This production line is developed for the nutrient content of rice lost in the traditional rice milling process. Rice and its by-products can be made into highly value-added products through extrusion processes. In this process, broken rice and rice bran can be reused. The entire production process is simple and easy to operate: After crushing, broken rice is mixed with a certain amount of water, oil, etc.. At a certain temperature, the raw material is ripened in the extruder, and then it is extruded by the mold to form a rice shape. Finally, the reconstructed rice grains are dried at low temperatures. This extrusion technique effectively avoids the loss of nutrients and thus becomes a nutrient-rich fortified rice.
