Challenge
A leading pharmaceutical manufacturer needed a vacuum conveying system to transfer finished product from a dryer to a mobile, scale-mounted bulk bag filler for precise batching. The primary challenge was ensuring complete cleanability to eliminate any risk of cross-contamination during product changeovers — a critical requirement in pharmaceutical processing.
Solution
Hapman engineered a Vacuum Conveyor equipped with individually controlled spray wash ports strategically located throughout the interior. This feature enabled automated, thorough cleaning and sanitization without external disassembly.
To further simplify maintenance, the system included a side access door for fast filter cartridge replacement and a clean-in-place rotary valve that could be disassembled, cleaned, and reassembled within minutes.
The entire sanitary assembly was built from 304 Stainless Steel with sealed motors and controls rated for explosive and wash-down environments, ensuring compliance with stringent pharmaceutical standards.
Results
The custom vacuum system met all performance and cleanliness requirements, enabling faster product changeovers, reduced downtime, and improved process efficiency while maintaining the highest standards of product purity.
