DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a grain drying preparation facility for receiving grains from producers, preparing hulling after drying, and shipping.

[0002]

2. Description of the Related Art Conventionally, in a grain drying preparation facility, a received grain is dried by a grain dryer and then adjusted with a hulling or the like before being shipped, and operation buttons or the like arranged on a central control panel of a central control room. A computer that controls each unit based on the above operation is known. In this facility, a part of the received grain such as paddy and wheat is collected as a sample grain, and the grain is transported to a voluntary testing device to inspect the grade of the grain. Inspection by this voluntary testing device is performed by separating grains into sized and immature grains by a grain sorter of the device, and calculating the ratio of the sized to the grain and the like. Then, the price of the dried grain is determined in consideration of the type of the grain, the ratio of the sized grains, and the like.

[0003]

However, the quality and value of a grain cannot be specified only based on the variety or the shape of the grain, and it is important whether the taste matches the taste of consumers. Therefore, in order to judge the value of a grain, it is desirable to examine the taste of the grain and make a judgment in consideration of the taste.

A so-called taste meter, which has been remarkably developed in recent years as a device for performing the taste test, measures the content of a predetermined component contained in a grain and evaluates the taste of the grain based on the measured value. If this taste meter is installed in a conventional grain drying preparation facility, it is considered that the value of the grain can be more accurately evaluated.

[0005] However, this cannot be realized only by adding a taste meter, and various devices related to utilizing the taste meter must also be added. In addition, it is desired that troubles that may be caused by the addition be prevented beforehand, and that the additional devices such as a taste meter operate smoothly. In addition, it is desired that the taste value obtained by the taste meter can be easily grasped and utilized.

In view of the above, the present invention enables various devices such as a taste meter to operate smoothly without trouble, and makes it possible to easily grasp and utilize the taste value of the taste meter. The purpose is to:

[0007]

In order to achieve the above object, the present invention provides a grain drying preparation facility having a central control panel, in which a received grain is dried by a drying device to prepare hulling and the like. Discharging means for discharging part of the grains being dried in the grain dryer as sample grains to the outside of the machine,
A taste meter for inspecting the taste of the discharged sample grains,
A discharge condition detecting means for detecting that a predetermined drying condition for discharging the grain being dried by the grain drying machine from the inside of the machine, and when the discharging condition detecting means detects that a predetermined discharging condition is satisfied. A state detecting means for detecting whether or not the taste meter is in a operable state; and when the state detecting means detects that the taste meter is in an operable state, the discharging means and the taste meter are set to a predetermined state. And control means for giving an instruction to operate according to the procedure.

[0008]

According to the present invention having the above-described structure, the discharge condition detecting means determines whether or not the grain being dried by the grain dryer has a predetermined discharge condition.
For example, it is detected whether or not the moisture value has reached a predetermined value. Then, when the discharge condition is satisfied, the state detecting means detects whether or not the taste meter is in a state where the processing operation can be performed.

Next, when the state detecting means detects that it is in an operable state, the control means instructs the discharging means and the taste meter to operate in a predetermined procedure. As a result, the discharging means discharges a part of the grains being dried by the grain dryer as sample grains to the outside of the machine. Subsequently, the taste meter checks the taste of the milled sample grains.

Next, an example of the grain processing of the embodiment configured as described above will be described with reference to the flowchart of FIG.

First, the grains received by the receiving device 1 are conveyed to the distributor 3 by the grain raising machine 2, and the distributor 3 distributes the grains to the grain dryers 4, 5, 6, and 7, and the distributed grains are each grain. The dryers 4, 5, 6, 7 are stuck. Next, discharge conditions for sampling a part of the grain being dried in the grain dryers 4, 5, 6, and 7 and discharging the sample to the outside, that is, the switching valve 22
Is set and the conditions for discharging the grain to the sample huller mill 23 are set by operating the operation unit 48 (S
1). The discharge condition is a predetermined elapsed time, such as a predetermined moisture value of the cereal (for example, 16%) or 15 hours from the start of drying.

Then, the grain dryers 4, 5, 6, and 7 start drying (S2). Thereafter, when the above-mentioned set conditions are reached (S3), the computer 39 for the sample hulling rice milling machine is used under these conditions. And a state signal is input from sensors 40 and 43 connected to the taste meter computer 42 (S4), thereby determining whether the sample hulling rice mill 23 and the taste meter 24 are all capable of processing. (S5). As a result, if the processing operation can be performed, the switching valve 22 is switched to the opposite side to that in FIG. 2 (S6), so that the grain being dried passes through the corresponding chutes 18, 19, 20, and 21 to the sample hulling. It is supplied to the rice mill 23.

In the sample hulling rice mill 23, the supplied sample is crushed and milled (S7), and when it is completed, the sample is supplied to the taste meter 24. The taste meter 24 inspects the taste of the milled sample (S
8) Find the taste value. The taste value thus obtained is displayed on the display unit 49 provided on the central control panel (S9). Thereby, the worker can immediately grasp the taste value and can utilize it.

On the other hand, when the grains in the grain dryers 4, 5, 6, and 7 reach the finished water content, the drying is stopped. After the grain is temporarily stored in the temporary storage tank 13, the hulling machine 14 and the rice sorting machine 15 are used.
The rice is then hulled, carefully selected, and polished through a rice mill 16.
Here, the customer determines the purchase price in consideration of the result of the above-mentioned taste inspection, weighs it in the weighing machine 17, and then ships it.

According to the above-described grain treatment, the result of the taste test can be obtained at the stage when the original preparation of the grain for drying is completed. Therefore, it is possible to smoothly conduct cereal transactions in consideration of taste inspection without delay or stagnation. Since a suitable purchase price can be determined, it is possible to speed up immediate transactions and stabilize the purchase price.

In the above embodiment, the taste value inspected by the taste meter 24 is compared with a predetermined reference value. If the comparison result is lower than the reference value, the taste test by the taste meter 24 is performed again. On the other hand, it is preferable that the hot air temperature of each of the grain dryers 4, 5, 6, and 7 is lowered by a predetermined value from the current value. If the taste value is lower than the reference value, it is considered that the hot air temperature is too high and there is a possibility that the protein of the grain may be altered during drying, and this can be prevented to ensure proper grain drying and proper taste inspection. Because you can.

In the above-described embodiment, as shown in FIG. 1, the devices are merely arranged according to the order of the processing steps. However, the taste meter 24 is located in the vicinity of the central control panel where the operator is located. , The operator can easily check the taste result displayed on the display of the taste meter 24, and the configuration for displaying the taste value on the display unit 49 provided on the central control panel as described above is omitted. it can. Further, since the rice mill 16 generates a large amount of noise during use and generates a large amount of heat, it is preferable to install the rice polishing machine 16 at a position away from the worker.
