Henan Zhongren Machinery Equipment Co., Ltd. Empowers Upgrade of Screening & Conveying System

In October 2024, Henan Zhongren Machinery Equipment Co., Ltd. entered a strategic partnership with China's largest soy milk powder contract manufacturing enterprise to deliver a customized intelligent screening and conveying system. With an annual production capacity exceeding 500,000 tons, the client demanded equipment meeting stringent hygiene standards, screening precision, and continuous operation capabilities. Leveraging its expertise in food processing machinery, Henan Zhongren developed an automated solution centered on "high-efficiency screening + sterile conveying," successfully enhancing both productivity and product quality.

The project utilized Henan Zhongren's proprietary "Integrated Pneumatic Conveying and Gravimetric Batching System," featuring:  

1.  - Ultrasonic mesh cleaning technology eliminated clogging caused by soy milk powder agglomeration, achieving 99.5% screening efficiency.  
   - 304 stainless steel construction compliant with food-grade GMP standards ensured contamination-free operations.  

2. - Closed-loop negative pressure pneumatic conveying minimized powder leakage to 0.01% throughout screening-to-packaging processes.  
   - IoT-enabled monitoring platform provided real-time tracking of flow rates, temperatures, and equipment status with auto-alert functions.  

3. - Modular design enabled rapid production line changeovers for varying particle size requirements.  
   - Single-line throughput reached 8 tons/hour, marking a 40% efficiency increase over legacy systems.  

During implementation, Henan Zhongren engineers optimized screen inclination angles and vibration frequencies to address soy milk powder's hygroscopic and adhesive properties. Anti-moisture coating technology was added to ensure long-term stability.  

Post-deployment results included:  
• 98% particle uniformity with impurities below 0.03%, exceeding industry benchmarks.  
• 70% reduction in manual intervention and 25% lower energy consumption, yielding annual savings over ¥5 million.  
• Fully enclosed design eliminated cross-contamination risks, achieving ISO 22000 certification.  

The client's project lead commended: "Henan Zhongren's system resolved chronic mesh clogging while establishing a smart foundation for future capacity expansion."  

Henan Zhongren's Project Director stated: "This collaboration exemplifies our leadership in food powder processing. We will advance ultrasonic screening technology and explore AI-driven predictive maintenance to deliver smarter, cost-effective solutions for the industry."
