Introduction

Continuous processing is a promising approach for solid dosage manufacturing. High-shear wet granulation is performed in continuous mode using twin screw granulators (TSG), characterized by a modular screw profile including a sequence of different screw elements with various shapes, orientation and functions. For process engineers it is a challenge to come up with prediction models to establish the relationship between equipment and material attributes, process data and the end-product testing results. If a reliable model is available which is able to predict the quality of the product, it can be inverted to obtain the design space, corresponding to that set of operating conditions required for achieving the target product quality (Figure 1). Such a modelling framework combined with in-process measurements, can provide a good mechanistic insight into the important parameters of continuous
