There’s a potential opening for smaller businesses to get in on the freeze-dried market. Wonder how much the machinery costs?
Very expensive. In the $10K and on up range. Best to invest in a good pressure caner, a couple of hundred $ for a good one. Caned foods will not keep for 10+s of years like freezed dried and are good for up to a year or a little more. A good rotation and re-caning will do for most emergency food supply.
