In modern food manufacturing, the gap between raw material and finished product is bridged by technology. For a leading publicly traded food group, this bridge was becoming a bottleneck. Specializing in the R&D, production, and sale of snack foods, their potato chip line was constrained by manual processes. High labor intensity, inconsistent metering, and significant dust pollution were not just operational headaches—they were risks to product quality and workplace safety.
To future-proof their production, the company partnered with us to deploy an integrated solution combining an automatic batching system with an efficient pneumatic transport system. This case study details how this synergy transformed their facility, delivering precision, safety, and scalability.

The Challenge: Manual Handling in a High-Volume Industry
The client’s original production line relied heavily on manual labor for ingredient management. Operators were responsible for measuring and moving materials like potato flakes, raw starch, and sugar powder. This approach introduced several critical flaws:
- Inaccuracy: Manual weighing led to batch-to-batch variation, compromising the signature taste and quality of the final product.
- Environmental Hazards: The manual handling of fine powders resulted in high airborne dust concentrations, creating an unpleasant work environment and increasing the risk of combustible dust incidents.
- Inefficiency: Transporting ingredients manually across distances of up to 60 meters was slow and labor-intensive, capping the overall production throughput.
- Safety Risks: The combination of organic dust and manual intervention in a confined space presented a serious explosion hazard.
It became evident that to meet growing market demand and ensure operational integrity, a fully automated and enclosed solution was necessary.
The Solution: Precision Batching Meets Pneumatic Conveying
We engineered a comprehensive system that addresses both the “brains” of ingredient management and the “muscle” of material movement. The solution integrates a sophisticated PLC-controlled automatic batching system with a powerful and gentle pneumatic transport system.
Designed to handle a complex mix of nine different materials—including potato flakes, raw starch, and sugar powder—the system ensures accuracy and purity without cross-contamination.
The core components of this integration include:
- Feeding Stations: 7 large ingredient feeding stations and 1 small ingredient station to segregate materials based on volume and characteristics.
- Storage & Weighing: 8 buffer storage tanks and 10 precision weighing tanks that serve as the heart of the automatic batching system, ensuring each recipe component is measured to exact specifications.
- The Pneumatic Network: Instead of manual transport, materials are moved through an enclosed pneumatic transport system over a maximum distance of 60 meters and a lift height of 3 meters, achieving a consistent conveying rate of 4 tons per hour.
The centralized PLC controller governs the entire workflow. It signals the automatic batching system when to release ingredients and directs the pneumatic transport system to move them to the next production stage. This seamless integration eliminates human error and ensures a continuous, hygienic flow of materials.
Safety by Design: Achieving Stringent Explosion-Proof Standards
A major achievement of this project is its uncompromising safety profile. In environments handling starch and sugar powders, dust explosions are a critical concern. Our integrated system was designed to mitigate these risks from the ground up.
Because the pneumatic transport system is fully enclosed, it prevents dust from escaping into the workplace. Furthermore, every critical component—from the storage tanks and dust collectors to the pipelines and control panels—is equipped with specialized explosion-proof (Ex-proof) devices.
This holistic approach to safety allowed the entire system to pass the rigorous inspections required by local safety authorities, earning prestigious explosion-proof certification. This validation provides the client with absolute confidence that both their personnel and assets are protected against potential hazards.

Results and Business Impact
Since commissioning the integrated automatic batching system and pneumatic transport system, the client has experienced a significant transformation:
- Labor Reallocation: By removing the need for manual material handling, skilled workers have been redeployed to quality assurance and process optimization roles.
- Guaranteed Consistency: The precision of the automatic batching ensures that every batch of potato chips meets the exact recipe standards, strengthening brand loyalty.
- Enhanced Safety: The enclosed nature of the pneumatic transport, combined with components, has created a clean, compliant, and safe working environment.
- Increased Throughput: With a reliable conveying capacity of 4 t/h, the production line can now operate at full capacity, easily meeting peak season demand.
Conclusion
For food manufacturers facing the dual pressures of quality control and safety compliance, integrating an automatic batching system with a pneumatic transport system offers a clear path forward. It transforms a chaotic, labor-intensive process into a streamlined, controlled, and safe operation.
If your facility handles multiple ingredients and is ready to move beyond manual processes, a customized solution can be designed to meet your specific layout and material requirements.
