Vacuum Drying

LACO designed a vacuum drying system to meet a medical device manufacturer's unique process requirements. The sensitive device had very tight requirements for temperature exposure and liquid saturation times. The system was able to reduce the drying time by over a factor 5 times while maintaining product dryness uniformity. The flexibility of the system allowed the customer to also perform significant process development to optimize the drying process.

Key Features

• Multiple platens/shelves controlled over a temperature range of -30 to +75 C, with +- 0.5 C temperature uniformity.
• Cryogenic cooled condenser to trap water vapor.
• Dynamic pressure control system to precisely control the drying rate.
• Vacuum chamber with external oven/heater control to 100 C.
• Heated inert gas purge system with internal gas distribution manifold.
• Flexible software to allow the customer to build his own customized automated drying sequences.
• Dry vacuum pump for long life and trouble free operation.
