Application of Three-Lobe Roots Blower in Pneumatic Conveying System at a Flour Mill
A large flour processing plant under COFCO Corporation faced multiple challenges with the screw conveyors originally used in its refining workshop: severe equipment wear, material temperature rise affecting product quality, high risk of cross-contamination, and difficulties in cleaning and maintenance. To address these issues, the plant decided to introduce an efficient and clean positive-pressure pneumatic conveying system, with the high-performance SR-N series three-lobe Roots blower as its core power equipment.
Application Scenario and Core Role
In the refining process of the flour mill, the SR-N three-lobe Roots blower is primarily used to efficiently and hermetically transport flour from unloading points (e.g., below purifiers and sifters) to designated collection bins or packaging silos. Its core function is to provide continuous, stable, and oil-free compressed air as the power source, generating a high-speed airflow that suspends flour in the pipeline and rapidly conveys it to the destination.
Solution and Advantages
Stable and Efficient Conveying Power
The structural characteristics of the SR-N three-lobe Roots blower enable it to deliver a constant flow and stable pressure, effectively overcoming resistance in the conveying pipeline. This ensures uninterrupted and stable flour transport over distances of tens or even hundreds of meters, significantly improving conveying efficiency.
Ensuring Flour Quality
The fully enclosed conveying process prevents external contaminants from entering, ensuring flour purity. Additionally, the smooth operation of the blower avoids mechanical extrusion and intense friction, effectively controlling material temperature rise and preventing flour deterioration due to overheating, thereby preserving its original taste and nutritional components.
Low Maintenance and High Cost-Effectiveness
The precision-engineered three-lobe rotors minimize wear and extend service life. Compared to traditional mechanical conveying equipment, the Roots blower requires minimal maintenance-only periodic replacement of air filters and lubricants-significantly reducing long-term maintenance costs and downtime.
Cleanliness and Automation
The entire system prevents dust leakage, improving the workshop environment and complying with food safety production standards. The system can be easily integrated with PLC control systems, enabling fully automated control from feeding to bin storage and reducing manual intervention.
Application Results
Since adopting the pneumatic conveying system with the three-lobe Roots blower as its core, the flour mill has achieved:
A 25% increase in production efficiency with significantly enhanced conveying capacity.
Stable product quality, with material loss and quality issues due to conveying virtually eliminated.
Reduced comprehensive operational costs due to decreased equipment maintenance and labor input.
A workshop environment that meets high cleanliness standards in the food industry.
Conclusion
The SR-N three-lobe Roots blower, with its stable, efficient, and clean characteristics, has become the ideal power source for modern pneumatic conveying systems in flour mills. It not only addresses the inherent challenges of traditional conveying methods but also plays a critical role in improving product quality, enabling automated production, and reducing energy consumption. This application exemplifies a successful technological upgrade in the flour processing industry.
Dry Vacuum Pumps Enable "FreshEnjoy Foods" to Achieve Efficient and Clean Vacuum Packaging Upgrade
Application Company: A large meat processing enterprise
Application Scenario: Vacuum packaging process for cooked and chilled meat products
Challenges Faced: The company previously used oil-lubricated vacuum pumps for product vacuum packaging
Encountering the following pain points in production
Oil Contamination Risk: Potential backflow leakage of vacuum pump oil could contaminate both the packaging line and products themselves, leading to complete batch rejection and compromised food safety.
High Maintenance Costs: Regular replacement of vacuum pump oil, oil filters, and disposal of waste oil not only incurred high material costs but also increased labor requirements and maintenance downtime.
Cleaning Difficulties: During production, moisture vapor and meat particles easily entered the pump, causing oil emulsification and performance degradation, necessitating more frequent maintenance and disrupting production continuity.
Solution
After technical consultation, the food enterprise decided to upgrade its core packaging line by introducing two high-power TAIKO Dry Screw Vacuum Pumps to replace the original oil-lubricated rotary vane pumps.
The TAIKO Dry Vacuum Pump, operating completely without lubricants in its working chamber, perfectly meets the stringent requirements of the food industry:
Absolute Cleanliness: Eliminates oil contamination risks at the source, ensuring absolute hygiene in product contact areas and compliance with HACCP and GMP food safety standards.
High Efficiency and Stability: Advanced screw pump technology maintains stable pumping speed, rapidly creating a high-precision vacuum environment between packaging film and products, effectively inhibiting microbial growth and significantly extending food preservation periods.
Simplified Maintenance: Requires no oil or related consumables, with daily maintenance limited to basic cleaning. The robust pump design withstands certain levels of moisture vapor and fine particulates, reducing failure rates due to process fluctuations.
Implementation Results
After three months of operation, the TAIKO Dry Vacuum Pumps delivered remarkable benefits:
Quality Improvement: Product vacuum packaging qualification rate increased to 99.8%, with zero contamination complaints attributed to vacuum pumps, strengthening brand reputation.
Cost Reduction: Achieved annual savings of tens of thousands of yuan in vacuum pump oil and filter purchases, along with hazardous waste disposal costs. Extended maintenance cycles improved production efficiency by approximately 15%.
Environmental Safety: Enabled clean production with no oil waste discharge, creating a tidier working environment while meeting increasingly stringent environmental regulations.
Conclusion:
In today's food industry pursuing safety, efficiency and sustainable development, this successful application of TAIKO Dry Vacuum Pumps demonstrates that their clean, reliable and low-maintenance advantages have made them core equipment for food vacuum packaging, degassing and conveying processes. They represent an ideal choice for driving food processing technology upgrades and ensuring safety from production line to dining table.
