Patent ID: 7255223

Claim:
Conveying device for transporting a conveyable product, comprising: an essentially cylindrical axially extending chamber, at least one axially extending shaft disposed in said chamber which extends along the axis of the chamber, said shaft having a plurality of first conveying elements axially spaced from one another to form a discontinuous web, the conveying elements being axially spaced discrete paddles or beaters; said first conveying elements transporting the product in an axially extending product-conveying direction, said first conveying elements extending radially from the shaft and being connected with the shaft in each case at a connecting site on the surface of the shaft, the individual connecting sites being disposed along a helical line at the surface of the shaft, the plurality of first conveying elements forming a first flight corresponding to the helical line which extends helically about the surface of the shaft, the first flight disposed along a plurality of revolutions about said shaft at a first helical pitch, the first flight being divided into at least two axially spaced partial flights at least in axially spaced partial regions of said shaft, each partial flight including a plurality of said axially spaced discrete paddles or beaters, further elements in a further element section, the further element section disposed along at least one revolution about said shaft at a second helical pitch that is smaller than the first helical pitch, the number of further elements disposed along said at least one revolution about said shaft in said further element section being greater than the number of elements disposed along each revolution about said shaft in said first flight, the further element section axially protruding into the first flight disposed at least in partial regions of the first flight, the further elements in the further element section forming at least one further, discontinuous web, which extends along and within the first flight, and the number of further discontinuous webs and, with that, the number of partial flights increasing in the product-conveying direction.
