ABSTRACT:
A heat transfer roll has first and second disc-shaped outer end sections each having a centrally located tubular shaft. An inner tubular body is fitted over the two outer end sections, and a plurality of spiral ribs extend from the first end to the second end around the inner tubular body, and an outer tubular shell is fitted over the spiral ribs to form a plurality of spiral channels. Each of the end sections have one or more passageways therein which are in communication with the bore through the tubular shaft and the spiral channels. One of the outer end sections is adapted to receive a plurality of removable plugs, such that each removable plug when inserted will block the flow of liquid to one of the spiral channels. To clean such a heat transfer roll, all but one channel may be closed such that the remaining open channel may be cleaned.
