The device at the shell for packing into modified atmosphere products placed in trays

摘要

1. A device with opposite shells for packing in modified atmosphere of products placed in trays, comprising a downwardly open upper shell (1) comprising welding means (5), and preferably also comprising means (6) cutting the barrier film (H) for sealing trays, and an upwardly open lower shell (8) with chamber (9) having at least one seat (10) for placing the tray (V), which can be moved on this seat and from it, and also comprising positioning means stretched film portion (H) between the two shells (1, 8) of the trays (V), as well as means information of said shells to each other to grip therebetween the tray edges and said film over these edges and comprising means which are activated at the right time to remove air from the tray and subsequent introduction of processing gases into it for conservation of the product placed in a tray before carrying out the subsequent stage of welding the film to the edge of the tray and then cutting the film on the perimeter portion that is welded to the tray, characterized in that are provided means for operation so that said shell (1, 8) formed within a main chamber (P), bounded above film (H) for covering the tray bottom - a tray (V), containing a product (M), and the side - any suitable structure mechanical interface surrounding the perimeter of said film and connecting it with the perimeter of the upper edge (B) of the tray, whereby this coupling structure provided with holes and / or slots (22) which are suitably distributed and arranged outside the perimeter of the tray and which communicate with said founded
