As a professional paddy separator machine manufacturer - china-zjlg, our goal is to provide customers with solutions of complete equipment of Paddy Separator Machine processing, for any new product. Our wide range of Paddy Separators can effectively separate brown rice from the grain mixture by using gravity & surface frictional method. We offer paddy separators that have a sieving facility for jam reduction. The machines have stronger transmission system which makes their mechanism better.

Gravity Paddy Separators have unique speed adjustment and material division equipment, which makes the technical performance steadier. These are also fitted with glass cover for dust proof.
A modern rice mill consists of a paddy pre-cleaning system which sieves and aspirators, efficient paddy separators, improved rice whiteners, graders and auxiliary equipment such as elevators, conveyors, automatic weighing machine. Parboiling is a pre-milling most-heat treatment given to raw paddy in order to improve its milling quality, nutritive value, cooking quality and storability. Equipments for parboiling and drying have been installed in some modern rice mills. If parboiling operation is used then, there is an overall increase in total rice recovery of about 6 % over huller mills and 10–20 % reduced percentage of broken (Houston 1972). If different sets of machines are used then all the by-products viz.; husk, bran and broken are obtained in a useable form and this rice milling system may be energy intensive.
It is not clear whether brown rice and white rice were of the same rice variety. Therefore, the results cannot clearly be attributed to the milling process alone in rice whitener. It is possible that the dietary fibre-rich bran fraction in brown rice can continue to serve as a barrier to digestive enzymes, but several other modes of action are also possible. The magnitude of the effect of milling and polishing could also be somewhat dependent on the rice strain and cooking conditions. White rice has a shorter minimum cooking time and higher volume expansion than brown rice, indicating that white rice is more easily hydrated and gelatinised compared with brown rice, and therefore more readily digested resulting in a higher PPG response when cooked under the same conditions.
