[0002] An evaporator is a device used for heat exchange. Its main function is to heat liquid substances to their boiling point and convert them into gaseous form. Grains usually have a high water content after harvest and are prone to mildew and rot. The grains need to be heated by an evaporator to evaporate the water in them, thereby reducing the moisture content and extending the storage life of the grains. During the grain drying process, the dust carried by the grains will adhere to the fins of the evaporator, affecting the heat exchange efficiency and making the drying efficiency low. Secondly, the dust after cleaning needs to be collected and discharged in a centralized manner. In response to the above problems, the inventors proposed an automatic dust removal evaporator fan to solve the above problems. Utility Model Content
