Dense phase vacuum conveying for fragile powders
Efficiently convey fragile powders without compromising their integrity, optimized for seamless integration into your production line, ensuring minimal product breakdown and maximum process control.

Gently Conveys and Protects Fragile Powders
The RELCO® Dense Phase Vacuum Conveying System from Kovalus Separation Solutions is expertly engineered to handle the delicate task of conveying fragile powders such as whey protein, milk powder, and infant formula without damaging their structure. This system employs a controlled vacuum operation that precisely manages powder velocity and pressure, preventing powder stalling and optimizing movement through short to medium distances.
Specifically designed for dairy, food, beverage, and life sciences industries, the system operates with instantaneous rates up to 60,000 kg/hr, ensuring high throughput and efficiency. With a compact convey line size compared to lean phase systems, the dense phase technology minimizes product breakage, making it ideal for heat-sensitive and abrasive powders.
Fully automated, the system integrates seamlessly into existing production lines, with a PLC-controlled interface for effortless operation and the potential for remote monitoring. Its stainless steel construction ensures material compatibility and longevity, while easy-access components support quick cleaning and maintenance. Additionally, options for customization are available to meet specific production needs, backed by engineering support from Kovalus experts.
