Description

Rice-cleaning method using ionized water.

The present invention relates to a method for washing rice using ionized water, and more particularly, to a method for washing rice that can wash various germs and foreign substances on the surface of rice using acidic ionized water and alkaline ionized water. Rice is produced in many countries as an important food resource not only in Korea but also in Southeast Asia and other countries around the world. Rice production has soared due to the development of agricultural technology, which has made it possible to provide self-sufficiency of rice in the 1980s, but with economic growth, people's preference for quality taste is higher than ever. Therefore, not only are they spurring on the development of high quality rice, but they are also making efforts to improve the quality by improving the drying, storage and milling methods after harvesting. Once harvested, the rice must be stored in any form until the next harvesting season. Only about 20% of the grains are lost to crops during the storage of cereals. The amount is estimated to be substantial. Therefore, improving the storage stability of grains by developing appropriate processing methods to prevent quality damage of rice could be an indirect food production plan.

Conventionally, the rice was produced through the process as shown in FIG. 1, and the rice is schematically explained in order as follows.

Put rice into raw material tank (2) by means of transportation (1) and store it → Raw rice, straw, earth and sand, grass seed, set tank and stone mixed with raw rice by raw material selection and multi-purpose separator (3) Removal → De-separation of rice which has been selected in the raw material selection and the evaporator in the rice mill (4) (The rice mill is equipped with a main roller that is rotated by the power from the motor and a roller connected to it) → Special in the separator (5) By separating the same mass by vibrating the separating plate, it is divided into three kinds of rice, brown rice, and combination of rice and brown rice by adjusting the inclination angle of the separating plate → Separate and remove the stone mixed in the brown rice in the stoneware (6) → Storage of brown rice in brown tank (7) (brown rice for removing stones through an excavator) → 8 minutes to 12 minutes by exfoliation of embryos, seedlings, endosperm, starch layer, starch layer, etc. Processed rice from Bundo → Crusher (10) Sift out the crushed rice produced during the processing of 8 to 12 minutes of rice.The color sorter 11 sorts out defective products (colored grains, sami, black spots, pellets) with compressed air. Heat damage, colored lip, etc., which are mixed to reduce the value of the product, are sorted by using the color difference between the complete lip and the colored lip, that is, compared with the preset color (complete lip) → Washing the rice surface in the tailing machine 12 → Tank (13) → Packing Machine (14).

Rice is produced through a series of processes as described above, and the surface of the processed rice is attached to the river and foreign matters, resulting in rapid moisture absorption and rapid incubation of microorganisms and molds. Not only is this easy, it also causes the hassle and loss of nutrients to be washed several times during cooking.

In order to remove the steel and foreign matters attached to the rice surface, wet milling is used as a method of crushing rice at the finishing stage of the rice milling process. Removing and softening the surface layer of the rice is sent to the netting tank is performed in the rice mill 12.

In the conventional rice taste method by tap water as described above, there is a drawback that bacteria are multiplied and deterioration of rice, resulting in deterioration of taste and loss of nutrients. The gamma-irradiation of 30-50krad. Suppresses the reproduction of pests and reduces the nutritional value at this dose, but in the case of gamma-irradiated rice, the amylose content and fatty acid level of starch increase with increasing dose. Riboflavine is significantly destroyed. The use of this method should be carefully adjusted for doses in Southeast Asia, as gamma irradiation may induce free radicals to promote the oxidation of oils and fats. The parboil method is used to disperse an enzyme that causes rancidity of oils and fats since the rice is once dried and dried. Has the advantage. Therefore, it is expected that the stability of fat, which has a primary effect on the chemical deterioration of rice during storage, will be improved. However, this method has a drawback that is not suitable for the diet of Korea. Its purpose is to meet the demand and to improve the storage stability of rice. As an introduction technology, the water of wet mill is introduced at the final stage of the mill to remove the steel and foreign matters attached to the surface of rice. It is intended to increase the shelf life of rice by annually washing with acidic and alkaline water instead of groundwater or tap water. Acidic water has a bactericidal effect, which reduces the action of microorganisms on the surface of rice. Rice treated with acidic water by improving storage and treating with alkaline ionized water Giving back the pH to normal can be polished by this process and clean the rice will promote a luxury that can improve the taste of the rice.

The present invention is a conventional rice production method as described above, in particular, even after the process in the rice milling process has no bactericidal effect, the river and the foreign matter adhered to the surface of the rice as it is, the moisture absorption is fast and the habitat environment of microorganisms and molds is formed, Its purpose is to eliminate the hassle that needs to be washed repeatedly over several times when cooking. It is used for 2 years to remove the steel and foreign substances by sterilizing effect by using the deionized process with alkaline ionized water and acidic ionized water for long-term storage. Edo prevents deterioration and does not require washing again at the time of cooking.

The present invention will be described in detail with reference to the accompanying drawings.

The present invention, in order to produce rice through a grinding machine (8), a rice polisher (9), a color sorter (11), etc. sequentially, the acidic ionized water and alkaline ionized water in the first and second secondary polishing machine (16) It is characterized in that to wash the rice to be transferred to the white rice tank (13).

The production method of ionized water is as follows.

If a special diaphragm is installed in the center of the container containing water, it is divided into groups A and B, and calcium A is added to group A to add a Furus electrode, and a negative electrode is provided to Group B to supply power. carbonate ion (Co ₃ ^2-), chloride ion (Cl ^-), sulfur ion (So ₄ ^2-), and the negative ions are gathered acidic water such as, sets the negative electrode B is calcium (Ca ^2+), magnesium (Mg ²⁺ ), alkaline ionized water in which positive ions, such as potassium (K ⁺ ) and sodium (Na ⁺ ), are collected.

In Japan, alkaline ionized water purifiers are formally called electrolytic water generators or electrolytic ionized water generators, and as medical substance generators, alkaline ionized water and acidic ionized water are recognized for their medical effects. It is recognized as effective for chronic diarrhea, indigestion, and antacids.

Alkaline ionized water is an alkaline substance around P.H 8.5 ~ 10.5 and contains a lot of minerals in water, so that it dissolves material, has high extraction ability, and improves thermal conductivity. Therefore, alkaline ionized water plays a beneficial role in the body. For example, by dissolving nutrients in a form that is easy to react, it is well transported to the tissues of the whole body, and the energy change of nutrients is high, and metabolism is active, helping to improve the constitution without getting sick.

Acidic ionized water is an acidic product of P.H 4 ~ 5.5 and used as astringent water with the function of converging protein, washing ability and bactericidal effect.

The well-known hot spring water, which is said to be good for health beauty, also has weak acidity, and the skin is slippery when bathed with such water.

Alkaline water promotes growth and is resistant to pests when sprayed on crops.

On the other hand, acidic ionized water has the effect of sterilization and insecticide.

In the present invention, the groundwater is washed with acidic water of turbidity 110 for 30 seconds in the first tailing mill 15 for sterilization and insecticidal treatment, and dried after being polished with alkaline ionized water in the second tailing mill 16. The bad smell of the old rice is caused by the deterioration caused by the free fatty acids contained in the rice. The result of measuring the fatty acidity, which is a measure of the deterioration caused by the free fatty acids, is shown in Example 3. When the rice was stored at room temperature for 8 weeks, the lipid acidity increased sharply compared to rice. The acidity of the treated rice was lower than that of ordinary rice, and especially the acid and alkali treatments were lower due to the longer storage period. It can be seen that the method increases the shelf life of rice.

The present invention has the effect of sterilization and insecticidal at the same time as the removal of various foreign substances adhering to the surface of the rice by softening with acidic ionized water and alkaline ionized water in the first and second smokers (15) and secondary smokers 16, respectively. Edo prevents deterioration and changes the acidic constitution of our body into an alkaline constitution that has the effect of increasing resistance to disease.
