Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

3. Confirm supply of necessary materials and services

4. Prepare lime, flocculant and saccharate for addition

5. Liaise with other work areas

6. Confirm equipment status and condition

7. Set up and start up the process in both automatic and manual modes

8. Monitor the process and equipment operation to maintain the process within the required parameters. This typically involves visual inspections and conducting tests to monitor characteristics such as:

juice temperatures

steam pressure

condensate flow and quality

throughput

juice pH

ESJ turbidity

addition rates

raw juice quality

clarifier mud levels and quality

equipment condition

9. Monitor supply and flow of materials to and from the process

10. Take corrective action in response to out-of-specification results

11. Record workplace information

12. Demonstrate shift handover procedure

13. Shut down equipment in response to an emergency situation

14. Demonstrate an operational shut down procedure

15. Prepare equipment for cleaning/maintenance

16. Maintain work area to meet housekeeping standards

May include the ability to:

17. Use process control systems

18. Clean and sanitise equipment

19. Take samples and conduct tests

Knowledge of:

20. Purpose and basic principles of clarification. This includes heating, liming, juice degasification and flocculant addition

21. The circuit flow of this process and relationship to related processes. This includes the consequences of poor clarification on downstream processes
