Centrifuges different types and prices$$

[greasyX]

The good,the bad and the funny.I started this thread for all of the centrifuge conniseurs out there,future and present.I'll go first,I have a Fryer2Fuel DieselcraftOC-50 set-up.This consists of a 108 gallon per hour centrifuge,Dayton Gear Pump,Barrel heater,transfer pump, and fueling nozzle.I set it up on a plywood framed cart with casters to be portable.Whole set-up was about $1350-$1400 delievered.This has proven to be reliable,and well built.Takes less time then any other type of filtering,with good piece of mind.I am very happy (so is the wife) with extra time for family.This time previously was spent filtering in the shed,Now its compact and in the garage.I suggest this for anyone who time is of the essence or in this case Grease.........grease out

Could you post up some pictures of your setup, with a little explanation of the process? I'm interested in going the centrifuge route once the V3 pays itself off

The concept behind the Fryer2Fuel system is great. If you don't want to mess with piecing your own system together and want to buy something "out of the box" (which I'm sure we all do if you own a V3), it's definitely a good option. But, for those wishing to save a few hundred dollars it can easily be built yourself in a Saturday and MANY trips to your local hardware store. By making your own, you can tailor it to your needs. For example, on the F2F system, I don't understand having two pumps. For myself, I just added a 3-way valve to pump from the drum to my clean tank or truck. I have a little less than $1000 in mine only because I purchased a new pump and motor from Grainger (equivalent to the one F2F offers) and using the OC-50 ($500). Could save even more if you try to hunt down a used pump.

Centrifuge Know-How

If anyone's thinking about going the centrifuge route, here's a thread on another forum that's a must-read. If you have a question, chances are it's already been addressed here:

I'll throw my hat in the ring for the bowl-type centrifuge. There are merits for either type and I am not sure you can clearly determine which is best. For what it is worth, I LOVE my SimpleCentrifuge home build.



Here is a link to a detailed description of my build:

http://www.dinofuelalternatives.com/DFAforum/showthread.php?t=102&highlight=simple+centrifuge

I put together the centrifuge for around $750 and the entire system (including the external regulated heat stack which I rely like) for around $1,000.

Nice system Fastcote. How many gallons through it so far?

Have you had any problem with the VO eating the heater element? The folks at SimpleCentrifuge seemed to think acids might eat away at it too fast....For a $200 replacement, I'd want to make sure it lasted a good while...

I've got a homebuilt system topped off by a Dieselcraft 0C-20. Like the V3, it's a little pricier compared to other options out there, but like the V3-you get your money's worth. Just FYI-the 0C-20 can't handle as much as the 0C-50 and as a result needs a smaller pump. I used this one:

http://www.grainger.com/Grainger/wwg/productIndex.shtml?search_type=keyword&QueryString=6NY91&x=0&y=0&operator=refineSearchResults&originalValue=Rotary&searchIndexId=1&typeOf=

My motor is a 1725 RPM 1/2 HP (it was just laying around) and hums along nicely when I set the pressure on the centrifuge to 90 psi.

Ditto on the valve setup Goon-I just have the output of my pump fed into a tee with ball valves on each end. By closing the valve on the left and opening the valve on the right oil recirculates through the heater, centrifuge, and barrel. By reversing the valves (once filtering is done) oil is sucked out of the barrel and sent through a Goldenrod filter (just in case any junk gets into the CF barrel) before going into the fill hose. This picture was taken before I added the Goldenrod, but you get the idea.

About 200 gallons so far ( I lost 50 gallons of that due to lye "boil out").

I am still playing with feed rates, trying to determine optimum. It is tempting to open the feed valve and let it rip - it makes a satisfying sound when all that oil is spraying against the sides of the pot. However, the longer it sits in the bowl the more polished it gets so slower feed rates are best.

The goal of the bowl types is to get all the junk in a single pass, but I am thinking of doing some recirculation like you spinner types do while the oil gets up to temp and to grab some of the bigger junk quickly, then switch over to a slower single pass to finish it off.

It is pretty hands-off so i COULD just slow the rate way down, let it pick up TONS of heat and let it go all day, but i can't resist monkeying with it. I guess I am still playing.!!

I haven't noticed any degradation of the heater so far. The thing is HUGE!

Did you try CFing it or did you just throw it out? I ask because SunWizard over at the infopop/burnveg forums has had extensive testing done on oil put through the Dieselcraft 0C-20 and he found that centrifuging will remove boil out.

[greasyX]

Wish I had known that a week ago,I shipped a barrel(55 Gal) off to the transfer station.Oh well next time I will just send it through the CF for 24 hrs.Does SunWizard Moonlight on here?Back in the day he helped me choose WVO over Bio-D,Explaining that it takes more energy to make than yield etc.etc.....grease out

I've never seen him around here but here's a link to the thread where he mentions it:

http://biodiesel.infopop.cc/eve/forums/a/tpc/f/159605551/m/7311068271/p/1

It makes sense when you think about the fact that boil out is a powder that has been dissolved in the oil-just like the microscopic bits of french fries and chicken finger breading. If you use a TDS meter (less than $20.00) you can be reasonably sure that your oil contains no boil out.

Could you please elaborate on dissolved solids testing and ranges to be sure of no boil out?

[Marv]

So could a person add a centrifuge setup into something like the Frybrid setup? Something like Clay and myself uses?

Seems like I've seen folks do it, but admittedly, I'm a bit confused on how the centrifuge would be plumbed into the system overall.

Anyone doing something like this?

[Allofus123]

The problem is the 3/4 pipe. Centrifuges prefer 1 inch pipe but it can be made to work. hehe

Follow SunWizard's thread and it will explain everything.
