• The industry that processes carcasses and offal, rendering, ensures that
the human food chain remains free from these animal remains.
• They are unsuitable to be reprocessed into anything else but animal feed.
• The rendering process starts when carcasses and offal arrive. First, all is
ground and left to boil for twenty minutes in water at 130°C, then the liquid
is transferred to a flash tank.
• An air-cooled rendering condenser removes most of the cooking steam
under very slight overpressure.
• It aims to condense the steam and cool the condensate to a maximum of
35°C.
• This is necessary as bio waste water purification processes the
condensate and active bacteria in the purification will die if temperatures
reach more than 40°C.
• The reason behind condensing the steam is its awful smell which is
neutralised during this process.
• The broth of meat, which is what is left in the flash tank, is dried using the
heat in disk dryers until it has reached a water content of 5%.

Challenge / question
First grind up. Leave to cook for twenty minutes. Then
the flash tank, condensation and disk dryers.
• 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.

Solution
First grind up. Leave to cook for twenty minutes. Then
the flash tank, condensation and disk dryers.
• 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.

Solution
First grind up. Leave to cook for twenty minutes. Then
the flash tank, condensation and disk dryers.
• 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.
