Abstract
The invention relates to a process for drying a wet film including the steps of: a) determining a desired loss on drying (LOD) for the wet film; b) determining a relationship between LOD and a rate of temperature rise of the wet film or a rate of change of the rate of temperature rise of the wet film; c) drying a wet film with continuous monitoring of the temperature of the wet film; and d) continuously adjusting one or more drying parameters to maintain the rate of temperature rise of the wet film or the rate of change of the rate of temperature rise of the wet film that produces the desired LOD.
Claims5
A process for drying a wet film comprising the steps of:
- a) Determining a desired loss on drying (LOD) for the wet film;
- b) Determining a relationship between LOD and a rate of temperature rise of the wet film or a rate of change of the rate of temperature rise of the wet film;
- c) Drying the wet film under one or more drying parameters with continuous monitoring of the temperature of the wet film;
- and
- d) Continuously adjusting said one or more drying parameters to maintain the rate of temperature rise of the wet film or the rate of change of the rate of temperature rise of the wet film that produces the desired LOD.
