<p>A commercial dishwasher includes a first dishwashing unit and a dish-rinsing and sterilizing unit, each of these units having a passageway through which dish-carrying baskets are guided. The first unit has a water-receiving tank and power means for taking water from the tank and spraying it onto the dishes as the baskets pass through the first unit, the water returning to the first tank after washing the dishes. The first unit also has a plurality of removable screens placed on an inclined supporting ledge which extends downwardly at an inclined angle from the exit to the entrance thereof, the screens being positioned above the level of the water in the tank in the first unit. A hot rinse and sterilizing water are sprayed onto the dish-carrying basket as they pass through the rinsing and sterilizing unit. The hot water is delivered from the rinse and sterilizing unit to the exit end of the first unit for causing this heated used water to be directed over the inclined screens to flow over the screens for flushing any food particles on the screens towards the lower end, some of the water draining through the screens and dropping into the tank for raising the temperature of the water. An outlet pipe having its entrance at the lower end of the screens receives any food particles and water reaching the end of the screens so as to convey them away.</p> |
