Changing from a single batch 1 vessel system to a double batch electric 3V rims system. Have all the pots/plumbing but not the control box or the electrics. Out of four kegs only 2 left with about a jug or so between them so decided to try it out today.
Can use my 1V control box as it has ramp/soak pid and pump control. Heated up sparge water in urn first as it's insulated then switched to the mash tun, only had a cheap 10A plug to wire the 3600W rims to... Was only doing a mild so should be OK.
Water up to dough in and the plug already drooping and smoking. 30 mins at 69 then 10 at 72 and78. Started pissing down, rig out in the open. Quickly drained the MT and got the sparge water in the MT and ramped up the pump speed a bit to quick so compacted the bed, went and got my sailing wet weather gear on, stirred the mash up and got things flowing nicely. Turned the rims tube back on again, got out of the rain after covering the control box and pump. Checked after 5 minutes and temp has dropped, checked plug and melted.Started transfer to kettle, still pissing down so get pump running hard...compacted again. Eventually got it into the kettle. Was going for 72% eff, ended up with 85% into kettle so that's good. Still pissing down so decide to bring kettle just inside. Pot and 55l of wort bit of an effort to get onto my wok burner, but really good boil. Kettle will be electric when finished but the rambo burner boiled it easy, plus they are awesome for wok cooking.
As I was already over gravity decided to make 2 beers instead of a double of mild. 60 min addition was 20 ibu of styrians, put bit over 2 litres boiling water into cube with 1g/L styrians and filled cube. Boiled the remaing wort till 10 points higher than the mild and drained into cube with 1gL each of cascade and citra. Might dry hop some citra in that one too. Fermenting mild with 1968 and will try the BRY-97 in the other, will be interesting to compare the 2.
Need to insulate the MT and kettle and finish the control box before the next try out.
Pretty happy though, clean up was easier than the single rig too I think.
