Overview
The Vertical Granule Filling Machine is a vertical packaging device integrating automatic metering and filling. Specifically designed for pouch packaging of granules, chunks, flakes, and loose materials. It adopts measuring cup volumetric or electronic combination scale metering systems, combined with a vertical bag forming device, achieving fully automatic operation from bag forming, filling, to sealing. Suitable for various granular materials including nuts, seeds, pet food, candies, frozen foods, granular seasonings, and chemical granules. It is an ideal supporting equipment for automated packaging lines in the food, agricultural, and chemical industries.

Key Features

• Vertical Bag Forming System: Adopts vertical film bag forming structure, automatically completing bag forming, bottom sealing, filling, and sealing. No pre-made pouches required, reducing packaging material costs, suitable for high-volume continuous production.
• Multiple Metering Methods Available: Users can choose based on material characteristics and accuracy requirements.
• Measuring Cup Volumetric: Simple structure, high speed, cost-effective, suitable for regular granules with good flowability, accuracy ±2%~3%.
• Electronic Combination Scale: High-precision weighing, suitable for irregular or high-value materials, accuracy ±1%~2%.
• Linear Scale: For large packaging and high-dose granular materials, accuracy ±1%~2%.
• High-Precision Filling: Equipped with servo motor-driven metering system or high-precision electronic scale to ensure stable filling accuracy.
• Automatic Sealing System: Heat sealing device completes bottom seal, back seal, and top seal with attractive and secure seals. Optional gas evacuation or nitrogen filling function to extend product shelf life.
• Anti-Pinch Sealing Design: Special sealing structure design prevents granular materials from being trapped in the sealing area, ensuring seal integrity and preventing leakage.
• PLC Touchscreen Intelligent Control: Large-size HMI supporting multiple recipe storage. Filling volume, sealing temperature, running speed and other parameters can be set with one touch.
• Detection and Rejection System (Optional): Optional empty bag detection, weight checking, metal detection, and finished product rejection devices to automatically remove defective products.
• All-Stainless Steel Construction: Material-contact parts and machine body are made of 304/316L stainless steel, compliant with food hygiene standards, corrosion-resistant and easy to clean.
