Moreover, in order to optimize the freeze drying process and product quality, it is vital. Generally, the freeze drying process is done in three steps, under vacuum: freezing, primary and secondary drying.

That single vent allows for the escape of water vapor during the process.

Biological materials often are dried to stabilize them for storage or distribution. Accordingly, the lyophilization process of the pharmaceutical field will be explained in this section. This process normally consists of three stages : (1) freezing. Lyophilization also called.
