Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to processed rice which can be cooked simply by pouring water, and a method and an apparatus for producing the processed rice, which eliminates the need for washing with water in ordinary households. You can get rice.

[0002]

2. Description of the Related Art At present, rice, which is a so-called non-washed rice, which does not require a washing operation in ordinary households, is in circulation. As a method for producing this rice, which is called unwashed rice, after polishing the polished rice polished by a polished rice mill in an extremely short time, then dewatering and drying the polished rice, and polishing the polished rice polished by the polished rice mill with a polishing brush, rubber roll And a method of rubbing with a rice mill, adding a sticky substance such as starch, bran or sugar to polished rice milled by a rice mill and then wiping them. The above-mentioned method for producing non-washed rice involves removing the aleurone layer (paste layer) remaining in the recesses on the rice grain surface that could not be removed by milling in water, removing it by polishing, removing starch, It is wiped off by bonding with a sticky substance such as bran or sugar.

[0003] In the above-mentioned method of producing unwashed rice by underwater milling, water is brought into contact with rice grains to soften the aleurone layer, and the softened aleurone layer is removed in water by the milling action, and an adhesive substance is added. In the method for producing unwashed rice, the adhesive substance comes into contact with the surface of the rice grains to peel off the aleurone layer. These water and adhesive substances mainly function as a medium for peeling the aleurone layer, and the medium itself does not permeate the rice grains to increase the nutritional value.

[0004] In other words, unwashed rice is compared with brown rice or polished rice because the bran layer is peeled off from the brown rice by milling to form polished rice and the residual aleurone layer adhering to the polished rice is removed. Also, it is considered that protein, lipid, ash, vitamin B1, and other mineral components such as calcium, magnesium, and iron contained in the bran layer and the residual aleurone layer are insufficient (see Table 1).

[0005] Japanese Patent Application Laid-Open No. Hei 5-137521 discloses a solution of gelatin in rice obtained by further polishing and polishing rice to remove the bran completely, or rice in which the rice is completely removed by washing the rice. A coating of gelatin aqueous solution is formed on the surface of rice by coating, dipping, spraying, or the like, and then the moisture is dried to obtain gelatin-coated polished rice. This makes it possible to produce polished rice that does not require washing, and to store the deliciousness and aroma of rice for a long period of time without any loss. However, since the polished rice completely removes the bran, its nutritional value is not particularly high.

Then, in the recycling unit, the white bran separated by the separation unit is supplied to the first mixing unit and the second mixing unit, and the white bran is reused.

In addition to the above-mentioned apparatus, there are agitating and polishing means for supplying mist, steam or moist air to polished rice or rice grains in the process of milling and agitating and polishing, and adding calcium to the agitated rice grains. Mixing means for mixing white bran containing at least one nutrient among magnesium, iron and vitamins; coating means for spraying hot air or steam on rice grains mixed with white bran to coat the rice grain surface; And a recycling unit for supplying the white bran to the mixing unit again to reuse the white bran.The stirring and polishing unit applies mist, steam, or moist air to the milled rice or rice grains in the process of milling. When supplied and stirred, the free bran attached to the rice grain surface softens, and the free bran is removed by cutting to form rice grains that can be cooked just by pouring water. White rice bran containing nutrients such as calcium, iron and vitamins is applied to rice grains that can be cooked just by pouring, and hot air or steam is sprayed on the rice grains coated with white bran by the coating means, and the white bran is pregelatinized to starch. It is possible to produce processed rice that is of high quality, has high nutritional value and can be cooked just by pouring water. Then, in the recycling unit, the white bran separated by the separation unit is supplied to the mixing unit, and the white bran is reused.

In the above apparatus, the agitation polishing means and the coating means are formed by dividing a perforated wall bran tube installed in a machine frame into two parts, and one end is formed as agitation polishing means and the other end is formed as a coating means. In addition, when the main shaft rotatably mounted in the porous wall removing bran cylinder is shared, without using commercially available unwashed rice, from a milled or milled rice grain, a high nutritional value, water It can be continuously produced into cooked rice that can be cooked just by pouring.
