PPG650 Plasma Protein Powder Horizontal Pressure Spray Drying Machine

The centrifugal spray dryer for protease is related to the sticking issue of the material during drying. In the drying of these food materials by spray, the powder particles stick together, forming a layer on the drying wall, causing operational problems and low yield of the product. The sticky behavior is attributed to the presence of low molecular weight sugars and organic acids with low glass transition temperatures. To achieve successful drying, various methods such as using drying aids with higher molecular weights to increase the glass transition temperature of the feed, drying under low humidity and low temperature conditions, scraping the dried surface, and using dried air and surface-modified proteins for encapsulating the sugar drying cooling wall can be employed.
