This specification covers multiple tank, automatic rack less conveyor type, commercial dishwashing machines. These machines can be classified into two types: Type 1 machines shall be designed and supplied to accept the feeding of soiled tableware from the right side, when facing the front of the machine while Type II shall be designed and supplied to accept the feeding of soiled tableware from the left side, when facing the front of the machine. The dishwashing machines have three kinds of styles: Style 1 is a steam heated machine, with two classes namely Class A which uses injectors and Class B which uses heat exchange coils. Style 2 is an electrically heated dishwashing machine. Style 3 on the other hand is gas heated with two classes namely Class C which uses natural gas and Class D which uses LP gas. In addition, these dishwashing machines can be classified into three groups according to size and capacity: Group A, Group B, and Group C. Materials used in the manufacture of these machines shall consist of corrosion-resistant steel, corrosion resisting material, nickel-copper alloy and plastics. The dishwashing machine shall be complete so that when connected to the specified source of power, water supply, heating means (steam, electric, or gas), drainage, detergent, and rinse agent feeder as applicable, the unit can be used for its intended function. Dishwashers shall be rigid, quiet in operation, free from objectionable vibration, and so constructed as to prevent objectionable splashing of water to the outside of the machine. Operational test, leakage test, and performance profiles shall be done in order to determine the overall efficiency of the dishwashing machine.
