Avaliação de diferentes tipos de impelidores na taxa de transferência de calor e tempo de mistura em um biorreator de bancada

Abstract

The stirred tank bioreactor is the most used industrially in fermentation processes catalyzed by enzymes or living cells. To determine the heat transfer rate and the mixing time of different types of impellers in a bench reactor, a study was carried out on mechanical agitation tanks, for the later presentation of the heat transfer and mixing time calculations. This knowledge of technical data, promoted improvements in the efficiency of the project, reduction of expenses, optimization of time (mixing, stabilization of temperature and pH), and reduction in the cost of the process. In global terms, the data obtained suggested which impeller model is the most suitable for the bioprocess, justified by the parameters of heat transfer rates and mixing time.
