The Still Spirits 25L Reflux still

I picked one of these up a while ago since I have absolutely no construction/engineering skills at all to build my own and was told that these are fairly decent stills.

I had it working ok with my first few distillations with around 3-4L of distilliate coming out around 76-78% off a 25L wash. I'm a bit of a perfectionist so 76-78 was nowhere good enough and I decided the still needed some modifications.

I noticed my biggest problem was keeping the temperature down around the 78-79 celcius mark since the hot climate here on the east coast of Australia means that I have to run the water at a few litres per minute (rather than 400-500ml as recommended), however having the water running this fast puts too much pressure on the hose connection and I usually end out with a garange full of water from the hose popping off the connection before I can get the temperature down to where I want it.

I tried fixing this problem by freezing some water bottles and throwing these in a bucket of water and then running the hose through the icy water but this only helps so much. I'm currently having to run the still at around 80-81 degrees. If anyone has any other ideas to reduce temperature further I would love to hear it.

The next thing I tried to improve was the packing. I changed the marble for some cheap stainless steel scrubbers I picked up from the supermarket however I only managed to get maybe an extra 1% alcohol compared to using the marble. Should there be more of a difference or is the packing material fairly irrelevant?

I want to change to the Super reflux as this has a wider column (not sure about height) which would allow for more packing but only if it increases the alcohol content enough (increasing by 1% isn't worth an extra $250 in my opinion). I have also seen a still extension that I believe is simply a screw-on extension to the column which is supposed to increase the content to somewhere in the 90's. This is a definite purchase a bit later down the track.

Anyone have any other tips for improving the Still Spirits still? I've tried searching but I couldn't find much information.

Also, I posted about using the Still Spirits still as a pot still in another thread however nobody has replied so I'll ask it again here. I found the page below on the Still Spirits site and it explains how to change their essential oil extrator between being a pot still and a reflux still. I'm pretty sure the essential oil extractor is the same as the 25L super reflux still but I thought I would check here first before I go disconnecting hosing and blowing the thing up.

Thanks everyone! Any replies would be GREATLY appreciated

First, yes the two stills are the same, so go ahead make the changes.

Second, try using a desktop fan facing the condensor as this will increase the cooling effect. You can improve the efficiency even further by having the fan blowing across the top of a roasting dish of water with ice in it (more surface area). The wicking effect will act like a crude air conditioner and should allow you to reduce your water flow considerably. Good luck. :wink:

Hi, I too was unhappy with the out put, T tried packing the column, it flooded and chocked allowing vapour to escape fron the lid seal.
I have since made a voltage controller using the plans in in this forum.
I am now able to collect 83-85% then temp rises into mid 80s c xnd I collect tails to redistill later.
Hope that helps Newts.

Buy some hose clamps - or build a better still - save the hose clamps - you'll need them on your better still.
