The respective sorting cylinders 1... and the cleaning bodies 4 are fitted and mounted respectively.
... are connected to the electric motor 8 via the rotation mechanism 30 and rotated, thereby forming a multi-stage grain size sorter.

Next, the particle size selection effect will be explained in detail. When large and small mixed grains (for example, brown rice mixed with immature grains, etc.) are put into the evenly dividing feeding device 10 and the device is started, the mixed grains in the feeding device 10 flow down evenly into each grain. The material is supplied from the supply hopper 6 into each porous wall sorting tube 2.

The porous wall cylinder 2 (see Fig. 5) is designed to remove grains from the upper end of the grain layer A while the grain layer A formed by the supplied grains is placed on top of the grain layer A in the direction shown by the arrow by the 20 rotations of the sorting cylinder. Certain grains flow like an avalanche and fall into a predetermined sorting area B on the opposite side of the porous wall, and when the grains flow, fine grains such as immature grains with a small grain size move through the channels provided on the porous wall due to centrifugal force. The fine particles are discharged from the hole 3 and flowed down inside the cylinder, and the fine particles are discharged from the fine particle discharge tube 9 provided at the bottom.
The particles are discharged outside the machine from the
Grain flow channel 2 provided on the front wall frame 13 surface with the inside flowing toward the discharge side
8 and is discharged to the outside of the machine via the sized discharge port 5.

In the above sorting action, each through hole 3 of the porous wall sorting tube 2
Particles that are approximately the same size as the through holes fit into the through holes in a wedge shape due to the avalanche-like flow action described above and become clogged. The clogged area will be cleaned by removing the stuck particles.

Moreover, when disassembling the particle size sorter, each member can be easily disassembled by performing the reverse process of the above-mentioned assembly operation. Note that the porous wall sorting cylinder of the present invention has a cylindrical body,
The cleaning body is formed into a polygonal cylinder or the like, and the cleaning body is formed into a blade wheel or blade piece using an elastic material such as rubber, plastic, or plastic.

Since the opening/closing plate portions 22 are provided on the side wall frame 23 on which the cleaning body 4 is mounted, it is possible to simultaneously check the operating state of the cleaning body 4 and the clogging state of the sorting tube 2, and also to easily remove and install the cleaning body 4. In addition, a fine particle flow lower plate 39 is installed on the side of the sorting tube 2.
is connected to the flow grain plate 20 of the side wall frame 23 and the fine grain discharge port 40 at the upper part, so that the fine grains extracted from the through holes of the porous wall are transported through the flow process in each machine frame 1. The particles smoothly flow down and are discharged from the fine particle discharge pipe 9 to the outside of the machine.

FIGS. 7 and 8 illustrate another embodiment in which a bearing 38 is attached to a supporting horizontal rod 37 provided inside the front wall frame 13 to pivotally support the rotating shaft 35 of the sorting cylinder 2. Since the upper part of the horizontal rod 37 is covered with an inclined cover plate 42, the sorted grains flowing down from the discharge end of the upper sorting tube 2 may come into contact with the horizontal rod 37, the bearing 36, etc., or be scattered and discarded into the sorting tube. 2, and it is possible to prevent the sized particles from being crushed.

FIG. 9 is a front view of a plurality of multi-stage grain size sorters, in which the grain size discharge ports 5 of each sorting cylinder 2 are removably connected to the grain size flow lower cylinder 43.
..., and the flow tube 43 is formed so that it can be connected or detached in conjunction with the opening/closing operation of the opening/closing door 31 provided on the peripheral wall frame 27 of the front wall frame 13.
