Using Sensors and Data Analysis to Calculate Effective and Ineffective CIP Wash Times

They cannot indicate the level of clean. Most CIP objects are easy to clean but the safety margins are dictated by the more challenging objects. Data from over 200 dairy production sites globally show that most washes can be cut to half of the original times, but how can you safely reduce CIP wash cycles with confidence that you are still getting a good clean?</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></p> <h6><strong><span data-contrast="auto">How to Safely Shorten CIP Washes</span></strong><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></h6> <h6><strong><span data-contrast="auto">CIPTEC Spectrophotometer Sensors</span></strong><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></h6> <p><span data-contrast="auto">Understanding where CIP optimization opportunities exist begins with collecting data from the washes. Diversey CIPTEC's patented approach uses spectrophotometer sensors to measure light beams going through the CIP pipe on the return and forward spectrum. Most of the light passes through the water, but chemicals and milk products in the water will absorb light allowing us to detect the amount of soil in the cleaning liquids and when soils have been removed. This defines effective and ineffective phase times.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></p> <h6><strong><span data-contrast="auto">Data and Statistical Analysis</span></strong><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></h6> <p><span data-contrast="auto">CIPTEC sensor data is combined with additional CIP parameters such as conductivity, flow and temperature to enable a full analysis of the different phenomena happening during each wash-cycle and the discovery of anomalies causing variance. Applying statistical analyses to the dataset will reveal the optimal length of your CIP washes including a 6-sigma safety margin. If an object is washed once per day, increasing your safety margin from 4-sigma to 6-sigma will reduce the probability that the object is still unclean from twice a year to less than once in 800 years.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></p> <p><span data-contrast="auto">Take an example of an 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.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></p> <h6><strong><span data-contrast="auto">Why is Spectrophotometer better than Conductivity?</span></strong><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></h6> <p><span data-contrast="auto">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 because:</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></p> <ol> <li data-leveltext="%1." data-font="Arial" data-listid="37" data-list-defn-props="{&quot;335552541&quot;:0,&quot;335559685&quot;:1080,&quot;335559991&quot;:360,&quot;469769242&quot;:[65533,0],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;%1.&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}" aria-setsize="-1" data-aria-posinset="1" data-aria-level="1"><span data-contrast="auto">The conductivity of milk is relatively close to that of water.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:200,&quot;335559740&quot;:276}">&nbsp;</span></li> </ol> <ol> <li data-leveltext="%1." data-font="Arial" data-listid="37" data-list-defn-props="{&quot;335552541&quot;:0,&quot;335559685&quot;:1080,&quot;335559991&quot;:360,&quot;469769242&quot;:[65533,0],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;%1.&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}" aria-setsize="-1" data-aria-posinset="2" data-aria-level="1"><span data-contrast="auto">Both milk residues and water will lower the conductivity of the CIP chemical phase.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:200,&quot;335559740&quot;:276}">&nbsp;</span></li> </ol> <p><span data-contrast="auto">However, 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.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></p> <h6><strong><span data-contrast="auto">Spectrophotometers can detect:</span></strong><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}">&nbsp;</span></h6> <ul> <li data-leveltext="" data-font="Symbol" data-listid="38" data-list-defn-props="{&quot;335552541&quot;:1,&quot;335559685&quot;:1080,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}" aria-setsize="-1" data-aria-posinset="1" data-aria-level="1"><span data-contrast="auto">Milk or other product amounts in the first rinse.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:200,&quot;335559740&quot;:276}">&nbsp;</span></li> <li data-leveltext="" data-font="Symbol" data-listid="38" data-list-defn-props="{&quot;335552541&quot;:1,&quot;335559685&quot;:1080,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}" aria-setsize="-1" data-aria-posinset="2" data-aria-level="1"><span data-contrast="auto">Down to 0.5 ppm of milk in cleaning chemicals.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:200,&quot;335559740&quot;:276}">&nbsp;</span></li> <li data-leveltext="" data-font="Symbol" data-listid="38" data-list-defn-props="{&quot;335552541&quot;:1,&quot;335559685&quot;:1080,&quot;335559991&quot;:360,&quot;469769226&quot;:&quot;Symbol&quot;,&quot;469769242&quot;:[8226],&quot;469777803&quot;:&quot;left&quot;,&quot;469777804&quot;:&quot;&quot;,&quot;469777815&quot;:&quot;hybridMultilevel&quot;}" aria-setsize="-1" data-aria-posinset="3" data-aria-level="1"><span data-contrast="auto">Chemical residues in the final rinse.</span><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335559739&quot;:200,&quot;335559740&quot;:276}">&nbsp;</span></li> </ul>
