A Computer program in ‘Visual Basic’ language was developed for fenugreek to rapidly determine the drying time and drying rate for a particular temperature and moisture content to minimize the operational problems. The drying was carried out in a tray dryer (Kilburn make Laboratory tray dryer) with heated air at a temperature of 50, 60, 70 °C and its combination. | Drying characteristics of fenugreek and its computer simulation for automatic operation
