Testing of Hybrid Solar-Biomass Dryer for Drying Fish

In this study, we have developed and tested a solar energy dryer unit equipped with biomass-fueled air heater. The drier which has been made consists of a drying chamber length of 260 cm and width of 80 cm, with glass as cover. The dryer is equipped with a crossflow type heat exchanger for air heaters by utilizing biomass fuel. In this test used 25 kg of dried fish starting the morning at 09:00 to 16:00 utilizing solar energy, from 16: 00-06: 00 using hot air maintained at temperature 40-50oC. From the test results obtained, after reaching 22-23 hours of drying, the weight of the fish did not change much, and it can be stated that the fish has dried at the final weight of 12.5 kg.本研究开发并测试了一款配备生物质燃料空气加热器的太阳能干燥装置。该装置的干燥室尺寸为长260厘米、宽80厘米，以玻璃作为覆盖材料。装置采用错流式换热器结构，配套以生物质为燃料的空气加热器。本次试验中，于上午9:00至16:00利用太阳能对25千克待干燥鱼进行干燥作业，16:00至次日06:00则采用维持在40~50℃的热空气继续干燥。试验结果表明，当干燥时长达到22~23小时后，鱼体重量不再发生显著变化，此时最终干重为12.5千克，可判定鱼体已完成干燥。
