1.The Challenge: A customer packing a six-ingredient mixed nuts product needed a complete automated packaging process to improve filling accuracy, protect product freshness, and keep the whole line running continuously.
Below is the can picture from customer.
l Precise multi-ingredient weighing – A product containing several kinds of nuts requires accurate, repeatable weight control for each pack to avoid product giveaway.
l Freshness protection – Nuts are sensitive to oxygen and moisture, so controlled handling and a protective atmosphere help maintain quality and shelf life.
l Continuous production flow – Unscrambling, sterilization, filling, sealing, labeling, and collection need to work together smoothly to avoid bottlenecks.
In addition, granule filling, multi-head weighing, vacuum nitrogen sealing, labeling, and collection need to work together smoothly to avoid production bottlenecks.
2. The Solution: We supplied a fully integrated mixed nuts filling line that connects container handling, sterilization, granule filling, multi-head weighing, vacuum nitrogen sealing, labeling, and collection into one continuous process. Key features include:
（Please contact us for high-resolution images.）
l Automatic bottle unscrambling & UV sterilization – Automatically arranges empty containers and runs them through a UV sterilization channel before filling to support a cleaner packaging process.
l Linear granule filling machine & six-head 999g multi-head weigher – Fills granule products and weighs each pack accurately to the required 999g dose with stable, repeatable performance.
l Chain bucket elevator – Lifts and feeds the nuts smoothly into the filling stage, keeping product flow continuous and gentle on the product.
l Vacuum & nitrogen-flushing sealing machine – Creates a controlled atmosphere inside the container, helping protect freshness and extend shelf life.
l Round bottle labeling & turning mechanism – Labels round containers accurately and re-orients them for the next process stage.
The complete line is designed for continuous operation, reducing manual transfers between processes and creating a more organized production flow. The exact output and performance depend on the final product, container, and process specifications.
Key Customer Benefits
l Higher efficiency – Multiple packaging processes are connected into one line, reducing manual handling and improving production continuity.
l Accurate, consistent dosing – The six-head multi-head weigher and granule filling stage maintain controlled filling performance and reduce product giveaway.
l Better freshness protection – Vacuum and nitrogen flushing before sealing create a controlled atmosphere that helps protect the quality and shelf life of the nuts.
l Cleaner packaging process – UV sterilization at the front end supports a more hygienic handling flow.
l Streamlined finished-product handling – Labeling, turning, and collection are integrated to keep the line moving.
3. Customer Review
We are very satisfied with the mixed nuts filling line supplied by LANDPACK. The complete line has significantly streamlined our production process, from bottle unscrambling and UV sterilization to granule filling, multi-head weighing, vacuum nitrogen sealing, labeling, and final collection.
The six-head multi-head weigher provides accurate and consistent dosing, which helps us keep pack weights stable and reduce product giveaway. The vacuum and nitrogen flushing system also gives us greater confidence in protecting the freshness and shelf life of our nuts.
The whole line is well integrated and easy to operate. It has reduced manual work, improved production efficiency, and made our packaging process much more consistent. LANDPACK’s technical support throughout the project was also professional and responsive. We are pleased with the overall solution and the performance of the equipment.
