A middle air supply type edible mushroom circulation drying device

Abstract

The invention discloses a middle air supply type edible fungus circulation drying device, which comprises an enclosure structure, a drying area, an air treatment device, an air supply main pipe arranged on the left side of the enclosure structure, and a vertically arranged air supply non-uniform orifice plate The space below the air handling device is divided into air supply main pipe, drying area, and return air main pipe by the non-uniform orifice plate of return air along the air flow direction. The air handling device is connected with the drying area through the air supply main pipe; A group of air supply holes and a group of return air holes are arranged on the left and right sides. The invention adopts the air supply in the middle of the drying surface to improve the drying air flow structure, ensure the uniform and stable air flow at the drying surface, improve the drying efficiency and reduce the energy consumption.

Description

technical field [0001] The invention belongs to the technical field of building environment and equipment engineering, and relates to an air circulation treatment system, in particular to an air circulation treatment system with an intermediate air-supply edible fungus heat pump drying air. Background technique [0002] As a large agricultural country in my country, agricultural energy conservation is of great significance in the strategy of energy conservation and emission reduction. Many agricultural and sideline products (including edible fungi) must be dried before and during storage, transportation and processing into food or other daily necessities because they are rich in water (generally with a moisture content of more than 80%), and drying operations generally require Uses a lot of energy. Hot air drying technology is the mainstream technology in the edible fungus deep processing industry, and its production efficiency directly affects the effect of agricultural en...

AI Technical Summary

Problems solved by technology

However, the air supply orifice does not distribute the air volume according to the actual situation, and the parallel air supply method in the baking workshop cannot fully achieve the effect of uniform and stable air flow organization, and the drying effect of edible fungi is not good.

Moreover, the air supply port adopts constant air volume, and the same air volume is delivered to different drying spaces, failing to take into account the air volume cycle characteristics, which not only causes waste, but also affects the drying effect of edible fungi

[0004] Publication No. 104082397A patent application for an energy recovery edible fungus drying device (see figure 2 ) adopts the form of air supply from top to bottom, and adopts the parallel air supply structure set by double-hole plates, but it can only form a cycle inside the device, and there are certain limitations in the use of air volume and wind speed, which will have a greater impact on the lower part , thus affecting the wind speed and air volume in the drying zone, reducing the drying quality in the lower part of the drying zone

Moreover, the air supply and return air orifices adopt uniform slit orifices, which have a great influence on the airflow direction, resulting in differences in air temperature and wind speed in the horizontal direction in the drying area, and the drying effect is not good.
