Non-fat dried milk (NFDM) is suitable for short and long term emergency food storage. It is made from non-fat, grade A, milk that has been dried by spraying into hot air or heated on a drum. The process removes nearly all of the water prohibiting the grow
The only downside is that the interior is now so cold that defrost time has doubled! I use a large high volume fan to defrost the unit, not the heat trays. It used to be a 15 minute job, now it is closer to 30 minutes.
Ideal vacuum pressure and drying temperature is maintained for each material and preserves freshness and potency
Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
There are three things that cause organic material to lose its freshness and begin to degrade – Water, Heat, and Oxygen. Harvest Right has a solution to these problems.
They replied with some good information, but didn't really directly answer the question. I know that there is pelo one answer for all foods, but a rule of thumb is certainly within reason.
Remove all ice every oito hours of drying time. It is amazing how much faster the drying time drops doing this. A side benefit is water vapor does not contaminate the oil as fast. I've gotten up to 20 cycle per oil change by carefully monitoring the oil and water.
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.

We have to face one hard fact when shopping for home freeze dryers. That fact is, unlike many other purchases, freeze dryers aren't cheap. However, unlike many other purchases, a freeze dryer can provide a lifetime of cost savings that ultimately pay for itself.
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.
Freeze drying lets you say goodbye to food waste by extending the shelf life of your food. Every dollar you save on groceries goes back into your pocket.
