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.
It's awesome! I don't have a freeze dryer yet but am planning to place an order tomorrow. I am super curious how Kerry's scroll pump is holding up... eliminating the oil from the equation would make this whole thing SO much easier.

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"?
This includes setting as many as five different shelf temperatures, thus allowing the material to dry in Shop Now 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.
Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
Based upon your work experience you probably know more about vacuum pumps than most of us. Chasing a vacuum leak can be frustratingly difficult.
And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.
