Automatic Vertical Granule/Powder Packaging Machine
The Automatic Vertical Granule/Powder Packaging Machine represents a state-of-the-art vertical form-fill-seal (VFFS) solution, meticulously engineered for the high-speed, precise packaging of small-dose granules and compatible fine-flow powders. At its core lies a robust Inovance PLC and color touch screen control platform, orchestrating intelligent film feeding, servo-driven bag pulling, pneumatic filling, and reinforced heat sealing. This synergy ensures consistent bag aesthetics, superior seal integrity, and rapid changeovers for varying bag lengths. Constructed with GMP principles and utilizing corrosion-resistant materials for all product-contact surfaces, the machine is ideally suited for demanding hygienic production environments where dependable performance, repeatable accuracy, and operational efficiency are paramount.
Core Product Advantages
Intelligent Control & Operational Reliability
Centralized control via an Inovance 7-inch color touch screen and PLC enables intuitive operation, comprehensive fault diagnostics, and prompt alerts, significantly minimizing downtime. Precise thermal management is guaranteed by a Yuian 4-channel PID temperature control module, with all parameters conveniently displayed and adjustable on the main interface for optimal sealing consistency.
High-Precision Bag Formation & Dosing
An Inovance servo motor drives the bag-pulling mechanism, ensuring exceptional tracking precision and accurate bag length control, switchable between color mark tracking and fixed-length modes via the touch screen. Synchronized pneumatic filling, also from Inovance, delivers accurate, repeatable doses with excellent corrosion resistance, maintaining stable feeding synchronization with the main unit across all operational speeds.
Enhanced Sealing Integrity & Quality
The servo-controlled, reinforced heat sealing system operates with low noise while producing clear, strong seals. Optimized for composite aluminum film, the three-side sealing process ensures consistent transverse and longitudinal seal patterns. The sealing width is adjustable within a 5–7 mm range, offering process flexibility for diverse packaging requirements.
Streamlined Adjustment & Changeover
Product changeovers are simplified with an independent rotating cutter for easy bag length adjustments. The metering system features a handwheel lead-screw adjustment with a precision dial, allowing for swift and repeatable setup—a critical advantage for small-batch or multi-product small-dose production runs.
Hygienic & Durable Construction
Built for stringent environments, the machine’s exterior utilizes 304 stainless steel with anti-corrosion coating. All material-contact parts are fabricated from food-grade plastic and 316 stainless steel, aligning with pharmaceutical GMP standards. The electrical cabinet employs a compressed-air ventilation structure to enhance internal cleanliness and component longevity. Reliability is further assured by the use of premium electrical components from brands such as Schneider and OMRON.
