Resumo: For an economical and safe design of vertical silos, factors such as the flow pattern that interfere with the distribution of loads in the silo, need to be carefully evaluated. Thus, the main objective of this research was to analyze the influence of the inverted cone insert, on the characteristics of the poultry feed flow in a vertical silo. The flow characterization experiment was conducted at the Seed Processing Laboratory, the flow properties, granulometry and moisture content determined at the Rural Construction and Ambience Laboratory - LACRA, both from the Federal University of Campina Grande, Campina Grande - PB. A longitudinally sectioned cylindrical silo with dimensions of 1.1m in height and 0.45m in diameter was used, representing a silo with an H / D ratio of 2.4, and a hopper 0.5 m high and 70º inclined to the horizontal, with 0.06 m discharge hole. The influence of the insert was evaluated in three different positions in relation to the discharge orifice: 0.35; 0.45 and 0.55 m. The feed presented difficulty in the flow, presenting the formation of cohesive arc, developing funnel flow, with several falls during its unloading, causing shocks in the silo structure, with the use of inverted cone insert, the formation of cohesive arc was not observed, changing the flow pattern of the stored product to mass.

Así, el objetivo principal de esta investigación fue analizar la influencia del insert de cono invertido, sobre las características del flujo de alimento de las aves en un silo vertical. El experimento de caracterización de flujo se realizó en el Laboratorio de Procesamiento de Semillas, las propiedades de flujo, granulometría y contenido de humedad se determinaron en el Laboratorio de Ambiente y Construcción Rural - LACRA, ambos de la Universidad Federal de Campina Grande, Campina Grande - PB. Se utilizó un silo cilíndrico seccionado longitudinalmente con dimensiones de 1,1 m de altura y 0,45 m de diámetro, lo que representa un silo con una relación H / D de 2,4 y una tolva 0,5 m de altura y 70º inclinado a la horizontal, con orificio de descarga de 0,06 m. La influencia del inserto se evaluó en tres posiciones diferentes en relación al orificio de descarga: 0,35; 0,45 y 0,55 m. El alimento presentó dificultad en el flujo, presentando la formación de un arco cohesivo, desarrollando un flujo en embudo, con varias caídas durante su descarga, provocando choques en la estructura del silo, con el uso de un insert de cono invertido, no se observó la formación de un arco cohesivo. , cambiando el patrón de flujo del producto almacenado a masa.Para um projeto econômico e seguro de silos verticais, fatores como o padrão de fluxo que interferem na distribuição de cargas no silo, precisam ser criteriosamente avaliados. Desta forma, o objetivo principal desta pesquisa foi analisar a influência do insert de cone invertido, nas características do fluxo de ração avícola em silo vertical. O experimento de caracterização de fluxo foi conduzido no Laboratório de Beneficiamento de Sementes, as propriedades de fluxo, a granulometria e o teor de umidade determinadas no Laboratório de Construções Rurais e Ambiência- LACRA, ambos da Universidade Federal de Campina Grande, Campina Grande - PB. Foi utilizado um silo cilíndrico seccionado longitudinalmente de dimensões de 1,1m de altura e 0,45 m de diâmetro, representando um silo com relação H/D igual a 2,4, e uma tremonha com 0,5 m de altura e inclinação de 70º com a horizontal, com 0,06 m de orifício de descarga. A influência do insert foi avaliada em três diferentes posições em relação ao orifício de descarga: 0,35; 0,45 e 0,55 m. A ração apresentou dificuldade no fluxo, apresentando a formação de arco coesivo, desenvolvendo fluxo em funil, com várias quedas durante seu descarregamento, provocando choques na estrutura do silo, com a utilização de insert de cone invertido, não foi observado a formação de arco coesivo, alterando o padrão de fluxo do produto armazenado para mássico.Research, Society and Development2020-11-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1036910.33448/rsd-v9i11.10369Research, Society and Development; Vol. 9 No. 11; e63091110369Research, Society and Development; Vol. 9 Núm. 11; e63091110369Research, Society and Development; v. 9 n. 11; e630911103692525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/10369/9179Copyright (c) 2020 Diego José Araújo Bandeira; José Jefferson da Silva Nascimento; José Wallace Barbosa do Nascimentohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBandeira, Diego José Araújo Nascimento, José Jefferson da SilvaNascimento, José Wallace Barbosa do 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/10369Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:26.456936Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
