Chocolate moulds get pre-heat treat

A 9kW carbon infra-red heating system from Heraeus Noblelight is helping to ensure consistent chocolate quality while reducing production line down-times at OP Chocolate's Dowlais, South Wales, factory. The system is used to pre-heat chocolate moulds prior to filling and replaces a longestablished ceramic infra-red system.

One third the size of the old system, the new carbon medium wave system features three 3kW emitters and can be either manually or automatically controlled.

With manual control the emitter outputs can be adjusted by the operator to achieve a mould temperature of 30°C as measured by a pyrometer. With automatic control, the emitters are regulated automatically according to the pyrometer setting.
