Centrifuge stay Corn starch separation The process is mainly applied to the following steps:
1. Pretreatment: corn is mixed with water to form corn suspension after cleaning, soaking, peeling and other pretreatment.
2. Rough separation: The centrifuge separates the corn suspension and separates starch from protein, fiber and other impurities by adjusting the centrifuge parameters. Generally, equipment such as disc separator or spiral settler is used for coarse separation.
3. Separation: After rough separation, the starch solution still contains a small amount of impurities, which requires fine separation. At this time, efficient centrifuge or ultracentrifuge can be used for separation to improve the purity of starch.
4. Refining: the starch solution after refined separation needs to be washed, dehydrated, dried and other steps to remove residual impurities and moisture. Centrifuge can be used in dehydration process to realize effective separation of starch and water.
5. Treatment of by-products: some by-products will be produced during the production of corn starch, such as corn residue, protein, etc. Centrifuge can further process these by-products to maximize the use of resources.
When selecting centrifuges, appropriate centrifuge models and parameters should be selected according to the specific process requirements of starch separation, such as production scale, separation effect, equipment investment budget, etc. At the same time, the operation cost, maintenance convenience and compliance with local environmental protection regulations of the equipment shall also be considered.
In a word, centrifuge plays an important role in the corn starch separation process, which helps to improve the purity and quality of corn starch, reduce production costs, and is also of great significance for promoting the development of corn starch production industry.
