Vacuum seasoning device

A vacuum seasoning device which comprises a support stand (1) having a base (11), a container (2) located on said base, said support stand having a support column (12) on one side of said base, a main body casing (3) rotatably supported by said support column, said main body casing having side frame (31), a housing (32) projecting horizontally therefrom, and a base plate (33) projecting parallel thereto and below said housing (32), said side frame being pivotally supported at the lower edge thereof on said support column, whereby said body casing shifts its position between horizontal and a predetermined dihedral positive angle at its front end;

• said base plate, when positioned horizontally, serving as the lid to tightly contact the top opening edge of said container;
• a vacuum pump apparatus to decompress the interior of said container;
• which apparatus comprises a vacuum pump having a cylinder (5), a piston (4) located in said housing, piston rod (43), means of reciprocating said piston rod in said cylinder;
• a unidirectional suction valve (53) which sucks air into the cylinder and a unidirectional discharge check valve (61), said discharge check valve being located in said housing (32), said unidirectional suction valve (53) being located at the bottom of the cylinder whereby it does not interfere with the tight contact between the piston and the opposite surface at the bottom base of the cylinder at the time the piston moves forwardly, said unidirectional discharge valve communicating with the outside air;
• suction ports (33) bored through said base place (33), said suction ports having a suction channel (55);
• a release valve located on a part of said suction channel to release air from said container through said suction ports.
