Rotary coating system GS EVOLUTION

filmlaboratoryfor the pharmaceutical industry

Overview
GS EVOLUTION is a solid-wall coating pan designed for tablet film coating, sugar coating and powder layering for pellets and microgranules. Built for highly automated and contained installations, the machine minimizes operator exposure to potent products and can be configured at multiple automation levels to match production needs.

Highlights

• Optimised pan geometry and surface finish plus a patented drying system for uniform coating distribution and efficient solvent removal.
• High flexibility with interchangeable paddle sizes to adapt pan working capacity and product requirements.
• Two pan configurations (standard or spiralled) enable automatic product and water discharge to simplify operation and cleaning.
• Sealed processing area using inflatable seals on front and rear doors to contain the process and reduce operator exposure.
• Immediate, validated cleaning: automatic CIP cycle can start after production; water discharge via bottom outlet or high-efficiency discharging spiral.

Machine versions
Lab Version: laboratory-scale coating pan for R&D with an interchangeable drum (solid-wall or fully perforated). Typical drum working batches: 0.5–30 L depending on drum; an option for very small batches (0.5–2 L) is available. Laboratory units use the same core technology as production models to support scale-up and process transfer.
