Abstract
A meat processor having a drum which rotates about an axis perpendicular to its longitudinal axis and shakes while keeping the meat being processed in the drum refrigerated and under a vacuum.
Claims14
A meat processor comprising
- a drum relatively smooth walled interior cavity having an internal vertical cross-section disposed parallel to the longitudinal axis of said drum which, when said drum is rotated about an axis perpendicular to the plane of said cross-section, causes the meat disposed in said drum to tumble and slide from end to end in said drum, and
- means for shaking said drum up and down with a preferred variable rate in the plane of said cross-section with a preferred predeterminable variable positive vertical displacement of the drum irrespective of the rate of rotation of the drum or the weight of meat being processed in the drum.
A meat processor comprising
- a drum with a relatively smooth walled interior cavity having a substantially rectangular vertical cross-section disposed parallel to the longitudinal axis of said drum, said drum being arranged to rotate about a horizontal axis perpendicular to the plane of its rectangular cross-section at a variable rate between one (1) nd twenty-five (25) rpm,
- means for simultaneously shaking said drum up and down with variable positive vertical displacement in the plane of said rectangular cross-section at a rate between twenty-five (25) and five hundred (500) cycles per minute, and
- a frame supporting said drum, said frame being arranged so that at least a portion of it can be reciprocated up and down to effect the shaking of said drum with the remaining portion of said frame secured to the reciprocating portion thereof with a hinge connection.
A meat procesor comprising
- a drum having a substantially cylindrical interior cavity, said drum being mounted on a frame to rotate end for end about a horizontal axis perpendicular to the longitudinal axis of said cavity, said frame being arranged to pivot at one end so that the other end can be moved generally up and down a predetermined variable distance to permit the drum to be vertically displaced,
- means attached to said frame for rotating said drum at a variable rate between one (1) and twenty-five (25) revolutions per minute,
- means for reciprocating the movable end of said frame up and down through said predetermined distance with positive displacement at a variable rate between twenty-five (25) and five hundred (500) cycles per minute, and
- means for evacuating the unoccupied interior cavity of said drum after it has been filled to its operating volume with meat to be processed.

A meat processor comprising
- a frame pivoted at one end to permit at least partial rotation of said frame about a horizontal axis and to permit the remainder of said frame to be cycled up and down,
- a motor driven adjustable throw crank shaft connected to a movable portion of said frame and arranged to cycle it up and down a predetermined distance at a variable rate between twenty-five (25) and five hundred (500) cycles per minute,
- spring means and variable pressure airbags mounted under the movable end of the frame to assist the up and down cycling of said frame,
- a drum having substantially cyclindrical interior cavity, said drum being mounted on said frame and arranged to rotate about a horizontonal axis perpendicular to the longitudinal axis of said cavity,
- a motor mounted on said frame arranged to rotate said drum at a variable rate between one (1) and twenty-five (25) revolutions per minute,
- an air-tight cover for said drum,
- a vacuum connection mounted on said drum to permit a vacuum to be pulled on said cavity after it has been filled to its operating volume with meat to be processed to permit evacuation of air from the unfilled portions of said cavity,
- refrigerating coils secured to said drum, said coils being fed through rotatable connections integral to rotatable journals mounted on said frame supporting said drum, and
- a removable cylindrical insert for the cavity of said drum, said insert including means for working said meat to increase the rate of myosin extraction therefrom.
