This process line is one of the newly developed double-screw extruding techniques of our company. The traditional stir-fry handiwork has low efficient and less usable raw materials, and its sanitation and quality are difficult to control. The double-screw extruding technique makes up those lacknesses. It not only can process grain materials, like buckwheat, oats, etc. but strengthen the nutrients to produce multi-functional nutritional healthy food, such as slimming grain powder, buckwheat powder, black sesame paste, red chinese date thick soup, etc.
