Description

Grain cellar

The present invention relates to a grain reservoir, and more particularly, to properly stir grains by appropriately rotating a screw operated by a motor inside a reservoir capable of storing grains such as rice or soybeans. The present invention relates to a grain reservoir capable of maintaining freshness by arranging a heat exchanger through which a cool refrigerant passes and maintaining a constant temperature inside the reservoir.

Since agricultural products such as fruits and vegetables or livestock products such as milk and meat are easily deteriorated at room temperature, they can be kept fresh for a long time only by using a cold storage or a cold storage that is kept below a certain temperature. To this end, large refrigerated warehouses are installed in agricultural production complexes and direct sales farms. In particular, in the case of exporting the agricultural products overseas by using a vessel, the container is used. Only when the inside of the container is kept at a low temperature, the agricultural products can be kept fresh for a long time and receive a proper value.

As such, there are various introductions to storage, refrigerated warehouses, and cold stores for foods that are fresh, such as fruits and meats. However, there are no refrigerators for grains for safely storing grains such as rice, beans, and corn. not.

However, in the case of rice, even if the moisture is slightly changed, the rice worms are produced, and in severe cases, the quality of the rice is significantly degraded and the taste of rice is deteriorated by the rice crumbs. In particular, when insects are produced in the rice for sale, there is a problem in that it cannot receive a full price by adversely affecting the quality. In addition to rice, grains such as beans, corn and red beans can also be stored for long periods of time without deterioration only if they are maintained at the appropriate temperature and humidity.

In order to solve this problem, the present invention is equipped with a stirring screw in a reservoir that can store grains such as rice or soybeans, while stirring the grain evenly, while maintaining the temperature of the storage compartment containing grains appropriately The aim is to provide a grain storage which can be kept fresh for a long time by preventing alteration.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the grain storage in accordance with a preferred embodiment of the present invention.

1 is a front view showing a grain reservoir according to the present invention, Figure 2 is a cross-sectional view showing the interior of the grain reservoir according to the present invention, Figure 3 is a plan view showing the configuration of the upper plate employed in the present invention.

As shown in Fig. 1, the preferred embodiment of the present invention illustrates a structure suitable for use in a general home. As such, although FIG. 1 illustrates a grain storage similar to a general household rice container, it is also possible to manufacture grain storage in various other forms. The cover 32 is covered with an upper portion of the out case 10 constituting the outer shape of the grain storage, and a control operation unit 60 is provided on the front surface. In addition, the button 24 and the take-out box 20 having a structure similar to that used in a general household rice container is installed at the bottom. A handle 22 is attached to the front of the take-out box 20.

Next, Figure 2 is a cross-sectional view of the grain reservoir according to the present invention, the inside is shown empty without grain. The overall structure of this is that the outer case 10 which forms the outer wall of the lower plate 12 and the grain storage, and the circumferential surface is attached to the outer case 10 in the inclined downward direction, and discharges grain. A guide plate 14 having a discharge port 14a formed therein, an upper plate 34 and a cover 32 disposed above the storage chamber 18 provided by the guide plate 14, and a lower portion of the storage chamber 18. A compressor 42 and a condenser 46 installed in the provided machine room 16, a heat exchanger 48 surrounding the storage compartment 18 to supply cold air while the refrigerant sent from the condenser 46 circulates; And agitation means for mixing the grains mounted in the storage chamber 18.

Here, a pedestal 56 is attached to the bottom of the lower plate 12, and a condenser 46 for condensing the refrigerant compressed by the compressor 42 is installed on the upper surface thereof, including a compressor 42 for compressing the refrigerant. do. The condenser 46 is equipped with a cooling fan 44. The refrigerant cooled in the condenser 46 is sent to the tube 50 of the heat exchanger 48 through the pipe 52, and cools the inside of the storage compartment 18 through heat exchange in the course of circulating the tube 50. do.

In addition, one side of the machine room 16 is provided with a partition wall 52. A drawer box 20 is inserted into the partition wall 52, and a slider 26 for selectively opening the outlet 14a in response to the operation of the button 24 is inserted into the spring 28 at the upper part of the partition wall 52. It is arrange | positioned in the pressurized state. The guide plate 54 is disposed above the slider 26 to regulate the longitudinal movement of the slider 26.

Even if the heat exchanger 48 is disposed outside the storage chamber and cold air is supplied, there is a limit to the cold air being transmitted to the center of the storage chamber 18. Therefore, it is good to send the cooled grains in the periphery of the storage chamber 18 to the center and to mix them. To this end, agitation means were installed in the storage chamber 18.

In the constitution of the stirring means employed in the present invention, the motor 36 attached to the upper plate and the drive shaft 38 rotated by the motor 36 are integrally combined to mix the grains in the storage chamber 18. It consists of a screw (40). Here, the motor 36 is fixed to the center of the upper plate 34 as shown in FIG. An injection port 34a for injecting grain into the storage compartment 18 is disposed radially around the central portion 34b of the upper plate 34 on which the motor 36 is mounted. In the present embodiment, four injection holes 34a are formed, but in some cases, even if only one or two are installed, there is no problem in injecting grains. In addition, it is also possible to install the inlet to one side of the outer case 10 so as to be open and close, as in a general household rice bowl.

Demonstrate the principle of long-term storage of grain using the grain storage having this configuration.

In order to inject grain, the cover 32 may be opened, and then grain may be injected through the injection hole 34a formed in the upper plate 34. When the grain is full, the compressor 42 is operated by pressing a button installed in the control operation unit 60. As the compressor 42 operates, compression of the refrigerant begins, and the compressed refrigerant is sent to the condenser 46, cooled, and then supplied through the pipe 52 to the tube 50 of the heat exchanger 48. The inside of the storage chamber 18 is cooled by the refrigerant flowing through the tube 50 to cool the grains.

When the temperature of the outer periphery of the storage chamber 18 decreases to some extent, electricity is supplied to the motor 36 by the control of the control operation unit 60. As the drive shaft 38 is rotated according to the energization of the motor 36, the screw 40 attached to the drive shaft 38 rotates to mix grains in the storage compartment 18. Therefore, the cooled grains around the storage chamber 18 and the grains in the center are agitated with each other, whereby the grains in the storage chamber 18 are always maintained at a constant temperature, thereby enabling long-term storage.

In order to take out the grain stored freshly in this way, the valve means installed in the machine room 16 may be operated. As described above, the valve means is attached to the button 24, which is a hand-pressing part, and attached to the rear of the button 24, and pressed in the state of being pressed by the spring 28 supported by the stopper 30. The slider 26 is formed with a through hole 26a for selectively opening the outlet 14a according to the operation of the button 24. Therefore, when the button 24 is pressed, the through hole 26a is disposed in parallel with the outlet 14a of the guide plate 14 while the slider 26 moves while pressing the spring 28. By communicating, the grains from the storage chamber 18 are stored in the take-out box 20. Withdrawal box 20 containing the grain can be easily withdrawn using the handle (22).

According to the present invention described above, since the screw is mounted in a storage chamber disposed at the upper part of the machine room centering on the guide plate, when the screw is rotated by using a motor, the grains inside are uniformly mixed and stirred. At this time, when cold air is supplied through the heat exchanger surrounding the storage compartment, the temperature in the storage compartment can always be kept below a certain value, so that grains such as rice and beans in the storage compartment can be kept fresh for a long time.
