  • Publication number: 20200170266
    Abstract: A separation and singulation system for presenting shrimps or other product individually to a processor. The separation and singulation system includes a divider pan that separates a layer of shrimp into several lanes, a shaker pan that receives the lanes of shrimp and agitates them to separate clumps of shrimp and a flume for providing further singulation and acceleration of the shrimp. The singulated, separated shrimps are then sent to a processor.

  • Patent number: 10407245
    Abstract: A continuous product-processing apparatus having a conveyor capable of repositioning product and cleaning itself of debris and a method for its operation. The apparatus includes a conveyor that transports products atop a conveyor belt along a carryway to a processing chamber. Upper and lower diverting rollers guide the belt along an S-shaped product-repositioning path segment of the carryway. The diverting rollers are rotated at a speed normally greater than the speed of the conveyor belt to cause the belt to slip on the roller's periphery, which effects a scraping action against the conveying side of the belt to dislodge debris from the belt and the rollers. One-way ratcheting drives or belt restricters positioned on the product-positioning path segment to limit belt excursion are used to prevent the belt from building up along the carryway and tightening in the lower return.

  • Patent number: 10112780
    Abstract: A flexible scraper for a grader or other solid object processing system. The flexible scraper is adjustably mounted to a frame and contacts a rotating roller to clean the rotating roller or prevent components from wrapping around the roller, as well as maintain products within designated lanes. Connectors allow insertion and release of the scraper into and from the frame. The flexible scraper is inserted into slots in the frame and held against the rotating roller by gravity.

  • Patent number: 9837870
    Abstract: A water-resistant electric motor having an end bell with a passage that prevents the formation of a vacuum between the shaft seal and the shaft bearing. The passage extends from the interior region of the motor through the end bell bypassing the bearing to communicate with a gap between the seal and the bearing. The motor housing includes a vent to expose the motor's interior region and the gap to atmospheric pressure or to a source of higher-pressure air or gas to prevent water from being sucked into the motor's interior.

  • Patent number: 9814247
    Abstract: A deveining system efficiently removes veins from shrimp while preserving the meat of the shrimp in both appearance and quantity. The deveining system comprises an endless deveining wall having outwardly-extending snagging tabs. Water flooding a deveining region creates a vacuum effect to pull exposed veins through openings formed by the snagging tabs, followed by separation of the body of the shrimp from the veins.

  • Patent number: 9622494
    Abstract: A shrimp deveining machine with adjustable blades. The deveiner has an inclined trough with groups of blades arranged in a zig-zag pattern. The trough is lubricated by water to help shrimps advance along the blades, which slit the shrimps' backs to expose their veins. Blade-height adjusters adjust the height of the blades above the trough. Blade-angle adjusters adjust the angles of the blades relative to the length direction of the trough. Magnets are used to hold the blades in place for easy replacement. A feed tank at the entrance to the trough includes a serpentine path to separate the shrimps.

  • Patent number: 9456617
    Abstract: A deveining device efficiently removes veins from shrimp while preserving the meat of the shrimp in both appearance and quantity. The deveining device comprises a channel having a blade extending along a section of the channel for cutting the back of the shrimp as it rolls through the channel to expose a vein. A downstream vein remover severs the exposed vein from the shrimp body. Nozzles spray fluid into the channel to propel the shrimp through the channel.

  • Patent number: 9345248
    Abstract: Peeling apparatus and cam followers for lowering and raising the finger frames of roller-type peeling apparatus. The cam followers have monolithic hardened stainless steel cam rollers with journals extending outward of central wheels into bronze bushings retained stationarily in holders. The monolithic cam rollers roll on pivoting cams at the four corners of the finger frame to raise and lower the finger frame in synchrony with the back and forth rotation of peeling rollers forming peeling channels. Support rollers supporting the ends of the peeling rollers also rotate in stationary bronze bushings.

  • Patent number: 9332769
    Abstract: A roller-type peeler having a rack gear retractable for servicing peeler rollers and a method for servicing peeler rollers by retracting the rack gear. A jack attached to the rack gear allows an operator to jack the rack gear up to a service position and out of engagement with roller gears so that the rollers can be removed and replaced and to lower the rack gear back into engagement with the gears of the replaced rollers.

  • Patent number: 8985341
    Abstract: Apparatus and methods for grading products and forming predetermined mixes of graded products. Graders sort products into different grades. The graded products are formed into batches of known quantity. Each batch is designated for deposit in a bin specified to have a certain mixture of graded products. A conveyor conveys the batches to the designated bin. The quantity of each batch is determined by count or weight.

  • Publication number: 20150068223
    Abstract: A counterflow chiller for cooling products on a conveyor employs a plurality of recirculating cooling modules in fluid communication with each other. Each recirculating cooling module sprays coolant over a portion of the conveyor to adjust the temperature of a product on the conveyor. An axial pump pumps coolant from a reservoir in a first recirculating coolant module to a sprayer, which sprays coolant over the product. Overflow coolant spills from one recirculating cooling module to another recirculating cooling module operating at a higher equilibrium temperature.
