treatment of WVO pre settling

Postby denson » Mon Jun 02, 2008 9:53 am

I was wondering if anyone has tried treating WVO with various chemicals or thinning agents prior to settling. If so, what were your results, and what treatments or additives did you use? Also would thinned out WVO settle faster than raw WVO?

Yes, it would settle faster when thinned but I prefer to keep my oil processing "food grade" so I use very even heat instead.

The trouble with thinning or most chemicals is that it makes the hot pan test not work any longer so you will never know if you got the water out.

Also, some thinning agents, like alchohol, will prevent the water from settling out.

Another think to consider is that those inevitable spills on the ground would be toxic (and not biodegradable ) unless the is a natural product like turpentine .

The only chemical I ever add is the biocide Killem.
I have found it to have ZERO effect on hampering water removal.
I pass the HPT 90% of the time on the first go around.
If I fail I repeat heat and always pass on the 2nd time.
