Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving section for receiving a grain in a receiving section and performing a receiving process for weighing the received grain, a drying section for performing a drying process for the grain subjected to the receiving process, and a drying section. The present invention relates to a grain processing method in a grain processing facility including a storage unit for storing the stored grains and a shipping unit for shipping the stored grains after the hull adjustment process.

[0002]

2. Description of the Related Art In the grain processing method in the grain processing facility described above, conventionally, as shown in, for example, Japanese Patent Laid-Open No. 7-68188, when the received grain is weighed in the receiving process, the grain There is a method in which a part of the sample is sampled, the taste of the sample is measured, and the grains are sorted based on the measurement result, and the subsequent drying process and storage process are performed.

[0003]

SUMMARY OF THE INVENTION The above-mentioned prior art is based on the measurement result of the taste, and for the grain having a high taste evaluation value, for example, low-temperature drying is performed so as not to impair the quality, and the taste evaluation Grains are processed under conditions different from those of low grain.

However, according to the above-mentioned conventional technique, after the taste is measured in the receiving process and the products are sorted based on the measured information, the sorting state is kept as it is until the final shipment from the shipping department. Since the processing is performed in, there are the following disadvantages and there is still room for improvement.

For example, the grain may be stored in the storage unit for a long period of time after the completion of the drying process, and if the storage period is long, the taste of the grain deteriorates during the storage. Even if the taste evaluations are almost the same at the time of receiving the cargo, the tastes after storage may be different if the storage periods are different.
Further, even when the drying process is performed, it is possible that the taste varies depending on the drying conditions. However, since the measurement of the taste is only performed in the receiving process, the grains having different tastes may be shipped as having the same quality information, and there is room for improvement in this respect.

The present invention has been made in view of such a point, and an object thereof is to ship based on more appropriate taste measurement information in consideration of a change in taste associated with grain processing. The point is to provide a grain processing method in a grain processing facility that enables the above.

[0007]

According to the grain processing method of claim 1, before the drying treatment , the taste of the grain is improved.
, Sort based on the measurement results,
Perform the subsequent drying process under different conditions depending on the taste, measure the taste of the grain before the shipment from the shipping department after the drying process is finished, sort based on the measurement result, and then The grain treatment was performed under different conditions depending on the taste .

That is, before the drying process is performed, specifically, before the weighing in the receiving unit, after the weighing is performed, or before the weighing is performed, the taste of the grain is measured. Then, the subsequent grain processing is executed under different conditions depending on the taste. Furthermore, after that, before the product is shipped from the shipping section after the drying process is completed, specifically, before being stored in the storage unit after the completion of the drying process or after a set time has elapsed since the storage was started. Alternatively, when the hulling adjustment process is performed, the taste of the grain is measured, and the subsequent grain process is executed under different conditions depending on the taste.

Therefore, in comparison with the conventional technique in which the taste is measured and sorted only in the receiving step and the subsequent processing is executed, the taste is measured during the grain processing and the subsequent processing is changed. Therefore, even if the eating quality changes due to the execution of the grain processing, it is possible to detect the change and execute the grain processing in a more appropriate state. It became possible to ship based on more appropriate taste measurement information in consideration of changes in taste.

According to the grain processing method of claim 2,
The taste of the grain and the water content of the grain were measured based on the spectroscopic analysis of the transmitted light or the reflected light of the light with which the grain was irradiated.

When the taste and moisture are separately measured by measuring not only the taste of the grain but also the water content based on the spectral analysis of the transmitted light or the reflected light of the light irradiated on the grain. In comparison, the measurement can be performed efficiently, and the configuration is simplified without the need to separately provide a dedicated measuring instrument.

According to the grain processing method of claim 3,
Before the grain processing for drying is performed, before the acceptance in the receiving section or before the weighing is performed after the acceptance, the taste of the grain is measured, so that the grain can be unloaded. The taste is measured while weighing and other processes in the process are performed, and it is possible to improve the time efficiency for the processes such as the receiving process and the drying process on the grain. Becomes

According to the grain processing method of claim 4,
Before the storage in the storage unit after the drying process is finished, the taste of the grain was measured, so by comparing with the taste measured before the drying process, the taste was changed by the drying process. It is possible to determine whether or not.

According to the grain processing method of claim 5,
After the drying process is completed and after the set time has elapsed since the storage was started, the taste of the grain was measured, so that, for example, compared with the taste measured in the previous step such as before the drying process. By doing so, it is possible to detect a change in taste due to storage.

According to the grain processing method of claim 6,
After the completion of the drying process, when the hulling adjustment process is performed, the taste of the grain is measured, so that the taste immediately before the final shipment can be determined, and thus the taste measurement result. Can be sorted and shipped according to.

According to the grain processing method of claim 7,
After the storage in the storage unit is completed, the grains sorted based on the taste measurement result are mixed at a set ratio, and the hull adjustment process is performed to ship the mixed grains.

In other words, before the hulling adjustment process is performed, the grains sorted based on the taste measurement result are mixed at the set ratio and shipped, so that the grain process such as the drying process and the storage process is performed. It became possible to mix grains based on more appropriate taste measurement information and to ship grains of desired quality in consideration of changes in taste associated with being eaten.

To explain the function of the flow rate adjusting tank 4, since the load receiving weighing machine 6 is configured as a so-called batch type weighing machine, the load receiving weighing machine 6 temporarily stores grains therein during weighing. Ready to go. Therefore, the next weighing cannot be performed unless the grain received for weighing is discharged. Therefore, the flow rate adjusting tank 4 is provided with two storage units so that one storage unit stores the grain in the other storage unit while the storage unit performs the weighing operation. Even if the weighing has not been completed, the next load receiving process can be started so that the efficiency of the load receiving process can be improved. However, when the amount of cargo to be received is large, the grain may be stored in a state in which the grain of the same receiving destination is distributed to the two storage units.

The weighed grain discharged from the load receiving weighing machine 6 is lifted up by the second lifting conveyor 7 and stored in one of the storage bins 8 via the relay conveyor 19 and the moving conveyor 20.

The grain discharged from the container is conveyed to the selection machine 11 or the selling weighing machine 12 via the flow rate adjusting tank 10. However, the grain discharged from the selection machine 11 can be conveyed to the weighing machine 12 for sale. The grain weighed by the weighing machine 12 for sale is fed by the sixth feeding conveyor 35, and then the grain adjusting device 13
It is supposed to be transported to. However, a switching valve 36 is provided at the end of the sixth lifting conveyor 35, and the grain lifted by the sixth lifting conveyor 35 can be returned to the silo 9 from the horizontal feeding conveyor 37 above the silo 9. It is like this.

The grain discharged from the hulling adjustment device 13 is
It is lifted upward by the seventh lift conveyor 38 via the stone removing machine 14 and is transferred to the adjusting tank 15 of the shipping weighing machine 16 or another shipping weighing machine 17 via the switching valve 39. It is like this. The grain discharged from the shipping weighing machine 17 is lifted up by the eighth lifting conveyer 40, and is divided into a plurality of shipping tanks 18 by a predetermined amount via the horizontal feed conveyor 41. It is designed to be stored in the closed state. The grain discharged from the shipping tank 18 is discharged from the shipping / transporting conveyor 42 to a loading platform of a truck for transportation and shipped.

In this grain processing facility, the taste of the grain is measured before the drying process is performed and before the drying process is completed and before the product is shipped from the shipping section E, and based on the measurement result. Sorting is performed so that subsequent grain processing is performed under different conditions. That is, a quality determination device F that determines the taste and other quality information of the sample paddy collected from the grain that is the target of the grain treatment is provided, and after the drying process is completed, the shipping section E It is designed to measure the taste of grains before they are shipped from. Specifically, before the drying process is performed, that is, when the supplier inputs grain, after the acceptance process is completed at the reception U, the grain is input to the load receiving hopper 1. First, sample paddy is collected from the grain to be treated with the grain. Also, after the drying process is completed, before shipment from the shipping section E, that is, after the drying process is completed and before being stored in the storage section C, and after the storage is started, a set time has elapsed. After that, further, at each timing when the hulling adjustment process is being performed, sample hulls are collected from the grain that is the target of the grain process, and the taste etc. is determined for each sample hull. Of.

Next, the structure of the quality judgment device F will be described. As shown in FIGS. 3 and 4, on the front side of the device, an input port 4 into which the sample paddy collected from the grain is input.
8 and a touch panel 49 for manual operation are provided, a load cell 50 for detecting the total weight of the sample paddy fed down from the input port 48, and a huller 5 for hulling the sample paddy.
1. Load cell 52 for measuring the weight of brown rice after hulling, character quality of sample paddy, for example, immature grain, damaged grain, dead rice,
Appearance quality meter 5 for measuring appearance quality such as coloring and body cracking
3, a taste meter 54 for determining the taste of sample paddy, a grain sorter 55 for sorting the sized granules, a load cell 56 for measuring the weight of the sized granules, and a transport unit 5 for lifting and transporting the paddy between them.
7 and the like. As shown in FIG. 4, the input port 48 is provided with a rotary valve 58 whose operation time can be changed and adjusted to supply a set amount of sample paddy among the input paddy, and to set the set amount of paddy rice a plurality of times. It can be supplied one by one. The paddy left over from the input port 48 can be discharged to the outside from the discharge part 60 via the outlet side path and collected by switching the flow path switching valve 59.

The taste meter 54 measures the taste based on a well-known measurement technique such as spectroscopic analysis. The taste meter 54 irradiates the sample paddy with light and transmits the irradiated light to the paddy. Or based on spectroscopic analysis of reflected light,
It is configured to measure the proportion of components (for example, amylose, starch, etc.) corresponding to the taste contained in the grain and obtain the taste evaluation value based on the measurement results.
In addition, the taste meter 54 can simultaneously measure the water content contained in the paddy.

Then, as shown in FIG. 5, after measuring the total weight of the sample paddy and hulling it, the weight of the brown rice is measured, and the sample paddy is divided into an appearance quality meter 53 and a taste meter 54. Then, they perform predetermined measurement in parallel. Those measurement results are input to the control device 61, which will be described later. Further, the yield is measured from the sizing weight measured after grain selection, the brown rice weight, the total paddy weight, etc., and this information is also input to the control device 61. It should be noted that the processing time from when the sample paddy is introduced and the processing is started until the measurement results of the appearance quality meter 53 and the taste meter 54 are obtained is about 90 seconds, and further until the yield is measured. About 90
It takes a second processing time.

After the grain is loaded into the receiving hopper 1 and the sample paddy is loaded into the loading port 48, the supplier receives his / her identification number (for example, home telephone number) or the target grain at the reception U. The production lot number (field number, etc.), the information such as the type of grain, and the information about which of the two receiving hoppers 1 should be used for input are input. Input to device 61,
Based on this input information, subsequent processing of grain and quality measurement information are managed.

FIG. 6 shows the movement state of grains in the entire grain processing facility and the flow of various measurement information.
Grains brought in from multiple suppliers (farmers) may differ from each other in quality and moisture content such as taste and quality as described above, but such quality and moisture are measured with sample paddy, Based on the measurement results, the grain quality is comprehensively evaluated and sorted, and subsequent processes such as a drying process are processed under mutually different conditions suitable for each measurement state. In the figure, the fact that the grain flow after the drying process is branched into multiple does not mean that multiple dryers process them in parallel at the same time, but the grain flow in such a sorted state is It represents. The control device 61 ships the grains of different qualities managed separately based on the separately input shipping instruction information individually and in a state in which they are mixed at a set mixing ratio. In order to make it possible to switch from the silo 9 to a state in which the discharge state of grains is controlled, the drying process and the measurement information of a temperature sensor (not shown) or a moisture meter provided in the silo 9 are displayed on the monitor. It has become.
Further, the detection information and the like in each of the above steps are stored as a quality information database for each input information such as a plurality of identification numbers and production lot numbers, and various supplier-specific information is provided to each supplier. To be given.

Specifically, the control device 61 is adapted to execute the following operations. That is, the grain transport state on each of the transport conveyors and the lifting conveyors, the switching operation of each switching valve, and the storage bin 8
Opening and closing each shutter 21 provided on the or silo 9,
Each of the blending process based on the shipping instruction information and the sorting operation for storing grains in a storage bin 8 selectively selected from any of the plurality of storage bins 8 in a preset order are performed. Is configured to.

Next, the sorting process for evaluating the quality of grain and sorting will be described. When the supplier inserts the sampled rice collected from the grain into the input port 48 at the reception desk, inputs the input information, and instructs the touch panel 49 to start the measurement, the quality determination device F starts the measurement. .
After that, the grain is put into the receiving hopper 1 to start the transportation of the grain. Incidentally, as shown in FIG. 7, it takes about 60 seconds for the grain input process, and the time required for the grains to be conveyed from the receiving hopper 1 to the rough sorter 5 is about 90 seconds. is there. As described above, the time required for the quality determination device F to finish measuring the taste, character quality, and water is about 90 seconds. Therefore, the quality determination device F performs the determination operation by the weighing machine 6 for receiving cargo. It will end by the time it starts.

The measurement information of the taste, character quality and water measured by the quality judging device F is transmitted to the control device 61 immediately after the measurement is completed. Then, the control device 61, based on the measurement information of the taste, character quality, and water, among the plurality of storage bins 8, the storage bin 8 for storing grains.
Is selected, and the weighing by the load receiving weighing machine 6 is started at this time. When the weighing is completed, the weighing information is transmitted to the control device 61. In addition, the selection of the storage bin 8 by the control device 61 is performed by specifically moving the entire moving conveyor 20 provided above the storage bin 8 in the lateral direction so that the grain discharge position (the lower side end in the transport direction) is set. , By adjusting the position so that it is located above the selected storage bin 8. The moving conveyor 20 can be switched between forward and reverse conveying directions, and the discharge position can be selectively adjusted for any of the storage bins 8 while reducing the lateral movement amount. After that, the grain is discharged from the storage bottle 8 and conveyed to the dryer k to be dried, but at this time, an appropriate condition is determined based on the moisture information measured by the quality determination device F. At the same time as the drying process is performed, the drying process is basically performed based on the input information and stored in one of the silos 9, and the shipping process is appropriately performed. .

By the way, as described above, even after the drying process is completed, before the storage in the storage unit and after a set time (for example, several weeks to several months) has elapsed since the storage was started (that is, , In the middle of the storage process) and in the respective states such as when hulling adjustment processing is being performed,
The quality determination device F measures the taste, character quality, and water information of the collected sample paddy, and the measurement information is transmitted to the control device 61. Then, the control device 61 performs subsequent grain processing under different conditions based on the measurement information of the taste, character quality, and water. For example, if there is a large change in the taste measured before the goods are received, the sorting method after that is changed so that, for example, a grain with a high taste evaluation is not classified as having a low taste evaluation. It is possible to manage them separately, or to manage the taste evaluation of the mixed grains as a quality information database and make it correspond to subsequent sales information.

[Other Embodiments] (1) In the above embodiment, it is assumed that before the drying process is performed, the taste is measured before receiving the cargo, and after the drying process is finished and before the shipment from the shipping section. Before the drying process is finished and stored, after the set time has elapsed since the storage was started, and the taste is measured at each timing during the hulling adjustment process, the method is not limited to such a method. Alternatively, before the drying process is performed, the taste may be measured before the weighing is performed after the cargo is received, or the taste may be measured during the weighing. Further, after the drying process is completed and before the shipment from the shipping section, the measurement may be performed only once any one of the above timings, or the measurement may be performed at two or more timings thereof. Often,
It may be measured at other timing.

(2) In the above embodiment, a dedicated dryer (heat-power drying or the like) is provided, but the present invention is not limited to such a configuration, and the storage bottle is provided with a drying function by ventilation drying. For example, it is dried in a storage bin to a semi-dry state (for example, to a moisture content of about 17%), then temporarily stored in a silo, and then circulated between the silo and the storage bin for low temperature dehumidification. It may be dried.

(3) In the above embodiment, in the load receiving process, the weight is temporarily stored in the storage bin after the weighing by the load receiving weighing machine is finished, but the present invention is not limited to such a configuration, and after the weighing is finished. Alternatively, the process may be performed so that the process directly proceeds to the drying process under the control based on the discrimination information.
