Thanks for sharing.

I looked into freeze drying years ago and learned the Aztecs used to do

it by merely taking their goods up into the mountains, where it was

freezing and the air pressure was lower than where the food was grown,

so I assume you don't have to get it down very low to start seeing

results.



From that, I wonder if a common automotive vacuum gauge have any value in monitoring the level of vacuum?

Meanwhile, at a different ranch, I use polypropylene bags for my copper plating processes. The plating material has to roll off the copper or other anode in the bag, then through it and on to the item being plated in a plating solution.

From that, my next "I wonder" is, would a polypropylene bag would make a handy container for holding the desiccant, to reduce the likelihood of contact with the food?

SIDE NOTE: As a kid, I worked a truck stop in a small farming town. We repaired a lot of tractor tires. They were filled with calcium chloride and I learned, very quickly, it would shrink a brand new pair of boots very quickly. So, even if it's in a water solution, once that water evaporates, it'll be more than happy to reach out and grab some more - from your soon to be ruined new boots.



There you go, another ible explaining how to "grease" your new boots (replace lost moisture with oil or melted grease). Fun times?
