Every commercial warewasher has to use some form of detergent to make sure that all ware comes out clean at the end of the washing process. What are the latest developments in detergents and dispensing to ensure efficient cleaning.

The very raison d'etre of a commercial warewasher is that it can clean all cooking - and tableware, and to do this, it obviously has to use detergent. However, the way detergent is dispensed does vary from manufacturer to manufacturer, so what do distributors need to know about the options on offer?

Over at DC Products, director, Bob Wood, feels: "For dishwasher detergents and rinse aids to be effective and to counter corrosion and the formation of deposits of starch, lime and protein, they must be introduced into the dishwasher at the correct time and in the correct quantity. To be effective this process should be automatic".

All DC undercounter warewashers and passthrough dishwashers are fitted with automatic detergent and rinse aid dosing systems which operate on a time-release basis. DC rack conveyors (and passthrough dishwashers - optional) have wallmounted chemical auto-dosing pumps. They have a PCB (power circuit board) which the engineer will use to select one of three detergent and rinse aid dispensing options.

Wood encourages dealers to "look for machines with smaller wash tanks and which have automatic dosing pump options. Choose those that are more efficient in terms of reduced water usage per cycle and explain to end users the functions of detergents, rinse aid and specialist chemicals along with the serious consequences of under and over-dosing".
