I've seen the $3k "freeze dryers" in the farm stores; they look complicated and I wonder about maintenance. They're vacuum devices, no? Means changing filters frequently I assume.
Room temperature dehydration might be easier and give results as good or better. Have you tried commercial freeze dried blueberries? Is there something special about the texture or flavor that you find superior enough to invest in achieving?
- bartonfink 3y agohttps://en.m.wikipedia.org/wiki/Freeze_drying https://en.m.wikipedia.org/wiki/Freeze_drying The first sentence of the second paragraph explains that freeze drying produces different results than drying through ambient heat. There's much more in the article to explain the process and its advantages. If you don't know why did you comment?
- h2odragon 3y agoi do cold dehydration with forced air, no heat; for various things. it's great for delicate flavors etc that can't take heat. it requires time. ive had freeze dried fruits and didn't care for the results, compared to regular "dehydrated". but others might prefer things that way; perhaps its especially good for blueberries. i think it makes apples into packing peanuts.
