Thanks Ian
You right I skipped the washing in
the 1 liter batches and I
thought its the easy part any way I read a lot about washing and emulsion since
then. After all the reading I came to believe that if you have a soap or soapish
lair in between BD& water you got a problem in the process found mine
already it was the temp. In the processor couldn’t keep it
steady.
Already had a successful 80 liter batch
yesterday (the smallest I can in this processor)
Thanks again & happy New
Year

Hi Golan
2 things, 1st read all the JtF site as there are some
contradictions such as BD should be clear after processing then in the washing
section it says the BD maybe cloudy and need to dry/settle for a couple of
days in a sunny place. There is also a good section on
emulsions.
2nd do small 1L test batches to sort these sort of problems
out before going big. this includes not only changing the chemical ratios but
drying the oil and checking the accuracy of you measuring
equipment.
I have done quite a few test batches before going to 15 then
30 L batches.
Have fun
Ian

Hay
Just joined the biodiesel world and this group as
well.
I’m from Israel & my name is Golan.
Just mixed my first 100-liter batch.
I use
electric pump about 16 liter a minute
&
2.5 kw
heater.
I preformed quality test (150 cc water &150 cc
biodiesel shaked toghether in ahalf aliter jar) after 24 hours
and got 4-5 millimeter
white layer
In-between the biodiesel and the water.
As well the biodiesel wasn’t clear.
I reheated the tank again to 52 deg C
And mixed it with 10% methanol and 3.5 gram of lye
per liter of oil.
Mixed it for an hour.
Any way I took samples after 20 and 40
min.
I saw the biodiesel was darker then in the first mix
and an extra very thin layer nylon like appeared on top of the biodiesel
.
24 hours later preformed another quality test no
spreration at all for aday and ahalf all ready it stays awaitish fluid.
does any one knows what that layer is and what is
there to do.
All the best
Golan
