3. Loading Trays
Arrange the prepared food in a single layer on the stainless steel trays. Do not overlap food items, as this can hinder air circulation and lead to uneven drying. For smaller or stickier items, use the provided silicone mats. Slide the loaded trays into the dehydrator slots.
4. Setting Temperature and Time
- Plug the dehydrator into a 120V 60Hz power outlet.
- Press the Power button to turn on the unit.
- Use the Temperature control buttons to set the desired drying temperature (e.g., 135°F for fruits, 160°F for jerky).
- Use the Timer control buttons to set the desired drying duration.
- The dehydrator will begin operating once settings are confirmed.
5. Dehydration Process and Safety Features
The integrated hot air circulation system ensures even drying across all 16 trays, eliminating the need to rotate trays during the process. The unit operates quietly. For safety, the dehydrator includes:
- Automatic Shutdown: One minute before the set timer expires, the unit will automatically switch to a cold air blowing mode to cool down the machine before shutting off completely.
- Overheat Protection: If the internal temperature exceeds safe limits, the overheat protection function will activate, automatically shutting down the unit to prevent damage.
