How to remove impurities in sweet potato starch production?

In sweet potato starch production process, starch with many impurities and dark colors is a problem for many people. In order to ensure the quality of the final sweet potato starch, removing impurities by sweet potato starch processing machine is necessary. Next i will introduce how to remove impurities in sweet potato starch production by sweet potato starch making machine.

The whole sweet potato starch production process:

In sweet potato starch production of the sweet potato starch processing factory. After the sweet potato raw material is crushed, it needs to be processed by centrifugal sieve, fine fiber sieve, desander, disc separator, hydroclone station. And after dehydration and drying, it is also need to screened by vibrating sieve machine. The final sweet potato starch produced in this way has high whiteness, fineness and good taste. In the whole sweet potato starch production process, there are 4 sections to remove impurities.

The machine to remove impurities in sweet potato starch production

1. Remove the residue - Centrifugal sieve and fine fiber sieve machine to remove impurities in sweet potato starch production

After the sweet potato raw material is crushed, the sweet potato raw material slurry flows into the buffer tank and undergoes acid treatment to prevent browning. The centrifugal sieve and fine fiber sieve machine are mainly used for sieving the crushed sweet potato pulp. Through the gravity of the sweet potato pulp and the low centrifugal force, the fiber components in the sweet potato raw materials are removed, that is, the sweet potato residue.

2. Desand - Desander to remove impurities in sweet potato starch production

Doing Holdings - Henan Jinrui generally configures a desander after the impurity removal of the sweet potato raw material slurry. It's mainly for the purpose of secondary impurity removal, to remove the residual sediment in the cleaning section and the fine fibers remaining after removing the sweet potato residue. The desander can greatly improve the taste of the finished sweet potato starch.

3. Concentration and purification - Disc separator and hydroclone station to remove impurities in sweet potato starch production

The hydroclone station adopts an eighteen-stage full cyclone process, which mainly includes three parts: concentration, recovery and refining. The purpose is to remove the fine fibers, proteins and cell fluids in the sweet potato starch milk and to concentrate and refine the washing starch milk. Doing Holdings - Henan Jinrui is generally equipped with disc separator and hydroclone station to concentrate and purify sweet potato starch milk. Both the disc separator and hydroclone station adopt the principle of centrifugal sedimentation and use the effect of higher centrifugal force to accelerate the sedimentation so that achieve the concentration and purification of sweet potato starch milk.

4. Screening - Vibrating sieve machine to remove impurities in sweet potato starch production

After the sweet potato starch milk is dehydrated and dried, it needs to be sieved and then will to be packaged and processed. The role of the vibrating sieve machine is to sift the dried sweet potato starch through a variety of different meshes, the sweet potato starch of different particle sizes can be continuously separated well to meet various needs.

In the process of sweet potato starch production, after removing impurities, the finished sweet potato starch not only has high fineness and good taste, but also the whiteness can reach the market requirements, good selling, and high economic returns.
