What are the methods and measures to improve the extraction rate of potato starch?

FAQ / Leave Message / Chat Online Jul 06, 2022

Potato starch is a powder made from potatoes, which plays a significant role in both the food industry and the non-food industry. For potato starch production enterprises, the larger the output of potato starch, the greater the economic benefits. Therefore, the low output of potato starch has become a difficult problem for potato starch manufacturers. How to improve the extraction rate of potato starch?

As far as the current technology is concerned, improving the yield of potato starch can be analyzed in terms of raw potatoes and potato starch processing machine.

1.Choose fresh potatoes with good quality and high starch content

In the process of starch processing, the raw material is an important factor affecting the starch yield, which can also be divided into variety, stacking period and quality of raw materials. Different types of raw potato contain different levels of potato starch. Only by selecting raw potato with high starch content can the extractable rate of potato starch be ensured. The quality of potato raw materials also affects the yield of potato starch. If there are too many impurities in fresh potatoes or too many damaged potatoes, it will have a great impact on the yield of potato starch. In addition, the yield of potato starch decreased with the increase of stacking time. Therefore, it is necessary to choose raw potatoes with good quality and high starch content in order to increase the yield of potato starch.

2.Introduce mature and advanced potato starch processing machine

With good quality raw potatoes and high starch content, will the yield of potato starch be high? The answer is obviously not, because if there is no advanced and efficient potato starch processing machine, everything you have prepared before will be in vain. Henan jinrui's potato starch processing machine adopts mature European processing technology, which is designed and manufactured according to the characteristics of raw potatoes.

In addition, it should be noted that the following two aspects affect starch yield to a certain extent.

(1)The design of grinding and crushing can effectively improve the crushing of potato raw materials, so as to release the bound starch as much as possible and improve the extraction rate of potato starch.

(2)The degree of blockage of the centrifuge sieve will also affect the yield of potato starch. The protein and pectin in the starch slurry will absorb water, and the formed gel can easily block the mesh of the centrifuge sieve. In severe cases, more than 60% of the meshes are blocked, which affects the separation of starch. Therefore, we need to use a 2% neutral salt solution to clean the screen, dissolve the gel, and increase potato starch yield.

After reading this article, you can learn two main ways to increase potato starch yield. In addition, factors such as the configuration of potato starch processing machine will also affect the output of potato starch. Therefore, it is necessary to consult an experienced specialist before you design a plan to increase potato starch yield. If you need it, Henan jinrui can provide you with a complete set of potato starch processing machine.
