Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is directed to a brown rice storage and milling apparatus that can store brown rice, polish it as needed, and then use it for consumption.

[Conventional Technology] In order to store brown rice, warehouses that handle large quantities of rice use low-temperature storage warehouses to ensure that the quality of the rice is not compromised. In addition, farmers who own rice for self-consumption and do not have appropriate equipment to store it may store it in paper bags or storage cans, polish it as needed, and make it edible. It was served to

[Problem to be solved by the invention] By the way, low-temperature storage warehouses are expensive and inconvenient for storing rice for home consumption. As food is stored, the following problems occur as the outside temperature rises after May of the year following harvest. In other words, the insects form in one group and devour the stored brown rice. It is also known that fumigation is carried out to prevent the insect damage mentioned above, but in practice it has rarely been carried out due to the smell.

■The respiration of the brown rice itself becomes active, and the fat in the rice itself oxidizes and deteriorates, resulting in a significant decrease in taste.

■Removing brown rice from storage cans was a manual process, and in order to make it edible, it had to be fed into a separate rice mill for polishing, which was extremely inefficient.

[Purpose of the Invention] Therefore, the present invention was made in consideration of solving the above-mentioned problems, by making it easy and efficient to take out the rice from the storage container, and furthermore, by making brown rice that is stored throughout the year more suitable for use outside of the summer. To provide a storage rice milling device for brown rice that is not affected by temperature rise, prevents insects from spawning, and prevents deterioration.

A housing having a heat insulating structure is installed across a 2. air passage, and a discharge port is provided at the bottom of the housing. A storage container, a refrigeration unit provided in a part of the house sink, and a lower end 22 of the storage container for supplying and circulating cold air to the air flow path are connected to each other, and brown rice taken out from the storage container is stored in the storage container. A rice milling device capable of continuously milling rice, a milled rice container for storing polished rice fed out from the rice milling device, a suction fan attached to the rice milling device to suck out rice bran produced during the rice milling process, and a suction fan attached to the rice milling device a rice bran collection device that is connected to separate and collect rice bran;
The present invention is characterized in that a conveyor for charging brown rice into the storage container and a hopper for supplying the conveyor are provided.

[Function] According to this invention, when brown rice for the purpose of storage is put into a hopper and conveyed and stored in a storage container by a conveyor/veyer, the refrigeration unit is set so that the temperature inside the storage container does not exceed a predetermined temperature. Since cold air is supplied and circulated through the air flow path around the outer periphery of the storage container, the temperature of the stored brown rice does not exceed a predetermined temperature, thus preventing insects from disappearing and oxidative deterioration of fat content. do not have. Further, when taking out the rice, by operating the rice milling device by operating a switch, the brown rice can be continuously discharged from the storage container and at the same time, the rice can be milled to obtain the desired amount of polished rice.

゛[Example] The invention of this application will be described in detail below based on the illustrated embodiment.

FIG. 1 is an explanatory diagram showing an embodiment of the present invention. The housing designated by reference numeral 1 includes a refrigerator compartment 1a which is sealed with a heat insulating material 2, and a mechanism room 1 where no heat insulating material 2 is pasted.
It is divided into b. A storage container 3 having a funnel-shaped bottom is installed in the refrigerator compartment la with a predetermined gap from the wall formed by the heat insulating material 2. The lower end 3a of the storage container 3 is formed into a discharge tube extending from the bottom of the refrigerating chamber 1a to the mechanism chamber 1b, and is provided with a shutter 3b for opening and closing.

Furthermore, a refrigeration unit 4 is provided at a position spanning the refrigeration chamber 1a and the mechanism chamber 11), and is installed to radiate heat in the mechanism chamber lb while supplying cold air into the refrigeration chamber la.

That is, the refrigeration unit 4 includes an evaporator 4a in the refrigeration room la, and a pressure rope device 4b and a condenser 4C in the mechanism room lb.

A small rice milling device 5 is connected to the lower end of the discharge tube 3a of the storage container 3. The motor 6 that drives this rice milling device 5 simultaneously drives a suction fan 7 on the opposite shaft.

This suction fan 7 sucks and removes the rice bran generated in the rice polishing device 5, and a rice bran bag 8 provided separately is set 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 is used to filter and collect rice bran from the rice bran-containing air sent by the action of the suction fan 7.

Next, the operation of the second invention will be explained.

First, brown rice, which is to be stored, is input from hopper 11 by selecting a low temperature, low humidity day after autumn. The brown rice is lifted up by the action of the conveyor 100 and carried into the storage container 3 from its upper end (conveyance end). Once the desired amount of brown rice has been delivered, a storage system is entered and operation is controlled by a predetermined control system. That is, in storage operation, it is certain that the temperature at which brown rice does not undergo deterioration is set at about 15°C or lower. The temperature detected is 15℃
When the above conditions are reached, the refrigeration unit 4 is driven for the first time to supply and circulate cold air into the refrigeration compartment 1a. At this time, the fan of the evaporator 4a is constantly operated to circulate cold air.
Only the compressor 4b is turned on and off.

When the detected temperature is 15°C or less, the operation cost is reduced by completely stopping the operation of the refrigeration unit 4. As a result, the brown rice in the storage container 3 is 1
5'C or higher: The temperature will not rise, and there will be no condensation inside due to excessive cooling.
Stable quality can be maintained over a long period of time. If there is a power outage, operation will resume as soon as the power is turned on again.

Then, at the stage of taking out the brown rice for consumption: when the switch of the rice milling device 5 is turned on and the shutter 3b provided on the discharge tube 3a of the storage container 3 is opened, the brown rice continuously flows down and is polished. It is supplied to the device 5. In this case, experiments have shown that it is accurate and practical to control the amount of rice milled by controlling the length of operation time of the rice milling device 5 using a timer.

The rice milling device 5 mills brown rice, feeds the polished rice into a polished rice container 9, and discharges rice bran. This rice bran is
The rice bran is separated by suction by a suction fan 7 driven by a motor 6', passed through a rice bran collection cylinder 7a, set in a rice bran container 8a, and filtered and captured by a rice bran bag 8. collected.

In addition, in the above explanation, the sub-side temperature was set at 15°C, but there is no need to strictly stick to this temperature, and it can be set at 10 to 15°C
A range of practical temperature settings is possible. Furthermore, the shape of the storage container 3 is not limited to a funnel-like shape; instead, a scraper and a conveyor may be provided on the bottom surface to enable the entire storage container to be discharged. Furthermore, the suction fan 7
and a rice bran bag 8 are connected to the front and rear of the rice bran collecting cylinder 7a,
Even if this order is reversed, there is no functional difference.

Further, although not shown, openings are provided at appropriate locations in the housing 1, and lids are provided to cover the openings. For example, the top of the housing 1 has a lid for inspecting the inside of the storage container 3, the front has a lid for loading and unloading the polished rice container 9, a lid for loading and unloading the rice bran bag 8, or a lid for loading and unloading the rice bran bag 8, or a lid for loading and unloading the rice bran bag 8, or a lid for loading and unloading the rice bran bag 8, or a lid for loading and unloading the rice bran bag 8 on the front side.
It is a lid for inspection such as.

[Effects] As described above, the present invention has the following effects.
