ROTYPACK Doypack Filling Machine: Filling Technology and Material Adaptability

ROTYPACK Doypack filling machine serves as the core filling accessory for stand-up pouch packaging lines. It mainly performs quantitative filling for pre-made stand-up pouches and can work in coordination with various pouch packaging main machines. It is widely adopted for automated filling of sauces, liquids, powders, granules and pet food materials.

The machine provides differentiated filling technologies based on physical properties of materials to fit various production conditions. Closed screw filling structures are applied for powder materials to reduce dust scattering in workshops. Piston filling structures are used for high-viscosity sauces and pastes to deliver even output and lower residual material sticking on inner walls. Weighing filling structures are equipped for granular materials to maintain steady filling weight per pouch and limit measurement deviations.

Quick-disassembly filling heads are designed for simple dismounting and installation, facilitating regular cleaning and sanitization to avoid cross-contamination between different materials. Stepless adjustment of filling speed is available to meet low-speed precise filling and high-volume mass production. Compatible with stand-up pouches of various sizes, the machine fits standardized production systems of food processing factories.
