PURPOSE OF THE UNIT STANDARD

A learner who has achieved this unit standard will be competent in: Controlling juice sedimentation in the clarifier to obtain good quality clear juice.

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

To enter a learning programme for this unit standard or to be assessed against this unit standard, the learner is assumed to have: Literacy and communications NQF 1 Numeracy NQF 1 Basic understanding of sugar processing Basic knowledge of quality assurance systems An understanding of general safety in the workplace at NQF 1 or equivalent

UNIT STANDARD RANGE

General guide for scope, context and level The learner is expected to perform the specific outcomes as reflected in this unit standard without direct supervision, but with access to standard operating procedures.

Specific Outcomes and Assessment Criteria:

SPECIFIC OUTCOME 1

Demonstrate an understanding of juice sedimentation.

OUTCOME NOTES

Explaining the basic principles of juice sedimentation Identifying and explaining the purpose of the various equipment associated with juice clarification

ASSESSMENT CRITERIA

ASSESSMENT CRITERION 1

Assessors will observe, confirm and evaluate evidence that will indicate that learners have demonstrated competence in each of the specific outcomes. In this unit standard the following specific criteria should be used: Understanding of: Basic principles of flocculation and juice sedimentation Reasons for: Monitoring process variables (including but not limited to pH, purity and brix) and taking corrective actions Starting up the clarifiers and coordinating with ancillary equipment according to standard operating procedures Shutting down the clarifiers according to standard operating procedures Informing relevant parties of clarification performance during the shift Consequences of not Adhering to safety procedures Measuring clear juice clarity and adjusting mixed juice temperature and flow as well as flocculant addition accordingly Maintaining mud consistency and withdrawal according to process requirements

SPECIFIC OUTCOME 2

Prepare for juice sedimentation.

OUTCOME NOTES

Starting-up the clarifier(s) and ancillary equipment according to standard operating procedures Adhering to safety procedures

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD:

This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
