Centrifugal screens can be used in the screening process of starch processing to separate starch slurry and residue, remove fibers, raw material residues, etc. Common raw materials that can be processed include sweet potatoes, potatoes, cassava, taro, kudzu root, wheat, and corn. In the process of starch processing, the use of centrifugal screens for slurry and residue separation can be efficiently screened, with advantages such as good screening effect and high efficiency.
Working principle of centrifugal screen:
In the process of starch processing, the crushed sweet potatoes, potatoes, cassava, taro, kudzu root, wheat, corn and other raw materials form raw material slurry, which contains mixed substances such as starch, fiber, pectin, and protein. The raw material slurry is pumped into the bottom of the starch centrifugal screen by a pump. The screen basket in the starch centrifugal screen rotates at high speed, and the starch slurry enters the surface of the screen basket. Due to the different sizes and gravity of impurities and starch particles, when the screen basket rotates at high speed, under the action of centrifugal force and gravity, the fiber impurities and small starch particles enter different pipes respectively, thereby achieving the purpose of separating starch and impurities. And the centrifugal screen is generally configured with 4-5 levels, and the raw material slurry is filtered through 4-5 levels of centrifugal screens, and the screening effect is good.
1. High fiber separation efficiency:
The centrifugal screen can effectively separate solid particles and liquid in starch slurry through the centrifugal force generated by high-speed rotation, thereby improving the separation efficiency. Compared with the traditional cloth-hanging extrusion pulp-slag separation, the centrifugal type can achieve continuous operation without frequent shutdown, which is suitable for large-scale starch processing and production.
2. Good screening effect
Starch centrifugal screens are usually equipped with 4-5-stage centrifugal screens, which can effectively remove fiber impurities in starch slurry. They are usually equipped with automatic control systems, which can realize automatic feeding and automatic slag discharge, reduce manual operations, and ensure the stable effect of starch screening.
Starch centrifugal screens are used in starch processing pulp-slag separation to improve the production efficiency of starch processing and the quality of starch products.
