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.
