Technology : A Hybrid Solar-Biomass Dryer for Pineapples
The Hybrid biomass-solar dryer has a drying chamber, a biomass stove and a solar collector. The stove uses agricultural waste and a solar collector system to enhance the drying capability. The dryer is a labour enhancing technology that increases the shelf life of pineapples. 60 kg of sliced pineapples can be dried at once in one batch. With drying air temperature set at 60°C, pineapples are dried to 25% moisture content from 90% in about 12 – 16 hours. The dryer can also be used for other agricultural products such as mango, chilli and banana.
Impact : Developed in 2015, it has been tested for one month among farmer groups who have reported reduced losses in pineapples due to spoilage. There has also been the development of other products such as pineapple juice, pineapple pickle, pineapple jam, etc. The farmer groups used the dryer to dry other agricultural produce such as mango, chilli and banana.
