Knowledge of: purpose and basic principles of conching chocolate, including: processing stages in chocolate making and the role of conching ingredients used in chocolate and those added during conching, such as ingredients in different types of chocolate as appropriate to production requirements and an understanding of the quality requirements and role of each main ingredient changes that occur in ingredients during conching significance of viscosity and methods of adjustment basic operating principles of equipment, such as main equipment components, status and purpose of guards, equipment operating capacities and applications, and the purpose and location of sensors and related feedback instrumentation services required and action to take if services are not available the flow of the conching process and the effect of outputs on downstream processes quality requirements of mass and ingredients used, and effect of variation on process performance and outputs quality characteristics required of the conching stage operating requirements and parameters and corrective action required where operation is outside specified operating parameters typical equipment faults and related causes, including signs and symptoms of faulty equipment and early warning signs of potential problems methods used to monitor the conching process, including an understanding of viscosity testing procedures and other inspections and tests as required inspection or test points (control points) in the process and the related procedures and recording requirements contamination/food safety risks and related control measures common causes of variation and corrective action required occupational health and safety (OHS) hazards and controls requirements of different shutdowns as appropriate to the conching process and workplace production requirements, including emergency and routine shutdowns and procedures to follow in the event of a power outage isolation, lock out and tag out procedures and responsibilities product/process changeover procedures and responsibilities procedures and responsibility for reporting production and performance information environmental issues and controls relevant to the conching process, including waste/rework collection and handling procedures related to the process basic operating principles of process control where relevant, including the relationship between control panels and systems and the physical equipment sampling and testing associated with process monitoring and control where relevant routine maintenance procedureswhere relevant cleaning and sanitation procedureswhere relevant |
