This unit of competency covers the skills and knowledge required to make adjustments to a batch of product to bring into specification. The adjustments may be to the chemical, physical or biological properties of the batch (or some combination of these).This unit of competency applies to operations technicians who are required to demonstrate a significant understanding of the process and the equipment operation in order to interpret test results, estimate and make adjustments, and identify, correct and report operational problems.This unit of competency applies to a range of manufacturing processes, for example, chemical reaction between materials, dissolution or mixing of materials. It typically applies in batch plants where variability of materials leads to a variability in product which needs to be adjusted for.In a typical scenario a batch has been made in a batch kettle or vessel. After the batch has initially been made there will be some testing of the batch and then some adjustments will need to be made to bring it into specification. The adjustments may be to the chemical, physical or biological properties of the batch (or some combination of these). The adjustments will typically occur in the making kettle/vessel although this is not a necessary component of this unit. This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members and the control room operator, as appropriate.This unit does not apply to testing. See relevant testing unit.No licensing, legislative or certification requirements apply to this unit at the time of publication.
