Abstract

An efficient continuous-type solar-biomass powered grain-dryer coupled with thermal storage mediums (sensible and latent) has been developed for small-scale farmers. Thermodynamic analysis of the developed dryer has been performed for performance optimization. This investigation comprises the energy and exergy examination of paddy drying of 12 kg capacity for the moisture content reduction of 20.4 % (34.2 % to 13.8 %). Thermal storage mediums, such as pebbles and paraffin wax, are used to maintain stable temperature during the drying process in the chamber of a biomass-based dryer. In this analysis, two batches of paddy (12 kg/batch) were successfully dried in each drying mode (solar and biomass operating mode). Solar energy was used in paddy drying during the daytime and biomass energy during the night. The improvement potential and sustainability index of dryer under solar drying have also been evaluated. The environmental impact analysis of the dryer has also been conducted.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
