Description

[Detailed description of the invention] This invention relates to a storage device mainly for storing polished rice in ordinary households.The purpose is to maintain the inside of the grain storage container at a low temperature with an extremely inexpensive structure. Our objective is to provide a grain storage device that is possible.

In general, the quality of rice is greatly affected by the proper storage, so it is stored in cool warehouses, and at rice stores, it is stored in commercial storage that blows cold air into the warehouse to maintain the quality of rice. It is sold to general consumers.

However, in recent years, ordinary households find it troublesome to frequently buy polished rice, which is a staple food, so they store about 18 times the amount of polished rice in the household in measuring rice bins, but these measuring rice bins are made of bent metal plates. It is a simple container, and is usually placed in the kitchen, where the room temperature is the highest in the house.In the late spring, the inside of the rice bin becomes hot and humid at around 20 degrees Celsius, causing the polished rice to change quality and deteriorate. Insects and rice worms occur,
The quality of rice deteriorates significantly.

In particular, polished rice that is stored in rice bins is much more susceptible to deterioration than brown rice, and in recent years, large quantities of soft rice from Tohoku, which is extremely high quality but easily deteriorated, has been distributed around the Kinki region. The reality is that we are eating bad-tasting rice made from spoiled rice, and since this is a staple food that we Japanese people eat once or twice, there is a risk that we may suffer from loss of appetite due to the bad taste.

This invention was devised in view of the above-mentioned problems, and aims to provide a grain storage device that solves the above-mentioned problems by having a structure that can be manufactured at low cost and can maintain the inside of the container at a low temperature.

Hereinafter, embodiments of this invention will be explained in detail based on the drawings.

Reference numeral 1 indicates an outer container, and 2 indicates a grain storage container.As shown in FIGS. 2 and 3, the peripheral side wall of the unstorage chamber of the outer container 1 has a square cross section and a length of one side is small. Three different cylindrical bodies3. 4. 5 are loosely inserted into each other with a certain gap, and the opening peripheral portions of their respective upper and lower ends are fitted and fixed into respective annular grooves formed in the ring-shaped support frame 6 and the support plate 7, respectively. In addition, each cylindrical body 3~
By evacuating and sealing the annular gap 5, the heat insulating annular spaces 8 and 9 are formed into a double structure.

The grain storage container 2 is loosely fitted into the unstored chamber of the outer container 1 with a certain gap, and the lower surface of the hopper part 2a of the storage container 2 is mounted on an eccentric support plate 7. It is supported by a plurality of supporting metal fittings 11 fixed upright to the water collection board 10, and the outlet port 2b of the hopper part 2a is connected to the water collection board 1.
0 and a connecting pipe 12 inserted through the support plate 7 to a well-known weighing mechanism 13, and from the weighing mechanism 13 to a wood outlet 14, a weighing board similar to the conventional one as shown in FIG. By pushing down any measuring side 16 of the storage container 2, the amount of polished rice stored in the storage container 2 is taken out from the outlet 14 in accordance with the operated measuring side 16.

Reference numeral 17 indicates an equipment storage chamber formed below the rice storage chamber in the outer container, and this storage chamber is equipped with a cooling device 18 similar to that installed in an electric refrigerator or the like.

That is, a compressor 191, a condenser 20, and an evaporator cooling pipe 21 are provided, and the cooling pipe 21 is wound spirally between the innermost cylindrical body 5 of the rice storage chamber and the storage container 2. In addition, a temperature sensing device 22 such as a thermostat is provided protruding from the storage container 2, and a control panel 23 controls the driving of the cooling device 18 based on the temperature detected by the temperature sensing device 22.
is installed inside the equipment storage room 17.

In the figure, 24 is a drain pipe that communicates with the reservoir of the water collection board 10 and is attached to the support plate 7, 25 is an evaporation plate, 26 is a support leg, and 27 is a viewing window through which the rice in the storage container 2 can be seen. , 28 denotes a lid for closing the outer container 1 and, by extension, the storage container 2.

In the embodiment device configured as described above, when polished rice is placed in the storage container 2 and the cooling device 18 is powered and driven, the refrigerant radiates heat and liquefies in the condenser 20 and absorbs heat in the cooling pipe 21. The cold air is evaporated and the storage container 2 is cooled from the outside, and this cold air is conducted to the polished rice inside the storage container 2. When the polished rice is cooled by convection and reaches a predetermined temperature, the temperature is measured by the temperature sensing device 22. When detected, the operation of the control panel 23 stops the driving of the cooling device 18, and this control operation maintains the polished rice at an appropriate temperature of 13°C to 18°C.

Here, since the circumferential side wall of the outer container 1 is formed with a double annular space 8.9 and the periphery of the storage container 2 is double vacuum insulated, this storage device can be placed easily. Even in modern kitchens, infrared rays and hot air from the kitchen are almost completely blocked by foamed polystyrene boards, carbonized cork boards, etc. that are filled in the surrounding walls of ice cream containers, electric refrigerators, etc.
Compared to insulating materials such as asbestos or glass wool, it is inexpensive yet exhibits an extremely excellent cold retention effect, consumes less power, and cools the storage container 2 from the outside, so that the moisture in the polished rice is reduced. The rice is not lost and water droplets do not adhere to the inside of the storage container 2, and the temperature and humidity can always be maintained at an appropriate temperature regardless of the season, and polished rice can be maintained and stored in good quality for a long period of time.

The water droplets adhering to the cooling pipe 21 run down the gap between the cylindrical body 5 and the storage container 2, and drip from the reservoir part of the water collection board 10 via the drain pipe 24 onto the evaporation dish 25.

Incidentally, although the above embodiment describes an example in which the invention is applied to a rice bin, this invention is not limited to the above embodiment, and can also be applied to, for example, storage of barley, wheat, soybeans, adzuki beans, etc. Of course, the vacuum cross-sectional space is limited to two, but may be one or three, and furthermore,
The size of the shape is arbitrary, but if the volume is increased, it can be used as a storage area for farmers to store one year's worth of brown rice at home, and in such cases it is especially effective since it can be stored for a long time. is remarkable.

As explained above, according to the grain storage device of this invention, the grain storage container is cooled from the outside, and the storage container is rationally built into an outer container having a circumferential wall provided with a vacuum insulation space. Because of this structure, it is possible to efficiently cool and keep the container for storing grains cold with an extremely inexpensive structure, and especially when applied to a rice bin, it is extremely remarkable that rice food equivalent to new rice can be enjoyed for a long period of time. obtain practical effects.
