What is an air energy heat pump dryer

Air energy refers to the low-grade thermal energy contained in the air, which is a type of clean energy equivalent to water energy, wind energy, solar energy, and tidal energy. The device that collects and utilizes air energy is called a heat pump, which is called air energy heat pump technology. It involves the fields of air energy heat pump hot water, air energy heat pump heating, air energy heat pump drying, etc. The usable equipment developed by air energy heat pump technology includes air energy heat pump water heater, air energy heat pump heating equipment, air energy heat pump dryer, etc. By using the reverse Carnot principle, the gas Freon is pressurized by the compressor to become a high-temperature and high-pressure gas (with a temperature of up to 100 ℃), which enters the indoor heat exchanger (condenser), and the refrigerant condenses and liquefies to release it. High temperature heat heats the air inside the drying room. The materials in the drying room are vaporized and evaporated by hot air, and the evaporated water vapor is discharged by the dehumidification system to achieve the purpose of drying the materials. The refrigerant after condensation and heat release is transformed into a low-temperature and low-pressure liquid through a throttle valve. Due to a sudden decrease in pressure, the liquid refrigerant enters the evaporator and continuously absorbs the low-level heat energy of the surrounding air, quickly evaporating into a gaseous state. The refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle. In this way, the refrigerant continuously circulates to transfer heat from the air to the drying room and heat the air temperature inside the heating room.

In contrast, although air heating heat pumps are much more expensive, their operating costs are lower than those of electric heating. Because the air energy heat pump is based on the "reverse card cycle principle", which converts low-grade heat in the air into high-temperature heat energy through a compressor, consuming 1KW of electrical energy and absorbing 2-3KW of heat from the air, the energy-saving effect is very good. With the government's electricity price subsidy, the operating cost will not be much higher than burning coal.

Drying machine equipment is currently the most commonly used drying equipment in selecting agricultural and sideline products. According to different equipment models, it can be divided into: chili dryer, mushroom dryer, tea dryer, tobacco dryer, cured meat dryer, etc. Drying machine equipment has been widely used in the market and is the preferred equipment for dehumidification and drying of agricultural and sideline products.

The air energy heat pump dryer belongs to energy-saving and environmentally friendly equipment, which is emission free, pollution-free, and odorless. The products produced by drying are green and of good quality, and are more easily recognized by more users. Air energy heat pump dryers are widely used in metallurgy, building materials, food, light industry, chemical industry, coal, pharmaceutical and mining industries due to their energy-saving and reliable operation, high operational flexibility, strong adaptability, and large processing capacity. The advantages of air energy heat pump dryers are widely used

Firstly, it has higher energy utilization efficiency, with an energy saving rate of approximately 40% -70% compared to steam drying;
Secondly, it has better drying technology quality and uses an air energy heat pump dryer to dry products without changing the appearance and color of the dried products
Thirdly, it has lower operating costs. Due to the fact that the heat pump drying system can save more energy than traditional drying techniques at the same drying temperature and wet material volume, it also reduces daily maintenance costs and saves certain costs
Fourthly, the drying process is fully automatic, with full process protection and automatic shutdown, saving labor and time,
Fifth, one click operation, embedded installation, quick machine installation, learned within a few minutes of operation, and the control screen can quickly detect faults, efficiently solving problems
Sixth, it is not affected by seasonal weather, as heat comes from the air, so it can work all day whether it is cloudy or rainy.
Seventh, there is no discharge of exhaust gas, wastewater, or waste residue, ensuring absolute safety and environmental protection.
