Doypack Filling Machine: Filling Principle and Advantages of Precision Filling for Stand-up Pouches

ROTYPACK Doypack Filling Machine serves as the core filling equipment for stand-up pouch packaging lines. It focuses on quantitative filling of premade stand-up pouches and can be matched with various pouch-given packaging main machines. It is widely used for filling production of seasoning sauces, food powders, granular ingredients and pet food materials.

     
Multiple filling processes are adopted according to material characteristics to fit different food materials. The enclosed screw filling structure is applied for fine powder materials to reduce dust emission and maintain a tidy workshop environment. The piston filling structure is used for high-viscosity sauces and pastes to deliver consistent discharging and lower material adhesion on chamber walls. The weighing filling structure is equipped for granular materials to maintain consistent weight of each pouch and control metering deviation.

The filling components adopt a quick-disassembly design for easy disassembly and assembly, enabling rapid cleaning and sanitization to avoid cross contamination from residual materials and meet hygienic standards for food production. The filling speed supports stepless adjustment, suitable for low-speed precision filling and high-speed mass production, and meets filling demands for stand-up pouches of various specifications.
