摘要

In the present invention, a mastication count "n" is counted by a mastication count calculation means (13b₂) in response to a change in a distance 1 from a photo-reflector (50), such change being received together with a time "t" by a measurement value receiving means (13b₁). Then, a required air pressure is set in accordance with the current mastication count "n", on the basis of a hardness/air pressure correspondence recording unit (13g) that records stages which have a significant difference therebetween and which are stored in correspondence with a mastication count "n", in order to change a hardness "h" of a bag (30) by a perceivable stage in accordance with the mastication count "n". A suction amount of a vacuum pump (20) is controlled in accordance with an air pressure control means (13b₄) in order to achieve the set air pressure inside the bag (30).
