Re: [Biofuel] Problems, problems, problems
No, I did not titrate, but made 9 batches of 20 ml in a tube, starting at 3½ gram / ltr of oil, next 4 grams per liter, 4½ grams/ltr etc. In this way I have made a lot of BD now and it works fine. There was no difference at all, they all turned hard and the color was like coffee with milk. The E900 so they call it, is added at a mixture of soja and palm oil or a mixture of rapeseedoil and palm oil, at a rate of 3 ppm. There is nothing else in it, so the manufacturer assured me. When I try good oil from other restaurants, everything is fine, but as soon as there is any oil from this man in it, I have the problems there. Of course a solution would be to stop collecting oil from there, but many restaurants use the same oil and they have the same scedule of renewing the oil. They sell high quality chips and snacks and the last thing I expect is, that they would use their oil too long. So, I have no idea what is happening. Could it be something like polymeres ? I don't know anything about polymeres, so maybe it's a stupid question. Thanks all in advance. Pieter. Pieter, I agree with Kieth, it probably is not the anti-foaming agent which is there in parts per million conc(?). Have you titrated the stuff? Maybe a very high free fatty acid content? Or maybe it is all saturated fat? Another possibility is that something is extracted into the cooking oil in significant quantities, which solidifies when it is diluted with more oil?

Re: [Biofuel] Problems, problems, problems
Dear Keith, I have followed your forum for a while. You said that "It's used here in Japan too", is that mean you are currently in Japan? The reason I asked is that if yes I would like to visite you to see physically your projects.

Re: [Biofuel] Problems, problems, problems
Thanks Keith, If the silicone is not what is gelling the BD, what else can it be ? I still make BD from other suppliers without problems, but as soon as I mix any oil from this particular adress in it, it turns hard. With "hard" I mean as hard as butter in a fridge, so not jelly. Ok, but IF it is caused by the silicone, what can we do ? Because we will have to deal with this more and more in the future.

[Biofuel] Problems, problems, problems
Hello all, I found a new adres where I can collect quit a bit of good quality oil, well, that is what I thought. In this oil is added what we call E900 ( a european code ) which is dimethylpolysiloxaan, to avoid the oil from foaming when they bake their chips. From this oil I get one great big lump of solid stuff when I try to make BD from it. Can anyone please help me ? Of course I could go and look for another restaurant, but this E900 is used more and more, so I will meet this problem more often in the future. E900 is a polymere from silicone : (C2H6OSi)n Met dank en vriendelijke groet,Pieter KooleNetherlands ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
