A method and an apparatus that can allow grains to absorb water in a short time without scratching the same at all are provided. <??>An immersion method includes a step of storing grains for water absorption and water within a pressure-resistant container 10, a step of reducing the pressure in the pressure-resistant container 10 by a vacuum pump 6, and a step of releasing the reduced pressure by opening a reduced pressure releasing port 4. Accordingly, the grains can absorb water in a short time without being scratched at all. It becomes also possible to allow the grains to absorb water uniformly through the entire surfaces of the grains. <IMAGE> |
