From a 25 liter wash at 14% Alc (usually a sugar wash from 6kg of sugar and Turbo yeast) you can expect about 2.7 litres of 95.6% ABV. With the column packed with Stainless scrubbers you will collect at at rate of 500ml/hr and with the column packed with SPP (Spiral Prismatic Packing) you can collect up to 1200ml/hr. Cheers.
Hi Erwin. Thank you for your comment. If you read the hundreds of posts on distillation forums (like Homedistiller and dozens of others) about "safe" materials to use in the distillation of alcohol you will see that it usually ends in a stalemate or a stream of insults and nobody can agree on any safe seal to use in the distillation of alcohol. I think the only "safe" thing they can all agree on is FLOUR PASTE!! I think it is all a matter of managing the risks and how much risk you are willing to take. I distill 95.6% Alc many times a month and I only use EPDM (ethylene propylene diene monomer) seals. I have tried all kinds of seals (including PTFE and silicon) and I find the EPDM seals the best. I have used PTFE seals and silicon and haven't had any problems with them. The problem everyone is concerned about is the leaching of poisonous chemicals out of the seals and into the alcohol, BUT we (conveniently) forget that the most dangerous chemical in the whole process is the ALCOHOL!! Anyway, the way I try to minimise the risk is to take a new seal and soak it in 95% alc for a day or two and then use the seal in a few strip runs on my pot still. By then I hope any "nasties" that were in the seal would have leached out and I am willing to take that risk. In a 50mm seal (uncompressed) there is only an area of about 2.25cm² exposed to the alcohol and soaking in 95% Alc and using the seal in several strip runs will certainly get rid of most (if not all) of the things that can leach out of the seal. Happy distilling. Louwrens
@@LouwrensvanderMerwe Thanks for the indepth answer. I do agree (as a chemical engineer - by study) that the ethanol is the main risky ingredient (but I must confess I do drink very little, 3-4 shots a month...). As I don’t distil that often I was just curious how silicon, ptfe or other seals will behave after some 10+ runs. The amount of additives extracted from the seals by ethanol is really low. We did some GC analysis after heating seals in 95 vol% alcohol under reflux at boiling point for 5 hours and some ppb of some additives could be measured, but our ethanol contained more impurities by itselfs...... So I don’t care about the additives, but am more interested in if seals get mushy or bittle over time. And flour seals? Bit difficult when using 2” piping with flanges 😜 I’m expecting 5m 6mm copper tubing for my condensor as for column distilling my 25 cm 6 pipe condensor from Uncle Ali isn’t giving sufficient cooling with my reflux ratios.....
@@erwinamesz7642 Hi Erwin. Thank you so much for all the information you've added to this discussion, I find it very interesting and helpful. I have never had a seal (PTFE, silcon or EPDM) get "mushy" on my, BUT The EPDM seals do get brittle after about 2 years of constant (twice a month) use. Cheers.
You can theoretically do it in any size tube, but 2" is the most practical. Yes, 80 + 20 by 42mm should work. Try make the 80cm a little bit longer if you can - closer to 85. Cheers.

Thanks for the video!
Please mention the quantity of high proof spirit than can be collected in an hour or any such data.

Hi Louwrens, just a hi from The Netherlands! I use PTFE seals but also have silicon seals at home. Any remarks/thoughts?

Это будет работать хорошо!
It does. Produce 95.6% alcohol. Cheers
Hi,
Can l do it 80 cm + 20 cm pipe lenght and 42 mm widht..??

How can I order this
