Description

TECHNICAL FIELD The present invention relates to a brown rice storage and rice polishing apparatus capable of storing brown rice, processing the rice to polish it as necessary, and consuming it.

[Prior Art] As a phase of storing brown rice, there has been a cold storage warehouse so that the quality of rice is not impaired in a warehouse that handles a large amount. In addition, there is no proper equipment for storing and storing self-consumed rice like farmers, etc., and they are stored in paper bags or storage cans. Was offered.

[Problems to be Solved by the Invention] By the way, a low-temperature storage warehouse is inconvenient in practical use because it costs much to store home-consumed rice for home use. Since the amount of food to be stored is kept, the following problems occurred as the outside air temperature increased after May of the year after the harvest. In other words, insects hatch and eat brown rice that has been stored. It is also known that fumigation is carried out in order to prevent the above insect damage, but it is rarely carried out due to the fact that it smells.

Breathing of brown rice itself is activated and the fat of the rice itself is oxidatively deteriorated, so that the taste is significantly reduced.

The work of taking out the brown rice from the storage canister is a manual work, and since it has to be put into another rice milling machine to be used for food processing, the rice polishing process is extremely inefficient.

[Object of the Invention] Therefore, the present invention has been made in consideration of the problems described above, and makes it easy and efficient to take out from a storage container. An object of the present invention is to provide a brown rice storage and polishing device that prevents insects from springing and is prevented from deteriorating even when the temperature rises.

[Means for Solving the Problems] In order to achieve this object, the present invention provides a storage container provided with an air flow path in a housing having a heat insulating structure, and a discharge port provided below the air flow path, and the air flow. In order to supply and circulate cold air to the passage, a refrigerating unit provided in a part of the housing, a rice milling device provided to be connected to the lower end of the storage container and capable of continuously processing the brown rice taken out from the storage container, A polished rice container for storing polished rice delivered from the rice polishing device, a suction fan attached to the rice polishing device for sucking rice bran generated in the rice polishing process, and a rice bran that is connected to the suction fan to separate and collect rice bran A collecting device, a conveyor for charging brown rice into the storage container, and a hopper for supplying the same are provided.

[Operation] According to the present invention, when the brown rice intended for storage is put into the hopper and conveyed and stored in the storage container by the conveyor, the refrigeration unit is operated so that the temperature inside the storage container does not exceed a predetermined value. Since at least the cold air is supplied and circulated in the air flow path on the outer periphery of the storage container, the contained brown rice does not exceed a predetermined temperature, so that insects do not hatch and oxidative deterioration of fat content does not occur. Further, at the time of taking out, by operating the rice-polishing device by operating a switch, brown rice can be continuously discharged from the storage container, and at the same time, the rice-polishing process can be performed to obtain a desired amount of polished rice.

[Embodiment] Hereinafter, the invention of this application will be described in detail based on an illustrated embodiment.

FIG. 1 is an explanatory view showing an embodiment for carrying out the present invention. The housing indicated by reference numeral 1 is a refrigerating chamber 1a which is hermetically sealed with a heat insulating material 2 and a mechanism chamber 1b in which the heat insulating material 2 is not attached.
It is divided into Inside the refrigerating chamber 1a, a storage container 3 having a funnel-shaped bottom is installed with a predetermined gap from the wall surface formed of the heat insulating material 2. The lower end portion 3a of the storage container 3 is formed as a discharge cylinder that extends from the bottom surface of the refrigerating chamber 1a to the mechanism chamber 1b, and a shutter 3b for opening and closing is provided.

Further, a refrigerating unit 4 is provided at a position extending over the refrigerating chamber 1a and the mechanism chamber 1b, and equipment is provided to supply cold air into the refrigerating chamber 1a while radiating heat in the mechanism chamber 1b. That is, the refrigerating unit 4 comprises an evaporator 4a in the refrigerating chamber 1a, and a compressor 4b and a condenser 4c in the mechanism chamber 1b.

At the lower end of the discharge tube 3a of the storage container 3, a small rice polishing device 5 is connected and provided. The motor 6 for driving the rice polishing apparatus 5 simultaneously drives the suction fan 7 on the opposite shaft.
The suction fan 7 sucks and removes the rice bran generated in the rice polishing apparatus 5, and sets a rice bran bag 8 separately provided in the rice bran collecting cylinder 7a. The rice bran bag 8 is set in the rice bran container 8a to form a rice bran collecting device, and the rice bran is filtered and collected from the air containing the rice bran sent by the action of the suction fan 7.

Further, reference numeral 9 is a polished rice container for storing the polished rice fed from the rice polishing apparatus 5, 10 is a screw type conveyor which is erected to carry the brown rice into the storage container 3, 11
Is a loading hopper that can be stored in the housing 1 when not in use, and 12 is a motor that drives the conveyor 10.

 Next, the operation of the present invention will be described.

First, the brown rice to be stored is selected from the hopper 11 on the day of low temperature and low humidity after autumn. The brown rice is lifted up by the action of the conveyor 10 and carried into the storage container 3 from the upper end (conveying end) thereof. When a desired amount of brown rice has been carried in, the storage system is entered and the operation is controlled by a predetermined control system. That is,
In storage operation, the temperature at which brown rice does not deteriorate is set to about 15
There is no doubt that the temperature is set below ℃, and an outside air temperature sensor (not shown) is provided inside the mechanism chamber 1b or outside the housing 1, and when the temperature detected by this outside air temperature sensor reaches 15 ° C. or higher, the refrigeration unit 4 is not operated for the first time. Drive it, cold room
