A novel filter bag assembly (10) which may be used in a press (12) for squeezing juice from fruit. The bag assembly facilitates the discharge of a press cake (PC) from within the bag when it is inverted. The bag assembly includes a bag (50) and an inner liner made from a plurality of flaps (64, 65, 66), there being at least two flaps on each of the wide sides (58, 60) of the bag, the flaps being arranged in a tiered fashion so that the lower edge of one flap will overlie the top edge of an adjacent flap. The bag assembly is utilized with a press having a plurality of press racks or plates (14) which are mounted for movement towards and away from each other and also for movement from an upright normal position to an inverted position, each rack carrying first mounting structure (68) on the top edge (14.1) of the rack, the bag assemblies being provided with second mounting structure which cooperate with the first mounting structure so that the bag assemblies may be supported by and between adjacent racks. First retaining structure (76) is carried by the bottom edges (14.3) of the press racks, and second retaining structure (80) is carried by the bottom (52) of the bags, the retaining structures engaging each other so that when the racks are inverted the bottom of the bag will not drop permitting the press cake within the bag to peel away from the liner and drop from the bag. |
