Corkidi Ingeniería Four drop sizes phase system bubble sizes image acquisition Multiphase mixing is a common operation in fermentation process. However, one of the main problems for onlineautomatic monitoring of dispersions occurring in microbial cultures in a mechanically stirred bioreactor, isthe difficulty in acquiring images (in motion) clear enough to characterize its elements (mainly air, water, oiland biomass) and their interactions during cultivation. Once the images to be analyzed have been acquired,other problems arise related to the complexity and diversity of objects/artifacts captured in the visual field. Theheterogeneous transparency of some objects, low contrast and similarity between different classes of objectsare, among others, major problems for the automation of image analysis procedures. The purpose of thiswork is to present a system that allows the on-line acquisition of images inside a mechanically stirred tank.The images are digitally obtained by connecting a TV camera to a stereomicroscope. The scanning of thecamera is synchronized to the flashing of a stroboscope, which acts as the light source and is equipped with asubmergible probe. These illumination conditions allow obtaining high quality images that can be furtheranalyzed to quantify size distributions of air bubbles and oil drops in multiphase dispersion, and to observe thedynamics of phase interactions (solid, liquid and gaseous) in a model culture. 2003 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47400107 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.1 |
