A powdered sugar processing enterprise in Changzhou, Jiangsu Province faces dust pollution issues during the delivery of powdered sugar during production. Dust fills the workshop, causing not only raw material waste but also affecting employee health, and posing safety risks from dust explosions. Traditional conveying methods can no longer meet increasingly stringent environmental and safety requirements.

Customer pain points

The company's powdered sugar features small particle size, easy lifting, and strong moisture absorption. During gravity dropping and open conveying, severe dust dispersion leads to:

• Raw material loss rate exceeds 5%, with significant annual loss costs;
• Workshop cleanliness does not meet standards, requiring employees to frequently wear protective equipment;
• Dust concentration approaches the lower explosive limit, posing high safety risks;
• Equipment accumulated dust becomes blocked, requiring frequent shutdowns for cleaning, affecting production efficiency.

Solution

Our company designed a complete dust-free pipeline conveying system tailored to the characteristics of the company's powdered sugar. The system adopts a fully enclosed negative pressure pneumatic conveying principle, ensuring no leakage throughout the entire process from feeding and conveying to storage. Key components such as the inner walls of pipes undergo special polishing to prevent powdered sugar from sticking; The air source uses high-efficiency filters to help discharge air meet standards. After project implementation, workshop dust concentration dropped below 0.5mg/m³, meeting national occupational health standards.

Product advantages

This dust-free piping system offers the following values:

• Zero leakage conveying:Fully welded or flanged sealed connections, ensuring seamless gaps and no dust escape;
• Low Energy Consumption:Optimized gas-solid ratio design, reducing unit energy consumption by more than 20% compared to traditional systems;
• Intelligent Control:Equipped with a PLC automatic adjustment system, it can adapt conveying speed according to material characteristics;
• Easy-to-maintain structure:The pipeline uses quick-opening maintenance openings, with cleaning intervals extended to once per quarter.

Implementation Results

Actual operational data shows that the customer's powdered sugar loss rate dropped from 5% to within 0.3%, workshop cleanliness met the 300,000-level standard, and equipment downtime caused by dust issues was reduced by 90% throughout the year. At the same time, the system passed the special acceptance by the local environmental protection department, providing similar powdered sugar processing enterprises with replicable dust-free transformation solutions.
