Abstract

The invention discloses a method for producing sweet potato starch and treating sweet potato dregs and belongs to the field of food processing. The method comprises the following steps: delivery, washing, pulverization, slurry-dreg separation (filter-pressing of sweet potato dreg, pulverization of sweet potato dreg, drying and packaging of sweet potato dreg), filtration of starch stock, separation, dehydration of starch milk, drying of sweet potato starch, gas-powder separation, sieving, packaging of sweet potato starch, and fashioning. The method has the advantages of high yield of sweet potato starch, high resource utilization rate and no environmental pollution. The method is used for the production of starch from sweet potatoes with different starch contents, as well as starch-containing tuber crops such as potato, taro and Kudzuvine root. The method is implemented by physical process without using any chemicals, so that the sweet potato starch is free of harmful chemical residues.

Description

Technical field [0001] The invention relates to the field of food processing, in particular to a process for producing sweet potato starch and treating potato dregs. Background technique [0002] Sweet potato is a high-yield and drought-tolerant dry food crop. It has always been used as supplementary food and livestock feed in times of famine. Sweet potatoes in normal years are mainly used to process sweet potato starch, and then processed from sweet potato starch into potato flour chips, potato vermicelli, and potato chips. Vermicelli and other foods, or sweet potato starch as industrial raw materials. The production process of sweet potato starch is actually a physical separation process, which is to separate the cellulose, protein, inorganic salt and other substances in the raw material from the starch. In the prior art, there are two main types of sweet potato starch production processes, one is the mechanized production method, and its process flow is: conveying→cleani...
