Abstract
An apparatus for degreasing plastic automobile parts has a degreasing tank with a liquid degreasing agent reservoir in the bottom thereof and a degreasing vapor space thereabove, a heater in the reservoir for heating degreasing agent for vaporizing it, and a parts conveyor extending through the tank and having a downwardly inclined portion extending downwardly into the degreasing vapor space from one end to a nadir within the degreasing vapor space and an upwardly inclined portion extending out of the degreasing vapor space. Several cooling coils extend around the inside of the tank with an uppermost cooling coil at a level corresponding to the top of the degreasing vapor space and the remaining coils being spaced downwardly into said degreasing vapor space at intervals. The cooling coils are supplied with cooling medium under the control of a flow controller for causing cooling medium to flow through respective cooling coils the height of which in the degreasing vapor space is directly related to the speed of the conveyor, whereby the time a part being conveyed spends in degreasing vapor can be kept substantially constant regardless of the speed of the conveyor.
