    Grain insect storage method and grain storage container
    Various methods and devices for long-term preservation of grains such as brown rice have been proposed. The packaging method for long-term storage of rice grains disclosed in Japanese Patent Application Laid-Open No. 48-26516 includes placing grain in the bag, replacing the air in the bag with carbon dioxide, and leaving the carbon dioxide in the bag with a specific gravity of 0.8 to 0.9 in the bag. Means for drying the rice grains until the water content of the rice grains and the water content of the carbon dioxide gas is balanced to a low moisture content have been proposed. However, since this storage means considers the moisture content of rice grains and does not consider any insecticidal action of cereals (grainworms) contained in grains, carbon dioxide gas is blown through the bag and the carbon dioxide gas concentration decreases. It can cause the occurrence of a grainworm.
    In addition, Japanese Laid-Open Patent Publication No. 49-116246 discloses storage of cereals in an inert gas atmosphere, and proposes long-term preservation by filling cereals in a silo (SILO) of an inert gas atmosphere and automatically adjusting the pressure, temperature and humidity in the storage tank. Doing. However, in the present invention, a silo having a rigid structure is required, and furthermore, since the silo needs to be manufactured to be sealed, it is impossible to transport and requires a large, completely sealed facility, and the manufacturing cost is high.
    Japanese Patent Application Laid-Open No. 1-279812 discloses a pesticidal method for storage brown rice pests. In this invention, it is disclosed that pests of brown rice pests are brought into an atmosphere having a vaporized carbon dioxide concentration of 50% or more. However, this insecticide is based on a large silo having a rigid structure, and the carbon dioxide gas charged therein is extremely high, and a means of reducing the amount of carbon gas used is also disclosed.
    Disclosure of the Invention
    In view of the above fact, the present invention does not require a large, rigid structural equipment, and is convenient for transport, and has an effective insecticidal and deficiency effect with a minimum amount of carbon dioxide, and is suitable for long-term stockpiling. The purpose is to get.
    According to the first aspect of the present invention, a bag of flexible material is stored in a high-strength bag, and the grain is filled in the bag, and then the bag is filled with carbon dioxide and closed to store the grain in a pesticidal state. . In this case, the envelope may be maintained at a carbon dioxide gas concentration of 40% or more for 7 days or may be made of a heat-adhesive plastic having a carbon dioxide gas permeation rate of 6300 cc / m 2 or less at 24hr.1 atm.
    The second aspect of the present invention has an inner bag made of a flexible material and closed after being filled with carbon dioxide and filled with grains, and a high-strength bag containing the bag. In this case, the bag may be made of a flexible material capable of maintaining a concentration of at least 40% of the filled carbon dioxide for at least 7 days, and a bag having a high strength to accommodate the bag. May be made of heat-adhesive plastic having a carbon dioxide gas permeation rate of 6300 cc / m 2 · 24hr · 1 atm or less, and a hanging member of a hanging ruler provided on the envelope.
    According to the present invention, it is possible to maintain an air-blocking atmosphere during grain storage so as to be free of oxygen, so that grains and other grains such as brown rice, rice, and wheat can be preserved in a state free of pests for a long time, and lifted and transported Since it can be installed, it has the effect of improving the transportation effect.
    According to the present invention, when storing grains, CO 2 concentration can be maintained for 40 days for 7 days, and the air-blocking atmosphere can be maintained to have a pesticidal effect such as a cereal insect by the absence of oxygen, thereby enabling long-term grain preservation.
    In the present invention, in the case of filling the inner bag with the inner bag, the inner bag may be accommodated in the outer bag after the grain is filled in addition to the case where the inner bag is filled with the grain. The inner bag is sealed after the filling of the grain to keep it airtight, but this sealing can be applied with various sealing means such as adhesive and clamping clamp in addition to heat fusion by heat seal. And to also meets the inclusion CO 2 permeability of less than one equivalent to the other part to the sealed part.

    1A to 2 illustrate an inner bag 10 which is an inner body for grain storage. 3 to 7 show that the inner bag 10 is accommodated in the outer bag 12 which is an outer body and the brown rice 14 is filled in the inner bag 10.
    As shown in FIGS. 1A and 1B, the inner bag 10 is integrally formed and stored in a folded state. As shown in Fig. 2, in the state where the inner bag 10 is expanded and expanded, a cylindrical portion (diameter extension) 10A is formed in the center portion, and a small cylindrical portion 10B as an inlet coaxially above and below the cylindrical portion. The small cylindrical portion 10c serving as the discharge port is connected to each other via the shaft-diameter portion 10D.
    The inner bag 10 is made of a flexible material such as an inflation film, and these materials have a CO 2 permeation rate of 6300 cc / m 2 · 24hr · 1atm or less and an internally charged CO 2 concentration of at least 40% over 7 days. It is to be maintained. As a result, insects, larvae, adults, and chrysalis of pests, particularly grains, attached to the grains filled therein, can be given an environment in which oxygen is killed.
    As an example, the inner bag 10 has a filling amount of brown rice of 1 ton (volume 1,200 to 1,300 liters) and a dimension x width x height dimension of 900 x 900 x 1300 mm or more.
    The outer bag 12 shown in FIGS. 3 to 5 is made of a material of high strength, which is formed into a rectangular box shape by sewing a synthetic fiber (for example, a flat woven fabric using a flat yarn made of PP) by sewing them. It is desirable to have the property of withstanding the damage caused by the projections from the protrusions, the tensile force in case of hanging down, the tip force, and the compressive force in the case of lamination in multiple layers. The inner volume (particularly the horizontal cross-sectional area and height) of the outer bag 12 is slightly smaller than the volume (particularly the horizontal cross-sectional area and height) of the inner bag cylindrical portion 10A, whereby the brown rice is filled into the inner bag 10. In the inner bag 10, the lateral load is supported by the inner wall of the outer bag 12.
    As shown in Figs. 4A and 4B, the cylindrical portion 22 communicates with the cylindrical portion 22 through an opening formed in the center portion of the top portion 12A. The tubular portion 22 has a lower outer periphery hermetically bonded to the lower surface of the top portion 12A and is sealed to the top portion 12A as necessary. On the outer periphery of the intermediate part of the cylindrical part 22, the bundle string 26 is hold | maintained by the hanging piece 28. Therefore, when the tie string 26 is turned to the outer circumference of the tubular portion 22 and pulled at both ends, the tie strings 12B and the tubular portion 22 can be bundled and tightened tightly.
    The tip ends of the plurality of tongue pieces 12B integrally formed at the opening edges of the top portion 12A are folded and sealed upside down, and the middle portions of the bundle strings 24 are inserted through the flipped portions. Therefore, the tie string 24 is also tied to the tubular portion 22 like the tie string 26 to pull both ends and then connected to each other can be tightly tied to the top opening. In this case, the tubular portion 22 already closed by the tie string 26 is pressed into the outer bag 12 through the top opening, so that the tubular portion 22 does not protrude upward from the top portion. In addition, a circular cover plate 12C made of the same material as that of the outer bag 12 is mounted on a part of the outer circumference of the standing piece 12B, so that the cylindrical portion 22 pushed into the outer bag from the top opening. After covering the cover plate 12C through the plurality of standing pieces 12B, the cover plate 12C is placed inside the top opening that is tightly fastened by the tie string 24 by tying the tie string 24. It is disposed and shields the inner bag 10 from the outside.
    In addition, the bottom part of the outer bag 12 is also provided with a standing piece 12B, a tubular part 22, a bundle string 24, 26, and the like as the top part 12A, so that the upper and lower parts of the outer bag 12 are the same. It is structured.
    In addition, both ends of the suspension stand 32, which is a hanging member, are enclosed in a suitable place on the outside of the outer bag 12, and a system such as a hook installed on a crane means such as a hoist or a crane by using the suspension stand 32 is used. It is designed to be lifted up to earth and transported and installed. As the hanging member, an opening may be formed in a part of the outer bag 12 in addition to the hanging stand 32 to form a hanging part such as a hook.
    Next, the method of storing brown rice by this inner bag 10 and outer bag 12 is demonstrated.
    The inner bag 10 performs a heat seal 36 on the small tubular portion 10C as shown in FIG. 1B to close the lower end portion. This heat seal heats the small cylindrical part 10C by a hot plate, an inpulse seal, etc., and closes the small cylindrical part 10B by heat fusion of a material.
    Thereafter, the inner bag 10 is inserted through the top cylindrical part 22 of the outer bag 12 closed with the tie strings 24 and 26 in advance and filled with air therein, as shown in FIG. The inner bag 10 expands in the outer bag 12. The small cylindrical portion 10C and the shaft diameter portion 10D after the heat seal are stretched flat to adhere to the bottom surface of the outer bag 12 in a planar manner. In this state, brown rice is filled in the inside of the inner bag 10 through the small cylindrical part 10B as shown to FIG. 4A and FIG. 4B.
    Here, as shown in FIG. 5, a rigid guide tube 38 having an outer diameter of about 10 mm made of metal such as iron, copper, synthetic resin, etc. is inserted into the brown rice 14 through the small cylindrical portion 10B. The rigid guide tube 38 preferably inserts the lower end 38A into the vicinity of the bottom of the inner bag 10 so that CO 2 can easily exclude the internal air. In order to prevent the brown rice 14 from entering the lower end portion 38A, a porous closure member such as a mesh may be provided. The rigid guide tube 38 communicates with the CO 2 vessel 46 via a flowmeter 42 and a vaporizer 44. The liquefied carbon dioxide in the CO 2 vessel 46 becomes gaseous carbon dioxide via the vaporizer 44 and is filled into the inner bag 10. Since carbon dioxide has a greater specific gravity than air, carbon dioxide is filled between the microscopic particles in the inner bag 10 while excluding the air remaining in the inner bag 10 from the small cylindrical portion 10B. By arranging the CO 2 sensor 48 in the small cylindrical portion 10B of the inner bag 10, it is possible to detect a state in which the carbon dioxide is filled in the inner bag 10. The CO 2 supplied into the inner bag 10 may not necessarily be 100% concentration.
    Therefore, in the case where the increased CO 2 is detected by the CO 2 sensor 48 into the inner bag 10 and the elevated CO 2 is detected, the CO 2 supply is stopped from the rigid guide tube 38 and the rigid guide tube 38 is removed from the brown rice 14. At the same time, the small cylindrical portion 10B of the inner bag 10 is closed with the heat seal 52 as shown in FIG. 6. As an example, when the weight of brown rice in the inner bag is 150Kg, the CO 2 supply from the rigid guide tube 38 can be filled with CO 2 in 7 minutes if it is 15 l / min. Thereafter, the small tubular portion 10B is pushed into the outer bag 12 through the tubular part 22, and the outer bag 12 closes the tubular part 22 with the bundle strap 26 and at the same time the barrel. Storing of the brown rice 14 is completed by pressing the mold part 22 also into the outer bag 12, covering 12C of cover plates, and tying the bundle string 24 again. The outer bag 12 in which the brown rice storage is completed can be stacked and stored at an appropriate position in the warehouse using the suspension stand 32.
    In addition, the discharge of the brown rice 14 maintains the suspension stand 32 to lift the outer bag 12 together with the inner bag 10 and release the bundles 26 and 24 of the bottom of the outer bag 12 to form a tubular portion ( When opening 22) and cutting the small cylindrical portion 10C of the inner bag 10 at the portion biased to the rectangular cylindrical portion 10A rather than the heat seal portion, the brown rice 14 automatically cuts the small cylindrical portion 10C and the like. It is discharged through the tubular portion 22 at the bottom of the bag 12.
    In this way, the CO 2 permeation rate of the inner bag 10 is 6300 cc / m 2 · 24hr · 1 atm or less, and when the filling amount of the brown rice 14 is 1 ton or less, the amount of carbon dioxide that can be filled between the brown rice particles is about 750 liters. It can maintain a carbon dioxide gas concentration atmosphere of more than 40% inside for 7 days. Therefore, it is possible to maintain conditions under which oxygen-depleted pests, such as grainworms, that enter the brown rice 14 die in an oxygen-deficient state, and to be preserved for a long time thereafter.
    Table 1 shows the embodiment and the comparative example using the stored results in turret having a CO 2 permeability of the various. In Example 1, a linear low-density polyethylene (LLDPE) film was used as an inner bag, and an outer bag was used as a flat woven fabric of 15 yarns per inch each of a flat yarn made of polypropylene (PP) having a thickness of 1500 deniers (D). . The outer bags of Examples 2 and 3 and Comparative Example 2 are the same as those of Example 1, and the inner bags of Example 2 have a five-layer structure in which the intermediate layer is ethylene / polyvinyl alcohol (EVOH) having a thickness of 10 μm, and the thickness of both sides is 5 It was produced by co-extrusion inflation molding in which a linear low density polyethylene (LLDPE) having a thickness of 30 μm was disposed via an adhesive of AD (mu). The inner bag of Example 3 has a three-layer structure in which the intermediate layer is an aluminum (AL) film having a thickness of 10 μm, one side having a polyester (E) having a thickness of 25 μm, and the other having a low density polyethylene (LD) having a thickness of 50 μm. Laminated film. Their envelopes were 450 x 450 x 750 mm in length x width x height dimensions, and the inner bag was 480 x 480 x 800 mm.In Examples and Comparative Examples, 110 kg of California rice was filled and carbon dioxide was filled at a rate of 15 liters per minute for 7 minutes. After opening, the opening was heat sealed. In addition, the CO 2 permeation amount is based on the gas permeability test method of JIS and K7126.
    Examples 1 to 3 all satisfy the conditions of maintaining a carbon dioxide concentration of 40% for 7 days, and all the cereals (adults, larvae, pupa and four ecology of eggs) in the inner bag during carbon dioxide filling are killed. Later on, no more than 60 days of incidence was observed. In Comparative Example 1, since there was no inner bag and the outer bag had no carbon dioxide gas shielding effect, it did not kill the worm (4 ecology) and caused a large amount. Comparative Example 3 could not be completely killed because the carbon dioxide gas shielding effect was insufficient. In Examples 2 and 3, the carbonic acid gas concentration was maintained at 40% for 60 days, during which no mold and the like were reproduced, and antibacterial and anti-fog effects were maintained. As shown in Fig. 7, the carbon dioxide gas permeation rate of more than 6300cc / m 2 · 24hr · 1atm, the carbonic acid gas concentration is more than 40%, can not maintain the environment for 7 days, so the carbonic acid gas permeation amount of 6300cc / m 2 · 24hr · By using the film of less than 1atm to preserve brown rice, it is possible to long-term storage of brown rice in the insecticidal state.
    In addition, in the present invention, the material of the inner bag 10 may be a polyvinyl chloride (PVDC) and a polyethylene layer in addition to the above, and may have an alumina deposition film on the outside thereof integrally with the above, or else the material having the above carbon dioxide transmission amount. Any material can be applied.
    Alternatively, as in Example 1, a plurality of inner bags may be stacked, or as in Example 2, a plurality of multilayer bags may be stacked as an inner bag, or a plurality of single layers and multiple layers may be stacked as an inner bag. In these cases, some of these may be partially heat-sealed or the like.
    As described above, the present invention is useful in the industry of storing, transporting or selling grains while preserving the grains in a dead state of pests over a long period of time to improve the transportation efficiency.
