Its a simple exercise so i thought i'd show. Probably not so much advice for the experienced but more for those who have pondered buying a dehydrator and getting away from packaged food. Here is enough for perhaps 10/15 Big meals.:
* Buy mince from a butcher, what drying mince shows straight up is just how much water the supermarkets can get meat to soak up!
* In the pan is 2.5kg of mince (a generous sprinkle of garlic (powder-nice and strong), about 100g's of (no salt) tomato paste and an a good doloping of bush tomato sauce are added late in the cooking).
* No oil, turn it regularly and chop it with that plastic LMF strainer or something similar.. (makes the job Much quicker)
* Usually do 2 lots (5kg) like this, it will fill 5 trays of a standard ezi-dry dehydrator. Broken up well before drying it takes 7/8hrs, generally let it cool t room temp before giving it another blast for an hour or so. I don't bother to rinse mince, it drys and re-hydrates well enough so long as it is of good (ie low fat) quality to start. This is just standard beef mince but game meats work even better, i did a batch of wallaby for myself and it was awesome (though it does seem to have a smellier exit

So its pretty versatile stuff, spag bol, shepherds pie, meat patties, m/bread burritos so on... all solid traditional fare high protein, low weight, hardly any fat left. I'm not sure on the life, We put it in 1kg fruit tubs and in the freezer, make enough for a few months. Rehydrated it comes back very much like a fresh meal, haven't yet had a freeze dry mince that comes close! (and tried many)...
