Rice milling process is a series of operations to remove of rice hulls and barns from paddy grains to produce milled white rice. Rice forms the basic primary processed product obtained from paddy and this is further processed for obtaining various secondary and tertiary products. (Paddy in its raw form cannot be consumed by human beings.

Industrial hammer mills are employed in particle reduction applications for processing material. Though machine designs vary, the basic hammer mill working principle remains the same—uniform size reduction of aggregate raw material is achieved by repeated blows with hammers mounted to a rotating shaft. Whether coffee beans or titanium, hammer ...

The basic objective of a rice milling system is to remove the husk and the bran layers, and produce an edible, white rice kernel that is sufficiently milled and free of impurities. Depending on the requirements of the customer, the rice should have a minimum number of broken kernels. The rice kernel composition

Hammer mill works on the principle of impact between rapidly moving hammers mounted on a motor and the material to be milled. As the hammers revolve at peripheral speeds reaching 10, they direct themselves towards the radial directions and hit the dropping feed breaking its particles into small fragments. Construction of Hammer Mill:

Thresher is a rice seed thresher. Threshing is an integral part of the process in rice postharvest management, in which the rice that has been harvested is threshed to separate the grains from the rice straw. The working principles of the thresher are by bearing the rice straws so that the grains will fall off. One of the main

16. MILLING SYSTEMS A rice milling system can be a simple one or two step process, or a multi stage process. In a one step milling process, husk and bran removal are done pass and milled or white rice is produced directly out of paddy. In a two step process, removing husk and removing bran are done separately, and brown rice is produced as an ...
