Ruicheng hemp chips began in the late Ming and early Qing dynasties and have a history of more than 300 years. According to the "Ruicheng County Records", "Many people have done business in Qin, Jin and Henan when cooking rice with sugar. The west reaches Tongwei, the south reaches Gongluo, and the north catches Finn, which is quite patented. " However, before liberation, this famous historical product was on the verge of extinction. Only a few companies, Xie Shengyong and Tongxin De, only produce two tons a year. After liberation, the party and the government attached importance to the development of local famous products. 1954, the county supply and marketing cooperative established the hemp production and processing department, which was later renamed as the non-staple food processing factory, so that the hemp production continued to expand. 197 1, the cadres and workers of the non-staple food factory designed it themselves, and asked the county Dongfeng machinery factory to assist in manufacturing the hemp chip machine. Since then, the backward manual production technology has been changed, and the work efficiency has been improved by more than ten times. Later, through continuous technological innovation, we improved the packaging, improved the quality and created famous brands.
