Abstract

PURPOSE:To carry out an even dying through an entire lot by enabling even drying in individual bins as a whole of one machine without causing uneven drying partly among grain particles placed into the storage bottles per machine and further a pevention of uneven drying between the storage bins. CONSTITUTION:A carry-in weighing device 19 is provided between a feeding lift 12 for grain loaded and a relay conveyor 13 to weigh the grain by a small amount at a time and also, a moisture detector 20 to detect the moisture value thereof. The grain is carried into different bins 10 from a top conveyor 14 being classified as 'wet', 'half dry' and 'dry' according to the attribute of moisure in the grain. A damper 25 of the bins in high moisture zones is made larger in opening to increase the amount of air to be supplied and the damper 25 in lower moisture zones smaller to reduce the amount of air to be supplied thereby accomplishing proper drying according to the moisture.

2. Description of the Related Art Conventionally, a drying device of this type has been disclosed in Japanese Patent Laid-Open No.
As disclosed in Japanese Unexamined Patent Publication No. 122485, a large number of storage bottles for storing grains, a large number of drying tanks for drying grains, and a single replacement tank are provided. After finishing the drying process of, the grain from one of the drying tanks is once transferred to the replacement tank, the grains of other drying tanks are sequentially transferred to the empty drying tank, and finally the empty drying tank is replaced. The grain in the tank is transferred, and then dried again, and the drying by such transfer is repeated several times, and the moisture of the grain is detected by the moisture sensor during transfer, and when the water content falls below a specified level, residual drying is performed. Time is calculated, the drying process is terminated after the time has elapsed, and air is supplied to the grain without excess or deficiency to prevent excessive drying and insufficient drying.

However, in the above, the moisture sensor is used, and the moisture sensor detects the moisture content of the grain for each drying tank and sets the drying time according to the moisture content. Although the total air volume supplied to the grain can be adjusted, the grain that is initially loaded into each drying tank is packed with grains with different moisture contents mixed in the first place, so the amount of air supplied to each drying tank can be adjusted. The adjustment is not sufficient, and the grain portion originally having a low water content tends to be overdried, and the grain portion originally having a high water content tends to be insufficiently dried.

Then, in step b, the carry-in weighing device 19 measures 5 kg at a time, and in step d, the moisture value is detected by the moisture detector 20. In steps d-1 to d-3, the group identifier G is determined according to the classification of Table 1. "1" or "2" or "3"
Is substituted. Now, if the moisture value is 22% or more, G = 1. Subsequently, in step e, “1” is stored in the bin number index n, and in step f, NO. The moisture classification data B1 corresponding to 1 is "0", that is, NO. If 1 is still empty and the incoming grain is the first one, step g. Step 1 after loading the grain into 1
In step i, the group identifier G = 1 is stored in B1. "1" is added to the carry-in weight data M1 corresponding to 1, the bin number index n is cleared to "0" at step j, and the procedure returns from step k to step b to perform the next weighing.

It is determined that the grain belongs to the same moisture classification as the grain that has already been carried into No. 1 and NO in Step p. 1 is the level sensor 2
This NO. The imported grain is added to the item 1 and is imported, and the process is returned to step b again.

The moisture value of the next measured grain is, for example, 20%.
If so, G = 2, which contradicts B1 = 1. Therefore, 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 grain is carried into No. 2, G = 2 is stored in B2 in step h, and NO in step i. "1" is added to the carry-in weight data M2 of 2, and the process returns from step k to step b to perform the next weighing.

Next, when the one-step drying process is completed, the process proceeds from step x to step y, and the rotation control according to the loading / unloading bin as shown in Table 2 is performed.
Each rotation results in the state of each bin as shown. At this time, at the same time, the water classification data Bn of each bottle
Is re-stored in the receiving bottle side so that the air flow rate can be controlled according to the water content of each bottle even during the second drying process. In this example, the rotation is performed three times, and one rotation is completed by transferring the ranks 1 to 7 each time.
Empty bottle NO. Is the number of the storage bin that becomes empty when the transfer of the rank 7 is completed in each rotation.

In the above embodiment, the supply air volume is controlled by adjusting the opening of the electric damper 25. However, the opening time of the electric damper 25 is not adjusted and only the opening / closing control is performed, so that the opening time for a bottle having a high water content can be controlled. It is also possible to shorten the opening time for a long bottle having a low water content and change the air blowing time to control the amount of air supplied to the bottle to a large or small value. Further, even if air is sequentially blown individually to the bins classified into different water content groups, the rotation speed of the fan 24 is controlled so as to correspond to the water content level of the group which actually blows air.

As described above, according to the present invention, the sorting / carrying-in means 45 packs a predetermined amount of the material to be dried into the storage bins 10 corresponding to the moisture content of the storage bins 10.
0 Drying unevenness does not occur in the part of the material to be dried packed per one machine, uniform drying can be performed in the entire bottle of one machine, and the air volume control means 48 increases the supply air volume for those with high water content classification. Since the amount of supplied air is controlled to be small for those with a low water content classification, it is possible to perform a drying process according to each water content classification and prevent uneven drying between the storage bottles 10 as a whole. It is possible to prevent insufficient dryness, and to perform good drying.
