DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying apparatus mainly used in a cereal drying processing facility.

[0002]

2. Description of the Related Art Conventionally, various dry processing facilities have been provided in which grains are collected, dried and stored, and after processing such as hulling, adjusted and shipped.

This drying treatment facility is disclosed in, for example,
As shown in Japanese Patent No. 22484, there are provided a number of drying tanks, a number of storage bins, and a processing device such as a rice huller,
The drying tank supplies dehumidified air dehumidified by an air conditioner to dehumidify and dry the grains carried into the drying tank, stores the dried grains in a storage bin, and stores the grains stored in the storage bin as necessary. After taking out and processing such as hulling, they are packed in bags and shipped.

[0004] In the drying treatment facility configured as described above, a replacement tank is provided separately from the drying tank, and when one dehumidification drying process in the drying tank is completed, the replacement is performed from one of the drying tanks. Replace the grains in the tank, transfer the grains in the other drying tanks to the empty drying tank, transfer the grains in the replacement tank to the last empty drying tank and perform dehumidification drying again. By repeating the
The drying dehumidifying and drying of the grains in each drying tank is performed so as not to cause uneven drying.

[0005]

However, in the above-mentioned drying treatment facilities, since the exchange of grains in the drying tank and the exchange tank is performed by an operator operating a transfer device,
Such work is necessary, and there is a problem that the transfer process management to prevent the deterioration of grain quality becomes complicated, and that the replacement of the drying tank should be performed in a predetermined order. Therefore, even if there is variation in the moisture value of the grains stored in each drying tank, replacement is performed in a certain order regardless of this variation, and as a result, in a drying tank in which predetermined replacement is performed, There were problems such as overdrying and insufficient drying.

SUMMARY OF THE INVENTION It is an object of the present invention to use a large number of storage bins to automatically transfer a dried object from a storage bin into which the object is transported to an empty storage bin by a predetermined rotation. In the case of performing, the transfer can be controlled based on the transfer time set according to the moisture value, that is, the transfer can be performed at short intervals for the storage bin into which the grain having a high moisture value has been brought in, It is an object of the present invention to provide a drying apparatus that can dry the storage bins without drying unevenness and without excess and shortage.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a plurality of storage bins connected to an air supply path for storing the objects to be dried, and loading the objects to be dried into the storage bins. A transfer unit for transferring the object to be dried from the storage bin into which the object to be dried has been transferred to an empty storage bin,
A control device for controlling the transfer of the material to be dried by the transfer device, wherein the control device controls the transfer device to empty the storage bin when the grain stored in the storage bin has a high moisture value. The transfer time is shortened, and when the moisture value of the grain stored in the storage bin is low, the transfer time to the empty storage bin by the transfer device is lengthened.

[0008]

When a dried product of cereal (hereinafter simply referred to as cereal) is mainly carried into the storage bin 10, that is, when a predetermined lot of cereal is brought in from a unit farmer, the cereal is transferred from the storage unit to the storage bin 10 by a predetermined amount. And the grain thus delivered is stored in the storage bin 1
At 0, it is dried by the air supplied to the storage bin 10.

At this time, since a plurality of the storage bins are provided and have a receiving volume much larger than the lot carried in by the unit farmer, there is an empty storage bin at the time of carry-in. .

[0010] Then, the object to be dried carried into the storage bin is dried by air, and then the object to be dried is transferred from the storage bin into which the object to be dried is carried to an empty storage bin.

That is, the storage bin carried in when the object to be dried is carried in, the empty storage bin, and the storage bin emptied by the transfer and the storage bin transferred are sequentially input to the control device. At the same time, the moisture value of the object to be dried carried into the storage bin for the object to be dried and the time when the object is carried are input to the control device.

The designation of a storage bin to be transferred from the storage bin into which the object to be dried is carried out (hereinafter referred to as a bin) is set by setting a transfer time t based on the moisture value of the object to be dried. The storage bin that executes the transfer after the elapse of the transfer time t is designated as the source bin.

That is, the optimum transfer time is determined in advance by an experimental value in accordance with the moisture value and is input to the control device, and the transfer time t is set as a function of the moisture value based on the experimental value. When the moisture value is high, the transfer time t is shortened, and when the moisture value is low, the transfer time t is set long. The bins are sequentially specified based on the transfer time t thus set.

[0014]

[0015] Then, the drive of the transfer device is controlled to execute rotation control for transfer between storage bins.

Therefore, the storage bin 10 having a high moisture value is designated as a departure bin at short intervals as time passes, and rotation control is performed while updating the arrival bin.
Even when the number of empty storage bins 10 is small, the rotation control between the storage bins 10 can be automatically performed, so that it is not necessary to specify the departure bin and the arrival bin each time an operator performs transfer, thereby simplifying the stroke management. In addition, since the transfer rotation control is performed based on the moisture value, the drying can be performed without danger of overdrying or insufficient drying.

That is, the moisture sensor 28 is set on the transport weighing machine 30 so as to measure the moisture value of the grain to be weighed by the weighing machine 30. The weight of one time is set to a plurality of equal weights in consideration of the receiving capacity of the storage bin 10, so that the amount of grain corresponding to the equal weight is continuously stored in the storage bin 10. In addition, since the moisture value of the grain measured by the transport weighing machine 30 is measured by the moisture sensor 28 for each equally divided weight, the water content of the grain is equally divided into the storage bin 10. Grains carried by weight are stacked in layers and the moisture values of each of these layers can be determined.

It is.

The controller 41 has a counter for measuring time, and the moisture sensor 2
8, a transfer time is set based on the detection result from step 8, and when the transfer set time elapses from the time when the grain is carried in, the storage bin 10 for performing the transfer is specified as the release bin. The storage bin 10 designated as the destination bin by the source bin designation unit 45 following the destination bin designation by the means 45 and the keyboard 50 is designated as the destination bin of the next rank when the transfer bin is advanced to the next rank. A destination bin designating unit 49 having a destination bin designation updating unit 51 to be designated is provided.

In the above embodiment, the destination bin designating means comprises the keyboard 50 and the destination bin designation updating means 5.
However, without specifying the destination bin by the keyboard 50, any one empty bin is specified as the destination bin based on the empty bin information from the empty bin detection sensor 27. The destination bin specification may be automatically updated by an operation of the destination bin specification updating unit 51.

On the output side of the controller 41, the transfer devices 12, 13, and 14 are arranged in accordance with the designation order designated by the source bin designation means 45 and the destination bin designation means 49.

The bin designation by the bin designation means 45 is performed after the elapse of the transfer set time t set in advance based on the moisture value stored in the memory (RAM). The setting of the transfer time t is
The moisture value is set as a function based on a reference value α obtained from an experimental value stored in a memory in advance.

Now, as shown in FIG.
No. 1 with storage bins consisting of 10
The case where grain is carried into 7 bins of No. 7 bins will be described.

In this case, each time the grain is loaded into each of the bins No. 1 to No. 7, the moisture value and the loading completion time are initialized, and the previous loading completion time and the moisture value are initialized and newly stored in the memory ( RAM). still,
At the initial stage of loading when receiving from the receiving and weighing machine 5,
The fact that Nos. 8 to 10 are empty bins is also stored in the memory (RAM) under the detection of the empty bin detection sensor 27.

The grains carried in the bins No. 1 to No. 7 are dried by the air supplied from the blower 32.
The transfer time t for each bin is set each time based on the moisture value measured by the moisture sensor 28 in the bins No. 1 to No. 7. Therefore, the current time is read, the elapsed time T from the loading completion time to the current time is calculated, and the storage bin 10 arriving first at the transfer set time t set in accordance with the moisture value is determined to be the bin of rank 1 , And the transfer of the storage bin 10 is executed.

That is, the transfer time t is set based on a reference value α obtained by an experiment using the moisture value W detected by the moisture sensor 28 as a function. The product of the value W and the elapsed time T is
Compared with the reference value α, when the elapsed time T exceeds the transfer set time t and the product of the moisture value W and the elapsed time T exceeds the reference value α, the storage bin 10 is placed in the first rank. Specify the bin and execute the transfer.

The moisture value W is an average value of the moisture values of the respective layers in each bin. Since the moisture value of each layer can be detected in each bin, the moisture value of each layer can be detected. Can also be calculated.

Therefore, the reference value α is corrected based on the coefficient in accordance with the degree of the variation, whereby the average moisture value is equally transferred and set.
Are the same time, it is possible to preferentially designate the storage bin 10 having a large variation as the source bin.

Since the reference value α changes the degree of drying according to the condition at the time of the transfer, the degree of drying after the transfer is performed and the drying operation is performed is considered. Correction is also possible, and thereby, the accuracy of the transfer control can be further improved.

Next, the case where the moisture values of the three layers are detected in the bottles No. 1 to No. 7 and the respective moisture values are distributed as shown in Table 1 will be described in further detail.

[0045]

[Table 1]

In this case, the storage bin 10 having a high water average value is
NO.4 bin, NO.2 and NO.3 to NO.5 bin and N
O.7, NO.1, and NO.6 bins are sequentially lower.

Therefore, in the above-described moisture value distribution, the transfer time t set according to the moisture value of the No. 4 bin having the highest moisture value is set to be the shortest,
If the product of the moisture value (%) constituting the reference value α and the transfer time (minutes) is experimentally set to, for example, 2500, the moisture value W in the No. 4 bin is 290%. The transfer setting time t set according to the moisture value W is 86 minutes, and since the moisture values W of both No. 2 and No. 3 are 24.7%, the transfer setting time is 101.
Minutes.

In the same manner, NO. 5, NO. 7, NO. 1, NO.
The transfer setting time of No. 6 is 104 minutes, 105 minutes and 117
Minutes, 121 minutes.

When the grain is sequentially loaded from the bin 1 to the bin 7 from the receiving and weighing machine 5 into each bin, and when it takes 5 minutes to load the bins into each bin, the bin 4 is used. Is NO.
The loading is completed with a delay of 15 minutes with respect to one bin, and with a delay of 10 minutes and 5 minutes with respect to bins No. 2 and 3, but the transfer setting time t is NO. The four bins are 31 minutes shorter and 15 minutes shorter than the No. 2 and 3 bins.
When starting at 0:00, the No. 4 bin is designated as the first bin in priority order over the No. 1 to No. 3 bins and the destination bin is designated at 11:46 am, 86 minutes after 10:20 am The transfer to the destination bin designated by the means 49, for example, the No. 8 bin is executed.

Next, the transfer setting time t of the No. 2 and No. 3 bins is shorter than the No. 4 bin, and is 16 minutes from the transfer setting time t of 117 minutes of the No. 1 bin. Short 10
Since it is 1 minute, first, the No. 2 bin is designated as the rank 2 departure bin, and the transfer to the No. 9 bin is executed at 11:51 am after 101 minutes from 10:10 am Then, the No. 3 bin is designated as the bin of rank 3 and the 11th morning after 10:15 am and 101 minutes has passed.
At time 56, for example, transfer to the No. 10 bin is executed.

In this case, if the time required for the transfer is, for example, 10 minutes, the transfer of the next order is executed after the completion of the transfer of the first order, and the above-mentioned NO. 2 and NO.
Although the moisture value W of the three bins is the same, since the variation of the moisture value in each layer of the No. 3 bin is larger than the variation of the No. 2 bin, the reference value α for the No. 3 bin is changed according to the degree of this variation. Corrected and its transfer setting time t
Is shorter than the No. 2 bin transfer setting time t, the No. 3 bin is designated as the rank 2 departure bin, and the No. 2 bin is transferred to the No. 9 bin prior to the No. 2 bin. Will be done.

Next, the water content W of the No. 5 bin and the No. 7 bin
Is higher than the water value W of the No. 1 bin, but the difference in the time of completion of loading is 20 minutes in the No. 5 bin and 3 in the No. 7 bin.
Since there is 0 minutes, the No. 1 bin is designated as the rank 4 departure bin, and at 12:02 am, the destination bin specified by the destination bin designating means 49, that is, the destination bin is specified first, The transfer is executed to the bin No. 4 where the transfer has been completed, and then the bin No. 5 is designated as the departure bin of the rank 5 and the bin No. 2 or No. 3 at 12:09 am Transfer is performed.

In the No. 6 bin, grain is carried in before the No. 7 bin. However, the moisture value W of the No. 7 bin is higher than the moisture value of the No. 6 bin, and the transfer setting time t is , No. 6 is shorter than No. 6, so the No. 7 bin is designated as the departure bin of rank 6, and at 12:15 am, transfer to No. 3 or No. 2 is executed. The 6 bins are finally designated as the 7th outgoing bins, and the transfer to the 5th bin is performed at 12:30 AM. The transfer setting time t of the No. 6 bin is 121 minutes. However, when the moisture value W is low, for example, when the moisture value W is 21% or less, once every two hours regardless of the moisture value W. Therefore, the minimum transfer time is set so as to execute the transfer, and accordingly, the bin No. 6 executes the transfer after a lapse of 120 minutes.

In any case, the higher the moisture value, the shorter the interval between transfers, and if the moisture value is the same, the greater the variation in the moisture values in each layer, the shorter the interval between transfers. When the moisture value is low, the transfer interval is long. In any case, when the product of the moisture value W and the transfer set time, that is, the elapsed time T exceeds the reference value α, the transfer is performed. When the moisture value W is low, for example, when the moisture value W is 21% or less, 2
The transfer will be performed once a time. When the transfer of the storage bin 10 having a low moisture value W is performed,
When the storage bin 10 having a high moisture value W reaches the transfer set time, the storage bin 10 is executed with priority by interruption.

The destination bin designation by the destination bin designating means 49 is performed only when the first transfer is performed, or when the number of empty bins is large. Looking at the image display by 48,
It is manually set by the keyboard 50, but thereafter, when the storage bin 10 designated as the departure bin by the departure bin designation means 45 by the destination bin designation update means 51 advances to the next rank of the transfer rank, That is, the destination bin of the next rank is designated.

Next, the operation of the rotation control mechanism 40 configured as described above will be described with reference to the flowchart shown in FIG.

In step 1 after the start, the previous loading completion time and the moisture value in each storage bin 10 into which the grain has been loaded are initialized. Then, in step 2, the carry-in completion time Z carried in by the previous transfer execution and the carry-in completion time Z when first carried in from the receiving side, and the moisture value from the moisture sensor 28 at the time of carry-in are stored in the memory. (RAM).

In step 3, an average moisture value W is calculated based on the moisture value, and based on the average moisture value W, a transfer time t of the loaded storage bin 10 is set. , The bottle 1 based on the moisture value
A variation of 0 is calculated, and the reference value α is corrected based on a coefficient corresponding to the degree of variation. When the degree of variation is large, the transfer setting time t according to the moisture value W is corrected to be short.

The current time is always read, and the elapsed time T from the loading completion time Z of each bin is calculated based on the current time G (step 4), and the transfer set time set in step 3 is set. The originating bin is specified based on t (step 5), and the destination bin is specified based on the destination bin specifying means 49. (Step 6) Then, in Step 7, the product of the moisture value W of each bin and the elapsed time T is compared with a reference value α (for example, 2500 described above). The replacement is performed. (Step 8) In addition, the execution of this transfer is performed by the counter C
It is determined in step 10 whether or not the number of transfers counted in step 9 is equal to or greater than the number of transfers M in the preset rotation control. In this case, the process returns to step 1 and the previous transfer completion time (10:20 AM in the above description) and the moisture value W (in the above description, for example, in the No. 4 bin of rank 1 where the transfer was executed). 29%) to clear and initialize,
In step 2, the transfer completion time Z and the moisture value W after execution of the new transfer are stored.

When the transfer of the rank 1 is performed as described above, the product of the moisture value W and the elapsed time T in the bin 2 of the rank 2 or the bin 3 of the rank 2 is compared with the reference value α. When the value exceeds the reference value α, the transfer of the rank 2 is executed by the above-described procedure after the completion of the transfer of the rank 1, and the transfer is similarly set according to the moisture value W thereafter. It is executed in accordance with the lapse of the replacement time t and the lapse of the minimum time.

When the number of transfers becomes equal to or more than the preset number of times M due to the repetition of the above transfer, the rotation control for bins No. 1 to No. 7 is completed. (Step 11) As described above, the storage bin 10 into which the grain having the highest moisture value W is carried in and the grain having the lowest moisture among the grains carried in from the receiving and weighing machine 5 within the range of the set number of times M are carried in. Although the number of transfers with the storage bin 10 may be different, the transfer time of the storage bin 10 into which the grain having a high moisture value is transferred is set to be short, and the empty storage bin 10 is set.
Therefore, while the grain can be automatically transferred in a predetermined rotation, each storage bin 10
Drying can be performed without unevenness and without excess or shortage.

In the above-described embodiment, the air conditioner 31 is used to supply the dehumidified air to the supply path 11, but the air may be used as it is without using the processing air. Good.

[0063]

According to the present invention, as described above, a large number of storage bins 10 are used, and among these storage bins 10, empty storage bins 10 are used to store the storage bins 10 into which the objects to be dried are carried.
Can be automatically transferred to the empty storage bin 10 by a predetermined rotation, and therefore, the transfer process can be easily controlled, and the transfer is set based on the moisture value. Since the transfer is controlled at a short interval with respect to the storage bin 10 into which the grain having a high moisture value is carried in, the storage bin 1 is controlled by the change time.
At 0, the object to be dried can be dried without unevenness in drying and without excess or shortage.
