Edible fungus dried air circulation treatment device

Abstract

The invention discloses an edible fungus dried air circulation treatment device which comprises a baking chamber, an air treatment unit, an air supply header pipe, an air mixing device, and an air supply pore plate and an air return pore plate which are arranged in the baking chamber in parallel, wherein the baking chamber is segmented into an air supply static pressure space, an air return static pressure space and a baking workshop; the air treatment unit consists of an air inlet, a solid adsorption and dehumidification device, a heat pump loop, a fan, an auxiliary electric heater and an air outlet; the heat pump loop consists of a condenser and three groups of compressors and an evaporator assembly which are arranged in parallel; and the compressors and the evaporator assembly comprise an expansion valve, an evaporator and compressors which are sequentially connected. By employing the parallel air supply mode and the general-branch-general-branch refrigerant distribution mode, the air distribution is improved, and the uniformity and stability of the air flow and temperature field in the baking chamber during operation are guaranteed, so that the consistency of the baking effect is guaranteed, and the energy consumption in the process of operating the baking chamber at a low load is reduced.

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 for drying edible fungi. Background technique [0002] The baking room is widely used in the drying and preservation of agricultural surplus products and the processing of flavored food. At present, most of the drying rooms are hot air convection drying equipment heated by flue gas, and the heating method is mostly one furnace and one chimney tempering heating type drying room. This kind of traditional baking room has simple equipment, low initial investment, and is still used in rural areas. However, there are still a series of problems such as low baking efficiency, poor quality of dried food, complicated baking operation and environmental pollution. [0003] In order to solve a series of problems caused by the traditional baking room, after long-term ...

AI Technical Summary

Problems solved by technology

The disadvantages of this parallel mode are: (1) When the air handling unit is running at low load, only part of the heat pump system is running, and the temperature and humidity of the treated air are not uniform at this time

(2) When the air handling unit is running at low load, only a part of the heat exchange coil can be used, and the utilization rate of the heat exchange coil is very low

(3) Due to the independent operation of multiple sets of systems, the uniformity of the treated air cannot be guaranteed, especially when the air entering the air handling unit is uneven, it is difficult for multiple sets of systems to coordinate effectively, and the unevenness of the treated air will further increase
