Rice Processing

The basic goal of industrial rice milling is transforming paddy rice into white rice giving it a good appearance and selecting the best quality grain for human consumption.After rice is harvested it has a non-edible husk or hull surrounding the kernel. At the rice mill, all stalks and other foreign material are removed from the rough rice by a variety of specialized machinery. Cleaning : At these stage foreign objects, such as hey, stone and tree stump are removed. Hulling : Hulling consists of rubbing excessive husks off the cleaned paddy. After removal of husk, brown rice is separated from the husks though ventilation process and mechanical equipment leaving pure brown rice available for milling. Polishing : This stage is responsible for smoothing and brightening the surface of rice grain by a roll or series of rolls. Grading : Milled rice are a mixture of different sizes: whole grain, head rice, and broken rice. The rice of different sizes is separated by a sieve grader. The process includes several sizing techniques. Sorting This Process removes defective rice, such as discolored rice, yellows, immature (green), chalky, peck and red rice. Foreign bodies like seeds, glass and stones also removed in this process. It adds value to white rice to ensure that only the cleanest rice is passed. Packaging / Storage : The finished rice is packed and stored in individual bags according to the grades. The rice is finally ready for delivery to the customers.
