[0054] Working principle:

[0055] The air source heat pump principle is used for drying edible fungi, wherein the air source heat pump is a direct heating unit in the embodiment, and includes a heat absorbing fan, an evaporator, a compressor, a condenser, a finned heat exchanger and an expansion valve.

[0056] The working medium runs a circle in the closed loop, and is circulated once, or the working medium is circulated once from entering the loop to discharging the loop. In the circulation, the heat-carrying working medium is the material itself (working medium) of the air source heat pump system, and heat is transferred through the change of the state of the working medium (i.e. the heat absorbing is changed into steam, the steam is condensed to release the latent heat of vaporization and is condensed into water again). At the same time, the heat converted from the external work consumed by the compressor is also supplemented into the system. In this way, the purpose of heat pump operation and heat supply is achieved. Through heat supply, the drying of edible fungi is achieved.

[0057] In the running process, the working medium in the closed loop absorbs the heat of the low-temperature heat source in the evaporator and vaporizes, the vaporized working medium vapor is condensed by releasing heat after compression, and is further cooled by the expansion valve to become the original liquid medium. At the same time, the heat absorbing fan continuously sends air to the evaporator to ensure that the working medium in the evaporator vaporizes. There is also a circulating fan continuously circulating air at the condensing end, and the heat released by the condenser is diffused into the environment of the second cabinet cavity, so that the vapor working medium in the condenser changes into liquid and returns to the evaporator for recycling again, so as to heat the environment of the second cabinet cavity, evaporate the moisture in the edible fungi by increasing the temperature, and realize the drying of the edible fungi.

The person skilled in the art can make equivalent changes or replacements to the related technical features without deviating from the principles of the utility model, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
