Manual: BETE Spray Dry

Drying is the process of removing liquid from solids by evaporation. The drying process has been used for thousands of years to reduce transport weight and increase the storage life of numerous products and materials. For centuries, drying meant spreading a product out in the open air and letting the sun provide the energy for water evaporation. With the dawn of the industrial age, many different drying processes have been developed to increase drying speed and improve product quality and uniformity.

In the world of industrial dryers, there are few types that accept pumpable fluids as the feed material at the inlet end of the process and produce dry particulate at the outlet. Spray drying is unique in its ability to produce powders with a specific particle size and moisture content without regard for the capacity of the dryer and the heat sensitivity of the product. This flexibility makes spray drying the process of choice for many industrial drying operations.
