Mechanical Dispersion Of A Semi-Solid Binder In A Wet Granulation Process, Justin W. Perry, James D. Litster, Nathan J. Davis
The Summer Undergraduate Research Fellowship (SURF) Symposium
High viscosity surfactant pastes have recently gained popularity in the production of high efficiency laundry detergents due to their ability to increase surfactant loading in granules. When using high viscosity semi-solid binders a unique challenge is presented because it forces granules to be formed primarily by mechanical dispersion; a relatively poorly understood process. Developing mechanistic models of this process will enhance knowledge of mechanical dispersion processes and improve process development for granules produced using this method. Experiments to determine the effect of three process parameters; paste temperature, impeller RPM, and time were carried out in a lab-scale granulator. Binder temperature …
