Abstract
The present disclosure relates to a dishmachine that includes at least two tanks and methods of using the tanks to isolate, substantially isolate, or incrementally isolate different chemistries from each other during a cycle. The disclosed dishmachine design and method allows for the use of two different, and potentially incompatible, reactive, or offsetting chemistries to be used in the same dishmachine cycle.
Claims23
A dishmachine comprising:
- (A) a wash chamber having wash arms mounted therein;
- (B) a first tank;
- (C) a first pump operatively connected to the first tank and the wash chamber through a first conduit, wherein the first tank is in fluid communication with the wash arms;
- (D) a second tank;
- (E) a second pump operatively connected to the second tank and the wash chamber through a second conduit, wherein the second tank is in fluid communication with the wash arms;
- (F) a diverter plate selectively movable between a first position and a second position wherein the first position causes the diverter plate to be in fluid communication with the first tank and the second position causes the diverter plate to be in fluid communication with the second tank;
- (G) a gutter plate located above the diverter plate;
- and
- (H) a removable strainer located on top of the gutter plate.
