Improving dry powder handling in food processing

This case study explores how the adoption of the Ebro ViDOS Vibrating Dosing Valve addressed key challenges faced by a food processing plant by providing good sealing, dosing and product integrity.

Efficiency and precision are crucial in the industry, especially when it comes to dry powder handling. This case study focuses on a food processing facility with a dry powder vacuum loader above a process mixer that required a valve to isolate the two vessels.

The plant faced three primary challenges:

1. Achieving a reliable seal between the vessels for tight shut-off.
2. Ensuring accurate and precise dosing of the powder.
3. Minimising product degradation.

Traditional solutions such as rotary airlocks and screw feeders fell short of meeting these requirements. To overcome these challenges, the food processing plant adopted the EBRO ViDOS Vibrating Dosing Valve which provided it with advantages over conventional butterfly valves, rotary airlocks and screw feeders in terms of performance, accuracy and space efficiency.

The solution provides compact dimensions without compromising accuracy or repeatability. Its integration of a 4–20 mA positioner and a mounted vibrator allowed controlled flow at low feed rates and precise filling of containers.
