Ability to: access workplace information to identify distillation requirements select, fit and use personal protective clothing and/or equipment confirm supply of necessary product, materials and services. This may include checking temperature and alcoholic strength liaise with other work areas prepare product and materials as required. This may include heating the incoming product confirm equipment status and condition. This may include checking: monitoring equipment air pressure from compressor fuel intake water flow to condensers receiver vessel integrity of lines and fittings set up and start up the process. This will include any tests or procedures required to meet Customs and Excise regulations monitor the process and equipment operation to identify out-of-specification results or non-compliance. This may involve monitoring: wine feed alcohol content of the feed cooling water flow rates to condensers steam input flow rates volume of charge temperature of low wine distillate alcoholic strength of low wine distillate heat source reflux temperatures temperature of incoming wine temperatures throughout still and/or column temperature and strength at take-off point evaporation rates charge characteristics pressure of still and/or column condensate rate or flow monitor supply and flow of product, materials and services 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 or batch changeovers take samples and conduct tests shut down equipment in response to an emergency situation shut down equipment in response to routine shutdown requirements prepare equipment for cleaning. This may involve draining and/or dismantling equipment, and removing waste either manually or by rinsing, in preparation for cleaning and sanitation record workplace information. This will include meeting the requirements of Customs and Excise regulations maintain work area to meet housekeeping standards ensure that all Customs and Excise regulations are adhered to sort, collect, treat, recycle or dispose of waste according to enterprise procedures clean and sanitise equipment according to enterprise procedures carry out routine maintenance according to enterprise procedures perform transfer operations according to enterprise procedures perform heat exchange operations according to enterprise procedures identify, rectify and/or report environmental non-compliance according to enterprise procedures 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 |

Knowledge of: purpose and principles of distillation, including definition of the following terms: liquid vapour vapour pressure boiling point dew point bubble-point operating principles of stripping (analyser) columns link to related processes. This will include the source of the product to be distilled and any further processing requirements of the low wine distillate stages and changes which occur during stripping operations. This will include critical temperatures and specific components affected effect of process stages on low wine production quality characteristics and uses of low wine product and materials preparation requirements and effect of variation on the process process specifications, procedures and operating parameters equipment and instrumentation components, purpose and operation basic operating principles of process control systems where relevant sampling and testing procedures 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. This will include: emergency flooding procedures emergency evacuation procedures 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 recording requirements and procedures operation of Customs and Excise regulations waste handling requirements and procedures where relevant cleaning and sanitation procedures where relevant routine maintenance procedures where relevant transfer procedures where relevant heat exchange procedures where relevant |
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 product before commencing lees stripping operations. This may include checking temperature and alcoholic strength prepare and confirm status of equipment before commencing lees stripping process monitor process control points and equipment during lees stripping process monitor feed and distillate for conformance to specifications take corrective action in response to out-of-specification results or non-compliance demonstrate knowledge of OHS hazards, controls and emergency procedures undertake routine and emergency shutdowns 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. |
