HMPEs or monoglycerides?

One of my collections last week had what looked like parafin wax settled on the bottom of his unused KTC Soya.
There was about 0.5L in each of his cubbies. Could it be this that appears in the Bio?.

hmm not sure! A clear 10/90 should show a near 100% reaction.  There's something happening post reaction.  I've had the stuff from very clear / runny feedstock as have others.

Sooner or later, somebody with some decent lab test kit will put us all out of our misery!

Firstly welcome to the forum

Does he keep the oil somewhere cold?

All oils contain triglycerides with all manner of melt points, some of them do indeed wax before others.  Turning such a thing into biodiesel normally elevates the melt points such that at the same temp, this waxing is not seen.  I was of the impression that biodiesel conversion raised the waxing temp by 5-10C or so.

I wonder if the likes of Chemiphase or Trinity could look at their winterising formula to solve this problem?

The oil is kept in a warm room. I brought some home to test. It is hard, white, gritty and melts into a clear liquid. Could this be the antioxidants used in ktc.

Just got an inverted 750cc rotor fuge for feedstock.  I'm going to experiment and see if there are improvements with very clean oil vs. just strained and glyc washed. 

Off to see JRL for a tank to do this next week, should have the new processor in a week or so too, so I'll any findings.

If the establishment uses frozen chips what you could be seeing is palm oil residue.
