Hi YouTube my name's Geoff and I run a website called
vegoilcar.co.uk
I take ordinary waste vegetable oil, I clean it and run my car on it.
I had a question sent through the other day.
They asked if I had used strainers to clean waste vegetable.
Yes I have come across them so I thought
do a quick video to cover the subject.
Have I come across them? Yes. Have I used them? Yes.
Do I think they work? Unfortunately, no...
This be quite controversial
particularly amongst the people that actually sell them on eBay
by possibly Amazon etc.
But I just don't find that they work.
I'm talking about the flat-bottomed variety of sieve / strainer.
The sort you can see in this picture.
You can get them that filter into buckets.
This particular variety can stack one on top of the other.
And that was the idea I bought into.
It sounded a brilliant idea...
Stack say a course, then a medium, then a fine filter...
so let's say 1000 microns, 500 microns
200 microns and 100 microns.
So your pour waste vegetable oil in at the top
into the course medium
through the fine medium and out through the bottom.
Isn't that a wonderful idea?
Pity it doesn't work.
If it's worked for you, your oil is clean and warm. Mine isn't.
Mine's room temperature as I don't believe in heating oil because that liquefies the fats.
so working at room temperatures, no
it didn't work for me.
The receive I believe seems obvious and that's
because we're dealing with a flat bottom filter.
Why is this obvious to me and not the manufacturers?
I don't know... but to me what happens is
you pour the waste vegetable oil in and it's all mixed up
It has all manner of particulates
and fats contained in it and as you pour
it coats itself evenly across surface
of the filter. This forms a nice thin layer.
The oil seeps through quite quickly.
But as more is added
it leaves behind big deposits - which it should
because it's a filter! But as it leaves these fatty deposits
behind, they start to clog. And because it's a flat bottom,
they start to clog evenly. So very quickly
the entire surface is covered
with a thick gunge.
So the oil stops draining through.
Now It tried it.
I'd take 2 hours or so
just to try and pour through 20 litres.
They clogged. It wouldn't pass!
I'd pour it. It would stop going through.
I'd leave it an hour, but there'd be no change.
So I'd use a metal scraper and run it across the surface of the sieve
And I'd remove a load of fatty gunge.
Start again. Pour. Seep. Clog. Scrap. And so on.
So I quickly realised
it was because they had a flat bottom.
It coats EVENLY. There's nothing you can do with it.
So in my opinion a flat bottom sieve
just doesn't work! So should you but one?
Well yes and no.
... I've...
been known to buy them
but I don't use them as intended.
But that's because I'm a bit daft ; )
I don't buy them specifically
but because I had them I cut them up
and turned them into cones.
As a cone they work really, REALLY well!
Consider the same filter as a cone
rather than a flat bottom sieve
then obviously what's gonna happen is you pour the oil in
everything's going to be trying to work its way to the very bottom
of the cone, particularly the heavy
denser materials, the fats and particulates
they will try to sink to the bottom.
That's how settling works!
So the big stuff clogs the bottom.
And that's fine.
But higher up the cone
the oil is escaping through the filter.
So as a cone, it works!
I thing some entrepreneurial sort will probably make money out of this.
Good luck to them.
As a cone, it really works...
To any manufacturers I'd suggest
placing the whole thing
inside a funnel
and keep the sides of the sieve from
away from the sides of the funnel.
That way the two pass independently.
There you go, the perfect filter ; )
If you see them on the shelves you know who was the inspiration ; )
Please send me a royalty LOL
So in summary a flat bottom filter
doesn't work. Don't buy them.
If you have already got one, cut it up and make a cone.
Cones... that's the answer.
Thanks for watching.
fantastic filtering was special and I think that's it
no spiritual to the points if you got the questions on the swords
