Title: Device for taking out finished rice in shaking separator
Inventor: YAMAMOTO SOICHI
IPC: B07B13/16
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent the unhulled rice from mixing with finished rice by forming an auxiliary take-out aperture at a position close to the shape collection side of a hulled rice partitioning plate without setting a space in between, and returning the opains taken out at the auxiliary take-out aperture to the supply side of a shake separating plate. SOLUTION: This finished rice take out device has an auxiliary take-out aperture 15 formed at a position close to the hulled rice take-out aperture 9 side of a hulled rice partitioning plate 7 without setting a space in between so that grains near the hulled rice partitioning plate 7 can be taken out. The grains taken out through the aperture 15 are returned to a mixed rice screw 13 through a take out hopper 17 and then are returned to the supply side of a shake separating plate. Consequently, the unhulled rice (a) discharged at a position close to the make collection side of the hulled rice partitioning plate 7 is discharged to the aperture 15. Therefore, it is possible to prevent the unhulled rice (a) from mixing with finished rice, even when the unhulled rice (a) is present in the hulled rice.  In addition, the lower part of the take-out hopper 17 is equipped with a sample pickup aperture 18, a return aperture 19 and a switching value 20 for these apertures 18, 19. Thus it is possible to confirm mixing state of the unhulled rice (a) by changing over the switching valve 20.
