water removal

[TomThomas]

has anybody found a way to effectively remove water form "oil" (no matter what kind), besides heating? thanks,Tom.

Go look at one of these; Simple Centrifuge ... putting a centrifuge in every garage!



That will do the job for you.

centrifuge

WOW



I have wanted one but the price told me no you can't



this might just be the ticket



thanks for the link... ... Mundgyver

Your welcome

Heat is really the only way. You don't always have to boil it though. The emulsifyers added to frying oil tend tend to lose their effectiveness around 140F. Use a tapered drum with a heating element in it. At 140F just drain the water off the bottom, then you don't have to boil it out.

thanks for the replies. I kinda had a feeling that heat was the only plausible way for me, but I was hoping that maybe there was something else. That centrifuge thingy is pretty cool, but I don't have any idea what it does or how it works. Tom.

Water is heavier than oil, hence oil floats on water. A centrifuge will give you the ability to create an artificial gravity and spin out the water and solids, thus allowing you to clean the oil. Depending on the dwell time of the oil you can actually clarify it. If you have several hundred gallons of sludged oil, you can heat it up just prior to putting it through a centrifuge and separate the oil from the water and other contaminates. You can also spin the soot out of oil using one.

That is great information, did not know such existed. I still cannot figure out how it works exactly, must you pour in a gallon or so at a time or is it a little more self feeding than that? How for instance would you go about cleaning up 50 gallons of fry oil with it, anybody know?

You start up the centrifuge and then trickle in the oil though a metering valve. The dirty oil goes in say at a rate of 1 gallon an hour steady state. It will come out at the same rate but will be cleaned and ready for use as the dirt, water and other contamination will be trapped on the sides.



If you have 5 gallons of oil to put in, make sure you have a 5 gallon container to catch the clean oil. Start it up, set the flow into it and then go do something else for a couple of hours.

stuff

Centrifuge spins at high speed the oil is fed in to the middle of the drum.

The drum will hold some oil that will never be able to be processed the heaver stuff in the oil,chicken parts,sluge,water anything heaver wiil be forced deeper in to the oil that is spinning. the oil that is clean at this point will flow over the edge of the spinning drum and will fly to the stop wall of the centrifuge this is the outer wall and it is collected from there.



The drum needs to be cleaned this depends on how dirty the oil is. The one they have has holes in it.



The only thing about this that might be a little scary is the fact that if you are spinning say 4 lbs of oil and the drum its alum so thats good at the speed of the motor thats 1750 or 3450 rpms the force of this is high. The maker says that it is 1000 times more than gravity. so 4 lbs turns in to 4000 lbs and so on. this is not something you want to take lighty. (no pun intended) :-laf





As far as doing 50 Gallons this can be pumped in to the Centrifuge or gravity flowed in to it the later makes more sence to me using a 55 gallon drum and a ball valve to only flow in say 5 gallons per hr taking 10 hrs to clean 50 gallons of oil. I am sure it can be done faster but remember safety first. Thinking about this overlunch maybe two of them side by side might just be the right thing to have.

just make sure you have a holding tank for the oil you are about clean !!!!!!!

OK, thanks guys, I understand now.
