Chocolate Processing Automation
Tempering-through-moulding pipework automated for the thermal stability premium chocolate production requires.
Scope & approach
Haigh's Chocolates is one of Australia's most respected premium chocolate manufacturers. Chocolate processing requires precise temperature control at every stage, from tempering through to piping and moulding, and any inconsistency shows directly in product quality. Metromotion Controls delivered an automation system covering the chocolate pipework, including temperature monitoring, flow control and the sequence logic required to manage the production process reliably. The system was designed around the specific requirements of premium chocolate manufacturing, where process stability directly determines product quality and yield.
What was delivered
- Chocolate pipework temperature and flow control was automated, replacing manual process management.
- The control system was designed for the thermal sensitivity requirements of premium chocolate production.
- Operator visibility of process conditions improved, giving the production team earlier warning of out-of-specification conditions.
Scope items
- Automation of chocolate pipework including temperature monitoring and flow control
- Sequence logic for production process management aligned to specialty chocolate manufacturing requirements
- Operator interface for live process visibility and early warning of temperature or flow deviations
- Commissioning support and operator handover at the Adelaide production facility
Services and sectors behind this work
Industrial automation and control systems
Controls engineering for new production lines, brownfield upgrades and integrated plant systems.
PLC, SCADA and HMI programming
PLC logic, SCADA architecture, HMI standards, alarming and historian integration for manufacturing sites.
Control panel engineering
Electrical design, control cabinet upgrades and panel build documentation for industrial projects.
Food and beverage automation
