Invensys AVP

The following project for Invensys APV and George Weston Foods involved the installation, commissioning and partial design of two fully automatic bread mixers for the Newcastle plant.

Each mixer comprises of an 110kW and various smaller Allen Bradley VSD's. Various types of instrumentation are installed on the machines including pressure, flow, temperature, weight and level.

Six Allen Bradley SLC 5/05 processors were installed on the Ethernet network to form the basis of the control system. Two Xycom touch screens utilising Wonderware SCADA software performed the batching functions and also the operator interface between plant and machines.

Category three safety systems are also integrated into the machines. To maintain production original mixer was removed and the new units installed whilst still retaining full plant production. Three more pairs of these mixers have also been installed at the new bakery in Chullora, Sydney.
