Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
108 words
A heat exchange device for a tank having an agitator and serving as a fermentor, said device comprising a plurality of pipe blocks of the vertical trombone type, each block consisting of a plurality of vertical straight heat exchange fluid pipes disposed in staggered relationship about a line extending radially within the tank, said agitator means creating flow substantially normal to the radially extending line so that fluid is in equivalent contact with the fluid pipes, and said fluid pipes being connected to one another by U-shaped bent pipes and connected to an inner wall surface of the tank, said pipe blocks being disposed radially in the tank.
Claim 2
Dependent Claim
108 words
A heat exchange device for a tank having an agitator and serving as a fermentor, said device comprising a plurality of pipe blocks of the vertical trombone type, each block consisting of a plurality of vertical straight heat exchange fluid pipes disposed in staggered relationship about a line extending radially within the tank, said agitator means creating flow substantially normal to the radially extending line so that fluid is in equivalent contact with the fluid pipes, and said fluid pipes being connected to one another by U-shaped bent pipes and connected to an inner wall surface of the tank, said pipe blocks being disposed radially in the tank.
Claim 3
Dependent Claim
73 words
A heat exchange device in a tank provided with agitator means, said device comprising: at least one block of plural generally vertical heat exchange fluid conduit means disposed radially within said tank, said conduit means being disposed in a staggered manner about a line extending radially within the tank said agitator means creating flow substantially normal to the radially extending line so that said fluid is in equivalent contact with the conduit means.
Claim 4
Dependent Claim
73 words
A heat exchange device in a tank provided with agitator means, said device comprising: at least one block of plural generally vertical heat exchange fluid conduit means disposed radially within said tank, said conduit means being disposed in a staggered manner about a line extending radially within the tank said agitator means creating flow substantially normal to the radially extending line so that said fluid is in equivalent contact with the conduit means.
Claim 5
Dependent Claim
29 words
