Fortified rice kernels (FRK) are produced from this mixture using an extruder machine. The kernels resemble rice grains. FRK is added to non-fortified rice in ratio ranging from 1:50 to 1: 200 ( ideal is 1:100) resulting in fortified rice nearly identical to traditional rice in aroma, taste, and texture

Nutritional Rice Production Line is an another innovative application of screw extrusion technology. The production line not only can use rice powder, corn powder etc as raw material, but also can add various nutritional elements into raw material, such as vitamins, mineral and dietary fibre. Then by twin screw extruder pelleting to produce nutrition redouble rice. The technology not only achieve to keep common rice original elements, but also supplement and redouble nutritional body needs element.
