Abstract
A conveyor dishwashing machine in which racks of dishes are conveyed from a loading surface through a hood which presents washing and rinsing zones and onto a discharge surface. In the washing zone, wash spray is applied to the dishes from a spray system which is easily removed for cleaning and easily replaced in the proper position. In the rinsing zone, a rinse curtain applies an initial rinse and creates a barrier against the wash spray. A final rinse of clean city water is applied subsequent to the rinse curtain. Automatic controls operate the machine with a minimum of human intervention.
