13 General information on washing dishes in a machine

There are a number of basic principles which apply to machine-washing dishes
irrespective of the machine manufacturer, type, model, design and construction of the
dish-washer.

13.1 Washing and rinsing zones

From the point of view of washing techniques, two processes must be distinguished from
each other and which are carried out in different locations in a conveyor machine:
 Cleaning the dishes in the main washing zone
 Rinsing the dishes in the clean water rinse zone.
Main washing zone
In the main wash zone (HWZ) the food particles etc. adhering to the dishes should be
swilled off and dispersed from the plates and taken into the wash water. The wash water
is sucked from the wash tank by means of a circulating pump and sprayed onto the
dishes through a system of jets. The wash water flows back into the wash tank through a
screen which retains the largest food particles and is then re-circulated by the pump. The
wash water is therefore in a circulatory system.
The detergent is introduced into the wash tank (using a special dosing unit).
The purpose of the detergent is to remove the particles of grease and dirt adhering to the
dishes and to hold them in suspension (to bind them) in such a way that they cannot re-
contaminate the dishes (only suitable machine detergents must be used for this purpose).
The concentration of detergent necessary in the wash tank depends on the degree of
soiling and the water quality.
Depending on the chemical supplier, wash water temperatures of between 50 and 60° C
are recommended to allow the detergent to develop its washing properties to the full.
