What is the starch yield rate of sweet potatoes? How to increase the starch yield rate of sweet potatoes?

Industry news:2023/08/24

The starch yield of sweet potatoes is a matter of concern for sweet potato starch processing manufacturers. The starch yield of sweet potatoes is related to the profitability of sweet potato starch processing plants. What is the starch yield rate of sweet potatoes? In fact, the starch production rate of sweet potatoes is related to the freshness, variety and processing technology of sweet potato starch. If you choose starchy varieties, sweet potatoes with high freshness, and adopt advanced and perfect processing methods, the starch production rate of sweet potatoes will be higher!

1. What is the starch yield of sweet potatoes?

Different varieties of sweet potatoes have different starch content. For example, red-skinned and white-cored starchy sweet potatoes have higher starch content than ordinary red-cored sweet potatoes, so red-skinned and white-cored sweet potatoes are a better choice for processing starch. Freshly harvested sweet potatoes are processed immediately, and the flour extraction rate can reach as high as 35%. However, if the sweet potatoes are stored for a long time, more than 20 days, the starch in the sweet potatoes will be converted into sugar, and the flour extraction rate will drop below 20%. The normal sweet potato starch on the market will produce 1 ton of starch after processing 5 tons of sweet potatoes, and the powder yield of sweet potato starch is about 5:1.

2. How to increase the starch yield rate of sweet potatoes?

1. Choose starchy sweet potatoes. Choose starch-type sweet potatoes to process into starch, and the amount of sweet potato starch obtained will be higher.

2. Choose fresh sweet potatoes. The flour extraction rate of freshly harvested sweet potatoes is relatively high. You should choose freshly harvested sweet potatoes, and the storage time should not exceed half a month, otherwise the starch content will gradually decrease, so the flour extraction rate and extraction rate of starch will be lower. .

3. Choose a new starch extraction method. With the continuous advancement of science and technology, the extraction method of sweet potato starch is also constantly improving. The traditional starch extraction method mainly uses the natural sedimentation in the sedimentation tank and the Physalis method to extract sweet potato starch. The new method is to use European wet processing technology to process sweet potato starch, fully automatic 18-stage cyclone to refine and extract starch, and extract sweet potato starch. The rate will be higher and the quality of starch will be better.

To sum up, fresh starchy sweet potatoes should be selected for processing, and a new method of extracting sweet potato starch should be selected to make the processing of sweet potato starch have a higher powder yield! If you want to make the starch extraction rate of sweet potato higher, Jinrui is your good choice. The sweet potato starch processing equipment manufactured by Jinrui can extract more than 94% of sweet potato starch, allowing you to efficiently produce sweet potato starch!
