Abstract
Methods for separating lean and fat from beef or other meats and the separation apparatus are shown. The methods use microbiocidal fluids to reduce or eliminate possible sources of contamination.
Claims18
A method for separating fat from a lean meat-containing material, comprising:
- providing beef particles, wherein the beef particles include both lean and fat in varying proportions;
- reducing temperature of the beef particles by quick freezing, wherein a temperature after the tunnel for lean is higher than a temperature for fat;
- crushing the beef particles to result in fat particles that comprise predominantly fat and lean particles that comprise predominantly lean;
- after crushing, combining the fat particles and lean particles with a fluid in a vessel, wherein the density of the fluid is greater than the density of a majority of the fat particles and lower than the density of a majority of the lean particles, and the fluid contains nanobubbles.

A method for separating fat from a lean meat-containing material, comprising:
- mixing in a vortex vessel, fat particles and lean particles with a fluid in a vessel, wherein the density of the fluid is greater than the density of a majority of the fat particles and lower than the density of a majority of the lean particles, and the fluid contains nanobubbles;
- then, separating in a manifold vessel, the particles that sink in the fluid;
- then, separating in a floatation tank, the particles that float in the fluid;
- and
- then, collecting the fluid for recycling, wherein fluid with nanobubbles is also added to the manifold vessel and to the flotation tank.
