As disclosed in Japanese Patent Publication No. 122485, the system includes a number of storage bins for storing grains, a number of drying tanks for drying the grains, and a single replacement tank. After finishing the drying process, transfer the grains from one of the drying tanks to the replacement tank, transfer the grains from the other drying tanks sequentially to the empty drying tank, and finally replace the empty drying tank. The grain in the tank is transferred, and then dried again.Drying by such transfer is repeated several times.At the time of transfer, the moisture of the grain is detected by a moisture sensor. The time is calculated, the drying process is terminated after the elapse of the time, and the wind is supplied to the grain without excess or shortage to prevent overdrying and insufficient drying.

燥不足気味となる問題がある。However, in the above, a moisture sensor is used, the moisture sensor detects the moisture content of the grain for each drying tank, and the drying time is set according to the moisture content. Although the total air volume supplied to the grains can be adjusted, the grains initially brought into each drying tank are packed in a state where grains having various moisture contents are mixed in the first place. Even if the adjustment is not enough, there is a problem that the grain portion having a low moisture content tends to be over-dried and the grain portion having a high moisture content originally tends to be under-dried.

It is an object of the present invention to provide a grain drying apparatus capable of effectively preventing overdrying and insufficient drying of grains and the like in each storage bin by controlling the size of the grain.

Is assigned. Now, if the moisture value is 22% or more, G = 1. Subsequently, "1" is stored in the bin number index n in step e, and NO. 1 is "0", that is, NO. If No. 1 is still empty and the incoming grain is the first one, NO. Step 1 after loading the grain into
The group identifier G = 1 is stored in B1 at step i. "1" is added to the carry-in weight data M1 corresponding to 1, and the bin number index n is cleared to "0" in step j, the process returns from step k to step b, and the next measurement is performed.

In step f, since B1 = 1 and not 0, the process proceeds to step o, where G = B1 = 1, that is, NO.
1 is determined to be a grain belonging to the same moisture classification as the grain already carried in, and in step p, NO. 1 is level sensor 2

In this case, G = 2, which contradicts B1 = 1, so a negative determination is made in step o, the process proceeds to step m, the bin number index n is updated by 1, and then the process returns to step f.
Since B2 = 0 here, NO in step g. After the cereal is carried in to step B, G = 2 is stored in B2 in step h, and NO. "1" is added to the carry-in weight data M2 of No. 2 and the process returns from step k to step b to perform the next weighing.

After the cereal is loaded into B3, G = 3 is stored in B3 in step h, and NO. "1" is added to the carry-in weight data M3 of No. 3 and the process returns from step k to step b to perform the next weighing.

After the grain is added to and transported to B2, G = 2 is stored again in B2 in step h, and NO. "1" is added to the carry-in weight data M2 of No. 2 and the process returns from step k to step b to perform the next weighing.

When the bin number index n is updated to 4 in step m, the process proceeds from step f to step g, and in this step g, NO. Then, the cereal is loaded into B4, G = 1 is stored in B4 in Step h, and Step i is performed.
Then, "1" is added to M4, the process returns from step k to step b, and the next measurement is performed.

Then, the drying process under the next air volume control is executed. That is, in step s, the opening of the electric damper 25 in the wet group bins (NO. 1, 4, and 5 in the illustrated example) is increased, and in step t, the semi-dry group bins (NO.
Step u during the opening of the electric damper 25 in the steps 2 and 6).
And the opening of the electric damper 25 of the bins (NO. 3, 7) of the drying group is small, and the empty bins (NO. 8, 9, 1)
The electric damper 25 of (0) is controlled to be closed, and the air conditioner 23 and the fan 24 are driven in step w to blow air with dehumidified air. In this manner, the supply air volume is controlled to be large for grains having a high moisture classification, and the supply air flow is controlled to be small for grains having a low moisture classification. This can prevent uneven drying.

Each bin is in the state as shown in the figure by the rotation of one time. At this time, at the same time, the moisture classification data Bn
Is stored again on the receiving bin side, so that even at the time of the second drying process, the air volume can be controlled according to the moisture classification of each bin. In this example, the rotation is performed three times, and one rotation is completed by shifting the ranks from 1 to 7 each time.

き、良好な乾燥が行えるのである。As described above, according to the present invention, the objects to be dried of a predetermined amount are packed in the storage bins 10 by the distribution carrying means 45 in accordance with the moisture classification.
0 Drying can be performed uniformly in the entire bottle of one machine without causing drying unevenness in the portion of the material to be dried packed per machine. Since the supply air volume is controlled to be small for those having a low moisture classification, drying processing can be performed in accordance with each moisture classification, and uneven drying between the storage bins 10 can be prevented. And insufficient drying can be prevented, and good drying can be performed.
