Hey all, so I have an idea. I want to make a freeze drier. I think I have the physical components, an ice maker and a vacuum pump. I'd like to document and discuss the project here.
Awesome shok! Keep us up to date!!
How does one build a freeze dryer?
It needs to basically cool things off a lot (ice maker), then pull a vacuum on it so that the ice sublimates (straight from solid to vapor). I'll have to do a little research, but I do have a vacuum pump, and I have an old unused ice maker, the platic piece that pushes the ice off cracked, but the getty-cold-maker part seems to be fine. So first step would be that going into an airtight box with shelves to put fruits on and then figuring out the control programming.
Progress update?
