In simple cases cleaning can also be effected
without circulation but
by pouring a cleaning
fluid solution into the system.
After some time of standing, flush the solution
with clean water.
If the heat exchanger is to be out of service
for a
long time, it is advisable to empty it, separate
the plates, and clean the unit. After cleaning,
lightly re-clamp the plate pack and cover it to
protect from dirt and UV light. Please refer to
section 7.0 on Storage.
Determination of correct CIP system
The heat exchanger must be opened for
inspection at regular intervals. This is necessary
especially during the initial start up period, until
experience has been gained on the
effectiveness of the cleaning regime. With these
inspections, it will gradually be possible to
determine circulation times, temperatures, and
chemical concentrations with great certainty.
Insufficient cleaning is most often due to:
•
Insufficient
circulation
rate.
•
Insufficient cleaning time or temperature.
•
Insufficient Concentration of the cleaning
agent.
•
Excessive periods of operation.
