PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard is able to:
  • demonstrate knowledge of sterilising liquid dairy products,
  • prepare to sterilise a liquid dairy product,
  • sterilise a packed liquid dairy product in a steri-tower,
  • perform end of sterilising procedures.

    This unit standard is for anyone who works in a dairy facility and needs to sterilise a previously packed liquid dairy product in a steri-tower.

    This unit will contribute to the full development of the learner within the dairy manufacturing environment by providing recognition, further mobility and transportability within the field of manufacturing and assembly. The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and upliftment within the dairy manufacturing and processing environment.

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills:
    Representative sample taking for quality control purposes.
    Cleaning-in-place and cleaning out-of-place.
    Procedures for the preparation of milk for sterilised product manufacturing. 

    UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to sterilise a previously packed liquid dairy product in a steri-tower.

    The context of this unit standard includes single- and two-stage steri-towers.

    The level assigned to this unit standard is appropriate because the process requires a wide range of technical skills and offers a considerable choice of procedures. A broad knowledge base incorporating some theoretical concepts, analytical interpretation of information, informed judgement and a range of sometime innovative responses to concrete but often unfamiliar problems are employed. The application of this unit standard is to qualify the person for certification in advanced trade and technical occupations.
