@Admiral Toad, let me see:
- The size/power of the heating element mostly depends on the used boiler. With our 50L Milk Can and one 5500W element it should be no problem to drive a column up to 8 plates quite hard. The real power is just needed for for heat up, during operation you would reduce power enough to keep it going at a reasonable take off speed (like reducing from 5500W to let's say 3000W, that's where your DIY Controller Kit comes into play).
- Output per hour is quite individual with a reflux column, because the slower you take off the more water you give the dephlegmator and the higher the ABV. A typical number could be 5 L/h with a 10% boiler charge at ~90% ABV with 4 plates and regular (mini) bubble caps (at least 20% more with ProCaps), but such results vary a lot depending on user.
- Here in Austria one is only allowed to have up to 3 plates, so yes, you can go from wash/mash directly to end product, which is the typical use of a reflux column, but of course that depends on the desired product (as known there are worlds between let's say distilling whisky and vodka).
- Water flow is another point of large variations because it depends on intake water temp, desired product and take off speed. I wish we had more user feedback, because if I tell that one uses 12 L/h at warm ambient temps it's like telling a house number.
Please be aware that due to legal reasons we can not use our equipment ourselves here at our office/warehouse location in Austria, so we may not be the best source of information concerning usage. For that we have our
StillDragon Community Forum with actual users around the world willing to provide all the desired info. It really is a very friendly place and I'd like to encourage everyone interested in StillDragon equipment to have a look and sign up there.
