Not all, but most samples I test that have been venturi dried are high in water (5 to 800ppm) I think the answer would be to pull the incoming air through silica gel.

Mine came out at 300ppm water when dgs tested it yesterday which i was very pleased with

Yours was one of the few exceptions to the rule, Jules. You will have to tell others who dry this way your secret.

Warm clean Cornish air. Maybe the salt in the air drops the moisture level?

That's an interesting thought ... any one tried adding salt to bio to dry it?

I don't know about the salt but if Jules r/h is low it will certainly help.

I use a lot of salt for my emulsions , I thought I would be better after 9 years

At least it's better than using acid.

If you are getting emulsions from a slight underreaction it is due to monoglycerides. if the emulsion is from an overreaction then it is due to soap.

You have to get your bio into the 'Goldilocks' zone at the end of your reaction. Then after de-mething or 5% prewash there will be no emulsion when you water wash.
