Elements and Performance Criteria

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Mill
The term mill is used to refer to the whole mill site including the actual milling equipment, equipment used for associated processes, and transport, warehouse, maintenance, testing and administration facilities.
Mill flow diagram
A mill flow diagram is a representation of the flow of products through the mill process.
Mill balance
Mill balance refers to achieving settings where each passage in the grain breaking and reduction process ensures that other passages and equipment operate on optimum quantity and quality of stock. It also refers to ensuring that the overall surface area (available contact area for product) is appropriate for that stage or passage and the mill as a whole.
Grain acceptance specifications may include:
weight
protein
moisture
odour
foreign object criteria
pests and pest treatment residues.
Grinding can refer to:
the break system which is the process of opening up the grain and scraping away the endosperm
the reduction system which is the process of reducing the endosperm until it can be classified as flour.
Extraction rate
The extraction rate is the number of parts by weight of flour obtained from a hundred parts of grain.
Optional equipment
Optional equipment is milling equipment not found in every mill. Examples include:
bran finishers/brushes
germ production machines
bran rolls
bran grinding rolls
micro-detachers.
Throughs
Stock which falls through apertures at each sifting or purifying stage.
Overtails
Stock left after throughs are collected and which depending on the stage may be:
endosperm particles with adhering bran
mainly bran
bran and endosperm requiring further treatment.
Wheatfeed
By product of the milling process including bran of varying sizes and varying amounts of attached endosperm.
Scalping
Scalping is the separation of coarse overtails after grinding
Roll adjustment
Adjustment of roll gaps may be done manually or through computerised.

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
Assessment must be carried out in a manner that recognises the cultural and literacy requirements of the assessee and is appropriate to the work performed. Competence in this Unit must be achieved in accordance with food safety standards and regulations.
Critical aspects for assessment and evidence required to demonstrate competency in this Unit
Evidence of ability to:
interpret mill flow diagrams and production requirements
set and monitor break and reduction system equipment
achieve flour recipes through correct use of grists and mill settings
adjust mill settings for breakdowns and other contingencies.
Context of and specific resources for assessment
Assessment must occur in a real or simulated workplace where the assessee has access to:
personal protective clothing and equipment
work procedures, including advice on safe work practices, food safety, quality and environmental requirements
equipment manuals including operating parameters
specifications, control points and processing parameters
break and reduction roll process and related equipment and services
conditioned grain suitable for the break and reduction roll process
sampling schedules and test procedures and equipment as required
documentation and recording requirements and procedures
cleaning procedures, materials and equipment as required.
Method of assessment
This Unit should be assessed together with core Units and other Units of Competency relevant to the function or work role.
Guidance information for assessment
To ensure consistency of performance, competency should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities.
