Automatic Premade Pouch Packaging Line with 10-Head Multihead Weigher and 8-Station Rotary Pouch Packing Machine
Share to:
This automatic granular premade pouch packaging line integrates a Z-bucket elevator, stainless steel access platform, 10-head multihead combination weigher, and 8-station rotary premade pouch packaging machine for high-speed, precision-controlled packaging. Designed for free-flowing granules and irregular products, the system achieves accurate multihead weighing (±0.5–1g) and stable pouch filling up to 2000g. Equipped with Delta PLC control, SMC/AirTac pneumatic components, ribbon date coding, and intelligent pouch detection, the line is ideal for nuts, snacks, pet food, seeds, hardware, and chemical granules.
Machine Overview and Functional Description
The automatic premade pouch packaging line for granular products is engineered for manufacturers requiring high-speed, accurate, and visually premium packaging using premade pouches. The complete system consists of a Z-type bucket elevator, walk-on maintenance platform, 10-head multihead combination weigher, and an 8-station rotary premade pouch packaging machine, delivering synchronized weighing and filling performance.
The process begins with a food-grade Z-bucket elevator, equipped with durable polypropylene buckets for gentle product conveying, minimizing material breakage during transfer. Product is elevated to a heavy-duty operator platform with anti-slip grating and stainless safety guardrails, ensuring safe inspection and maintenance access.
Material is then distributed into the 10-head multihead weigher, featuring independent weighing hoppers, centralized discharge funnel, automatic vibration amplitude adjustment, and intelligent weight combination algorithms. The system achieves high-speed dynamic weighing accuracy of ±0.5–1g, supporting both weight-based and count-based filling modes. An optional anti-breakage vertical agitator is available for fragile products such as nuts, chips, and puffed snacks.
After precise weighing, product is discharged into the 8-station rotary premade pouch filler, which automatically completes pouch pickup, date coding, zipper opening, pouch opening, filling, sealing, and finished pouch discharge in one continuous cycle. If pouch pickup fails or the pouch is not properly opened, the system automatically suspends filling and sealing to prevent product waste.
Powered by Delta PLC and touchscreen HMI, with SMC/AirTac pneumatic systems and food-grade SUS304 contact parts, the entire line ensures reliable operation, low maintenance cost, and compliance with international food production standards.

FAQs
1. What products can this premade pouch packaging line package?
This automatic premade pouch packaging line is suitable for a wide range of granular, free-flowing, and irregular products, including nuts, roasted snacks, seeds, rice, pet food, frozen food, coffee beans, candy, hardware parts, fertilizer granules, detergent particles, and chemical pellets. The maximum product size is generally recommended to be smaller than large walnuts for stable feeding and weighing accuracy.
2. What pouch types are compatible with the rotary premade pouch packing machine?
The 8-station rotary pouch packaging machine supports multiple premade bag formats, including stand-up pouches (doypack), zipper pouches, flat premade bags, three-side seal bags, four-side seal bags, and gusset pouches. Bag width and height can be adjusted according to customer requirements.
3. What weighing accuracy can the 10-head multihead weigher achieve?
The 10-head combination weigher delivers high-speed precision weighing with an accuracy of approximately ±0.5–1g, depending on product characteristics, target weight, and production speed. Intelligent combination algorithms minimize product giveaway while maintaining stable packaging performance.
