This will be my first time making jerky in my new Redhead Dehydrator (drawers not stacks)
What's the optimal temp/time for the jerky to cook at?
OK, no experience with bison or your exact dehydrator. But, I have a Presto 6301, digital adjustable time and temp. I've made both solid and ground beef jerky. Recommended temp in my instruction manual is 160F. They also recommend precooking the meat to be safe. I don't precook. I think it would destroy the whole point of beef jerky.Time will vary. Mines never less than 4 hours, nor more than 6. YMMV....
I do mine at the highest temp I believe it is 160° I have the cabelas 80liter shown in your link. It will hold 20 pound of meat most of the time I do 10 - 15 pound batches, takes around 8 hours to do.
I have a cousin that was looking for one he bought the Nesco in your link and is happy with it, he doesn't make that much at a time.
The StX in the link looks interesting, and a decent price compared to the cabelas and the Xcalibur.
Figure out how large of a batch you are going to do at once, that is where I would start my search, with the tray sizes listed you would have an idea of how much they would hold.
