【従来の技術】[Prior Art]

従来、一般的に使用される送帯蒸機は、ネットコンベヤを用いた連続式の蒸機 であり、ネットコンベヤの上下に上蓋下蓋を設けて蒸熱室を形成し、この蒸熱室 には蒸気噴出管が配設されて、ネットコンベヤにより移送される茶葉に蒸気を当 てて蒸熱処理を行う様になっており、本考案のように木製の板材等の断熱性と吸 湿性を有する材料で、上蓋及び下蓋または内蓋を形成したものはなかった。 Conventionally, the generally used vaporizer is a continuous vaporizer that uses a net conveyor.The upper and lower lids are provided above and below the net conveyor to form a steam chamber. Is arranged to perform steaming heat treatment by applying steam to tea leaves transferred by a net conveyor. As in the present invention, a material having heat insulation and moisture absorption, such as a wooden plate material, is used for the upper lid. And none with a lower or inner lid.

【考案が解決しようとする課題】[Problems to be solved by the device]

蒸気により蒸熱される茶葉は、蒸熱時間の経過とともに次第に柔軟となり、茶 葉間の空隙は激減しボリュームは蒸熱前の茶生葉と比較して約〓となる。従って 蒸熱室前半部に比べ後半部では、茶葉層の厚みが約半分になる。蒸熱室前半部に おいては、茶葉間の空隙が広く茶葉と上蓋との空間も少い為、茶葉に蒸気が当り 易いが、蒸熱室後半部においては茶葉層が密になり、上蓋との空間も広がる為蒸 気はこの空間を素通りする様になるので、茶葉層と蒸気との温度差が生じ、上蓋 内面には凝縮した水滴が付着し易く、この水滴が落下して一見煮沸した様な状態 となる。一方蒸気の素通り分が多くなることにより、茶葉の温度が下り、茶葉層 内の蒸気が凝縮して水滴化が増して製茶品質を低下させるという問題点を有して いた。 本考案は、従来の技術の有するこのような問題点に鑑みてなされたものであり 、その目的とするところは、水滴の付着しない蒸熱葉が得られる蒸機を提供しよ うとするものである。 The tea leaves that are steamed by steam gradually become softer as the steaming time elapses, the voids between the tea leaves are drastically reduced, and the volume is about 〓 compared to fresh tea leaves before steaming. Therefore, the thickness of the tea leaf layer is about half in the latter half of the steam heating chamber. In the first half of the steam room, since the gap between the tea leaves is large and the space between the tea leaves and the upper lid is small, the steam easily hits the tea leaves. Since the space also expands, the steam will pass through this space, so there will be a temperature difference between the tea leaf layer and the steam, and condensed water droplets will tend to adhere to the inner surface of the upper lid, causing the water droplets to drop and boil at first glance. It will be in a state. On the other hand, there was a problem that the temperature of tea leaves decreased due to an increase in the amount of steam passing through, and the steam in the tea leaf layer condensed and water droplets increased, deteriorating the quality of tea production. The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a steamer that can obtain steamed leaves free from water droplets.

【０００４】[0004]

【課題を解決するための手段】 上記目的を達成する為に、特に茶葉の蒸熱程度が進んでボリュームが激減し、 上蓋と茶葉層との空間が増大する蒸熱室後半部の上蓋の内側に、木製の板材等の 吸湿性と断熱性とを有する材料で内蓋を形成し、内蓋と茶葉層間の空間を狭くす る。このことにより、茶葉層内部の茶葉まで蒸気と良く接触し又、蒸熱室の吸湿 保温性が増し、水滴の付着しない上質の蒸熱葉が得られる。 なお、内蓋とネットコンベヤの間隔が、蒸熱室前半の〓となる肉厚の内蓋を用 いることが望ましい。[Means for Solving the Problems] In order to achieve the above-mentioned object, in particular, inside the upper lid of the latter half of the heating chamber in which the degree of steaming of the tea leaves advances and the volume drastically decreases and the space between the upper lid and the tea leaf layer increases The inner lid is formed of a material having a hygroscopic property and a heat insulating property such as a wooden plate material, and the space between the inner lid and the tea leaf layer is narrowed. As a result, even the tea leaves inside the tea leaf layer are in good contact with the steam, the moisture absorption and heat retention of the steam chamber is increased, and high-quality steamed leaves free of water droplets are obtained. It is desirable to use a thick inner lid so that the distance between the inner lid and the net conveyor is 〓 in the first half of the steam room.

【作用】[Action]

吸湿性と断熱性を有する材料で、上蓋及び下蓋または内蓋を形成することによ って、蒸熱室内の保温性の向上と吸湿作用により水滴の付着を防ぎ、水滴が茶葉 に落下する事が少くなるので、煮沸した様な状態になりにくくなり、また余剰空 間が少なくなるので茶葉層内部まで蒸気が良く通る様になり、蒸熱程度の進行が 促進されて良好の蒸熱処理が行われる作用がある。 By forming the upper and lower lids or inner lids with a material that has hygroscopicity and heat insulation, it is possible to prevent water droplets from adhering to the tea leaves by improving the heat retention in the steam chamber and preventing moisture from adhering. As the amount of water is small, it does not easily become a boiling state, and since the excess space is small, the steam can pass well inside the tea leaf layer, promoting the progress of steaming and performing good steaming heat treatment. It has an effect.

【実施例】【Example】

本考案を図面に基づいて説明する。図中符号１３は装置を構成する架台を示し 、この架台１３には可変速のモータ９、チェーン１０を介して駆動されるエンド レスでネット状のコンベヤ１が張設されている。このコンベヤは生葉の供給部１ ５、蒸熱室１６、蒸気排出孔８を通って一巡する。生葉の供給部１５には、掻均 爪車６をもち、これの回転によってホッパー５に溜った茶葉を定量的に蒸熱室に 送り出している。蒸熱室前半部には蒸気噴出パイプがコンベヤ１の上下に配列さ れ、連続して送り込まれる茶葉に連続して蒸気を当てて蒸し、蒸熱室１６後半部 は、自己保有熱と余剰蒸気とによる余熱部で、蒸熱程度をさらに進めるところで ある。この付近まで茶葉が移送されると、茶葉は蒸熱効果によって次第にかさ密 度が増し、ボリュームが激減するため、茶葉層内部まで蒸気のとおりが悪化する とともに、上蓋２とコンベヤ１上の茶葉層との空間も増すために素通りする蒸気 の量が増加して茶葉温度が低下し、茶葉への水滴の付着を促進させている。そこ で、水滴の付着を防止するため、吸湿性、断熱性及び茶葉層と上蓋２との空間を 狭める効果を有する内蓋４を設ける。 The present invention will be described with reference to the drawings. In the figure, reference numeral 13 indicates a gantry constituting the apparatus, and an endless net-shaped conveyor 1 driven by a variable speed motor 9 and a chain 10 is stretched on the gantry 13. This conveyor goes through the fresh leaf supply unit 15, the steaming chamber 16 and the steam discharge hole 8 to complete a circuit. The raw leaf supply unit 15 has a scraping wheel 6 and by its rotation the tea leaves accumulated in the hopper 5 are quantitatively sent to the steam chamber. In the first half of the steaming chamber, steam jetting pipes are arranged above and below the conveyor 1, and steam is continuously applied to the tea leaves that are continuously fed to steam the steam. In the second half of the steaming chamber 16, self-owned heat and excess steam are used. It is about to further promote steaming in the residual heat section. When the tea leaves are transferred to this vicinity, the bulk density of the tea leaves gradually increases due to the steaming effect, and the volume of the tea leaves is drastically reduced. Since the space of the tea leaves also increases, the amount of steam passing through increases and the temperature of the tea leaves decreases, promoting the attachment of water drops to the tea leaves. Here, in order to prevent water droplets from adhering, an inner lid 4 having a hygroscopic property, a heat insulating property, and an effect of narrowing a space between the tea leaf layer and the upper lid 2 is provided.

【考案の効果】[Effect of the device]

吸湿性と断熱性を有するとともに、茶葉層と上蓋との空間を狭める効果のある 内蓋を設けた事に依り、水滴の付着が減少し、更に茶葉層内部まで蒸気が当り、 蒸熱程度の進行が促進されて、従来と同じ蒸熱時間であっても蒸熱程度は進むの で時間を短縮することができ、製品品質の向上と処理時間の短縮が可能となる。 In addition to having hygroscopicity and heat insulation, the inner lid, which has the effect of narrowing the space between the tea leaf layer and the top lid, reduces the adhesion of water droplets, and the steam also reaches the inside of the tea leaf layer to promote steaming. The steaming rate is promoted, and the steaming degree is increased even if the steaming time is the same as the conventional one, so that the time can be shortened, and it is possible to improve the product quality and shorten the processing time.
