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.
Freeze drying with the Harvest Right Pharmaceutical Freeze Dryer completely removes all the water from organic material in about 24 hours. There is no other preservation method that can come close to eliminating the water from organic material this quickly.

Hrmm... maybe not freeze drying sorbet but I imagine using freeze dried fruits IN sorbet would give a much more intense flavour. Especially for things like watermelon which I've had great trouble sorbeting successfully.
On that point, I was first introduced to home freeze dryers while overseeing the guard force at the Embassy in Baghdad.
Installation of unit. This appliance cannot sit on the floor: both because it must be elevated for the ice melt tubing to drain into a container below it, and to be able to access the vacuum pump and the on/off switches for the unit.
I have one of those hand held heat guns (inexpensive from HF), but I was afraid of accidently burning the insulation. My gun gets very hot! I do the same technique with a fan, shock the ice and listen for the cracks as it separates from the chamber wall.
Using sublimation, the food retains much of its original texture, flavor, and nutrition when rehydrated. Freeze drying is broken down into two simple processes: freezing and vacuum drying. Foods are first frozen to well below 0°F. The colder the freeze the more efficient the next step will be. Once frozen, foods are subjected to vacuum drying. The air and water vapor (gas) are removed from the food processing chamber using a vacuum pump. This includes removing the water vapor that was once inside of the foods. When these two steps are properly completed, the food is dry enough to allow for safe storage at room temperature. Is freeze drying food safe?
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.
My husband has been contemplating cost effective alternative ways to get oil-less vacuum happening... what would the specs needed be, since I don't have a pump to look at. Hopefully I asked that in a way that makes sense.

19.7k Location:Ontario, Canada Posted January 25, 2016 So a couple of months ago (when the weather was still warm) Alleguede has his assistant drop off some raspberries that he wanted me to freeze dry for him. Since they were IQF raspberries I assumed that they would be individual - but apparently when you leave them in the trunk of Harvest Right Home Small Pro Freeze Dryer your car long enough to thaw, then put them back in the freezer - then take a couple of days to get them over to me - they are no longer going to resemble individual raspberries.
