Conveying device

摘要

Conveying device (1) comprises: two filling- (6) and two removal stations (7), through which a liquid food product (8), preferably milk, is transported respectively with different temperatures; two lines (9, 10), which are respectively pairwise connected to the filling- and removal stations; at least one pump, through which the food product is pumped in counter-flow through the two lines; and a heat transfer medium, through which the two lines are thermally coupled together. The heat transfer medium is formed as a solid body. Conveying device (1) comprises: two filling- (6) and two removal stations (7), through which a liquid food product (8), preferably milk, is transported respectively with different temperatures; two lines (9, 10), which are respectively pairwise connected to the filling- and removal stations; at least one pump, through which the food product is pumped in counter-flow through the two lines; and a heat transfer medium, through which the two lines are thermally coupled together. The heat transfer medium is formed as a solid body. The body completely or partially surrounds the two lines and is firmly connected together. An independent claim is also included for producing the line, preferably for the line, which comprises two chambers, comprising (a) unwinding a continuous plate-shaped initial workpiece, preferably made of metal, (b) bending the two outer edges of the initial workpiece in the opposite direction, (c) folding the two side portions of the initial workpiece at an angle of 90[deg] , which displaces the initial workpiece from the symmetrical axis and is parallel to this extending folding edge, (d) complete folding of the two side portions around the respective folding edge until the two outer edges lies on the respective opposite surface of the other side portions, and (e) welding or sealing the side portions on the joining edge.
