ABSTRACT:
A vacuum packaging apparatus is provided for use in evacuating the air in an open package and sealing the evacuated package. The apparatus includes a chamber and a lid movable between an open position exposing the chamber and a closed position sealing the chamber. A sealing assembly is provided for sealing the package after air in the chamber has been evacuated. The sealing assembly includes a seal bar movable between a retracted position removed from pressing engagement with the package and an extended position in pressing engagement with the package. A piston of a piston and cylinder assembly is attached to the seal bar in a manner providing an electrical circuit through a sealing wire extending across the seal bar. The piston and seal bar are connected together in such a way as to permit the seal bar to be detached from the piston and removed from the apparatus.
