Overview
NESCO designs the FD-37 as a stackable round dehydrator whose fan pushes heated air down the center chamber and across each tray, so no tray rotation is needed. A clear top cover lets you watch the drying.
Even airflow without tray rotation and room to add trays suit jerky makers who want to scale up. The limits are the single temperature and hand-only cleaning.
Who it's for
Beginners and regular jerky makers who value consistent results without shuffling trays suit this machine. People drying many foods that need different temperatures need a dehydrator with a dial.
Pros and cons
- No tray rotation needed
- Expands with extra trays
- Clear top cover
- Seasoning and cure samples
- Fixed temperature only
- Not dishwasher safe
- Extra trays sold separately
Performance notes
A fan sends heated air down the center chamber and then across each tray, which gives consistent drying without moving trays around. A single fixed temperature removes the guesswork for jerky, but not every food dries well at one setting.
