Q: What are the main processes that happen at a rice mill?

Cleaning and Sorting: The process begins with cleaning the paddy rice to remove impurities such as dust, stones and husks. Specialized equipment like paddy cleaners and separators are used to achieve this. The cleaned rice is then sorted to remove any remaining impurities or damaged grains. Husking: Next, the husk (outer layer) of the paddy rice is removed through a process called husking or dehusking. This is typically done using a machine called a rice huller or dehusker. The result is brown rice, which still has the bran and germ layers intact. Milling: The brown rice is further processed in the milling stage, where the bran and germ layers are removed, leaving behind polished white rice. The milling process involves passing the brown rice through abrasive surfaces or rollers to strip off the bran layers. The resulting white rice is then separated based on size and quality using grading machines. Sorting and Packaging: The milled rice is inspected and sorted based on quality, size and other criteria. Advanced optical sorting machines may be used to identify and remove any remaining impurities, discoloured grains or foreign materials. The sorted rice is then packaged in bags or other containers for distribution and sale. Quality Control: Rice mills implement quality control measures to ensure that the milled rice meets established standards for quality, appearance and nutritional value. This includes regular testing for moisture content, broken grains, foreign matter and other parameters. Storage and Distribution: After milling and packaging, the rice is stored in appropriate conditions to maintain its quality and prevent spoilage. Rice mills may have storage facilities to store the milled rice before it is distributed to wholesalers, retailers or directly to consumers.

Question 1

What is a rice mill?

Accepted Answer

A rice mill is a facility or establishment that processes paddy rice (unhusked rice) into milled rice, ready for consumption or further processing. Rice mills play a crucial role in the rice production and supply chain by transforming raw rice into the finished product.

Question 3

What are the by products of a rice mill?

Accepted Answer

Rice mills also produce by-products such as rice bran and rice husk. Rice bran can be used in various applications, including animal feed, oil extraction or in the production of rice bran-based products. Rice husk, a by-product of the dehusking process, can be utilized as a source of energy, for example, as fuel for boilers or biomass power generation.
