Hi folks,

I hope I didnt miss this if my question was covered in this thread: in the summer time here in Southern California, my garage is way hotter than the ideal 65F that has been stated for the most ideal temperature for the cold upflow method. Will this be a serious liability for my plans to put an upflow in my garage? I was thinking if I put the 1st barrel on the concrete, it would keep it colder, but I just measured the temp in my garage right now and its already 90F and a bit humid. Today's forecast is 102F! If the conditions are not a problem, I plan to do this:



If the conditions are not ideal and will lead to problems, I will plan to do this instead:


Thoughts and opinions are greatly appreciated.

Thanks,
Bob

If the temperature is above 50°F then the PHO and animal fats won't separate out. In your hot climate this probably isn't a problem. If you're making BD then the bag filter isn't necessary.

Hi John,

Thank you for your reply. So when you say that the PHO and animal fats wont separate out, does that mean that they will get pushed into the 2nd barrel? I'm sorry if that is a dumb question, but I'm still learning

If it matters, I should have stated that the type of oil I get is rice bran and soybean oil from a Japanese restaurant that cooks alot of tempura type fried foods (light flour) as well as tonkatsu (panko bread crumbs). So it is not necessary to filter out lower than your door screen + panty hose method? I have 200 and 100 micron bucket filters.

Hi Bob,

What software did you use to make those nice clear diagrams?

Correct, at warm temperatures they are dissolved in the clear oil.

not if you're making BD

I suspect that the oil you've got has little or no PHO and animal fats, depending on what they're cooking.

John,

Ok, I think I got it. Since my oil is pretty clean to start with, is not a partially hydrogenated oil, and is a plant based oil, I'm good to go. However, and here's the light bulb moment for me, if it was PHO and/or had animal fats as part of its ingredient, it would be absolutely necessary that the ideal conditions (65F) existed...right?

One thing that does concern me though is that they cook fried pork in there. Perhaps on occassion, fried beef. But making BD should take care of it, right?

This is all so cool. Thanks for being patient and helpful, John

That temperature or lower to settle out the PHO & Fats, but only if you were running an unheated VO-ULSD mix like I am.

If you have a heated VO fuel system, or are making BD, then it's not an issue.

Just let your cold weather BD settle in a poly barrel and pump your fuel from the top 3/4. That way any higher melt point fat/PHO BD settles out in the barrel not in the vehicle fuel system.

Glad to help...
