How It Works
This calculator uses USDA-recommended drying temperatures and time ranges from experienced homesteaders. The adjustments are based on food thickness and altitude:
Why Temperature Matters
Too low a temperature allows bacteria to grow before moisture is removed. Too high and the outside hardens (case hardening) while the inside stays moist. The USDA recommends these minimum temperatures:
- Fruits & vegetables: 125–135°F (enzymes deactivate at 140°F)
- Meat jerky: 155–165°F (must reach internal 160°F for safety)
- Herbs: 95–105°F (preserves essential oils and color)
Benefits of Dehydrating
Shelf Life
Properly dried foods store 6–12 months at room temperature, up to 2 years if vacuum sealed and frozen.
Nutrition Retention
Dehydrating preserves 80–90% of nutrients versus canning (40–60%). Vitamin A and fiber remain intact.
Weight Reduction
Dried food weighs 10–15% of fresh weight — perfect for backpacking, emergency kits, and barn storage.
