Research on end face sealing characteristics of air classifier - CIP
Abstract: Turbo air classifier was an ultra-fine grading equipment broadly applying in ultrafine classifying industry. However,the leakage phenomenon of coarse powder about classifier with traditional labyrinth seal was not eliminated.Grinding characteristics of raw and parboiled soybean were evaluated in various wet grinding systems, namely, stone grinder, shearing grinder and colloid mill.The duration of grinding had inverse effect on the particle size and direct impact energy consumption in batch grinders.Stone grinder was the least energy efficient and special energy Study on grinding characteristics and quality of soybean milk in ...In order to improve the physiochemical and functional properties of sweet potato dietary fiber, the sweet potato dietary fiber were treated by jet milling and instantaneous high-pressure micro fluidization method, and the composition, physicochemical and functional properties were investigated. The results showed that after treated with jet milling and The effect of two different ultrafine grinding methods on ...
