“Continuous Lyophilization Spray” likely refers to a method or process that combines aspects of continuous spray drying and lyophilization (freeze-drying).
- Continuous Spray Drying: Spray drying is a technique used to turn a liquid or slurry into a dry powder by spraying the material into a hot gas stream. This rapid drying process creates small particles of the dried substance. Continuous spray drying involves a continuous flow of the liquid or slurry into the drying chamber, which allows for a constant production of dried material.
- Lyophilization (Freeze-Drying): Lyophilization is a dehydration process typically used to preserve perishable materials or make them more convenient for transport or storage. It involves freezing the material and then subjecting it to a vacuum environment to remove the ice by sublimation, bypassing the liquid phase. This results in a dry product with minimal damage to its structure.
Combining these techniques into “Continuous Lyophilization Spray” likely entails a continuous process where a liquid or slurry is sprayed into a chamber where it is rapidly frozen and then subjected to vacuum drying to remove the frozen solvent, ultimately producing a dry powder or product. This process might be advantageous for certain applications where continuous production and preservation of sensitive materials are required.
