Resumo: | Pulsed electric field (PEF) systems should be designed to be microbiologically and energy efficient for industrial applications applied to treatment of different types of liquid foods. A thorough numerical model for the design of PEF systems is presented. It takes into account two combined approaches, a field evaluation based on an electric-thermal-fluid dynamic analysis and a design of numerical experiment considering as variables the applied high voltage and the internal electrode radius of a coaxial geometry. Then, the survival ratio and the specific energy are solved as conflicting objectives for the PEF design, using the treatment time and pulse frequency from the coupled analysis. The formulation is applied for grape and orange juices with E. coli for single and multiple stages systems. The simulations with multiple stages for the grape juice showed that it is possible to reach a microbial inactivation of 3.1 (log10 scale of survival rate) with a specific energy of about 450kJ/kg lower in relation to a two stage system. It means an energy reduction of 92, 421kJ/h for a treatment system with a capacity of 163 L/h. |

Um modelo numérico completo para o projeto de sistemas PEF é apresentado. Leva em consideração duas abordagens combinadas, uma avaliação de campo baseada em uma análise eletrotérmico-fluidodinâmica e um planejamento de experimento numérico considerando como variáveis a alta tensão aplicada e o raio interno do eletrodo de uma geometria coaxial. Em seguida, a taxa de sobrevivência e a energia específica são resolvidas como objetivos conflitantes para o projeto do PFE, utilizando o tempo de tratamento e a frequência de pulso da análise acoplada. A formulação é aplicada para sucos de uva e laranja com E. coli em sistemas de estágio único e múltiplo. As simulações com múltiplos estágios para o suco de uva mostraram que é possível atingir uma inativação microbiana de 3,1 (escala log10 de taxa de sobrevivência) com uma energia específica cerca de 450kJ/kg inferior em relação a um sistema de dois estágios. Significa uma redução energética de 92.421kJ/h para um sistema de tratamento com capacidade de 163 L/h.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorengUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA ELÉTRICAIET Science Measurement & TechnologyCampos elétricosSuco de laranjaSuco de uva - indústriaAplicações industriaisPulsed electric field systemsLiquid foodsIndustrial applicationsNumerical modelNumerical study of treatment chambers for single and multistage pulsed electric field systemsEstudo numérico de câmaras de tratamento para sistemas de campo elétrico pulsado simples e multiestágioinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://ietresearch.onlinelibrary.wiley.com/doi/10.1049/smt2.12040Eduardo Jose de AraujoIvan Jose da Silva LopesJaime Arturo Ramírezapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/62014/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALNumerical study of treatment chambers for single and multi-stage pulsed electric field systems.pdfNumerical study of treatment chambers for single and multi-stage pulsed electric field systems.pdfapplication/pdf1115404https://repositorio.ufmg.br/bitstream/1843/62014/2/Numerical%20study%20of%20treatment%20chambers%20for%20single%20and%20multi-stage%20pulsed%20electric%20field%20systems.pdfe5c77046428f2e380b2b6764064be44aMD521843/620142023-12-14 17:37:17.033oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-12-14T20:37:17Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
