VACUUM PACKAGING APPARATUS

摘要

A vacuum packaging apparatus is provided for use in evacuating the air in an open-ended package and sealing the evacuated package. The apparatus includes structure defining a chamber sized only for receipt of the open end of the package with the remainder of the package disposed outside of the chamber, and a vacuum pump for evacuating the chamber and the package through the open end. The apparatus also includes a heating element for sealing the open end of the bag. The sealing element includes a seal bar supported for movement within the chamber between a retracted position removed from pressing engagement with the package and an extended position in pressing engagement with the package and a sealing wire supported on and extending across the seal bar. An electrical circuit supplies current to the sealing wire for heating the wire to a temperature sufficient to seal the package when the seal bar is in pressing engagement with the package.
