Efficient pneumatic conveying systems in food manufacturing are essential for maintaining product quality, minimizing contamination risks, and ensuring consistent production throughput. This case study highlights how a global pasta manufacturer optimized its conveying operations by leveraging tri-lobe and helical screw blower technology across multiple production stages.

Operating across more than thirty global facilities, the manufacturer prioritized oil-free blower solutions, energy efficiency, and reliability to support sustainable production. By integrating advanced blower packages into both pasta and baked goods operations, they achieved improved performance and reduced total operational costs.

Key Challenges in Pneumatic Conveying Systems for Food Industry

Food and beverage manufacturers must balance performance, hygiene, and cost when implementing pneumatic conveying systems. Key challenges include: 

  • Ensuring contamination-free air for food-safe material handling
  • Managing high-volume conveying demands without production interruptions
  • Maintaining system efficiency during variable or intermittent operation
  • Reducing energy consumption and operating expenses
  • Minimizing downtime with reliable, easy-to-service equipment

In this case, the manufacturer needed a solution capable of transporting large volumes of flour and ingredients while preserving product quality and ensuring compliance with strict food safety standards. 

Blower Technology Used in Pneumatic Conveying Systems

To address these challenges, the manufacturer implemented a combination of pneumatic conveying blowers tailored to different stages of production: 

 

Tri-Lobe Blowers for Material Transport

  • Used to convey up to 15 tons/hour of durum wheat flour from milling to storage
  • Oil-free design supports ISO 8573-1 Class 0 certification
  • Robust construction ensures reliability and reduced maintenance downtime

 

Helical Screw Blowers for Production Processes

  • Transport mixed ingredients at capacities up to 60 tons/hour
  • Deliver consistent low-pressure conveying while maintaining safe temperatures
  • Ideal for intermittent operation due to strong turndown capability

 

Expanded System Applications

  • Installed in baked goods production for conveying sugar and flour
  • Applied in wastewater treatment for aeration processes
  • Standardized across multiple facilities for operational consistency

 

Technology Advantages

  • Operates at higher pressures without compromising material integrity
  • Energy-efficient design delivers up to 20% energy savings compared to traditional solutions
  • Low wear and reduced service requirements support long-term cost savings

Key Takeaways

  • Pneumatic conveying systems in the food industry require oil-free air to meet safety standards
  • Combining tri-lobe and helical screw blowers improves flexibility and performance
  • Energy-efficient blower technology can significantly reduce operating costs
  • Reliable systems minimize downtime and maximize production throughput
  • Scalable solutions enable standardization across global manufacturing sites
  • Lower maintenance needs contribute to a reduced total cost of ownership
