How to increase potato starch yield?

Potato starch is a powder made from potatoes that plays an important role in both the food and non-food industries. For potato starch production plants, the greater the potato starch output, the greater the economic benefits. Therefore, more and more people regard the low yield of potato starch as the top priority for optimizing potato starch production enterprises. So how can we improve the extraction rate of potato starch?

As far as the current production situation is concerned, improving the yield of potato starch can be analyzed from two aspects: raw potatoes and potato starch processing machinery.

1. Fresh potatoes with good fresh quality and high starch content can effectively improve the starch extraction rate.

In the process of starch processing, the raw material is an important factor affecting the starch yield. The factors that influence our choice are mainly the variety, storage period and quality of the raw material. Different types of raw potatoes contain different levels of potato starch. Only by selecting raw potatoes with high starch content can the extractable rate of potato starch be guaranteed. 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 increasing stacking time. Therefore, fresh potatoes with good quality and high starch content must be selected to increase the yield of potato starch.

2. The introduction of mature and advanced potato starch processing machinery will help increase starch yield.

With good quality raw potatoes and high starch content, will the yield of potato starch be high? The answer is obviously no, because without advanced and efficient potato starch processing machinery, everything you have prepared before will be in vain. Henan Jinrui potato starch processing machinery adopts mature European processing technology and is designed and manufactured according to the characteristics of raw potatoes.

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

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

(2) The clogging degree of the centrifugal sieve will also affect the yield of potato starch. The protein and pectin in the starch slurry absorb water, and the resulting gel can easily clog the centrifugal sieve. In severe cases, more than 60% of the screen will be blocked, affecting the separation of starch. Therefore, we need to clean the screen with 2% neutral salt solution to dissolve the gel and improve the yield of potato starch.

If you are struggling with how to increase potato starch yield, this article will answer your questions. In addition to the raw potatoes and potato starch processing machinery mentioned above, factors such as the configuration of the potato starch processing machinery will also affect the yield of potato starch. Therefore, it is necessary to consult an experienced expert on how to choose potato starch processing machinery that suits your needs.
