Doypack Filling Machine – Quantitative Filling Structure and Cleaning Maintenance Design

ROTYPACK Doypack Filling Machine is designed for quantitative filling of pre-made stand-up pouches. It can work with various pouch packaging hosts for automatic filling of sauces, soups, oils, powders, granules and puffed materials. The machine is commonly installed on automatic production lines in condiment factories, snack food plants and pet food factories.

Different filling structures are adopted based on physical properties of materials. Closed screw filling structure for powder materials to reduce dust emission in workshops. Piston filling heads for thick sauces and pastes to improve discharging uniformity and reduce material adhesion and dripping. Weighing filling assemblies for granular products to keep consistent filling weight per pouch.

The whole filling head features quick-release design. Disassembly and assembly can be finished without complicated tools, facilitating daily cleaning, sanitization and maintenance, and lowering cross-contamination risks between different materials. Filling speed supports stepless adjustment to fit small-batch refined production or high-volume mass production lines.

The machine can operate independently or connect with doypack packaging hosts to build integrated filling and packaging lines. The electronic control system supports wide parameter adjustment range to set filling volume, speed and coordination rhythm based on actual production needs. The overall structure balances production efficiency and cleaning maintenance.
