ZN Heat Pump Dehydrator Working Process


A heat pump dehydrator acts as an efficient “heat mover” moving heat from the outside air into the drying chamber to dry food in an energy-saving way. The entire process is electric-driven, yet it saves 50-70% more electricity than traditional electric heating and offers automatic temperature and humidity control for simple operation.
Heat Absorption (Evaporation): The evaporator acts like a “heat sponge,” pulling warmth from the air, which makes the refrigerant evaporate into a low-temperature, low-pressure gas.
Compression & Heating: The compressor then “squeezes” this gas, making it high-temperature and high-pressure.
Heat Release (Condensation): The condenser releases this heat, warming the drying chamber’s air. This hot air then circulates over your chilies, efficiently removing moisture.
Expansion & Cooling: The refrigerant goes through an expansion valve, dropping in pressure and cooling back into a liquid, ready to start the cycle again.
Humidity Control: A specialized dehumidification system removes moisture, keeping the drying chamber perfectly dry.

Customizable Control for Optimal Drying
ZN heat pump dehydrators feature built-in control logic with preset heating curves, optimizing drying for various foods. Users can also easily adjust these heating curves to fit specific needs. This ensures your materials are dried to their best condition every time.

Industry-Leading Components for Enduring Quality
All ZN heat pump dehydrators feature key components from industry-leading suppliers. For instance, we use compressors from Copeland and Mitsubishi, and plate heat exchangers from Swep, ensuring both high quality and long service life.
