Field of the Invention The present invention relates to a co-drying facility for cereals, in which a sample cereal extracted from each cereal brought individually or by consignee is subjected to the same drying conditions. The present invention relates to an automatic drying device for sample grains which is dried to a constant moisture value by using the following method. 2. Description of the Related Art Conventionally, a sample grain drying apparatus used in a joint grain drying facility is disclosed, for example, in Japanese Utility Model Publication No. 60-2.
As described in US Pat. No. 557, it is already known before the present application. [0003] By the way, in the conventionally known apparatus for drying sample grains, a large number of sample drying boxes are provided in the dryer so that each sample drying box can be freely inserted and removed. Must be stored separately in each sample box and put in and out of the dryer, and in the drying work of sample grains handling a large number of sample grains, taking in and out of sample grains and drying management are extremely complicated. In addition, since drying cannot be started unless all sample boxes are loaded into the dryer, waste of sample grains less than the number required to use all the drying boxes is wasteful. Problems, such as poor work efficiency and low work efficiency. Accordingly, the present invention provides a method of sequentially moving and circulating a large number of sample boxes in a chain, and circulating dry hot air through the sequentially moved and circulated sample boxes. The present invention provides an automatic sample grain drying apparatus that can automatically and smoothly take out even a large number of sample grains to a predetermined moisture value by discharging the sample grains when the sample grain reaches a predetermined value. Aim. Means for Solving the Problems The present invention has the following technical means for solving the above problems. That is, the configuration is such that a feed device that sequentially moves and circulates a large number of sample boxes with an open top surface and a bottom surface that is air permeable, and a hot air supply device that circulates dry hot air through the sequentially moved and circulated sample boxes. The sample cereal in each sample box is detected during the moving circulation and is dried to a predetermined moisture by detecting the water content of the sample cereal in each sample box. An automatic drying apparatus for sample grains, characterized in that the sample grains are automatically taken out at a fixed position during the period. When the drying device is moved, a large number of sample boxes are sequentially moved and circulated in a chain by the feeding device. Therefore,
If the sample grains extracted from the grains brought in individually or by the consignee are sequentially stored in each moving and circulating sample box,
Dry hot air from a hot air supply device flows upward from the bottom through each of the moving and circulating drying boxes, and the sample grains in the drying box are dried by the hot air. Then, when the sample grains in each of the moving and circulating sample boxes are dried to a predetermined moisture, the sample grains are automatically extracted from the sample boxes between the moving and circulation start position of the sample box and the position that has passed through the hot air supply device. Is taken out. As described above, even when a large number of sample boxes are moved and circulated to continuously dry a large number of sample grains, the sample boxes are supplied with the sample grains at the starting position of the movement and circulation of the drying box, and each sample box is supplied. The dried sample grains are removed from each sample box between the position where the sample grain is supplied and the hot air supply device that is away from the supply position of the sample grain at the beginning of circulation. This complicates the supply and removal of the sample grains. It can be performed smoothly and efficiently without any problem. [0007] In the apparatus provided with a cold air supply device for flowing cold air upward from the bottom surface of the sample box passing through the hot air supply position from the hot air supply device to float the sample grains, the sample grains in the sample box are cooled by the cool air. By swinging by the blowing action, the accumulation density of the sample grains in the sample box is made uniform, and the moisture of the dried sample grains can be detected with high accuracy. As a result of the moisture detection, if the sample grain has not been dried to a predetermined moisture value, the drying box is moved and circulated again, dried by hot air, dried, and taken out. An embodiment of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a dryer main body, on which a moving circulation path 2 for moving and circulating a large number of sample boxes 3 in a rectangular shape is configured. Each sample box 3
Has a configuration in which the upper surface is open and the bottom surface is a gas permeable surface. A large number of sample boxes 3 are arranged side by side in the moving circulation path 2 with a space corresponding to one box. And the rectangular moving circulation path 2
In the four corners, air cylinders 4a, 4b, 4 which push the sample box 3 sequentially, that is, in directions orthogonal to each other.
c, 4d are provided, by which
Is configured. Reference numeral 6 denotes a hot-air supply device, and 7 denotes a cool-air supply device. The hot-air supply device 6 and the cold-air supply device 7 divide a duct 8 that straddles the moving circulation path 2 into two parts, and a hot-air blower using electric heat is provided below each. 9 and cold air blower 10
The air outlet 11 of the hot air blower 9 opens below the moving circulation path 2, and the hot air side of the duct 8 is connected to the hot air duct 12. On the other hand, the air outlet 13 of the cool air blower 10 opens below the moving circulation path 2, and the cool air side of the duct 8 is connected to the cool air duct 14. Reference numeral 15 denotes an outlet for a dried sample. The bottom surface of the sample box 3 is such that a bottom plate 16 made of a perforated plate can be freely inserted and removed. A is the start end position of the moving circulation path 2, B is the end position, and at the end position B, the water content of the sample grains in the sample box 3 is detected. Then, the sample grains in the sample box 3 are taken out from the outlet 15 and the number of the sample code is read. In the embodiment shown in the drawing, in the moving circulation path 2, the moisture of the sample grains in each sample box 3 is detected and dried to a predetermined moisture, so that the sample grains in the sample box 3 are moved to the sample box 3. It is configured to automatically take out at a fixed position between the moving circulation start end position A and the position where the hot air supply device 6 has passed, that is, the end position B. The moving circulation start end position A and the end position B of the sample box 3 are provided on the same side. For this reason, it is possible to easily take out and put the sample box 3 continuously. The means for detecting the water content of the sample grain is, for example, a conventionally known water content detection means for sampling a small amount of the sample grain and detecting the water content by means of electric resistance, or a method for detecting the change in the dielectric constant of the sample grain due to the water content. There is a conventionally known moisture detecting means for detecting the moisture of the sample grains in the sample box 3 by utilizing. As means for taking out the sample grains from the sample box 3, the bottom plate 1 of the sample box 3 as shown in the illustrated embodiment is used.
In addition to a configuration in which the bottom surface is opened by automatically extracting the sample box 6, the sample box 3 is a conventionally known sample grain taking-out means such as turning the sample box 3 upside down. It is also possible to arrange a suction duct provided with a suction air blower below the moving circulation path 2 so as to suck and dry the sample in the sample box 3 during the movement circulation. Further, in the illustrated embodiment, the moving circulation path 2 is provided on the dryer main body 1 in a planar shape, but the present invention is not limited to this, and the moving circulation path 2 is configured on the dryer main body 1 in the vertical direction. You can also. In the automatic dryer for sample grains configured as described above, to store sample grains in each sample box 3,
Injection is sequentially performed at the start A position of the moving circulation path 2 in accordance with the intermittent timing by the feeding operation of the feeding device 5. In the course of the sequential movement and circulation of the sample box 3, the grains in the sample box 3 are dried by the flow of hot air at the hot air supply position from the hot air supply device 6, and then the cool air supply position from the cold air supply device 7. The rocks are swung in response to the cool air blown up from below, and the accumulation density is equalized. Each sample box 3 is located at the end B of the moving circuit 2
When the water reaches the position, the moisture of the sample grain is detected by the moisture detecting means.
The bottom plate 16 is automatically removed by the sample grain removing means,
The sample grain is taken out from the outlet 15 and the number of the sample code is read. As described above, the sample grains are simply and sequentially stored at the start end A of the moving circulation path 2 in a large number of sample boxes 3 moving and circulating in the moving circulation path 2, and the drying of the sample grains is performed automatically and continuously. Therefore, a large number of sample grains can be easily and efficiently dried to a predetermined moisture value. Also,
At the time of detecting the moisture content of the sample, since the sample grains in the sample box 3 have the same accumulation density, the moisture can be detected with high accuracy. According to the present invention, an effect is obtained in which even a large number of sample grains can be continuously dried smoothly and efficiently and automatically dried to a predetermined moisture value and taken out.
