3. Process duration: When increasing the storage temperature from -40°C to -20°C for the engineering runs, a five-fold increase in process duration was observed. Similarly, simulations predict an increase in process duration of one order of magnitude when increasing the storage temperature from -40°C to -8°C for the studied sucrose solution. We study the process duration for systems at different scales in section 3.4, and reveal that the strong increase in process duration at high storage temperatures is linked to kinetic limitations of the nucleation process. Given the great interest in obtaining estimates for the process duration, we derive and test a simplified model for the prediction of this time in section 3.5.
