The operation of the above example will be described. A predetermined paddy sample is supplied to the charging hopper 5 of the sizing yield verification apparatus A,
Individual information is input through the operation unit 60. Next, the paddy sample is sequentially supplied to the supply hopper 6a or 6b. Here, for example, the sample in the hopper 6a is divided into two samples by the distribution mechanism 7, and one of them is supplied to the inclined guide chute 8. The paddy sample flowing down the guide chute 8 enters the weighing hopper 9 and is weighed by the weighing device 11.

The other paddy samples supplied to the side of the supply hopper 6b are held in the hopper 6b for a while. Upon receiving the weighing completion signal, the discharge gate 10 is opened and all the paddy samples reach the collecting hopper 12. Here, it is supplied into the sample introducing pipe 20 which is desired downward without waiting. The blower 21 of the sample transport mechanism 5 including the sample introduction pipe 20 is in a driving state, and the paddy sample introduced into the sample introduction pipe 20 reaches the first cyclone 23 through the lifting pipe 22. In the first cyclone 23 part, the elevator frame 33 is located on the lower side by the operation of the air cylinder mechanism 32, and the paddy sample carried together with the air flow reaches the cyclone hopper part 34 from the lifting pipe 22 to cause a swirling flow to generate a weight. The heavy paddy sample falls downward while turning around the inner circumference of the hopper section 34,
It is stored in the supply chute 38. Then, in response to the descending operation of the elevator frame 33, the lower part of the supply chute 38 matches the opening of the machine frame portion 31, is discharged to the outside of the machine frame portion 31, and reaches the removing section 2. On the other hand, the surplus paddy sample that passes through the second guide chute 13 and the collecting hopper 14 is introduced into the sample introduction pipe 20 while looking after the above-mentioned paddy sample reaches the removing section 2. In this case, the elevator frame 33 is interlocked to descend, and the paddy sample to be lifted reaches the second cyclone 36 via the bypass communication pipe 35 in the first cyclone 23 part. Therefore, while swirling down from the second cyclone 36 to the inner surface of the cyclone hopper, it enters the standby box 52 of the quality verification device B and stands by.

Further, the air flow mainly reaches the communication pipe 37 together with a small amount of dust, and returns to the blower 21 via the second cyclone 36 and the discharge pipe 59. The sample can be successively conveyed to the first or second cyclone by such air flow circulation. Since the airflows passing through the first and second cyclones contain dust, it is preferable to appropriately configure a collecting mechanism. Further, in the above description, the paddy sample from the collecting hopper 12 was first supplied to the removing unit 2, and the remaining paddy sample was then supplied from the collecting hopper 14 to the standby box 52. You can go.

In the removing unit 2, a pair of removing rolls 24, 24 are provided.
The unpolished rice is once or twice removed, and the brown rice is supplied to one of the vacant grain selection units 3 through the switching chute 25. By the rotation of the grain selection unit 3, it is separated into waste particles and sized particles. First, the waste particles reach the weighing hopper 9 and are weighed, and then stored in the standby box 52 via the sample introduction pipe 20, the lifting pipe 22 and the like. To be done. Next, the sized particles are supplied to the quantitative hopper 40 and accumulated in a state of being blocked by the discharge gate 10 of the measuring hopper 9,
And the total of the sized particles deposited on the gate will be measured. These weighing data are input to the control unit 62, and the sizing rate is calculated from the sizing weight relative to the paddy sample weight.

Then, when the discharge gate 10 is opened, the gate-part accumulated particle size is discharged, and the surplus particle size removed by the discharging member 41 is also discharged. The sized particles remaining in the quantitative hopper 40 are dammed by the opening operation of the discharge shutter 42 and blocked by the discharge gate 10 closed immediately before, and are weighed. The weighing data is input to the control unit 62, the preset tare weight is subtracted to calculate the true sizing weight w, and at the same time, the volume weight w / the known volume v of the quantitative hopper 40 and the weighing result w are calculated. v is required.

The overflowed sized particles and the sized particles in the fixed quantity hopper 40 are merged and are conveyed up through the sample introduction pipe 20 and the lifting pipe 22. At this time,
The elevator frame 33 of the cyclone 23 is in the lowered position, and all the sized samples are transported to the second cyclone 36 and supplied to the quality measuring instrument 51. When the trait / quality is measured by this quality measuring device 51, the ratio of colored particles mixed in the sizing,
The shattering grain ratio is calculated.

The sized particles that have passed through the quality measuring device 51 are successively collected in the lower collecting hopper 56. During this quality measuring period, the paddy / waste grain samples waiting in the waiting boxes 52, 52 are used for forming each box. By controlling the opening and closing of the discharge gate, the sample flows independently into the sample seal device C below and is individually packaged. In the sample sealing device C, the sizing process of the sizing is the last, and the sizing weight of the previous sizing weight W _s / paddy weight W _m , the sizing weight W _s and the waste particle weight W _k
Enclosed is a slip printed out together with individual data such as the ratio, volume weight, and character quality.

From the above data, it is possible to easily judge which grade the brown rice belongs to by looking at the volume weight and the character quality, and it is possible to eliminate the error caused by the visual judgment.
