Patent number: 11491491Abstract: A method to grind meat in a grinder, includes: providing the meat to the grinder via a hopper where the hopper includes a feeder worm for feeding the meat to a process unit. The process unit has a rotating processing worm and a cutting set. The rotating processing worm can receive the meat from the feeder worm and convey it to the cutting set, which grinds the meat. The method involves automatically adjusting the revolutions per minute of the rotating processing worm in response to a pressure creation in the process unit.Type: GrantFiled: July 6, 2018Date of Patent: November 8, 2022Assignee: MAREL A/SInventor: Christian Brochner Lind

Patent number: 10434483Abstract: High thermal transfer, hollow core extrusion screws (50, 52, 124, 126, 190) include elongated hollow core shafts (54, 128, 130, 192) equipped with helical fighting (56, 132, 134, 194) along the lengths thereof. The fighting (132, 134, 194) may also be of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). Structure (88, 90) is provided for delivery of heat exchange media (e.g., steam) into the hollow core shafts (54, 128, 130, 192) and the hollow fighting (132, 134, 194). The fighting (56, 132, 134, 194) also includes a forward, reverse pitch section (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to be used as complemental pairs as a part of twin screw processing devices (20), and are designed to impart high levels of thermal energy into materials being processed in the devices (20), without adding additional moisture.Type: GrantFiled: September 8, 2017Date of Patent: October 8, 2019Assignee: Wenger Manufacturing Inc.Inventors: LaVon Wenger, Allan C. Spellmeier, Philip B. Wiltz

Patent number: 9271508Abstract: Separation chambers, deboning machines, and methods of operating the same are provided. In one aspect, a separation chamber for a compression-type deboning machine includes a body defining an internal cavity therein having a frusto-conical shape. A central longitudinal axis of the body extends from a first opening of the cavity near a first end of the body to a second opening of the cavity near a second end of the body. The first opening is larger than the second opening. The separation chamber also includes a plurality of perforations defined through the body from an inner surface of the body to an outer surface of the body. Each perforation includes a perforation axis extending longitudinally through a center of the perforation. The perforation axes of the plurality of perforations are transverse to a radial axis extending perpendicular to the central longitudinal axis of the body.Type: GrantFiled: June 12, 2015Date of Patent: March 1, 2016Assignee: WEILER AND COMPANY, INC.Inventor: Eric A. Eisiminger

Patent number: 7905436Abstract: A pair of lugs in an opening of a grinding head of a grinding machine and a pair of corresponding openings in an orifice plate of a grinding machine are disclosed to properly orient the plate in the head during assembly. The lugs are preferably of two different sizes so that the orifice plate will only fit into the head in one orientation. The lugs may differ in size such that the person assembling the grinding machine will be able to visualize the correct orientation based on the size of the lugs and corresponding openings.Type: GrantFiled: October 19, 2006Date of Patent: March 15, 2011Assignee: Weiler and Company, Inc.Inventors: Nick J.

Patent number: 6357681Abstract: A cutter-separator. Product is fluidized under pressure, forced through the bore of a spring and thence through the gaps between the coils of the spring while in its extended condition. When the spring returns to its compressed, or relaxed, condition the product which has been forced through the coils is reduced in size (i.e., cut, partially cut, or mashed, as desired) by the spring. Contaminants which are too large to pass between the coils are ultimately carried to the end of the spring, downstream from the product flow, where they are discharged.Type: GrantFiled: July 18, 2000Date of Patent: March 19, 2002Assignee: The Board of Regents for Oklahoma State UniversityInventors: Timothy J.
