With the development of the society, the unchanging things will be eliminated by the society. The fruit dryer, which can be developed so rapidly, is the representatives which has follow the dynamic changed market. The fruit dryer has broken obsolete rules and has bring a lot of new things for meeting the current market development of enterprises.

Why more and more users currently trying to abandon the previous traditional equipment and turn to adopt new air energy heat pump dryers? The reason is that, the heat pump dryer is a gentle drying method, which is close to natural drying. The evaporation rate of surface moisture is close to the migration rate of internal moisture to the surface, so that the dried mango has good quality, good color and high quality .

The fruit dryer is a new type of high-efficiency and energy-saving dryer. Its working principle is based on the principle of reverse Carnot cycle, which uses a small amount of electric energy. It uses compressor to make the refrigerant turn from vapor into a gaseous state in the evaporator after passing through an expansion valve. It also absorbs a large amount of heat energy in the air. The gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure gas, and then enters into the condenser to release heat. Afterwards, the drying medium is heating continuously and could be heat up to 40℃～85 ℃. Compared with the normal electric heating dryer, the heat pump fruit dryer saves 2/3 of the electric energy.
