This article presents a detailed engineering case study of an antistatic pneumatic conveying system designed for milk powder production in Saskatchewan, Canada. The project was supplied by Shandong Headpowder Engineering Co., Ltd., abbreviated as Headpowder, a Chinese engineering company located in Shandong, China. With growing demand for safe, hygienic, and efficient powder handling in the North American dairy industry, Headpowder was engaged to deliver a complete pneumatic conveying solution that could handle milk powder without contamination, dust explosion risk, or product degradation. This case illustrates how modern dilute-phase pressure conveying technology can be adapted to meet strict North American standards and the specific challenges of milk powder.

Milk powder is a fine, light, and easily charged material. During conveying, particles collide with pipe walls and with each other, generating static electricity. If not controlled, static charge can cause powder to adhere to pipelines, create blockages, reduce flow efficiency, and, more critically, trigger sparks capable of igniting combustible dust. Therefore, the key focus of this Saskatchewan project was the antistatic design of the entire conveying route. Headpowder used stainless steel pipes with continuous electrical continuity, reliable grounding connections, and antistatic filter media in the receiver hoppers. The system also included proper bonding across flanges and flexible connectors, ensuring that every component was at the same electrical potential and that accumulated charge was safely dissipated to the earth.

The pneumatic conveying system was designed to transfer milk powder from spray drying and collection equipment to storage silos, and then to packaging lines. The conveying process uses a positive displacement blower to generate compressed air, which carries the milk powder through the pipeline in dilute phase. This gentle conveying mode reduces the risk of particle breakage and keeps the powder’s physical properties intact. The system was also equipped with an advanced PLC control unit that monitors pressure, airflow, and filter differential pressure in real time. All process parameters can be displayed on a touchscreen interface and integrated with the plant’s existing automation network. This allowed the North American client to operate the system with minimal manual intervention and to maintain accurate batch records.

The project demonstrates Headpowder’s capability to execute international engineering projects in North America. Before delivery, the company conducted a detailed material test using milk powder samples to determine the minimum conveying velocity and the optimum air-to-solid ratio. This helped avoid excessive velocity, which could generate more static electricity and damage the powder structure. The final design included a velocity control strategy with variable frequency drives and pressure sensors along the line. Additionally, the system was equipped with explosion relief panels and a fast-acting isolation valve to protect downstream equipment. These safety features align with recognized international standards and local Canadian requirements for combustible dust handling.

Another important element was hygienic design. Milk powder is a food product, so all contact parts were made of 304L stainless steel with a smooth internal surface finish. The welds were polished to eliminate dead spaces where bacteria or powder residues could accumulate. The conveying air was filtered with high-efficiency particulate air filters to ensure that the product remained free from airborne contaminants. The system was designed to be cleaned easily; it supports disassembly and manual cleaning as well as connection to a clean-in-place system for specific components. This combination of hygiene and antistatic safety made the solution particularly suitable for dairy applications in Canada, where food safety inspection is rigorous.

From the perspective of project management, Shandong Headpowder Engineering Co., Ltd. provided complete engineering services including process design, equipment manufacturing, factory acceptance testing, shipping, installation supervision, and commissioning. The company, based in Shandong, China, has extensive experience in powder handling systems for food, chemical, and mineral industries. For this Saskatchewan milk powder project, Headpowder worked closely with the client’s local engineering team to ensure compliance with Canadian electrical codes and equipment standards. The project was delivered on schedule, and the client reported significant improvements in production efficiency, reduced product loss, and safer working conditions.

In conclusion, the Saskatchewan milk powder antistatic pneumatic conveying case demonstrates the importance of tailored engineering in powder handling. The successful collaboration between Headpowder and the Canadian customer proves that Chinese engineering companies can offer high-quality, antistatic pneumatic conveying solutions for the North American market. With the increasing demand for milk powder and other dairy ingredients in North America, the reliability, safety, and hygienic performance of such conveying systems will remain crucial. Headpowder continues to support customers in Canada and the United States with dedicated after-sales service and technical consulting.
