Re: uncut copper tube the same as rasching rings??
- I was able to control the system by adding or removing insulation to
the bucket lid. Fully insulated with 350W heater 4 meters of tube was
hot and the end was warm to touch (this is with air cooling). With
uninsulated lid 3 meters was warm. It should work pretty well for
sugar mashes but malt mashes are the problem. If you have enough room
start with a straight pipe that has downwards bend at the middle.
That way you can adjust reflux/output rate by moving the bend (use
gloves though). You can make it a compact double spiral or something
similar for the next run. Watch out for leaks though, I had to use
flour paste to seal the lid to the bucket (real PITA to clean
