云南师范大学能源与环境科学学院王云峰教授等在国际知名期刊《Renewable Energy》发表最新研究成
2023年9月11日,Elsevier 旗下国际著名期刊《Renewable Energy》在线发表了云南师范大学能源与环境科学学院王云峰教授课题组的最新研究成果《Drying characteristic, sustainability, and 4E (energy, exergy, and enviro-economic) analysis of dried date fruits using indirect solar-electric dryer: An experimental investigation》。云南师范大学能源与环境科学学院王云峰教授通讯作者。
An indirect solar-electric dryer (ISED) was constructed to valorize the date surplus under drying temperatures of T = 50–65 °C. The effective moisture diffusivity (Deff) values of dates were 4.59 × 10−7, 5.58 × 10−7, 7.29 × 10−7, and 1.04 × 10−6 m2 s−1, respectively, for 50, 55, 60, and 65 °C with convective mass transfer coefficient ranging between 9.18 × 10−7 and 2.08 × 10−6 m s−1. The drying behavior of date fruits using ISED was described by Wang and Singh's model with 99.98% alignment with experimental data. The lowest specific energy consumption (SEC) was 3.71 kWh.kg−1 resulting in T = 65 °C. The highest solar energy fraction (63.2%) and the lowest electric energy fraction (36.8%) were obtained under 60 °C drying temperature. The highest exergy efficiency (ηEx = 73%) was attained at 50 °C. The highest waste exergy ratio and the lowest sustainability index 0.39 and 2.54, respectively were obtained for T = 65 °C. The improvement potential factor increased with the decrease in ηEx and varied between 17.1 and 64.7. Low CO2 emissions amount of 17.23 kg/year was reached, and impressive payback period values of 0.26, 0.25, 0.12, and 0.08 years were estimated, respectively, for T = 50, 55, 60, and 65 °C. The ISED under 65 °C drying temperature is recommended for date fruits.
