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.
Finding used freeze dryers isn't easy. That's because most people who get them consider them a long-term investment. As such, they hold on to them for years. However, a used freeze dryer or two sometimes makes its way onto the market.
Racquel Ruetz Albert was quick to respond to my inquiry about the delivery of our harvest right freeze dryer.
Theoretically, you could use the machine for both gluten and gluten-free foods. However, we choose to put only gluten-free items in our freeze dryer to avoid any potential cross contamination.
And once you have resolved your issue I hope you will stay around and talk to us all about what you have been drying in your machine, etc.
Adopting such technologies puts these businesses in a better position to meet regulatory standards and makes them more viable in the market.
The Celiac diagnosis was the real catalyst that made up my mind to purchase a freeze dryer. I can now freeze dry my son’s favorite homemade gluten-free foods as well as a few pre-made gluten-free foods that are safe.
We’ve bought six so far with two more on the way. But families and individuals considering getting their own can and should as long as they go in with their eyes open.

I remember reading somewhere in this thread where somebody was asking how long you run the freeze get more info 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 total 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.
Pre-frozen food takes less time to process since the machine doesn’t have to completely freeze the food. Your climate (humidity and temperature) can also affect the cycle length. My average load takes around 24 hours, but it can be significantly longer.
Not all of us are technical experts (the 'not' category includes me) but I hope someone who can help you will come along soon.
5 Posted September 16, 2015 Thanks dsheidt. I was afraid that the AN8 fittings I could find might not be long enough to provide the space needed so that the oil could flow over the top of the filter, especially given my "disk" method of holding up the can.
As I mentioned before, freeze dryers are an investment. They're an investment because of all the benefits they bring to you and your self-reliance.
Considering that they don’t blow heated air away from a hole in get more info your property, warmth-pump dryers use about half the Electricity of the vented dryer per cycle.
