Solving the Aeration Paradox: Engineering Two-Stage Degassing for Ultrafine Powder Packaging

Published on: January 14, 2026 | By Jialong Engineering Dept.

Handling materials with high air retention, such as lithium battery cathode powders or fine chemicals, requires a departure from standard gravity filling. A conventional powder packaging machine often fails to remove interstitial air, leading to unstable packaging. The engineering solution is the ultrafine powder packing machine, which integrates a sophisticated two-stage degassing mechanism. By employing both pre-evacuation and mechanical shaping, this advanced vacuum packaging machine technology solves the "fluidization" problem inherent in micrometer-scale particles.

Core Mechanism: Two-Stage Vacuum Degassing

The primary distinction of an ultrafine powder packing machine is its ability to handle gas-solid separation. The process begins with pre-evacuation to -0.06 MPa to remove free air. Crucially, a secondary screw extrusion phase combined with negative pressure adsorption reaches -0.095 MPa. This deep vacuum cycle, executed by the automatic vacuum packing machine, achieves a degassing efficiency exceeding 98%. As a packaging machine manufacturer, we calibrate these vacuum levels to ensure powder integrity is maintained while bulk density increases by 30%-50%. Standard powder packaging machine designs lack this dual-stage capability.

Mechanical Shaping and System Standards

Following degassing, the vacuum packaging machine utilizes a six-sided mold with vibration assistance. This aligns the particles into a rigid, cuboid structure. Unlike general powder packaging machine units, an ultrafine powder packing machine requires 316L stainless steel contact parts or food-grade PTFE coatings to prevent corrosion and sticking. Our automatic vacuum packing machine systems also integrate pulse back-blow dust removal, keeping leakage below 1mg/m³, a critical safety standard for any packaging machine manufacturer.
