The operating principle and advantages of industrial heat pump dryers
With the development of the times and policy updates, in recent years, the country has vigorously promoted energy-saving and environmentally friendly products, and to a large extent promoted the development of new energy products. Air energy dryers are a very popular type of energy-saving and environmentally friendly products, and their popularization and promotion The degree is also further strengthened. Today we will discuss together what are the advantages of air energy dryers?
Analysis of the principle of efficient heat pump drying machine
The internal structure of the air energy water heater is mainly composed of four core components-compressor, condenser, expansion valve and evaporator.
Work flow: The compressor compresses the refluxing low-pressure refrigerant and turns it into high-temperature and high-pressure gas and discharges it. The high-temperature and high-pressure refrigerant gas flows through the copper pipe wound outside the water tank, and the heat is transferred to the water tank through the copper pipe, and the cooled refrigerant is in Under the continuous action of pressure, it becomes liquid and enters the evaporator after passing through the expansion valve. Because the pressure of the evaporator drops suddenly, the liquid refrigerant quickly evaporates and becomes gaseous, and absorbs a lot of heat. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator, and the temperature of the air drops rapidly and becomes cold air. Then the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.
The working principle of heat pump drying equipment is similar to the principle of air conditioning. Using the reverse Carnot principle, it absorbs a large amount of low-temperature heat energy in the air, which is compressed by a compressor to convert it into high-temperature heat energy, which is transferred to the drying chamber. The whole process is a process of energy transfer, not a process of energy conversion. There is no electric heating element to obtain heat, or the burning of combustible objects to obtain heat.
Summary: The working principle of a heat pump is to absorb the energy in the air, convert it into heat, and transfer it to the dry chamber, and at the same time discharge the air that has lost a lot of heat to the outdoor environment. This is the principle of the heat pump.
The entire drying process only uses electricity, does not produce various combustion residues, and does not produce exhaust gas. It is an environmentally friendly industrial drying equipment.
High-efficiency and energy-saving food dryer
The heat of the heated air in the air energy dryer is mainly to recover the sensible heat and replacement heat contained in the warm and humid air distributed in the drying room. The energy that needs to be input is only the power consumption of the heat pump compressor, and the heat pump also consumes a small amount Work can produce a lot of heat advantage.
Food drying equipment with precise control of temperature and humidity
When using an air dryer, if the material has relatively high requirements for the temperature and humidity of the air entering the drying room, you can adjust the evaporation temperature and condensation temperature of the working fluid in the evaporator and condenser to meet the texture and appearance of the material. Special requirements on the negative side.

The heat pump in the heat pump drying device also has a refrigeration function. The refrigeration function can be used to realize the low-temperature processing or preservation of a variety of materials in the season with fewer drying tasks. It can also expand the heating function of the heat pump to be a planting or breeding place in the cold season. Heating. The materials suitable for drying are mainly a large class of materials that can withstand a temperature between 20 and 80 degrees during the drying process. Currently, materials that are widely used include: wood, grains, biologically active materials, tea, paper, etc.
