  • Patent number: 10287044
    Abstract: An apparatus for filling a produce tray with agricultural produce includes a tray loading station with a fill hopper for receiving the agricultural produce, a produce compression station including at least one tuck finger platen, and a conveyer including a plurality of tray carriers for moving the produce tray from the tray loading station to the produce compression station. Some embodiments of the invention also include a split chute for transferring the agricultural produce from the fill hopper to the produce tray and a trolley for selectively positioning the split chute under the fill hopper or tuck finger platen. Another embodiment of the invention includes a tuck finger platen for compressing agricultural produce near the center of the tray less than agricultural produce near the interior walls of the produce tray. Yet another embodiment of the invention includes steps in a method for loading agricultural produce into a produce tray.

  • Patent number: 7028415
    Abstract: A drying apparatus for use with many kinds of objects, but is particularly suited for use in drying most kinds of produce and vegetables including leaf vegetables. In one embodiment, the dryer includes a canted drum design which provides a number of benefits and advantages over prior art designs. The canted design allows the use of a spin drying method that breaks up clumps of material in the dryer and assists in the even distribution of material, thereby improving load balance. The canted design provides ergonomic advantages to the operator when loading and unloading the dryer, and, the canted design allows easy access to the drive system for maintenance and repairs.

  • Publication number: 20030233765
    Abstract: The present invention is a dryer for use with solid-form objects suitable for a continuous process production environment, such as some kinds of produce and vegetables. The apparatus uses a variable-speed accelerator belt to rapidly load objects. The dryer has a domed shaped retaining door to force objects to the perimeter of the perforated spinning drum. In operation the apparatus uses a method to vary the speed of the accelerator belt to accomplish even self-balanced stacking of the objects within the drum. The method also includes varying the drum rotation speed from a slow rotation during loading, permitting self-balancing of the contents of the drum, to a higher drying speed that extracts liquid from the objects.

  • Patent number: 6371014
    Abstract: The system for peeling a fresh commodity includes barbs for piercing the peel in a plurality of spaced-apart locations. A vacuum infuser is used to infuse the pierced commodity with an aqueous solution to loosen the peel. A peeling device supports a fresh commodity in a first position. The commodity is impelled toward a structure having cutting elements for scoring the peel to a predetermined depth. Preferably the scores are made along generally circumferential lines having substantially common endpoints. Peel grippers hold the peel between the scores and release the peeled commodity, such that the peel is retained on the gripping means. A thruster is positioned and adapted to force the commodity along a path to engage the cutting and peel-gripping elements.

  • Patent number: 5806414
    Abstract: A processing apparatus and method for removing rind from a spheroidal food article, such as a melon is provided. The apparatus includes infeed and outfeed componentry for conveying melons to be processed into and out of the apparatus, providing an apparatus well suited for use in an automated environment. The infeed componentry includes a positioning device for positioning a melon to be processed between revolving mandrels, for achieving a desired orientation of the melon relative to the mandrels. The mandrels retain the melon on its axis and revolve the melon on its equator. Knife members are positioned on either side of the melon and aligned with the equator thereof when the melon is in an initial position. The knife members have detachable blades to accommodate rinds of different thicknesses, so that the blades extend through the rind, without extending into the flesh. Rollers are secured to the knife members to control the cutting depth of the blades and to enhance the ease with which the rind is cut.
