Patent number: 8911809Abstract: 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: GrantFiled: April 20, 2012Date of Patent: December 16, 2014Assignee: SafeFresh Technologies, LLCInventor: Anthony J. M.

Publication number: 20130337130Abstract: A method for separating fat from lean, while minimizing the loss of micronutrients from the lean, is disclosed. The method includes combining a mixture of fat particles that are a majority of fat, and lean particles that are a majority of lean, with a saturated aqueous fluid, wherein a density of the fluid is greater than a density of the fat particles, and wherein the fluid is saturated with one or more components found in beef prior to being combined with the beef particles. The method includes collecting the fat particles separate from the lean particles by causing the fat particles to rise in the fluid, and collecting the lean particles.
