Carbon infra-red mould
heating systems from
Heraeus Noblelight are
helping a specialist chocolatier
to maintain the quality of its
chocolate products, as well
providing significant savings
in space and energy costs.

The production of moulded
chocolate involves depositing
liquid chocolate into suitable
polycarbonate moulds. It is
important that the moulds
are pre-heated to a specific
temperature before the
chocolate is deposited.

PID-controlled carbon
infra-red heating systems
have been installed on all
three moulding machines.

Two of the machines run at
2.5m/min (12 moulds/
minute) while the third runs
at 3.5m/min (also 12 moulds/
min). All three machines have
a pyrometer which regulates
the energy of the infra-red
emitters to ensure all mould
temperatures are about 30°C
when filling takes place.

The result has been better
temperature control and
energy savings of about 60%.
