Description

The all-glass construction and design of the spray assembly minimises any possible contamination and will produce a free-flowing, near-spherical powder. In the spray-drying process the product is introduced in liquid form and emerges as a dry, fine powder. Thermal shock is minimal.

The process may be used for powder coating (agglomeration) where the fine product is adhered together into small balls with the aid of filmogen.

Other processes where spray drying is found to be successful are micro-encapsulation and englobulation.

A fine jet of the liquid to be dried is brought into contact with a hot air stream. This evaporates the spray moisture and carries the solid particles into the cyclone separator. The solids are collected in a sample jar at the base of the cyclone and the exhaust vapour is directed to the outside atmosphere, or fume/dust extractor.
