Despite obtaining good dispersion results in the lab, the challenge of unstable quality upon mass production occurs in many settings. The main cause of this is that the dispersion conditions are not replicated due to differences in scale. In lab equipment, the smaller size leads to higher energy density, making shear and flow more uniform, while in mass production equipment, the larger scale often results in insufficient dispersion energy at the same rotational speed and processing time. Additionally, differences in equipment structure and flow patterns can cause variations in the shear history and residence time experienced by particles, leading to differences in the dispersion state. Furthermore, simple scale-up does not ensure that critical parameters such as flow rate, residence time, and shear intensity match, making it difficult to reproduce the same results as in the lab. To address these challenges, it is essential to focus on process design based on dispersion energy density and flow conditions rather than merely increasing equipment size. By designing the system so that particles pass through the processing area under consistent conditions, it is possible to achieve reproducible dispersion quality even when the scale changes, as seen in inline continuous processing.

In dispersion processes, the variation in quality is one of the significant challenges. Even when processing under the same equipment and conditions, it is not uncommon for the dispersion state to differ from batch to batch. The main factor behind this is the variability in the dispersion history experienced by the particles. In batch processing, the shear and residence time experienced by each particle differ depending on their position and flow state within the tank. As a result, there is a mixture of sufficiently dispersed particles and undispersed particles, leading to variations in quality. This tendency becomes particularly pronounced under high viscosity or high solid content conditions. On the other hand, in continuous processing, particles pass through a consistent processing area, receiving nearly the same dispersion conditions. Because shear energy and residence time can be controlled consistently, the variability in dispersion history is minimized, resulting in a uniform and highly reproducible dispersion state. Moreover, continuous processing is advantageous during scale-up. By adjusting the flow rate, it becomes easier to replicate similar dispersion quality from the lab to mass production. This helps reduce the risk of quality fluctuations during the transition from development to mass production. What is crucial in dispersion processes is to provide the same processing history to all particles. Continuous processing easily meets this condition and is an effective method for stabilizing quality and ensuring reproducibility.
