The idea is to make the system as flexible and easy to use as possible. To do this 2 variables will be used at all times to define if the system will be cooling, heating, or nothing. The logic is is shown below:
Both the Cold Box and the Conical Fermenter will be controlled separately. By controlling these process separately we will be able to ferment different types of beer at the same time. Because a PLC will be used to control this process it should be easy to track where each beer is in the fermentation process. The Control logic which will control the heating and cooling pumps is as follows:
This is the basis of what is needed to brew different beers. This logic will always be used regardless of the stage of the brew process Primary, Diacetyl Rest, Crash, Secondary. I will followup with the diagram which will show each of the process steps in a later post for now we have temperature control... O, yea not to mention the data logging. The data logging will be essential so that we understand what a beer experienced during the fermenation process. In logging this information we will be able to re-create a beer over and over again.
