Anhui Wuhu edible powder antimicrobial contamination transportation project

A certain food processing company has long relied on traditional mechanical conveying methods for feeding, transportation, and packaging of edible powder raw materials. The company's production workshop has extremely high environmental cleanliness requirements, especially to prevent the growth and spread of microorganisms during transportation. The original equipment frequently had excessive microbiological testing standards due to many structural dead corners and insufficient sealing, seriously affecting production efficiency and product quality stability.

Customer pain points

1.High risk of microbial contaminationTraditional conveying equipment has material residues and cleaning dead spots. After powder remains in pipelines for a long time, bacteria and mold can easily grow, leading to excessive bacterial counts in finished products.
2.Cleaning is difficult: The production line requires daily CIP cleaning, but the original equipment is complex to disassemble and the inner walls are rough, making thorough cleaning impossible, increasing labor costs and downtime.
3.Product quality fluctuates: Due to the uncertainty of microbial contamination, product quality varies from batch to batch, affecting the stable delivery of customer orders.

Solutions and product advantages

To address these pain points, Head Powder provided the company with a customized pneumatic conveying system for edible powder. This system uses a fully enclosed pipeline design, allowing materials to be transported under positive or negative pressure in a sealed environment, completely preventing the intrusion of external microorganisms. The inner wall of the pipe is mirror-polished, with a surface roughness of Ra≤0.4μm, effectively reducing powder adhesion and facilitating quick cleaning. At the same time, the system is equipped with an online cleaning interface and an automatic sewage discharge device, reducing the frequency of manual intervention.

At a critical stage, Head Powder introduces a gas sterilization filtration unit to preprocess the gas source, helping to keep the conveyed medium itself sterile. Additionally, the system adopts a modular structure, supporting quick disassembly and sterilization verification, meeting GMP standards for the food industry. After implementation, the company's microbial testing pass rate for products increased to over 99.5%, production line changeover time was shortened by 60%, and overall operation and maintenance costs dropped by about 30%.
