Fast drying technology of food products with air energy technology as heat source. Apply advanced energy-saving air energy and heat source, innovate the feeding mode and mechanical structure of drying production line for different materials, optimize drying parameters, and improve drying efficiency and speed.

By modifying the mechanical structure of the flour mixer, the whole tubers flour / whole grain flour is pretreated, and then mixed with wheat flour, so as to achieve the purpose that the traditional flour food processing equipment is partially compatible with tubers flour / whole grain flour.

The raw materials are evenly matured by multistage hot extrusion technology. It can use a variety of whole tubers flour, whole grain flour and other non wheat flour to produce flour products such as macaroni, spaghetti and meal substitute powder.
