Abstract
A milling roll for use in a rice milling machine for removing the bran coating from the exterior surface of the rice kernels, in which the rice kernels are caused to rub or roll against each other rather than between relatively moving surfaces. The milling roll is generally cylindrical in construction with spaced baffles oriented at particular angular positions so that rice kernels will enter the milling roll between certain of the adjacent baffles from the periphery of the rotating roll toward the center thereof where the rice kernels will be caused to rub against each other as they work in and out and are ultimately discharged between adjacent baffles peripherally of the milling roll for discharge from the rice milling machine through the usual rice outlet or discharge spout past the usual pressure plate control mechanism.
Claims5
In a rice rolling machine having a frame supporting a stationary screen provided with a peripheral screen wall, a rotatable main shaft disposed centrally of said screen, an inlet at one end of the screen and an outlet at the other end thereof, a milling roll comprising a pair of longitudinally spaced end plates, a plurality of longitudinally elongated, spaced baffle plates rigidly interconnecting said end plates with the space between the baffle plates being open, each of said end plates being annular and including a large central opening receiving the main shaft of the rice milling machine, said baffle plates including a plurality of equally and circumferentially spaced first angled baffles having a radially inwardly inclined surface and an equal number of circumferentially spaced second arcuately curved baffles having a radially outwardly inclined surface, said first angled baffles serving to move rice kernels radially inwardly from the periphery of the milling roll and screen toward the main shaft during rotation of the milling roll and the second arcuately curved baffles serving to move rice kernels radially outwardly of the milling roll during rotation thereby rubbing the rice kernels together for removing the bran coating.
