Product quality and product safety are the guiding mantras in dairy production. That’s why the world’s leading dairy producers rely on the products and solutions developed by DMN-WESTINGHOUSE. The company’s rotary valves and diverter valves offer the highest level of precision engineering, preventing bridging and possible contamination during conveying processes. At the same time, they guarantee unparalleled cleanability, drastically increasing product safety while reducing downtime for maintenance and repairs.
Many producers of dairy products, ranging from baby formula to lactoferrin, rely on DMN-WESTINGHOUSE’s heavy-duty rotary valves. These valves come in two types and various sizes: the drop-through type (AL/AXL/AML) and the blow-through type (BL/BXL/BXXL). All product contact surfaces consist of food-grade material. They are all radiused and polished to 0,8 μm Ra (150 grit), and the rotor vanes have precisely chamfered edges preventing the build-up of conveyed dairy powders. This helps to ensure the valves comply with the stringent hygiene standards the dairy industry needs to maintain.
Cleaning intervals will vary depending on which dry dairy substances are processed. To reduce cleaning time and resulting downtime, DMN-WESTINGHOUSE has developed the MZC rotary valves based on its AL and BL series. The MZC-I and MZC-II are equipped with supporting rails so the rotor and end cover can be removed. The MZC-II opens on two sides for unprecedented easy access and superior cleanability.
DMN-WESTINGHOUSE’s valves offer a number of innovative features including Rotor Interference Detection (RID 3.0), its third generation solution for detecting unwanted contact between the rotor and body or end covers. This prevents major damage and provides insight into product contamination. RID 3.0 offers 50 times more accurate resistance measurement than its predecessors.
Shaft seal flow control boosts the reliability of its AL and BL heavy-duty rotary valve series. Precise flow control prevents the build-up of powder residue on the shaft seals, minimising the risks of seal failure, contamination, leakage, damage and downtime.
While rotary valves equipped with the Sanitary Air Seal (SAS) outboard bearing shaft seal minimise leak risks due to pressure changes inside the valve, thus maintaining the right airflow.
