Multi-head Combination Weigher Packaging Machine: Address High-precision Flexible Packaging Challenges for Granular Materials

Solid materials including snacks, grains, freeze-dried food and pet pellets are mainstream processing products in European and American markets, and multi head weigher packaging machines serve as core equipment on production lines. Conventional weighing and packaging equipment available on the market mostly adopts a simple single-group weighing structure, which frequently causes issues such as material jamming of tiny materials, unstable weighing results and cross-contamination of mixed materials. The disassembly and cleaning procedures are complicated when switching between materials of various specifications, failing to comply with EU food hygiene standards and the flexible production demands for multiple SKUs.

Shanghai Rutian Intelligent develops integrated multi-head combination weigher packaging units with full-servo coordinated control covering weighing, blanking and sealing procedures to resolve prominent pain points in mass production of granular materials.

The equipment is equipped with high-precision multi-head digital combination weighing modules with independent sensing and weighing for each channel, keeping dynamic weighing error within ±0.1g. It enables accurate proportioning for irregular lumpy materials, fragile freeze-dried products and smooth granular materials. Fitted with buffer and shock-absorbing blanking chutes, the system prevents collision and breakage during material falling to maintain intact appearance of finished products. All parts in direct contact with food are made of detachable 316L stainless steel without concealed gaps. A single operator can complete quick disassembly and cleaning without tools, avoiding flavor cross-contamination between different materials and complying with management standards for aseptic food workshops.

The complete unit realizes integrated linkage of weighing, bag feeding, filling and sealing. Full-servo drive is applied to replace traditional cylinder mechanical linkage to greatly improve synchronization among each working procedure. An intelligent anti-jamming sensing device is built in to trigger automatic vibration for blockage removal when material bridging and clogging occur, eliminating manual cleaning shutdown and lowering production line downtime. The device supports one-click parameter storage; preset programs can be directly called to switch between different weight specifications and material types, cutting commissioning time by 70% and matching the business mode of frequent new product launches for brands.

A multi-language touch control system is installed on the machine body to automatically record weighing data and yield rate of each batch. Production logs can be exported and filed to meet traceability supervision requirements of overseas food manufacturers. The unit supports two packaging forms including prefabricated pouch packaging and roll film forming, compatible with various pouch styles such as three-side sealed bags and stand-up pouches. In addition, it can connect with auxiliary equipment including material sorting machines, metal detectors and case packers to build a fully automatic production line. The company provides standardized English operation manuals and remote commissioning services, delivering integrated weighing and packaging solutions featuring high precision and low material loss for overseas manufacturers processing granular materials.
