2 DESCRIPTION OF STANDARD CYCLE
The standard cycle comprises:
• one or more pre-rinses
• one wash cycle
• one cold or lukewarm rinse
• one hot rinse
• one drying cycle (see attached line drawing)
The pre-rinses remove larger food particles and are run with 5 grammes of
detergent. In cycles such as the intense wash, the pre-rinse will be heated.
The wash cycle is the stage in which food particles are removed through the
action of the enzymatic detergent and temperatures reached.
The rinse cycles eliminate any remaining dirt from plates as well as
preparing them for drying by dispensing the rinse aid and taking the
temperature over 60°C.
1. Chart 1 shows the temperatures reached throughout the cycle and when
the heating element switches on and off to reach the required temperature.
You will see the cold pre-rinse, wash with gradually increasing temperature
and hot-rinse stages.
