7.1 Cleaning and washing
Before washing the machine, make sure that the
main switch is turned to OFF.
The procedure for washing the production line is as
follows:
a- Prewash with hot water (50ºC).
b- Detergent wash. Use a foaming alkaline
detergent or gel detergent which is a powerful
fat emulsifier in a concentration of 2% to 10%,
depending on how dirty the machine is and on
the hardness of the water supply.
c- Rinse with water. Wait 10 minutes and then rinse
thoroughly to remove the dirt emulsified by the
detergent.
d- Descaling wash. Use an acidic descaler with low
viscosity containing a mixture of wetting agents
and emulsifiers in a concentration of 2% to 3%.
It should remain in contact for at least 15 – 20
minutes.
e- Rinse with water.
f- Disinfectant wash. Use an appropriate
disinfectant diluted in water, in a concentration
of 1 – 1.2%. It should remain in contact for at
least 15 – 20 minutes.
