Wet WVO

I am trying to de-water some oil from a new source and can't get it right. The oil is from a bar that frys a lot of wings and frys. Ran it through my normal process twice and it is better but still have large bubbles with the HPT with minimal audible crackling. My setup is like Clay's and I usually let it settle after being heated for 2/3 days (Whenever the temp. drops to around 100). It may be more trouble than it is worth but I am on a mission to figure it out. I don't have to have this oil but it would add a little surplus to my supply for extra road trips. What do you guys think - more time to settle out or do I need more heat? Any other suggestions?

How hot are you getting it prior to letting it settle??? Get it to 120 - 130 ish and let it settle overnight, drain from the lowest point and test it. Should be good, if not drain off a little more and test again. But hold on I am sure one of the "experts" here will chime in soon. I am just a dumb Fireman.

This might not be an option, but I had oil that my dad had sitting in sealed 55gal drums for 10 months, and it was perfect, I didnt filter/dewater one bit of it, it just settled out and we pumped the top 85-90% out of the barrels and use it.

Second method, would be more heat, at least 140F

But mine has zero water ( no bubbles in the HPT) or I heat again until it is bone dry.

chances are you didn't drain off ALL the crud. Heat to 140, settle at least 24 hours and drain off 5 - 6 gallons what you drain off can be left to settle in whatever container you drain it in then you can suck off the top 3/4 of that to use again.

I have been heating to 150, settling for 2/3 days and then draining off 5 gallons (back into the cubie)? I reheated it yesterday and was going to let it settle for 4/5 days but do you think I just need to take more off the bottom? I have noticed that what I drained off the fist time settled in the cubies after a few days. Bottom looks milky and top is clear.

If you have heated and settled this batch more than once and your still getting milky stuff out, you would need to settle it longer i would think. I would go ahead and run it through the filter once and then heat/settle again and maybe let it set for a week.
Sounds like some really wet oil and when you pump it you created a huge milkshake. It will break eventually, just hard to guess how long. If you have oil like that in the future, its best to leave the cubies setting for a couple weeks and then suck off the top only and stay out og the milky stuff in the cubie.

If you are getting some milky stuff, like it looks white, you may also have a partially hydrogynated oil and thats what may be on the bottom. Are you getting the oil in cubies or out of a barrel? Look at what the box says that it came in if you can.

I get in in cubies. It is not hydrog. oil - pure Canola. My other oil sources are bone dry and cleaner than clean. The one place just frys chips in their oil and the oil looks brand new when they give it to me. I will let this batch settle longer and report back. Like I said I may pass on this oil if it turns out to be too much work to settle it but I want to see what it will take to get it done.
