Many people not only like to eat fresh longan, but also like to eat dried longan, so how do we make fresh longan into dried longan?
 
1. The air energy heat pump dryer is a new type of high-efficiency and energy-saving dryer. It uses the principle of reverse Carnot cycle and uses a small amount of electric energy to drive the compressor to run. The high-pressure liquid working medium evaporates into a gaseous state in the evaporator after passing through the expansion valve. , and absorb a large amount of heat energy in the air, the gaseous working medium is compressed by the compressor into a high-temperature, high-pressure liquid state, and then enters the condenser to release heat, and then through the fan, the heat generated by the condenser is sent to the drying room for heating and drying. Dry.
2. Since the air energy heat pump dryer is not affected by the external environment, weather, season and climate, it can work continuously for 24 hours, and can well guarantee the quality, color, appearance and active ingredients of the drying product, which can meet different requirements. Therefore, it can be widely used in drying operations in the fields of aquatic products, meat products, Chinese medicinal materials, agricultural and sideline products, fruits and vegetables, food, grains, seeds, clothing, tea, paper, wood, industry and other fields.
