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.
Be aware that it is very important to drink liquids when eating freeze dried foods that haven’t been reconstituted.
Our electricity was very high when we had it in AK because our electric company charged a lot, but in Texas, it’s very cheap to run. I don’t mind that I can’t freeze dry some things, as most of the things that you can’t freeze dry, you can purchase commercially or they shelf stable as is. For instance, I don’t freeze dry butter, but I do buy powdered butter. Oh, here’s one more potential con:
Truth be told, there isn’t much of a difference in terms of interface, but the Pharmaceutical models do offer a bit more customization in terms of settings. The Home Pro models however get the job done just as well and have bigger capacity for the money.
Raymond Shipka My freeze drier arrived perfectly and professionallly packaged and it works like a charm.
If you or a family member has Celiac Disease, you know it’s not easy to come up with a last-minute meal. My freeze dryer has made this so much easier!
Freeze dried foods are delicious by themselves or powdered and used in smoothies or baked goods. I have found I can freeze dry apple slices, powder them, and add a little water to make applesauce. It’s a lot easier than making applesauce in a traditional way.
After buying our freeze dryer I was naturally curious as to how it "knew" when something was done, since batch times varied so much depending on what was being processed. Watching the cycle times didn't seem to tell me anything at first website -- especially without a thermometer to tell me what was happening inside -- until I finally caught on that applying heat to the frozen food affected the vacuum, which provided the measure of how dry the food had become.
This Know More 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.
The best way to keep tabs on used options that may be available is by joining freeze-drying Facebook Groups, following them on Instagram and TikTok, or checking online self-reliance and preparedness forums.
- Complete Meals: Casseroles and soups can also be freeze-dried for convenient meal prep options later on.
4. Noise Level: Some models can be noisy due to their vacuum pumps; consider where you will place the unit.
Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
•Control of the shelf temperature during the dry cycle. This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures.
