Description

[0001]
[Industrial application fields]
In particular, the present invention relates to a grain drying storage facility for drying and storing grains using a large number of grain storage bins.
[0002]
[Prior art]
Conventionally, various grain drying and storage facilities have been proposed in which grains from individual producers are collected and dried and stored, and after processing such as hulling, the necessary adjustments are made and shipped. This grain drying storage facility is called an A-type country elevator, a B-type country elevator, a C-type country elevator, etc., and the facilities have been mainly constructed for thermal drying, although the receiving method and the drying method are different. In recent years, facilities have been developed in which dehumidifiers have been applied to grain drying instead of thermal power, and have been widely accepted and accepted by consumers for good taste and safety.
[0003]
For example, Japanese Patent Laid-Open No. 3-122484 includes a large number of storage bins and processing devices such as a hulling machine, and the drying bins are supplied with dehumidified air dehumidified by an air conditioner to dehumidify the grains carried into the drying bins. It has been proposed to dry and store dried grains in storage bins, take out the grains stored in storage bins as necessary, treat them with rice hulls, and then ship them by bagging. ing.
[0004]
This drying treatment equipment eliminates the disadvantages of conventional thermal drying, but there may be a difference in moisture between the upper and lower layers of stored grains during drying, especially in large drying facilities, Is about 50 tons per bottle, and the height of grain accumulation may be 5 m or more, so that uneven drying tends to occur. Therefore, normally, a replacement bottle is provided separately from the drying bottle, and when one dehumidification drying process in the drying bottle is completed, the grain is replaced from one of the drying bottles to the replacement bottle, and the drying becomes empty. Transfer the grain from the other dry bottle to the bottle, replace it with the dry bottle that was emptied at the end, perform the so-called rotation work to transfer the grain from the bottle, mix the lower layer well dried grain and the upper layer slow dry grain, Thereafter, dehumidification drying is performed again to make the moisture uniform. This operation is repeated a plurality of times to prevent uneven drying in the dehumidification drying of the grains in each drying bottle.
[0005]
However, in the dry storage facility as described above, a large number of storage bins and replacement bins are indispensable in addition to a large number of dry bins. Has become a heavy work. Although the rotation capacity depends on the discharge capacity by wind, the discharge capacity in a normal dry storage facility is 20-30 tons per hour, and it takes 2-3 hours to empty one 50-ton bin. For example, in the case of a facility having several series of 10 or more bins per series, this rotation work alone may result in one day.
[0006]
In order to solve the inconvenience, a dry grain storage facility that does not require a rotation work as shown in FIG. 4 has also been proposed (see, for example, JP-A-7-103648). In the figure, 1 is a load receiving hopper for picking up grains, 2 is a load receiving lift, 4 is a coarse sorter, and 5 is a weighing machine. Through the conveyor 11, the same bins (A1 to A7 rows and B1 to B7 rows) are sequentially supplied with the same thickness. The lower part of each bin row forms a dehumidified air supply path (drying air blowing duct) P, which is connected to the air conditioner 20 and the blower 21 and is supplied with dehumidified air, Accompanying the drying of grains in each bottle. Reference numeral 13 denotes a grain inlet with an on-off valve. A discharge conveyor 12 is provided below the bin rows A1 to A7 and B1 to B7, and processed grains are transferred from the discharge conveyor 12 to the adjustment tank 6, the selective weighing equipment 7, the hulling adjustment plant 8, the shipping tank 9, and the like. A grain unloading section is provided. This processing facility is characterized in that each bin (A1 to A7 and B1 to B7) is equipped with a stirring device 100 capable of stirring the grain to be stored at least in the vertical direction. In the figure, reference numeral 14 denotes a grain outlet with an on-off valve.
[0007]
In this grain dry storage facility, the grains in each storage bin are always agitated at least in the vertical direction by the agitator 100, and supply of dehumidified air without performing a so-called rotation operation as in the conventional grain dry storage facility. The desired drying process can be completed without causing uneven drying of the grains in the bottle during the drying process. Further, the grain after the drying process can be stored in the bin as it is, and the idle bin can be eliminated, thereby reducing the cost of the facility cost and the maintenance cost as a whole. Further, the loss of air volume due to rotation can be prevented, and the entire amount of dehumidified air can be involved in drying.
[0008]
[Problems to be solved by the invention]
As described above, in the case of a facility that requires rotation work, there is an inconvenience that it takes too much time for rotation, and it is essential to secure a replacement bin (rotation bin) separately from the dry bin. In the ton processing facility, it was necessary to install 50 ton bins exceeding 70 bins. In addition, if you want to be able to receive and rotate at the same time, it is necessary to increase the number of weighers because the weighing is duplicated. In addition, there is a disadvantage that it takes a long time to work.
[0009]
In addition, in the case of the dry storage facility in which all the bottles are equipped with a stirrer, the number of bottles is reduced compared with the facility of the rotation system. As an example, if the variety composition becomes multi-variety, the amount of one variety is not necessarily 50 tons, so the required number of grain storage bins may exceed 60 bins, and all bins When a stirrer is installed, the initial cost including the control panel tends to increase. In addition, normally, one stirrer is equipped with three electric motors, and the running cost when the power is concentrated to operate all units at one time can be reduced. In addition, since there are many drive units, there is mechanical wear, and the maintenance and inspection of the worker must be a large amount of work.
[0010]
The present invention is to provide a new grain drying storage facility that solves the above-mentioned disadvantages of conventional drying storage facilities, and more specifically, a grain storage bin (for example, stirring) that increases the complexity of operation. It is an object of the present invention to provide a grain drying storage facility capable of supplying a new drying storage system capable of maximizing the dehumidifying drying capacity while reducing the number of grain storage bins equipped with devices and reducing maintenance labor.
[0011]
[Hand throws to solve problems]
The grain dry storage facility according to the present invention for achieving the above object basically includes a grain carry-in section, a number of grain storage bins for drying and / or storage of grains, and air is supplied to the grain storage bins. In the grain dry storage facility comprising an air supply means for feeding and a carry-out unit for carrying out the processed grain, the multiple grain storage bins can stir the grains to be stored at least in the vertical direction. A first grain storage bin group, and a second grain storage bin group used for temporary storage of semi-dry grains dried to semi-dry moisture in the first grain storage bin group and storage of dry grains; And each grain storage bin constituting the second grain storage bin group has a larger capacity than each grain storage bin constituting the first grain storage bin group. .
[0012]
For example, in the case of rice, the harvested rice that has been received is first dried with a moisture content of 24% to 17% as the initial drying, and then the semi-dried grain that has been primarily stored has a specified moisture content of 16 to 14.5%. It is finished and dried to the following, and is selected and weighed as necessary. (Note that 24% of this is due to the fact that the Ministry of Agriculture, Forestry and Fisheries uses 24% of the planned treatment water for harvested rice, and 17% This is because the ministry has determined that the short-term primary storage can be safely done within 35 days with no ventilation at 17% or less). Therefore, in the present specification, the term “semi-dry moisture” refers to a moisture content of about 17% in the above sense, and the term “semi-dry grain” refers to a moisture content of about 17% in the sense of the above. The term "finished dry" means that the grain that has become 17% in the above sense is dried to a specified moisture content of 16-14.5% or less. Means the grain in a state of being finished and dried to a specified moisture content of 16 to 14.5% or less in the above sense.
[0013]
In the grain dry storage facility according to the present invention, when the grain is brought into the facility from the grain producer, the grain is sequentially fed from the grain carry-in section into the grain storage bin provided with the stirring device constituting the first grain storage bin group. Is done. Each of the grain storage bins constituting the first grain storage bin group is connected to an air supply path having an air supply means for supplying air, and the supplied air is used in the case of a conventional grain dry storage facility. Similarly, grains are subject to drying. In the present invention, each grain storage bin is provided with a stirring device capable of stirring the stored grain at least in the vertical direction, and the grains in the grain storage bin are dried during the drying process. Is stirred up and down equally over the entire area. Therefore, the grains stored in the storage bins can be stored without changing the grains (rotation work) between the storage bins or between the drying tank and the replacement tank as in the conventional grain drying storage facility. Uniform moisture dried in equal proportions in the bottle, and no uneven drying occurs in the dehumidification drying of the grains in the same storage bin.
[0014]
In a preferred embodiment, the air supply means includes an air conditioner including a dehumidifier and a blower, and dehumidified air can be supplied from the air supply means to at least the grain storage bin provided with the stirring device. It is said that. For this reason, the carried grain is uniformly dried even in a semi-dry moisture state.
In a preferred aspect, the first grain storage bin group is further provided with a grain storage bin not provided with a stirring device. In addition to the functions of the primary storage of semi-dry cereals and storage of dry cereals described later, this can also be used for drying when the amount of high moisture cereals received per day exceeds the design amount. It is for doing so.
[0015]
Hereinafter, as an example of facility design, for example, a case where processing is performed in a four-day cycle with a three-day receipt and a one-day cancellation date will be described in detail. In this case, the grain received on the first day is evenly stretched into one-third of the total number of dry storage bins having the stirring device. Grain received on the second day will be stretched to the other one-third of free bins, and grain received on the third day to the remaining one-third bin. Is included. Grain that has been put in is gently dried without moisture unevenness by uniform stirring by the stirring device and dehumidifying air. The fourth day is a day when the receipt of goods is suspended, and each bottle is only dried.
[0016]
On the 5th day, the grain put in on the 1st day is uniformly dried to the semi-dry moisture state, and the semi-dry grain is sent to the grain storage bins constituting the second grain storage bin group. . Grains loaded on the fifth day are equally put into the bins emptied by discharging the grains to the second grain storage bin group by the same operation again. Thereafter, this operation is repeated every day. After the required number of days have elapsed, the second grain storage bin group is full. Thereafter, if the first grain storage bin group is provided with a bottle that does not have a stirring device, the semi-dry grain that has been in a semi-dry moisture state is also uniformly charged into the bottle until it is full.
[0017]
In the grain dry storage facility according to the present invention, each grain storage bin constituting the second grain storage bin group has a larger capacity (preferably doubled) than each grain storage bin constituting the first grain storage bin group. Therefore, in addition to reducing the number of grain storage bins constituting the second grain storage bin group, the first grain storage bin and the second grain storage bin have the same flat area. In the case where the capacity is determined by the bin height, the arrangement of the bin rows can be rationally configured, and the flat area of the bin group rows is reduced, so that the construction cost can be reduced. There is merit such as being able to plan.
[0018]
Thereafter, charging is repeated evenly on the first day, the second day, and the third day with respect to the dry storage bin having the stirring device, and cumulative mixing stirring drying is performed there. As described above, the cumulative mixing stirring drying is also performed on the fourth day. By repeating this process, the facility can receive the whole amount of the designed grain load, and can dry moisture uniformly and evenly until it is semi-dried. In addition, since the cumulative mixing stirring drying described above, which started from the last stage of receiving and drying, can be dried to the specified finishing drying in the same bottle, the cumulative mixing stirring drying is performed as it is in consideration of the ease of operation and the energy to be repelled. It is desirable to proceed to finish drying.
[0019]
Next, finish drying of the grain made into the semi-dry moisture state as described above is performed. In the finish drying, the first grain storage bin group is provided with a bin equipped with an empty stirring device for the first grain storage bin group from the beginning, and the first grain storage bin group and the second grain storage bin not having at least the stirring device are provided in the bin. Semi-dry cereals stored in grain storage bins will be transferred sequentially. In another method, the capacity of each grain storage bin constituting the first grain storage bin group from the beginning is somewhat larger (for example, in the case of 50 ton bins, the size can be deposited to about 56 tons by natural input). ) Dried grains in one of the multiple bottles with agitator that had been made and finished to dryness by continuing cumulative mixed stirring drying were divided into other agitator-equipped bins. And securing a single empty bin with an agitator, and a bin having no agitator in the first grain storage bin group and a second grain storage bin in the empty bin The semi-dried grains stored in the group are sequentially transferred to finish drying. After finish drying, the dried cereal is returned to its original bottle. By repeating this operation, the semi-dried stored grains are finished and dried in a short time and stored.
[0020]
As described above, in the case of the grain drying storage facility according to the present invention, the finishing drying is performed by cumulative mixed stirring drying, so there is almost no operation of the facility, and only monitoring is the main job, which can save personnel. In addition, the bottle having the stirring device in the first grain storage bin group can be used for both the drying bottle and the storage bottle, the operation efficiency of the whole grain drying storage facility is high, and there is no waste in storage. It can be provided as a facility that can be operated at low cost.
[0021]
Further, the drying of the high moisture content grain to the semi-dry moisture and the finish drying are performed in the bin having the stirring device in the first grain storage bin group. Therefore, it is preferable that dehumidified air is sent from the air supply means to the bottle having the stirring device. However, in the first grain storage bin group that does not include the stirring device and the grain storage bin that constitutes the second grain storage bin group, the primary storage of the semi-dry grain and the storage of the dry grain are only performed. Yes, it is not always necessary to send dehumidified air. Therefore, it is only necessary to supply air to the bins with an air volume necessary for discharging stored grain, and energy saving as a whole facility can be achieved.
[0022]
In the present invention, when the first grain storage bin group is provided with a grain storage bin not equipped with a stirring device, as described above, the amount of high moisture grain received per day was brought in more than the designed amount. In addition to being able to be used for drying, there is a merit that a grain carrying-in part, an air supply path, a grain carrying-out part, etc. can be made common.
It should be noted that in the grain storage bin connected to the air supply path, the grain storage bin having the stirring device and the grain storage bin not having the stirring device, the air is removed by means such as closing the shutter after the drying process is completed or when necessary. As in the case of a normal dehumidifying and drying facility, the connection with the supply path is cut off and it can be used as it is as a grain storage bin as described above.
[0023]
Preferably, the grain storage bins constituting the first and second grain storage bin groups are arranged in multiple rows, and the grain loading and unloading portions are arranged on one side in the longitudinal direction of the row groups. The air supply means is disposed on the other side, and a bin loading conveyor is disposed above the row group and a discharge conveyor is disposed below. This makes it possible to carry in necessary grain, put it into a storage bin, discharge it from the storage bin, and carry it into a carry-out section, thereby simplifying the facility.
[0024]
Preferably, the grain dry storage facility according to the present invention is covered with a building having a heat insulating wall, in which the first grain storage bin group and the second grain storage bin group are arranged in parallel. Further, an air exhaust passage for air sent below each bin when discharging temporarily stored and long-term stored grain is attached to a part of the building, and the exhaust passage is connected to another grain storage bin. It is made to receive suction by the exhaust fan. Thereby, it is not necessary to install a new exhaust fan and dust removal device for the second grain storage bin, and the exhaust fan and dust removal device used in the first grain storage bin can be used in common. There are merits such as.
With the above configuration, the grain dry storage facility according to the present invention can be particularly suitably used as a grain dry storage facility constituting a country elevator.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail by the description of the embodiments with reference to the drawings. 1 is a schematic flow diagram of a grain dry storage facility according to the present invention, FIG. 2 is a schematic top view showing the main part of the grain dry storage facility of FIG. 1, and FIG. 3 is a grain dry storage of FIG. It is a schematic front view of a facility.
Although not shown in FIG. 1, the grain drying storage facility includes a load receiving hopper 1, a load lifting elevator 2, a coarse sorting machine 4, a weighing machine 5, and the like on the carry-in side, as shown in FIG. 4. A grain carry-in section is provided, and on the carry-out side, a grain carry-out section including an adjustment tank 6, a selective weighing equipment 7, a hulling adjustment plant 8, a shipping tank 9, and the like is provided (see FIG. 2).
[0026]
In the grain drying storage facility, as shown in the figure, bins consisting of A1 to A12, B1 to B12, C1 to C12, and D1 to D12 are arranged close to each other in four rows as bins for drying or storing grains. As will be described later, the three series of the A column, the B column, and the C column constitute the “first grain storage bin group” in the present invention, and the D series represents the “second grain storage bin group”. Is configured. Note that the number of columns and the number of bins in each column are set as appropriate according to the planned receiving amount.
[0027]
Each of the storage bins of the A row, the B row, and the C row constituting the first grain storage bin group is 50 tons bins in this example, and is sized to accommodate a maximum of about 56 tons of grains in the natural input state. . On the other hand, each storage bin in the D row constituting the second grain storage bin group is 100 tons in this example, and as shown in FIG. 3, the plane area is almost the same as 50 tons, but the height is It is almost doubled.
[0028]
Further, in each of the storage bins of the A row, the B row, and the C row constituting the first grain storage bin group, each of the 1 to 10 storage bins stirs the grains in the tank at least in the vertical direction. A stirrer 100 is attached. The stirring device is arbitrary as long as it can substantially uniformly stir the grains in the storage bin in the vertical direction. However, an already known stirring device already proposed by the present applicant (Japanese Patent Laid-Open No. 7-103646). (See Japanese Patent Publication No. 7-155050, etc.).
[0029]
As shown in FIG. 2 and FIG. 3, in this grain dry storage facility, in the grain storage bin group, on the right side (hereinafter referred to as the front side for convenience), the grain carry-in section, the carry-out section, and the selection of straw are selected. Each member constituting the weighing equipment is disposed, and the air conditioner 20 and the blower 21 described above are disposed in the vicinity of the left side (hereinafter referred to as the rear side for convenience). Further, a bin input elevator E is arranged in front of each of the grain storage bin rows A to D, and further, a bin input is placed above the grain storage bins of the A row, the B row, and the C row. A conveyor 11 and a bin input moving conveyor 11A with a dispersing device are arranged, respectively, and a 100-ton bin input conveyor 11B is arranged in the D row. A discharge conveyor 12 is provided below the grain storage bins in rows A to D, and the front end (feed downstream end) is located near the grain input port of the bin input elevator E (also in FIG. 1). See) In this example, there are a total of 2 discharge conveyors 12 shared by both rows between the A row and B row, and one discharge conveyor 12 shared by both rows between the C row and D row. A book discharge conveyor 12 is provided.
[0030]
Further, the lower part of each of the bins A to D forms an air supply path (drying air blowing duct) P, and the supply paths P in the A, B, and C rows are connected to the air conditioner 20. It is connected to the provided blower 21 and is supplied with dehumidified air and is used to dry the grains in each bottle. The supply path P below the storage bins in the D row constituting the second grain storage bin group is connected only to the blower 21 so that air of an amount necessary for discharging stored grain can be supplied. . In FIG. 2, the grain supply path to the bin input elevator E for supplying the grains to the storage bins of the C row and the D row is omitted, but the grains are supplied in the same manner from the grain carry-in section described above. .
[0031]
In the above-mentioned grain dry storage facility, the grains received on the first day are weighed by the weighing machine 4 every predetermined amount (for example, 300 kg), and then passed from the bin input elevator E through the bin input conveyor 11 to the bin input movable conveyor 11A. And distributed evenly for each of the columns A to C. At that time, for example, three drying bottles (1 to 3) having a stirring device 100 set to process one day in each series are equally distributed. All of these operations are performed fully automatically depending on the state of the received grain (for example, moisture content, variety, quality, etc.).
[0032]
Grain received on the second day is the number of bottles (4-6) with the other one-third stirring device 100 free, and the remaining 3 minutes on the third day is free The same number of bottles (7 to 9) having one stirring device 100 is put in the same manner. The cereal that has been put in is gently dried without moisture unevenness by the uniform stirring by the stirring device 100 and the dehumidified air from the blower 21 provided with the air conditioning device 20. When the daily amount of receiving is larger than the planned amount, the 10th bin also receives the receiving grain. The fourth day is a day of receiving goods, and only drying is performed in each bin (1-9). At this stage, of course, the damper is operated so as not to send wind to the bin not containing the grain.
[0033]
On the 5th day, the grains put in on the 1st day (contained in the bottles 1 to 3) are uniformly dried to a semi-dry moisture state, The bin input elevator E, the 100-ton bin input conveyor 11B, and the like are operated to feed into the grain storage bins D1 to D12 constituting the second grain storage bin group. Grains loaded on the 5th day are thrown evenly into the bins (1-3) emptied by discharging the grains to the second grain storage bin group by the same operation again. Thereafter, by repeating this operation every day, the second grain storage bin group D1 to D12 becomes full after the required number of days have elapsed. After that, the semi-dry cereals that are in a semi-dry moisture state are filled with the bins (the 11th and 12th bins in each row) of the first grain storage bin group that do not have the stirring device. Evenly.
[0034]
In this state, the dry storage bins (1 to 10) having the stirring device become empty. Therefore, the bins are repeatedly charged equally on the first day, the second day, and the third day, and cumulative mixing stirring drying is performed while the stirring device 100 is operated. As described above, the cumulative mixing and agitation drying is performed on the fourth day as a drying day on the receipt of goods. By doing in this way, the whole quantity can be received with respect to the designed grain receiving quantity, and it can dry slowly and uniformly evenly to a semi-dry state. Further, in the cumulative mixing stirring drying, drying may be performed in the same bottle until a specified finish drying.
[0035]
Next, finish drying of the semi-dry moisture state grain is performed. In the finish drying, the first grain storage bin group (the 11th and 12th bins) having no stirring device is added to the bin (the 10th bin each) having an empty stirring device in the first grain storage bin group. The semi-dry grains stored in the second grain storage bin group (D1 to D12) are sequentially transferred. Depending on the cargo receiving conditions, there may be a case where cumulative mixing stirring drying is proceeding even in each tenth bottle equipped with the stirring device. In that case, the dry grains in one of the 1st to 10th bottles with a stirrer, which has been processed up to the final drying by continuing the cumulative mixed stirring drying, are divided into other bins with a stirrer. Then, temporarily store and secure a single empty bottle with a stirring device. Then, using the emptied bottle, the semi-dried grains are sequentially transferred and finish-dried in the same manner as described above. After finish drying, the dried cereal is returned to its original bottle. By repeating this operation, the semi-dried stored grains are finished and dried in a short time and stored.
[0036]
In the grain dry storage facility according to the present invention, there is no particular limitation on the arrangement of the grain storage bin groups and the arrangement of the air supply means such as the grain carry-in section, the carry-out section, and the blower, but as shown in FIG. If the grain carrying-in part and the carrying-out part are arranged on one side in the longitudinal direction and the air supply means is arranged on the other side, there is an advantage that the whole grain drying storage facility can be made compact.
[0037]
In addition, in the illustrated example, the second grain storage bin group (D1 to D12), which is 100 tons bins, is arranged in parallel with the first grain storage bin group and outside the parallel arrangement. It may be located in the center. In that case, there is an advantage that the heat insulating material covering the periphery can be reduced. Furthermore, as described above, in the second grain storage bin group, it is sufficient that the air can secure an air volume capable of discharging the grains in one bin for discharging grains. Therefore, in the illustrated example, an air conditioner is used. Although not attached, only the blower 21 dedicated to discharge is attached, but although not particularly illustrated, from the air supply path connected to the blower provided with an air conditioner for sending dehumidified air to the bottles of the A to C rows, It may be branched before the bin and connected to the air supply path of the second grain storage bin group, and a damper is attached to distribute the necessary air volume only when discharging from the second grain storage bin group.
[0038]
Preferably, as shown in FIGS. 2 and 3, the grain drying storage facility is entirely covered with a building having a heat insulating wall, and the exhaust fan 40 of the first grain storage bin group is attached to the side wall. The exhaust fan 40 is connected to a dust removing device 41. Then, the dehumidified air supplied to the first grain storage bin group passes through the exhaust fan 40 and the dust remover 41 and is discharged to the atmosphere. More preferably, a part of the building is designed as a ventilation air exhaust passage 50 used for discharging the grains in the second grain storage bin group, and the exhaust passage 50 is used as the first grain. Suction is performed by the exhaust fan 40 of the storage bin group. By doing in this way, it becomes unnecessary to provide a separate wind exhaust fan and dust removal equipment for the second grain storage bin, and the cost of the grain drying storage facility as a whole can be reduced.
[0039]
In addition, the provision of a grain storage bin (second grain storage bin group) that is more than twice the capacity of the dry bin (first grain storage bin group) makes it possible to reduce the number of storage bins. In addition, the reduction of the flat area, the number of input transfer machines, and the number of discharge transfer machines can be reduced to the minimum, and the cost merit by reducing the number of machines is also great. In addition, it is a complicated circuit because the 4 series of discharge conveyors are shared by 2 bins and a total of 2 discharges are used as conveyors, and grain can be input and discharged simultaneously in 1 series of bins. Full automation can be realized without the need for monitoring, and monitoring can be greatly simplified, and operation with the minimum number of personnel is possible where there is a shortage of personnel.
[0040]
【The invention's effect】
According to the grain drying storage facility according to the present invention, it is not necessary to secure a larger number of rotation bottles than the facility that requires rotation without a conventional stirring device, and more than the facility where the stirring devices are installed in all the bottles. The number is small and the number of stirring devices can be reduced. Also, as the large-capacity grain storage bin (second grain storage bin), the same area as that of the small-capacity grain storage bin (first grain storage bin) is used, thereby reducing the installation area of the entire facility. As a matter of course, by reducing the number of bins, it is possible to reduce the number of transfer machines for inputting and discharging grains. Further, the entire amount of dehumidified air can be involved in drying, and a low-cost facility can be provided.
