Spray drying is a widely adopted process in liquid forming and drying industries. It is especially suitable for producing powdery and granular solid products from solutions, emulsions, suspensions and paste-like liquid raw materials. Therefore, spray drying serves as an ideal process when the finished products need to meet specified standards for particle size distribution, residual moisture content, bulk density and particle morphology.
Working Principle
The high-speed centrifugal spray device for Chinese herbal extract applies centrifugal spray drying technology to the drying of specific materials. A high-speed centrifugal atomizer disperses materials into fine droplets, which make full contact with hot air to complete instantaneous drying and form powdered finished products.
