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 food and pharmaceutical industries crucially rely on freeze drying for the long-term storage of products. This method enables businesses to preserve product quality, extend shelf life, and improve stability.
I cut up a thin flexible cutting board to make the shields and secured them with clear high grade packing tape. The cutting board is stiff but it will fold and hold a 90 degree crease. The shields are not going anywhere, but are easy to remove if necessary.
What type of oil does the vacuum pump use? Harvest Right freeze dryers use food-grade vacuum pump oil, which is available for purchase. One gallon typically lasts several months with proper filtering and maintenance.
It freezes the product and lowers pressure to remove ice by sublimation. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the liquid phase.
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.
The differing vacuum levels during the system tests would be consistent with either a door seal leak or an drain valve leak.
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.

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.
The alternative was to simpIy cut a small section from the guard at the lowest point and allow the water to run down the front of the panel in a single stream. I am not crazy about the look, but it is absolutely necessary to protect my investment and the electronics. If you look carefully you can see the hole in the gutter beneath the center screw.

You can leave meat covered with boiling water in the fridge overnight. For salsa, reconstitute with cold water and let sit 5 minutes.
