Assessment of a beeswax-packed domestic solar dryer for sustainable bitter gourd drying: An experimental study
Solar dryers present a clean and affordable solution to food wastage which is one of the biggest concerns of the world. The highest contribution of domestic sector to the global food waste and lack of researches on small-scale solar dryers have created a need to develop sustainable and low cost domestic solar dryers. The present research aims to develop and analyse the output behaviour of a beeswax-packed domestic solar dryer (BDSD) for intermittent bitter gourd drying. The drying kinetics of bitter gourd slices and thermal, economic, environmental and exergetic performances of the BDSD have been evaluated with varying sample masses for passive and active drying conditions. The average final moisture content of the bitter gourd slices for passive and active conditions were found to be 3.26 and 3.93 % (wb), respectively. Midilli-Kucuk model exhibited the strongest fit to the bitter gourd drying behaviour under both the drying conditions. The total moisture evaporation, heat transfer coefficients, thermal efficiency, specific moisture extraction rate, savings for dried bitter gourd slices drying, CO2 mitigation, carbon credit earned and exergy efficiency were found to increase while the drying rate, effective moisture diffusivity, specific energy consumption, costs for bitter gourd slices drying, payback period and energy payback time decreased as the sample mass increased under both drying conditions. The performance of the BDSD was found to be a linear function of sample mass under both drying conditions.
期刊介绍:
Official Journal of the European Federation of Chemical Engineering:
Part C
FBP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering and science dedicated to the safe processing of biological products. It is the only journal to exploit the synergy between biotechnology, bioprocessing and food engineering.
Papers showing how research results can be used in engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in equipment or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of food and bioproducts processing.
The journal has a strong emphasis on the interface between engineering and food or bioproducts. Papers that are not likely to be published are those:
• Primarily concerned with food formulation
• That use experimental design techniques to obtain response surfaces but gain little insight from them
• That are empirical and ignore established mechanistic models, e.g., empirical drying curves
• That are primarily concerned about sensory evaluation and colour
• Concern the extraction, encapsulation and/or antioxidant activity of a specific biological material without providing insight that could be applied to a similar but different material,
• Containing only chemical analyses of biological materials.
