Abstract
Abstract An apparatus for continuously making beer wort from dried malt has a malt soaking unit and a malt crusher which is adapted to receive the soaked malt from the unit and has at least two smooth-surface cooperating rolls and drive means for driving them at differential velocities. A conduit system has a plurality of upright heatable conduit sections and serves for heating a mash which is produced after the malt has been treated in the crusher, and a clarifying unit is provided for clarifying the mash having been heated previously.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
96 words
In an apparatus for continuously making beer wort from dried malt, a combination comprising first means comprising a malt soaking unit and a malt crusher adapted to receive soaked malt from said unit, said crusher comprising at least two smoothsurfaced cooperating rolls and drive means for driving the same at differential velocity; second means, comprising a conduit system having a plurality of upright heatable conduit sections, for heating a mash produced after treatment of the malt by said first means; and third means for clarifying the mash after treatment of the same by said second means.
Claim 2
Dependent Claim
96 words
In an apparatus for continuously making beer wort from dried malt, a combination comprising first means comprising a malt soaking unit and a malt crusher adapted to receive soaked malt from said unit, said crusher comprising at least two smoothsurfaced cooperating rolls and drive means for driving the same at differential velocity; second means, comprising a conduit system having a plurality of upright heatable conduit sections, for heating a mash produced after treatment of the malt by said first means; and third means for clarifying the mash after treatment of the same by said second means.
Claim 3
Dependent Claim
27 words
A combination as defined in claim 1, wherein said drive means comprises a drive operative for rotating said rollers at a velocity differential of between substantially 5-10percent.
Claim 4
Dependent Claim
44 words
A combination as defined in claim 1, wherein said conduit system comprises a main conduit having a plurality of conduit portions, and a plurality of secondary conduits each of which is connected in parallel with one of said conduit portions of said main conduit.
Claim 5
Dependent Claim
36 words
A combination as defined in claim 1, wherein said conduit system comprises a plurality of conduit portions, bypass conduits bridging some of said conduit portions, and valve means for selectively blocking and unblocking said bypass conduits.
Claim 6
Dependent Claim
65 words
A combination as defined in claim 1, wherein said third means comprises a circular rotor mounted for rotation about an upright axis and having a plurality of downwardly open sector-shaped chambers for the mash, and a stationary wall member directly beneath said rotor and provided with a plurality of sieve slots concentric to said axis for passage of mash which issues from the respective chambers.
Claim 7
Dependent Claim
42 words
A combination as defined in claim 5, wherein said wall member has a sector-shaped opening adapted to register with each of said chambers once during each revolution of said rotor, for discharge of solid matter from the respective chamber through said opening.
Claim 8
Dependent Claim
43 words
A combination as defined in claim 5, wherein said conduit means has an outlet arranged above said rotor, and wherein said chambers have upper open ends into which said outlet discharges mash when the respective upper open ends are located beneath said outlet.
