PROBLEM: A leading pharmaceutical company approached Hapman for help in designing a vacuum conveyor system tailored to their needs. They required a system to transfer their finished product from a dryer to a mobile bulk bag filling system, which was scale-mounted for precise metering and batching. A critical challenge was incorporating an efficient cleaning system to completely eliminate any risk of cross-contamination during product changeovers.

SOLUTION: To address this, Hapman engineered the MiniVac™ with individually controlled spray wash ports strategically placed throughout the conveyor’s interior. This self-contained design enabled the customer to clean and sanitize the interior without the need for time-consuming external procedures. Additional time-saving features included a side access door for quick filter cartridge replacements and a clean-in-place rotary valve that allowed for easy disassembly, cleaning, and reassembly within minutes. The entire sanitary finish assembly was made from 304 Stainless Steel, with sealed motors and controls rated for explosive atmospheres and wash-down applications.

RESULT: Hapman successfully met all the company’s requirements, leading to increased efficiency and improved processing rates.
