High-Efficiency Automated Granule Packaging Solution
The Premade Pouch Granule Packing Machine is a high-performance automated device designed for premade pouch packaging of various granular materials. It can automatically complete the entire process of bag picking, opening, metering and filling, sealing, and finished product output. This equipment is suitable for various bag types, including stand-up pouches, flat bags, hanging pouches, zipper bags, and irregularly shaped bags, and can be widely used in the food, daily chemical, pharmaceutical, agrochemical, and chemical industries. Its compact horizontal structure saves production workshop space and can be easily integrated with upstream conveying equipment and downstream labeling and packing equipment to build a high-efficiency continuous production line, significantly improving capacity and production efficiency.
Precise Metering and Reliable Sealing Ensure Product Quality
This equipment is equipped with a high-precision weighing system and a two-stage filling mechanism, which can quickly complete coarse and fine filling, ensuring that the weight of each bag of granules is uniform and consistent, avoiding material waste or customer complaints caused by overfilling or underfilling. The sealing system uses temperature-controlled heat sealing or pressure strip sealing technology, resulting in a strong, aesthetically pleasing, and flat seal, effectively preventing granule leakage and packaging damage. Independent and coordinated filling and sealing modules, controlled by a PLC program, enable rapid switching between multiple specifications and materials, ensuring continuous production stability and meeting stringent food and pharmaceutical production standards.
Multifunctional Adaptability and Hygienic Safety Design
The Premade Pouch Granule Packing Machine is compatible with various granular materials, including nuts, sugars, grains, seeds, feed pellets, and chemical or pharmaceutical pellets, adapting to different particle shapes and flow characteristics. The equipment features a closed filling chamber and a high-efficiency dust removal system, effectively suppressing dust diffusion, maintaining a clean production environment, and complying with FDA and EU food contact safety standards. All parts in contact with materials are made of food-grade stainless steel or hygienic materials, facilitating disassembly, cleaning, and routine maintenance, ensuring a safe and hygienic production process. Automated operation reduces reliance on manual labor, minimizing product loss and production costs due to errors, helping companies achieve cost reduction, efficiency improvement, and high-quality packaging goals.
High Applicability and Economy
This equipment supports multiple specifications and types of pre-made bags and can be equipped with nitrogen purging, infrared detection, and error-proofing control systems according to customer needs to extend the shelf life of easily oxidized granular materials and improve packaging safety. Through intelligent control and modular design, the machine is easy to operate, has low training costs, is convenient to maintain, and operates stably and reliably, making it suitable for modern production lines that pursue high capacity, high precision, and low loss. The Premade Pouch Granule Packing Machine, with its high efficiency, accurate metering, stable sealing, and multi-functional adaptability, provides enterprises with an economical, efficient, and sustainable granule packaging solution, making it an indispensable core piece of equipment in modern granule packaging production.
Premade Pouch Granule Packing Machine Solutions
Built for free-flowing and irregular granules such as nuts, snacks, rice, seeds, sugar, pet food, and detergents, this system runs premade bags including doypack, zipper, flat, and quad-seal styles. It is available on rotary carousels (8–10 stations) or a horizontal layout, integrates advanced weighing, and delivers clean, consistent seals. All machines are engineered in-house. Since 1999, they have been supplied with GMP and CE conformity.
What Makes This System Different
Custom configuration: Infeed and dosing matched to product flowability and fragility.
Accurate, repeatable results: Multihead/linear weighing and independent sealing zones improve consistency.
Scalable integration: Elevators, printers, labelers, checkweighers, case packing, and palletizing under one control layer.
Hygienic construction: Stainless steel frames (SS304/SS316) with smooth, accessible surfaces for cleaning.
How It Works
Station sequence: Pouch magazine and pick, date coding, opening and shaping, dust removal, filling, sealing, and discharge.
Platform choice: Rotary excels at format flexibility and sealing stability. The horizontal layout favors larger pouches and heavier fills.
Control and safety: Servo-driven motions ensure precise timing. Sensors verify pouch presence and opening to prevent spills.
Dosing Options for Granules
Multihead weigher: Best for mixed or fragile items; high speed and accuracy.
Linear weigher: Balanced accuracy and cost for uniform pieces.
Volumetric cup filler: Economical solution for free-flowing rice and sugar.
Gentle transfer paths and short drop heights protect product integrity.
Process Control and QA
In-line inspection: Checkweighers, metal detectors, and reject devices.
Atmosphere control: Optional nitrogen flushing for doypacks to support shelf life.
Seal assurance: Temperature and pressure control maintain seal quality across different laminates.
Key Specifications and Models
Performance: Up to 60 pouches per minute, depending on product and size.
Pouch sizes: Approx. 80–260 mm wide and 120–350 mm high; supports gussets and zippers.
Fill range: 5 g to 5 kg with the appropriate dosing system.
Utilities: 220/380 V, 50/60 Hz; compressed air around 0.6 MPa; efficient drives to reduce energy use.
Materials: PET/PE, PA/PE, paper/foil/PE, and recyclable mono-PE with adaptive sealing parameters.
Variants: Rotary 8- or 10-station for general granules; horizontal platform for large formats and heavy fills; optional washdown builds for high-hygiene areas.
Applications
Food and snacks: Nuts, rice, coffee beans, seeds, candies, and chips.
Pet food and feed: Kibble and treats with robust zipper closures.
Chemicals and agriculture: Detergents, fertilizers, desiccants, and water-treatment media with dust control.
Hardware and DIY: Screws, fasteners, and small parts by counting or weighing; add tear notches and hang holes.
Installation and Lifecycle Support
Factory testing: Acceptance trials with your products to verify dosing accuracy and interfaces.
Commissioning and training: On-site setup, recipe optimization, and operator instruction.
After-sales: Spare parts kits, remote assistance, and preventive maintenance plans to support uptime.

FAQs
Q: Which pouch types are supported?
A: Doypack, zipper, flat, and quad-seal, with options for hang holes, tear notches, and rounded corners.
Q: What products and granule sizes can it handle?
A: A wide range from nuts and rice to seeds, pet food, detergents, and small hardware, matched to flowability and fragility.
Q: How do I choose between a multihead weigher and a volumetric cup?
A: Use multihead for mixed or fragile items; volumetric cups for uniform, free-flowing products. Linear weighers balance both.
Q: What is a typical changeover time?
A: With recipe management and tool-less parts, changeovers are usually completed in minutes.
Category Notes for Granules
For granule applications, prioritize weighing accuracy, gentle handling, and dust mitigation. Zipper doypacks and gusseted formats suit heavy fills and maintain shelf presence.
