The water is pushed to the water withdrawal pipe 26, and is ejected in the form of a fountain from each water sprinkling port 27, and is sprinkled onto the belt conveyor 4, thereby finishing and cleaning the green tea leaves if they are being moved there.
この時、水槽３の内側に位置する撒水口から撒水された
水は、そのまま水槽３内の水に混入し、水槽的洗浄用水
として利用される。つまり、仕上用の撒水の一部がその
まま荒洗い容器である水槽３へ補水として供給されるの
である。At this time, the water sprayed from the sprinkling port located inside the aquarium 3 mixes with the water in the aquarium 3 as it is and is used as water for cleaning the aquarium. In other words, a portion of the finishing water is directly supplied to the water tank 3, which is a rough washing container, as supplementary water.
一方、水槽３の外側へ突出したベルトコンベヤ部分で撒
水された水は、ネットベルトを通過等して下の落水回収
シュート２９から誘導シュート３０を経て濾過第１タン
ク３１へと集められる。On the other hand, the water sprayed by the belt conveyor portion projecting to the outside of the water tank 3 passes through a net belt, etc., and is collected into the first filtration tank 31 from the lower falling water collection chute 29 through the guiding chute 30.

濾過第２タンク３２では、前述のとおり自動給水器３７
によりタンク内の水位が一定となるべ（自動的に水道管
３６からも補給されるが、このように濾過第１タンク３
１よりオーバーフローしてくる水によっても補給される
。そして、ここでの水は、再び、撤水管２６へと供給さ
れていく。In the second filtration tank 32, the automatic water supply device 37 is installed as described above.
(The water level in the tank is automatically replenished from the water pipe 36, but in this way, the water level in the tank is kept constant.)
It is also replenished by water that overflows from 1. The water here is then supplied to the water withdrawal pipe 26 again.
したがって、この仕上木蓋用補水供給器系６によって、
一方では水槽３での洗浄水として、仕上げ用に既に消費
した水、しかもその中でも最も汚れている水が補給され
、その他の仕上げ用に消費した水はそのまま回収されて
濾過された後、再び仕上げ用の水として使用されるので
、水を効率的にしかも節水して使うことができる。Therefore, with this refill water supply system 6 for finished wooden lids,
On the other hand, the water already consumed for finishing, and the dirtiest among them, is replenished as washing water in tank 3, and the water consumed for other finishing is collected as is, filtered, and then used again for finishing. Since the water is used for other purposes, it is possible to use water efficiently and conserve water.
なお、撤水管２６は必ずしも必要としないが、どうせな
らこれを装備して、より清浄に洗浄した方が良い。Incidentally, although the water withdrawal pipe 26 is not necessarily required, it is better to have one anyway for cleaner cleaning.
また、本発明方法にあっては、節水することのみがその
要旨でないから、必ずしもこのように作用させる必要が
ないのも勿論である。Furthermore, since the purpose of the method of the present invention is not just to save water, it is of course not necessary to make it work in this way.

槽３内の水を攪拌する。The air pumped by the air pump 21 is guided to the air guide pipe 19 and ejected as bubbles from each of the jet ports 20 in the water, thereby stirring the water in the water tank 3.
この際、給葉機３８の送出端が臨まされた水路始端付近
の水は多くの噴気口によって特に激しく攪拌されている
。At this time, the water near the starting end of the waterway where the delivery end of the leaf feeder 38 faces is particularly vigorously agitated by the many blowholes.
一方、空気ポンプ２１より分岐した圧送空気はベルトコ
ンベヤ４先端転向部内の噴気管２３よりコンベヤベルト
を透気するよう強く吹きつけている。On the other hand, the compressed air branched from the air pump 21 is strongly blown through the blow pipe 23 in the tip turning section of the belt conveyor 4 so as to pass through the conveyor belt.
次に、茶生葉を水槽３に投下してから説水機３９に投下
されるまでの間、茶生葉が受ける作用を中心に説明する
。Next, the effects that the fresh tea leaves undergo during the period from when they are dropped into the water tank 3 until when they are dropped into the water heater 39 will be mainly explained.
給葉機３８から水槽３に投下された茶生葉は、直下水面
に着水するやいなや、水中に没し、浮上沈降を繰り返す
。The green tea leaves dropped into the water tank 3 from the leaf feeder 38 are submerged in the water as soon as they land directly below the water surface, and repeatedly float and sink.
普通、ただ茶生葉を水面に投下しただけでは茶生葉は浮
いてしまう。また、攪拌が弱くても給葉機の投入能力に
追いつかず、浮いたままの茶生葉が徐々に蓄積してくる
ため、投下する付近では気泡による攪拌を特に激しくし
ておくのが良い。Normally, if you just drop green tea leaves on the water surface, they will float. Furthermore, even if the agitation is weak, it will not be able to keep up with the feeding capacity of the leaf feeder, and the floating green tea leaves will gradually accumulate, so it is better to make the agitation by air bubbles particularly vigorous near the area where the tea leaves are to be dropped.
気泡により攪拌されている茶生葉は、本実施例の場合は

士の接触や、水や気泡との衝接で洗い落とされる。In this embodiment, the green tea leaves that are being stirred by the air bubbles are driven downstream by the water flow, repeating up-and-down movement in the water by the water flow driven by the screw 17. Sand and mud adhering to fresh tea leaves are washed away by contact between fresh tea leaves and collision with water and air bubbles.

ルトコンベヤ４により水槽３水中外へと掬い出される。The green tea leaves that have reached the downstream are directed by the water current to the part of the belt conveyor 4 that is floating above the water, and when the part that is submerged in the water comes into contact with the conveyor belt, the belt conveyor 4 moves the green tea leaves to the water tank 3. It is scooped out of the water.

とされる。When the green tea leaves that are not completely dropped at the tip of the belt conveyor 4 and remain attached to the conveyor belt reach the return surface of the conveyor, they are blown away by the pressure from the fumarole pipe 23 into the #RA39 dehydration tank, and are transferred to the net conveyor. The belt itself is also considered clean.

の工夫をした方が水路終端での茶生葉の詰まりかない。Note that the leaf feeder 38 and the dehydrator 39 installed before and after the cleaning device 1 may be conventional devices that have been widely known. There is no need to make any special efforts, but if it is a batch type, it is better to use something like a pool or to drive the screw 17 of the cleaning device 1 and the belt conveyor 4 intermittently. No clogging of green tea leaves at the end of the waterway.

。That is, the batch type dehydrator is, for example, disclosed in Japanese Patent Application Laid-Open No. 55-58
As seen in Publication No. 061, after the dehydration tank is rotated at high speed with the fresh tea leaves placed in the container or the container is placed in the container, the tank is turned over and the dehydrated fresh tea leaves inside are taken out and returned to its original state. Return to position and repeat the process of preparing for the next dehydration. Therefore, while the dewatering tank is inverted, green tea leaves cannot be dropped from the belt conveyor 4.
しかし、この間も水槽３内に水流が起きていると、茶生
葉はどんどん水路終端に集まり、やがて、ベルトコンベ
ヤ４の始端あたりが詰まってしまう。However, if the water flow continues in the water tank 3 during this time, green tea leaves will gradually gather at the end of the water channel, and eventually the starting end of the belt conveyor 4 will become clogged.

せるようにする。Therefore, when the dewatering tank is turned upside down and cannot receive green tea leaves, the driving of the belt conveyor 4 and screw 17 is stopped, and the green tea leaves being washed in the water tank 3 remain at the current position without being flown. While leaving the leaf feeder 3
The fresh tea leaves newly dropped from 8 were allowed to spread naturally due to the stirring action of air bubbles, etc., and the dehydration tank returned to its original position, making it possible to receive the fresh tea leaves. By the way, the belt conveyor 4 and the screw 17 are driven.
そうすれば、前述のとおり水流が再び起き、下流に至っ
た茶生葉は速やかにベルトコンベヤ４で掬°い上げられ
てい（。 詰まりもない。Then, as mentioned above, the water flow will start again, and the green tea leaves that have reached the downstream will be quickly scooped up by the belt conveyor 4 (there will be no clogging).

設ける。If the device is one in which operations such as reversing and returning the dehydration tank are performed automatically, a drive signal is issued to the belt conveyor 4 and the screw 17 only when the dehydration tank is capable of receiving green tea leaves. , it is necessary to be able to control the drive and stop in synchronization with the dehydrator 39 so that a stop signal is issued when the receiver cannot be inserted due to reversal, etc. Also, operations such as reversing and returning the dehydrator must be done manually. In the case of things that are done on purpose,
A switch is provided that can control the drive and stop of the belt conveyor 4 and the screw 17 individually or in conjunction with each other.
このように、ベルトコンベヤ４およびスクリュー１７を
間欠的に駆動すれば、前記のとおり水路終端での茶生葉
の詰まりが解消されるばかりでなく、茶生葉が洗浄作用
を受けている時間を長く確保することもできる。In this way, by intermittently driving the belt conveyor 4 and the screw 17, not only can the clogging of green tea leaves at the end of the waterway be eliminated as described above, but also the time during which the green tea leaves are exposed to the cleaning action can be ensured for a long time. You can also.
