How to process | Whey protein
Processing whey protein concentrate (WPC) powders requires specialised equipment and careful attention to hygiene, product integrity, and operational reliability. The right rotary valve plays a key role in maintaining a smooth and efficient process.
Processing WPC powder | the challenge
Whey protein concentrate is a dairy-derived powder with unique handling characteristics. WPC can be highly aerated, lightweight, and prone to build-up during conveying and storage. Maintaining consistent flow while preventing contamination and unplanned downtime can be challenging, especially in high-capacity production environments.
In modern dairy production facilities, WPC is often pneumatically conveyed from spray dryers to storage silos and packaging lines. These systems must operate continuously while complying with strict hygienic standards such as EHEDG requirements.
Why WPC is difficult to handle | hygiene and reliability
Product quality and food safety are critical in whey protein processing. Any product accumulation, seal failure, contamination risk, or excessive wear can negatively impact production efficiency and final product quality. Furthermore, maintenance interventions can be costly when production lines operate around the clock.
Because WPC powders are typically handled in hygienic environments, processing equipment must be designed for:
- Reliable and consistent product flow
- Easy cleaning and inspection
- Minimal product retention
- Reduced wear and maintenance requirements
- Protection against contamination
- Compliance with hygienic processing standards
The role of the rotary valve
A rotary valve is much more than a transfer device. It is a critical component for controlling product flow while maintaining system integrity and hygiene.
For demanding dairy applications, TBMA applies several design features that improve reliability and service life:
Guarded air lock seal | Whey protein and lactose processing often require robust sealing solutions. TBMA rotary valves can be equipped with a special labyrinth shaft seal combined with an air monitoring system. This monitoring system detects potential sealing issues at an early stage, allowing preventive maintenance before production downtime occurs.
Special low-friction rotor | The valves feature a specially designed rotor with minimal friction surfaces. This reduces wear, limits product build-up, and improves long-term operational performance.
Mobile valve execution | In critical processing positions, rotary valves can be mounted on mobile frames. This allows rapid change-out and wet cleaning outside the production environment, reducing downtime and simplifying maintenance procedures.
Hygienic integration | Combined with fluidised silo discharge systems, pneumatic conveying lines, filters, and packaging equipment, hygienic rotary valves help ensure a reliable and efficient powder handling process from spray dryer to final packaging.
Processing WPC powder efficiently | the result
When WPC is handled with the right equipment, operations benefit from:
- Increased operational uptime
- Extended service intervals
- Reduced risk of contamination
- Improved cleanability
- Consistent product quality
- Lower maintenance costs
- Reliable pneumatic conveying performance
Selecting the right rotary valve for whey protein processing directly impacts product quality, food safety, maintenance requirements, and production efficiency. With specialised rotor designs, advanced sealing technology, hygienic construction, and maintenance-friendly configurations, TBMA rotary valves provide a reliable solution for challenging WPC applications.
Choosing the right rotary valve | the takeaway
For one major dairy producer, TBMA upgraded existing production lines for whey protein and lactose powders. New hygienic rotary valves, fluidising systems, filters and conveying equipment significantly improved cleanability and increased service intervals compared to the previous installation.
Choosing the right rotary valve is not just a component decision – it is a decision that directly impacts food quality, process reliability, and operational performance.
