I do a lot of Jerky on my IQ4 FEC.
18-20 lb batches every few weeks are normal it seems.
To me, jerky is a two step process.
I like to cook (smoke for flavor and heat for food safety) it then dry it to finish the process.
I use "Eye of the Round" as a beef cut. It is the most cost effective in my area. Sliced 1/4 inch by 1 inch and marinaded a day or two. Home made Soy Sauce based marinade.
I dust with Emeril's Esesence on the racks for additional flavor.
I cook in the FEC on my 6 shelves for 3 hours at 170* with hickory, mesquite, or a blend of each for flavor. Love the Mesquite on beef if it is not overdone!
I found some of the real light weight expanded metal and cut to fit the shelves for Jerky and small stuff like veggies. Easy.
Then into my Excalibur dehydrator to finish the "jerky drying" part. Normally around 6 hours at 145* with a lot of airflow. The airflow is critical for good drying IMHO.
Lots of different ways to get there--this one works for me every time thanks to the FEC!
