Rice Milling Poonam Dhankhar M.Tech (Food tech), G.J .U.S & T, Hissar, Abstract: - The Rice milling is the process that helps in removal of hulls and bran's from paddy grains to produce polished rice. Rice is rich in genetic diversity with thousands of varieties grown throughout the world. Rice has been one of man's most important foods.

Milling is a crucial step in post-production of rice. 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.
