Rice process line adopts brokený riceý as main ingredient, and some other vitamin and mineral as part of ingredient. The material is extruded into rice shape by the twin-screw extruder, and dried in a rotaryý dryer to needed moisture content. The extruding technique makes it possible to strengthen and solidify the micronutrient in the rice. This artificial rice can be mixed with natural rice prior to cooking as usual. When cooking is finished, its grains are not broken and there is no difference between the artificial rice and the natural one in viscosity, elasticity and taste.
