What actually matters
Ignore the tray count on the box. For jerky, four things decide whether you get a matched batch or a tray of shoe-leather.
Airflow that reaches every rack
Forced-air, horizontal-fan units dry the most evenly. Fanless boxes leave you rotating trays and guessing. If one thing costs a little more, make it the fan.
A thermostat that hits 160°F
This is the safety line, not a preference. The unit has to reach 160°F to clear the kill-step, and a digital readout beats a vague dial. If it tops out lower, you’re pre-heating in the oven every time.
Capacity you’ll actually use
Match it to your batches. A hunter processing venison wants stackable capacity; a weekend beef maker doesn’t need a tower taking over the counter.
Know your batch before you buy
Run the yield calculator to see how much finished jerky a pound of meat makes, then size the dehydrator to it.
