METHOD FOR IMMERSING GRAINS AND APPARATUS USED THEREFOR

摘要

A method and apparatus for having grains absorb water in a short time without doing any external injury to the grains are disclosed. The immersion method comprises a step wherein grains into which water is to be absorbed and water are put in a pressure-resistant container (10), a step wherein the pressure is reduced in the pressure-resistant container (10) using a vacuum pump (6), and a step wherein the reduced pressure is no longer maintained by opening a reduced pressure releasing opening (4). With this method, it becomes possible to have the grains absorb water in a short time without doing any external injury to the grains. It also becomes possible to have each grain absorb water uniformly from its entire surface.
