  • Patent number: 6479092
    Abstract: Method and apparatus for infusing fruits (which may include vegetables) with sugar. The apparatus includes a series of interconnected tanks (10, 12, 14, and 16). A stratified column of infusing liquor is caused to flow from a tank (50) via variable output pump (52) through fruit which is placed within the tanks to cause the fruit to become saturated with sugar. In addition, at start-up, frozen fruit is placed in a warming liquid in the tanks prior to infusing, and the infusing liquor will drive the warming liquid in front of it. Fruit juice is removed from the downstream portion of the infusing liquid.

  • Patent number: 6159527
    Abstract: Method and apparatus for infusing fruits (which may include vegetables) with sugar. The apparatus includes a series of interconnected tanks (10, 12, 14 and 16). A stratified column of infusing liquor is caused to flow from a tank (50) via variable output pump (52) through fruit which is placed within the tanks to cause the fruit to become saturated with sugar. In addition, the fruit is placed in a plumping liquid in the tanks prior to infusing and the infusing liquor will drive the plumping liquid in front of it. The fruit may be conditioned in various ways prior to placement in the tanks, which conditioning may remove fruit juice from the fruit, the fruit juice being collected in a tank (36) for subsequent use. Alternatively, if fruit juice is not removed from the fruit during a conditioning process, fruit juice is extracted from the downstream portion of the plumping liquid.

  • Patent number: 6123018
    Abstract: A method and apparatus for extracting liquid from a liquid-containing slurry. In the preferred embodiment, the apparatus (10) includes a plurality of interconnected press assemblies (12), the outlet (82) of one press assembly (12) being connected to the inlet (92) of a successive press assembly (12). Each press assembly has a foraminous cylindrical container (14), and a two-part piston assembly (18) movable between extended and retracted positions within the foraminous container (14). During operation, a pump (90) continuously feeds slurry under pressure through the inlet of the first press assembly to cause liquid within the first stage slurry upstream of the two-part piston assembly (18) to be radially expressed through the foraminous container (14). After a suitable amount of liquid has been extracted from the first stage slurry, batch processing of the partially dewatered slurry will commence.

  • Patent number: 5275097
    Abstract: A press assembly (10) for squeezing liquid from layers of liquid containing materials. The press assembly utilizes a plurality of open top filter bag assemblies (102), each filter bag assembly being disposed between adjacent press racks (86), the press racks being mounted on parallel horizontally extending rods (52) for sliding movement thereon, the rods in turn being supported between spaced apart platens (42, 54). When the press racks are moved towards one another to squeeze juice from the liquid containing material which is disposed within the filter bag assemblies, the juice will flow into a collector (176) mounted below the press racks.

  • Patent number: 5267509
    Abstract: 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.

  • Patent number: 5207152
    Abstract: A compact juice machine (10) of simplified design, the individual elements being simplified to a bare minimum in an easily cleanable package. The machine includes a frame having spaced apart side walls (14, 16) which support front and intermediate rigid platen walls (18, 20) and an upper wall (22) to the rear of the intermediate wall. A press chamber (24) is defined by the forward portion of the side walls and the platen walls. A shredder assembly (36) including a rotatable disk (44) is mounted above the upper wall and a drive motor (48) is mounted below the upper wall, the drive motor having a drive shaft (54) coupled to the shredder disk. A hopper (34) is mounted on the upper wall above the shredder disk.

  • Patent number: 5031524
    Abstract: A fruit and vegetable juice press assembly. The assembly includes a frame (12) which supports a press drive (166, 172, 174) and a food processor drive (120). A removable housing (14) is mounted over the drives, the removable housing including two spaced apart housing portions (76, 78). A platen (170), a press bag (18), and a press bag support (218-248) are located in the pressing chamber between the housing portions. A portion (168) of the press drive extends through an aperture in the sidewall (78.41) of one of the two housing portions, the platen being removably secured to the portion (168). A process (16) is removably secured to the top of the other housing portion (76). The processor includes a grater, an impeller, and a two part or clam-shell discharge chute (100, 106) which, during operation of the grater (84) and impeller (86-90), causes grated pulp material to be discharged into the press bag.

  • Patent number: 4191103
    Abstract: An improved juice extractor is adapted to separate the juice of a fruit pomace from the pulp thereof. The juice extractor has an elongated flexible open-ended sleeve positioned adjacent a bearing or backup surface, and having an entrance end adapted to receive the pomace. The sleeve is formed of a foraminous material permeable to the juice to be extracted, but substantially impermeable to the pulp of such fruit. The cross-sectional area of this sleeve decreases toward its exit end. A plurality of roller members are adapted to press proximate portions of the sleeve against the bearing surface, and are also mounted for movement along the sleeve. The action of the moving roller members causes the pomace to be advanced along the sleeve. Such movement of the roller members, coupled with the decreasing cross-sectional area of the sleeve, gently squeezes the pomace to separate the juice from the pulp. The juice passes through the sleeve and is collected. The pulp is discharged through the exit end of the sleeve.
