Abstract
Abstract Pieces of raw meat are placed into containers, are subjected to subcook heating and/or pressure, and are then promptly subjected to vacuum extraction, causing removal of melted fats and various enzymic liquescent constituents from the uncooked meat. Next the meat is seasoned and/or preserved in such containers. Steam injection is used to provide both heat and pressure. The steam is both introduced into and exhausted out from a container through a head assembly which covers the open top of the container.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
A mechanism for heating and pressurizing meat sections packed in an open top container, comprising: a injection head having an inlet and a foraminous outlet means placeable over the open top of the container; means for delivering a hot palatable fluid into said head, to flow therefrom through the outlet plate and into the meat; means for urging said open top container and said outlet plate relatively together, such that the outlet plate will serve to confine fluid and evolved vapors and gases from the meat in the container so that the pressure in said container is raised and the heating of the meat is done at superatmospheric pressure; and means for venting the fluid and any evolved gases or vapors from said container, through said head, while said outlet plate and the open top container are together, following stoppage of fluid delivery.
Claim 2
Dependent Claim
143 words
A mechanism for heating and pressurizing meat sections packed in an open top container, comprising: a injection head having an inlet and a foraminous outlet means placeable over the open top of the container; means for delivering a hot palatable fluid into said head, to flow therefrom through the outlet plate and into the meat; means for urging said open top container and said outlet plate relatively together, such that the outlet plate will serve to confine fluid and evolved vapors and gases from the meat in the container so that the pressure in said container is raised and the heating of the meat is done at superatmospheric pressure; and means for venting the fluid and any evolved gases or vapors from said container, through said head, while said outlet plate and the open top container are together, following stoppage of fluid delivery.
Claim 3
Dependent Claim
27 words
A mechanism according to claim 1, wherein said outlet plate further includes an annular seal in sealing engagement with the rim edge of the open top container.
Claim 4
Dependent Claim
39 words
A mechanism according to claim 1, wherein said outlet plate is formed to include a generally annular array of vent openings surrounding the said fluid emitting openings, which vent openings communicate the interior of said container with the atmosphere.
Claim 5
Dependent Claim
25 words
A mechanism according to claim 3, wherein the combined area of said vent openings is less than the combined area of said fluid emitting openings.
Claim 6
Dependent Claim
36 words
A mechanism according to claim 3, wherein an annular exhaust chamber surrounds said fluid chamber and said vent openings in the outlet plate discharge into said exhaust chamber, and said exhaust chamber opens to the atmosphere.
Claim 7
Dependent Claim
47 words
A mechanism according to claim 1, wherein said conduit means for delivering fluid into the fluid chamber includes valve means for selectively discontinuing the delivery of steam to the fluid chamber and venting said fluid chamber, the container and the contents of the container to the atmosphere.
Claim 8
Dependent Claim
27 words
A mechanism according to claim 6, wherein said outlet plate further includes an annular seal in sealing engagement with the rim edge of the open top container.
