Abstract:

Use of non-renewable energy sources for drying of agricultural products is an expensive process at rural scale. Drying for agricultural products are one of the most attractive and cost effective application of solar energy. Therefore an appropriate technology for drying of agricultural products has been developed and its performance for drying of turmeric rhizomes has been evaluated. A forced convection solar dryer was developed. The system is capable of generating an adequate and continuous flow of hot air temperature between 55-600C. The turmeric rhizomes were successfully dried in the developed solar dryer. Turmeric rhizomes were dried with pretreatment (boiling in water for 30 min). Experimentation was carried out on boiled turmeric rhizomes with forced convection and with natural convection in the same set up. The experimental analysis showed that the natural convection solar drying takes 8 days (considering 9 sunshine hours from 10am to 6pm). Whereas forced convection drying required 6 days (considering 9 sunshine hours from 10am to 6pm) for drying of turmeric rhizomes. It is observed that turmeric dried in solar dryers take lesser time to reach the safe level of moisture content for storage when compared to open sun drying and the quality of turmeric produced are far more superior.
