Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain drying storage facility for drying and storing grain using a plurality of grain storage bins.

[0002]

2. Description of the Related Art Conventionally, various grain drying and storage facilities have been proposed in which grains from individual producers are collected, dried and stored, and after processing such as hulling, necessary adjustments are made and shipped. . The grain drying and storage facility is called an A-type country elevator, a B-type country elevator, a C-type country elevator, or the like. The facilities have been constructed mainly for thermal drying, although the receiving system and the drying system are different. In recent years, facilities that apply a dehumidifier to drying of grains instead of thermal power have been developed, and have been accepted and accepted by consumers for good taste and safety.

For example, Japanese Patent Application Laid-Open No. Hei 3-122484 has a large number of storage bins and a processing device such as a huller. The drying bin is supplied with dehumidified air dehumidified by an air conditioner and is carried into the drying bin. Dehumidifying and drying cereals, storing the dried cereals in storage bins, taking out the cereals stored in storage bins as necessary, processing them such as hulling, and packing them before shipping. Has been proposed.

[0004] This drying treatment equipment is to solve the disadvantages of the conventional thermal drying, but there may be a difference in moisture between the upper layer and the lower layer of the stored grain during drying, and especially in large drying facilities. In addition, since the drying bin has a capacity of about 50 tons per bin, and the pile height of the grain may be 5 m or more, uneven drying tends to occur. Therefore, usually, a replacement bottle is provided separately from the drying bottle, and when one dehumidification drying step in the drying bottle is completed, the grains are replaced from one of the drying bottles into the replacement bottle, and the empty drying bottle is dried. Transfer the grain of another drying bottle to the bottle, replace the dry bottle with the empty one at the end and transfer the grain of the bottle, so-called rotation work, mix the well dried grain of the lower layer with the slow drying grain of the upper layer, Then, the moisture is made uniform by performing dehumidification and drying again. This operation is repeated a plurality of times so that the dehumidifying and drying of the grains in each drying bin does not cause uneven drying.

However, in such a dry storage facility,
In addition to a large number of drying bottles, a large number of storage bins and replacement bins are required, which not only increases facility costs, but also
In large facilities with many drying bottles, this rotation is a heavy workload. The rotation capacity depends on the wind discharge capacity, but the discharge capacity in a normal dry storage facility is 20 to 30 tons per hour,
It takes 2-3 hours to empty one 0 ton bin.
For example, in the case of a facility having several lines of 10 or more bins per line, this rotation operation alone may result in one day being required.

As a solution to the inconvenience, a grain drying and storage facility that does not require a rotation operation as shown in FIG. 4 has been proposed (for example, Japanese Patent Laid-Open No. 7-103).
648). In the figure, 1 is a receiving hopper for collecting grain, 2 is a receiving elevating machine, 4 is a roughing machine, 5 is a weighing machine, and the received grain is weighed by a predetermined amount and then bin-in from the bin-in elevator E. Conveyor 11
Via a predetermined bin (rows A1 to A7 and rows B1 to B7)
Are sequentially supplied with the same thickness. The lower part of each bin row forms a supply path (dry air blowing duct) P for dehumidified air, and the supply path P is connected to the air conditioner 20 and the blower 21 to supply dehumidified air. Used to dry the grain in each bottle. In addition, 13 is a grain input port with an on-off valve. A discharge conveyor 12 is provided below the bin rows A1 to A7 and B1 to B7, and the processed grain is fed from the discharge conveyor 12 to a control tank 6, a selective weighing facility 7, a hulling adjustment plant 8, a shipping tank 9, and the like. Is provided. In this processing facility, each bin (A1-
A7 and B1 to B7) are characterized in that a stirrer 100 that can stir the grain to be accommodated at least in the vertical direction is attached. In the figure, 14 is a grain take-out port with an on-off valve.

[0007] In this grain drying and storage facility, the grains in each storage bin are constantly stirred at least in the vertical direction by the agitator 100, so that dehumidification can be performed without performing a so-called rotation operation as in a conventional grain drying and storage facility. The desired drying process can be completed without causing uneven drying of the grains in the bottle in the drying process by the supply of air. In addition, the grains after the drying process can be stored in the bottles as they are, and the idle bottles can be eliminated, resulting in a reduction in facility and maintenance costs as a whole. Further, it is possible to prevent a loss of air volume due to rotation, and it is possible to cause the entire amount of dehumidified air to participate in drying.

[0008]

As described above, in the case of a facility that requires a rotation operation, there is a disadvantage that the rotation takes too much time, and a replacement bin (rotation bin) is secured separately from the drying bin. Is essential, for example, in a 3000 ton processing facility, 50 ton bins had to be installed in excess of 70 bins. In addition, if loading and rotation can be performed at the same time, it is necessary to increase the number of weighing machines because weighing will be duplicated. And there is also a disadvantage that the working time is long.

Further, in the case of a dry storage facility in which a stirrer is attached to all the above-mentioned bins, although the number of bins is smaller than that of a rotation system, recently, for example, 3000 tons of grain has become larger. Taking the processing facility as an example, if the variety of varieties is multi-variable, the quantity of one varieties is not always in the unit of 50 tons, so the required number of grain storage bins may exceed 60 bins, and If a stirrer is installed in all the bottles, the initial cost including the control panel tends to rise. In addition, three motors are usually provided with one stirring device, and the running cost when the power is concentrated at one time and all the units are operated can not be despised. In addition, since the number of driving parts is large, there is also mechanical wear, and the maintenance and inspection of the operator is inevitably performed with a large amount of work.

It is an object of the present invention to provide a novel grain dry storage facility which has solved the above-mentioned disadvantages of the conventional dry storage facility. More specifically, the present invention provides a grain storage bin ( For example, 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 a stirrer) and reducing maintenance work. It is in.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, a grain drying and storage facility according to the present invention basically comprises a grain loading section and a plurality of grain storages for drying and / or storing grain. Bins, air supply means for feeding air to the grain storage bin, and a grain drying storage facility including an unloading unit for unloading the processed grain, the number of grain storage bins, at least the grain to be accommodated A first grain storage bin group provided with a stirrer capable of stirring in the vertical direction, and a temporary storage of semi-dried grains dried to semi-dry moisture in the first grain storage bin group and a storage of dried grains. And a second grain storage bin group to be used, wherein each grain storage bin constituting the second grain storage bin group is larger than each grain storage bin constituting the first grain storage bin group. It is noted that To.

For example, in the case of rice, the harvested rice received is
As the initial drying, the moisture is usually dried from 24% to 17%, and the primary storage is performed. Thereafter, the semi-dried cereal stored in the primary is finally dried to a specified moisture of 16 to 14.5% or less, and selected as required. (Measured by the Ministry of Agriculture, Forestry and Fisheries)
17%, the Ministry of Agriculture, Forestry and Fisheries uses 1 draft without ventilation as a standard for safe short-term primary storage.
7% or less and storage within 35 days). Therefore, when "semi-dry moisture" is used in this specification,
In the above meaning, it refers to a moisture content of about 17%. In the case of "semi-dried grain", it refers to a grain in which the moisture content is about 17% in the above sense, and in the case of "finish drying", it refers to the above. Grain which became about 17% in meaning is defined moisture 16-1
It means to be dried to 4.5% or less, and when "dry grain" is used, the defined moisture content is 16 to 1 in the above sense.
A grain that has been finished and dried to 4.5% or less.

In a dry grain storage facility according to the present invention, when grain is brought into the facility from a grain producer, the grain is:
Grains are sequentially fed from the grain carry-in section to a grain storage bin provided with a stirrer constituting a first grain storage bin group. 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 different from that of a conventional grain dry storage facility. Similarly, the grains undergo drying. In the present invention, each grain storage bin is provided with a stirrer that can stir the stored grain at least in the vertical direction, and by the action of the stirrer, the grain in the grain storage bin is dried in the course of drying. Is equally stirred up and down over the entire area.
Therefore, as in a conventional grain drying and storage facility, the grains stored in the storage bins are stored without having to exchange grains (rotation work) between storage bins or between a drying tank and a replacement tank. It is of equal moisture dried in equal proportions in the bottle, and no drying unevenness occurs in dehumidification and drying of grains in the same storage bottle.

[0014] In a preferred embodiment, the air supply means includes an air conditioner provided with a dehumidifier and a blower, and at least the grain storage bin provided with the agitator is supplied with dehumidified air from the air supply means. It can be sent. For this reason, the cereal carried in is uniformly dried to a semi-dry moisture state. In a preferred aspect, the first cereal storage bin group further includes a cereal storage bin without a stirring device. In addition to the function of storing semi-dried cereals in the primary storage and storage of dried cereals described below, it can also be used for drying when the amount of high moisture cereals received per day exceeds the designed amount. That's why.

Hereinafter, as an example of facility design, for example,
The grain drying and storage facility according to the present invention will be described in detail by taking as an example a case where processing is performed in a four-day cycle of three-day receiving and one-day suspension. In this case, the grains received on the first day are evenly spread over one third of the total number of dry storage bins having the stirring device. The grain received on day 2 has another one-third free bin, and the grain received on day three has the remaining one-third bin free.
Each is stuck in the same way. The stuffed grain is gradually dried without unevenness of water by uniform stirring by a stirring device and dehumidifying air. The fourth day is a non-loading day, and each bottle is only dried.

On the fifth day, the grains fed on the first day are uniformly dried to a semi-dry moisture state, and the semi-dried grains are stored in the grain storage bins constituting the second grain storage bin group. Sent to The grains received on the fifth day are evenly put again into the bins emptied by discharging the grains to the second grain storage bin group by the same operation. Thereafter, this operation is repeated every day. After the required number of days, the second cereal storage bins are full. Thereafter, if the first cereal storage bin group is provided with a bottle having no stirring device, the semi-dried cereal in the semi-dry moisture state is also uniformly charged into the bin until it becomes full.

In the grain drying and storage facility according to the present invention, each of the grain storage bins constituting the second grain storage bin group has a larger capacity (preferably, each of the grain storage bins constituting the first grain storage bin group). Is twice or more), so that the number of grain storage bins constituting the second grain storage bin group can be reduced, and both the first grain storage bin and the second grain storage bin have a 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 plane area of the bin group row is reduced. There are merits such as reduction.

After that, charging is uniformly repeated on the first, second, and third days into the dry storage bottle having the above-mentioned stirring device. As described above, the cumulative mixing stirring drying is also a drying day on the fourth day. Through this repetition, the facility can receive the entire amount of the designed grain receiving amount, and can uniformly and slowly dry the water to a semi-dry state. In addition, the above-mentioned cumulative mixing stirring drying started from the late stage of receiving and drying,
Since it is possible to dry in the same bottle up to the specified finish drying, it is desirable to continue the cumulative mixing stirring drying and proceed to the finish drying in consideration of the simplicity of operation and the energy consumption.

Next, the grain which has been brought into a semi-dry moisture state as described above is subjected to finish drying. In the finish drying, a bin provided with an empty stirring device for the first grain storage bin group is prepared from the beginning, and the first grain storage bin group having at least a stirring device in the bin and the second grain storage bin group are provided. Semi-dry cereals stored in the cereal storage bin group are sequentially transferred and performed. According to another method, the capacity of each grain storage bin constituting the first grain storage bin group is set to be somewhat larger from the beginning (for example, in the case of a 50 ton bin, a size that can be accumulated to about 56 tons by natural input). ) The dried grain in one of the plurality of bottles with a stirrer, which has been made and then subjected to the final drying by continuing the cumulative mixing and stirring drying, is divided into other bottles with a stirrer. To secure a single empty bottle with a stirrer, and place the first empty bottle in the empty bottle.
Of the cereal storage bin groups, the bins having no stirring device and the semi-dried cereal stored in the second cereal storage bin group are sequentially transferred to finish drying. After finishing drying,
The dried cereal is returned to its original bottle. By repeating this action, the semi-dried stored grain is finished dry and stored in a short period of time.

As described above, in the case of the grain drying and storage facility according to the present invention, the finishing drying is performed by cumulative mixing and agitation drying, so that there is almost no operation of the facility and only monitoring is the main task, and personnel can be saved. In addition, the bin having the agitating device in the first grain storage bin group can be used for both the drying bin and the storage bin, and the operation efficiency of the entire 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.

The drying and finishing drying of the high moisture content cereal to a semi-dry moisture is performed in a bin having a stirring device in the first cereal 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 which does not include the stirring device and the second grain storage bin group which includes the grain storage bins, only the primary storage of semi-dry grains and the storage of dry grains are performed. Yes, sending dehumidified air is not necessary. Therefore, it is only necessary that the bottles can be supplied with air having an air volume necessary for discharging the stored grains, and energy saving of the entire facility can be achieved.

In the present invention, when the first grain storage bin group is provided with a grain storage bin without a stirrer, as described above, the amount of high moisture grain received per day exceeds the design amount. When brought in, it can be used for drying, and has the advantage that the grain loading section, air supply path, grain loading section, etc. can be shared. In the grain storage bins connected to the air supply path and having the stirrer and the grain storage bin not having the stirrer, the shutter is closed after the drying process is completed or when necessary. The connection with the supply channel is cut off, and as described above, it can be used as it is as a grain storage bin as in a normal dehumidifying and drying facility.

Preferably, each of the grain storage bins constituting the first and second grain storage bin groups is arranged in a multi-row shape, and one side of the row group in the longitudinal direction is a loading section for the grain. And a discharge section, the air supply means is disposed on the other side, and a bin input conveyor is disposed above the row group, and a discharge conveyor is disposed below the row group. This makes it possible to carry in the necessary grains, put them in the storage bins, discharge them from the storage bins, and carry them in to the unloading section, thereby simplifying the facility.

Preferably, the grain drying and storage facility according to the present invention is covered with a building having an insulating wall, wherein the first grain storage bin group and the second grain storage bin group are arranged in parallel. Further, an exhaust path for air sent below each bin when discharging the temporarily stored and long-term stored grains is attached to a part of the building. The grain storage bin is sucked 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 commonly used. There are advantages such as. With the above configuration, the grain drying and storage facility according to the present invention can be particularly suitably used as a grain drying and storing facility constituting a country elevator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail by describing embodiments with reference to the drawings. FIG. 1 is a schematic flow diagram showing a grain dry storage facility according to the present invention, FIG. 2 is a schematic top view showing a main part of the grain dry storage facility of FIG. 1, and FIG. 3 is a grain dry storage facility of FIG. It is a schematic front view of a facility. This grain drying and storage facility has
Although not shown in FIG. 4, as shown in FIG.
On the carry-in side, there is provided a grain carry-in section composed of a grain receiving hopper 1, a grain lift / lift 2, a roughing machine 4, a weighing machine 5, and the like. A grain discharge unit including a hulling adjustment plant 8, a shipping tank 9, and the like is provided (see FIG. 2).

The cereal drying and storage facility is a bin for drying or storing cereals.
12, B1 to B12, C1 to C12, and D1 to D12
Are arranged in four rows in close proximity to each other, and as will be described later, three rows of row A, row B, and row C constitute the “first grain storage bin group” in the present invention. , D series constitute a “second grain storage bin group”. In addition, the number of rows and the number of bins in each row are appropriately set according to the expected receiving capacity.

Row A, which constitutes the first grain storage bin group,
Each of the storage bins in the rows B and C is a 50-ton bin in this example, and has a size capable of accommodating a maximum of about 56 tons of grains in a natural input state. On the other hand, each storage bin in row D constituting the second grain storage bin group is 100 ton bin in this example, and as shown in FIG. 3, the plane area is almost the same as 50 ton bin, but the height is It is almost doubled.

Further, in each of the storage bins in row A, row B, and row C, which constitute the first grain storage bin group, 1 to 1
A stirrer 100 for stirring the grains in the tank at least in the vertical direction is attached to the zero storage bin. This stirring device is optional as long as it can substantially uniformly stir the grains in the storage bin in the vertical direction. However, a known stirring device already proposed by the present applicant (Japanese Patent Laid-Open No. 7-103646). Japanese Patent Laid-Open Publication No. Hei 7-155050) is particularly effective.

As shown in FIG. 2 and FIG. 3, in the grain drying and storage facility, the grain loading section described above is located near the right side (hereinafter referred to as the front side for convenience) in the drawing of the grain storage bin group.
The components that constitute the unloading unit and the selective weighing and measuring equipment for paddy are arranged, and the air conditioner 20 and the blower 21 described above are arranged near the left side (hereinafter referred to as the rear side for convenience). In addition, bin input elevators E are arranged in front of the grain storage bin rows A to D, respectively, and bin input elevators are located above the grain storage bins in row A, row B and row C. A conveyor 11 and a bin-injecting moving conveyor 11A with a dispersing device are respectively arranged, and 100 rows are arranged in row D.
A tombin feeding conveyor 11B is provided. Each A ~
A discharge conveyor 12 is located below the grain storage bins in row D.
The front end (feed downstream end) is located near the grain input port of the bin input elevator E (see also FIG. 1). In this example, a single discharge conveyor 12 shared by both rows in the middle of row A and row B, and a single discharge conveyor 12 shared by both rows in the middle of row C and row D. A book discharge conveyor 12 is provided.

Further, the lower part of each of the A to D bin rows forms an air supply path (drying air blowing duct) P,
The supply passages P in the rows A, B, and C are connected to a blower 21 having an air conditioner 20, and dehumidified air is supplied to dry the grains in each bin. The supply path P below the storage bins in row D constituting the second grain storage bin group is a blower 21
And it is possible to supply air with the air volume necessary for discharging the stored grain. In FIG. 2, the grain supply path to the bin input elevator E that inputs the grains into the storage bins in the row C and the row D is omitted, but the grain is supplied in the same manner from the grain loading unit described above. .

In the above-mentioned grain dry storage facility, the grain received on the first day is weighed by the weighing machine 4 for each predetermined amount (for example, 300 kg), and then the bin input elevator E
Is transferred to the bin loading moving conveyor 11A via the bin loading conveyor 11, and is equally distributed for each of the rows A to C.
At that time, for example, three drying bottles (1 to 3) each having a stirrer 100 set to process one day in each series.
3) Evenly distributed. All of these actions are performed automatically based on the condition of the received grain (eg, moisture content, variety, quality, etc.).

On the second day, the cereal received is the number of bins (4 to 4) having another one-third of the stirring device 100 that is free.
6) On the third day, the cereal received is the number of bottles (7-9) with the remaining one-third stirring device 100
, Respectively. The stuck grain is evenly stirred by the stirrer 100 and the air conditioner 2
Due to the dehumidified air from the blower 21 provided with “0”, the air is gradually dried without moisture unevenness. When the daily receiving volume exceeds the expected volume, the 10th bin also holds the receiving grain. The fourth day is a non-loading day, and only drying is performed in each bin (1 to 9). At this stage, of course, the damper is operated so that wind is not sent to the bottles containing no grain.

On the fifth day, the cereal (the ones contained in bottles 1 to 3) charged on the first day is uniformly dried to a semi-dry moisture state, and the semi-dried cereal is discharged to the associated discharge. By operating the conveyor 12, the bin input elevator E, the 100-ton bin input conveyor 11B, and the like, the conveyers are fed into the grain storage bins D1 to D12 constituting the second grain storage bin group. The grains received on the fifth day are evenly put into the bins (1 to 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 groups D1 to D12 become full after the required number of days have elapsed. After that, the first
The semi-dry cereal in the semi-dry moisture state is evenly filled into the bins without a stirrer (the 11th and 12th bins in each row) of the cereal storage bin group of the above. .

In this state, the dry storage bins (1 to 10) having the stirring device are empty. Therefore, the bottles are repeatedly charged evenly on the first day, the second day, and the third day,
Therefore, while the stirring device 100 is being operated, cumulative mixing, stirring and drying are performed. As described above, the cumulative mixing stirring drying is also the drying day on the fourth day on the non-loading day. By doing so, the entire amount of the designed grain receipt amount will be received,
Moisture can be uniformly and slowly dried to a semi-dry state. In addition, in the cumulative mixing stirring drying, drying may be performed in the same bottle until a specified finish drying.

Next, finish drying of the grains in a semi-dry moisture state is performed. Finish drying is performed in the first grain storage bin group with empty stirrers in bins (10th bin each), the first grain storage bin group without stirrer (11th and 12th bins) and Second grain storage bin group (D1 to D1)
The semi-dried cereal stored in 2) is transferred sequentially.
Depending on the receiving conditions, it may happen that the cumulative mixing, stirring, and drying are proceeding in each of the tenth bottles provided with the stirring device. In such a case, the dried grain in one of the first to tenth bottles with a stirrer that has been subjected to finish drying by continuing the cumulative mixing and stirring drying is divided into other bottles with a stirrer. To temporarily store and secure one empty bottle with a stirrer. Then, utilizing the empty bottle, semi-dry 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 gesture,
In a short period of time, the semi-dried stored grain is finished dry and stored.

In the dry grain storage facility according to the present invention,
Although there is no particular limitation on the arrangement of the grain storage bin group and the arrangement of the air supply means such as the grain loading / unloading section and the blower, FIG.
As shown in the figure, when the grain loading and unloading section and the like are arranged on one side in the longitudinal direction of the grain storage bin group and the air supply means is arranged on the other side, the whole grain drying and storage facility can be made compact. There is an advantage that can be achieved.

In the illustrated example, the second grain storage bin group (D1 to D12), which is a 100 ton bin, is positioned in parallel with the first grain storage bin group and outside the parallel arrangement. However, of course, it may be located at the center. In that case, there is an advantage that the heat insulating material covering the periphery can be reduced. Further, as described above, in the second grain storage bin group, it is sufficient for the air to be able to discharge the grain in one bin for discharging the grain, so that the air conditioner is used in the illustrated example. Not attached,
Although only a blower 21 dedicated to discharge is provided, although not shown in particular, from the air supply path connected to a blower provided with an air conditioner for sending dehumidified air to the bins A to C in front of the bin. The branch may be branched and connected to the air supply path of the second grain storage bin group, and a damper may be attached to distribute the required air volume only when discharging from the second grain storage bin group.

Preferably, as shown in FIGS. 2 and 3, the grain drying and storage facility is entirely covered with a building having heat insulating walls, and the exhaust fan 40 of the first grain storage bin group is provided on the side wall. Is attached, and the exhaust fan 40 is provided with a dust removing device 41.
Is connected to The dehumidified air supplied to the first grain storage bin group is supplied to the exhaust fan 40 and the dust removal device 4.
1 to be discharged to the atmosphere. More preferably, a portion of the building is provided with a blast air vent 50 used to discharge grains in the second grain storage bins.
And the exhaust passage 50 is sucked by the exhaust fan 40 of the first grain storage bin group.
By doing so, there is no need to provide a separate exhaust fan and dust removal equipment for the second grain storage bin,
Cost reduction of the whole grain drying and storage facility can be achieved.

Drying bottles (first cereal storage bin group)
By providing the grain storage bins (the second grain storage bin group) having a capacity of twice or more of the above, the number of storage bins can be reduced, and the flat area can be reduced, the number of input transfer machines, The number of discharge transfer machines can be reduced to the minimum, and the cost merit due to the reduction in the number of machines is great. In addition, since the four discharge conveyors are shared by two bins, a total of two discharge conveyors are used as conveyors, and the grain input and discharge can be performed simultaneously in a single bin, so a complicated circuit is required. The system can be fully automated without the need for monitoring, supervising is extremely simplified, and in places where there is a shortage of personnel, it is possible to operate with a minimum number of personnel.

[0040]

According to the grain drying and storage facility of the present invention, it is not necessary to secure a larger number of rotation bins than a conventional facility that requires rotation without a stirrer, and a stirrer is provided for all bins. Fewer bottles and fewer stirrers than the installation facility. As a large grain storage bin (second grain storage bin),
The use of a small-capacity grain storage bin (the first grain storage bin) with the same flat area reduces the installation area of the entire facility, as well as reducing the number of bins, thereby allowing for the input and output of grain. Transport machines can be reduced. Further, the entire amount of dehumidified air can be involved in drying, and a low-cost facility can be provided.
