ABSTRACT:
A cleaning and drying apparatus comprises a vessel having a closed bottom and a side wall extending upwardly from the circumference of the bottom. The vessel has an inlet for introducing the discrete parts on the bottom of the vessel and an outlet formed in an upper end of the side wall for removing the parts out of the vessel. A spiral track is formed on the interior surface of the side wall to ascend therealong in a spiral manner about a vertical center axis of the vessel from the bottom to the outlet. A liquid line is connected to supply a cleaning liquid into the vessel. An level controller is provided to keep a level of the cleaning liquid in the vessel well below the outlet in such a manner as to divide the length of the spiral track into a drying zone immersed in the cleaning liquid and a drying zone disposed above the level. A vibrator is connected to apply vertical and circumferential vibrations which produces a driving force to feed the discrete parts upwardly along the spiral track to the outlet through the cleaning zone and continuously through the drying zone, during which the discrete parts are washed by the cleaning liquid while being fed through the cleaning zone. A dryer is adapted to direct a forced hot air flow along the drying zone to remove the cleaning liquid from the surfaces of the parts.
