The fresh tea leaves A are stirred by the stirring tool 5, and the thickness on the net conveyor 1 is made uniform, and the raw tea leaves A are conveyed to the fresh tea processing chamber 6. In the fresh tea leaf processing chamber 6, hot water is ejected from the hot water outlet 8, and hot water of a predetermined temperature is sequentially applied to the fresh tea leaves A. At this time, the time for which hot water is applied to the fresh tea leaves A is adjusted by changing the speed of the net conveyor 1. After the hot water hits the fresh tea leaves A, it falls to the hot water collecting plate 45, and is collected and drained to the collection box 19 and drained. When the hot water treatment is completed, the fresh tea leaves A are transported to the fresh tea leaf outlet section 12 and water at room temperature is blown out from the water outlet 10 sequentially to the fresh tea leaves A that have been treated with hot water, and the temperature of the fresh tea leaves A is suddenly brought to near room temperature. Allow to cool. The fresh tea leaves A further transported from the fresh tea leaf outlet portion 12 are taken out onto the take-out conveyor 16 and transported to the next process.

In this embodiment, hot water jet pipes 9 are provided above and below the net conveyor 1, and hot water is jetted onto the fresh tea leaves A. If hot water can be applied to the fresh tea leaves A, there will be no problem from above or below the fresh tea leaves. If hot water jet pipes 9 are provided on both the top and bottom, hot water will be applied evenly on the front and back of the fresh tea leaves A. Can do. There is no problem even from the bottom.
図９、１０を参照して、熱湯の循環の実施例６を説明する。ネットコンベヤ１の下部に集湯板４５を設け、熱湯噴出管９Ａ、９Ｂの熱湯噴出口８から噴出して、茶生葉へ当たった湯を回収する。この湯を配管４６によって、熱湯タンク３９、４０へ送る。この途中で弁５０、５１を設けておき、湯を循環させる必要がないときは、弁５０を閉じ、弁５１を開いて、排水口５２へ湯を排水することも可能である。配管４６によって熱湯タンク３９、４０へ送られた湯を、弁３４、３５によって熱湯タンク３９、４０へ振り分ける。熱湯タンク３９、４０へ注ぐ前には、フィルター３２、３３を通して、ゴミなどの不純物を取り除く。熱湯タンク３９には水配管４７を設置し、弁４８で量を調節して水を注ぐ。回収した熱湯と水があふれないように、一定以上になると排水するためのオーバーフロー４３を設けておくとよい。この熱湯タンク３９内の湯をボイラー３１による蒸気で温め、所定温度になるように弁３６を調節する。熱湯タンク３９で作った湯をポンプ１３Ｂで汲み上げ、熱湯噴出管９Ｂへ送り、再び茶生葉へ噴出する。他方、熱湯タンク４０には、回収した熱湯があふれないように、一定以上になると排水するためのオーバーフロー４４を設けておくとよい。この熱湯タンク４０内の湯をボイラー３１による蒸気で温め、所定温度になるように弁３７を調節する。熱湯タンク４０で作った湯をポンプ１３Ａで汲み上げ、熱湯噴出管９Ａへ送り、再び茶生葉へ噴出する。熱湯噴出管９Ａ、９Ｂから噴出して、茶生葉に当たった湯を再び集湯板４５で回収し、熱湯タンク３９、４０へ注いで、循環させる。熱湯噴出管９Ａ、９Ｂへ送る熱湯がそれぞれ無くならないように、弁３４、３５で開き具合を調節する。熱湯タンク３９、４０には、最後に熱湯を排水するための弁４１、４２を設けておく。 With reference to FIGS. 9 and 10, a sixth embodiment of hot water circulation will be described. A hot water collection plate 45 is provided in the lower part of the net conveyor 1 and is ejected from the hot water outlet 8 of the hot water jet pipes 9A and 9B to collect hot water hitting the fresh tea leaves. This hot water is sent to the hot water tanks 39 and 40 through the pipe 46. In the middle of this, valves 50 and 51 are provided, and when it is not necessary to circulate hot water, it is possible to close the valve 50 and open the valve 51 to drain the hot water into the drain port 52. Hot water sent to the hot water tanks 39 and 40 by the pipe 46 is distributed to the hot water tanks 39 and 40 by the valves 34 and 35. Before pouring into hot water tanks 39 and 40 , impurities such as dust are removed through filters 32 and 33. A water pipe 47 is installed in the hot water tank 39 , and the amount is adjusted by a valve 48 to pour water. In order to prevent the recovered hot water and water from overflowing, it is preferable to provide an overflow 43 for draining water when the temperature exceeds a certain level. The hot water in the hot water tank 39 is warmed with steam from the boiler 31, and the valve 36 is adjusted to a predetermined temperature. Hot water made in the hot water tank 39 is pumped up by the pump 13B, sent to the hot water ejection pipe 9B, and ejected again to the fresh tea leaves. On the other hand, the hot water tank 40 may be provided with an overflow 44 for draining when the temperature of the recovered hot water exceeds a certain level so as not to overflow. The hot water in the hot water tank 40 is warmed with steam from the boiler 31 and the valve 37 is adjusted so as to reach a predetermined temperature. Hot water made in the hot water tank 40 is pumped up by the pump 13A, sent to the hot water jet pipe 9A, and jetted again to the fresh tea leaves. The hot water sprayed from the hot water jet pipes 9A and 9B and hit the fresh tea leaves is again collected by the hot water collecting plate 45, poured into the hot water tanks 39 and 40 , and circulated. The degree of opening is adjusted by the valves 34 and 35 so that the hot water sent to the hot water jet pipes 9A and 9B is not lost. The hot water tanks 39 and 40 are finally provided with valves 41 and 42 for draining the hot water.
図１１に煎茶製造工程を経る場合のフローを示す。前記のように茶生葉を処理する工程を茶生葉処理工程とし、その後、一般的な煎茶製造工程である粗揉工程、揉捻工程、中揉工程、精揉工程、乾燥工程を行なう。 FIG. 11 shows a flow when the sencha manufacturing process is performed. The process for treating fresh tea leaves as described above is referred to as a fresh tea leaf treatment process, and thereafter, a rough brewing process, a twisting process, a middle brewing process, a brewing process, and a drying process, which are general sencha manufacturing processes, are performed.
図１２に、釜炒り茶製造工程を経る場合のフローを示す。前記のように茶生葉を処理する工程を茶生葉処理工程とし、その後、釜炒り工程、粗揉工程、揉捻工程、中揉工程、乾燥工程を行なう。このようにすることで、煎茶製造工程とは殺青方法が異なり、風味が異なる茶を製造することができる。 In FIG. 12, the flow in the case of going through a pot roasted tea manufacturing process is shown. The process for treating fresh tea leaves as described above is referred to as a fresh tea leaf treatment process, and thereafter, a pot roasting process, a rough koji process, a twisting process, a middle koji process, and a drying process are performed. By doing in this way, the tea- killing method differs from a sencha manufacturing process, and the tea from which a flavor differs can be manufactured.
