6.1 Cleaning – Product side
Immediately after a production cycle, the product side is normally cleaned
through the circulation of acid and/or lye as a built-in sequence in the
production cycle.
NOTE
After the first test run of the product, the plate heat exchanger should be
cleaned following a cleaning program applicable to the product in
question. The plate heat exchanger should then be opened, see Section
Opening on page 55, and the plate surfaces carefully inspected. The
cleaning results should be checked at regular intervals.
WARNING Risk of personal injury.
Use proper protective equipment when using the cleaning agents. See
Section
Personal protective equipment in Chapter Safety .
WARNING
Corrosive cleaning liquids. Can cause serious injuries to skin and eyes.
Use proper protective equipment. See Section Personal protective
equipment in Chapter Safety
Sterilisation is performed immediately before starting the next production
cycle. See Section
Sterilisation on page 50
Flow rates
The flow rate during the cleaning of the product side should always be at least
the same as the production’s flow rate. An increased flow rate may be required
in some cases, for example in milk sterilisation and the processing of viscous
liquids or liquids containing particles.
Recommended limits for cleaning solutions:
• 5% by volume AlfaCaus at max. 70°C
• 0.5% by weight acid solution at max. 70°C
For detailed information regarding cleaning and sterilisation contact an Alfa
Laval representative.

The methods of sterilisation below are recommendations. Instructions for
