Howdy,
Nothing new really but a timely reminder for established and pointer for new members.
Pre shroud:
Boiler: 50lt SS keg
Heat time: 1.25 hours
Wash:48lt
Run:2 - 2.5 hours
Gas: 3 burners rings used
With shroud
Boiler: 50lt SS keg
Heat time: approx 37mins
Wash:48lt
Run:1.5 hours
Gas:small ring and large ring on half
Cost $17 for drum (Paramounts if in SA), cutting disk existing, scrap R2.0 90mm Earthwool, Selleys liquid nails super set $7...should pay for itself in 2 gas bottles time :D
simple, quick saves you plenty. 50lt kegs are about 370mm wide, drum is 600mm insulation 90mm so 600 - (2 x 90mm) gives you a nice comfy fit. Won't worry about heat loss this winter.... as a guide I'm about to do spirit run 6 from same 9kg bottle. Tested with MAPP Pro 3700c+... flat stick with air hose flat can just induce smoulder but no ignition....bottle gas or even car LPG about 1900c so well good.
This is it after a few runs... good as new...
So now you have your winter keg cosy...get on with it and save ur self a few $ :handgestures-thumbupleft:
