Oh, I just learned that there is a specific "candy mode" in the manual set-up of the harvest right. But you have to be careful about spacing because of the expansion that occurs with very high sugar foods. I've never done candy, myself.
My favorites so far:
eggs - blended and freeze dried raw...
It depends on the candy. Some will foam up. And, because the freeze-drying process includes some heat in the vacuum cycle - you can't do chocolate. It melts. You can do chocolate flavored things, like cakes, etc. I've done cubed-up ice cream bars as snacks, and they worked. Very yummy
It's a bit of an up-front investment, for sure. Boy, I tell ya, though ~ I have lots of eggs in storage. And you'll stop wasting leftovers.
There are certain foods that are best not freeze dried. Fatty, oily, very high-sugar foods are not recommended. This is where those freeze-drying...
For those foods, expect about 24 - 30 hours. Room temperatures can affect the length of drying times. The machine does not indicate when the food is done. You check it after its cycle, and determine if more time is needed
I have a Harvest Right. I went with the medium with the premium oil pump. It's a bit loud, but I'm used to it. It puts off some heat. Runs best in a cool area. A dry basement would be ideal. Unfortunately, I don't have a basement, so... kitchen it is! If you do get one (or want to learn more...
I don't have large gardens, like many of you do. We're in the burbs. Which kind of makes freeze drying ideal. Not many of my veggies produce enough at any given time to warrant canning (yet - I'm working on that), but you can always fill a freeze dryer tray! My freeze dryer has 4 trays, so I can...
