In addition, the control unit 54 activates a printer (not shown) provided in the sample sealing device D, prints the sizing yield, bulk weight, and quality for each consignee, and encloses it in the sizing container. are doing.

The operation of the above example will be described. A predetermined paddy sample is supplied to the input hopper 5 of the sizing yield tester A,
Individual information is input through the operation unit 52. The device is running or optionally activated, and the paddy sample is supplied to the sample storage bucket 2. Usually, a plurality of sample paddies will be supplied sequentially. When the storage bucket 2 is raised to a predetermined position, the opening / closing plate 6 is opened 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 and closing shutter 9 is opened in anticipation of a stable state, and the remaining paddy is tilted guide chute 1
Through zero, it reaches the weighing hopper 11. Here, the total weight is measured.

A switching cylinder 20 connected to the fry slotter 15
Switches from the second posture C to the first posture B, and the overflow paddy enters the waiting box 45 via the switching cylinder 20 in the second posture C and stands by. After that, the switching cylinder 20 assumes the second posture C, and supplies the weighed sample paddy to the drying unit 21. In the removal unit 21, a pair of removal rolls 2
The brown rice is de-spinned once or twice by 2, 22, and the brown rice is supplied to one of the empty rotary sorting cylinders 24 via the switching chute 23. By the rotation of the rotary sorting cylinder 24, the dust particles are separated into sized particles and the sized particles. First, the trash particles reach the weighing hopper 11 and are weighed and stored in the standby box 45 via the switching cylinder 20 in the second position. Next, the sized particles are accumulated in the discharge gate 12 of the weighing hopper 11 while being supplied to the quantifying hopper 30, and the total of the quantified hopper 30 and the gate sized particles is weighed. The weighing data is input to the control unit 54, and the sizing yield is calculated from the sizing weight with respect to the paddy sample weight.

Then, when the discharge gate 12 is opened, the gate sized particles are discharged, and the excess sized particles removed by the discharging member 31 are also discharged. The sized particles remaining in the fixed amount 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 pre-set and stored tare weight is subtracted to calculate the true sizing weight w. At the same time, the volume weight w / is calculated from the known volume v of the quantitative hopper 30 and the weighing result w. v is required.

The sized granules overflowing and the sized granules in the quantifying hopper 30 are merged and conveyed upward by the fry slotter 15. At this time, the switching valve 46 of the guide cylinder 42 is in the closed state of the passage, and the sized granules are formed. Is supplied to the quality measuring device 44. When the character and quality are measured by the quality measuring device 44, the ratio of the colored particles and the ratio of the cracked particles mixed in the sizing are calculated.

The sized particles passing through the quality measuring device 44 are sequentially collected in a lower collecting hopper 46. During the quality measuring period, the paddy / dust particles samples waiting in the waiting boxes 45, 45 are supplied to the discharge slotter 49. Then, the process reaches the final stage, the sample sealing device C, and is individually bagged.
In the sample sealer C, the sizing process is the last step, and the sizing / yielding ratio of the sizing / paddy weight, the ratio of the sizing weight to the swarf weight, the volume weight, the trait quality , Are printed out together with the individual data.

In the above data, judging which grade the brown rice belongs to can be easily determined by looking at the bulk weight and the trait quality, and errors due to visual judgment can be eliminated. Thus, regardless of the oversupply of brown rice, the quantitative hopper 3
When the sized particles accumulate at zero, the operation of the dispensing member 31 is performed and the measuring device 13 weighs. Since the volume of the fixed amount hopper 30 is known in advance, the volume weight can be calculated.

In FIG. 5, sample storage buckets 2 and
Are formed of a gas-permeable material, a heater 55 is provided in a lower portion of the circulation transfer process, and a pressure fan 56 and a suction fan 57 are provided before and after the heater 55 so as to sandwich the heater 55.
Hot air can be made to act on the bucket 2 that is shifting to the lowermost position while introducing outside air. In this way, a sample having a high water content can be supplied to various kinds of assay devices, which is advantageous for evaluation at the time of receiving goods at a large-scale grain drying and preparation facility.
