A powder manufacturer in Langfang, Hebei, faces a serious problem of cross-contamination among different types of powder during production. The company mainly produces various medicinal powders. Due to frequent batch changes, residual powders lead to reduced product purity, increasing quality risks and rework costs. Head Powder combined field inspections and process analysis to customize a complete chemical powder cross-contamination prevention system for the company, addressing common industry challenges.

Core pain points for customers

The customer faces the following prominent issues in production: First, it is difficult to thoroughly clean internal residues from the equipment, and when switching between different product types, it is easy for powders from previous batches to be mixed in; Second, traditional conveying processes operate openly, causing dust leakage and environmental pollution and cross-contamination; Third, there is a lack of systematic isolation and monitoring methods, with high reliance on manual operations that cannot help maintain consistency. These issues directly affect product pass rates and production efficiency.

Head Powder Solutions

To address these pain points, Head Powder has designed a complete system centered on closed pneumatic conveying, equipped with high-efficiency cleaning devices and intelligent control modules. The system adopts a modular structure, allowing key contact parts to be quickly disassembled and cleaned without dead corners, reducing residue risk. At the same time, through dual designs of positive pressure sealing and negative pressure recovery, dust leakage is eliminated, helping different types of powder to be fully isolated during transportation. This system is already operating normally at the Langfang customer's site, helping the customer achieve continuous production and improving product qualification rates.
