Abstract: Raw material rice (brown rice and partially-milled rice) is subjected to a preliminary pressurized steam-boiling process to form an alpharized layer on the surface of the raw material rice, and then a moisture adding process is performed. Since the surface of the raw material rice is alpharized to become stiff with the preliminary pressurized steam-boiling process, even rapid moisture addition does not cause a crack in the raw material rice. Therefore, water absorption can be quickly achieved to a target moisture content, thereby reducing a moisture adding time. Also, with no crack, quick-cooking rice with an excellent outer appearance of rice as a product and without a drain of nutrients in rice grains at the time of rice cooking.

According to this method, the coating solution having high viscosity can be obtained. According to this apparatus, even if the added amount is larger compared to the amount of rice, a large amount of coated rice can be continuously manufactured without causing the clogging in the flow of rice and the coating solution in the apparatus and the binding of rice. The coating solution is added at a ratio of 6.0 to 8.0% by weight to rice. The coating solution is made of a water solution of a mixture of one or more kinds of soluble dietary fiber and one or more kinds of insoluble dietary fiber. The mixture is at a ratio of one part by weight of the soluble dietary fiber and 0.5 to 2 parts by weight of the insoluble dietary fiber.

Abstract: A method of producing parboiled rice that does not require waste water treatment equipment and that enriches the amount of ?-aminobutyric acid contained in the parboiled rice. The method includes partially milling raw material brown rice, wetting the partially milled rice grains by forced-air using moist air or mist, moisture-tempering the wetted rice grains, steam-boiling the water-tempered rice grains at normal pressure to heat the rice grains with steam, steam-boiling the rice grains heated in the normal pressure steam-boiling process using pressurized steam, cooling the rice grains steamed under pressure in the pressurized steam-boiling step to cool at least a surface of the rice grains, finish milling the rice grains cooled in the cooling step, and drying the finish-milled rice grains.

Abstract: Milled rice grains are primarily immersed, and at least surface layers of the grains are converted to the alpha-type. The rice grains are then preliminarily dried and consummatively polished, and are further subjected to secondary immersing and secondary alpha-type conversion. During these processes, there occurs no cracking on the surfaces of the rice grains. The consummatively polished rice grains are then separated into individual single grains. The separated individual single grains are finally dried whereby the finished product of instant rice is obtained. The instant rice containing polished rice has good appearance and quality.

Abstract: By use of a device having a construction similar to that of a grain dryer, high-humidity air is applied to brown rice that is being transferred in a circulating manner through the device, the moisture of the brown rice is increased at water addition rates of 0.1 to 0.3%/hour in the range of 16.5 to 18.5% and the brown rice is thereafter left at rest in the device, in a state where blowing of air and circulated transfer of the brown rice are stopped. As a result, the functional component of ?-aminobutyric acid (GABA) contained in the brown rice is increased.

Abstract: Warm and wet air are applied to brown rice with germinated germs, produced by adding water to the brown rice, for removing water attached to a surface of the rice. A surface of the germinated brown rice is polished by a rice-polishing machine while remaining the germinated germs to obtain rice with germinated germs. Water of about 1 to 10% of rice weight is added to soften the rice surface. The rice and granules whose granule size is set to a constant granule size smaller than that of the rice and which is heated to 60° C. or higher are mixed with the rice and stirred. Rice bran remaining on a rice surface after polishing is absorbed by the granules and is removed. And, the rice and granules are separated from each other.

Abstract: A flour milling method and a flour milling system are provided, in which a plurality of milling steps whose milling degrees are different from one another are performed sequentially from an upperstream to a downstream, each of the milling steps including a breaking step and a grading step. The steps are carried out by sorting the raw wheat grains into regular wheat grains and material other than the regular wheat grains, forwarding the sorted regular wheat grains to the uppermost-stream milling step, and forwarding the sorted material other than the regular wheat grains to at least one of downstream milling steps at a downstream of the uppermost-stream milling step. The method and the system enable the production of wheat flour of better quality with better yield than that conventionally produced.
