I finally finished the 220v wiring for my HarvestRight freeze dryer and got it set up again after moving.
I filled the five trays with various fruit items. Some bananas from our tree behind the house that we had previously cut up and frozen, some cut up papaya from our tree, some orange sorbet made from oranges off the trees behind our garage, and some frozen rasberrys to fill the last tray. These were then deep frozen in the unit for 10 hours. It gets cold!
I stopped the freeze a little early and let the vacuum pump start. When that happens the air is drawn out of the chamber and the temp makes an immediate plunge.
Then it goes into the drying cycle and the trays are heated to about 130°f and then allowed to cool again. These heating and cooling cycles continue with the vacuum applied which causes the moisture to sublimate and adhere/freeze to the inside of the drum.
This process removes nearly 100% of the moisture from whatever you have freeze dryed. Everything is super crispy dry and light as a feather!
This is the result: 2 quarts papaya, 4 pints bananas with a few rasberrys, and nearly 2 quarts of orange sorbet.
These jars are vacuum sealed and should be good for several years. For the longest storage life(approximately 20 years), put the freeze dryed product in mylar bags with oxygen absorbers.
