The assessment process must address all of the following items of evidence.
Ability to:
1. Access workplace information to identify production requirements
2. Select, fit and use personal protective clothing and/or equipment
3. Confirm supply of necessary materials and services
4. Confirm equipment status and condition
5. Start up from empty and start up from full
6. Maintain required levels in the crystallisers
7. Follow cooling and reheating profiles
8. Start up and operate in both automatic and manual modes
9. Monitor the process and equipment operation to maintain the process within the required parameters. This typically involves monitoring:
throughput
loads on crystalliser drives
sugar crystal size and distribution
massecuite conductivity
massecuite dilution rates
end of cooling and reheating temperatures
stocks of C massecuite to match pan stage throughput
equipment condition
10. Detect and report water leaks from crystalliser coils
11. Take corrective action in response to out-of-specification results
12. Report and/or record corrective action as required
13. Record workplace information
14. Demonstrate shift handover procedure
15. Shut down equipment in response to an emergency situation
16. Demonstrate an operational shut down procedure
17. Prepare equipment for cleaning/maintenance
18. Maintain work area to meet housekeeping standards
May include the ability to:
19. Use process control systems
20. Clean and sanitise equipment
21. Take samples and conduct tests
Knowledge of:
22. Purpose and basic principles of crystallisation. This includes a basic understanding of crystal growth and super saturation of solutions
23. The effect of C molasses dilution on C massecuite viscosity
24. The effect on C molasses purity of variation in:
end of cooling and reheating temperatures
residence time
25. The effect of C massecuite conditioning on low grade fugal performance
the circuit flow of this process and relationship to related processes
equipment purpose and basic operating principles of crystallization equipment
the risks and consequences of pipe failure related to massecuite decomposition
26. Services used
27. Operating requirements and parameters
requirements when starting up full crystallisers containing cold massecuite
requirements when shutting down full crystallisers containing hot massecuite
28. Significance and method of monitoring control points within the process
29. Common causes of variation and corrective action required
30. Hazards and controls
31. Lock out and tag out procedures
32. shut down sequence including massecuite pumps and reheaters
33. Requirements of both operational and long term shut down conditions to ensure the equipment is left in a safe state for the period of the shutdown and to minimise any delays in future start up
34. Procedures and responsibility for reporting problems
35. Environmental issues and controls
36. Waste handling requirements and procedures
37. Recording requirements and procedures
May include knowledge of:
38. Basic operating principles of process control where relevant. This includes the relationship between control panels and systems and the physical equipment
39. Cleaning and sanitation procedures
40. Sampling and testing procedures
Relationship with other standards
Pre-requisite units
There are no pre-requisite units for this competency standard.
Co-assessment of related units
Other units of competency relevant to the work role should be assessed in conjunction with this unit. This may include:
SUGPCPS2A Collect and prepare samples
SUGPPST2A Conduct standard tests
SUGZPCI2A Operate a process control interface
Resources required for assessment
Assessment must occur in a real or simulated workplace where the assessee has access to:
Operating procedures and related advice on equipment operation including advice on safe work practices and environmental requirements
Personal protective clothing and equipment
Product and process specifications and operating parameters
Crystalliser station equipment
Materials including C massecuite and services as required
Material Safety Data Sheets where appropriate
Housekeeping standards and procedures
Advice on environmental management issues relevant to work responsibilities
Workplace information recording systems, requirements and procedures
They may also require access to:
Cleaning procedures, sampling schedule and procedures and maintenance procedures and tools depending on the work requirements.
