I am looking for a more defined "heuristic" curve based upon the internal temperature. I am sure that your engineers probably have tables for such things. I also know that different foods freeze at different rates, that is why I am asking for a heuristic answer.
The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle.

If you store something with fats and oils in it, it can go rancid quicker than those without it. So again, something that has a higher fat content, it may only last about 10 years instead of 25 years.
•The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the unit has control of the attendant vacuum pressure.
Is it as cheap as buying at the store? No. But properly freeze-dried and stored meats can last ten years or more without refrigeration. The freeze-drying process can be challenging, but those who have the time and patience should consider doing it.
3) Inside the front panel I installed a plastic shield over the display card and a water deflector just below the hole to route the exterior condensation to an 11x17 pan beneath the FDer.
This is why so many people are buying their own freeze dryers to use at home. The market is essentially cornered by Harvest Right, which isn’t a bad thing since their quality and customer service are both superb.
Another emerging trend is the production of environmentally friendly and energy saving freeze dryers. Manufacturers are trying to lower the carbon footprint of their machines by introducing more energy efficient and sustainable devices.
Thirdly, I like to know what is in my food. When I process my own food, I know what is going in it. Also, I like to grow my own produce so when I freeze dry that, I know exactly where my food came from and how it was grown. Buy Now Some commercially freeze dried foods contain preservatives.
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.
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 food options we had there were extremely limited and full of preservatives. To counter that, my buddy Lance went in with family members on the purchase of a freeze dryer for home use.
