International ClassesB02B 003/00B02B 003/04 B02B 003/06 Foreign Application Priority Data1991-12-27 JPAbstractA rice-cleaning machine has a flowing-down friction type rice-cleaning chamber (18) formed around the lower portion of a main vertical rotary shaft (10) a grain sending chamber (79) formed around an upper portion of the main shaft (10) for forcibly sending grains to the rice-cleaning chamber (18), and a rising-up abrasion type rice-cleaning chamber (44) formed around the grain sending chamber (79). Rice-cleaning rolls (15) and (38) of the rice-cleaning chambers (18) and (44) are independently driven to rotate. A grain overflow port at an upper portion of the abrasion cleaning chamber (44) and a grain flowing-in port at an upper portion of the grain sending chamber (79) are communicated through by a connection passage (61). A rice grain supply apparatus consisting of a vertical cylinder body (46) and a vertical spiral (49) are connected to a side portion of the abrasion chamber (44).Field of SearchWith disjoining hull from grainBy projecting grain against surface Plural hulling zones Including coacting, relatively rotating imperforated surfaces Having plural, rotary, multiperforated surfaces And varying flow of grain Directing gas adjacent hulling zone With screen to separate products 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 Serial zones Axially spaces zones With interior partition By rotating surface Including a screw-threaded mounting Deformable hulling surface Radial hulling surface From plant material Outer covering, e.g., shell, husk, etc. By abrading Material thrown against perforated surface by centrifugal force And auxiliary imperforate surface (e.g., breakerplate) Outer peripheral comminuting face | |
