How to Size & Budget a Commercial Food Dehydrator System

Convert target finished dry kg into wet batch load, tray count, water-evaporation kW load, equipment pricing, and factory acceptance checks.

Always Size Dryers by Kilograms of Water Evaporated—Not Finished Weight

The #1 sizing mistake new snack and jerky plants make is asking for a ‘100 kg dehydrator’ when they need 100 kg of finished dried apple chips—which actually requires loading 650 kg of wet sliced apples and evaporating 550 kg of water! Built on dehydration airflow and process specs, use our calculators and guides to size thermal capacity right the first time.

Run your numbers in the wet-to-dry yield and tray calculator and crop temperature & airflow chart, then consult commercial food dehydrator price, how to choose a commercial food dehydrator, and our dehydrator sanitation & FAT checklist.

Wet batch and hourly capacity comparison across kitchen cabinets, RXH truck ovens, vacuum dryers, and mesh-belt tunnels
Transition from batch trolley cabinets to multi-layer mesh-belt tunnels once continuous wet feed exceeds 200–300 kg/hour.

Quick Sizing Conversion Steps

Four equations every processor should check before choosing cabinet vs belt:

Calculation Step Formula Worked Example (50 kg Dry Jerky / Batch)
1. Wet Raw Input (kg) Finished Dry kg × Wet-to-Dry Ratio 50 kg × 4.0 = 200 kg sliced marinated beef
2. Water to Evaporate (kg) Wet Input kg − Finished Dry kg 200 kg − 50 kg = 150 kg H2O removed
3. Tray Count Needed Wet Input kg ÷ (2.5 to 3.0 kg/tray) 200 ÷ 2.5 = 80 trays -> 2-Truck RXH-II (96 trays)
4. Heat-Pump vs Electric kWh Water kg × (0.45 HP vs 1.25 Elec) ~68 kWh (heat pump) vs ~188 kWh (resistance)

Commercial Dehydration Engineering Notes

  • Single-Layer Loading Rule: Overlapping meat strips or fruit slices doubles cycle hours and creates dangerous wet pockets—size tray surface area for a single unstacked layer.
  • Check Exhaust Duct Routing: Open-loop electric/steam ovens vent 150+ kg of warm humid vapor per batch; route insulated stainless exhaust ducts directly outdoors.
  • Verify 3-Phase Amperage: If your facility lacks 30–45 kW spare 3-phase capacity, closed-loop heat-pump dehydrators cut connected electrical load by more than half.
