New Integrated Granular Product Packaging Solution Breaks Technical Barriers in Conventional Packaging Industry

Traditional equipment applied in global granular product packaging has long been troubled by common drawbacks including obvious metering errors, complicated model switching procedures, restricted production capacity and heavy reliance on manual labor. Such equipment can hardly meet the strict requirements on food compliance, flexible production capacity and cost control raised by European and American markets. Relying on self-developed full-servo core framework, Shanghai Rotypack Intelligent Equipment launches an all-in-one granular product packaging system, restructuring the production logic of granular packaging with standardized technological breakthroughs. The company supplies overseas processing enterprises with automated solutions that match the specifications of imported equipment while delivering better cost performance.

Equipped with a closed-loop dynamic weighing and metering module, the whole unit adopts graded feeding algorithms of rough feeding and fine feeding. It automatically compensates for material drop in real time for materials of different densities such as nuts, grains, feed and chemical particles. During continuous mass production, the metering error of each bag stays within ±0.3%, which outperforms the over ±1% deviation of conventional volumetric equipment widely used in the industry. It reduces raw material waste and helps enterprises pass weight sampling inspections required by European and American supermarkets. The complete machine is driven by a full set of servo systems, with a synchronization accuracy of ±0.1mm for multi-station operations. Processes including bag feeding, bag opening, filling, sealing and coding run in uninterrupted linkage. The pre-made bag model can reach a stable production speed ranging from 25 to 250 bags per minute. A single unit can replace 3 to 5 sets of old single-row packaging lines, cutting workshop labor demand by over 70%.

 For specification modification, many industrial machines need component disassembly and replacement. This product line is equipped with a touch screen intelligent central control system that stores hundreds of parameter sets for diverse raw materials and pouch formats. Operators can switch operating programs with a single click to process zipper pouches, stand-up pouches, eight-seal pouches and custom shaped filling pouches, with product switching finished within 3 minutes. This configuration matches the multi-SKU, small-batch and quick-order production mode commonly used by European and American brands. All material contact components are constructed from food grade 316 stainless steel. Built-in sealed dust prevention and anti-static structures allow easy disassembly, cleaning and sanitization, conforming to EFSA food hygiene requirements set by the European Union. The modular machine framework reduces the quantity of wearing parts by 40%, lowering total annual maintenance costs by 25% and delivering stable investment benefits during long-term running periods.

As a high-tech enterprise participating in drafting two industrial standards for packaging machinery, Rotypack Intelligent narrows the technological gap occupied by overseas manufacturers in high-end servo packaging equipment. Its equipment matches the performance level of mainstream imported machines from Europe and America, alongside global on-site after-sales service and localized remote technical support. This granular packaging solution has been put into mass use in multiple export production lines covering dairy products, pet food, health supplements and agricultural particles. It streamlines production workflows and lowers overall manufacturing costs for partners, creating differentiated production strengths amid global supply chain competition. The company will keep upgrading intelligent IoT monitoring and predictive maintenance functions, and deliver steady technical support for intelligent transformation within the global granular packaging sector via independent core technologies.
