Dryer Design Calculator
Calculate water removal, drying time, energy requirements, and exit humidity for batch and continuous dryer operations.
Inputs
kg/hr
mass fraction
mass fraction

m³/hr
(1=batch, 2=continuous)
Results
Water Removed
578.95 kg/hr
Dry Product Rate
421.05 kg/hr
Estimated Drying Time6.95 min
Energy Required1,538,321.05 kJ/hr
Air Exit Humidity0.1 kg/kg dry air
How to Use This Calculator
- Enter the Wet Feed Rate in kg/hr and the Initial Moisture Content as a mass fraction (e.g., 0.60 = 60% wet basis moisture).
- Enter the Final Moisture Content as a mass fraction target (e.g., 0.05 = 5% residual moisture).
- Enter the Drying Temperature in °C and the Air Flow Rate in m³/hr through the dryer.
- Select Dryer Type: 1 for batch (fixed charge, longer cycle) or 2 for continuous (steady-state throughput).
- Review Water Removed in kg/hr and Dry Product Rate in kg/hr to confirm throughput matches production requirements.
- Check Energy Required in kJ/hr and Air Exit Humidity in kg/kg dry air for utility sizing and exhaust treatment design.
