An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.
There must be evidence that the individual has independently coordinated the safe and efficient set-up, operation, handover and shutdown of two complete shifts of wine clarification processes. Each shift must be a minimum of eight hours. The individual must coordinate the clarification of at least two different batches of juice or wine, according to work orders.
For each shift, the individual must have:
coordinatedat least two of the following processes:
centrifuging
flotation
racking after cold settling
rotary vacuum
coordinated at least three of the following:
centrifuge equipment
flotation equipment
racking and cold settling equipment
pumps
rotary vacuum drum
storage tanks
controlled the product temperature to meet wine making specifications
communicated with at least two cellar operations workers and with at least two of the following:
wine maker
cellar operations manager
maintenance team member
laboratory team member.
For each shift, the individual must have:
coordinated at least two cellar operations workers, including scheduling start and finish times, meal and rest breaks
addressed quality issues and anomalies caused by equipment failure and operator error
