No. 01941). However, among the factors that determine quality, for example, cracks and insect damage change during drying treatment or during storage, while on the taste, fatty acids as one factor determining this increase during storage, and when receiving goods, There are cases where it cannot be predicted exactly.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve the above-mentioned drawbacks and to make the grain quality or taste of prepared and shipped uniform, and has taken the following technical means. That is,
In a joint grain preparation facility in which a plurality of storage bins 5a to 5d for temporarily storing received raw cereals are provided, and a plurality of silos 15a to 15d for receiving and storing cereals dried by the dryer 12 are provided. A silo and the storage bin are connected by a transfer path, and in the middle of the transfer path, a quality measuring device 24 that receives a part of the grain being transferred and measures the quality of the grain, or a taste measuring device 27 that measures the taste. connection,
The reservoir on the basis of the quality measurement results or taste measurement
It is configured to sort and discharge to bins 5a to 5d . In addition, it is configured to sort and discharge the storage bins 5a to 5d based on the quality measurement result or the taste measurement result, and to transfer the grain having substantially the same quality or taste to the preparation process for shipping preparation.

[0004] In addition, the storage bins 5a to 5d are configured to be sorted and discharged based on the quality measurement result or the taste measurement result, and the grain having substantially the same quality or taste is reduced to the same silo. is there.

[0005]

When the rice stored in the silos 15a to 15d is shipped, the quality or taste is measured by using the quality judgment device 24 or the taste measuring device 27, and the storage bins 5a to 5d are determined based on the measurement result. It is sorted discharged. In addition, storage bin 5 for receiving raw rice and storing it primarily
a to 5d can be sorted and distributed for each grade or taste. A necessary one of the distributed grains is prepared for shipment and supplied to the market.

As described above, since the quality or taste is determined after the drying treatment or before storage of the grain during storage, it is possible to reflect the influence on the quality and taste after receiving the grain. In addition, since empty storage bins are used for each grade or taste, separate tanks are not required and the installation equipment can be effectively used. In addition, when rotating for the purpose of preventing the deterioration of the grain in the silo, it is possible to distribute and sort using the storage bin for each grade while measuring the grade or taste during the course of the process. Etc. can be implemented efficiently.

[0007]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the flow of a large-scale dry preparation facility for drying and preparing paddy brought in from each farmer. Grain from a receiving hopper 1 passes through a receiving elevator 2, a receiving measuring device 3, and a bin loading elevator 4. Multiple storage bins 5
a, 5b, 5c, 5d. That is, a supply flight conveyor 6 is provided above the storage bins 5a to 5d, and supply ports and shutters 7a to 7d corresponding to the number of bins are provided at predetermined locations. The storage bins have opening / closing shutters 8a to 8d at their outlets. These shutters 8
The terminal end of the belt conveyor 9 looking downward from a to 8d is connected to the bin discharge elevator 10. The upper part of the elevator 10 is connected via a four-way switching valve 11 to the flight conveyor 6, the grain dryer 12, the silo embankment elevator 13, and the hulling sorter 14 so that the grain can be transferred. Also, a two-way switching valve 28 may be provided at the outlet of the bin loading elevator 4 to set a route from the flight conveyor 6 to the grain dryer 12.

[0008] The silos are the main silos 15a to 15c having a large capacity.
15d and small-capacity gap silos 16a to 16c. Of these, grain supply to the main silo is performed by operating shutters 18a to 18d provided at each discharge port of the flight conveyor 17. On the other hand, the grain supply to the gap silos 16a to 16c is performed in parallel with the conveyor 17 on the flight conveyor 1.
9 is provided by the shutters 20a to 20c.
In addition, a two-way switching valve 2 is provided at a discharge portion of the silo stretching elevator 13.
1 so that grains can be supplied to the flight conveyor 17 or 19.

Opening / closing shutters 22a to 22d are provided on the discharge side of the main silos 15a to 15d so that the main silos can be discharged to a discharge conveyor 23 in the form of a belt conveyor. The end of transfer of the discharge conveyor 23 is connected to the bin loading / lifting machine 4 so that the grains in the main silo can be returned to the storage bin. A quality measuring device 24 is provided at the end of the discharge conveyor 23. Quality measuring device 24
Is a mode in which optical transmitted light or reflected light is detected, the detection signal is taken into the control unit of the computer 25, and the degree of body cracking, coloring, presence or absence of damage, and the like can be calculated. The control unit of the computer 25 sorts, for example, into good grade, standard grade, and poor grade according to the grade calculation result, and stores the grains in the main silo into the storage bins 5a, 5b, 5b, 5b according to these sort signals.
In this configuration, a two-way switching valve 28 switching signal and an opening / closing signal to one of the shutters 7a, 7b, 7c are output so as to be distributed and supplied to 5c.

A sample extracting section 26 is provided in the middle of the bottle inserting and lifting machine 4 and is connected to a taste measuring device 27. The taste measuring device 27 measures the starch, protein, fat, water value, etc. by a near-infrared spectroscopic analyzer (not shown), and these data are sequentially sent to the control unit and can be calculated as the taste value. And The gap silos 16a-1
Shutters 29a to 29c are disposed at the discharge port 6c, and the shutters 29a to 29c are viewed from the discharge conveyor 30 in the form of a belt conveyor. The end portion side of the discharge conveyor 30 communicates with the grain dryer 12 via the intermediate elevator 31.

A discharge conveyor 32 is provided at a lower discharge port of the grain dryer 12, and can be transferred to a silo extension elevator 13 or a bin extension elevator 4 via an elevator 33 and a two-way switching valve 34. Brown rice from the hulling sorter 14 is configured to remove scrap rice while passing through a grain sorter 35 and stored in good brown rice tanks 36a to 36c of a plurality of sections.

The operation of the above example will be described. After the received paddy is weighed by the receiving weighing device 3, the bin filling elevator 4
It is supplied to a predetermined (vacant) storage bin, for example, 5a via the flight conveyor 6. In the storage bin 5a, the so-called ventilation operation can be performed in which the bin is loaded into the original storage bin 5a via the discharge conveyor 9, the discharge elevator 10, and the bin conveyor 4 and the flight conveyor 6, so that the high-moisture paddy is prevented from becoming stuffy. Is possible.

The paddy in the storage bin 5a is temporarily removed from the grain dryer 12
Through the gap silo 16a.
The water is dried and finished to a predetermined moisture value while reciprocating between “a” and the grain dryer 12. The dried paddy is set so that it can be supplied to the flight conveyors 17 to 19 by switching the two-way switching valve 21, and is transferred to and stored in appropriate main silos 15a to 15b. At the time of shipment, when taking out the paddy stored in the main silo, the shutters 22a to 22 of the silo discharge port of the desired variety are taken out.
Operate any one of the steps d to discharge it onto the discharge conveyor 23. The discharge conveyor 23 discharges the paddy to the bin filling elevator 4.

By the way, a quality measuring device 24 is provided at the end side of the discharge conveyor 23, and the quality of the paddy being transported is reduced and selected into brown rice before the quality is measured. The two-way switching valve 28 is set on the supply flight conveyor 6 side. Next, the quality of the sample paddy is measured and compared with a preset quality standard. If the quality is good, for example, the shutter 7a is opened and the grain can be stored in the storage bin 5a. When the quality is the standard quality or the poor quality, the shutter 7b or 7c is similarly opened and can be stored in the storage bin 5b or 5b.

If the quality of the rice hulls sorted by quality by using the storage bins 5a to 5c is to be prepared and shipped, the storage bin 5a-containing paddy is targeted. It is dropped on the belt conveyor 9 in conjunction with the operation. The paddy reaches the paddy sorter 14 via the bin discharge elevator 10 and the four-way switching valve 11. Here, the rice is subjected to degassing, wind selection, and sorting, and then passes through a grain sorter 35 and is collected in good brown rice tanks 36a to 36c while leaving only the brown rice. In this way, brown rice of uniform quality can be prepared for shipment, and can be supplied to the market as a product with a strong desire for luxury and differentiation.

In the above case, the case where the paddy in the main silo is shipped and prepared has been described. However, the same processing is performed in the case of so-called silo rotation, and after sorting into storage tanks for each grade, storage is performed for each grade. They may be stored in tanks or separately returned to the main silo. If the number of silos is insufficient with only the main silo, a gap silo may be used for storage. In this way, the prediction of the commercial value at the time of the subsequent shipment preparation is assured.

As described above, the quality of paddy stored in the main silo is measured, sorted by quality using an empty storage tank, and subsequent shipping preparation and silo rotation are performed for each quality. Therefore, there is no need to prepare separate tanks. In addition, since the taste measuring device 27 is provided in the middle of the bottle filling elevator 4, the paddy lifted from the main silo via the discharge conveyor 23 to the elevator 4 is appropriately subjected to pretreatment such as removal and grinding. The taste value is obtained by the post-component analysis, and the taste value is distributed and supplied to the storage tanks 5a to 5c according to, for example, high, standard, and low of the taste value. In the same manner as in the case where the paddy sorted for each taste value is sorted for each quality, the paddy having a taste that meets the customer's request is prepared for shipment and supplied to the market. In addition, silo rotation is performed for each taste value, and it is easy to adjust and manage the supply timing to the market, especially when the deterioration index is known by analyzing the internal components.

Although the quality measuring device 24 in this embodiment is intended for the paddy on the discharge conveyor 23, when the drying process is required, a portion is sampled and measured as in the taste measuring device 27. May be. When a long time is required for the measurement, the transfer by the discharge conveyer 23 may be intermittently performed and distributed to the storage tank while measuring the timing. The moisture value of the measurement items by the taste measuring device 27, or the paddy having a high moisture value returned by the moisture value separately measured can be collectively stored in any of the storage bins,
It can be additionally dried to a predetermined moisture value while returning to the storage bin while being supplied to the grain dryer 12 via the discharge elevator 10.

In the above embodiment, the quality or taste is measured and distributed in a predetermined manner during the rotation of transferring the raw rice stored in one of the storage bins (provisionally 5a) to another storage bin. Is also possible. In other words, a closed circuit is constructed in which the raw rice in the storage bin 5a is once passed through the dryer 12 in a ventilation dry state via the discharge elevator 10 and is returned to the storage bin from the insertion elevator 4 again.
4 or by incorporating the taste judging device 27, by automatically controlling the open / close shutters 7a to 7d, it is possible to unify the rice to any quality or taste using bin rotation.

The above-mentioned quality or taste value is displayed on a display unit (not shown) of the computer 25. During the bin rotation of the raw rice, the occurrence of so-called burned rice is monitored particularly by measuring the quality. By doing so, it becomes convenient for the subsequent shipping schedule management. That is, when stored in raw paddy, a large amount of burnt rice is generated, which is said to be closely related to an increase in the degree of fatty acid as an index of deterioration in taste. By monitoring the occurrence ratio, the ratio of fatty acid degree, which is a factor of the decrease in taste, can be predicted, and can be used as a standard of the storage days.

Reference numeral 37 denotes a quality measuring device or a taste measuring device for judging the taste of the sample grains from the brown rice discharging portion of the hulling sorting device 14, and a plurality of good quality measuring devices are provided according to the result of the quality or taste measurement. Brown rice tanks 36a, 36b,
36c so that the paper can be discharged.
