Pneumatic conveying scheme for sodium metabisulfite

In traditional manual feeding or mechanical transportation, sodium metabisulfite often faces issues such as severe dust dispersion, material moisture and clumping, heavy labor intensity for workers, and substandard environmental conditions. At the same time, because this material is hygroscopic and generally corrosive, traditional equipment is prone to clogging and rapid wear, resulting in high maintenance costs. Enterprises urgently need a sealed, efficient, and low-damage automated conveying solution to improve production efficiency and meet environmental protection requirements.

Material characteristics

Sodium metabisulfite is a white or pale yellow crystalline powder, easily soluble in water, with strong reducing properties. It easily oxidizes and decomposes in humid air, releasing sulfur dioxide. Its particles are fine, have average fluidity, are prone to moisture absorption and caking, and generally corrode metals. Therefore, the conveying system must have good sealing, moisture resistance, and corrosion-resistant materials, while avoiding material breakage or temperature rise caused by high-speed airflow.

Product Introduction

The sodium metabisulfite pneumatic conveying system provided by Head Powder uses positive pressure dilute or dense phase conveying methods, custom-designed according to material characteristics and on-site conditions. The system consists of air source equipment, feeding devices, conveying pipelines, dust separation and removal devices, and automated control systems, achieving a fully enclosed and automated operation process from feeding to storage. Pipes are treated with corrosion-resistant stainless steel or special linings, and valves and seals are made of corrosion-resistant materials to effectively address material characteristics. The control system can integrate weighing and weighing, remote monitoring, and other functions, helping to improve conveying accuracy and operational stability.

Product advantages

To address customer pain points, this solution achieves the following improvements:
· Fully enclosed conveying eliminates dust leakage and improves workshop environment;
· Equipped with moisture-proof and anti-caking devices to improve material flowability;
· Automated control reduces manual intervention and lowers labor intensity;
· Corrosion-resistant design extends equipment lifespan and reduces downtime and maintenance;
· The conveying process is smooth, reducing material breakage and temperature rise, and maintaining consistent quality.
