Knowledge of: purpose and basic principles of the drying process, including the stages that occur during the drying process and the effect on product structure of each stage basic operating principles of equipment, including 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 quality characteristics to be achieved by the process materials preparation requirements and effect of variation on the process the flow of the drying process and the effect of outputs on downstream processes 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 drying process, such as inspecting, measuring and testing as required by the process inspection or test points (control points) in the process and the related procedures and recording requirements contamination/food safety risks associated with the process and related control measures common causes of variation, such as air temperature, air velocity, humidity and pressure, and corrective actions required if these are out-of-specification operational health and safety (OHS) hazards and controls, including limitations of protective clothing and equipment relevant to the work process requirements of different shutdowns as appropriate to the 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 procedures and responsibility for reporting production and performance information environmental issues and controls relevant to the drying 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 product/process changeover procedures and responsibilitieswhere relevant routine maintenance procedures where relevant sampling and testing associated with process monitoring and controlwhere relevant cleaning and sanitation procedureswhere relevant |
