Patent attributes
A continuous feed lyophilizer drying chamber that has an overall internal volume, a primly drying stage portion having a primary drying stage internal volume, a secondary drying stage portion having an internal volume, a frozen formulation feed inlet that provides frozen formulation droplets into the internal volume of the primary drying stage of the drying chamber and a dried particle outlet proximate an end of the continuous feed lyophilizer drying chamber configured to provide dried formulation droplet particles. The primary drying stage typically makes up from about 65-75% of the overall internal volume of the drying chamber and the secondary drying stage makes up from 25 to 35% of the overall internal volume of the drying chamber. The drying chamber dries frozen formulation droplets received into the primary drying stage internal volume via the frozen formulation feed inlet.
