Läkemedelslyofiliseringskurvprogram
After freeze-drying, biological products have certain physical forms, such as uniform color, qualified residual moisture content, good solubility, high survival rate, or long shelf life. Therefore, it is not only necessary to control the freeze-drying process and the sealed preservation after freeze-drying, but more importantly, to comprehensively control the parameters of each stage of the freeze-drying process, in order to obtain high-quality Produkter . Frystorkningskurvan och sekvensen är den grundläggande grunden för frystorkningsprocesskontroll .
The freeze-drying curve and sequence are not only the basis for manual operation of the freeze-drying machine but also the basis for automatic control of the operation of the freeze-drying machine. For example, when using the cam method and the drum method for the automatic control of the freeze-drying machine, the scribing basis of the cam and the drum is the freeze-drying curve and timing. The basis är också frystorkningskurvan och tidssekvensen, och frystorkningskurvan och tidssekvensen matas in i lagring av mikrodatorn med operationstangentbordet enligt vissa krav i mikrodatorn .
The freeze-drying curve is the relationship between the temperature and time of the plating layer in the freeze-drying box. Generally, the temperature is the ordinate and the time is the abscissa. It reflects the temperature change of the plating layer at different times during the freeze-drying process.
Frystorkningssekvensen är öppnings- och stängningsdriften för olika utrustning vid olika tidpunkter under frystorkningsprocessen .
Lyofiliseringskurvan är baserad på lamellen eftersom produkttemperaturen styrs av lamelletemperaturen . som styr lagartemperaturen också styr produkttemperaturen .
