Description

High purity rice grain selection method

The present invention relates to a method for sorting high-purity rice sprouts for sorting high-purity rice sprouts, and more specifically, removing foreign substances contained in rice bran, which is a raw material for rice sprouts separated in the grinding process, and then drying, sterilizing, and cooling. In particular, by using a cyclone dust collection method to transport the objects to be sorted, the inflow of foreign substances during the sorting process can be fundamentally blocked and the hygienic process can be maintained, thereby ensuring food safety. It relates to a method of sorting high-purity rice snow.

In recent years, along with the improvement of the economic level, the interest in health and the high quality of dietary life have increased, so that the functional criteria for food selection are also required.

In particular, rice, the raw material of rice, which we use as a staple food, is the grain that the people of Korea consume most as a staple food, consisting of seed and endosperm, and is stored in the form of brown rice with only rice hull removed. Approximately 8% of the rice is milled and processed into white rice, and as the degree of rice is increased, the weight decreases as well as the effective ingredients contained in the rice bran layer are removed.

In the past, there was an increase in yield in the development of rice varieties, but in recent years, the need and interest in rice for processing raw materials or functional rice is increasing. Functional rice is newly added or enhanced with special nutritional value in addition to the original nutrient source to'rice', and it can be said to be a variety or product that has high added value over a certain level.

Various minerals such as gamma oryzanol, octacosanol, alpha-tocopherol, Gaba, lecithin, vitamins (A, B, C, D, E groups), calcium and unsaturated fatty acids (linoleic acid, linolenic acid, oleic acid), dietary fiber, etc. It contains a large amount of physiologically active substances with excellent functions. In particular, Gaba is a component that is being studied as a medicine that improves blood flow to the brain by reducing triglycerides in the blood and enhancing liver function.

As described above, rice sprouts are emerging as a safe and complete food material that cannot be compared with any food due to their high nutritional value, and the development of various functional foods and cosmetics using rice sprouts is being actively studied.

However, rice sprouts are included in a by-product called rice bran, which is a pulverized mixture that occurs in the process of grinding brown rice, and it is mixed with rice bran and other foreign substances in addition to rice sprouts, so it is virtually very difficult to select only pure rice sprouts from rice bran (rice bran). Not only difficult, but also lipase or lipoxidase contained in rice seeds (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 fat, and due to the high oil content of rice grains, quality deterioration due to rancidity during storage is easily caused.

The present invention was created to solve the problems of the prior art as described above, and an object of the present invention is to transport the sorting object through a cyclone dust collection method, and to efficiently remove foreign substances contained in rice bran during the transport process. It is to provide a method for sorting rice sprouts that enables the sorting of rice sprouts containing a large amount of high-purity physiologically active substances.

In addition, the present invention is to provide a method for sorting rice seeds capable of prolonging the storage period by suppressing easily deterioration of the rice seeds selected through drying, sterilization and cooling processes during distribution.

A method for sorting rice grains according to a preferred embodiment of the present invention for realizing the above object includes: a first sorting step of supplying rice bran to a vibrating screen having a size of 15 to 40 mesh and selecting the passed bran particles; A first collecting step of blowing and transporting the bran particles selected in the above step with heated air, collecting the bran particles by cyclone dust collecting, and collecting the bran particles at a high temperature; A second screening step of receiving the bran particles exposed to heated air and dried in the step and selecting specific gravity using wind power; A second collection step of blowing and transporting the rice bran particles selected in the above step by heating air, and collecting them by cyclonic dust collection; A third screening step of receiving the bran particles dried in the step and passing them through a vibrating screen having a size of 30-50 mesh to select bran particles; A third collection step of blowing and transporting the rice bran particles selected in the above step by heating air, and collecting them by cyclonic dust collection; A fourth selection step of receiving the rice bran particles dried in the step and selecting colors using a color sorter; A fourth collection step of transferring the rice bran particles selected in the above step to heated air and collecting them by cyclonic dust collection; It characterized in that it comprises the step of receiving the dry rice grains in the step and blowing high-pressure air to remove dust and foreign substances to obtain rice flour.

As a preferred feature of the present invention, in the first, second, third, and fourth collection steps, the heated air has a sequentially high temperature.

In the method for selecting high-purity rice sprouts according to the present invention, not only can high-purity rice sprouts be obtained in a short time by removing impurities and foreign substances contained in rice bran in a continuous process, but also the selected rice sprouts are processed through heat treatment and sterilization processes to distribute and Since rancidity or deterioration of quality can be easily suppressed during storage, as a result, there is an advantage of commercialization through standardization of the process and mass production.

In addition, it is possible to minimize cracking of rice grains in the process transfer process by allowing the process to be moved by a cyclone dust collection method by hot air instead of the conventional conveyor transfer method or screw transfer method, and by repetitive drying by hot air, high quality It is possible to obtain rice flour, and in particular, as the input of foreign matter can be fundamentally blocked, it is possible to maintain a hygienic process, thereby improving food hygiene.

In addition, gamma oryzanol (promotes brain cell metabolism, promotes energy metabolism, prevents obesity), as well as vitamins B1, B2 (prevents beriberi disease, anti-neuritis, promotes growth, maintains skin/hair health, improves learning ability). And linoleic acid (improving atopic dermatitis, promoting growth, inhibiting cancer cells), dietary fiber (maintaining balance of intestinal bacteria, dilution of heavy metals, pesticides, preventing constipation, reducing the risk of colon cancer), octacosanol (physiologically active function, reducing cholesterol, stiffening arteries) It contains a large amount of active nutrients such as prevention, reduction of body fat percentage and increase of muscle mass), alpha-tocophenol (antioxidant function, prevention of cell aging, improvement of immune function, cardiovascular disease, reduction of risk of cancer/cataract, suppression of dementia), etc. As many active nutrients activate the body's autoimmunity and healing power, long-term use of these nutrients is expected to be effective by health staff.

In addition, rice bran containing rice sprouts in the past was simply used as feedstock for livestock or as a raw material for cosmetics, but as it is possible to obtain high-purity rice sprouts, it is expected that it can contribute to increase in farm income, job creation, and exports.

Step 7: Color-selection of the fine grains collected in step 6 using a color sorter. (s70) Color selection in this step

Uses an image sensor to determine the presence or absence of a color to be selected, and uses a known color sorter that separates good products from foreign substances.

Step 8: The rice bran particles color-selected in step 7 are collected by a cyclone dust collection method by hot air transfer (s80).

Step 9: The bran particles collected in step 8 are removed with high-pressure air to remove dust and residual foreign matter, and air is washed to finally obtain rice flour. (s90)

On the other hand, it is preferable that the temperature at the time of transfer of the hot air in steps 2, 4, 6, and 8 is set to have a high temperature sequentially while proceeding from step 2 to step 8.
