The future development of tea drying machine will be in-depth study of drying mechanism and material drying characteristics, mastering the optimal operating conditions for different materials, developing and improving the dryer; in addition, large-scale, high-strength, high-economic, and improved raw materials The adaptability and product quality are the basic trends in the development of dryers; at the same time, further research and development of new types of dryers that are efficient and adaptable to special requirements, such as combined dryers, microwave dryers and far-infrared dryers.

The development of tea drying machine should also pay attention to energy conservation and comprehensive utilization of energy, such as using various joint heating methods, transplanting heat pump and heat pipe technology, developing solar dryers, etc.; and developing automatic control technology of dryers to ensure optimal operating conditions. In addition, as humans pay more attention to environmental protection, improving the environmental protection measures of dryers to reduce the leakage of dust and exhaust gas will also be the direction that needs further research.

After the start-up, the refrigerant is compressed by the compressor from the low temperature and low pressure state to the high temperature and high pressure steam. The high-temperature and high-pressure steam flows into the condenser and the secondary condenser, and the heat is taken away by the cooling medium by heat exchange, and the temperature is lowered, and the high-temperature and high-pressure vapor becomes a normal-temperature high-pressure liquid because of condensation. The normal temperature and high pressure liquid refrigerant flows through the expansion valve, because the throttle action pressure of the expansion valve is lowered, so that the refrigerant becomes a normal temperature and low pressure liquid. After the normal temperature and low pressure liquid enters the evaporator, the liquid refrigerant evaporates into a low pressure and low temperature gas due to the pressure drop. When the refrigerant evaporates, it absorbs a large amount of heat of the compressed air, so that the temperature of the compressed air drops to the purpose of drying. The evaporated low-temperature low-pressure refrigerant vapor flows back from the suction port of the compressor, is compressed and compressed, and is discharged to the next cycle.
