摘要：A method and apparatus are disclosed for sealing pallets of fresh produceinside plastic bags and furnishing the interiors of the sealed bags with a modified gaseousatmosphere. Conventional pallets loaded with cooled fresh produce are moved by aninput conveyor 12 automatically one at a time to an in-line squeeze station 16. Theproduce load of a pallet positioned at the squeeze station is squeezed between opposedvertical walls to suspend it above the pallet base as a downwardly movable floorplatedescends to allow the base to be removed and replaced with a pallet having a plasticsheet lining attached thereto. The floorplate is raised to its former level to bear theweight of the loaded pallet as the pallet is unsqueezed and the loaded pallet is movedby conveyor to a bagging station. A plastic bag at a convenient height is initially drapedover an arm 20 radiating from a novel bagger frame 22. A plurality of such arms extendfrom a rotatable hub so that bags can be moved into position above successive loadedpallets as they are needed. This apparatus permits the bagging of nearly twice as manypallets in a given time period. Following the bagging step the bagged pallet is moved toa turntable 26 and sealed by rotation against spring-loaded overlapping strips of tape.After being moved automatically to a gassing station 28, the sealed bag is first evacuated

and then filled with a suitably modified gaseous atmosphere using a Tectrol AtmosphereInjection Unit 30. The gassed pallet is reoriented through 90 by a repositioning turntable32 and sent down an inclined roller-surfaced table 36 to a pallet exit area. In addition toallowing the processing of more units in less time than is possible with present systems,the method and apparatus of the invention require fewer workers to effect the improvedresults.
