Resumo: The knowledge of the physical properties of agricultural products play a relevant role in the study of industrial harvesting and postharvest processes, aiming at better equipment sizing and storage conditions. Thus, the present work aims to evaluate the effects of drying and different cultivars on the physical properties of split bean beans. Four treatments were evaluated, in which samples of fresh grain produced in the state of Paraíba and Pernambuco were submitted to the drying process for 30 h at 45 ° C and 62% relative humidity. The treatments were evaluated for the parameters water content, water activity, individual grain mass, actual and apparent specific mass, dynamic angle of repose and grain dimensions (a, b, c). porosity and grain volume. It was observed that the drying process influences the physical properties of the material, providing an increase of apparent and actual specific masses. The values of water activity, individual mass, volume, porosity, dynamic resting angle and mutually perpendicular grain dimensions decreased after the reduction of water content. The sphericity was differently influenced between treatments due to uneven shrinkage in the characteristic dimensions during the drying process.

Assim, o presente trabalho tem como objetivo avaliar os efeitos da secagem e de diferentes cultivares nas propriedades físicas dos grãos de feijão-fava rajada. Foram avaliados 4 tratamentos, nos quais as amostras de grãos in natura produzidos no estado da Paraíba e Pernambuco foram submetidas ao processo de secagem por 30 h a 45 °C e umidade relativa do ar de 62%. Os tratamentos foram avaliados quanto aos parâmetros teor de água, atividade de água, massa individual do grão, massa específica real e aparente, ângulo de repouso dinâmico e dimensões do grão (a, b, c), além de terem sido obtidos os dados de porosidade e volume do grão. Observou-se que o processo de secagem influencia as propriedades físicas do material, proporcionando um aumento das massas específicas aparente e real. Os valores de atividade de água, massa individual, volume, porosidade, ângulo de repouso dinâmico e dimensões mutuamente perpendiculares dos grãos decresceram após a redução do teor de água. A esfericidade foi influenciada de forma distinta entre os tratamentos devido ao encolhimento desuniforme nas dimensões características durante o processo de secagem.Editora Verde2019-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/681110.18378/rvads.v14i4.6811Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 No. 4 (2019); 518 - 523Revista Verde de Agroecologia e Desenvolvimento Sustentável; Vol. 14 Núm. 4 (2019); 518 - 523Revista Verde de Agroecologia e Desenvolvimento Sustentável; v. 14 n. 4 (2019); 518 - 5231981-8203reponame:Revista Verde de Agroecologia e Desenvolvimento Sustentavelinstname:Grupo Verde de Agroecologia e Abelhas (GVAA)instacron:GVAAporhttps://www.gvaa.com.br/revista/index.php/RVADS/article/view/6811/6956https://www.gvaa.com.br/revista/index.php/RVADS/article/view/6811/6939Copyright (c) 2019 Daniel Casimiro da Silveira et al.info:eu-repo/semantics/openAccessSilveira, Daniel Casimiro daLeite, Ana Carolina NóbregaSantos, Newton CarlosGomes, Josivanda Palmeira2021-06-14T13:13:06Zoai:ojs.gvaa.com.br:article/6811Revistahttps://www.gvaa.com.br/revista/index.php/RVADS/PUBhttps://www.gvaa.com.br/revista/index.php/RVADS/oairvadsgvaa@gmail.com || patriciomaracaja@gmail.com || revistaverde1@gmail.com || suporte@antsoft.com.br1981-82031981-8203opendoar:2024-03-06T12:59:37.379338Revista Verde de Agroecologia e Desenvolvimento Sustentavel - Grupo Verde de Agroecologia e Abelhas (GVAA)false
