TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing rice flour milling, and a rice flour milling method using the method.

The present invention relates to a manufacturing method and apparatus for milling rice bran by extracting rice bran from rice, and more particularly, to a method and apparatus for milling rice bran to dry (stabilize), cool, A milling method and a milling apparatus.

In general, Rice Bran is separated when rice is cultivated. It refers to rice husk excluding brown rice and its outer part in brown rice. It is known that rice bran contains various active ingredients such as unsaturated fatty acid, protein, carbohydrate, vitamin E, dietary fiber and orizanol, and has various physiological effects including the effect of suppressing the increase of cholesterol.
In the United States and other Western countries, rice has long been applied to foods such as bread, cookies, and snacks to produce health foods, which are stabilized and sold as health foods.
In addition, rice giants, which are essential for the dietary life of Korea, have been mass-produced recently due to the rapid spread of rice processing facilities (239 NPCs, 156 RPCs and 83 RPCs) in the rice processing complex. However, And most of them are used as feeds.
Specifically, domestic rice production is about 4 million tons, of which rice is a mixture of rice bran and rice, about 7 ~ 8%, about 300,000 tons. About 70% of them are used for composting, processing, disposing of feedstuffs, food byproducts, and cosmetics. Only about 30% of them are used for refining rice bran. So they are developing and selling rice bran oil from domestic large companies and small and medium enterprises. Or inexpensive natural vegetable oils.
With the recent FTA with China, the opening of imported rice is likely to become more and more vulnerable to competition in the domestic rice market. The food self-sufficiency rate is about 23%, the wheat self-sufficiency rate is about 2%, the soybean self-sufficiency rate is about 8%, the barley self-sufficiency rate is about 22%, and rice is about 5%.
Rice bran contains 95% of nutrients in rice bran except 5% of nutrients in rice, but it was difficult to get into the spotlight because it was difficult to grill after milling in rice and difficult to grind.
Recently, research on rice bran has shown that rice bran has various physiological activities such as inhibition of cancer and lowering of cholesterol concentration in blood. By extracting these components, it is possible to extract plant polysaccharides of high added value by using rice bran, And it is necessary to carry out studies that can be easily processed into edible products.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a flowchart illustrating the production of rice bran flour by a rice flour milling apparatus according to an embodiment of the present invention.
Prior to the explanation, as an example, the process of obtaining rice gruel from rice collected for understanding is briefly described as follows. In the rice gruel, rice bran and rice gruel are installed in two stages. The rice which is released together with rice hulls can be obtained by using the structure that can be obtained in the second rounding process by dropping into the second rice milling machine and other suitable structures.
Hereinafter, a method for manufacturing a rice germ meal according to a preferred embodiment of the present invention will be described. A cooling step (S200) of cooling the stabilized raw corn; A demineralization step (S300) of milling the cooled rice bran; And a packaging step S400 of packaging the milled rice bran.
The background of the unstable stabilization process in the stabilization process (S100) is as follows. The water content of rice is 13-15%, and the rice hulls are melted during the ripening process. In the process of turning from rice at 0 min to rice at 10-12 min, rice bran and rice blend are mixed with rice at 7 ~ 8%.
At this time, the water content of rice bran contains 13 ~ 14% moisture and rice bran oil. As a result, when the rice bran comes into contact with the air, it rapidly oxidizes and decomposes, and when the water content is in the range of 13% to 15%, it can hardly be crushed into fine particles of 80 to 100 MESH. It is mixed together to become a rice cake, and it becomes lumpy and it is not caught in the mesh mesh, and the hole of the mesh is blocked and the process can not proceed. Therefore, stabilization processing is performed to prevent this.
Specifically, the stabilization treatment of rice bran can be accomplished by passing raw fish through a cylindrical dry dryer at a temperature of 130 to 280 degrees at a rate of 70 to 80 kg per hour to have a water content of about 7%. In this case, the dry dryer is designed to control the heat treatment temperature to prevent rancidity (rice husk is more than 10 minutes at 110 ° C or more, and rice bran is more than 10 minutes at 120 ° C or more).
At this time, if the heating temperature is lower than 130, there arises a problem that the number of general bacteria and rancidity increase more than two times as the preservation period of the rice bran powder is lengthened. When the heating temperature is higher than 280 ° C., there is a problem that the rice bran is carbonized to produce bitter taste in the rice bran-added food, and the nutrients such as proteins, lipids and minerals contained in the rice bran tissue are destroyed Lt; / RTI >
In this step, the soil-derived microorganisms in the rice bran are removed, the insect eggs such as moths are carbonized, and the rice bran is heated for 15 minutes so as to stabilize the increase in the number of ordinary bacteria and rancidity as the storage period increases To 45 minutes.
If the heating time is less than 15 minutes, the insect eggs present in the rice bran are not sufficiently removed, and when a large amount of rice bran is processed at the same time, microbes existing in some rice bran are not removed due to heat gradient . Particularly, when these microorganisms are partially retained, the complete removal is important since the microorganism can proliferate rapidly as the preservation period of the rice bran is elapsed. When the heating time exceeds 45 minutes, the rice bran is carbonized, which may cause bitter taste in the rice bran-added food.
In addition, it is preferable that the raw corpuscles used in the heat treatment step are stored in the temperature range of 0 to 18 ° C within 7 days so as to prevent rancidity due to lipase. This is because, when rice bran is used before the rancidity, it is possible to obtain a fine rice bran powder which is excellent in the quality of the taste and in which the protein denaturation is minimized.

The rice germination cooling step (S200) includes cooling the dry steam passing through the dry dryer sufficiently at room temperature for about 30 minutes.

Next, in step S300, the granulated rice bran is pulverized in a pulverizer of about 30 to 50 horsepower as a rice bran mill, and pulverized slowly at a production rate of 200 kg per hour. At this time, in the pulverizer, the pulverized fine particles are uniformly passed through the cylinder while controlling the moving speed by using the discharge function.
Then, the pulverized rice bran is passed through a 100 mesh sieve, and the moisture in the air can be absorbed, so that it is quickly sealed.
According to the method for producing rice germ powder according to the present invention as described above, the following advantages are provided.
The present invention makes it possible to efficiently mill rice bran when rice is cooked, so it can be used as a health food and hygienically utilized, since it is mostly used as a feed.
In addition, the present invention can solve the supply-demand anxiety due to the rapid increase in international grain demand due to industrialization, solve the instability of international grain production due to climate change, improve the production base and utilization rate of land use, can do.
In addition, the present invention provides a beneficial effect on diabetes, hypertension and constipation as a result of containing a large amount of dietary fiber in rice ghouls, and it is possible to reduce the body weight without side effects by the action of dietary fiber and brown rice nourishment.
In addition, since the present invention is made into powder and the brown rice nourishment is greatly concentrated, it is possible to solve the nutritional imbalance and dietary fiber shortage coming from the instant food.
In addition, the microparticles prepared according to the present invention can be extended up to 24 months within the shelf life of raw fish microbes within a shelf life of 12 months, and the average microbial content can be stored at about 7% And can be applied to a wide range of food, skin, cosmetics and the like. In particular, the organic raw material can play a great role as an organic mushroom cultivation medium.
In addition, the present invention can be widely used as a high-value-added raw material as a raw material for second roasting and fermentation by long-term storage, and in particular, rice bran is mainly supplied to food materials, There is a substitution effect on imports of roughly 54.5 tons of imported rice (based on 15 years), and the effect of replacing imports of US and Australian wheat flour and starch powder is great.
In addition, in the present invention, milled rice is very advantageous for prevention of quality deterioration and cost reduction due to product management through refrigeration and freezing during storage of raw fish.

On the outer surface of the second body part 103, A heating block 150 for applying heat to the second body part 103 is disposed.
Here, when the heating block 150 is disposed inside the second body part 103, the heating block 150 directly applies the heat generated by the heating block 150 to the heating block 150, It is preferable that the heating block 150 is disposed outside the second body portion 103. In this case,
A discharge valve 160 is disposed on the lower surface of the second body part 103 to discharge the dried and sterilized raw material.

Referring to FIG. 4, which is a perspective view of a load sensor unit of the micro-germ-sterilizing dryer shown in FIG. 3, a load sensor unit 170 for measuring the weight of the raw rice contained in the dryer body 110 is provided on the inner surface of the first body unit 101, And the weight of the rice bran was measured at a predetermined interval in the drying / sterilization process to measure the weight of the rice bran at the time of initial acceptance By comparing the weight during drying / sterilization process, it is possible to monitor the optimal drying of rice bran.
