Elements and Performance Criteria

1. Maintain mill flow sheet
   • Identify all breaking, reduction and dressing stages in mill
   • Show destinations for all stock separations according to operating requirements
   • Identify all optional and ancillary equipment required to control flour and by-product production
   • Identify all bins, silos, chutes, conveyors and exhausts that control processes and performance across the mill
2. Prepare for flour and by-product production
   • Establish customer requirements for shift or production period
   • Follow recipe required to meet desired production quality and quantity targets
   • Check availability of required wheat stock
   • Determine if any changes to grist stock will be required and plan for changes to settings
3. Determine break system settings
   • Adjust break rolls for desired percentage release
   • Conduct visual inspection and test sieving where required to monitor release percentage
   • Monitor break roll passages to avoid saturation of later stages
   • Set bran finishers according to workplace procedures and to ensure optimum performance
   • Set plansifters for desired grading, including adjusting spaces between plansifters for varying grains and moisture levels
   • Monitor performance of break system to ensure system is free from semolina
4. Set settings for purifiers where fitted
   • Maintain and monitor sieve covers according to workplace procedures and to ensure optimum performance
   • Monitor feed rate to purifiers according to workplace procedures and to ensure optimum performance
   • Monitor horizontal and vertical movement of sieve covers
   • Set and monitor air pressure for each aspiration section

   • Ensure purifier stock is free from flour
5. Set settings for scratch or sizing system
   • Set scratch equipment or sizing rolls according to operator instructions
   • Monitor performance of scratch and sizing rolls
6. Set settings for reduction passages
   • Set each set of reduction rolls for desired flour and capacity of succeeding reduction passages
   • Monitor covers on sifters for effective dressing from each reduction roll
   • Monitor flake disrupters and impact detachers where fitted
   • Set and monitor reduction settings to achieve required starch damage
   • Specify collection conveyors and bins for each flour stream
