The machine consists of the following zones:
• wash zone
• rinse zone
and can be integrated with the following units:
•prewash zone
B2.1 Wash zone
Water with the addition of detergent is sprayed on the dishes in the wash zone through an upper and lower wash arm
system. The purpose of this function is to remove all residuals of food from the dishes. Washing is carried out with water
circulating at a temperature of 71-78 °C / 160-172 °F.
B2.2 Rinse zone
Water with the addition of rinse aid is sprayed on the dishes in the rinse zone through a system of arms equipped with
special nozzles. The purpose of this function is to remove all residuals of detergent deriving from the previous wash
phase.
Rinsing is carried out with clean water coming from the water system, heated to a max. temperature of 82-90 °C / 180-
194°F.
The high temperature ensures satisfactory drying and careful neutralization of bacteria. The addition of rinse aid allows
the water to easily run off the dishes, thus favouring the drying process.
B2.3 Prewash zone
Water is sprayed on the dishes in the prewash zone through an upper and lower prewash arm system. The purpose of
this function is to remove the larger food residuals, preparing the dishes for the subsequent wash phase.
Prewash is carried out with water circulating at a max. temperature of 40°C / 104°F in order to prevent food residuals (in
particular proteins) from sticking to the dishes.

In rack-type dishwashers the various zones just described are thus applied to the various previously defined configura-
tions.
