  • Publication number: 20150059117
    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.

  • Publication number: 20140197088
    Abstract: A self-floating skimmer that can operate remotely from a vessel. Pontoons allow the skimmer to float at the surface of a body of water. An inclined belt conveyor whose lower end is submerged just below the surface of the water conveys material to be collected up the incline to the upper end where it is dumped from the surface of the belt into a collection tank below. For convenience in storage or transit, the skimmers can be stacked atop one another. The belt conveyor can include a bidirectional conveyor belt that is driven in either direction by a selectively reversible drive motor.

  • Publication number: 20140187132
    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.

  • Publication number: 20140166552
    Abstract: Apparatus and method for separating lightweight waste from product with air supplied by a plenum. An air separator includes a blower duct directing air upward through product conveyed on a foraminous conveyor. The blower duct is in communication with a plenum through an opening. One or more blowers fill and pressurize the plenum with air without blowing the air directly through the opening. The drop in pressure from the plenum to the exit end of the duct draws air uniformly through the opening and into the duct. The uniform flow of air through the duct and the conveyor lifts lightweight waste from the product.

  • Publication number: 20140131172
    Abstract: An improved feed mechanism for a processor of solid objects includes a plunging paddle connected via connectors and eccentrics to a rotating shaft driven by a motor. The rotating shaft has an axis offset from the centers of the eccentrics. The plunging paddle plunges product on a conveyor belt from a feed tank to create a single layer for conveying the product to a processor.

  • Patent number: 8720695
    Abstract: A roller-type grader having adjustable, widening gauging passages between consecutive rotating grader rollers and an associated method for adjusting the gauging passages. A drive rotates all the rollers in the same direction on their axes. The ends of the rollers at each end are rotatably and pivotally suspended from adjustment yokes that are movable laterally in unison along tracks by an adjustment shaft. Positioning the yokes positions the ends of the rollers relative to each other. Minimum and maximum widths of the gauging passages at opposite ends of the rollers are adjusted by rotating the adjustment shafts.

  • Patent number: 8640878
    Abstract: A tilt roller grader for grading solid objects, such as shrimp. The grader has grading rollers obliquely arranged across a tilted grading bed. Jacks in cross members supporting the bed are used to jack up the grading bed across its width to adjust the flatness of the bed for uniform grading gaps between the grading rollers and the bed.

  • Publication number: 20130313169
    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.

  • Patent number: 7712202
    Abstract: A system for securing a basket containing product securely within an autoclave or retort. The preferred embodiment of the present invention is used with rotational retorts, which generally include a rotational insert for receiving product-loaded baskets, the rotational insert rotated via a drive to rotate the baskets end over end during the autoclave process, for more efficient heat transfer. The present invention contemplates an improvement for securing the baskets within the retort, to facilitate secure rotation of the baskets and their contents, and prevent shifting of the baskets within the retort during rotation. Particularly, the preferred embodiment of the present invention contemplates the use of one or more lift bladders sandwiched between clamping platens situated along the length of the rotational insert, the lift bladders configured to expand to lift and position the baskets into a securing position for rotation, then deflate to release the baskets after processing for removal.

  • Patent number: 7055678
    Abstract: A modular conveyor belt forming a hinge between consecutive belt rows (14A–C) hingedly connected by a noncircular hinge pin (34). Hinge eyes (28) along the forward and rearward ends of each row (14A–C) of belt modules include aligned openings for the hinge pins (34). The belt rows (14A–C) are arranged end-to-end with the hinge eyes (28) of adjacent rows interleaved. In one version, the hinge pins (34) are inserted in the passageway formed by the aligned openings of the interleaved hinge eyes. The hinge pins (34) include first (40) and second (41) hinge pin members, such as flat strips. The openings in the hinge eyes (28) are characterized by a narrow slotted portion (32) for restraining the first hinge pin member (40) against rotation within the slotted portion and a wider sector-shaped portion (33) that allows the second hinge pin member (41) to rotate relative to the first hinge pin member (40).

  • Patent number: 6974019
    Abstract: A conveying system including individually motorized transport elements or shoes that transport articles laterally across a conveyor. The motorized transport elements ride along tracks across the width of the conveyor. A motor drives each transport element across the conveyor. Local controllers in the transport elements or in the conveyor control the application of power to the motors and, thereby, the lateral positioning of the transport elements and the conveyed articles.

  • Patent number: 6854588
    Abstract: A trap door system for receiving a plurality of articles from a pick and place mechanism, moving those articles to the vicinity of an underlying tray on a conveyor, and dumping those articles on said conveyor in a pre-arranged layout, forming loaded trays, which loaded trays may then be positioned in a frame to form a cube for retort processing of the contents of the articles. The preferred embodiment of the invention contemplates a horizontally situated product gate for receiving a plurality of pouches which are received upon four side-by-side holding slots running the length of the pouch gate by a pick and place mechanism.
