Four tons of sorghum (final weight) is dried from 18% (db) moisture content to 13% (db) moisture content per hour. Calculate the heat requirement for drying and the necessary air flow rate for the drying system. Given that Dryer efficiency = 50% Latent heat of evaporation = 574 kcal/kg Specific heat of air = 0.24 kcal/kg °C Drying air temperature = 44 °C Ambient air condition = 25°C and 20 °C dry and wet bulb temperature respectively.

Question
Four tons of sorghum (final weight) is dried from 18% (db) moisture content to 13% (db) moisture content per hour. Calculate the heat requirement for drying and the necessary air flow rate for the drying system. Given that
Dryer efficiency = 50%
Latent heat of evaporation = 574 kcal/kg
Specific heat of air = 0.24 kcal/kg °C
Drying air temperature = 44 °C
Ambient air condition = 25°C and 20 °C dry and wet bulb temperature respectively.
