The details are omitted, but the inspection / characteristics, such as colored grains, immature grains, dead rice, and barrel cracks, are received by inputting each measurement light of transmitted or reflected after receiving one grain of brown rice. It is configured so that it can be inspected for each grain. In addition, once all the sized particles are received by the quality measuring device 44, they are sequentially fed to the measurement position one by one by the normal rotation of the one-particle transportation mechanism (not shown), and the sized particles are inspected in a non-destructive state and then moved out of the route. It falls down very much, but
The rest of the sized particles has a structure in which the particles are dropped all at once by reversing the one-grain conveying mechanism and can be collected together with the inspection particles in a collecting hopper 47 for discharging, which is a downward shutter and a discharging thrower 49. Sample sealing device C
It is configured to be supplied to.

The paddy and waste grain samples waiting in the waiting boxes 45, 45 ...
It is configured such that the shutter mechanism provided in each of 5 ... Can be supplied to the discharge thrower 49 and supplied to the sample sealing device C by opening and closing at a predetermined timing. Fifty
Is a motor for driving the discharge thrower 49. The sample sealing device C has a structure in which a padded film, a waste particle, and a sized sample are sorted in the order of packing while sealing a film that is continuously fed in a bag shape, and the same sample can be continuously stored. . Reference numeral 51 is a belt conveyor that conveys the sample storage bag bodies that are continuously fed out to a predetermined position.

The control device D includes an operating section 52 and a CR.
It is composed of a T screen 53 and a built-in control section 54, of which the operation section 52 can input individual information such as a consignee code, date, product type and the like. The control unit 54 outputs timing control signals for driving the driving motors, shutters, measurement units, etc. of the respective units of the above-described sizing yield test apparatus A, quality test apparatus B, sample sealing apparatus D, while measuring signals are output. While inputting a quality measurement data signal and the like, the sized yield for paddy weight and the volume weight are calculated and stored in a storage unit,
A comparison is made with each grade of the agricultural product standard stored in advance in the storage unit to determine which grade the sample brown rice corresponds to. The CRT screen 53 is configured to display a confirmation screen of operation input information from the operation unit 52 and other necessary information. In addition, the control unit 54 activates a printer (not shown) provided in the sample sealing device D, prints the sizing yield, the volume weight, and the quality for each consignee, and encloses it in the sizing container. is doing.

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 52. The device is in operation, or optionally activated, and the paddy sample is fed to the sample storage bucket 2. Usually, a plurality of sample paddy will be sequentially supplied. When the storage bucket 2 moves up to a predetermined position, the opening / closing plate 6 opens and the sample inside is discharged to the supply hopper 8. First, a part of the paddy overflows from the overflow port to the second guide chute 14 side. The opening / closing shutter 9 is opened in consideration of the stable state, and the remaining paddy is inclined guide chute 1
Through 0, it reaches the weighing hopper 11. The total weight is measured here.

A switching cylinder 20 connected to the deep-fried food thrower 15.
Is for switching from the second posture C to the first posture B, and the overflow paddy enters the waiting box 45 via the switching cylinder 20 of the second posture C and stands by. After that, the switching cylinder 20 becomes the second posture C, and the weighed sample rice is supplied to the removing unit 21. In the removing unit 21, a pair of removing rolls 2
The brown rice is removed once or twice by 2, 22, and the brown rice is supplied to one of the vacant rotary sorting cylinders 24 through the switching chute 23. By the rotation of the rotary sorting cylinder 24, it is separated into scrap particles and sized particles. First, the scrap particles reach the weighing hopper 11 and are weighed, and are stored in the standby box 45 via the switching cylinder 20 in the second posture. Next, the sized particles are accumulated in the state of being blocked by the discharge gate 12 of the weighing hopper 11 while being supplied to the quantified hopper 30, and the total of the sized hopper 30 and the gate portion deposited sized particles is weighed. These weighing data are input to the control unit 54, and the sizing yield is calculated from the sizing weight with respect to the weight of the paddy sample.

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 31 is also discharged. The sized particles remaining in the quantitative hopper 30 are blocked by the discharge gate 12 closed immediately before by the opening operation of the discharge shutter 32 and weighed. The weighing data is input to the control unit 54, 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 30 and the weighing result w are calculated. v is required.

The above-mentioned overflowed sizing and the sizing in the fixed amount hopper 30 are merged and ascended and conveyed by the fried grain thrower 15. At this time, the switching valve 46 of the guide cylinder 42 is in the passage closed state and the sizing is performed. Is supplied to the quality measuring device 44. When the trait / quality is measured by the quality measuring device 44, the ratio of colored particles mixed in the sizing and the ratio of crumbling particles are calculated.

The sized particles that have passed through the quality measuring device 44 are successively collected in the lower collecting hopper 46. During this quality measuring period, the paddy and waste particle samples waiting in the waiting boxes 45, 45 are supplied to the discharge thrower 49. Then, the sample sealing device C, which is the final stage, is reached and individually packaged.
In the sample sealer C, the sizing process of the sizing is the last step, and here, the sizing yield of the sizing weight / paddy weight, the ratio of the sizing weight to the scrap grain weight, the volume weight, and the character grade A slip printed out together with individual data is enclosed.

From the above data, it is possible to easily determine which grade the brown rice belongs to by looking at the volume weight and the quality of the traits, and it is possible to eliminate the error caused by the visual determination. In this way, the quantitative hopper 3 can be used regardless of the excessive supply of brown rice.
When the sized particles are accumulated at 0, the dispensing member 31 operates and the weighing device 13 weighs. Since the volume of the quantitative hopper 30 is known in advance, the volume weight can be calculated.

In FIG. 5, the sample storage bucket 2,
2 ... are formed of a breathable material, a heater 55 is installed in the lower part of the circulation transfer process, and a compressed air fan 56 and a suction fan 57 are provided in front of and behind the heater 55,
It is possible to apply hot air to the bucket 2 that is moving to the lowest position while introducing outside air. In this way, samples with high water content can be supplied to various verification devices, which is advantageous for evaluation at the time of receiving goods in large-scale grain drying and preparation facilities.
