Abstract
Abstract A mixture of blood and water is collected in catch basins on the slaughter floor of a slaughterhouse. A charge of blood and water is transferred from the catch basin to a closed container or gelatinizer where about 50 or 60 percent of the water content is vaporized through the injection of live steam into the gelatinizer and also by adding heat through steam coils in the gelatinizer. The live steam also agitates the charge. Thereafter the gelatinizer is closed and the gelatinated blood thus formed is removed by increasing the pressure in the vessel, forcing the gelatinated blood out a drain.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
32 words
The invention as defined in claim 1 with the additional limitations of f. transferring all vapors produced in the atmospheric gelatinizer to a condenser and g. condensing the vapors in the condenser.
Claim 2
Dependent Claim
22 words
The invention as defined in claim 1 with the additional limitations of f. said charge containing water in addition to the blood.
Claim 3
Dependent Claim
40 words
The invention as defined in claim 1 with the additional limitations of heating the charge by f. adding the live steam slowly at first and then g. increasing the rate of the live-steam injection as the charge increases in temperature.
Claim 4
Dependent Claim
32 words
The invention as defined in claim 4 with the additional limitations of h. transferring all vapors produced in the atmospheric gelatinizer to a condenser and j. condensing the vapors in the condenser.
Claim 5
Dependent Claim
56 words
ThE invention as defined in claim 1 wherein the gelatinous mass is removed by f. closing all vapor outlets of the gelatinizer, and g. opening bottom conduit valves of the gelatinizer, and h. injecting steam into the gelatinizer, thus j. increasing the pressure in the gelatinizer until the gelatinous mass is forced through the bottom conduit.
Claim 6
Dependent Claim
22 words
The invention as defined in claim 6 with the additional limitations of k. said charge containing water in addition to the blood.
Claim 7
Dependent Claim
32 words
The invention as defined in claim 6 with the additional limitations of k. transferring all vapors produced in the atmospheric gelatinizer to a condenser and m. condensing the vapors in the condenser.
Claim 8
Dependent Claim
39 words
The invention as defined in claim 6 with the additional limitations of when heating the charge k. adding the live steam slowly at first and then m. increasing the rate of live-steam injection as the charge increases in temperature.
Claim 9
Dependent Claim
32 words
The invention as defined in claim 9 with the additional limitation of n. transferring all vapors produced in the atmospheric container to a condenser and o. condensing the vapors in the condenser.
Claim 10
Dependent Claim
76 words
The invention as defined in claim 10 with the additional limitations of p. said charge containing water in addition to the blood and comprising about 80 percent blood and 20 percent water, q. said live steam being saturated steam at about 90 p.s.i.g., r. the gelatinous mass removed from the gelatinizer being neither dried nor completely cooked blood and s. said gelatinous mass being mixed with offal and bones and cooked therewith in an offal cooker.
