Who's using 80 gallon appleseed?

Anybody on here using an 80 gallon appleseed setup?? I just switched my 40 out to an 80. IF my calculations are right, I shouldnt have to change my wash or dry tank. Both are 54 galon drums. Now I process 100l batches and get 22-24 galons finished fuel. With these numbers, I should produce 44-48 gallons with a 200l batch. I wont be able to mist as long in the wash tank, but I can run a few more cycles to accomplish the same goal. Anyone else been this route? Thanks!!

sorry, you lost me at hello (but i didn't want you to think you're being ignored)

I have read of people needing to increase their processing times when using the HF pump because it does not flow enough to properly mix the batch. the first few you do, I would do a 3/27 during the process till you pass. It may take a few hours of mixing to push the reaction to finish. play with it and let us all know what you find!

I am just in the process of building mine. I have an 80 gallon HWH and figure that I'll probably make 60 gallon batches. With Meth and KOH I figure that will pretty close to fill up the HWH. I have looked at a couple different solutions for washing. I could split the batch and use 2 55 gallon wash tanks. I have enough 55 gallon drums for this but space is getting to be an issue. I am also considering cutting 2 55 gallon steel drums and welding them together to make 1 90 gallon drum or there abouts. I am actually considering doing that to make 2 90 gallon cone bottom tanks. One for pre processing before going into the HWH and one for post processing/settling, that way I can keep things moving. I haven't settled on a final yet.

I may be totally wrong, but I dont think you will ever pass a 3/27 while processing because you havent let the glycerin settle out. It is still being mixed around in the batch, and is going to show if you draw a sample before the 24 hour settling time is over.

60 gallons may be pushing it I think. The most I read you could do in a 40 was 100liters(26.5 galons), leaving room for 20liters methanol(20% appr 4.5 gallons)), and 5% water prewash(6liters/1 1/2 gal appr) adding up to pretty near 32 gallons of liquid in the processor leaving a little room for mixing. Heck, now that I look at the numbers, it may squeeze in and leave some room for mixing. I am interested to see how it works for ya. Good Luck.

I have never done the 3/27 during processing but according to the bio community you can
The 3/27 Conversion Test - Collaborative Biodiesel Tutorial

What can the Warnquist 3/27 Test Tell Us?
....
Monitoring your process: The test can be used in mid process to determine how long to run your reactor, or monitor your conversion at different stages in the process.

i guess you would need to let it settle out for a few minutes and draw from the top before you put it in the methanol.
