Your challenge

Removing stubborn fouling from heat exchangers or evaporators

The growing market for protein rich products places new demands on your cleaning? With your conventional 5-step process, residues remain in the heater after cleaning?
Traditionally, conventional cleaning processes often consist of a 5-step procedure with the process steps: pre-rinse (mostly with return water); caustic (hot); intermediate rinse with fresh water, acid (hot or cold) and post-rinse with fresh water, which is why protein bounded deposits are often removed with difficulty or insufficiently. But if inadequate product removal leaves residues in the heater, re-contamination can occur rapidly due to the growth of new layers, which in the worst case can lead to the development of microbiological contamination. Shorter production times, time-consuming and exorbitant dismantling, manual cleaning work on heat transfer plates and evaporators which often remain inevitable.

We can assist you with the challenges of cleaning heat transfers or evaporators despite high protein deposits!

Our solution

A CIP concept specially developed for stubborn, burnt-in soiling

In cooperation with the Technical University of Braunschweig, a new technology has been developed to remove extreme ineradicable protein-based residues through synergistic effects of cleaning agents. In the new O&R operating cycle, specific pH ranges are explicitly used to optimise the swelling behaviour of permanent protein-based residues. The microbiological effectiveness of the process compared to the classic 5-step procedure was verified by the accredited service laboratory of the lower saxony chamber of agriculture (LUFA) Nord-West Oldenburg. The validation of the override process was concluded together with the Teaching and research institute for dairy products (LVA) in Malente.

Your Value

O&R offers the possibility of responding uniquely to cleaning demands and, in addition to a regular CIP system or as an independent module, can ensure an optimum cleaning result with reduced swelling processes during a curtailed cleaning time.


The increasing variety of products and the growing demands in the industry for unique cleaning techniques has inspired LOEHRKE to also consider cleaning and eradication of indelible protein-based residues in thermal processes. With our team we can adequately assist you. Be it in the initial pecuniary valuation or in the technical integration of the solution. We offer turnkey solutions per your request.
