EXAMPLES Next, examples of the present invention will be described with reference to FIG.

In FIG. 1, reference numeral 1 is a load receiving hopper for receiving brown rice produced at a farmer or a grain drying and preparing facility. It is configured so as to be stuck in a grain size selector 3 for sorting waste wood. The two outlets of the particle size selector 3 are respectively connected to a sizing machine 4 for measuring the weight of the selected sizing and a scraping rice weighing machine 5 for measuring the weight of the sorted waste rice.

The sizing machine 4 is constructed so as to guide the brown rice after weighing to the elevator 6 for squeezing, and at the time of weighing, a part thereof is extracted (collected) as a sample for measurement.
Then, the brown rice is guided to the deterioration degree detection device 7.
The brown rice deterioration degree detection device 7 is electrically connected to a central control device 8 that controls the entire brown rice storage management facility.

The deterioration degree detection device 7 for brown rice detects the deterioration degree and moisture content of brown rice by using a near infrared analysis method (near infrared absorption spectrum method). The index of the degree of deterioration of brown rice is, for example, the degree of fatty acid, the degree of oxidation, or the germination rate, and the degree of deterioration of brown rice is detected by measuring these in the following manner.

First, the fatty acid content is measured using a known near infrared analyzer. In addition, the degree of oxidation correlates with the content of aldehydes and ketones, as well as the degree of unsaturation of unsaturated fatty acids,
That is, there is a correlation with the iodine value. Therefore, for the degree of oxidation, for example, the iodine value is measured by a near infrared analyzer and the degree of oxidation is estimated from the measured value. Further, the germination rate can be obtained by actually conducting a germination test and determining the proportion of grains that have germinated soundly. This germination rate is related to the fatty acid content and the iodine value. Therefore, the germination rate is indirectly obtained by measuring these with a near infrared analyzer.

The relationship between the degree of fatty acid, the germination rate, or the unsaturated degree of unsaturated fatty acid, which is an index of the degree of deterioration of brown rice thus measured, and the number of harvest days is shown in FIG.
As shown in (C).

The end of the stake elevator 6 is connected to the beginning of the sorting conveyor 9, and a plurality of storage tanks 10A to 10K are arranged below the sorting conveyor 9. The sorting conveyor 9 sorts brown rice into any one of the storage tanks 10A to 10K.

1 is set. One end of the discharge conveyor 11 is connected to the weighing machine 13 and the other end is connected to the blending elevator 15 via the switching valve 12. The weighing machine 13 is connected to a packaging machine 14 for packaging the weighed brown rice.

The end of the blending elevator 15 is looked into the upper spout of the blending tank 16 so that it can be stretched. The blending tank 16 is provided with a blending weighing machine 17 that weighs the weight of the brown rice stuck in the tank 16. Blending tank 16
Just below the outlet of the blending device 18
To place.

The discharge port of the blending device 18 is connected to a blended rice storage elevator 20 via a discharge conveyor 19. The end of the elevator 20 is connected to the start end of the stake conveyor 21, and below the stake conveyor 21 are a plurality of storage tanks 22A for storing the mixed brown rice.
Place 22C. The feeding conveyor 21 has a function of distributing brown rice to any one of the storage tanks 22A to 22C or the weighing machine 25.

Below the discharge ports of the plurality of storage tanks 22A to 22C, a discharge conveyor 23 for conveying the discharged brown rice is provided. The end of the conveyor 23 is connected to the distribution conveyor 29 via the shipping elevator 24. Below the distribution conveyor 29, a weighing machine 25, a brown rice dryer 27, and a brown rice tempering machine 28 are arranged so that the distribution conveyor 29 can distribute to any one of them. The weighing machine 25 is connected to a packaging machine 26 for packaging the weighed brown rice. The brown rice dryer 27 and the brown rice tempering machine 28 are configured so that the brown rice can be circulated during drying or tempering, and are configured to guide the brown rice to the weighing machine 25 after drying or tempering.

Next, an example of the control system of the brown rice storage management facility thus constructed will be described with reference to FIG.

The above-mentioned central control unit 8 is composed of a computer. The central controller 8 is connected with a brown rice deterioration degree detector 7, and is also connected with a sorting conveyor 9, a discharging conveyor 11, a switching valve 12 and the like as control targets.

Next, an example of the operation of the brown rice storage management facility having such a configuration will be described below.

Now, when the consigned brown rice is put into the consignment hopper 1, it is supplied to the grain size selector 3 by the consignment elevator 2 where it is sized and sorted into waste rice. The sorted waste rice is loaded into a waste rice tank (not shown) whose weight is weighed by the scrap rice weighing machine 5.

On the other hand, the selected sized particles are sized by the weighing machine 4
Is weighed by. At the time of weighing, a part of the brown rice is extracted (collected) as a sample, and the sample is guided to the deterioration degree detection device 7 of the brown rice. The brown rice deterioration level detection device 7 detects the deterioration level and moisture content of the brown rice sample by using a near infrared analysis method.

When the degree of deterioration and moisture content of brown rice are detected in this manner, the brown rice currently being received is stored in a predetermined storage tank among the storage tanks 10A to 10K according to the degree of deterioration and moisture content. The elevator 6 for stake-in, the conveyor 9 for sorting, etc. are controlled so as to be staken in.

Therefore, the degree of deterioration of brown rice is defined as the degree of fatty acid, and the storage tanks 10A to 10K to be filled in according to the degree of fatty acid and the water content are determined in advance as shown in FIG. At 10K, brown rice can be added to each group for storage and management for each group having almost the same fatty acid content and water content.

As described above, by grouping the brown rice according to the fatty acid content and the water content, the following storage management and shipping can be performed.

For example, in the storage tank 10I (see FIG. 4) in which brown rice with high fatty acid and high water content is filled, it is considered that the brown rice has deteriorated considerably, so that it is preferentially shipped. In this case, when the brown rice in the storage tank 10I is discharged from the discharge port, it is guided to the weighing machine 13 via the discharging conveyor 11 and the switching valve 12 and weighed. Shipped.

When brown rice with a low moisture content is put in, as in the storage tank 10K, the grain is refined to a predetermined moisture value by the brown rice tempering machine 28 before shipment. In this case, the brown rice discharged from the discharge port of the storage tank 10K is put into the brown rice tempering machine 28 via the discharge conveyor 11, the switching valve 12, the blending elevator 15, and the like. Then, the brown rice that has been conditioned to a predetermined moisture value by the brown rice tempering machine 28 is guided to the weighing machine 25 and weighed, and after weighing, it is packaged by the packaging machine 26 and shipped.

When high-moisture brown rice is stuffed like the storage tank 10J, it is dried to a predetermined moisture value by the brown rice dryer 27 before shipment.

When the fatty acid content is medium and the water content is low, the deterioration of quality can be suppressed by storing it as it is due to the low water content even if the fatty acid content is slightly high.

Further, in the case of brown rice with a medium degree of fatty acid and high moisture content, it is mixed with low moisture brown rice at a predetermined ratio using the blending device 18, and the moisture value is set to a predetermined value before shipment. That is, brown rice in an amount corresponding to a predetermined ratio is separately transferred from the two storage tanks filled with brown rice to be mixed to the blending tank 16, and the blending device 1
After mixing these brown rice in 8 and weighing with the weighing machine 25, it is packaged with the packaging machine 26 and shipped.

As described above, in this embodiment, the deterioration degree and moisture value of brown rice are detected at the time of receiving the goods, and the brown rice is sorted into a predetermined storage tank according to the detection result. In addition to being able to ship sequentially from brown rice,
Considering the degree of deterioration, it is possible to properly mix brown rice and adjust the moisture content of brown rice.

In the operation example of the above embodiment, the degree of fatty acid is measured as the degree of deterioration when the brown rice is received, and the moisture value is also measured, and one of the storage tanks 10A to 10K is measured according to the measurement result. I decided to sort the brown rice. However, in the present invention, the germination rate and the degree of oxidation are measured as the degree of deterioration when receiving brown rice, and the moisture value and the protein content are also measured, and any one of the storage tanks 10A to 10K is measured according to the measurement results. You may sort the brown rice in. In this case, the storage tanks 10A-1
The brown rice stuck to 0K can be stored and shipped in a predetermined manner as described above.

The present invention does not need to be provided separately as in the embodiment, but may be provided together with a conventional rice polishing facility.
