Drying characteristics of banana: theoretical modelling and experimental validation

The post-harvest losses of agricultural products can be reduced drastically by using proper drying techniques. In the present study, a mathematical model for drying of food products undergoing shrinkage has been developed. The model, which includes the influence of both material and equipment, is...

In the present study, a mathematical model for drying of food products undergoing shrinkage has been developed. The model, which includes the influence of both material and equipment, is capable of predicting dynamic behaviour of the dryer. Heat and mass transfer equations are solved simultaneously using a numerical technique. The material model is capable of predicting the instantaneous temperature and moisture distribution inside the material. The equipment model, on the other hand, describes the transfer process in the tunnel dryer and predicts the instantaneous temperature and humidity ratio of air at any location of the tunnel.
