4.5 SUCCESSIVE CYCLES
Generally, the most efficient CIPs comprise 5 stages :
1. Pre-washing with clean water
Water at room temperature. 10 to 15 minute cycle. This
pre-wash enables evacuation of the remaining residues.
2. Washing with an alkaline detergent
Typically this is soda at 2,5% at a temperature of 80°C.
20 to 30 minute cycle. This wash particularly enables
dissolving and evacuating grease and proteins.
3. Rinsing with clean water
Water at room temperature. 10 minute cycle. This rinse
enables avoiding the mixture of 2 cleaning solutions.
4. Washing with an acid solution
Typically this is nitric acid at 2,5% at room temperature.
10 to 15 minute cycle. This wash particularly enables
dissolving and evacuating proteins and inorganic salts.
5. Rinsing with clean water
Water at room temperature. Several 1 to 2 minute
cycles. These rinses enable evacuating all traces of
acid solution.
During all these CIP stages, the average speeds of the
cleaning liquids in the pipes must be between 1,5 and 3 m/s.
4.6 STERILISATION IN PLACE (SIP)
The serie C pumps are perfectly adapted to all processes
using SIP (Sterilisation In Place) : pump stopped / maxi-
mum 20 mn per cycle / 1 or 2 cycles per day.
