The specific operation in the above embodiment will be described below. The raw rice put into the receiving hopper 2 is supplied to the roughing machine 3 through the graining machine 4, and the cut ears and impurities are sorted into the trash container 5A, and the immature grains are sorted into the immature grain receiving trough 5B. Is accommodated. The paddy from which impurities and immature paddies have been removed is fed to the weighing machine 6 via the three-way switching valve 45 and the graining machine 42.
After being supplied and weighed, they are conveyed through the graining machines 7 and 8, the two-way switching valve 9 and the carry-in belt conveyor 11, and are distributed and charged into the respective receiving tanks 15 by the three-way switching valve 12. .

The paddy temporarily stored in the receiving tank 15 is
Although the alteration is prevented by receiving the ventilation by the blower 16, when the paddy is filled in an appropriate amount, it flows out from the discharge port 20 onto the discharge belt conveyor 25, and the graining machine 26 and the two-way switching valve 27
Is supplied to the dryer 28 through The paddy flowing down in the dryer 28 is subjected to hot air from the furnace 30 for generating hot air and the blower 29 to remove moisture from the rice husk on the surface. The rice hulls having dried to a certain extent through the dryer 28 are thrown into the vacant tempering tanks 17 and 18 by a graining machine 31 and a carry-in conveyor (flow conveyor or the like) 32. While being left in the tempering tanks 17 and 18 for several hours, the moisture of the brown rice migrates to the rice hulls and equilibrates (temper), and at this time flows out of the outlets 21 and 23 and is again dried.
Is subjected to a drying action, and the paddy that has passed through the dryer 28 is transported to the tempering tank 18.

Drying is carried out in this manner, and when the water reaches the moisture that does not alter the quality of the paddy, for example, 18%, the paddy is charged into the storage silo 19 and stored until the receiving period of the harvesting period ends. Then, when the receiving period ends, the paddy in each storage silo 19 is sequentially discharged, and repeatedly subjected to the drying operation by the dryer 28 and the refining operation by the tempering tanks 17 and 18 to be dried to, for example, 15%.

When the drying is completed, the finished paddy is sold to the government through a selection process. That is, the paddy flowing out from the discharge port 22 of the storage silo 19 containing the required paddy is supplied to the roughing machine 3 through the two-way switching valve 27 and air-selected, and then the paddy contained in the paddy is removed. In order to remove ぷ grains (brown rice), it is supplied to a common paddy brown rice sorting device 33 via a three-way switching valve 45.

Supply hopper 7 of the common paddy brown rice sorting device 33
The paddy thrown into 7 is equalized by an equalizer 78 and a supply gutter 79, and is evenly supplied to each sorter 70. on the other hand,
Since each sorter 70 is given a swinging motion by an eccentric wheel 73, a rod 74 and a swing arm 72, the crushing grains having a relatively large specific gravity swing to the upper slope side by the rough surface of the sorter 70. (See Fig. 4), the branch stalks having a relatively low specific gravity are deflected and drift to the lower side of the slope while floating above the paddy. The degranulation particles are separated by the degranulation partition plate 81 and fall into the cover 80. At this time, since the degranulation outflow gutter opening / closing valve 98 is open, the effluent particles are discharged from the degranulation outflow gutter 84 into the erosion particle receiving gutter 88. This crushed grain is unnecessary when selling it to the government as paddy, and since it has passed through the dryer 28 many times and has been injured such as a crack in its body, it is discarded. The branch scabs on the lower side of the slope are separated by the rice partitioning plate 83 and fall into the rice outflow gutter 87. At this time, since the switching valve 97 is tilted rightward in FIG. The stalk is guided by the switching valve 97 and discharged into the branch stalk receiving trough 94. The branch stalks in the branch stalk gutter 94 are supplied to a deblurring machine (bubble) 99 to remove the branch stalks, and are then air-selected to be reduced as products to the storage silo 19 or the like.

On the other hand, a larger amount of paddy than the crushed grain flows out between the crushed grain partition plate 81 and the crushed grain partition plate 83, and falls in the brown rice outflow gutter 85 and the mixed grain outflow gutter 86. At this time, since the switching valves 95 and 96 in both the outflow gutters 85 and 86 are both tilted to the right in the drawing, the paddy is guided by the switching valves 95 and 96 and discharged into the paddy gutters 90 and 92. You. Paddy gutter 9
The paddy in 0,92 is merged, and the weighing machine 6
After being weighed and measured, the rice is stored in the storage silo 19 as rice sold by the government.

When the paddy thus stored in the storage silo 19 is then shipped through the preparation process, the rice sold by the government in the storage silo 19 is roughly selected through the two-way switching valve 27. After supplying to the mill 3 and selecting the wind, the three-way switching valve 45 is switched and supplied to the hulling machine 34. The polished rice (mixed grains) from which 80-90% has been crushed by the crushing roll of the huller 34 is fed into the supply tank 77 of the common hulled brown rice sorter 33. Then, the rice is equally supplied to the respective sorting boards 70 by the equalizer 78 and the supply gutter 79, and only the brown rice is extracted except the paddy in the polished rice. That is, among the polished rice supplied on the oscillating sorter 70, brown rice having a relatively large specific gravity is swung upward by the rough surface, and paddy having a relatively small specific gravity glides over the brown rice to be inclined. It drifts to the lower side, and mixed grains of brown rice and paddy form a layer in the middle. At this time, the degranulation outflow gutter opening / closing valve 9
8 closes the crushed grain outflow gutter 84, and the switching valves 95 to 97 of the brown rice outflow gutter 85, the mixed grain outflow gutter 86 and the paddy outflow gutter 87 are tilted to the left in the figure, whereby the brown rice partition plate 82 The brown rice flowing out between the crushed grain partition plate 81 and the crushed grain partition plate 81 flows out and is guided by the crushed grain outflow gutter opening / closing valve 98 to flow into the brown rice outflow gutter 85. With the brown rice, it is guided to the switching valve 95 and discharged into the brown rice trough 89. The paddy on the lower side of the slope is separated by the paddle partitioning plate 83, flows out into the paddy outflow gutter 87, is guided by the switching valve 97, and is discharged into the paddy receiving gutter 93, and is fed to the graining machines 44, 4, and the roughing machine. 3
Then, through the three-way switching valve 5, the hulling machine 34 is again disengaged. Further, the mixed particles flowing out between the brown rice partition plate 82 and the paddy partition plate 83 are guided by the switching valve 96 and discharged into the mixed particle receiving gutter 91, and supplied to the supply tank 77 by the graining machine 41.
And is sorted again by the sorting board 70.

The brown rice in the brown rice trough 89 is supplied to the grain sorter 35 via the graining machine 43, and is subjected to grain thickness sorting. Then, the fryer 8, two-way switching valves 9, 24 and three-way switching valve 4
6, the container is weighed by a weighing machine 37 and packed in a flexible container bag 38, or weighed by a weighing machine 39 and sewn in a bag mouth by a sewing machine 40 before being shipped.
