Drying Technologies
Drying technologies convert wet protein products into stable powders or dried forms for storage, transport, and further processing. Key methods include spray drying, freeze drying (lyophilization), drum drying, and fluidized bed drying. The choice of drying method significantly impacts product quality, functionality, and cost.
Process Overview
- 1Feed Preparation: Concentrate and homogenize the liquid feed
- 2Atomization: Break liquid into fine droplets (spray drying)
- 3Drying: Remove moisture via hot air, vacuum, or sublimation
- 4Collection: Gather dried powder or product
- 5Packaging: Pack under controlled atmosphere
