Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry storage building which guarantees the quality of grains and reduces the construction cost of a treatment facility.

[0002]

2. Description of the Related Art Harvested rice will be described below as an example of grain. The harvested rice processing facility must ensure the quality of the rice during the harvested rice treatment process, that is, the storage, drying and hulling process of the harvested rice. The quality of rice refers to mold, taste, cracking of the harvested rice at the time of storage, skin deviation of brown rice at the time of hulling, and the like. And there is a lot of water in the rice, and
If it is stored for a long period of time, mold will be generated, and if it is overly dried, so-called overdrying will cause deterioration of taste and cracking of the body. Therefore, the water content of rice greatly affects the quality of rice. Also, since rice itself is a living thing, if the temperature is high, the respiration of rice becomes active and the energy inside the rice is consumed (hereinafter referred to as the deterioration of grains), and the quality of rice deteriorates. Since the reproductive activity of rice plants becomes active and causes mold development, which reduces the quality of rice, the temperature of the stored rice itself also has a great influence on the quality of rice. In this way, the quality of rice is affected by the moisture content and temperature of the rice, so the building itself for protecting the storage tank that stores the rice from outside air conditions and maintaining the prescribed moisture and temperature Consideration should be given from the viewpoint of water content and temperature.

On the other hand, in the current trend of international liberalization of agricultural products, in order to cultivate international competitiveness, both quality and price of rice must be satisfied.
Regarding the price reduction, one of the major factors is to reduce the construction cost of the harvested rice processing facility and lower the unit price of the harvested rice processing facility per farm.
For this reason, it is currently instructed to reduce the construction cost of harvested rice processing facilities.

As a conventional dry storage building, a plurality of storage bins 1 and a machine room 2 are provided as shown in FIG. 4, a bin loading elevator 6 is provided in the machine room 2, and a blower 3 as other main equipment. Although not shown, the dehumidifier 4 was provided with a receiving hopper for receiving harvested grains, a huller, and the like. Then, the harvested rice received by the receiving hopper is transferred to the upper part of the bin 1 by the bin elevating machine 6, and is dispersed and stored in each bin 1 by the dispersing machine 7. Further, in Japanese Patent Laid-Open No. 3-127909, a storage bin for dryly storing harvested rice is constructed with a standardized panel, and this storage bin is used as a part of the wall of the building and at the same time as that of the building. The other walls were constructed using the same panels that were used to construct the storage bins, and a roof with a normal roof structure was installed on top of them to reduce the construction cost of the harvested rice processing facility. A storage building is disclosed.

[0005]

However, the above conventional building has the following problems to be improved. That is, in the conventional building shown in FIG. 4, since the bin loading / lowering device 6 is installed in the machine room 2, the ceiling height of the machine room 2 is made equal to the ceiling height of the storage bin 1. In addition, if the ceiling height of the machine room 2 is made equal to that of the storage bin 1 in this way, the machine room 2 also has to have a steel structure because of the strength of the building, and the construction cost is high. There is a problem of becoming. Further, since the conventional roof structure of the building used a normal structure, the so-called attic space of the building is heated by the radiant heat of the roof heated by solar heat, and the temperature inside the building is raised. There is a problem that the raised temperature in the building affects the quality of the grain stored in the storage tank.

The temperature and humidity inside the building for dry storage are adjusted to the appropriate temperature and humidity in order to maintain the quality of the stored grain. If the temperature of the building changes, it becomes difficult to control this air, and the thermodynamic relationship between the temperature of the outside air and the temperature inside the building may cause condensation on the inner surface of the roof. Difficult to adjust.

When it becomes difficult to control the temperature and humidity in the building as described above, it becomes difficult to control the temperature and the moisture content of the grain stored in the storage tank, and the grain deteriorates in the high temperature portion, or There is a problem that microorganisms may propagate and mold may be generated to deteriorate the quality of grains.

It is also possible to form a heat insulating layer or a heat insulating space in the attic in order to eliminate the above effect of the radiant heat of the roof, but the construction cost of the treatment facility becomes high and the unit price of facility use per farm is high. There is a problem of becoming.

The present invention has been made in view of the above problems, and simplifies the structure of the machine room and the roof to reduce the construction cost of the machine room and the roof itself, and
It is intended to provide a building for dry storage of grains that can maintain the high quality of grains without being affected by the radiant heat of the roof.

[0010]

[Means for Solving the Problems] A first means according to the present invention for solving the above problems is to construct a plurality of dry storage bins by a panel, and use a part of the plurality of dry storage bins as a machine. It is characterized in that at least a bin loading elevator is provided in the machine room, and the second means is to construct a double tent structure roof directly on the storage bin of the first means. It is a feature.

[0011]

Since the present invention is constructed in this way, it has the following actions. That is, since a plurality of dry storage bins are constructed by a panel, a part of the plurality of dry storage bins is used as a machine room, and at least the bin loading elevator is arranged in the machine room, the ceiling height of the machine room is reduced. It is possible to construct a machine room with a structure that is lower and independent of the storage bin. Also, if the roof of the building is constructed with a double structure tent, it is possible to form an air layer in the double structure space and have a heat insulating effect, and reduce the effect of radiant heat due to solar heat. At the same time, it becomes possible to reduce the roof construction cost by simplifying the roof structure itself.

EXAMPLE An example of the present invention will be described below. First, in FIG. 1 showing a plan view, the arrangement of the most common equipment as a grain dry storage facility will be described. In the embodiment shown here, four square storage bins 1 are provided. One of the 1 is used as the machine room 2,
A bin loading elevator 6 is arranged in the machine room 2. Further, in this embodiment, the blower 3 and the dehumidifier 4 are arranged in the machine room 2. 201 is an auger hopper 5 and a huller 50
An auxiliary equipment room for accommodating auxiliary equipment such as 1st class. The storage bin 1 and the machine room 2 are constructed by a standardized panel P having the same size. The panel P is made of, for example, a porous material having a heat insulating effect.

The harvested rice that has been harvested and received by the auger hopper 5 is transferred upward by a bin loading elevator 6 as shown in FIG. 2 and delivered to a bin receiving conveyor 7 disposed above the bin 1. . Next, the harvested rice transferred by the bin receiving conveyor 7 is rotated and dispersed by the rotary dispersing device 8.
While being dispersed by the above, it is put into the bin 1 at a substantially uniform layer height and is distributed and stored in the three bins 1. On the other hand, the air whose temperature and humidity have been adjusted by the dehumidifier 4 is supplied by the blower 2 to the air passage 12 provided at the bottom of the bottle 1.
The harvested rice is supplied from the bottom of the bin 1 through which the harvested rice is stored, and the temperature and humidity of the harvested rice stored in the bin 1 are adjusted. Then, the harvested rice stored in the storage bin 1 is paid out by the bottom conveyor 10.

In FIG. 3, the bottle 1 and the machine room 2 are provided with a roof 13, and the roof 13 has a double structure of a flyer tent 131 and an inner tent 132. An air chamber 133 is formed. In this embodiment, the roof 13 having the double structure of the flyer tent 131 and the inner tent 132 is exemplified, but it is sufficient if the tent itself has heat insulating property, and the roof 13 having the double structure of the flyer tent 131 and the inner tent 132 is limited. Not something. Further, inside the building, the boundary between the bin 1 and the machine room 2 is partitioned by a tent so that the heat of various machines generated in the machine room 2 does not affect the space environment on the bin 1 side.

The operation of the present embodiment thus constructed will be described below. First, the operation will be described from the viewpoint of construction cost. In the present embodiment, one of the four storage bins 1 is used as the machine room 2, and the tall bin loading lifting device 6 is arranged in this machine room 2, so that the auxiliary equipment room 201 is in an independent state. Thus, it becomes possible to make a simple auxiliary equipment room such as a tent with a low ceiling height. Therefore, it is not necessary to make the auxiliary equipment room 201 (corresponding to the conventional machine room) a steel frame structure, so that the roof 13 can be built directly on the storage bin 1 and the machine room 2, and Since it is not necessary to roof the auxiliary equipment room 201, the construction area of the roof 13 can be reduced accordingly.

Further, since the storage bin 1 is constructed with the same standardized panel P and one of the storage bins 1 is used as the machine room 2, the construction material cost, the delivery date and the design and construction work are simplified. Can be converted. In addition, the roof 13 is constructed with a flyer tent 131 and an inner tent 132, so no special heat insulation structure is adopted.
As a result, the internal atmospheric conditions of the entire building can be prevented from being affected by the external air conditions, and the structure of the roof 13 can be simplified. Moreover, since the weight of the roof 13 is reduced by constructing the roof 13 with the flyer tent 131 and the inner tent 132, it is possible to simplify the foundation work of the entire facility. In this case as well, if a tent having a high heat insulating property is used as well, it is not necessary to form the roof 13 having a double structure, and the above operation is the same. Further, when the auxiliary equipment room 2 is constructed with a simple tent, the construction cost is further reduced.

Next, the operation will be described from the viewpoint of the quality of the stored harvested rice.
Air chamber with double structure of 31 and inner tent 132 1
Since the air chamber 133 is formed, the air chamber 133 serves as a heat insulating layer, and it becomes possible to block the temperature atmosphere in the attic 14 from the outside air temperature.

Since the solar heat is cut off by the heat insulating effect of the air chamber 133, the temperature rise of the inner tent 132 is suppressed, whereby the radiant heat radiated to the space of the attic 14 can be reduced. Further, the further reduction of the radiant heat can be achieved by blackening the color of the flyer tent 131 to absorb the radiant heat or to select a color which reflects the radiant heat. Even if the outside air temperature becomes low in winter, the heat insulation effect of the air chamber 133 makes the temperature gradient between the inside of the air chamber 133 and the attic 14 at the boundary of the inner tent 132 gentle, so that It becomes possible to prevent dew condensation on the inner surface.

In this way, the temperature of the air in the attic 14 should not be affected by the outside air conditions by the roof 13, and one of the storage bins 1 should be used as the machine room 2 to reduce the volume of the attic 14. Therefore, the temperature and humidity in the building can be maintained and the temperature and humidity of the harvested rice stored in the storage bin 1 can be easily adjusted, and the inner tent 13
Since it is possible to prevent the occurrence of dew condensation on No. 2, it is possible to maintain the high quality of the harvested rice stored in the storage bottle 1. The above explanation was given for the roof 13 with the double structure of the flyer tent 131 and the inner tent 132.
In short, if a tent having a high heat insulating property is used, it is not necessary to make the roof 13 having a double structure, and the above operation is the same.

[0020]

As described in detail above, according to the present invention, since one of the plurality of storage bins is used in the machine room and at least the bin loading / lowering device is arranged in this machine room, it is directly mounted on the storage bin. The roof can be constructed, and the construction area of the roof can be reduced to significantly reduce the construction cost. Since the roof of the building was constructed with a double-structured tent, an air layer is formed in the double-structured space to provide a heat insulating effect, reducing the effect of radiant heat from solar heat and It is possible to maintain high quality, simplify the roof structure itself without installing a special heat insulation layer structure, and reduce the construction cost of the grain processing facility. Further, by using a tent having a high heat insulating property, the same effect can be obtained without duplicating the roof structure. Moreover, by constructing the auxiliary equipment room with a simple tent, the construction cost can be further reduced. As a result, it is possible to maintain the high quality of grains and significantly reduce the unit price of facility use per farmhouse.
