Re: New CCVM RC Upgrades, Having Issues with takeoff
When you are running a CCVM you can feel where the effect of the reflux condenser is greatest by feeling on the outside of the column where the sharp temperature gradient occurs. If you are in total reflux you’ll want this “boundary” to be at or below the offtake otherwise some place above the offta...

Re: CCVM flute problem, condenser fog, dissolved co2, cold weather...need yer thoughts
I’d be interested to know whereabouts on the outside your column that you can feel the sudden change from hot to cold. Here’s my 2c, the hot vapour is hitting the really cold RC and suddenly condensing. This sudden decrease in volume in the column creates a slight vacuum at the top of the column tha...

CCVM may achieve very high purity product. They are cheap and simple to construct and easy to operate.

Re: In need of some advice regarding coolant system for still
A mate up here in FNQ uses a wheelie bin for his coolant reservoir. When the water starts to get warm he drops in some 3 litre milk containers which are full of ice. He’s running a beer keg boiler on gas with a 2” reflux column

Plenty of us here, myself included, have stories about bad things that happen, in the shortest time imaginable, when you are running a still. You really shouldn’t remotely monitor your still.

Re: Condenser Controlled Columns
Hey Berserk, how big is the offtake in relation to the column? If the offtake is the same size of the offtake you’ll get a minimum 1:1 reflux ratio, but if the offtake is smaller the minimum reflux ratio will be higher.

Re: Reflux condenser with or without SS scrubber
By all means weave SS scrubbers in and through the reflux condenser coil to maximise contact between it and the column walls. As far as other packing goes leave about a 6” gap between the top of the packing in the column and the lower edge of the outlet for the offtake.

Re: LM, VM, CM still designations.
When the RC is above the offtake, you can change the flow of coolant but the result is the same.

Re: LM, VM, CM still designations.
No, but you are changing where the reflux is occurring (in relation to the offtake). A similar discussion about the nature of the CCVM design took place in 2013 in the Condenser Controlled Column thread viewtopic.php?f=17&t=41579

The manual for the Kegland reflux still suggests output rates up to 1.2 litres per hour, assuming using the 1.0mm aperture restrictor

Re: My first reflux sac run
200 ml per hour seems very slow. Check that the orifice on the restricted valve is clear and that the breather hole is in the upright setting. Check that there is no PTFE plumbers tape obsctructing any of the connections.

Re: better cuts on a pot still ?????
Not sure I agree about not needing a power controller for T500’s on reflux runs. They can be a nightmare to operate if you have a fluctuating water supply and with no way to reduce vapour speed.

Re: better cuts on a pot still ?????
It sounds to me that there is too much cooling at the reflux condenser, try reducing the water flow to the reflux condenser.

Re: Need Help Building CCVM Still
Yes RC in highest position for maximum rate of output but minimum reflex. This assumes that your packing is at optimum amount, that the RC is knocking down all the vapour and that you are operating the boiler at optimum power level (just below the stage of flooding). You can increase the level of re...

Re: Need Help Building CCVM Still
gday Artooks, You need to increase the amount of reflux to get the higher ABV that you seek. If you want to have your RC wide open then you will need to increase power. Increase the power until you are just below the stage of flooding. The other way to increase reflux is to slightly lower the RC. Th...

Re: New VM Build...Can't get product out. Help?
Carefully feel on the outside of your column where the boundary between hot and cold is. That zone should be above the offtake. It is the zone where the majority of vapour has condensed.
