PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard is able to:
  • demonstrate knowledge of homogenisation of liquid dairy products,
  • prepare to homogenise a liquid dairy product,
  • homogenise a liquid dairy product,
  • perform end of homogenisation procedures.

    This unit standard is intended for any person who works in a dairy factory with the responsibility of homogenising liquid dairy products.

    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:
    Cleaning procedures, handling of equipment and chemicals.
    Representative sample taking for quality control purposes. 

    UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to homogenise a liquid dairy product.

    In the context of this unit standard, a liquid dairy product includes milk, cream and any other dairy based liquid mixture used for further processing into dairy products.

    The level assigned to this unit standard is appropriate because the process requires a range of well-developed skills and offers a significant choice of procedures. Some relevant theoretical knowledge, interpretation of available information, discretion and judgement, as well as a range of known responses to familiar problems are employed. The application of this unit standard is to qualify the person for certification in skilled occupations and sub-trades.
