1. A vacuum packaging system for vacuumizing and sealing a plurality of unsealed packages comprising a plurality of vacuum chambers each linked with a respective platen assembly, each platen assembly comprising a platen and a platen conveyor, and each vacuum chamber and platen assembly arranged to receive an unsealed package and operable to perform a vacuum sealing operation on the unsealed package, characterized in that the vacuum packaging system comprises:
a) a conveyor apparatus configured to unload a vacuumized, sealed package from each platen conveyor, and to load an unsealed package onto each platen conveyor, in a linear path, the conveyor apparatus comprising
i) an in-feed conveyor operable to load each platen conveyor with an unsealed package, andii) an out-feed conveyor, disposed downstream of and longitudinally spaced apart from the in-feed conveyor, operable to unload each vacuumized, sealed package from each platen conveyor; and b) a ferris wheel-type vacuum packaging apparatus comprising at least three radially arranged vacuum chambers each linked with a respective platen assembly, each chamber and platen assembly rotatable about a central horizontal axis disposed parallel to the linear path of the conveyor apparatus, the ferris wheel-type vacuum packaging apparatus operable in a vertical plane of rotation disposed perpendicular to the linear path of the conveyor apparatus. |
