Recent Development of Ghe Solar Drying in Indonesia

Adapting Drying Technologies for Agri-Food Market Development in India

“…The desiccant unit permits continuation of the drying process during the off-sunshine hours to maintain product quality. Abdullah et al [5] proposed a greenhouse effect solar dryer for the drying of tropical fruits. Their results show that it is possible to achieve better drying efficiency with their solar dryer, which would be useful for most of the developing countries where abundant solar energy is available.…”

Solar Drying Technology in Indonesia: an Overview

“…Drying efficiency was 18 to 55%. For 48.8 kg of banana jerky, SDT took only 5.1 h for reduce moisture content from 60.4% (wb) to 26.8 (wb) with biomass fuel, but took 8.6 h for reduce moisture content from 63.6% (wb) to 25.4 (wb) without biomass fuel [85], [86]. The moisture content of cassava decreased to 10.5% from 61% (wet basis) within 9 and 13 h at average temperatures of 45 °C and 40 °C by using SAHPD and solar dryer, respectively.…”

“…The pickup efficiencies and SMER were 44% and 39% and 0.47 and 0.38 kg/kWh for SAHPD and solar dryer, respectively [87]. Prototypes of greenhouse effect (GHE) solar dryer have been tested and their technical performances for chili, fermented cocoa beans, coffee berries, banana, papaya, sliced meat, seaweed, fish and it has great potential for application in the rural areas of Indonesia as shown in Table 3 [88]. A simple test with 70 kg seaweeds showed that the product could be dried to a final weight of 12 kg within two days while smelt fishes (stolephorus family) with initial weight of 65 kg could be dried within 7 hrs, under drying temperature of 51 o C. Other purpose of technology dissemination was to train the local people so that they are capable in constructing, operating and administrating the facility.…”

Other purpose of technology dissemination was to train the local people so that they are capable in constructing, operating and administrating the facility. As negotiations on with local food industry, new opportunities was explored to make use of the facility to dry vegetables, and to export dried marine products such as seaweed and fishes to overseas market [88].…”
