Description

Grain storage bin

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to grain storage for relatively long-term storage without degrading the quality of grains such as rice and barley, and more particularly to low-temperature and compact grain storage, which is optimal for home use.

In general, when grains such as brown rice are stored at a temperature of 20 ° C. or higher, for example, their taste is lowered, and in extreme cases, weevil is produced in addition to the generation of condensation and mold. Due to the phenomenon, the quality may be deteriorated. For this reason, farms or agricultural cooperatives provide long-term storage by using a granary for storing brown rice or rice at a low temperature around 10 ° C, for example. What it is doing is the current state.

On the other hand, today, even in ordinary homes, the habit of purchasing brown rice and performing rice taste according to individual taste and cooking rice immediately after rice taste tends to increase. However, even a small rice mill is almost 10-20 kg, and most of the rice milling units are mostly in the state of white rice after rice milling, and in addition, I have to keep it in the state of normal temperature; There is a possibility that the taste of the polished rice after polishing may decrease.

Therefore, it is conceivable to store the polished white rice at low temperature by using a refrigerator. However, for example, even a large-sized home refrigerator is not designed to store white rice, even though it is a large one. many. For example, even a small amount of polished rice is stored in a bag and stored, but it is very troublesome to take it out every time it is cooked.

On the other hand, since the conventional grain storage is inherently intended for business use, the storage capacity is large, requires a large amount of energy, and provides a large number of separate cooling units and a large occupancy area. In addition, in order to maintain a low temperature state, it is necessary to thermally block the storage unit from outside air by a heat insulator, but most of the grain outlets or outlets for taking out grains are not provided with a heat insulator. There is a problem that the power loss is large. It is also conceivable to enclose the entire reservoir including the outlet of the grains with a heat insulator, but it is not preferable because the volume of the space requiring cooling becomes large and requires more energy.

In addition, the Peltier element is installed in a part of the outer shell constituting the storage unit and quenched by a cooling fan. However, for local quenching, not only the storage unit may cause condensation, but also the temperature in the entire storage unit There is a problem that the distribution becomes uneven and the cooling rate is slow.

An object of the present invention is to solve the problems existing in the prior art, and to provide a grain storage which maintains the quality of grains, is small and has low power consumption, and can uniformly store grains at low temperatures.

In order to solve the said subject, Claim 1 of this invention WHEREIN: The storage for grain storage provided in the space formed so that the heat insulating material may be arrange | positioned and enclosed in the grain storage which has a storage part for grain storage inside. Section, a compressor and a condenser provided outside the space, an evaporator provided between the side of the storage section and the heat insulating material, and a fan disposed above the storage section for storing grains, between the compressor, the evaporator, and the condenser. It is characterized in that the refrigerant is configured to circulate to cool the storage unit, and to form air in the storage unit to flow.

BRIEF DESCRIPTION OF THE DRAWINGS It is a principal part longitudinal cross-sectional view which shows embodiment of this invention. In FIG. 1, 1 is a box-shaped outline and is formed in the shape of a rectangular parallelepiped of 35 cm in width, 50 cm in inner length, and 40 cm in height, using a heat insulating material as a structural member (for example, white rice capacity 15 kg). On the support 2. 3 is a lid member, and makes a heat insulating material a structural member, and is attachably attached to the opening part above box-shaped outline 1. In addition, by providing a rubber magnet, for example, on the contact surface with the box-shaped outer body 1 of the lid member 3, the adhesiveness of both can be improved.

Next, 4 is a storage part, it is provided in the inside of the box-shaped outer body 1, and it is formed so that the white rice 5 can be thrown in and stored, for example in the upper opening part. The lower part of the storage part 4 is formed in the shape of a funnel, The discharge part 6 which penetrates the box-shaped outer body 1 is provided in the lower end part. 7 is a fan and is provided in the upper part of the storage part 4. Further, 8 and 9 are small windows made of a transparent material, and are provided on the side of the storage unit 4 and the box-shaped outer shell 1, respectively, and the remaining amount of the white rice 5 in the storage unit 4 is determined. It is to confirm from the outside.

10 is a shutter and is installed to be movable in the horizontal direction facing the discharge port 6. In addition, the shutter 10 is formed using the heat insulating material as a structural member at least in the vicinity of the discharge port 6. 11 is a metering part, and it is provided so that the shutter 10 may penetrate in the vicinity of the tip part of the shutter 10, and the shape of the projection shape to the plane is formed corresponding to the discharge port 6. As shown in FIG. 12 is a stopper, is provided below the box-shaped outer body 1, and is for regulating the moving range of the shutter 10. As shown in FIG. 13 is an extraction part, is formed in a box shape, and is installed below the shutter 10 so as to be movable in a horizontal direction, and the guide 14 is applied to the white rice from the metering part 11 of the shutter 10. Can be stored through.

15 and 16 are respectively a compressor and a condenser, and are installed in the support 2. 17 is an evaporator, and is installed between the side of the storage part 4 and the side of the box-shaped outline 1, for example, so as to surround the storage part 4. And the compressor 15, the evaporator 17, and the condenser 16 are connected through piping, and a refrigerant | coolant is comprised so that circulation is possible.

According to the above configuration, when the lid member 3 is opened, a predetermined amount of white rice 5 is introduced into the storage portion 4 from the upper opening portion, and the lid member 3 is attached to the box-shaped outer body 1. As for the storage part 4, the circumference | surroundings are surrounded by the heat insulating material, and it will be in the state which the entry | exit of heat to the outside was interrupted | blocked. Moreover, since the shutter 10 which consists of a heat insulating material as a structural member is provided in the discharge port 6 of the lower part of the storage part 4, heat shielding is also completed in the vicinity of this discharge port 6 also.

Next, since the refrigerant is adiabaticly expanded in the evaporator 17 by the operation of the compressor 15, the air between the storage unit 4 and the box-shaped outer enclosure 1 is cooled, and the storage unit 4 is cooled by the air. The white rice 5 in) may be indirectly cooled and kept at a low temperature of 9 to 15 ° C., for example, and stored without degrading the quality. Moreover, since the air in the storage part 4 flows through the fan 7, the temperature difference between the wall of the storage part 4 and the internal air can be made small.

As described above, the white rice 5 and the air in the storage unit 4 are indirectly cooled through the wall of the storage unit 4, and the air in the storage unit 4 flows, so that the storage unit 4 It is effective to prevent condensation.

Next, when taking out the white rice 5 in the storage part 4, if the shutter 10 is first moved to the right side and the stopper 12 is contacted, the metering part 11 will face the surface just below the discharge port 6. Therefore, the white rice 5 falls in the measurement part 11 by predetermined amount (for example, about 150 g or about 1 hop). When the shutter 10 is moved to the left side, the discharge port 6 is closed by the shutter 10, and the white rice accommodated in the metering unit 11 is also moved, so that the tip of the shutter 10 is moved to the guide 14. When it reaches, the white rice in the metering part 11 falls into the extraction part 13 through the guide 14, and a predetermined amount of white rice can be taken out by moving to the right side of the extraction part 13 ,. When a large amount of acquisition is required, the above operation is repeated.

In the case where it is not necessary to weigh when taking out the white rice, a through hole may be provided at a position facing the discharge port 6 of the guide member 18 of the shutter 10.

In addition, since long-term use may cause mold or the like to adhere to the inner surface of the storage unit 4, the shutter 10 and the extraction unit 13, it is preferable to periodically clean the shutter 10. Since it is usually configured to not pull out of the warehouse, the shutter 10, the discharge port 6, the guide 14 and the like cannot be cleaned. For this reason, it is preferable that the stopper 12 which regulates the movement range of the shutter 10 is formed so that it may be easily separated out of a warehouse by screwing etc., for example, and it is comprised so that the shutter 10 may be taken out of a warehouse. Moreover, if the front part of the support body 2 is also formed detachably, the said cleaning operation will become easy.

In the embodiment of the invention described above, an example in which the storage portion is formed in a substantially rectangular parallelepiped shape has been described. However, the present invention is not limited to this, but may be cylindrical, and the lid member is attached to the box-shaped outer body through a hinge. It is okay. In addition, the outlet may be positioned not only in the center of the reservoir but also in the front, rear, left, and right directions. In addition, the grain storage of this invention can target grains other than rice, and the capacity and dimensions can also be set to arbitrary things as needed.

The present invention has the following effects because it has the same structure and effect as described above.

(1) Since the inside of the storage can be cooled indirectly, condensation at the time of quenching can be prevented and grains can be prevented.

(2) By the flow of air in the storage, the temperature difference between the wall surface temperature of the storage and the internal air can be reduced, and condensation in the storage can be prevented.

(3) Since the outer surface of the storage is cooled as a whole, the temperature distribution is uniform and the cooling rate is high.

(4) By setting it as the structure which improves the heat insulation effect of an exhaust port vicinity, power loss can reduce and power consumption can be reduced.
