Closed cooling granulation equipment (spray coolers)is an equipment that sprays heated and melted substances into cold gas to condense and solidify them, so as to obtain spherical products. 
 
Microcapsule products can also be made by mixing a substance in the form of a core into a molten substance to cool and solidify it. 

Characteristic 

1. Products are spherical particles 
 
2. The product is very fluid, has good mechanical strength, and is not easy to damage 
 
3. The device has the advantages of simple operation, automatic operation and simple maintenance, and is suitable for large capacity continuous granulation 
 
4. Using the combination of equipment, continuous unmanned operation can be achieved 
 
5. Considering the flammability and dust explosion of the product, the safe operation of the device is guaranteed through the airtight and negative pressure nitrogen system
