Two carbon infra-red heating
systems from Heraeus
Noblelight are helping to
ensure consistent chocolate
quality at Kinnerton
Confectionery. One is used to
pre-heat chocolate moulds
prior to filling; the other to
melt chocolate rims prior to
rim heating, which involves
the fusing of two chocolate
halves. Both retrofitted
systems have provided space
and energy savings.

It is important that moulds
are pre-heated to a specific
temperature before chocolate
is poured. If they are too
warm, the chocolate can
change its characteristics and
detemper. Too cold and the
poured chocolate will lose
shape and possibly crack.

Heraeus Noblelight
provided a trial infrared
system. This proved a success
and a full-scale 14.4kW
carbon infrared system was
installed, with a pyrometer to
ensure that moulds are heated
to exactly 29°C. A 9.6kW
carbon infra-red system was
then installed for rim heating.

The controllable heating
system has significantly
reduced reject levels.
