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.
Let's do a simple math exercise. Non Frozen food put in freeze dryer at an ambient temp of 70F needs to be at -40F before the dry cycle begins. things go linear, each hour the temps would drop the food by 12.
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 routed the exhaust from the catch can to a home made catch can that consisted of a jar with two ports with steel wool inside. I wanted to see just how much oil would escape the newly install catch can and collect in the jar.
This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.
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.
Vic says: 2 years ago Going on a second year with the freeze dryer. Considering getting another one. It really takes commitment, but it is very rewarding. The freezer is good also, but it needs constant source of electricity, and the storage is limited to the size of the freezer.
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 -- 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.
Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
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.

Do you think it's okay to just purchase a reducer to go from the size of the exhaust to the size of the hose that came with the can? Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"? Thanks so much, Jen Hi Jen, Sorry to be gone so long. I did exactly as you proposed. I purchased a brass reducer and pushed the blue hose over it.
The current and emerging food crises in the United States have millions of Americans very concerned about the future. From supply chain shenanigans to food processing plants “inexplicably” being compromised to bird flu decimating the poultry industry, more info it’s pelo wonder there has been a sharp rise in the “prepper” food industry.
It definitely helps to have a freezer nearby. You’ll cut time tremendously by freezing the food first rather than having the freeze dryer do it. It’s also cheaper.
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.
