22F, achieved by dividing 9 hours by 110F (the difference in food temps). We both know that the FDer doesn't do linear as the temps fall faster early on and slowly peak to max low temps, but the food freeze time might be a tad more linear than the FDer as food is denser and must be frozen throughout.
Places like Craigslist are great for buying more or less anything, but there are more specialized online stores for used electronics, such as EquipNet.com; you can also find used freeze dryers on eBay and Amazon.
Be wary of buying freeze-dryers that come from locations where the unit could have been tampered with or damaged, even by accident.
That means that if you find any authorized online retailer that has a lower price than us, just let us know and we'll match their price!
Granted, most of that time is the freeze dryer doing all the work, but the process is not without effort. Once the food is ready it must be put into appropriate containers with oxygen absorbers and sealed properly so they can last.
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. 1
Easy preparation. Food is prepared for freeze-drying the same way food is prepared for regular freezing. After rinsing and removing blemishes, blanch most vegetables; pretreat fruits if necessary to prevent browning; meats can be freeze-dried cooked or raw; casseroles are typically assembled from already cooked foods.
Hey there, fellow self-reliant folks! If you're all about preparedness and want to take your food preservation game to the next level, you've probably considered getting yourself a freeze dryer. But get more info let's be honest – freeze dryers aren't exactly known for being wallet-friendly.
The differing vacuum levels during the system tests would be consistent with either a door seal leak or an drain valve leak.
Freezing a given number of meals means that you’ll only need to pop them in the microwave to defrost, once you’re ready to eat them. On top of that, they won’t go bad for months on end.

Dehydrators take the water off the surface first, then water eqilibrates with the surface, more water is drawn off the surface. You are left with a shrunken item, with some residual water. Makes gorgeous leather.
I love that the small freeze dryer can be placed on a kitchen counter. Having it in the kitchen makes it convenient and always ready to start the freeze-drying process.
Forgive me for the extremely long post but I thought other southerners may also face this problem and could use this information.
