ABSTRACT:
A charge of distilland (33) is metered into a heated inclined trough (18) within a chamber (10). Vapors of distilland rise to a level (41) which is below the upper level (26) of the trough. The vapors spill over the sides (31 and 32) of the trough and fall to the lower section of the chamber where cooling coils (42) condense the vapors and the resultant distillate flows out an exit conduit (122). Residue materials are moved by a pusher (47) over the end (26) of the trough into a drain chute (51). During the return of the pusher, an air cylinder (103) is operated to lift the pusher from the bottom of the trough.
