I have a nesco food dehydrator that does well for us. It sits on the kitchen table so there are no waspsI par boiled some French beans for the freezer and I've tried sun drying tomatoes in the past. You need a decent fruit dryer ( a cased in unit with a glass roof here) or the wasps, flies and anything else that fancies a snack gets them. You could of course go the Sicilian route and let grandma sit outside with a fly swat turning the tomatoes on a rack.
We would need at least 2 large freezers, a medium sized room with good ventilation for the potatoes, beans, onions, garlic, chilli and mushrooms.
Then there's the figs and the nuts......
We produced a lot of stuff one year and what was needed was a proper canning process. It's not going to happen here.
