I have had my gl type processor for nearly 3 years now. I had a water misting head fitted in the top of it which I use for water washing. I only water wash in winter.
After using it for about 18 months, last winter the misting head blocked so I removed the 2 1/4 threaded plug in the top of processor. When I looked inside I found the eductor and the pipes inside all had a growth of some sort all over them. It was like brown oily "leaves" hanging down.
I cleaned it all out and continued to use the processor about once a month.
Last week I did a batch and tried to water wash for the first time this winter. The spray head was blocked again. I looked inside and, you guessed it, full of home grown veggie leaves again!
Anyone got any ideas what this stuff is?

I had trouble like this it was the paint peeling off from inside the processor.

Ah, I hadn't thought of that. Could be. But seems odd that after I cleaned it all out the first time there was no paint left inside. The first picture, looking down into the processor was taken just before I cleaned it and it shows no paint on the sides or bottom.
But now, a year later there is loads of it again. Maybe there is paint hanging from the top that I missed when cleaning but it is all over the pipes and eductor again and I know I cleaned them.
I have kept some of the "leaves". Don't look like paint. Wonder if there is a way of analyzing them??

Job to tell, but I reckon I've seen the same kind of stuff growing out of a water drinking trough in fields, when there is a slight leak on the ball valve. Just some kind of fungus that likes to grow in slow moving water.
Something will always try growing if it's damp and warm.

That's grim. Like greasemonkey I've seen similar in slow moving water (namely the condenser water drum) but that's a soft algae rather than what looks like the hard sheets you've got.

Try a bit fried with garlic butter............

Its very soft and floppy. Breaks easy. Reminds me of seaweed.

Does sound like what I've had. I killed mine with chlorine (though this probably isn't good for the copper innards of my condenser).

It certainly sounds like some sort of growth, but I'd have thought the sorts of temperatures at which we de-water and process and the harsh chemicals we use would have killed any organisms.
Do you leave the processor full of oil or bio at any time?
-
I sometimes leave the processor full of oil for up to 3 days before I process and then pump out.
I have a distant memory of someone either on this forum or vod having a problem with similar stuff in a fuel tank a while back.
