Setup and Assembly
- Unpack all components and remove any packaging materials.
- Wash all trays, the fine mesh sheet, and the fruit roll tray in warm soapy water, then rinse and dry thoroughly. The motor base should only be wiped with a damp cloth.
- Place the motor base on a clean, dry, and stable surface.
- Stack the desired number of drying trays onto the motor base. Ensure they are properly aligned.
- Place the top cover securely on the uppermost tray.
Operating Instructions
1. Food Preparation
- Wash and prepare your food items (fruits, vegetables, meat, herbs).
- Slice food into uniform thickness for even drying. Thinner slices dry faster.
- For fruit leathers, blend fruit into a smooth puree and spread evenly on the fruit roll tray.
- For herbs or very small items, use the fine mesh sheet to prevent them from falling through the trays.

2. Loading Trays
- Arrange food in a single layer on the drying trays, ensuring there is space for air circulation. Do not overlap items.
- The trays can be rotated 180 degrees to adjust the height between them, accommodating thicker items.

Figure 3: Trays can be rotated to provide two different interlayer heights (1.7cm and 3cm) for various food sizes.
3. Setting Time and Temperature
- Plug the dehydrator into a standard electrical outlet.
- Use the digital control panel to set the desired temperature (95-158°F / 35-70°C) and timer (1-72 hours).
- Refer to a dehydrating guide for recommended temperatures and times for specific foods.

Figure 4: The intelligent control panel allows precise adjustment of drying time and temperature.
4. Monitoring and Rotation
- Periodically check the food's dryness. Drying times can vary based on food type, thickness, and humidity.
- For optimal results, rotate the trays periodically (e.g., move bottom trays to the top) to ensure even drying.
