| 20120118175 | TREATMENT TO REDUCE MICROORGANISMS WITH CARBON DIOXIDE BY MULTIPLE PRESSURE OSCILLATIONS - 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. | 05-17-2012 |
| 20110171353 | DECONTAMINATION METHODS FOR MEAT USING CARBONIC ACID AT HIGH PRESSURES - 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. | 07-14-2011 |
| 20110008505 | METHODS FOR SEPARATING TALLOW FROM A SINGLE INGREDIENT STREAM OF BONELESS BEEF USING LIQUID CARBON DIOXIDE AND CARBONIC ACID - A method includes combining ground beef with liquid that comprises carbon dioxide. The ground beef and liquid are added to a vessel. The ground beef comprises relative light and heavy components. The components that are predominantly lean beef will settle to the bottom of the liquid, and components that are predominantly fat will rise to the surface of the liquid. The separated components comprising predominantly lean beef can be removed from the liquid as a reduced fat ground beef product. The method can be practiced with any material containing fat, including plants and animals. | 01-13-2011 |
| 20100112168 | HARVESTING OIL FROM FATTY MEAT MATERIALS TO PRODUCE LEAN MEAT PRODUCTS AND OIL FOR USE IN BIO-DIESEL PRODUCTION - A method and apparatus for separating lean meat and/or fat from lean meat-containing material, including combining a particulate material with fluid carbon dioxide. The material and fluid is introduced into a 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 bowl or an inclined vessel. Separation is achieved via gravity or the application of an artificial force field, such as centrifugal force, to separate particulates high in density from those low in density. | 05-06-2010 |

| 20090214733 | Separation of fatty materials to produce lean meat products - A method and apparatus for separating lean meat and/or fat from lean meat-containing material, including combining a particulate material with fluid carbon dioxide. The material and fluid is introduced into a 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 bowl or an inclined vessel.

| 20090214730 | Method of Separating Meat Components Via Centrifuge - 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. | 08-27-2009 |
| 20090074922 | METHOD AND APPARATUS FOR SANITIZING AND PROCESSING PERISHABLE GOODS IN ENCLOSED CONDUITS - The invention is directed to a method and apparatus for sanitizing perishable goods by mixing the goods with sanitizing liquor for a suitable period of time followed by separating the liquor and substantially neutralizing any residual sanitizing agent left in the goods. In one instance, the sanitizing agent includes ozone and water; therefore, separation of the ozonated water advantageously proceeds with a squeezing effect to more adequately remove the ozonated water from the goods. | 03-19-2009 |
