Do most of your CIP washes take too long?
Nope, you don´t need 30 minutes of hot caustic to clean a simple stainless steel pipe.
But do you have occasionally problems with your cleaning results?
Although most washes take too long, you may still have few challenging objects, that will not come clean.
We’ve patented a solution to cut the excess time of each CIP-wash.
Less Waste Water
Turnkey project model for dairies and breweries
How do we achieve all this? We’ve developed a turnkey project model for CIP optimizations. We analyze the entire CIP-process from start to end multiple times. And that’s why we’re the only provider to guarantee results. Our services cover:
Understanding your CIP begins with collecting data from the washes.
Statistical analyses reveal the length of the safety margins of your washes.
Safety to 6 sigma level
If an object is washed once per day, increasing your safety margin from 4 sigma to 6 sigma will reduce the number of times the object is still unclean from twice a year to less than once in 800 years.
Reduce your CIP times by 60%
Most CIP objects are easy to clean but the safety margins are dictated by the challenging objects. Data from over 200 sites globally show that majority of washes can be cut to half of the original times.

Comparing return and forward spectrum
When there is more absorbing material in the return than in the forward CIP line the phase is still removing dirt from the object. When both signals are in the same level, no more dirt comes off the cleanable object. This defines effective and ineffective phase time.
Seeking variance from other parameters
The TTS-Ciptec system includes others such as conductivity, flow and temperature during the wash. This data enables analysis of different phenoma of the wash and discovery of anomalies causing variance.
An example of intake pipeline wash which has been utilized for raw milk transfer. The example shows that wash phases consist of effective and ineffective time. It also shows that acid has no effect as there is no heat treatment and thus no mineral build up. Acid could be used once per week to passivate the stainless steel.
Methodology of the CIP optimization
What happens during the wash?
Spectrophotometers detect contaminants at ppm-level
Spectrum absorption measurement enables you to detect the amount of soil in your cleaning liquids.
A spectrophotometer measures a light beam going through the CIP pipe. Most of the light passes through the water, but chemicals and milk products in the water will absorb light.
Why better than conductivity?
The difference in conductivity between tap water and cleaning solutions makes conductivity meters practical for controlling the chemical concentration and phase separation in CIP lines.
Whereas conductivity can detect a 0.1 % change in chemical/water concentration, it is limited in detecting milk residues from water or from chemicals, as
a) The conductivity of milk is relatively close to that of water.
b) Both milk residues and water will lower the conductivity of the CIP chemical phase.
But milk residues will be seen accurately by absorption, either from CIP chemicals or water, as milk residues absorb much more light than water or CIP chemicals.
Spectrophotometers can detect
Milk or other product amounts in first rinse.
Down to 0.5 ppm of milk in cleaning chemicals.
Chemical residues in the final rinse.
