: In India there is separate market for fruit production and export but most of the fruits are seasonal so drying plays an important role in fruit production and preservation. Processed food market is about 30-35 % of total food industry in India. Drying of agricultural product is important considering their original nutritional values and properties. Raisins are one of the important dried fruit throughout the world. Conventional drying methods needs more energy and more drying time and can be reduced by hybrid drying methods with good quality and less drying time period. Microwave drying is best solution because of severe reduction in drying period and the quality of final product. Any individual drying technique doesn’t fulfill the all requirements so hybrid drying becomes important with combinations of drying technology. In this work microwave convective hot air dryer is developed and experimentation of drying parameters done by response surface methodology for optimization of drying parameters such as microwave power density, hot air temperature carried out on developed lab scale model.
