The types of heat pump drying hot air blowers mainly include the following:
Classification by drying temperature range:
Low-temperature heat pump: The working temperature is between 10 and 45°C, suitable for drying temperature-sensitive materials.
Medium-temperature heat pump: The temperature is between 45 and 65°C, suitable for drying most agricultural products and seafood.
High-temperature heat pump: The temperature is between 65 and 85°C, suitable for materials that require high-temperature volatilization of internal bound water.
Ultra-high-temperature heat pump: The temperature is between 85 and 105°C, suitable for special high-temperature drying needs.
Classification by heat source:
Open-loop heat pump: The external unit absorbs ambient air energy, and the internal unit releases energy in the drying room. It is suitable for occasions with ambient temperature above 10 degrees and drying temperature within 55 degrees.
Closed-loop heat pump: Both the evaporator and the condenser are placed in the drying room, and the energy comes from the power consumption in the drying room. It is suitable for low-temperature and high-humidity environments.
Open-closed loop cooling and heating heat pump: Combines the advantages of open loop and closed loop, suitable for a variety of environmental conditions.
Classification by structure:
Drying room integrated machine: The unit comes with a drying room, which is integrated with the host.
Embedded integrated machine: There is no drying room, but the unit reserves a fixed space to install the drying room.
Split machine: There is only a heat pump host, and the drying room needs to be built separately.
Classification by function:
Hot air drying type: Absorb heat through the evaporator, heat the air in the room, and take away moisture.
Heat pump dehumidification drying type: Through a closed cycle, the moisture is reduced to below the dew point temperature through the evaporator, the moisture is precipitated, and the dry air is circulated again.
