What happens when a group of engineers take brewing too far...?
We have been brewing on a two tier three keg system for quite a while and found that 15 gallons isn't keeping up with everyone's kegerator, so a batch size upgrade started becoming necessary. We elected to use these pots:
Mash tun: 25g
Hot liquor: 20g
Boil Kettle: 45g
The hot liquor tank is also the herms heat exchanger. We have access to a tig welder so we are adding all of the fittings plus thermocouple inserts to each of the vessels. The mash tun is also mounted on a rotating shaft for dumping used grains at the end of the mash.
The boil kettle has a hop filter and whirlpool attachment for use when the pump is circulating through the plate wort chiller.
We mounted the boil kettle and hlt on hinged platforms that rest on electronic load cells for water dispensing and volume measurement. The intent is to get the system running on labview software after we get the hardware up and working manually. We have a bunch of solenoid valves to buy...
More to come....
