Gaming Chip Washing Machine
A machine for cleaning gaming chips or coins which includes means to convey individual coins or chips to a carrier wheel consisting of a vertically oriented disc having arranged about its periphery a plurality of coin or chip sized open recesses to receive individual coins or chips so that the coins or chips are supported on their edges and both faces of the coins or chips are exposed. The carrier wheel rotates through a washing station, a drying station arranged about said carrier wheel such that a drying air stream passes over and around said coins or chips in said carrier wheel. The coin or chip recesses in the carrier wheel are crenellated to allow washing fluid and the drying air stream to pass over the edges of the coins or chips. A total residence time for each chip that is sufficient to clean and dry the chips will lie in range of 10 to 20 seconds.
