The pressure 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 nozzle size of the material liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio. Due to its fast drying speed, wide application range, and the characteristics of hot air drying and cold air granulation, the pressure spray dryer is deeply loved by chemical, food, pharmaceutical, ceramic and other industries. spray granulation is applicable to various fertilizers, alumina, washing powder, etc., and cooling granulation is applicable to paraffin, glyceride, amino fatty acid, etc.
