Drying room for deep processing of agricultural and sideline products

Abstract

The invention relates to a drying room for the deep processing of agricultural and sideline products. The drying room comprises a drying chamber, an air blower, heat source bellows, an air delivery pipe, an air return pipe and moisture removing pipes, wherein an air outlet of the air blower is connected with an air inlet through the heat source bellows and the air delivery pipe; the air suction end of the air blower communicates with an air return opening through the air return pipe; a fresh air opening and a regulating air valve are further arranged on the air return pipe; three to four transverse guide plates are arranged at the lower part, directly facing the air inlet, in the drying chamber from the near to the distant; and each guide plate can rotate or swing around rotating shafts at the two ends of the guide plate. When the drying room carries out drying processing on agricultural and sideline products, hot air in the drying room is enabled to evenly circularly flow up and down. The whole temperature difference of the drying room is reduced, and temperature and humidity distribution is relatively even.

Description

technical field [0001] The invention relates to the technical field of deep processing of agricultural and sideline products, and more specifically relates to a drying room for deep processing of agricultural and sideline products. Background technique [0002] The current ordinary drying device is not equipped with a hot air circulation system. In the early stage of drying agricultural and sideline products, the gas in the drying device is basically in a relatively static state, and the heat from the lower part of the drying device cannot be smoothly transferred to the upper part of the drying device, resulting in The temperature difference in the longitudinal direction of the room is very large, and it is easy to form a "cold air mass" in the upper part of the drying device. In this way, the temperature and humidity distribution in the drying device is not uniform, so that the deep processing and baking of agricultural and sideline products cannot be carried out according t...

AI Technical Summary

Problems solved by technology

During the drying process of the hot air circulation and dehumidification device in the drying room, the path of the upward airflow is fixed, and the four corners of the drying room often become dead angles, resulting in uneven temperature and humidity in the baking area, unsatisfactory drying conditions, and long drying time. The drying effect is not uniform, so that the temperature of the drying room cannot meet the requirements of the process, which causes great difficulties for the drying of agricultural and sideline products
