Required Skills
Required skills includes: |
Note: The following required skills should be applied as appropriate to the equipment and processes that are used in the particular workplace. Ability to: Access workplace information to identify culture propagation requirements Select, fit and use personal protective clothing and/or equipment Confirm supply of necessary product, materials and services Liaise with other work areas Prepare product and materials as required. This may include: culture yeast slopes oxygenated wort yeast nutrients oxygen supply and sterilisation wort heating wort sterilisation Confirm equipment status and condition. This may include checking: cleaning and/or sterilisation requirements have been met position and alignment of valves integrity of door seals and small vessel tubing and condition of gas (oxy) filters Start up the process Monitor the process and equipment operation to identify out-of-specification results or non-compliance. This may involve sampling and checking: temperature (wort) wort gravity wort oxygenation levels yeast cell counts yeast viability Monitor supply and flow of product and materials to and from the process Take corrective action in response to out-of-specification results or non-compliance Report and/or record corrective action as required Conduct product and batch changeovers Follow confined space entry policies and procedures when required Sort, collect, treat, recycle or dispose of waste Shut down equipment in response to an emergency situation Shut down equipment in response to routine shutdown requirements Record workplace information Maintain work area to meet housekeeping standards Prepare equipment for cleaning. This may involve draining and/or dismantling equipment, and removing waste either manually or by rinsing, in preparation for sanitation Identify, rectify and/or report environmental non-compliance Carry out routine maintenance Use oral communication skills/language to fulfil the job role as specified by the organisation, including questioning, active listening, asking for clarification and seeking advice from supervisor Work cooperatively within a culturally diverse workforce |
Required knowledge includes: |
Note: The following required knowledge should be applied as appropriate to the equipment and processes that are used in the particular workplace. Knowledge of: Purpose and principles of propagating yeast cultures Relationship of propagation to alcoholic fermentation Stages and changes which occur during culture propagation Effect of process stages on end product Quality characteristics and uses of yeast cultures Product and materials preparation requirements and effect of variation on the process Main methods used in propagating yeast for beer production The fermentation reaction for yeast cultures Techniques that may be used to manipulate the propagation process and end product characteristics, including: temperature yeast strain wort stream wort gravity additions (nutrients) oxygen Process specifications, procedures and operating parameters Equipment and instrumentation components, purpose and operation Basic operating principles of process control systems where relevant Services used Significance and method of monitoring control points within the process Common causes of variation and corrective action required Occupational health and safety (OHS) hazards and controls, specifically confined space entry Lock-out and tag-out procedures Procedures and responsibility for reporting problems Environmental issues and controls Shutdown and cleaning requirements associated with changeovers and types of shutdowns Waste handling requirements and procedures Recording requirements and procedures Routine maintenance procedures Aseptic techniques |
Evidence Required
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: use personal protective equipment and follow other specified OHS procedures check and prepare product and any additions, including check of quality of yeast cultures before use check and confirm readiness of equipment before operation start propagation process correctly monitor propagation process control points for performance against specifications take appropriate corrective action for out-of-specification process and equipment performance collect waste and store, treat or dispose of appropriately record information appropriately. |
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 as required work procedures, including advice on company practices, safe work practices, food safety, quality and environmental requirements instructions, information, specifications and schedules as required equipment, services and corresponding information as required products and materials as required internal and external customers and suppliers as required cleaning procedures, materials and equipment as required documentation and recording requirements and procedures. |
Method of assessment | This unit should be assessed together with other units of competency relevant to the function or work role. |
Guidance information for assessment | To ensure consistency in one's performance, competence 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. |
Range Statement
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. | |
Policies and procedures | Work is carried out in accordance with workplace procedures, licensing requirements and legislative requirements |
Workplace information | Workplace information can include: Standard Operating Procedures (SOPs) specifications production schedules and instructions routine maintenance schedules work notes Material Safety Data Sheets (MSDS) manufacturer instructions verbal direction from manager, supervisor or senior operator. |
