You seem like you know what you're talking about. I know pretty much nothing about freeze drying. 600$ to 1k$ actually seems reasonable enough for my personal production. Would I need anything else? My mental model of the process is...grind (I think it needs a different grind than pourover), put into the magic freezer machine, wait and have instant coffee to take to work :P
What's yield/power consumption etc. (for such a lower end consumer version). Anything else I should be aware of?
- freese 10y agoInstant coffee is liquid, brewed coffee that then gets dehydrated. 1) grind the coffee 2) brew it however you like 3) cool the coffee from 90C --> cold 4) freeze the coffee 5) freeze dry for 24-48 hours Fundamentally this will work but you're likely to run into a few problems. Your yield is going to be pretty low - one batch will likely get you ≈10-15 cups. Secondly, that coffee is really hygroscopic, meaning that it's so dry that it will absorb any moisture from the air. Unless you keep it in vacuum pouches it'll turn into a rock within days.
