  • Method and apparatus for separating lean meat from fat
    Patent number: 5215772
    Abstract: Meat having lean meat portions and fat meat portions is cut into relatively small segments of higher lean meat content and higher fat content. The segments are vibrated to prevent clinging between segments as they are conveyed to a segment spacing station where the segments are spaced from one another. The spaced segments are passed through the sensing zone of a sensor where an optical characteristic related to fat or lean meat content is sensed. Segments having a higher lean meat content are separated from segments of higher fat content in response to the sensed characteristic.
