DIRECT DRYING

One method of thermal processing is by using Direct Drying. Direct dryers transfer heat by contacting the product with a heated gas---usually hot air. Thermal Processing by using this method is an ideal choice for removing moisture and also efficient for heat-sensitive products because the product temperature is reduced by evaporative cooling. The drop in product temperature can eliminate the need for operating under vacuum.

It is often advantageous to combine milling and direct drying in a single unit. This saves space and reduces the inlet feed particle size prior to drying, optimizing heat transfer and evaporation.
