Zhejiang Jiaxing Food Starch Hygienic Pneumatic Conveying Case

Project Background

A food starch production facility located in Jiaxing, Zhejiang Province required a hygienic material handling solution for transferring starch powder between processing stages. The existing mechanical conveyor system led to frequent contamination risks and high maintenance costs, prompting the need for a modern pneumatic conveying approach.

Client Challenges

Starch dust particles escaped from traditional open conveyors, creating airborne contamination that endangered product safety and worker health. Frequent cleaning cycles disrupted production schedules, and the mechanical components required costly lubrication and replacement. The facility also faced stringent food safety regulations that demanded absolute dust containment and wash-down capability.

Solution Provided

An enclosed pneumatic conveying system was designed with stainless steel pipelines, positive pressure feeding, and automated control valves. The system integrates CIP (Clean-in-Place) ports for rapid sanitation, a centralized dust collector to capture fugitive particles, and variable-speed blowers to optimize energy consumption. All contact surfaces meet food-grade standards, and the pipeline layout eliminates dead zones where starch could accumulate.
