We dehydrate lots of things - most often potatoes, tomatoes, mushrooms, onion, celery, fruits - and A LOT of jerky.
We make jerkys from beef, deer, elk, turkey and chicken. We use a salty homemade marinade and dry the meats from the "raw" stage in a typical dehydrator (not an expensive model, but it does have a fan).
By far our favorite is to make it from ground meat. You get a soft texture, without using any chemicals like the commercial jerkys. Of course, we have a meat grinder, so we can grind all meats that we want.
To "shape" the jerky strips, we use a jerky gun. ETA: It works basically like a caulking gun. You fill it with the ground marinated meat, then push it out into strips directly on the dehydrator trays.:
The flat shaped tip in the photo makes the strips, two at a time. The round tip is for stuffing sausage casings.
