How to Estimate Dehydration Time
Formula
Time = Base Hours x (Thickness / 5 mm) x (135 / Temp) x Humidity Factor
Thicker slices take proportionally longer. Higher temperatures speed drying. High humidity slows the process because the air can absorb less moisture.
Recommended Temperatures
Doneness Tests
Fruits should be pliable but not sticky. Vegetables should be brittle. Jerky should bend and crack but not snap.
Example Calculation
Apple slices 5 mm thick at 135°F with moderate humidity.
- 01Base time for fruit = 8 hours
- 02Thickness factor = 5/5 = 1
- 03Temperature factor = 135/135 = 1
- 04Humidity factor = 1
- 05Estimated = 8 x 1 x 1 x 1 = 8 hours
- 06Check at 6 hours, may take up to 10 hours.
