A system designed to take automatic control of the wort boiling process in a brewery so that an increase in consistency could be achieved and savings could be made in steam usage.





Brew quality recipes were created which were based on a change in specific gravity over a defined boil time period. They included acceptable underboil tolerances and when insufficient steam had been available, reboil time periods. For any batch run the operator could select and view the required recipe and enter the gyle number for the batch.

Key Benefits

Wort Boiling Control
  • Improvement in product consistency
  • Reduction in steam usage (10 to 20%)
  • Optimised boil time to increase throughput
  • Unlimited brew quality recipes
The system would then control the boiling process according to the recipe using a pair of linked software PID controllers, one for temperature and one for energy. At the end of the process, the results were stored into an Microsoft Access compatible database under the gyle name for later review by the management.

The system also had a facility for reminding the operator when to make hops, finings and caramel additions to the copper.
