Control system puts icing on the bake
The new controls cover all the elements of a fully integrated Tweedy mixing system: ingredient handling and weighing, mixing, and tub hoist. The new controls have been retrofitted to existing Tweedy installations as the process, mechanical and electrical attributes of the existing system have been retained.
The touch-screen operator interface provides clear, at-a-glance visualisation of the process with easy and intuitive operation using graphical button labels wherever possible.
Fault finding is enhanced by filtering of alarms to display the primary cause of a stoppage but not the consequential alarms, which significantly reduces the time needed for operators to identify and rectify a problem. Another new feature is process alarms, which alert operators to potential variations that can affect the dough and enables them to prevent stoppages downstream.
Operationally, a major gain is more immediate updating of all recipe and process settings. Changes can be made up to the moment mixing starts: conventionally there may be up to a two-mix delay while settings are amended. The benefits of any changes needed to improve product quality or plant efficiency are thus seen immediately.
