Low-temperature drying is critical for preserving the color, aroma, nutrients, and active ingredients of high-value food and medicinal products. Traditional hot air drying often causes overheating, uneven moisture removal, and unsustainable energy consumption.
Guoxin’s Air Energy Heat Pump Dryer is an integrated energy-saving system that combines dehumidification and heating. It is equipped with multiple heat recovery devices, effectively improving the utilization rate of thermal energy for long-term industrial storage.
Our technology breaks the efficiency barrier of conventional thermal systems by extracting energy from the environment.
Environmental Synergy: 3/4 of the heating energy is provided by the environment (air, water, or soil) for free.
Electrical Efficiency: Only 1/4 of the total energy is provided by electricity to drive the compressor.
Cost Advantage: Compared with ordinary heat pump drying equipment, our system saves more than 60% in energy and greatly reduces operating costs.
Technical Workflow:
The compressor transforms refrigerant into high-temperature and high-pressure gas → The gas enters the condenser to release heat → The circulating fan heats the air in the chamber (Max 75°C) → Moisture in the material evaporates → Fresh air dehumidification system exhausts the moisture.
Guoxin heat pump dryers are engineered to outperform traditional methods in both quality and cost.
