Resumo: | The present work aims to evaluate a low cost direct exposure solar drying system, easy to operate, accessible to family farmers and of high efficiency that uses desiccant for drying air in the city of Campina Grande - PB. The methodology used consisted in the construction of two dryers of identical characteristics and dimensions, which, when experimentally tested, one of them was (integrated) to a desiccant unit (desiccant chamber) while the other was without a chamber. The outlet temperatures obtained in the dryers with and without desiccant chambers were close, different from the value of the relative humidity of the air. The average relative humidity of the drying air recorded was approximately 16.8% in the dryer with desiccant, while in the dryer without desiccant the average was approximately 17.6%. The collected data allowed the realization of the energy balance of the solar dryer, resulting in the calculation of the thermodynamic efficiency of the solar dryers, which was on average 38.89% for the dryers with desiccant and 36.93% for the dryer without desiccant. The average mass efficiency of the drying process was around 99% for the dryer with desiccant and 98% for the dryer without desiccant. Finally, it was possible to conclude that the use of desiccant materials can help to improve the thermal performance of an equipment, and that bentonite was the most efficient desiccant compared to charcoal and rice. |

La metodología utilizada consistió en la construcción de dos secadores de idénticas características y dimensiones, los cuales al ser probados experimentalmente uno de ellos estaba (integrado) a una unidad desecante (cámara desecante) mientras que el otro no tenía cámara. Las temperaturas de salida obtenidas en los secadores con y sin cámaras desecantes fueron cercanas, diferentes al valor de la humedad relativa del aire. La humedad relativa promedio del aire de secado registrada fue de aproximadamente 16,8% en el secador con desecante, mientras que en el secador sin desecante el promedio fue de aproximadamente 17,6%. Los datos recolectados permitieron la realización del balance energético del secador solar, dando como resultado el cálculo de la eficiencia termodinámica de los secadores solares, que fue en promedio 38,89% para los secadores con desecante y 36,93% para el secador sin desecante. La eficiencia de masa promedio del proceso de secado fue de alrededor del 99 % para el secador con desecante y del 98 % para el secador sin desecante. Finalmente, se pudo concluir que el uso de materiales desecantes puede ayudar a mejorar el desempeño térmico de un equipo, y que la bentonita fue el desecante más eficiente en comparación con el carbón vegetal y el arroz.O presente trabalho tem como objetivo avaliar um sistema de secagem solar de exposição direta de baixo custo, fácil operação, acessível aos produtores da agricultura familiar e de elevada eficiência que utiliza dessecante para o ar de secagem na cidade de Campina Grande – PB. A metodologia utilizada consistiu na construção de dois secadores de características e dimensões idênticas, que, quando testadas experimentalmente, um deles estava (integrado) a uma unidade dessecante (câmara dessecante) enquanto o outro estava sem câmara. As temperaturas de saída obtidas nos secadores com e sem câmara dessecante foram próximas, diferente do valor da umidade relativa do ar. A média de umidade relativa do ar de secagem registrada foi de aproximadamente 16,8% no secador com dessecante, enquanto no secador sem dessecante a média foi de aproximadamente 17,6%. Os dados coletados possibilitaram a realização do balanço de energia do secador solar, resultando no cálculo do rendimento termodinâmico dos secadores solares, o qual foi em média 38,89% para os secadores com dessecante e 36,93% para o secador sem dessecante. A média da eficiência mássica do processo de secagem ficou em torno de 99% para o secador com dessecante e 98% para o secador sem dessecante. Por fim, foi possível concluir que o uso de materiais dessecantes pode auxiliar na melhora do rendimento térmico de um equipamento, e que a bentonita foi o dessecante mais eficiente comparativamente ao carvão vegetal e arroz.Research, Society and Development2022-07-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3177510.33448/rsd-v11i9.31775Research, Society and Development; Vol. 11 No. 9; e43011931775Research, Society and Development; Vol. 11 Núm. 9; e43011931775Research, Society and Development; v. 11 n. 9; e430119317752525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/31775/27360Copyright (c) 2022 João André Soares e Sousa da Conceição; Marcelo Bezerra Grilo; Vitor Leão Santana; Jonas Fernando de Souza Fernandes; Ítalo de Andrade Gomes; Nancy Lima Costa; Arnaldo Bezerra Lopes de Almeida; Nórton Leornardo Teodório Rafael; Wellington Souza Lima ; Allan Willian Luduvico de Aquinohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessConceição, João André Soares e Sousa daGrilo, Marcelo Bezerra Santana, Vitor Leão Fernandes, Jonas Fernando de SouzaGomes, Ítalo de AndradeCosta, Nancy LimaAlmeida, Arnaldo Bezerra Lopes de Rafael, Nórton Leornardo TeodórioLima , Wellington Souza Aquino, Allan Willian Luduvico de 2022-07-21T12:36:16Zoai:ojs.pkp.sfu.ca:article/31775Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:00.349106Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
