Two carbon infrared heating systems from Heraeus Noblelight are helping to ensure consistent chocolate quality at Kinnerton Confectionery, which produces advent calendars, clusters, chocolate figurines and more.

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

To prevent this, Kinnerton had previously used both metal element heaters and a warm-air heating system, but this resulted in a number of filled moulds being excessively heated and also took up considerable space and was difficult to control.

In an effort to solve these problems, Kinnerton contacted Heraeus Noblelight, which provided a trial infrared system.

This proved so successful that a full-scale 14.4kW carbon infrared system was installed, featuring a pyrometer to ensure that the moulds are heated to exactly 29ºC. Subsequently, a second 9.6kW carbon infrared system was installed for rim heating.

Key benefits of product application

  • The Heraeus Noblelight carbon infrared system was retrofitted easily into the available space.
  • It provides precisely controllable heating for both the moulds and the chocolate rims.
  • Reject levels have been significantly reduced and quality improved.
  • The systems have provided significant space and energy savings.
