Resumo: | The present study aimed to observe the rheological behavior of goat milk at different concentrations (20, 25, 30, 35 and 40%), subsequently evaluating which concentration is most suitable for the milk drying process. It was observed that at all milk concentrations, the shear stresses are low and increase when the strain rate also increases. Such behavior is typical of a non-Newtonian fluid. This fact occurs mainly at the 40% concentration, which is the one with the highest viscosity. It is clear that a higher concentration requires a higher stress to initiate the flow, since the initial shear stress is a function of the concentration. It was also observed that the more concentrated milk will have the flow in the pumps of the drying process more difficult, requiring more energy to travel. It was observed that the three adjustment models analyzed, Bingham, Ostwald-waelw and Herschel-Buckley can be used for the product in question, as they all reached excellent R², above 0.99, with Ostwald-waele being the one that presented even better results. The flow index (n), in the Ostwald-waele model, did not show large variations between concentrations, ranging from 1.295 to 1.469, however, always higher than 1, which indicates that the fluid is considered to be dilating. It was also noticed that with the increase in concentration, there is a distancing of the values of n from the unit, deviating from the ideal. |

Se observó que en todas las concentraciones de leche, los esfuerzos cortantes son bajos y aumentan cuando también aumenta la velocidad de deformación. Tal comportamiento es típico de un fluido no newtoniano. Este hecho ocurre principalmente a la concentración del 40%, que es la de mayor viscosidad. Está claro que una concentración más alta necesita un esfuerzo mayor para iniciar el flujo, ya que el esfuerzo cortante inicial es una función de la concentración. También se observó que la leche más concentrada tendrá el flujo en las bombas del proceso de secado más difícil, requiriendo más energía para viajar. Se observó que los tres modelos de ajuste analizados, Bingham, Ostwald-waelw y Herschel-Buckley pueden ser utilizados para el producto en cuestión, ya que todos alcanzaron una excelente R2, por encima de 0,99, siendo Ostwald-waele el que presentó mejores resultados. . El índice de flujo (n), en el modelo de Ostwald-waele, no mostró grandes variaciones entre concentraciones, oscilando entre 1.295 y 1.469, sin embargo, siempre superior a 1, lo que indica que se considera que el líquido se está dilatando. También se advirtió que con el aumento de concentración, se produce un distanciamiento de los valores de n de la unidad, desviándose del ideal.O presente estudo teve como intuito observar o comportamento reológico do leite de cabra em variadas concentrações (20, 25, 30, 35 e 40%), avaliando posteriormente qual concentração é mais adequada para o processo de secagem do leite. Observou-se que em todas as concentrações do leite, as tensões de cisalhamento são baixas e aumentam quando a taxa de deformação também aumenta. Tal comportamento é típico de um fluido não newtoniano. Esse fato ocorre principalmente na concentração de 40%, que é a que possui maior viscosidade. É notório que uma concentração maior necessita de uma maior tensão para iniciar o escoamento, visto que a tensão inicial de cisalhamento é em função da concentração. Foi observado também que o leite mais concentrado, terá o escoamento nas bombas do processo de secagem mais dificultoso, necessitando de maior energia para deslocar-se. Observou-se que os três modelos de ajuste analisados, Bingham, Ostwald-waelw e Herschel-Buckley podem ser utilizados para o produto em questão, pois todos alcançaram R² excelentes, acima de 0,99, sendo o de Ostwald-waele o que apresentou resultados ainda melhores. O índice de fluxo (n), no modelo de Ostwald-waele, não apresentou grandes variações entres as concentrações, oscilando de 1,295 a 1,469, contudo, sempre superior a 1, o que indica que o fluido é considerado como dilatante.
