Spray Coolers are used for obtaining powders from molten products like oils, fats, glycerine Etc. In the process of spray cooling the products in molten form are sprayed through nozzle or rotating disc atomizer in a cooling chamber. This sprayed material is bought in comtact with either ambient air or cooled air depending upon the melting point of the product. As the cooling takes plance the cooled product in powder form is discharge from the bottom of the cooling chamber. Particle sizes up to 500 microns are possible by spray cooling.
