Automatic Granule Packaging Production Line | Z Type Elevator, 14 Head Multihead Weigher & 8 Station Premade Pouch Packing Machine
Share to:
This automatic granule packaging production line is designed for high-speed and accurate weighing and pouch packing of granular products. The complete system mainly consists of a Z type bucket elevator, working platform, 14-head multihead weigher, and 8-station premade pouch packing machine with ribbon date coding function. The integrated solution provides automatic feeding, weighing, bag opening, filling, sealing, and finished product output. It is suitable for granules, snacks, nuts, frozen food, and irregular materials requiring stable weighing accuracy and efficient automated packaging performance.
Machine Overview and Functional Description
The automatic granule packaging line is an integrated packaging solution specially developed for quantitative weighing and premade pouch packaging of granular, irregular, and fragile materials. The system combines automatic material conveying, intelligent weighing, bag feeding, pouch opening, filling, coding, sealing, and product discharge into one fully automated process.
The Z type bucket elevator continuously conveys materials to the multihead weigher through food-grade buckets while minimizing material damage during transportation. The supporting working platform provides stable equipment installation and convenient maintenance access.
The 14-head multihead weigher adopts intelligent combination weighing technology to achieve high-speed and high-precision weighing performance. The integrated collection hopper concentrates materials into a single discharge point for faster filling speeds. The system supports both weight-based and counting-based dosing methods depending on product characteristics.
The weighing system features automatic vibration amplitude adjustment, photoelectric detection, and recipe memory functions, allowing operators to quickly switch between products while maintaining stable weighing accuracy. Anti-collision material control design helps reduce product breakage, making the machine suitable for fragile snacks and irregular granules.
The 8-station premade pouch packing machine adopts a fully automatic rotary operating structure. The machine automatically performs pouch feeding, date coding, zipper opening, bag opening, filling, vacuuming, sealing, and finished product discharge. If the pouch is not opened correctly, the machine will not fill or seal the bag, greatly reducing material waste and improving packaging reliability.
The equipment frame and product contact parts are manufactured from SUS304 stainless steel to meet food-grade hygiene requirements. The entire production line is suitable for continuous automated packaging operations with stable performance and high production efficiency

Structural Design and Working Principle
1. 8 Station Premade Pouch Packing Machine
The rotary 8-station pouch packing machine automatically completes bag feeding, zipper opening, date coding, filling, sealing, and finished pouch discharge. Intelligent pouch detection prevents filling and sealing when the pouch is not properly opened, reducing packaging waste and improving production reliability.
2. Z Type Bucket Elevator
The Z type elevator adopts food-grade bucket conveying technology for continuous automatic material feeding. The gentle lifting structure minimizes product breakage and is especially suitable for fragile snacks, nuts, frozen food, and irregular granules.
3. 14 Head Multihead Weigher
The 14-head combination weigher utilizes intelligent combination calculation for high-speed and high-precision weighing performance. Automatic vibration adjustment and anti-collision feeding design improve weighing stability while protecting delicate products from damage during operation.
4. Stainless Steel Working Platform
The integrated working platform provides stable structural support for the weighing and packaging system. The anti-slip stair structure and safety guardrails improve operator safety while allowing convenient maintenance and daily equipment inspection.
FAQs
Q1: What products can this packaging line handle?
The machine is suitable for snacks, nuts, frozen food, candy, pet food, plastic granules, hardware parts, and other granule or irregular materials.
Q2: Is the machine suitable for fragile products?
Yes. The multihead weigher adopts anti-collision feeding technology and gentle conveying design to reduce product breakage during weighing and filling.
Q3: Can the machine pack zipper pouches?
Yes. The 8-station premade pouch machine supports zipper pouches, stand-up pouches, flat pouches, and other premade bag types.
Q4: What happens if the pouch is not opened correctly?
The machine automatically detects pouch opening status. If the pouch is not properly opened, the system will not fill or seal the bag, preventing material waste.
Q5: Can different weighing methods be integrated?
Yes. The packaging machine can be connected with multihead weighers, counting machines, volumetric cup systems, liquid fillers, powder dosing systems, and other feeding solutions according to product requirements.
