Description
【発明の詳細な説明】 （イ） 産業上の利用分野 この発明は、茶葉の仕上乾燥機に関する。[Detailed description of the invention] (b) Industrial application field The present invention relates to a finishing dryer for tea leaves.
（ロ） 従来の技術
従来、製茶の仕上工程である乾燥火入れは、熱風によっ
て炉体や器内の雰囲気温度を高めて、対流や伝導により
茶葉を加熱することによって行われている。(b) Conventional technology Traditionally, drying, which is the finishing process of tea manufacturing, is carried out by raising the atmospheric temperature in the furnace body or container using hot air and heating the tea leaves by convection or conduction.
（ハ） 発明が解決しようとする問題点しかしながら、
上記の熱風による仕上乾燥で°は、茶葉を一様に乾燥さ
せることが困難で、例えば、茶葉の葉先は薄いので加熱
しすぎになり、粉茶になりやすく、茎や芽の部分は充分
に加熱されず苦渋味が強く、青奥昧が残り、茶葉の旨味
と香味を充分に引き出すことが困難であるという問題点
があり、また、熱風による加熱では対流熱と伝導熱が主
であるため、茶葉の内部まで加熱するには高温度と長時
間の加熱を要し、茶葉の乾燥・火入れに要する正味熱量
の数倍の熱量を消費していた。(c) Problems that the invention seeks to solveHowever,
With the above-mentioned finishing drying using hot air, it is difficult to dry the tea leaves uniformly.For example, the tips of the tea leaves are thin, so they are easily overheated and become powdered tea, and the stems and buds are not dried properly. There are problems in that the tea leaves are not heated properly, resulting in a strong bitter and astringent taste and a dark green flavor, making it difficult to fully bring out the flavor and flavor of the tea leaves.In addition, when heating with hot air, convection heat and conduction heat are the main sources. Therefore, heating to the inside of the tea leaves required high temperatures and long heating times, consuming several times the net heat required for drying and pasteurizing the tea leaves.
そのため、茶葉の乾燥度に応じて加熱温度を迅速に調節
することが困難であった。Therefore, it has been difficult to quickly adjust the heating temperature depending on the degree of dryness of the tea leaves.
（ニ） 問題点を解決するための手段

受けて茶葉が有する旨味と香味を充分に引き出すことが
できるようになる。Far-infrared rays penetrate deep into the tea leaves and heat them from within.As the tea leaves are stirred and turned upside down in a floating state as described above, the entire tea leaf is uniformly irradiated with far-infrared rays. receive. Therefore, the tips of the leaves are prevented from being heated and turned into powdered tea, and the buds and stems are also sufficiently heated to fully bring out the flavor and flavor of the tea leaves.
また、遠赤外線放射体から照射する熱量は、同放射体の
温度を指標として自動的にコントロールすることができ

る。In addition, the amount of heat emitted from the far-infrared radiator can be automatically controlled using the temperature of the radiator as an index, and by consistently performing finish drying without uneven drying, it is possible to achieve perfectly cooked high-quality rice. We can produce quality tea leaves.
また、遠赤外線の波長を茶等に吸収されやすい６〜９μ
ｍの長波長のものとすることで熱効率が高く、大幅にエ
ネルギーを節減することができる。In addition, the wavelength of far infrared rays is 6 to 9μ, which is easily absorbed by tea etc.
By using a long wavelength of m, thermal efficiency is high and energy can be significantly saved.
