Air-cooled cooler for rendering  

Challenge / question

One of our clients is faced with a high level of fouling and corrosion during the process due to aggressive cooking steam. The process operators lack knowledge of the equipment. Production is paramount as the client is paid according to the number of processed carcasses and amount of offal. The client requires a solution for the corrosion problems. He would like an operator-friendly installation that is easy to keep clean and has an absolute minimum of downtime.

Our solution

All our components that come in contact with steam are made from stainless steel. Clasps on lids enable quick and frequent cleaning. Inspection eye-glasses are put in place to keep on eye on things. We found out that the operators release steam of 100°C on the condenser after the installation restart, even when it is freezing outside. The tubes of every 'normal' condenser that has welded and/or rolled tube-to-plate connections would bend due to the less optimal steam distribution.

In order to prevent this from happening, we have welded the tubes in our air-cooled condenser only on one side. The other side has a special sliding connection. Therefore, the tubes are able to individually expand and shrink free of tension. This prevents other tubes with less steam from having to bear a transfer of tension forces. The result is a complete and distortion free cold/hot start condenser. The operators can rest assured when releasing steam in full flow on our condensers.
