Rice Milling and Drying Information | Producers Rice Mill

Milling of Rice During the milling stage the rice moves through a multifaceted process. When rice arrives at the mill, it is ushered through a series of sorting machines, separating the kernels, encased in an inedible hull or husk, from any debris. The rough rice passes through "sheller" machines that remove the hull. What remains is brown rice, with the bran layers still surrounding the kernel.

through the wall of the dryer from a hot gas flowing outside the wall or by radiation. Dryers exposing the solids to a hot surface with which the solid is in contact are called adiabatic or direct dryers, while when heat is transferred from an external medium it is known as non-adiabatic or indirect dryers. Dryers heated by dielectric, radiant or
