Not only does it spread the cost, but it can also increase the amount and variety of the preserved food you store away. Additionally, a group purchase can also lead to purchasing bulk quantities of food to freeze dry.
Electric Programmable Pressure Cookers, such as the "Instant Pot, are being used for small batch pressure canning. This fact sheet explains research showing why this is a food safety hazard, with a high risk of producing home canned foods that could devel
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.
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.
Removing the ice from between the chamber wall and the insulation (hopefully will never have to do this again)
To protect packaged foods and organic compounds against spoiling, mold growth, color change, and loss of nutrition, use oxygen absorbers to get the residual oxygen inside the packaging to below 0.
Granted, most of that time is the freeze dryer doing all the work, but the process is not without effort. Once the food is ready it must be put into appropriate containers with oxygen absorbers and sealed properly so they can last.
Hey there, fellow self-reliant folks! If you're all about preparedness and want to take your food preservation game to the next level, you've probably considered getting yourself a freeze dryer. But let's be honest – freeze dryers aren't exactly known for being wallet-friendly.

I remember reading somewhere in this thread where somebody was asking how long you run the freeze cycle with pre-frozen food. I have my chest freezer set to -12F, and I usually let the freeze dryer cool for an hour before I put the frozen food in. After I load the food in I wait another half hour to start the drying process. I've had a lot of cycles that the Completa time between pulling one batch out and starting the drying cycle on the next is around 2 hours. I'm running mine in a cold garage, so it cools down pretty quickly. If you have yours in a warm room it would probably take a little longer.
I thought an easier way to see what was happening would be to make a time lapse video of an entire freeze drying cycle. As I was about to prepare some apples for freeze drying yesterday, I thought it would be a good time to do that -- so out came the GoPro.

I did wonder though, since this is gravity flow and not pressure driven as on a car, if having the filter mounted horizontally might result in using only "half" the filter, as the oil would tend to travel through the low side of the filter -- although in practice, I suppose, as the filter material gets plugged it would force the fluid level higher.
Before you know it, you’ll be storing food and experiencing the many joys that cooking has to offer.
