The spray assembly’s structure and design minimize any potential contamination and result in a free-flowing, nearly spherical powder. The substance is delivered in liquid form during the spray-drying process and leaves as a dry, fine powder. There is little thermal shock. The procedure, which involves using filmogen to bind the fine product into tiny balls, can be utilized for powder coating (agglomeration). Micro-encapsulation and englobulation are two other techniques where spray drying is effective.A heated air stream is in contact with a fine jet of the liquid to be dried. This drives the solid particles into the cyclone separator while also evaporating the spray moisture. The exhaust vapor is sent to the outside atmosphere or a fume/dust extractor, and the solids are collected in a sample jar at the foot of the cyclone.
