High demand for sweet potato starch and high efficiency in timely processing
Sweet potato starch plays a more and more important role in people's daily diet. At present, potato chemical products have become the main raw materials of lactic acid, citric acid, disposable tableware and degraded agricultural plastic film and other chemical products. It is understood that the current price of refined sweet potato starch is nearly 10% higher than that of last year, and the reason for this price trend is undoubtedly the gap between supply and demand of sweet potato starch. Relevant data show that at present, the demand for sweet potato starch in the domestic market alone is more than 1 million tons, while the production is far less than this number.

Starch produced by fresh sweet potato generally belongs to manual production in rural areas, while sweet potato starch factories mostly use dried sweet potato as starch raw material, so it belongs to industrial production. 1. The technological process of producing starch from fresh sweet potato is as follows: raw material selection-washing-crushing-grinding and filtration-mixing-skimming and sitting-skimming-pulping-drying. The production process is as follows: (1) selection of raw materials: due to different sweet potato varieties, their quality and starch content are also different, even if the same variety is in different producing areas.
