The Automatic Granule Packaging Machine is a high-efficiency rotary premade-pouch packing system engineered for fast, stable, and hygienic packaging of free-flowing granules. Built around an 8-station intermittent rotary workflow, it integrates bag feeding, opening, filling, dust control assistance, sealing, and discharge into one coordinated cycle—delivering consistent bag presentation and reliable seal quality for both food and non-food applications. For full automation, the machine can be matched with an optional Z-Type Bucket Conveyor to realize continuous material lifting, steady feeding, and cleaner production through integrated dust/sand/iron removal functions.
Product Introduction
Designed for modern production lines that demand speed, flexibility, and repeatable quality, this rotary premade-bag solution supports a wide range of pouch formats such as flat bags, stand-up pouches, zipper bags, and M-type bags. Its controlled rotary motion and station-by-station synchronization help maintain stable operation at high throughput, while precise temperature management and coordinated sealing action enhance package integrity across different bag materials. The electrical and pneumatic architecture adopts industrial-grade components to improve uptime, simplify troubleshooting, and support long-term continuous running.
When combined with the optional Z-type conveyor, the system becomes a complete granule packaging line: product is lifted from a hopper, conveyed upward in buckets, and delivered at a regulated rate to match packaging speed. This reduces manual handling, minimizes spillage, and supports cleaner feeding—especially helpful for dusty, sandy, or mixed granules.
Product Features
High-speed rotary performance: An optimized 8-station rotary cycle supports production speeds up to 72 bags/min, enabling high-volume output while maintaining consistent process timing and repeatability.
Broad premade-bag compatibility: Handles multiple pouch styles—including flat, stand-up, zipper, and M-type—helping manufacturers switch products or upgrade packaging formats without frequent machine replacement.
Reliable sealing with process stability: Controlled sealing temperature and coordinated actuation improve seal strength and appearance across single PE, composite films, paper films, and multi-layer laminates, reducing leakage risk and rework.
Industrial electrical configuration: Key control and safety positions utilize well-known component brands for stable performance, clearer maintenance logic, and improved long-term uptime in demanding production environments.
Automation-ready feeding integration: The optional Z-type bucket conveyor with variable-frequency speed regulation delivers steady, adjustable feeding to match packaging rhythm and reduce overfeed, underfeed, and spillage.
Cleaner, more durable material handling: The optional conveyor is manufactured in 304 stainless steel and includes dust/sand/iron removal functions, supporting cleaner production and reducing wear or contamination risks.
