5.2.2 Alkaline foam cleaning
Alkaline foam cleaning ensures that fat, proteins etc. will be degraded chemically.
• Foam the machine from top to bottom. Foaming may be performed while
the machine is running slowly, provided sufficient distance is kept to the moving
parts of the machine. Mind the other machines.
• After foam cleaning remove the dirt and foam residue thoroughly by means of the
high-pressure water jet.
For alkaline foam cleaning use the following equipment:
• A fixed piping system for foam delivery.
• A large spray-nozzle of the flat-jet type, through which the foam can be distributed
equally along the surface.
• The alkaline foam detergent used should not affect the materials which it will
contact. Consult your detergent supplier to know which detergents will fulfil these
specific requirements and which cleaning directions to follow.
Obey these instructions. Incorrect application may be dangerous
Please avoid:
• A too high concentration.
• A too long contact
• Not rinsing
• Mixing with other products
It is advisable not to use a combination of detergents and disinfectants ('detergent
sanitizers"). This leaves the machine too dirty to be disinfected effectively.
A combination of these two methods is of no use at all.
