Otimização de trocadores de calor do tipo placas para microcervejarias

Abstract

The great competition that exists between the companies of the industrial sector makes the market more competitive. The food industry presents several processes, such as refrigeration, freezing, pre-treatment, pasteurization, among others. For the microbreweries sector, the pasteurizing process is carried out from plate-type heat exchangers, which can be optimized to reduce resource costs, as water. Also, the plate-type heat exchangers can optimize the process parameters to lower the manufacturing cost. The objective of this work is to perform the analytical modeling of a plate-type heat exchanger and optimize it by reducing its cost of production and minimizing the use of the cooling fluid. In this study, four heat exchangers were designed, where three of them were optimized. The best option among the four proposals was the optimized exchanger in order to obtain a lower manufacturing cost, together with a decrease in the use of cold fluid.
