I would prefer those fittings to have internal Este rings and knurled thread on ports (similar to R134a vacuum gauge sets) that do not require high torque compression fittings. Finger tight and you are good to go. You spot a leak, change the O ring and you're back in business.I will place a piece of parchment over the baking sheet and add another layer of fruit. After it is frozen solid, the fruit can be taken off the tray and placed in freezer bags if needed.
What I should have done was just sent a freeze dried meal that would take me 3 minutes to rehydrate and he wouldn’t have to be stuck in the bathroom for days on end. Lesson learned!
After it’s processed, I weigh the tray again and subtract the ending weight from the beginning weight. That tells me how much water to add for reconstitution. I like to write on the mylar bag or jar lid how much water to add so I don’t have to guess when I am ready to reconstitute the food.
Nor is it affordable for all of our extended family to eat gluten-free for the holiday meals. This challenge has been easily remedied with my freeze dryer.
Freeze drying is a dehydration process that removes moisture from food while preserving its structure and nutritional value by freezing it first and then creating a vacuum around it.
Freeze drying isn’t my only preservation method, but it’s my favorite. Keep the skills of canning, dehydrating, fermenting and more in your pocket so you have various ways of preserving food. They all have their pros and cons but non-e should be ignored.

The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
If you don’t have the time or money, or if you believe the food crisis will hit hard very soon, then it makes more sense to buy freeze-dried food instead.
Making food in your own freeze dryer is less expensive than purchasing Buy Now it commercially. You can purchase food in bulk and freeze dry it for later. With the current high food prices (which could easily continue to skyrocket), it’s nice to buy in bulk or on clearance to save money.
