Publication number: 20120282382Abstract: A centrifuge has an inner and an outer screw. The outer screw transfers material towards a cone-shaped section that leads to an outlet of the centrifuge. A mixture of meat components, liquid carbon dioxide, gas, and optionally water, is spun in the centrifuge. The dense components, such as lean meat, will accumulate away from the axis of rotation and be transferred by the outer screw towards the cone-shaped section. The less dense components, such as fat and adipose tissue, accumulate toward the center of rotation, and are transferred toward an outlet of the centrifuge via the inner screw. Gas accumulates in the proximity of the cone-shaped section and impedes liquid carbon dioxide from exiting with the dense components. The centrifuge is pressurized, which maintains carbon dioxide as a liquid.Type: ApplicationFiled: April 20, 2012Publication date: November 8, 2012Applicant: SAFEFRESH TECHNOLOGIES, LLCInventor: Anthony J.M.

Publication number: 20120276256Abstract: A method for decontaminating beef is disclosed. The method includes dicing beef into diced particles, chilling the diced particles into chilled particles, compressing and/or flexing the chilled particles to separate fat from the chilled particles to produce fat particles and lean particles, mixing the fat particles and lean particles with a fluid, wherein a density of the lean particles is initially less than a fluid density, treating the lean particles and fat particles with energy harmful to pathogens as the fluid and lean and fat particles pass through an energy-emitting device at least while the lean particles are less dense than the fluid, increasing the temperature of the lean particles to increase the density which causes the lean particles to sink in the fluid, and separating the lean particles from the fat particles.Type: ApplicationFiled: December 13, 2011Publication date: November 1, 2012Applicant: SAFEFRESH TECHNOLOGIES, LLCInventor: Anthony J.M.

Publication number: 20120231148Abstract: A method for the separation of fat from meat. The method includes providing individual pieces of meat containing lean and fat; subjecting the individual pieces of meat to cooling for a time sufficient to produce a difference in temperature between the fat and lean, wherein the fat is cooled such that the fat is friable and crumbles into finer particulates when subjected to a crushing force and the lean is cooled to a higher temperature than the fat and the lean is able to withstand a similar crushing force without substantially crumbling into smaller particulates; and with the fat and lean at the temperatures produced, subjecting the individual pieces of meat to a crushing force to separate particulates of fat from the individual pieces of meat.Type: ApplicationFiled: February 9, 2011Publication date: September 13, 2012Applicant: SafeFresh Technologies, LLCInventor: Anthony J.M.

Publication number: 20120225171Abstract: Disclosed is a method for producing treated meat having a predetermined proportion of water in a container. The method includes treating meat that has lost water content through evaporation with an agent capable of killing bacteria together with an amount of water, wherein the amount of water corresponds to the amount of water that is lost through evaporation. The method provides meat being treated with a bactericidal agent as well as also providing meat with the predetermined amount of water for packaging.Type: ApplicationFiled: September 2, 2011Publication date: September 6, 2012Applicant: SAFEFRESH TECHNOLOGIES, LLCInventor: Anthony J.M.

Publication number: 20120118175Abstract: Apparatus and methods to non-thermally treat goods for human consumption with carbon dioxide. Apparatus and methods rely on multiple pressure changes of carbon dioxide to affect one of three processes. A first process rapidly freezes and thaws water on the surface of the goods in rapid succession multiple times to detrimentally affect pathogens. A second process raises the pressure and temperature of carbon dioxide to supercritical conditions to detrimentally affect the lipids in the membranes of pathogens. A third process adjusts the pressure to form a dense carbon dioxide liquid with a low pH that may also detrimentally affect pathogens. All processes may be repeated or performed in succession, or in any order. Optionally, thereafter, the goods may be stored at low temperature in substantially 100% carbon dioxide for further pathogen reduction.Type: ApplicationFiled: January 23, 2012Publication date: May 17, 2012Applicant: SAFEFRESH TECHNOLOGIES, LLCInventor: Anthony J.M.

Publication number: 20110171353Abstract: A method for separating lean meat from lean meat-containing material includes combining a particulate material with fluid, subcritical carbon dioxide at a pH of about 7 or less and a pressure of about 600 psig. The material and fluid is introduced into the vessel and is separated into low density and high density fractions. The material from the low density fraction is removed via an outlet and has a higher percentage of fat than the material introduced into the vessel. The material from the high density fraction is removed via an outlet and has a higher percentage of lean meat than the material introduced into the vessel. The vessel can include a centrifuge or a vessel disposed toward the vertical having an upper and lower outlet, wherein the separation is achieved by the respective densities of the material, and the natural or an artificial gravity field.Type: ApplicationFiled: December 14, 2010Publication date: July 14, 2011Applicant: SAFEFRESH TECHNOLOGIES, LLCInventor: Anthony J.M.

Patent number: 7575770Abstract: A method is provided for tracking ground meat to the animal or animals from which the meat was harvested. The method includes obtaining animal portions that have information that is associated with the animal portions. The animal portions are loaded into a conduit or a vessel that includes a meat grinder. The amount of portions entering the conduit or the vessel are measured. The portions are ground into ground meat, and the amount of ground meat leaving the conduit is again measured. With the aid of a computer, when the amount of ground meat leaving the conduit corresponds to an amount of the portions that enter the conduit, the information that had been associated with the unground animal portions can also be associated with the ground meat.Type: GrantFiled: February 14, 2003Date of Patent: August 18, 2009Assignee: SafeFresh Technologies, LLCInventor: Anthony J.
