Indoor cooling drum setup

[Frothwizard]

I've got a 750 Watt submersible cycling through 200L of water in a Pickle Drum.

Squirts water out of the lei-big like you wouldn't believe. Not strong enough to break the copper welds though.

I have a 30l ss reflux and I've found slowing the water down to about half litre a min cools it better. Am I imagining things and running fast does the same job?

When I was a full time T-500 person, with the typical cooling temperature problems, trying to confine it to the second distillation temps of 55/60 degrees Celsius for optimal quality and purity, I had to use two 60 litre water containers on a (Y) connection two valve connector to the Colum. (ALL new) I used each 60 litre drum for only one hour, then switched the pump and valve over for continuous flow, with very little temperature variations. If it was a hot day, on every hour for each 60 litre drum I would introduce two kg of ice (It does help). If to only use one 60 litre drum, after two hours the water temp is to high and you loose the margin in the regulator. (Your fucked). Two tanks with fucking around is better than average alcohol. I'm glad I've move on to bigger and better things and using grains. The journey continues using a fractionating still and of course cuts, which makes sense.

Not sure but I know that there are different flow properties for fluids at different speeds. Up to a certain flow rate water will have laminar flow through a tube where a layer of fluid adheres losely to the surface while the rest rushes past. Go faster and you get turbulent flow throughout the entire cross-section. Perhaps what you're seeing is the difference between turbulent flow and laminar flow in your condenser. I'm guessing then that laminar flow must be better for heat transfer. I did study this stuff years ago but I haven't had to use it since 1999. Surely someone will correct me if I'm wrong.

Can't see the pics either :crying-blue: And mac was it my imagination or were you promising a fancy bubbler plumbing run down some weeks back :pray:

I was thinking two 190l olive barrels (I can get em cheap) n just pumping from one to the other. Keeping the feed cool and even then just pump the hot water to the empty one, then vise versa for the next run

This was my old system on the kitchen bench, can't complain.

Dont need anything fancy mate, just a heap of water to start, then a pump, then a return route. :handgestures-thumbupleft:

Cheers guys, figured that :handgestures-thumbupleft: , but you never can tell when old mac is going to pull a rabbit out of his hat; case in point: Docs FSD Carter Head.:wtf:
Sometimes worth a look :D
