Abstract
Abstract A series of rotatably arranged perforated sheet metal drums are proposed through which sauerkraut may be traversed in either a water or heated brine solution. A control system for heated brine is arranged so that the brine emitted from a heat exchanger passes through partitioned chambers in which each drum is arranged to rotate, the last of this series of drums adapted to receive the hottest solution and the brine thence traveling to the next adjacent drum in succession.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
An apparatus for blanching sauerkraut comprising, a rotatable perforated sheet metal drum unit having an inlet zone and an outlet zone for passage of sauerkraut therethrough and a receptacle for holding a supply of brine through which the sauerkraut is arranged to travel, further wherein a series of drums comprising said unit are arranged seriatim with the sauerkraut being advanced through each of said drums from said inlet zone to said outlet zone, said receptacle being positioned to provide spaced areas for said brine and within which each said drum unit can rotate, heating apparatus for said brine and flow control means to supply heated brine from said drum in said oulet zone to the next adjacent drum in succession.
Claim 2
Independent Claim
120 words
An apparatus for blanching sauerkraut comprising, a rotatable perforated sheet metal drum unit having an inlet zone and an outlet zone for passage of sauerkraut therethrough and a receptacle for holding a supply of brine through which the sauerkraut is arranged to travel, further wherein a series of drums comprising said unit are arranged seriatim with the sauerkraut being advanced through each of said drums from said inlet zone to said outlet zone, said receptacle being positioned to provide spaced areas for said brine and within which each said drum unit can rotate, heating apparatus for said brine and flow control means to supply heated brine from said drum in said oulet zone to the next adjacent drum in succession.
Claim 3
Dependent Claim
38 words
An apparatus in accordance with claim 1, further wherein said drum unit comprises at least three drum members, each of said drum members having cylindrical inlet and outlet openings of a lesser circumferential area than said drum members.
Claim 4
Dependent Claim
26 words
An apparatus in accordance with claim 1, further wherein said supply of brine is fed to said drum member through guideway means disposed above said drum.
Claim 5
Dependent Claim
60 words
An apparatus in accordance with claim 1, further wherein said brine which exits from said drum member disposed adjacent to said inlet zone is supplied through a line to an equalization container, from which said brine proceeds through said line to said heating apparatus which thereafter delivers said heated brine into said drum member disposed adjacent to said outlet zone.
Claim 6
Dependent Claim
81 words
An apparatus in accordance with claim 4, further wherein a temperature probe is provided in said line for said heated brine delivered by said heating apparatus, said heating apparatus further including a heat exchanger, and further that a flowthrough rate meter which is adapted to emit signals is disposed in said line, that said signals emitted by said flowthrough rate meter proceed to a closed-loop control apparatus, which is adapted to control a supply of hot steam to said heat exchanger.
