Paddy separator is used for separating the rice from the mix stream of paddy and brown rice. Industrial Paddy Separator Machine is an ideal equipment for separating pure brown rice from the grain mixture by taking advantage for the difference of the gravity and surface frictional coefficient between brown rice and paddy, it is particuarly suitable for mixed grain and effective in improving the purity of brown rice and in increasing output. Separator with driving mechanism which is developed in our works is characterized by its firm structure, stable operation, convenient adjustment and reliable quality.
