During the Yangshao Culture period from 5000 to 3000 BC, China had stone grinding discs and grinding rods for grain processing. The invention of the mortar and mortar has a history of about 3000 years. In the Western Han dynasty, foot-steel, animal-power and water-steel were invented successively, and there were fans for grain cleaning. The Jin Dynasty Du Yu produced a "connected machine" that was driven by hydraulic power to process grain at the same time. At the end of the 16th century, China's rice milling technology and machinery were initially perfected. After the introduction of horizontal iron roller rice milling machine and vertical sand mortar rice milling machine at the end of the 19th century, grain processing machinery further developed. Europe used wind-driven milling in the 12th century. Hungary created a steel roller mill in the 18th century, but it was not used for large-scale grain processing until 1870.
