The primary processed product of sweet potatoes is starch, there are over 500 types of starch reprocesses. It is an important raw material in industries such as chemical, food, medicine, with a high demand. Dried potatoes can be used to produce alcohol, which is also an important chemical raw material backup energy. In the future, during periods of energy shortage, alcohol can be used as a substitute for car fuel. Therefore, the development of sweet potato industrial processing has broad prospects.

With the development of the breeding industry, the production of formula feed mainly composed of sweet potatoes is also increasing year by year. In the 1990s, Anhui Province produced hundreds of thousands of tons of sweet potato components in formula feed every year. At the same time, the amount of stem leaf silage, fresh storage of potato residue, fermented feed will also increase year by year.

Although the history of using sweet potatoes to process vermicelli in rural areas of China can be considered long, traditional techniques manual operations are often used, resulting in low efficiency, high labor intensity, poor color, impurities, quality of vermicelli, making it difficult to compete with vermicelli in the international market. Moreover, some profit oriented producers, in order to brighten whiten the surface of their fans, arbitrarily add prohibited substances during the processing of fans.

In order to solve these problems, China has introduced large-scale mechanized complete sets of equipment to varying degrees in sweet potato production processing zones, accelerating the industrial production of starch vermicelli. Through the establishment of joint ventures sole proprietorships to introduce management experience, the quality output of sweet potato vermicelli products in China have been significantly improved, many well-known brands have been created, which are deeply loved by consumers in various parts of China, some are also exported to foreign countries, Becoming the main source of local export earnings.
