Abstract
This study was conducted to develop a coating system for producing clean enriched rice. The nutritional components of such as brown rice, white rice, clean white rice, enriched rice of US, black rice of China, and rice with perfume of China, were analyzed and compared. Total protein lipid md minerals in brown rice were higher than those in the other rices. A nutrition premix with lysine, thiamine, niacine, calcium lactate, ferrous lactate, and rice starch was made for enriching white rice. A coating device consisted of a tumbler, two spraying nozzles, a rice mixer, etc was developed with the capacity of 1 ton/h. And far-infrared dryers of batch and continuous types were developed to dry hygienically the wet enriched rice. The percentages of lysine, thiamine, amino acid nitride, and Ca and Fe of the enriched rice samples produced in this study were, respectively, 4, 3, 3. 2, and 10 times higher than those of white rice, respectively.
