Product introduction
Air-source heat pump dryer are energy-efficient drying devices based on heat pump technology, utilizing ambient air heat for drying operations. Their key advantages include low energy consumption, environmental friendliness, and precise temperature/humidity control. Widely used in food processing, agricultural product drying, and industrial applications, they are ideal for scenarios demanding high drying quality and energy efficiency.
Applications
Food Processing: Drying rice noodles, sausages, mushrooms, dried fruits, seafood.
Agriculture: Herbs (goji berries, honeysuckle), tobacco, grains (corn, rice).
Industry: Leather, paper products, ceramics, electroplated parts.
Eco-Friendly Replacement: Reduces carbon emissions by replacing coal-fired dryers.
Working Principle
Heat Pump Cycle System
Evaporator: Absorbs heat from ambient air, vaporizing low-temperature, low-pressure refrigerant.
Compressor: Compresses gaseous refrigerant to increase temperature and pressure.
Condenser: Releases heat from high-temperature refrigerant to warm air in the drying chamber.
Expansion Valve: Reduces refrigerant pressure and temperature before it re-enters the evaporator, completing the cycle.
Drying Process
Moisture in materials evaporates under hot airflow. Humid air is dehumidified via the heat pump system, with heat recovered for reuse, forming a closed-loop cycle that minimizes energy waste.
Key Advantages
High Efficiency & Energy Savings
Consumes only 1/3–1/4 of the energy of electric heaters and saves over 50% compared to coal/gas dryers.
Eco-Friendly
Zero combustion emissions, compliant with environmental regulations; safe for sensitive materials like food and herbs.
Precise Control
Temperature range: 30°C–80°C (adjustable); humidity control accuracy: ±5%, preventing over-drying or spoilage.
Versatility
Dries fruits, vegetables, herbs, seafood, cured meats, rice noodles, and industrial components.
Smart Operation
PLC touchscreen controls with preset drying curves; one-touch startup.
