Resumo: In this work, a transient model for a conveyor dryer used in gelatin drying is made through mass and energy balances, being initially considered three hypotheses for the equilibrium isotherm and two for the drying rate. The option about these equations was done through the model’s fitness to typical operation values with the main process variables measured coming with a small portion of gelatin. An experiment done to get the drying curve suggests the gelatin drying happens in only one phase. As a result, the model uses the Henderson’s isotherm and a single phase expression for the drying rate. Model simulation’s results at process conditions show it is able to represent the main trends of process.

A definição dessas expressões foi realizada pelo ajuste do modelo aos dados de uma situação típica de operação com as principais variáveis do processo medidas pelo acompanhamento de um lote de gelatina ao longo do secador. Um ensaio, em laboratório, foi realizado para se obter a curva de secagem, indicando que a secagem da gelatina ocorre essencialmente em uma fase. Assim, o modelo utiliza a isoterma de Henderson e uma expressão para a taxa de secagem de apenas uma fase. Os resultados da simulação do modelo nas condições do processo demonstram que esse é capaz de representar as principais tendências do processo.Universidade Estadual De Maringá2008-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/218010.4025/actascitechnol.v25i2.2180Acta Scientiarum.
