The amount of time required to clean the mixer/cooler combination shouldn’t be
underestimated and it may be necessary to remove the mixing tools to clean properly.
Solvent may be needed to remove ‘stubborn’ stains. Use of polished stainless internals
can help reduce build up and cleaning time, although care must be taken not to scratch the
polished surface as this will promote adhesion and extend cleaning time.
Use of internal cooled mixing tools can help prevent adhesion to the tools. However, experience has
shown that use of cooled tools extends the heat up time and introduces the risk of water
ingress, which is not recommended with aluminium present. Also, cooled tools are more
complex to remove for cleaning. 'Use of cooled tools therefore is not a good option for
the Bonding process'.
