I am a man of many skills. However, control electronics are not one of them and I’m after some help.
I need to brew a hell of a lot of beer for August as I have somewhat foolishly shot my mouth off and said I’ll make all the beer for my wedding. This means making ~200l on my little homebrewing kit. I’ve ordered a 60l fermenter so that I can double brew and speed things up a bit. However a 60l fermenter is a right pain to lug in and out of a fridge to try and control the fermentation temperature and, to crash chill.
What I want to do is to be able to submerge a stainless cooling coil which I already have, in the fermenting beer and connect it to the cold water recirc of a Maxi 210 chiller that I also already have. However I am going to need some sort of PLC unit and a temperature probe to to talk to each other so that I can set a high and low value for the temperature and some sort of switch that I can wire into the recirc pump’s power supply to turn it on and off.
Anyone built anything similar or have a cheaper, easier, more elegant way of doing it? Below is a rough sketch of what I want it to do….
