Patent number: 9538769Abstract: System and method for processing raw shrimp. A head-on shell-on shrimp is first back-slit to expose the vein. Next, the head and some or all of the vein is removed in a hydraulic deheader. The headless, back-slit shrimp is then peeled in a roller-type peeling machine to remove the shell and any residual vein and provide high-quality, peeled and deveined shrimp meat.Type: GrantFiled: January 4, 2016Date of Patent: January 10, 2017Assignee: Laitram, L.L.C.Inventors: Lars Vedsted, Bruce F. Taylor

Patent number: 8591296Abstract: Mollusc processing apparatus and related methods are disclosed. Molluscs are held in holders by one of their shells, illustratively the bottom shells, and are moved between a series of processing stations. At a shell cut station, an opening is cut into one or both of the shells of each mollusc. The next processing station includes a cutting blade to cut the adductor muscle and viscera of each mollusc away from its non-held shell, illustratively the top shell, and a shell detach mechanism to detach the non-held shell from the held shell. One or multiple air blasts are directed toward the viscera to loosen it from the held shell, and at a vacuum station the loosened viscera is pulled from the held shell. A second muscle cut station includes another cutting blade to cut the adductor muscle from the held shell.Type: GrantFiled: October 27, 2010Date of Patent: November 26, 2013Assignee: Clearwater Seafoods Limited PartnershipInventors: Gleb Sekretta, Ben Garvey, Timothy Andrew Burke, Bruce Allan Stover, Andrew Neville Cormack, Gerard Murray Prinsen, Angus McLarty, Jacob MacKinnon, Nathaniel Bruce Tynes, Louis-Phillipe Frederick Manuge, Tracy Rose, David Rose, Lee Babin

Patent number: 6537601Abstract: The invention relates to a process for eliminating pathogenic organisms and other bacteria from raw food products, such as raw shellfish, whereby the molluscan shellfish is exposed to hydrostatic pressure of relatively high value, for example between 10,000 p.s.i. to 60,000 p.s.i. for 1-15 minutes. The process is conducted at elevated temperatures, in the range of between 50 and 130 degrees Fahrenheit, leaving the raw shellfish substantially unaffected, in its desired raw state, such that the pathogenic organisms are destroyed, while sensory characteristics of the raw shellfish remain high. The same process can be used for shucking bivalve mollusks without any mechanical force, with the pressure ranging from 10,000 p.s.i. to 60,000 p.s.i. Taste of raw seafood is enhanced by adding flavor enhancing agents to the pressure vessel before application of pressure.Type: GrantFiled: November 27, 2000Date of Patent: March 25, 2003Assignee: Innovatit Seafood Systems, LLCInventor: Ernest A. Voisin

Patent number: 6426103Abstract: The invention relates to a process for eliminating pathogenic organisms and other bacteria from raw food products, such as raw shellfish, whereby the molluscan shellfish is exposed to hydrostatic pressure of relatively high value, for example between 20,000 p.s.i. to 150,000 p.s.i. for 1-15 minutes. The process is conducted at minimal elevated temperatures, in the range of above ambient temperature to 150° F., leaving the raw shellfish substantially unaffected, in its desired raw state, such that the pathogenic organisms are destroyed, while sensory characteristics of the raw shellfish remain high. The same process can be used for shucking bivalve mollusks without any mechanical force, with the pressure ranging from 10,000 p.s.i. to 100,000 p.s.i. Taste of raw seafood is enhanced by adding flavor enhancing agents to the pressure vessel before application of pressure.Type: GrantFiled: December 15, 2000Date of Patent: July 30, 2002Assignee: Innovatit Seafood Systems LLCInventor: Ernest A.

Patent number: 6110032Abstract: A shellfish processing apparatus (10) particularly intended for Scallop Processing, in which a gripped shellfish is partially opened initially by manipulator means (12) so as to enable meat to be removed from one shell half at a station (22), and then opened fully at a station (24) for evisceration at a station (28) removal of meat from the remaining shell half at a station (32). The evisceration means (113) preferably includes a backing plate (122) which serves to concentrate water around the shell half being eviscerated and to hold the adductor muscle in place.Type: GrantFiled: May 21, 1999Date of Patent: August 29, 2000Assignee: OCTA Technologies Pty Ltd.Inventor: Dennis Charles Earnshaw

Patent number: 5112269Abstract: An apparatus for shelling shellfish such as shrimps consists of a dosing chamber (3) and a heat treatment chamber (5) separated by a slide valve (11) and sealed by cylindrical membrane valves (7, 9). From a funnel (31) the shellfish fall down into the dosing chamber (3) whose valve (7) is closed. The slide valve (11) is opened and a portion of animals fall down into the heat treatment chamber (5), whose bottom is closed by another membrane valve (9). The slide valve (11) is closed and steam at high pressure and temperature is induced into the heat treatment chamber (5). The pressure is removed from the membrane valve (9) after which the standing overpressure in the chamber (5) blows the shellfish out of the discharge opening (19) towards a rebound plate (35). Hereby the meat and shells of the shellfish are separated.Type: GrantFiled: August 9, 1990Date of Patent: May 12, 1992Inventors: Frede H. Petersen, deceased, Kaj A. Sorensen
