Granule Packaging Machine: LEESOLU Customized Weighing & Packaging Solutions for High-Volume Production
As consumer demand across food, household chemicals, and hardware industries continues to rise, granule products — including nuts and roasted seeds, candies and puffed snacks, pet food, detergent granules, and small hardware parts — are seeing steady sales growth. Granule manufacturers face peak seasons with concentrated batch orders, and the need for large-scale, standardized packaging has never been greater.
The granule market demands diverse packaging formats. The same product often requires different packaging processes depending on customer positioning and end-market needs: nuts and candies may be packaged in bottles for some clients and in pouches for others; seasoning granules and instant drink mixes commonly require a sachet-in-pouch secondary packaging format (small sachets packed into a larger outer pouch). LEESOLU's customized granule packaging machine systems adapt to bottle filling, pouch packaging, and sachet-in-pouch secondary packaging scenarios. Tailored to each client's unique production requirements, our solutions drive standardization and automation for maximum efficiency.
Core Challenges in Granule Mass Production
The granule industry's diverse customization needs become even more challenging during peak full-capacity production:
1. High-Precision Weighing Is Hard to Maintain
Granule products have strict metering standards. Lightweight puffed granules and small hardware parts are easily affected by airflow on the production floor. Conventional weighing equipment lacks protective design, resulting in noticeable weighing deviations, underweight finished products, and material waste — failing to meet quality control requirements.
2. Irregular Granules Cause Jams and Production Interruptions
Strip-shaped, flake-shaped, and irregular granule materials pose special handling challenges. Conventional feeders deliver material unevenly, leading to jams, buildup, and blockages that require manual cleaning. This disrupts continuous automated production and reduces overall output efficiency.
3. Sachet-in-Pouch Secondary Packaging Is Complex and Labor-Intensive
Many customers specify a secondary packaging format — small sachets packed into a larger pouch — for their granule products. This process involves multiple steps: sachet filling, placement into outer pouches, and weight rechecking. Traditional production lines keep these steps disconnected, relying on manual transfer and sorting. This not only drives up labor costs but also makes standardized batch packaging difficult to achieve.
Customized Granule Weighing and Packaging Solutions
Addressing the granule industry's diverse customization needs, LEESOLU designs dedicated, complete production systems for three mainstream packaging processes: bottle filling, pouch packaging, and sachet-in-pouch secondary packaging. Each system is matched to specific order requirements, allowing manufacturers to flexibly select configurations based on their core product lines.
Granule Weighing and Bottle Filling System
This granule packaging machine is designed for weighing various granular and strip-block materials, including sunflower seeds, almonds, pistachios, pine nuts, candies, puffed food, beans, frozen food, pet food, snack foods, small hardware, and household chemical granules. For production scenarios requiring high precision, the system is equipped with a windproof curtain to effectively eliminate weighing deviations caused by workshop airflow.
Key components: multihead weigher, bottle filling unit, windproof enclosure.
Granule Weighing and Pouch Packaging System
This system features a modular, interconnected design. A vibration feeder delivers material evenly to eliminate jams and blockages, a bucket elevator transports material smoothly, and a 16-head three-layer combination weigher provides precise proportioning and quantitative weighing. Paired with a vertical packaging machine, it completes automated bag forming, filling, and sealing in one continuous flow — delivering intelligent, high-efficiency production for all types of granule pouch packaging needs.
This combined granule packaging machine system supports production requirements for independent small sachets packed into larger outer pouches, and is widely compatible with snack foods, household chemicals, hardware, and other industries. The equipment sequentially completes material feeding, high-precision intelligent quantitative weighing, and automatic pre-made pouch sealing. Finished products pass through a checkweigher for weight inspection and quality sorting. The entire process runs as integrated, automated operation, enabling standardized mass production of sachet-in-pouch secondary packaging.
Key Technical Features of LEESOLU Granule Packaging Machines
1. Customized Process Adaptation Across All Scenarios
Each system is purpose-built for bottle filling, pouch packaging, or sachet-in-pouch secondary packaging — precisely matching each customer's differentiated order requirements.
2. Accurate, Stable Weighing for Consistent Quality
To solve the challenge of weighing lightweight granules, our multihead weighers feature windproof structures that effectively shield against workshop airflow interference. This stabilizes metering accuracy, reduces material errors and waste in batch production, meets granule manufacturing compliance standards, and ensures consistent finished-product quality.
3. Stable Continuous Operation for Higher Output
Our dedicated granule packaging systems use modular design and smooth material handling structures to solve jams and blockages caused by irregular granules. Stable equipment operation significantly reduces manual intervention, making the systems well-suited for high-volume, multi-order customized production during peak seasons.
4. Full-Process Automation for Lower Costs and Higher Yield
All three dedicated systems achieve full-process automation for their respective packaging processes, replacing labor-intensive manual transfer, sorting, and rechecking. This effectively reduces labor costs, unifies product packaging standards, improves finished-product pass rates, and helps manufacturers efficiently deliver customized orders.
Target Industries and Applications
Food Processing Manufacturers

Frequently Asked Questions
Q1: Our product range is narrow — do we need to purchase a complete set of equipment?
No. Equipment can be selected and customized on demand. Manufacturers can precisely select based on mainstream customer customization needs: choose the granule weighing and bottle filling system for bottle-dominant orders, the granule weighing and pouch packaging system for pouch-dominant orders, and the dedicated secondary packaging system for sachet-in-pouch orders. This precisely matches production needs while controlling equipment investment costs.
Q2: Is changeover and debugging convenient? Can the equipment handle multiple product specifications?
Yes. The systems are compatible with automated packaging of a wide range of granule materials. Pouch packaging lines cover nuts, candies, puffed snacks, pet food, seasonings, and more; bottle filling lines handle various granular and block materials; sachet-in-pouch lines perform secondary packaging for all types of granule products. The modular structure enables quick production line reconfiguration, fully meeting multi-product mass production needs and significantly improving line flexibility.
Q3: Can the equipment integrate with our existing production line?
All systems reserve standardized docking interfaces and can flexibly connect with downstream equipment such as labeling machines, case packers, and inspection systems — effectively reducing line upgrade costs and adapting to various customized production line layouts.
