Areas of application
LEWA metering pumps are used, for example, for:
- Aqueous solutions, suspensions and emulsions
- Compositions based on organic solvents, such as ethanol, isopropanol, acetone or methylene chloride
Filler, binder, disintegrants, sliding agents can thus be dissolved or suspended and transferred with the active material in defined, dry, free flowing, uniform particles.
Background
The fundamental concept of spray drying
The production of finely dispersed powder from a wet charging fluid by vaporizing the liquid:
- A solution /suspension is sprayed via nozzles or rotating disk atomizers into a hot air or nitrogen flow
- The supply to the spray drying system uses suitable pumps. Drying and particle formation are done simultaneously in the spraying process during this process. Due to these higher requirements on the pharmaceutical technology, the demands which are put on the bioavailability of a drug also increase. The effectiveness of a drug also depends on the generated particle size, after all.
Important customer requirements for this are:
- Particle size distribution
- Percentage of residual moisture
- Bulk density and particle shape
- Maintaining exact and consistent quality standards
- Precise, continuing, safe and
- low-pulsation fluid supply
