Controlled freeze drying keeps the product temperature low enough during the process to avoid changes in the dried product appearance and characteristics.

Once a target product temperature is identified (typically several degrees colder than the critical temperature), the only two variables left to determine/control are the shelf temperature and system vacuum level. Special containment systems such as glove boxes are required for freeze drying certain products, especially when toxic materials are present. Understanding the physical properties of materials that are freeze-dried is a key part in developing a successful lyophilization process. A piece of aluminum foil can be hung liofilizacion pdf in front of the product on the inside of a pilot freeze dryer as a shield of course this will block the view of the product and not allow observation during the process.
