摘要 |
A vacuum packaging apparatus (10) 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 (36) 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 (68) for evacuating the chamber (36) 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 (84) 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 (86) supported on and extending across the seal bar. An electrical circuit (94) supplies current to the sealing wire (86) for heating the wire to a temperature sufficient to seal the package when the seal bar (84) is in pressing engagement with the package. |
