Coating solution, method and apparatus

摘要

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.
