Operating Principle of Fruit Drying Equipment - Food Dryer Machine


How does a food dehydrator works?

By allowing the refrigerant to continuously complete the thermal cycle process of evaporation (absorbing heat from outdoor environment) → compression → condensation (releasing heat in indoor drying room) → throttling → re evaporation. Thus, the heat in the external low-temperature environment is transferred to the drying room, and the refrigerant circulates in the system under the action of the compressor.

It completes the pressure rise and temperature rise process of gaseous state in the compressor (the temperature is as high as 75 ℃). It enters the condenser to release high-temperature heat to heat the air in the drying room. At the same time, it is cooled and transformed into liquid state. When it runs to the external machine, the liquid state quickly absorbs heat and evaporates and transforms into gaseous state again, and the temperature can be reduced to 15 ℃. At this time, the air around the heat absorber will continuously transfer heat to the refrigerant.
