Description
本考案は、農産魚介類などの乾燥、例えば薩摩芋の乾燥において、乾燥斑が無く、色・艶を良好な仕上がり状態とする加湿装置を備えた乾燥機に関する。 The present invention relates to a dryer provided with a humidifying device that has no drying spots and has a good finish in color and luster when drying agricultural seafood and the like, for example, drying sweet potatoes.
従来、農産魚介類などの乾燥、例えば薩摩芋を乾燥する際、蒸気等で柔らかくした薩摩芋をスライスし、スライスされた薩摩芋を孔の開いた乾燥用トレイ（以降、一般的名称で「えびら」という）に並べた後、天日により乾燥、或いは棚を設けた台車に１０段乃至２０段程度差し込み乾燥室に搬入して乾燥する等の乾燥方法が行われている。 Conventionally, when drying agricultural seafood, for example, sweet potatoes, the sweet potatoes softened with steam etc. are sliced, and the sliced sweet potatoes are called a drying tray with holes (hereinafter, the general name is "shrimp"). ), And then dried in the sun, or 10 to 20 steps are inserted into a trolley with shelves and carried into a drying chamber for drying.
特許文献１に開示された発明においては、海苔などを乾燥する際、密閉式の乾燥機に中間床を配置し上側乾燥室と下側乾燥室とに区画し、各々の乾燥室にシャッターで開閉する吸入口及び排気口を設け、また各々の乾燥室に設けた湿度センサーで、室内の湿度を区々に検出し、その湿度が設定値である時は乾燥室で生成される加温、恒湿空気を循環し、その湿度が設定値以下である時は、乾燥室の加湿器を作動させ湿度を設定値に維持し、またその湿度が設定値以上である時は、乾燥室に設けた排気口を開放して多湿空気を排出しつつ、乾燥室に設けた吸入口より外気を導入して湿度を設定値に維持する構成となっている。
しかしながら、このような構成の乾燥機においては、乾燥室内に加湿器が設けられているため、乾燥中に被乾燥物から出る成分に長時間晒され加湿器の劣化を早め、また高頻度でのメンテナンス及び清掃が求められる乾燥機となっている。
In the invention disclosed in Patent Document 1, when drying seaweed or the like, an intermediate floor is arranged in a closed-type dryer, which is divided into an upper drying chamber and a lower drying chamber, and each drying chamber is opened and closed by a shutter. Humidity sensors provided in each drying chamber detect the humidity in the room, and when the humidity is the set value, the heating and constant temperature generated in the drying chamber are generated. Moist air is circulated, and when the humidity is below the set value, the humidifier in the drying chamber is operated to maintain the humidity at the set value, and when the humidity is above the set value, it is provided in the drying chamber. The structure is such that the humidity is maintained at the set value by introducing outside air from the suction port provided in the drying chamber while opening the exhaust port to discharge humid air.
However, in a dryer having such a configuration, since a humidifier is provided in the drying chamber, it is exposed to the components emitted from the object to be dried for a long time during drying, which accelerates the deterioration of the humidifier and frequently occurs.
