[0002] As we all know, a spray dryer is a device that can complete drying and granulation at the same time. According to the process requirements, the pressure, flow rate and size of the spray hole of the liquid pump can be adjusted to obtain the required spherical particles of a certain size ratio. The spray dryer is a kind of continuous atmospheric pressure dryer. The liquid material is sprayed into a mist with special equipment, so that it contacts with hot air and is dried. It is used to dry some heat-sensitive liquids, suspensions and viscous liquids, and is also used to dry fuels, intermediates, soap powder and inorganic salts.

[0003] The existing spray dryer often heats the air at the air inlet before filtering it, which means that when the filtering equipment needs to be cleaned, the machine needs to be shut down for cleaning. At the same time, if the air has just been heated, it is necessary to wait for the equipment to cool before subsequent operations can be performed. Utility Model Content
