Description
Mixing operation system using agitated vessels design is a difficult task challenge for high viscosity liquid mixtures. The bi-direction impeller design proven to have great impact to the mixture’s homogeneity. The use of Computational Fluid Dynamics (CFD) provide detail understanding for such operation system. Experimental test and computational fluid dynamics simulations were performed in this study to examine the flow characteristic of two impeller designs i.e. anchor and Rushton turbine, in achieving solution for liquid paste-type homogeneity. The impeller was used to mix gelatin (isoionic point of 5), an alkali-treated precursor type with warm water. The study objectives are to improve the impeller design for dry granule gelatin mixing machine; to find optimum velocity distribution pattern value for liquid-paste type homogeneous mixtures and to remain even dissolve mixtures. The method used in this study are House of Quality (HOQ) analysis and CFD method. The findings are used to provide basis for scale up mixing operation and choosing the best mixing equipment for larger systems.
