<p>A heat transfer apparatus for processing a liquid (II, 41) continuously has a positive mechanical drive for a set of vertical whip rods (14) each disposed in a vertical heat transfer tube (2). Each whip rod (14) is free-standing on its lower end and is sufficiently flexible to conform closely to the inner surface of the tube as it orbits. The orbital drive propels the whip rod directly through a pair of horizontal, vertically spaced plates (11, 12) that engage the rods (14) in loose openings (27, 27') that serve as fluid inlets from the drive plate. A motor (18) rotates a drive shaft (17) coupled to at least one eccentric crank (16, 16'). Each plate (11, 12) can be an opposed pair of plates (11, 11') with separate eccentric drives 180 degrees out of phase with one another for self-balancing.</p> |
