Drying is an essential process in the preservation of agricultural products. Various drying methods are employed to dry different agricultural products. Each method has its own advantages and limitations. Choosing the right drying system is thus important in the process of drying agricultural products. Care must be taken in choosing the drying system. Study comparing traditional drying and other drying methods for the reduction of the drying time and to a significant improvement of the product quality in terms of color texture and taste. Drying reduces the possibilities of the contamination by insects and micro-organisms so that product is prevented. An experimental study was performed to determine the drying characteristics of pineapple slices subjected to drying in cabinet tray dryer at 50°C, 60°C and 70°C with osmotic treatment indicated that T0 (Control), T1(50°Brix) and T2 (60°Brix). The entire drying process took place in the falling rate period. Drying curves were constructed using non-dimensional moisture ratio (MR) and time. Drying is the most widely used and a primary method for preservation. The result indicated that the cabinet tray dryer at 70°C was found better drying and rehydration characteristics compare to other drying temperatures.Keywords

Drying is an essential process in the preservation of agricultural products. Various drying methods are employed to dry different agricultural products. Each method has its own advantages and limitations. Choosing the right drying system is thus important in the process of drying agricultural products. An experimental study was performed to determine the drying characteristics of bael pulp subjected to drying in open sun, hot air oven at 60°C and 70°C and cabinet tray dryer at 60°C and 70°C with different varieties Pant Aparna (V1), Pant Shivani (V2) and Pant Urvashi (V3). The entire drying process took place in the falling rate period. Drying curves were constructed using non-dimensional moisture ratio (MR) and time. Drying is the most widely used and a primary method for preservation. According to the experimental result this study revealed that the V1 (Variety Pant Aparna) sample required lower drying time than the other Varieties sample. The drying time decrease with increase of drying air temperature. It was observed that drying process took place in falling rate period. The result indicated that the cabinet tray dryer at 70°C was found better drying characteristics compare to other drying temperatures and methods.Keywords
