International ClassesA23L 001/00B02B 003/00 B02B 003/04 B02B 003/06 Foreign Application Priority Data2000-07-05 JPAbstractA rice polisher for polishing rice, which is a preprocess necessary for producing pre-white rice having a favorable taste by using a small amount of water, a pre-polished rice producing apparatus that uses the rice polisher, a leveling device capable of uniformly leveling grains, and a pre-polished rice producing facility. The rice polisher includes a grain-lifting spiral for transporting white rice above from below, a water-pouring port for pouring polishing water, the water-pouring port being disposed at a head portion, a discharge port for discharging the white rice, the discharge port being disposed at the head portion, and a rice-polishing roll for polishing rice by agitating together with the polishing water poured from the water-pouring port the white rice pressurized by transportation by the grain-lifting spiral, with the polisher discharging from the discharge port the white rice that has been polished.Field of SearchBy applying fluidBy projecting grain against surface Plural hulling zones Including coacting, relatively rotating imperforated surfaces Having plural, rotary, multiperforated surfaces With means to vary spacing between hulling surfaces And varying flow of grain Directing gas adjacent hulling zone Internally and externally of hulling zone By valved gas passages With screen to separate products Interrelated drive means for huller and gas-move Gas-mover integral with huller Gas-mover coaxially separated from huller By rotating surface Adjustably or yieldably mounted hulling surface Including a screw-threaded mounting Deformable hulling surface With additional rotating surface Radial hulling surface Grain hulling With means to segregate diverse materials By hulling means Moving perforated surface With nonperforated hulling surface area Cylindrical or conical perforated enclosure With axially extending nonperforated hulling portion With additional hulling surface characteristics on enclosure Enclosing a rotating, yieldably hulling element With mechanism to feed or discharge material Integral with moving hulling member With discharge control By plural hulling zones Material thrown against perforated surface by centrifugal force And auxiliary imperforate surface (e.g., breakerplate) Outer peripheral comminuting face From plant material Outer covering, e.g., shell, husk, etc. By abrading | |
