Description

【考案の詳細な説明】この考案は、製茶用蒸機の蒸熱処理に用いるボイラに係

面下に浸水させることによって、湿り蒸気と乾き蒸気を
適宜に発生させ、茶の原、葉に適応した蒸熱処理をする
ことを目的とする。[Detailed description of the invention] This invention relates to a boiler used for steam heat treatment in a tea steamer. By exposing a part of the smoke pipe above the water surface or submerging it under the water surface, wet steam and dry steam can be produced. The purpose is to generate a suitable amount of heat and to perform a steaming process that is suitable for tea grounds and leaves.

茶の凍菜に蒸気をあてて蒸すことが蒸熱処理であるが、
凍菜は季節の移行とともにかたさを変え、一番茶は葉も
やわらかくて葉内の水分も多いが、二番茶三番茶とすす
むにつれて葉はかたさを増し、葉内の水分は減少する。Steaming is done by applying steam to frozen tea leaves.
Frozen greens change their hardness as the seasons change, and first-class green tea leaves are soft and have a lot of moisture in them, but as they progress to second and third-grade green tea, the leaves become harder and the moisture content in the leaves decreases.

このような凍菜の性質に対応させて蒸熱処理をするには
、凍菜の初期のものに対しては乾いた蒸気を、後期のも
のに対しては湿り蒸気をあてて蒸熱すれば品質の安定し
た蒸熱茶が得られる。In order to perform steaming treatment that corresponds to the characteristics of frozen vegetables, dry steam is applied to the early frozen vegetables, and wet steam is applied to the later frozen vegetables to improve the quality. Stable steamed tea can be obtained.

従来この種の方法に、ボイラに附属する給水タンクを上
下させることによってボイラ内の水面の高さを変え、水
量の多いときには湿り蒸気を、少ないときには乾き蒸気
を発生させて凍菜に対応させたものがある。Conventionally, this type of method was used to change the height of the water level inside the boiler by raising and lowering the water supply tank attached to the boiler, producing wet steam when the amount of water was high and dry steam when it was low, making it suitable for frozen vegetables. There is something.

またボイラにスーパーヒータを装着して過熱蒸気を発生
させて対応させたものがある。There is also a boiler equipped with a super heater to generate superheated steam.

しかし前者はほとんど効果がなく、後者のものはスーパ
ーヒータそのものが大きく、かつ高価であるほか、製茶
用には特に必要としない。However, the former has little effect, and the latter has a large and expensive superheater, and is not particularly necessary for tea production.

本考案は前記のような実情から考案したもので、図につ
いて説明するに、１は缶体、２は炉筒、３は炉筒と焔箱
４を介して連通ずる煙管群で、その二部の煙管３′は傾
斜している。This invention was devised from the above-mentioned circumstances. To explain the figure, 1 is a can body, 2 is a furnace tube, 3 is a group of smoke pipes that communicate with the furnace tube through a flame box 4, and the two parts are The smoke pipe 3' is inclined.

５は検相、６煙突。７は蒸気溜で、その送出口８から配
管９を介して蒸機の蒸気室（図示時）に連通ずる。5 is a phase inspection, 6 is a chimney. Reference numeral 7 denotes a steam reservoir, and its outlet 8 communicates with the steam chamber of the steamer (as shown) via piping 9.

１０は水面計、１１はドレン、１２は給水口、１３は炉
筒１の前面に装着した燃焼器である。10 is a water level gauge, 11 is a drain, 12 is a water inlet, and 13 is a combustor attached to the front of the furnace tube 1.

そこで缶体１にａ水面まで、すなわち傾斜煙管３′が浸
水するまで水を流入し、バーナ１３を燃焼させれば、水
はやがて沸とうして湿り気の多い蒸気が発生し、蒸気溜
り７送出ロ８配管９を通過して蒸機（図示時）に送られ
る。Therefore, if water flows into the can body 1 up to the water level a, that is, until the inclined flue pipe 3' is submerged in water, and the burner 13 is burned, the water will eventually boil and produce humid steam, which will be sent to the steam reservoir 7. It passes through the pipe 9 and is sent to the steamer (as shown).

次にドレン１１を開き水面計１０を見つつ水面ａ′に達
するまで流出させれば、傾斜煙管の一部３′は水面上に
露出し、この露出した煙管３′には高熱の燃焼炎が通過
し加熱されているから、発生した蒸気は過熱されて乾き
蒸気となって、前記同様に蒸機に送られるのである。Next, when the drain 11 is opened and the water is allowed to flow out until it reaches the water surface a' while watching the water level gauge 10, a part 3' of the inclined smoke pipe will be exposed above the water surface, and a high-temperature combustion flame will be in this exposed smoke pipe 3'. Since it passes through and is heated, the generated steam is superheated and becomes dry steam, which is then sent to the steamer in the same way as above.

本考案は、煙管群３の一部３′を傾斜させ水面ａ′上に
露出、あるいは水面ａ下に浸水させるようにしたから、
傾斜煙管の一部が露出しているときには乾き蒸気を、浸
水しているときには湿り蒸気を発生することができ、冒
頭に述べた目的事項を満足する。In the present invention, a part 3' of the smoke pipe group 3 is tilted so that it is exposed above the water surface a' or submerged below the water surface a.
Dry steam can be generated when a part of the inclined smoke pipe is exposed, and wet steam can be generated when it is submerged in water, thus satisfying the purpose stated at the beginning.

また水面ａ、ａ’の維持は、水面計１０を監視しつつ給
水または排水をすればよいから、操作が至って楽となる
。Furthermore, the water levels a and a' can be maintained by simply supplying or draining water while monitoring the water level gauge 10, making the operation extremely easy.
