I think this method is closer to desiccation without heat than it is to real freeze drying. You can make beef jerky without heat by constantly circulating cool dry around around the meet, but it is not the same as freeze drying meat. The freezing and vacuum sublimation process is critical to the freeze drying outcome and can't be replicated by simple desiccation. That's why freeze dryers are expensive. It's much more than this method is able to accomplish.
