The ANDRITZ Gouda drum dryer is unique for turning viscous, pasty, and sticky materials into dried powder or flakes. It is the best choice when the drying process must be as gentle as possible without strong mechanical or thermal impact. Whether you need to process viscous, fluid or heat-sensitive products, steam heating from the inside provides uniform temperature distribution over the outer drum surface, which results in a product of accurate and consistent quality. Food products may benefit especially from the vacuum drum dryer, which enables drying at low temperatures, avoiding damage to heat-sensitive products. Evaporation takes place within seconds, with no risk of oxidation. Enzymes and vitamins are preserved, and proteins are prevented from coagulating.
