Hot Pan Test Failure

My HPT did not pass. Here is what I did...heated oil up to 150*, turned off HWH within 15-20 minutes of when it reached 150*. I then let it cool down for 4 days. I opened the bottom valve and ran oil into a clear quart jug I could see water droplets the size of dimes and nickles in the bottom but no defined layer. I drew another quart and the same thing dime and nickle size droplets of water. I did this a third time and the droplets are now smaller...the size of a pencil. This seems like a waste of alot of good oil. I did it a 4th time could not see the droplets of water. I then pulled a cup of oil off the bottom for the HPT and it crackled poped like crazy. What did I do wrong?

First off, why did you turn it off right when it reached 150*? Mines takes a couple hours just to get to that heat and then I let it cook for the better part of the day. Better for seperation. 2nd, you may need a new oil source, I've never seen water droplets that size. Restaurants that don't cook a lot of frozen foods are better sources. I would be worried about that much water after 4 days even though I let mine settle 10-14 days. You can't even think about running that.

I am new at the SVO stuff and was not sure how long I should cook it. This was my first batch through my set up so there may have been water in the HWH to begin with. So what should I expect the crud to look like and how much should come out?

Dry oil is crystal clear. Any opacity indicates the presence of water. The only exception is filtered fats that have been de-watered. They will cloud up when they gel at cool temps.

You don't have to "cook" the oil. I think your 150*F mark is too low since your oil obviously is very wet. Heat to 180*F then stop the heat.

You say you wait for four days. Is the exterior of your HWH insulated? I know HWHs are internally insulated, but extra insulation is very important because de-watering occurs during S-L-O-W cooling. Get a roll of R-13 and some duct tape.

I have a bottom drain for water, sediment and fats.
I have a standpipe drain for the dry oil six inches off the bottom.
I pass the HPT 90% on my first try and always if I heat again.

Can you explain the standpipe drain?

Here is a pic of my HWH and Filteration system. As you can see I only have one drain.

from HERE

I used the plans for a bioD wash tank for my de-water drum.

You can also do a stand pipe from the top. Since you have a HWH you can have a piece of pipe come in from the top, but have it draw 6-8" from the bottom. That way you wont have to take apart your HWH to get a fitting in there. try 150-170 for about 6-12 hours then let sit for a few days.

I now have the temp up to 160* for 4 hours...then let it cool down for 2-3 days. My first batch after doing this passed (no crackling). I am on my second batch and I am getting some crackling. What amount of crackling is acceptable if any?

I did a search of HPT on this site and did not get any hits. Thanks for your help.

Acceptable crackling
For me any bubbles are not acceptable.

i heat to 140*, turn it off when it gets to that temp and let it settle overnight and its always dry oil. I don't think there is much water in the oil i get. Also, filter your oil BEFORE you HPT it. This is the final stage of filtering/dewatering and filtering removes the particulats that are holding suspended water...remove the particles and you remove the water.
