HEAT AND MASS-TRANSFER RELATIONS FOR CROP DRYING

In present communication, an attempt has been made to study the heat a nd mass transfer for crops namely wheat and gram. The removal of moist ure from the crop was determined under simulated conditions and it was used to develop heat and mass transfer relation using linear as well as multiple regression analysis. The observations were recorded for re lative humidity, temperature of crop and air and for moisture evaporat ed. Experimental error in terms of per cent uncertainty was calculated for recorded data which is in the range of 20 - 30 per cent for force d convection and natural cooling, respectively.
