Abstract
Abstract An apparatus for removing air from meat emulsions or the like wherein the flow of the product via a conduit to the vacuum chamber of the apparatus is regulated by a valve located essentially inside the chamber. The valve, due to its location, is easily removable for conduit clearing and clean up purposes, besides providing improved flow control and therefore, vacuumizing of the product.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
In a vacuumizing apparatus which is adapted to remove air from a meat emulsion, of the type comprising: a hopper for storing the meat emulsion, a vacuum chamber adapted to be connected to a source of vacuum, a conduit connecting said chamber and hopper for the passage therethrough of the meat, a pumping chamber connected to said vacuum chamber, a piston adapted to be connected to a source of power and mounted for reciprocation in said pumping chamber, a stuffer in communication with said pumping chamber with a check valve assembly therebetween, and means for moving the meat pumped into said stuffer by said pump piston out of said stuffEr, wherein the improvement comprises: a valve movably mounted in said vacuum chamber in communication with said conduit to control the flow of meat through said conduit into said vacuum chamber and means for actuating said valve.
Claim 2
Dependent Claim
146 words
In a vacuumizing apparatus which is adapted to remove air from a meat emulsion, of the type comprising: a hopper for storing the meat emulsion, a vacuum chamber adapted to be connected to a source of vacuum, a conduit connecting said chamber and hopper for the passage therethrough of the meat, a pumping chamber connected to said vacuum chamber, a piston adapted to be connected to a source of power and mounted for reciprocation in said pumping chamber, a stuffer in communication with said pumping chamber with a check valve assembly therebetween, and means for moving the meat pumped into said stuffer by said pump piston out of said stuffEr, wherein the improvement comprises: a valve movably mounted in said vacuum chamber in communication with said conduit to control the flow of meat through said conduit into said vacuum chamber and means for actuating said valve.
Claim 3
Dependent Claim
64 words
The apparatus of claim 1 in which said vacuum chamber has a valve body portion with said conduit connected thereto, and said valve is in the form of a sleeve having a closed end located in said body, said valve having a side port movable with said valve in and out of said valve body to control the flow of meat through said port.
Claim 4
Dependent Claim
19 words
The apparatus of claim 2 in which said sleeve side port is located in the bottom of said sleeve.
Claim 5
Dependent Claim
19 words
The apparatus of claim 3 in which said side port covers less than 180* of circumference of said sleeve.
Claim 6
Dependent Claim
56 words
The apparatus of claim 4 in which a portion of said closed end of said sleeve extends outwardly of said sleeve on opposing sides thereof and further comprising a pair of rods which straddle said sleeve and are removably connected to said portion and extend outwardly through vacuum chamber openings for movement by said actuating means.
Claim 7
Dependent Claim
30 words
The apparatus of claim 5 further comprising means for sealing said rods in said chamber openings, and further comprising carriage means removably connected to said rods outside said vacuum chamber.
Claim 8
Dependent Claim
32 words
The apparatus of claim 6 in which said actuating means is a pair of cylinders connected to said carriage and said chamber and adapted to be connected to a source of power.
Claim 9
Dependent Claim
31 words
The apparatus of claim 7 further comprising adjusting means mounted on said carriage for controlling the position of said port in relation to said valve body to regulate the flow therethrough.
Claim 10
Dependent Claim
37 words
The apparatus of claim 8 in which said sleeve end has handle means whereby said sleeve can be moved from said valve body into said vacuum chamber upon disconnection of said sleeve end portion from said rods.
Claim 11
Dependent Claim
24 words
The apparatus of claim 9 in which said vacuum chamber has a transparent top for observing the flow of meat emulsion throught said valve.
