SS Reflux Still
The distillation water saver will help me save on
water (money) as we are on a water meter, it's recommened
in the still spirits manual also. Just wondered if any one
had bought this pump and if any good. But seeing
that no one has I'll leave it at that. I'll take onboard what
you said about the hippo pump though.
Water meter! yes I did wonder if that was what it was all about.
As I say, I reckon that you could easily get away with a 225 litre barrel or two, and what the hell, don't pay for it, use rain water. Then as it's coolant, if it gets a big smeggy in the barrel you just add a little bleach to keep it fresh and top it up whenever it rains. after all, the coolant doesn't go anywhere near the wash or distillate does it,so you only have to keep an eye on the level, temperature and so you can control the flow rate, a tap in the "coolant in" line.
No point in buying some purpose made pumping system.
If you find that temperature is a problem, then just keep your eye open on ebay for a cheap, second hand bar chiller.
It depends what you're after Opus. I also still use SS triple distilled yeast, but I also still use the carbon as well. Initially, I'm aiming for purity, and quantity of recovered spirit i.e. I keep collecting down to about 60% for the hearts, but collect tails down to about 10% that go straight into the next batch of wash.I,ve been doing a fair bit of reading on the function and opperation of reflux stills in general. There seems to be two schools of thought on when you should start and stop collecting. One seems to be purely on temperature where useable stuff comes off from 78c to 92c and the other by ABV% stopping when its down to about 60%. In all cases we throw the first 50ml of a 20L wash as this contains methanol the bad stuff. With both these methods we produce considerably more volume than the 3L suggested by the PDF published by Still Spirits for their super reflux. So I would be interested in what others are achieving with their stills. I'm still using sugar wash with triple distilled turbo yeast although I omit the turbo carbon.
Once I'm happy with the purity, I let it down to 40% and re-distill, hence I get about 3.5 litres at 80 to 85% from the table top. I've yet to try it with the reflux still, as I'm concentrating on making an "easy connect" system for my water supply for the condensor, then I'll probably run it with cooper mesh in the reflux chamber.
My goal being the magical 95.6% though if the SS super reflux won't achieve that, not to worry, as a friend found me a "good nick" 9 gallon stainless barrel and I've been reading up on column design over at homedistiller. I know where I can get most of the copper parts, it's just a decent needle valve thats provong a little elusive at the moment.
