Spray Dry: What do you think of spray dry? Chat concludes:If the goal is civilization-scale dietary improvement Commodity citrus powder is the correct first move. (spray dry, not freeze dry)

Freeze Dry: Capex for open source freeze dry for 20 tons per day wet appears to be $4M open source based on $40M industry standard for freeze dry powder, with 6 month payback for open source capex but without PV. PV is around 1MW requirement ($200k capex for PV panels)
