High purity rice snow sorting method {GRAIN SORTING MACHINE}

The present invention relates to a high-purity rice snow screening method for screening high-purity rice snow, and more particularly, to remove foreign substances contained in the rice bran, which is a raw material of rice snow separated in the process of milling, and then to high-purity rice snow through a drying, sterilization, and cooling process. Can be efficiently screened, and in particular, by using cyclone dust collection method, the screening object can be transported to prevent the inflow of foreign substances in the screening process and to maintain hygienic processes, thereby ensuring food safety. The present invention relates to a high purity rice snow sorting method.

Recently, with the improvement of the economic level and the interest in health and high quality of diet, the selection criteria of food is also required.

In particular, rice, which is the raw material of rice that we use as a stock, is a grain most consumed as a stock by Korean people, consisting of seeds and milk. Approximately 8% of the mill is processed into white rice, and as the degree of rice is increased, the weight is reduced and the effective ingredients contained in the rice bran layer are removed.

In the past, the yield was increased in the development of rice varieties, but in recent years, the need for and interest in processed raw or functional rice is increasing. Functional rice is a new addition or reinforcement of special nutritional value in addition to the original nutrient source in the 'rice', and can be referred to as a variety or a product having a commercial value having a certain level or higher value.

Rice eyes include gamma-orizanol, octacosanol, alpha-tocopherol, gaba, lecithin, vitamins (A, B, C, D, E group), calcium, unsaturated fatty acids (linoleic acid, linolenic acid, oleic acid), and various fiber. It contains a large amount of biologically active substances with excellent functions, and in particular, the Gaba component is a component that is currently being studied as a medicine for improving brain blood flow by reducing triglycerides in the blood and enhancing liver function.

As such, rice bran has a high nutritional value and has emerged as a safe and complete food material that can not be compared with any food, and the development of various functional foods and cosmetics using rice bran has been actively studied.

However, rice flakes are separated and included in the byproduct called bran, which is a pulverized mixture produced in the process of milling brown rice.Because rice bran is mixed with rice bran and other foreign substances in addition to rice flakes, it is virtually difficult to select only pure rice bran from rice bran Lipase or lipoxidase (Yamamoto et al., Lipids 15: 1-5, 1980; Luh et al., In rice production, 2nded., AVI, New) York, p. 313, 1991), as well as promoting the decomposition and oxidation of fats due to the high oil content of the rice eye, there is a problem that can not be used as food resources because of the quality degradation caused by rancidity during storage.

Korean Patent Publication No. 10-0362891, p. 4, claim 1.

As a preferred feature of the invention, the heating air in the first, second, third, fourth collecting step is to have a high temperature sequentially.

In the high-purity rice snow sorting method according to the present invention, by removing the impurities and foreign matter contained in the rice bran in a continuous process, it is possible not only to obtain a high-purity rice snow in a short time, but also the selected rice snow is processed through a heat treatment and sterilization process to distribute and It is possible to suppress rancidity or quality deterioration easily during storage, and as a result, commercialization through standardization and mass production of the process is possible.

In addition, the process movement is performed by the cyclone dust collection method by hot wind rather than the conventional conveyor conveying method or screw conveying method, thereby minimizing cracking of rice during the process conveying process, and by repeatedly drying by hot air. It is possible to obtain the rice eye, and in particular, the source can be blocked by the input of the foreign material, it is possible to maintain the hygienic process has the advantage to increase the food hygiene.

Selected rice eyes also contain gamma-orizanol (promoting brain cell metabolism, promoting energy metabolism, preventing obesity), and vitamin B1 and B2 (preventing diseases, anti-neuritis, growth, skin / hair health, and learning). And linoleic acid (improving atopic dermatitis, promoting growth, inhibiting cancer cells), dietary fiber (sustaining intestinal balance, heavy metals, dilution of pesticides, preventing constipation, reducing the risk of colon cancer), octacosanol (physiological activity, cholesterol reduction, arteriosclerosis) It contains high amounts of active nutrients such as prevention, decrease of body fat rate and increase of muscle mass), alphatocophenol (antioxidant function, prevention of cell aging, immune function, cardiovascular disease, reduction of cancer / cataract risk, dementia), etc. Many active nutrients activate the body's autoimmune and healing powers, so long-term health benefits are expected.

In addition, the existing rice bran containing rice bran is simply used as a raw material of livestock feed or cosmetics, but can obtain a high-purity rice snow is expected to contribute to the increase in farm income, job creation and exports.

Step 7: Color discrimination of the rice bran particles collected in step 6 using a color sorter. (S70) In this step, color discrimination is performed by using an image sensor to determine the color of the object to be screened, and to separate the good and the foreign matter. A known color sorter is used.

Step 8: Collecting the rice bran particles selected in the step 7 by the cyclone dust collection method by hot air transfer (s80).

Step 9: The rice bran particles collected in step 8 are removed by dust and residual foreign substances using high pressure air and air-washed to finally obtain rice snow. (S90)
