  • Patent number: 6776087
    Abstract: A food processing machine having a product cleaning drum and an encircling product carrier shell disposed to define an annular product cleaning space therebetween. A waste collecting bell is concentrically mounted about the carrier shell to provide a waste collecting space therebetween and the carrier shell and collecting bell are interconnected. Separate mechanisms drive the cleaning drum and the interconnected carrier shell and collection bell to alter the magnitude of the centrifugal force that moves the products through the cleaning space and controls the amount of surface pressure applied to the products by abrading members carried on the periphery of the cleaning drum. Centrifugal force and the abrading members coact with frictional surfaces provided in the product movement path to move the products through the machine, while centrifugal force moves waste material from the cleaning space into the waste collecting space and out through a waste discharge mechanism.

  • Patent number: 5682812
    Abstract: The invention provides an improved peeler of fruits such as tomatoes. The peeler passes the tomatoes through a pressure inlet valve to a high temperature stem in a pressurized system. The tomatoes then are passed through a pressure outlet valve to a flexible cable peeler, which helps to remove the peels from the tomatoes. A chute passes the tomatoes from the flexible cable peeler to a pinch roller, which removes the remainder of the peels.

  • Patent number: 5557821
    Abstract: Processing machinery for cleaning, scrubbing, drying, and polishing produce, such as fruits and vegetables, utilizing centrifugal force produced by the relative rotation between a produce receiving rotating disc member and an opposed stationary disc member, both of which have surfaces in the form of brushes cooperating to treat produce that passes between the two brush surfaces to the disc members' periphery. Produce is introduced by a chute communicating with an inner diameter opening in the stationary disc member and falls onto the center of the rotating disc member where the rotating motion creates a centrifugal force urging it outwardly toward the disc members' periphery between the upper and lower brushes. When the produce reaches the disc periphery it drops off and is directed to a common discharge so that the brushes produce a 360 degree discharge of produce to a single discharge path out of the machine. The basic machine arrangement can also be used for drying and polishing produce.

  • Patent number: 5483871
    Abstract: Described is an apparatus and method, particularly applicable to a brush bed conveyor system, by which objects, typically citrus fruit, are washed or sprayed. A moveable high pressure spray manifold is contained within a manifold carriage and is disposed within the conveyor chassis such that it is moved along above a brush bed by a conveyor chain. Separation bars extend from the conveyor chain to segregate the objects into queues retained within the spray pattern of the manifold. When the manifold reaches a predetermined end position, a release latch is decoupled from the separation bars to disconnect the separation bars and conveyor chain from the manifold carriage. The predetermined end position is sensed and the manifold carriage is quickly returned to its initial position by means of a selectively activated pneumatic piston assembly.

  • Patent number: 5148738
    Abstract: A method and apparatus are disclosed for treating fresh fruit to prevent and retard the growth of fungus. The techniques of the invention include simultaneously scrubbing the fresh fruit while drenching with a falling liquid containing a fungicide. Large volumes of liquid are used and the liquid can be recycled. The liquid also removes dirt and debris and, while containing a rather small amount of fungicide, such amount is present in a concentration sufficient to apply a coating to the fruit at the end of the scrubbing step given proper pH control. The pH of the solution is controlled. During the scrubbing step, the fruit is continuously rotated to provide even fungicidal deposit.

  • Patent number: 5106641
    Abstract: Apparatus for cleaning and peeling food products, such as fruits and vegetables, without the use of water, comprises a stationary housing in which a motor-driven brush cage is rotatably mounted. The cage comprises a plurality of cylindrical roller brushes radially arranged about a generally horizontal (but slightly downward slope) axis to define a generally cylindrical product-processing chamber. A rotatable product inlet tube at the chamber inlet end directs the product into the product chamber. A motor rotatably drives the inlet tube and the cage in one direction and, through a stationary ring gear and pinion gears on the brushes, causes each brush to rotate in the opposite direction. The inlet tube has vanes inside which impart initial rotary motion to the product entering the chamber. Product accumulating in the chamber forms a single layer against the wall of the chamber as it is advanced therethrough, making contact with substantially all the rotating brushes which effect cleaning and peeling.

  • Patent number: 4842883
    Abstract: An apparatus and method for continuously peeling and removing dirt from produce wherein the apparatus comprises an abrading cage with a plurality of rotating spindles and having an internal chamber with an inwardly facing abrading surface and an axis of rotation. The axis of rotation of the cage is generally horizontally aligned, as opposed to being vertically aligned so as to vary the combined force due to gravity and centrifugal force acting upon produce within the cage. The cage is rotated at sufficient speed to substantially maintain the produce in contact with the abrading surface during revolution thereof yet the combined force acting upon the produce varies throughout the revolution so as to prevent clustering and bridging. A peel and dirt collecting drum diverges from one end to a wide end, is rotated and is positioned radially outward from the cage and has a surface thereon positioned to receive debris flung outwardly from the cage.

    Abstract: Method for removing material from the surface of fruits and vegetables (produce) and separating the removed material from the resultant mixture utilizes the rotation of an upwardly directed cage formed of elongated rotating spindles having a material removing surface thereon, the cage rotary speed being sufficient, at the interior radius thereof, to maintain the produce in continuous centrifugal force contact against the spindle material removing surface, but generally insufficient to prevent downward movement or migration of the produce within the cage under the force of gravity. Produce to be treated is urged into engagement with the spindles and the rotating cage causes the produce to accelerate substantially to said rotary speed, whereby the produce travels with the cage in contact with the rotating material removing spindle surfaces.
