Producing a lyophilized pharmaceutical material involves injection of a solution of the material into a vertical freezer pipe and precipitation of the resulting ice particles by gravity

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent describes a method for producing lyophilized (freeze-dried) pharmaceutical materials. The process involves injecting the liquid pharmaceutical solution in the form of droplets into a vertical freezer pipe under vacuum conditions, where the droplets freeze and fall due to gravity. The ice particles are then collected for further drying. The patent also covers equipment (a plant) designed to carry out this process.

Use CasesContent extracted from patent full text and abstract with AI.

• Manufacturing of freeze-dried drugs or vaccines for increased shelf-life and stability

Patent Abstract

Producing a lyophilized pharmaceutical material involves injection of a solution of the material in droplet form into an evacuated vertical freezer pipe, precipitation of the resulting ice particles by gravity, and collection of them for a drier pipe. An independent claim is also included for a plant for implementation of the proposed method.
