The basic working principle of food dryer

Use a heat pump evaporator to absorb heat from the external ambient air, or recover waste heat that needs to be exhausted during the drying process. After the compressor works, the energy is transported (transferred) to the drying box. The hot air in the drying box is heated by repeated circulation, absorbing the moisture in the material, cooling and humidifying economically, and dehumidifying or condensing the water through the hot air to drain and take away the water in the material, ultimately achieving continuous drying of the material.
