Elements and Performance Criteria

1. Determine cooling and storage system requirements
   • Available water supply is identified and analysed in line with cooling requirements for quality and quantity.
   • Components of the on-farm dairy milk cooling and storage requirements are identified to meet standard industry guidelines and herd and dairy factory needs.
   • Design considerations, including the siting of components, are identified and recorded.
   • Occupational Health and Safety (OHS) hazards are identified and risks assessed in line with workplace OHS and industry standards and reported to the supervisor.
2. Identify milk pre-cooling requirements
   • Maximum peak flow of milk delivery is measured and recorded.
   • Cooling water temperatures and quality are checked against design specifications.
   • Available milk cooling equipment is compared to design requirements and suitable equipment selected.
   • Relevant legislation including OHS and human health requirements is identified and compliance targets established.
   • Water cooling system requirements are identified in line with installed equipment and available resources.
3. Identify milk storage requirements
   • Farm milk production together with projected production increases is estimated in line with the available farm management plan.
   • Milk entry temperature and other critical design considerations are established in consultation with the shed manager and available data.
   • Vat selection is made meet shed production requirements and bulk milk collection routines.
4. Install milk cooling and storage equipment
   • Plate cooler and other components of the pre-cooling system are installed in line with established system design and industry standards.
   • Vat and refrigeration equipment are installed to meet design specifications.
   • Commissioning tests are completed as required to ensure that the operation of all elements of the cooling and storage equipment complies with performance targets and milk supply quality standards.
5. Operate and maintain milk cooling&storage equipment
   • Routine maintenance program requirements are completed in line with manufacturers' recommendations.
   • Repair and service requirements including operational faults are identified as a structured part of maintenance routines.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following identify milk cooling and storage requirements recognise and rectify operational faults in milk cooling and storage equipment perform tests on cooling towers install and maintain milk cooling and storage equipment
Context of and specific resources for assessment	Competency requires the application of work practices under work conditions Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances
