後の廃棄作業をより効率的に行わせることができる。尚、本実施形態によれば、生葉に付着した毛茸（新葉の裏側に分布し、そのほとんどは葉の発育とともに自然と脱落するものであって、脱落せず残存したもの）をエア吐出手段４の吐出口４ｃから吐出された空気で吹き飛ばしてエア吸引手段５の吸引口５ｃで吸引させることができる。   As a result, since light deposits are sucked by the air suction means 5 and heavy deposits are received by the deposit receiving means 6, the deposits removed from the raw leaves can be collected more reliably and then collected. This makes it possible to perform the disposal work more efficiently. In addition, according to the present embodiment, hair flies adhering to fresh leaves (distributed on the back side of new leaves, most of which naturally fall off with the growth of the leaves and remain without dropping) are discharged by air. The air discharged from the discharge port 4 c of the means 4 can be blown off and sucked by the suction port 5 c of the air suction means 5.

ここで、本実施形態においては、エア供給手段４の空気の吐出口４ｃとエア吸引手段５の空気の吸引口５ｃとが網胴３を介して対向して配設されている。即ち、エア供給手段４の空気の吐出口４ｃとエア吸引手段５の空気の吸引口５ｃとは、それぞれ網胴３の側面に向かって配設されており、これら吐出口４ｃと吸引口５ｃとが対向する如く形成されているのである。これにより、吐出口４ｃから吐出された空気で生葉から付着物を吹き飛ばして除去し得るとともに、その除去された付着物を吸引口５ｃで吸引させることができ、吹き飛ばされた付着物が周囲に飛散してしまうのを抑制することができる。   Here, in the present embodiment, the air discharge port 4 c of the air supply unit 4 and the air suction port 5 c of the air suction unit 5 are disposed to face each other with the net body 3 interposed therebetween. That is, the air discharge port 4c of the air supply means 4 and the air suction port 5c of the air suction means 5 are respectively arranged toward the side surface of the net body 3, and these discharge ports 4c, suction ports 5c, Are formed so as to face each other. As a result, the deposits can be removed by blowing away the fresh leaves with the air discharged from the discharge port 4c, and the removed deposits can be sucked by the suction port 5c. Can be suppressed.

また、エア供給手段４の空気の吐出口４ｃ及びエア吸引手段５の空気の吸引口５ｃは、それぞれ網胴３の回転軸近傍に向かって開口（即ち、網胴３の収容空間の中心近傍に向かって開口）しており、桟３ｂにて上方に掻き上げられた生葉に対し、吐出口４ｃからの空気が当たるよう設定されている。これにより、より確実且つスムーズに、吐出口４ｃから吐出された空気で生葉から付着物を吹き飛ばして除去し得るとともに、吐出口４ｃからの空気で生葉に対する撹拌作用を図ることができる。   The air discharge port 4c of the air supply means 4 and the air suction port 5c of the air suction means 5 are opened toward the vicinity of the rotation axis of the net cylinder 3 (that is, near the center of the accommodation space of the net cylinder 3). It is set so that air from the discharge port 4c hits the fresh leaves scraped upward by the crosspiece 3b. As a result, the deposits can be removed and blown away from the raw leaves with air discharged from the discharge port 4c more reliably and smoothly, and the air can be stirred with the air from the discharge port 4c.

更に、本実施形態においては、エア供給手段４の空気の吐出口４ｃ及びエア吸引手段５の空気の吸引口５ｃは、網胴３の回転軸方向に沿って延設されている。より具体的には、図５に示すように、エア供給手段４の空気の吐出口４ｃは、網胴３の一方の側面において当該網胴３の回転軸方向（同図（ｂ）の左右方向）に長く開口しているとともに、図６に示すように、エア吸引手段５の空気の吸引口５ｃは、網胴３の他方の側面において当該網胴３の回転軸方向（同図（ａ）の左右方向）に長く開口している。   Further, in the present embodiment, the air discharge port 4 c of the air supply unit 4 and the air suction port 5 c of the air suction unit 5 are extended along the rotational axis direction of the net body 3. More specifically, as shown in FIG. 5, the air discharge port 4 c of the air supply means 4 is arranged on one side surface of the net cylinder 3 in the direction of the axis of rotation of the net cylinder 3 (the left-right direction in FIG. 5B). 6), and the air suction port 5c of the air suction means 5 is located on the other side surface of the net cylinder 3 in the direction of the axis of rotation of the net cylinder 3 (FIG. 6 (a)).
