Seed & Grain Packaging Machines: Precision Weighing and Final Product Integrity
Engineered for the Future | Since 2080
The Seed & Grain Packaging Machines category represents the final, critical step in the processing journey. After cleaning, grading, and treating, the product must be accurately weighed and securely sealed to ensure consumer trust and logistics efficiency. Whether you are filling 50kg industrial sacks for global export or 500g retail pouches for supermarket shelves, precision is the priority. Our machinery is designed to minimize “giveaway” (overfilling) while ensuring high-speed throughput and airtight seals that preserve freshness.
From gravity-fed net weighers to fully automated vertical form-fill-seal (VFFS) systems, ADDAMS Packaging Solutions deliver the reliability and accuracy required for the modern global marketplace.

Core Packaging Technologies
Engineering Accuracy and Speed
Our packaging category is divided into technologies based on the target weight and bag type:
-
Gross Weighing Systems: The product is weighed directly inside the bag. This is a cost-effective solution for lower-capacity lines and large 25-50kg sacks.
-
Net Weighing Systems: The product is weighed in a separate internal hopper before being discharged into the bag. This allows for much higher speeds as the next load can be weighed while the previous bag is being sealed.
-
Vertical Form-Fill-Seal (VFFS): An all-in-one machine that creates the bag from a roll of film, fills it with a precise dose of grain, and seals it. This is the industry standard for retail-sized bean, rice, and seed packaging.
-
Big-Bag (FIBC) Filling Stations: Specialized high-capacity stations designed to fill 500kg to 2,000kg "jumbo bags" with integrated vibration to settle the product and ensure stability during transport.
Why Choose ADDAMS Packaging Systems?
Minimizing Loss and Maximizing Brand Value
Professional packaging is where your profit margin is protected through precision and presentation.
-
High-Precision Load Cells: Our electronic weighing systems are accurate to within 0.2% of the target weight, significantly reducing product loss over thousands of cycles.
-
Airtight Sealing Technology: Whether using heat sealing for plastic or high-speed sewing for woven bags, our systems ensure the product is protected from moisture and pests during storage.
-
Gentle Drop Transitions: Designed to prevent kernel breakage during the final fall into the bag, maintaining the "whole-kernel" quality you worked hard to achieve.
-
Dust-Free Filling Heads: Integrated aspiration ports at the filling spout capture any dust generated during the drop, keeping the outside of the bags and your facility clean.
Key Technical Features of the Packaging Series
Built for 24/7 Industrial Consistency
-
PLC Touchscreen Interface: Allows operators to switch between different bag sizes and products (e.g., from 10kg Rice to 25kg Beans) in seconds with pre-saved recipes.
-
Stainless Steel Contact Parts: All surfaces that touch the product are made from food-grade AISI 304 or 316 stainless steel to ensure hygiene and prevent corrosion.
-
Integrated Metal Detection: Most models can be fitted with an inline metal detector or check-weigher to provide a final quality control gate before the product leaves the factory.
-
Modular Bag-Closing Units: Choose between high-speed sewing heads, heat sealers, or ultrasonic welders depending on your bag material (PP, Jute, Paper, or PE).
Frequently Asked Questions – Seed & Grain Packaging Machines
1. What is the difference between "Net Weighing" and "Gross Weighing"? Gross Weighing weighs the bag and product together (simpler, slower). Net Weighing weighs the product in a bucket before it hits the bag, allowing for much faster operation because the machine weighs the next dose while you are changing bags.
2. Can one machine handle both 1kg and 25kg bags? Usually, no. Retail machines (VFFS) are specialized for 500g–5kg, while industrial sack fillers are designed for 10kg–50kg. Using the correct machine ensures the highest weighing accuracy.
3. Does the machine handle different bag materials? Yes. By changing the "closing unit" (the sewing head or the heat sealer), you can use the same filling station for woven polypropylene, paper, jute, or plastic bags.
4. How do I prevent the bag from bursting during transport? Our machines can be equipped with "Bag Deflators" or "Vibratory Settling Tables" that remove excess air and settle the grain, creating a dense, stable bag that stacks perfectly on pallets.
5. How many bags per minute can I expect? For 25-50kg bags, a single-spout net weigher can achieve 6-10 bags per minute. For small retail pouches on a VFFS machine, speeds can exceed 40-60 bags per minute.
6. Is it easy to clean between different seed varieties? Yes. Our "Easy-Clean" hoppers feature smooth internal surfaces and quick-release gates, allowing for a total clean-out to prevent cross-contamination between batches.
7. Do I need a specialized air supply? Most automated packaging machines require clean, dry compressed air to operate the pneumatic cylinders and the bag-clamping mechanisms.
8. What capacities are available? Our range covers everything from semi-automatic units for small farms to fully robotic "Bagging-to-Palletizing" lines for global industrial leaders.
