ABSTRACT:
In a heating and mixing apparatus having an elongated cavity and a plurality of heating tubes extending along the length of the cavity, the improvement comprises at least one supporting member for the tubes and lying across the cavity along a plane approximately normal to the axis of the tubes and having a plurality of orifices through which the tubes extend. The support member has at least one opening therein to allow composition to pass therethrough, and preferably a plurality of the supports are spaced along the drum and disposed so that the openings of adjacent supports are not aligned with one another, thereby acting as temporary barriers for the composition as it is drawn gravitationally from one end of the apparatus to the other during heating and mixing process. In another embodiment, a portion of the support extends exteriorly of the drum and is exposed whereby the exposed portion may be agitated and which agitation is translated through the support to the tubes which causes vibration for assist in removing composition coated on the tubes.
