Causes of excessive impurities during the extraction of potato starch

Causes of excessive impurities during the extraction of potato starch

What are the reasons for the excessive impurities in the finished potato starch? Only by understanding the reasons first can we do the right thing to promote our business.

The reasons for the excessive impurities in the potato starch extraction process can be analyzed from three aspects. They are the raw material cleaning area, potato residue removal area and sand removal area.

Except sand area: In addition to the clean area of the raw material of the potato starch product, the sand area may also cause excessive impurities during the extraction of potato starch. Therefore, in order to improve the quality of the finished potato starch and remove the sludge in the potato starch, the potato starch extraction process should be equipped with a de-sander, and used in conjunction with other potato starch pulping machines to remove impurities.

In addition to the above three reasons, the reason for the excessive impurities in the potato starch extraction process may be processing technology. In the process of using non-sealed processing technology to produce potato starch, it is easily affected by environmental factors, causing potato starch to turn brown or adulterate dust. Therefore, it is necessary to choose potato starch production and processing equipment using sealed processing technology.


Raw material cleaning part: Potato raw material cleaning is one of the important parts that affect the quality of the final potato starch. The reason for the excessive impurities in the potato starch extraction process is that the cleaning process is not strictly controlled and the cleaning strength is not enough, which will increase the amount of sediment in the starch. Doing Holdings-Henan Jinrui uses 2 sets of potato cakes in the cleaning part, dry sieve and rotary washing machine


Powder production equipment. In the potato starch extraction process, the effect of removing impurities is obvious, and it also has the function of peeling.


Potato residue removal zone: The fiber component in the potato raw material slurry will cause the final potato starch to taste bad. Therefore, it is important to remove the fiber from the potato raw material slurry. When sieving potato residues, some manufacturers use a smaller mesh size, which will cause a large amount of fine residues (crude fibers) to leak into the sieve together with starch milk, and use the same coarse


After the second sediment is filtered through a sieve, or after no secondary filtration is used at all, the fine residue is easily mixed with the small granular starch, resulting in an increase in the content of impurities such as crude fiber in the starch. Currently, the potato starch processing machine designed by Doing Holdings (Henan Jinrui) uses two types of potato starch production and processing equipment, namely, high-screen centrifugal screen and fine fiber screen.


Used to remove potato residue and slag. good results.

High-quality potato starch is the first choice of customers. Analyzing the causes of excessive impurities in the potato starch extraction process, and then solving these problems, can greatly improve economic benefits.
