PROBLEM TO BE SOLVED: To provide a moisture adjustment method of cereals and a moisture accommodation system of cereals for making whole-grain cereals contain moderate moisture without debasing the quality of whole-grain cereals having a husk (e.g., nutrients contained in the whole-grain cereals disappear).SOLUTION: A moisture adjustment method of cereals includes: a decompression step of exhausting a treatment tank in which husked whole-grain cereals have been carried; a pressure recovery step of diluting remaining air in the treatment tank by injecting steam into the treatment tank; a re-deaeration step of increasing the degree of vacuum in the treatment tank by exhausting air in the treatment tank; a temperature raising step of heating the whole-grain cereals to a temperature that does not debase the quality of the whole-grain cereals in the treatment tank (nutrients contained in the whole-grain cereals do not disappear) by injecting saturated steam into the treatment tank; a dew condensation step in which the saturated steam liquefies to condensed water by attaching to the husk of the whole-grain cereals, and the condensed water penetrates into the inner surface in the husk; and a final step of returning the inside of the treatment tank to an atmospheric pressure. |
