ABSTRACT:
A vacuum packaging machine for performing a vacuum sealing operation on product packages, comprises a vertical stack of vacuum chambers4which each manage to receive at least one unsealed product package2and are operable to perform an independent vacuum sealing operation on the least one product package2. A conveyor arrangement8, 9is operable to load and unload a selected vacuum chamber4with the at least one product package, and the machine is arranged to operate the respective vacuum chambers4to perform the vacuum sealing operation while the conveyor arrangement is operated to load and unload another vacuum chamber4. The conveyor arrangement loads and unloads the vacuum chambers in sequence, and the vacuum chambers are synchronously operated to perform the vacuum sealing operation to allow the conveyor arrangement to operate continuously. The conveyor arrangement comprises at least one in-feed conveyor8and at least one out-feed conveyor9which are independently movable to select the vacuum chamber to be loaded and unloaded. There may be a plurality of in-feed conveyors8and a plurality of out-feed conveyors9. The vacuum chambers each have a sealing bar arranged along one side for sealing the product packages2.
