technical field

The utility model relates to the technical field of spray dryers, in particular to a centrifugal granulation spray dryer.

Background technique

The 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 the size of the nozzle hole of the material liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio. Powdered, granular solid products are produced from solutions, emulsions, suspensions and liquid pasty raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise standards, spray drying is a very important process. ideal craftsmanship;
