Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
49 words
Afermentation reactor for zootechnic liquid 35 material, the fermentation reactor comprising a vessel, a substantially vertical tube within the vessel, the tube being provided with slots distributed along its length, and an Archimedian screw housed in the tube and rotatable about its own axis by a drive 40 mechanism.
Claim 2
Dependent Claim
49 words
Afermentation reactor for zootechnic liquid 35 material, the fermentation reactor comprising a vessel, a substantially vertical tube within the vessel, the tube being provided with slots distributed along its length, and an Archimedian screw housed in the tube and rotatable about its own axis by a drive 40 mechanism.
Claim 3
Dependent Claim
35 words
Afermentation reactor according to claim 1 in which the Archimedian screw has lower and upper sections and the helix pitch in the lower section is smaller than the helix pitch in the upper section. 45
Claim 4
Dependent Claim
31 words
Afermentation reactor according to claim 1 in which the Archimedian screw has lower and upper sections and there are more helix starts in the lower section than in the upper section.
Claim 5
Dependent Claim
33 words
Afermentation reactor according to any pre-50 ceding claim in which the Archimedian screw has a lowermost section having radially projecting blades inclined at a few degrees to the axis of the Archimedian screw.
Claim 6
Dependent Claim
30 words
Afermentation reactor according to any pre-55 ceding claim in which the slots in the tube are distributed in groups spaced apart from one another along the axis of the tube.
Claim 7
Dependent Claim
25 words
Afermentation reactor according to claim 5 in which there are four groups of slots, each group 60 comprising three identical slots equispaced around the tube.
Claim 8
Dependent Claim
34 words
Afermentation reactor according to claim 5 or claim 6 in which the distance separating each group of slots from the next adjacent group of slots is 1/4 of 65 the length of the tube.
