- Product Description
-
The degassing packaging machine is a specialized equipment designed for high-air-content, fluffy powders. It is available in two configurations: vertical-screw degassing and horizontal-screw degassing. By integrating screw feeding with mechanical or vacuum-based degassing, this machine effectively removes entrapped air from the material, increases bulk density, and prevents ton bags from bulging or collapsing during transport. It is a core solution for packaging high-air-content powders in the lithium-battery and chemical industries.
The horizontal screw degassing packaging machine features a triple-degassing system comprising large- and small-diameter horizontal screw feeding, mechanical extrusion degassing, and vacuum-assisted degassing. After coarse feeding by the large screw, the material is mechanically compressed by an extrusion plate to expel most of the entrapped air; during fine feeding by the small screw, a vacuum system removes any remaining air. Finally, strong bottom vibration combined with cylinder-driven bag-shaking compaction ensures superior degassing performance compared with vertical-screw models, making it ideal for ultra-high-air-content, highly fluffy powder materials. The equipment emphasizes gravimetric weighing and metering, and comes standard with air-bag bag clamping, automatic hook release, dual dust collectors, and a triple-degassing system. The lithium-battery-specific version is tailored for core lithium-battery materials such as lithium iron phosphate and graphite powder, producing densely packed ton bags that can be directly stacked and palletized, fully compatible with automated packaging lines.
