Oil vs Grease

[SwellMel]

Just a question, I am sorta new to this and I have been cold screening my raw oil that I collect through 100 micron barrel filters, this catches the grease and I just scoop it out and put it back in the carboys I get the oil in and throw it away, as it gets colder in my garage this is taking longer and longer to pre screen. Do any of you use the grease too? I heat the screened oil to around 200 degrees and then filter through 2 whole house water filters I got from Lowes, the first one is 20 microns and the second is 5 microns, then to the truck.

I use the animal fat. IT burnes nicely. Makes fitration a little more challenging but i deal with it.

So you use not only the pancake syrup, but the applesauce as well as the peanut butter too

I've been throwing away the thicker stuff, so this afternoon I started using a 110volt bucket heater for the prescreening. It cut down on my waste on ten gallons from around one and a half gallons of sludge to about a quarter cup of trash.

the apple sauce is about the worst stuff i see...no peanut butter but if it melts when i heat it, i use it.
I also use a bucket heater to warm the oil before prescreening...makes life alot easier.

I used to avoid the sludge animal fat, but here lately I've just been dumping it in.

I've got about 5 gallons of it sitting to the side that I need to buy a bucket heater for. I plan on warming that stuff up and pouring it in the still...

Indeed! Well said

Try adding an extra barrel on you filtration setup. Stretch some screen over the top of it and clamp it securely. The applesauce will go through fairly easy. Use a band heater or whatever and heat the entire barrel. Pump the hot oil out and through your 100 micron stainer, and it will go through nicely.

I don't see any method for dewatering the oil described here?? There is no reason to hit 200* prefiltering EVER, imho. (I shoot for 110-120*, then settle 24hrs or so and drain off any previously emulsified/suspended water). Also, water filters can allow particles MUCH larger than their 'micron rating' thru. They are "nominal" rated filters. Make sure somewhere in there you are using a 'fuel filter' with at least a 5 micron "absolute" rating.

As an aside, I found water filters were not very economical if they were actually filtering anything. For a looong time, I had just a couple of sources and the WVO was very, very clean and often settled for weeks before I filtered it. The water filters lasted a long time (there was nothing to filter!). I now collect ALOT more oil and cannot be nearly as picky and do not have the luxury of settling for as long before filtering. I use SS strainer basket (cleanable/reusable) about 100 microns for initial filter and a series of fuel filters after - 30mic, 10mic and 2mic. So far, much more economical AND much higher flow rate without danger of failure due to heat. (the water filter housings/elements don't take heat, pressure and VO so good...) The water filters were only $2 ea, but either plugged up or structurally failed (changed shape and allow dirty oil past) after just a few gallons.

I recently put all the stuff you described as 'throwing away' in a drum and heated and settled it. 85% ended up being burnable oil (and animal fats). The problem can be getting this stuff to the truck tank (must be warm to pump) and then out of the VO tank on truck at switchover. If the oil is not liquid and the whole tank is heated, it may take longer to get the oil near the fuel pick-up warm enough to be sucked out... (I have 'extreme heat' in both of my conversions, so the THICK stuff is no problemo ) In fact, I often take the PHO and high-fats oils other conversions cannot use and used it in my junk!:chuckles:

I get the fuel filter heads for as low as $10 ea and filters as low as $4 ea. Its hard to beat the 10 mic Golderod-style filters ($4ish elements at tractor supply). Don't bother with the (more expensive) water-block fuel filters, they will not stop water in VO anyway...
