How To Produce Sweet Potato Starch And How Does Modern Processing Equipment Of Sweet Potato Starch Work?

Sweet potato starch is widely used and has a long history of processing. However, many of its consumers do not know the machining principle and the main processes of sweet potato starch. So today, I will take you to have a detailed understanding of this.

How To Produce Sweet Potato Starch And How Does Modern Processing Equipment Of Sweet Potato Starch Work?

1. Principle analysis

Sweet potato starch is quite common. Its changing from sweet potato to starch is a complex process.This process is not a chemical process, but a physical separation process.The production of sweet potato starch, is to separate the starch from protein, fiber and other substances. Then the starch can be separated  from starch milk by sedimentation tank or hydrocyclone,with making full use of the characteristic of starch which is insoluble in cold water and denser than water. As a professional sweet potato starch processing equipment, hydrocyclone has been tested by the market, and its separation effect is quite good.

2. Modern sweet potato starch processing

  • After multi-stage of cleaning, the raw materials are cleaner .
  • Secondary sorting and pulverization achieve high crushing rate and sufficient starch dissociation.
  • Three steps of filtration: coarse filtration, fine filtration and micro filtration, help filter impurities well.
  • Removing sand and mud in sections helps ensure the quality.
  • Special swirl structure,which can concentrate and refine starch,improves starch’s precision.
  • After vacuum washing, filtrating and dewatering, the material is fluffy and the water content is small.
  • Drying at low temperature and large air volume helps dry starch well and avoids  its gelatinization effectively.
