Resumo: The fish feed is the main cost of production in fish farming, and thus feed management must be carried out accurately, avoiding waste. One way to gain more control is through automation. This study aimed to evaluate different types of automatic feeders, two commercial (AC1 and AC2) and a prototype developed by Epagri. For each model, tests were performedevaluating four feed particle sizes (1.3mm; 2.5mm; 4-5mm, and 6-8mm), with different levels of hopper filling (full, medium and empty), and with supply times of 1, 3, 5, 10, 20 and 30s. The parameter evaluated was the accuracy of feed supply (g),represented by the mean observed error (K). The prototype was effective in supplying all feeds, the commercial AC1 feeder was not suitable for 1.3mm diets, and the AC2 feeder only worked for 4-5mm and 6-8mm feed sizes. The test results make itpossible to conclude that the prototype developed by Epagri showed good accuracy, as well as the commercial models evaluated, in addition to being effectve for all evaluated feed particle sizes.

Uma forma de obter maior controle é através da automatização. Este estudo objetivou avaliar diferentes tipos de alimentadores automáticos de eixo helicoidal, dois comerciais (AC1 e AC2) e um protótipo desenvolvido pela Epagri. Para cada modelo foram realizados testes avaliando quatro granulometrias de rações (1,3mm; 2,5mm; 4-5mm, e 6-8mm), com diferentes níveis de enchimento do silo (cheio, médio e vazio), e com tempos de fornecimento de 1, 3, 5, 10, 20 e 30s. O parâmetro avaliado foi a acurácia no fornecimento de ração (g), representado pelo erro médio observado (K). O protótipo foi eficaz no fornecimento de todas as rações, já o alimentador comercial AC1 não foi adequado para dietas de 1,3mm, e o alimentador AC2 funcionou apenas para as granulometrias de 4-5mm e 6-8mm. Os resultados dos ensaios possibilitam concluir que o protótipo desenvolvido pela Epagri apresentou uma boa acurácia, assim como os modelos comerciais avaliados, além de ser eficaz para todas as granulometrias avaliadas.Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina - Epagri2022-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://publicacoes.epagri.sc.gov.br/rac/article/view/145610.52945/rac.v35i3.1456Agropecuária Catarinense Journal; Vol. 35 No. 3 (2022); 52-56Agropecuária Catarinense; v. 35 n. 3 (2022); 52-562525-60760103-0779reponame:Agropecuária Catarinense (Online)instname:Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)instacron:EPAGRIporhttps://publicacoes.epagri.sc.gov.br/rac/article/view/1456/1445Copyright (c) 2022 Raphael de Leão Serafini, Bruno Corrêa da Silva, Haluko Massago, Natalia Marchiori, André Luís Tortato Novaeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSerafini, Raphael de Leãoda Silva, Bruno CorrêaMassago, HalukoMarchiori, NataliaNovaes, André Luís Tortato2022-12-26T14:31:16Zoai:ojs.publicacoes.epagri.sc.gov.br:article/1456Revistahttps://publicacoes.epagri.sc.gov.br/RAC/indexPUBhttps://publicacoes.epagri.sc.gov.br/index.php/RAC/oaieditoriarac@epagri.sc.gov.br || lamperuch@epagri.sc.gov.br2525-60760103-0779opendoar:2022-12-26T14:31:16Agropecuária Catarinense (Online) - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina (Epagri)false
