A cryogenic deflashing apparatus is provided specifically adapted to remove residual flash from relatively large molded articles in a continuous high production deflashing operation. The apparatus incorporates a modular deflashing housing wherein entry, pre-freezing, blasting, and exit of multiple articles is accomplished simultaneously in discrete serially aligned operational compartments. A novel article conveyor transport mechanism is additionally provided which permits the transport speed of the articles through the various compartments to be independently varied during operation to maximize production efficiency.
