At-line purity sensor to enhance the monitoring, control, and performance of pan stage
Currently the laboratory determinations of purities of pan stage products which are used for pan stage management are for the period ended 8 or 12 h previously, because the conventional sucrose and dry substance measurements are time-consuming. These values are then used by production staff to set operational plans on the pan stage.
The principle of using peak electrical conductivity values as a measure of true purity was used by Mulgrave Mill to provide a rapid method for determining the purities of pan stage products. Subsequently other mills have been using the system in their laboratories for routine analyses of pan stage products. The system provides a cost and time-efficient method for obtaining ‘true purity’ values.
This project aims to build and evaluate an in-factory automated measuring device that measures the true purity of syrup, A and B molasses in a single unit. The frequency of measurement will allow the purities in stock tanks to be estimated.
