Eduardo:
Hope you are ok.
We have all taken a spill or two
in the shop ! I know I don't bounce like I used to. Roll Eyes

Your shop looks great, lots of room .
How long does it take for the tote to empty through the shavings to the bottom
tote? I like to let our fuel sit in the chips for a day or two and cycle it around periodically.
Residence time is good. I really like the upflow design, please let us know how it works for you.
I worry about leaks on the top of the drum.
Your de-meth process looks solid to me. Once the fuel gets hot the fan will pull the methanol out.
Make sure you are out collecting oil while that process is running.
Good Luck
regards
Tom

Thanks Tom.

I have never used chips before. So thats my concern.
Im planning on letting raw demethed bio settle on the pine wood drums for 48 hrs at least.
Then drain the resin from the shavings.

After that; im planning on letting the bio from the upper Tote flow thru the drum slowly (2-5 lts/min) So if the average flow rate is 3.5 and the Tote has 1000 lts it would take aprox 5 hrs to pass thru the chips and to the bottom Tote.

Is this flow rate doing any good? Should i go slower?
Bio has been settling for a week after demteth.

I wanna try to prepare my shavings with bio tomorrow.
Any advice would be appreciated.

Eduardo.

Nice job Yuka!
Hope your OK.
I let my chips set for a week or more to prepare them, if I can, then I run fuel through until it comes out clear. Usually takes about another drums worth of fuel before it comes out nice and clear.
I use a metering pump in my setup, it has an adjustment for pressure that is set so it wont pump over 2 PSI. At around 3~4 PSI the clamp on plastic lid on my chilled upflow drum will weep fuel out around the seal, below that and it doesn't leak at all. My 55 gallon steel chipper drum with the bolt on lid ring doesn't leek at all, even at high pressure (I actually domed the lid up on it using compressed air to blow out the fuel before changing the chips once and it still never leaked around the ring).
The longer the resident time the better, I do single a single pass over the course of at least a week per full tote of settled and clear fuel.
Cheers,
Jon
metering pump

chilled upflow drum, you can see the edge of my domed 55g steel chipper drum on the left..

Jon, thanks!!
Damn men looking good, nice Job on the fridge.
Son what do you usually do with your bio (the one you drain) that was used for preparing the chips?
Is it one week neccesary?
As i gravity feed it, whats the recomended flow rate to go thru the chips.

Thanks.

Bio has been settling for a week after demteth. Quote:

There are a bunch of different ways to get to the same place.
I think residence time is more important than flow rate but
all of the fuel making processes respond favorably when not
pushed or hurried.
After Demeth and settling do you see fallout that looks like pancake syrup ?
If you do then your demeth process is working. Once the MEH is gone
there is nothing to hang on to and it drops right out.
We call it true soap and we mix it 1/2 and 1/2 with BDG and call it bar oil for the chain saw.
Leftovers go in to our industrial soap.

I guess we are really lucky here as I can get kiln dried hardwood shavings and
resin is not an issue.
Cold Upflow looks pretty Slick Jon Wink

Tom

I put it directly into my my shop furnace tank. Other people reprocess it with their next batch.

I have no idea, thats just what I do to give me some piece of mind. I dont use pine either, I use kiln dried oak so your mileage with pine may vary...

The slower the better. Just do a shakum up test or soap titration on the fuel coming out of the chips, that will tell you definitively, if its slow enough or not...
Thanks.

After 24 hrs of settling the bio in the drum.
I took a sample from the bottom and did a heavy water shake test.

Left sample (small one) it was tooken and water shaked 4 days ago.
It has a little middle layer. And the water is literally milk.
Right sample is the sample tooked from the bottom of the pine shavings/sawdust drum, settled for 30 mins after a pretty heavy water shake.

What i found interesting besides that clearly it reduces soaps levels, its that it doesnt have a middle layer at all (pine wood resin).

Any idea? Ill take a sample tomorrow see how it goes.

So far so good.

Saludos.

I would start continuously feeding the bio through, in down flow, until the fuel starts coming out the bottom crystal clear, then switch to upflow and try the shakemup test.
In my experience with un-softened well water, the water will appear clear with no soap after a standard shakumup test if the chips are doing their job.
If you shake too hard it will take forever to see what you have, just turn the bottle over gently 4 or five time to mix it, you dont want to pulverise it.
Cheers,
Jon

Hey Eduardo,
the sample on the left appears normal except at the top.
Does it have a small layer of dark on the top? The fuel looks good,
the white milky is normal after a water wash. the more you wash it the clearer it will get.
Did you do a 3/27 or other to test your fuel before you washed it ?

Hey Jon , Fuel looks sweet !! What type of oil did you make that batch with ?
regards
Tom

Thanks Jon.
Thanks Tom.

Nothing at the top of the left sample.
Te right sample has no emultion at all and relativelly cloudy water.
The bio looks cloudy because the pic was taken 20
Mins after the shake test. And the container is of plastic.
But if i take a sample of the right pic Biodiesel y assure you color is even better that the one on the left.

Im still letting the bio stay in the drum.
Because im still preparing the chips.

Ill take a sample today. And post a pic.

Thanks.
Good day.

Eduardo.

Left sample, water shake test 5 days ago. White water and little middle layer. But great looking bio on top.
Right sample, water shake test of today.
Bio has been settling in the pine shavings/sawdust barrel for about 48 hours.
Water is really clear after heavy water shake, but the Biodiesel seems cloudy.

Is this because of the resin on the pine shavings?
Im gonna let the bio sit until Monday so its about 120 hours of residence time for prepping the shavings.

Of curse i will be doing more test with the drained bio.
To see how many gallons i can use or to definetly drain it all.

Can i reprocess that drained bio normally?
Mixing it with some WVO?


Have a good day everyone.
Thanks.
Eduardo.

Looks good! It's cloudy because it is wet. Water washed biodiesel looks like that before drying it.

It looks ready to go to me, I would switch to upflow now. The water makes the bio cloudy as suggested.

The resin settles to the bottom and will look like clear but cloudy oil, in my experience.

Yep.

Thanks binuya and JON.
Im going to the shop in about 2 hours.
Will post some pics.

It really seems a good pre-filtering method for longer resin life!
Wonderful so far, and with pine shavings.

Good week friends!

I came to the shop today and took a picture of a sample we took 3 days ago from the bottom(drain) of the wood chip barrel.
I notice really clear bio on the top.
But there's a creamy stuff in the bottom.
Notice that i took the sample from the bottom drain of the woodchip barrel.


My question is.
Is this the wood resin?
Or is it soap settling?
