This case study describes a hygienic pneumatic conveying system for food starch in Lae, Papua New Guinea. It is a representative pneumatic conveying case in the Oceania region, delivered by Shandong Headpowder Engineering Co., Ltd., also known as headpowder. The company is based in Shandong, China, and specializes in powder handling systems, including dilute-phase and dense-phase conveying, dust control, and process equipment. For this project, headpowder designed a complete solution that satisfied strict hygienic requirements and improved production efficiency.

Food starch is fine, light, and easy to become airborne. If it is handled manually or transported in open equipment, dust leakage, material loss, and cross-contamination can easily occur. The customer in Lae needed a safe and sanitary method to move starch from storage and sifting to mixing, weighing, and packaging stations. The starch is a food ingredient, so all contact surfaces had to be food safe and simple to clean. This called for a hygienic conveying system rather than a conventional industrial conveyor.

Headpowder selected a sealed vacuum pneumatic conveying system for the plant. A vacuum pump creates negative pressure, and the starch is drawn through sanitary stainless steel pipes from the feed point to the receiving vessel. The product remains fully enclosed during transfer, which prevents dust escape and protects it from moisture and foreign matter. The contact parts are made of food-grade stainless steel with smooth internal surfaces. The pipes use hygienic clamps and polished bends without dead corners, so starch accumulation is minimized and cleaning is fast. The receiving equipment includes a hygienic filter that separates powder from the conveying air, ensuring stable airflow and clean exhaust.

The system is automated with a PLC and a touchscreen operation panel. The operator can set the conveying amount, adjust the speed, and monitor pressure and filter status in real time. The control program includes filter pulse cleaning, overload protection, and alarm functions. With this automation, the starch plant reduces labor costs and avoids inconsistent manual operations. The enclosed line also keeps dust levels close to zero, creating a much safer working environment and shortening the time needed for daily cleaning.

After the project was put into operation, the plant achieved several benefits. Product quality is more consistent because starch has less contact with air, moisture, and handling stresses. Raw material losses are significantly reduced, and the risk of contamination is smaller. The quiet and energy-efficient operation lowers production costs. The system also makes food safety audits easier because the equipment can be inspected and cleaned properly. The entire installation has maintained stable performance since commissioning, and the maintenance staff can service most components without special tools. The success of this case shows how a hygienic pneumatic conveying system can bring real value to food processing plants in Oceania.

Shandong Headpowder Engineering Co., Ltd. supported the entire process, from detailed design and manufacture in Shandong to shipping and installation supervision in Papua New Guinea. The headpowder engineers also commissioned the system and trained local operators. Remote technical support was arranged to ensure smooth long-term operation. This Lae project demonstrates headpowder’s ability to carry out hygienic conveying projects for food starch and other powders in international markets.
