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 γ-aminobutyric acid (GABA) contained in the brown rice is increased.

There is provided a coating solution for rice grains, which can efficiently take in dietary fibre at high concentration and has a high viscosity for efficient coating. In the corresponding apparatus, even if the added amount is large compared to the amount of rice, a large amount of coated rice can be continuously manufactured without causing 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 fibre and one or more kinds of insoluble dietary fibre. The mixture is at a ratio of one part by weight of the soluble dietary fibre and 0.5 to 2 parts by weight of the insoluble dietary fibre. The dilution ratio of the mixture and water is 7 parts by weight of the mixture and 3 parts by weight of the water.

A flour milling method and a flour milling system are provided, in which a plurality of milling steps (4,5, 6,7, 8,9) 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 (4,6,8) and a grading step (5,7,9). The steps are carried out by sorting (3;18) the raw wheat grains into regular wheat grains and material other than the regular wheat grains, forwarding (90) the sorted regular wheat grains to the uppermost-stream milling step, and forwarding (13) 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.

A pretreatment process in a flour milling method in which raw wheat grains are first polished and the polished grains are ground and milled for producing end flour, includes a first, a second, a third polishing step, and a step of adding water. In the first polishing step a pericarp (516) of each wheat grain is removed, in the second polishing step a seed coat (518) of each raw wheat grain is removed, and in the third polishing step a part of cell walls (530) of aleuron layer cells (519) that was in contact with the removed seed coat is removed so that a cell membrane (522) of the aleuron layer cell is caused to be ruptured and that a substance (521) in the aleuron layer cell is caused to be in a state which permits the substance to flow out. In step of adding water, by adding the water to each raw wheat grain, the substance (521) in the aleuron layer cells (519) is caused to flow out from the aleuron layer cells, resulting in producing a polished grain in a state in which the substance (521) in the aleuron layer cell (519) has been separated from each raw wheat grain. It is possible to increase the yield of the end flour collected by the subsequent grinding operation.
摘要:
Raw wheat grains are polished after being subjected to a first water addition and being tempered, and the polished wheat grains are ground after being subjected to a second water addition and being tempered. The first water addition is to cause the raw wheat grains to have a water content of 12 - 14%. The tempering of the raw wheat grains is performed for 16 - 36 hours so that the water sufficiently penetrate into the inside of the raw wheat grains. The method of flouring includes the steps of measuring a water content of the flour obtained by the grinding of the grains, comparing the amount of the measured water content with a predetermined target water content of the flour, and adjusting the amount of water to be added during the second water addition if there is a difference between the measured water content and the predetermined target water content. Thus, it is possible to reduce the time required for the tempering of the polished wheat grains and to adjust the second water addition based on the water content in the flour.
