PPG650 plasma protein powder advection pressure spray drying equipment protease special centrifugal spray dryer drying and material viscosity problems

The drying of protease special centrifugal spray dryer is related to the problem of material viscosity. The drying of food materials such as spray makes the powder particles stick together on the dry wall, resulting in operational problems and low product yield. The sticky behavior is attributed to the presence of low glass transition temperatures in low molecular weight sugars and organic acids. In order to achieve successful drying, various methods such as using high molecular weight drying aids to increase the glass transition temperature of feed mixtures, using low humidity and low temperature conditions to dry the surface, and using dry air and surface modified proteins to encapsulate sugar for drying the cold wall.
