Page 7: Initial Cleaning
NB! Perform these operations in a clean, controlled environment. The required hygienic level must be determined individually depending the actual application. Once washed/disinfected keep the Recirculator in a suitable protective packaging until next use. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 7... -
Page 8: Choosing And Preparing A Cleaning Solution
70% solution is strong enough to quickly denature the cell proteins, with the water content helping to transport the solution into the bacteria cells. Prepare the solution on a daily basis. Preparation should be done in a clean, controlled environment. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 8... -
Page 9: Pre-Sampling Cleaning
If the sampling valve was not cleaned properly after the previous sampling, product residues may still be present in the valve chamber. If this is the case, you must clean and flush the valve chamber before starting the recirculation. In this way, the contamination of the bottle content will be minimized and not reintroduced back into the bottle. It might be necessary to pump more times, if the product is sticky or difficult to flush out. If you flush the alcohol to the floor, you may need to provide some collection method to be placed below the valve to collect the alcohol. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 9... -

NB! It is important to squeeze the rubber bulb pump rather hard in order to obtain an adequate liquid velocity, which will mechanically improve the cleaning effect. The adequate number of pumping actions is individual from application to application and must be determined by the user. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 10... -
Page 11: Sampling
Instead of using rubber caps suspended on a chain from the valve, you may use disinfected re-usable caps (rubber or steel), which are brought to the sampling point in a container filled with alcohol. This is a common practice in some industries. It is also in some industries common practice to flush with product in order to expel any alcohol remain- ing in the valve chamber. NB! If you do not flush with the product before taking the sample, you must allow some time for the alcohol to evaporate. NB! The actual sampling operation must follow your individual standard operating procedures. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 11... -
Page 12: Post-Sampling Cleaning
CIP. Your hygienic requirements and your actual application are determining factors as to whether the alco- hol may be reused for the next CIP and if so, for how many times. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 12... -
Page 13: Additional Barrier
24. For obtaining an additional barrier make sure a surface of alcohol is visible inside the top port. If not visible you may add some alcohol from a squeeze bottle with a spout. 25. Refit cap on top port The valve chamber is now filled with alcohol. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 13... -
Page 14: Re-Use Of Cleaning Solution
9. RE-USE OF CLEANING SOLUTION If pre-CIP flushing removes all visible residues the amount of product that goes into the bottle is very small, which may justify re-use of the alcohol for the subsequent cleaning processes. This must be deter- mined by the user depending on the actual application. KEOFITT CIP RECIRCULATOR USER MANUAL V.2 PAGE 14... -
Page 15: Alternative Cleaning Agents
One bottle for the alkali One bottle for the acid (only if acid cleaning is also necessary) One bottle for rinse water (letting rinse water flow to drain) NB! This User Manual does not recommend one or the other cleaning agent or cleaning proce- dure, as they may differ a lot from one industry to another, and even companies within one given industry.
