Automated fermenter control at moosehead breweries, limited.
Cumberland, W.G. MacDonald, D.M. and Skinner, E.D.
The existing control system in the combi-fermenters at this brewery was found to be inadequate when expansion was required. A Matrix valving system was installed in the new tanks with the main operations of CIP, filling and emptying being carried out using a programmable controller for the sequence logic. A colour graphic video display is provided for operator reference. The system uses remote input/output racks and is controlled from a single touch key pad. An on-line printer is used for data logging. The individual tanks are controlled by a system of differential pressure cells and a Chameleon Process Micro-computer. The system yields all pertinent tank parameters including the corrected degrees Balling and controls temperature to the required process settings. The system is now working efficiently under practical conditions.
