01%, effectively preserve these packaged foods without the need for preservatives or additives and without the need for vacuum sealing.

Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"?

I think a community-built troubleshooting manual is a great idea. These machines are simple in some ways, and more complex in others, and having a lot of eyes on the problem is always good.

Unlike laboratory freeze dryers, they usually don’t need drying at such high speeds, which is the biggest difference between the two.

I, too, have noticed a significant difference when I defrost mid-cycle. I do that routinely now. I carefully use a heat gun to "shock" the surface of the ice, moving back and forth across it fairly swiftly, which causes it to crack and separate somewhat from the cylinder.
