Hi again guys! I picked up some 50 gal plastic barrels. I want to prefilter my fryer oil while pouring into the barrels. My question. If I used the 5-1 Micron Trade Size 1 Large Filter Bag and cut a hole in the top of the barrel say, a 1/2 inch smaller then the ring on the bag. Would the ring on the bag hold the filter from falling in the barrel? Also...would that be the right filter micron size to use for that purpose? Thanx in advance! Vic
I filter mine by pouring off the top of the cubies after they have settled for a couple of weeks through 200 micron bucket filters into 5 gallon Homer buckets from HD. I then pour that filtered oil into a 55 gallon holding drum to settle for another week or 2. In the beginning I would get a bunch of filter bags and filter down to 1 micron from that drum into a 55 gallon drum below, then repeat the process a second time. Recently, I finished building one of the juicer centrifuges, so I have gone straight from the 55 gallon settling drum through the centrifuge into the lower 55 gallon drum. I was hesitant at first as to whether I was getting anything so I pumped the filtered oil back up to the top drum and then ran through a single 1 micron filter with ease. That's just my setup and the small filters in my VW are lasting around 7K miles before they start to clog in the winter. My fault for switching to WVO too soon before everything is hot, but $2.50 for another filter is chump change compared to the $4.15 per gallon for diesel here.
I would imagine the ring on the filter bag would hold it up as long as the hole is smaller. However, 5 microns is far too fine for "pre-filtering", unless you're getting extremely clean wvo, even that's a stretch, especially if it's unheated. You're just going to end up clogging your filters real quick, if the oil even gets through. I highly recommend getting yourself a couple EZ strainers (Amazon sells them, or just google it). They fit perfectly on top of a 55 gal drum, and you can stack them on top of each other.
I use a 400 micron EZ strainer stacked on top of a 200 micron EZ strainer. I pour the oil straight from the cubie (usually settled for 2-4 weeks) through the 400 (which it goes through no problem, it serves mainly to catch the big chunks if there are any) then it goes through the 200 micron strainer into my 55 gal drum. For my oil, 200 microns seems to be the threshold; it takes a while to strain through it on its own, so I usually coax it through with a plastic spatula which is a huge time saver. I say threshold because I also have a 75 micron EZ strainer, which I have stopped using because once the oil gets through the 200 it flows right through the 75 micron without much residue left behind, so I stopped using it since it's just another thing to clean.
From there I heat up the 55 gal drum and pump the oil through a filter housing containing a 5 and 1 micron bag filter and call it good. Ideally, I should let it settle in the drum for a while, then transfer it to another drum through a 10 or 5 micron filter, then filter it down to 1 micron, or even better would be to centrifuge it. But so far so good, in the future I may upgrade to something a little fancier, but this serves my needs for now.
I should add, if you’re trying to go super low-tech, easy-and-cheap-as-possible, a friend of mine filters his oil the following way: gravity feed through a 100-micron size-1 bag filter (hanging) into 55 gal drum, transfer pump up to gravity feed through a 5-micron size-1 bag filter (hanging) into another 55 gal drum, done. He has a TON of oil, so it probably settles quite a bit before and after filtering, and it’s also straight from the fryer so he claims heat is unnecessary as it is already water-free. He also drives an old beater Mercedes that’s worth much less than an elaborate filtration system. That being said, I’ve burned his oil (~10 gal) in my TDI with no problems.
What is these "Micron filters ""
Are there special filters or are they something you can buy just abour anywhere .
I read bag filters ... Drum filters .. Filters with a ring on the bags etc .
I did maple syrup as a kid .. and the guy used a 100% cotton sheet fasten to a 45 gallon drum with a pile of clothes pins around the rim of the drum .
I am assuming the different filters are for each different use or size of container .
Or maybe you can buy a filter for five gallon pails and a filter for a drum etc .
How is oil from a fryer that has been cooking stuff with water content going to be "water-free"? If settled and pulled from the top, then okay, but not by virtue of just being "straight from the fryer."
Water free around here is. Sometimes water free and sometimes the person cleaning the fryer rinses it out with hot water . Then there is water in the oil .
With the fact that water is not a good thing in the fuel I believe most if not all oil should be dewatered so to speak . Plus I can see where the fines should be kept out too
