Abstract
This invention concerns a machine for the drying, polishing and burnishing cutlery and other metal tableware. It consists of a tank suspended upon a base and moved by a vibrating device, having a treatment channel (15) designed to receive a drying material and the articles for treatment. The treatment channel (15) rises in a spiral from an entrance chute at the loading mouth to an exit passage or chute for the articles and has, in a transverse cross-section, a U-shaped bottom (22) defined by a substantially cylindrical concave surface and, lengthways, by a series of straight segments (23) which alternate with and are joined to curved segments (24), without sharp edges or corners. Ideally, the channel has a steeper gradient towards the exit.
