123355  Manufacture a dry food product by means of a roller dryer  Level 4  NQF Level 04  30  Complete 

PURPOSE OF THE UNIT STANDARD 
A person credited with this unit standard is able to:
  • demonstrate knowledge of the manufacturing of dry food product by means of a roller dryer,
  • prepare to manufacture dry food product by means of a roller dryer,
  • dry food product by means of a roller dryer,
  • perform end of drying procedures.

    This unit standard is for anyone who has to manufacture dry food product from a concentrated mixture by means of a roller dryer.

    This unit will contribute to the full development of the learner within the food 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 food manufacturing and processing environment. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills:
    Cleaning-in-place and cleaning out-of-place.
    Representative sample taking for quality control purposes. 

    UNIT STANDARD RANGE 
    The scope of this unit standard is for anyone who has to manufacture dry food product from concentrated mixture by means of a roller dryer.

    In the context of this unit standard, roller drying includes trough-fed and spray-fed roller drying during which dry food product is manufactured. Food powder refers to non-agglomerated food powder that is difficult to reconstitute.

    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.
