Required skills include: |
Note: The following required skills should be applied as appropriate to the equipment and processes that are used in the particular winery or workplace. Ability to: access workplace information to identify filtration 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: pre-mixing product tank to distribute solids evenly pre-coating filter drum surface confirm equipment status and condition. This may involve checking the screen or cloth condition and receival vessels set up and start up the process monitor the process and equipment operation to identify out-of-specification results or non-compliance. This may involve monitoring: filter vacuum flow rate media type or grade precoat slurry precoat discharge product loss dilution oxidation relevant product characteristics (e.g. turbidity, solids content and type) 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 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 cleaning and sanitation identify, rectify and/or report environmental non-compliance clean and sanitise equipment according to enterprise procedures take samples according to enterprise procedures carry out routine maintenance 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 |
Required knowledge includes: |

Knowledge of: purpose and principles of rotary vacuum filtration link to related processes stages and changes which occur during rotary vacuum filtration effect of process stages on end product quality characteristics and uses of rotary vacuum filtration product product and materials preparation requirements and effect of variation on the process main methods used in rotary vacuum filtration 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 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 cleaning and sanitation procedures where relevant sampling procedures where relevant routine maintenance procedures where relevant |
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 supply and status of product and filter media before operating filter assess need for and undertake any required pre-mixing of product tank and coating of drum check rotary vacuum filter equipment status and condition before commencing operation monitor rotary vacuum filter process control points and equipment during filtration process take corrective action in response to out-of-specification results or non-compliance demonstrate knowledge of OHS hazards, controls and emergency procedures 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. |
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. | |
