SOLAR OPERATED BOILING AND DRYING MACHINE FOR TURMERIC

The after harvest unit operations for turmeric processing are boiling and drying carried out by conventional method which are slow, tedious and labour intensive.it losses are major problem of the worlds especially for developing nations where 25% of food is lost by mishandling, spoilage and pest infestation.Boiling and drying of raw turmeric rhizomes is essentially very important for development of an attractive yellow colour and aroma.solar energy is available in abundant amount in nature at free of cost. So, that we can use solar energy as option for non-renewable energy source.an appropriate technology for boiling and drying of turmeric was developed and was evaluated for the boiling and drying of turmeric rhizomes.It was observed that time required to reduced moisture content in turmeric from 79% to 10% in solar drying was 45 h while 59 h in open suns drying. Hence, it is recommended that the improved solar boiling and drying be used for turmeric processing.
