Abstract
A method for separating fat from beef pieces containing fat. The method includes, with an apparatus, reducing the size of beef pieces containing fat when the fat is in a brittle condition into a mixture of particles that comprise predominantly fat and particles that comprise predominantly lean; and, with an apparatus, separating the fat particles from the lean particles based on color differences or size differences.
Claims13
A method for separating fat from beef pieces containing fat, comprising:
- chilling beef pieces containing fat and lean to a temperature at which fat will crumble and separate from the lean when a crushing force is applied;
- passing the chilled beef pieces within a gap created between a pair of spaced-apart opposed rollers, and with the rollers, reducing a size of beef pieces into a mixture of fat particles that comprise predominantly fat, and lean particles that comprise predominantly lean, wherein the fat particles are on average smaller than the lean particles;
- with an apparatus, separating the fat particles from the lean particles based on size differences between the fat particles compared to the lean particles;
- and
- emulsifying the fat particles into an emulsification of oily material and solids, pasteurizing the oily material and the solids, and centrifuging the emulsification to separate the solids from the oily material.
