Performance Evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.

There must be evidence that the individual has controlled mill processes and performance on at least one occasion, including:

interpreting mill flow diagrams and production requirements

identifying customer requirements

determining correct settings for equipment

setting and monitoring break and reduction system equipment

achieving flour specifications through correct use of grist and mill settings

monitoring equipment settings and performance

adjusting mill settings for breakdowns and other contingencies

setting all related processes for:

break

scratch

sizing

reduction and other milling

supervising wheat conditioning

ensuring settings take into account the capability of equipment and the need to avoid imbalances, product build-ups and chokes

ensuring all grain and flour tests are carried out to required schedule and procedures

applying safe work practices and identified work health and safety hazards and controls.

Knowledge Evidence

An individual must be able to demonstrate the knowledge required to perform the tasks outlined in the elements and performance criteria of this unit. This includes knowledge of:

alternative and historical milling techniques, including:

stone grinding

‘low’ or one pass through grinding

use of small manual or electric milling machines

semolina process compared with traditional flour milling process

conventions and techniques in drawing mill flow diagrams

characteristics of different grist and their milling requirements

purpose, design and steps of the break process, including:

overall aim of removing bran from endosperm in large pieces while minimising bran powder and flour

roller design

flute design

roller speed

number of passages

destinations of product from each break roll

purpose, design and principles of the purification process, including:

sieve design

role of sifting, shaking, gravity and aspiration (upward air)

screening decks

exhaust ports and chambers

collection of throughs

overtails

relationship of purification to later reduction stages

scratch equipment and process to remove small pieces of bran and germ from endosperm after sizing or purification

relationship of particle size to reduction roller efficiency

reduction that grinds flour into required fineness while controlling damage to starch granules and minimising abrasion to any bran and germ particles present

features and performance characteristics of milling equipment as specified in manufacturer reference material

relationship between total dressing surface ratio to mill capacity

calculation of break roll percentages

techniques to avoid imbalances, product build-ups and chokes

mill balance requirements and techniques, including:

ensuring that stock does not return to immediate preceding passage or equipment

feed to first break at a constant rate

evenness of feed into rolls

maintenance of conveyor and air settings to achieve constant feed

calculation of mill performance, including:

invisible loss rate

theoretical and actual milling loss rate

procedures to track traceability of product.

Assessment Conditions

Assessment of the skills in this unit of competency must take place under the following conditions:

physical conditions:

a mill or an environment that accurately represents workplace conditions

resources, equipment and materials:

personal protective equipment

break and reduction roll equipment and related services

conditioned grain suitable for the break and reduction roll process

sampling schedules and test procedures and equipment

specifications:

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

documentation and recording requirements and procedures.

relationships:

operators/team members.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
