Further, the sample is introduced into the sample introduction pipe 20, but in this case, the elevator frame 33 is interlocked to descend, and the paddy sample to be lifted is the direct pipe 35 in the first cyclone 23.
To reach the second cyclone 36. Therefore this second
While swirling down the inner surface of the cyclone hopper from the cyclone 36, it enters the standby box 52 of the quality inspection apparatus B and stands by.

Further, the airflow mainly reaches the communication pipe 37 together with small 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 18 was first supplied to the removing unit 2, and the remaining paddy samples were then supplied from the collecting hopper 19 to the standby box 52. You can go.

In the removing unit 2, a pair of removing rolls 24, 24
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 15 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 accumulated in a state of being blocked by the discharge gate 12 of the weighing hopper 15 while being supplied to the weighing hopper 40.
0 and the total of the particle size adjustment in the gate portion are measured.
These weighing data are input to the control unit 64, and the sizing yield is calculated from the sizing weight relative to the paddy sample weight.

Then, when the discharge gate 12 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 blocked by the discharge gate 12 closed immediately before by the opening operation of the discharge shutter 42 and weighed. The weighing data is input to the control unit 64, and the tare weight stored in advance is subtracted to calculate the true sizing weight w. 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 / closing of the shutter mechanisms 58 and 59, the shutter mechanisms 58 and 59 flow independently into the lower sample pack device C and are individually packaged. In the sample pack apparatus C, the sizing process of sizing is the last step, and here, the sizing yield of the previous sizing weight W _s / paddy weight W _m , the sizing weight W _s
A slip in which the ratio of the waste particle weight W _k , the volume weight, and the character quality is printed out together with individual data is enclosed.

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 visual judgment. In the above embodiment, the vertical partition member 11 capable of forming the left and right storage spaces is provided inside each of the supply hoppers 6a and 6b.
As described above, the partition member 70 is divided into upper and lower parts, and when the open / close shutters 7a and 7b are closed, first, the sample that is accumulated on the partition member 70 and exceeds a predetermined amount is accumulated on the second partition member 71 that is separately arranged. In this example, the second partition member 71 is provided, and a sample exceeding the second partition member 71 is recovered from the excess sample recovery port 72 to the recovery box 73 outside the machine. With this configuration, by narrowing the area of the hopper upper surface supply port and supplying the sample onto the partition member 70, there is an advantage that an appropriate amount can be overflowed to the next stage and a proper amount can be secured.

[0027]

In the sample supply section, partition members 11, 70 are provided in the plurality of hoppers 6a, 6b to form a plurality of storage spaces inside the hoppers, so that a special distribution mechanism is not required and the construction is easy. Therefore, it is easy to confirm the sample flow down.
