Controlling the industrial crystallisation process poses a significant obstacle in the production of drugs and numerous other products. Digitisation of the crystallisation process now allows for radical change by increasing process automation to control overall crystallisation. The main pillars of Pharma 4.0 are process automation, improved control strategies, data visualisation, cloud edge storage, chemometrics, and mathematical modelling technologies. SmartCrys is a revolutionary integrated process control system that harnesses the mainstays of Pharma 4.0 with the combination of PAT tools in order to digitise the crystallisation process and achieve total process control.
