ROTYPACK Doypack Filling Machine: Structural Features and Filling Process Analysis of Premade Pouch Filling Machine

The ROTYPACK doypack filling machine is a special supporting filling device for stand-up pouch packaging lines. It can cooperate with various bag-feeding packaging hosts for quantitative filling of pre-made pouches, widely used in automatic filling production of sauce, liquid, powder, granules and pet food. The filling structure is optimized according to the physical properties of different materials to adapt to diverse production conditions.

Closed screw filling structure is adopted for powdery materials to reduce dust diffusion and keep the workshop clean. Piston filling structure suits high-viscosity pastes and sauces to ensure uniform discharging and reduce material residue and dripping. Granular materials adopt weighing filling structure to stabilize filling data, reduce measurement fluctuation and guarantee consistent packaging of batch products.

The filling head adopts a quick-release design for tool-free disassembly and assembly, facilitating daily cleaning, disinfection and maintenance to avoid cross-residue of different materials. The stepless adjustable filling speed adapts to small-batch refined production and high-speed mass production, fitting filling operations of various specifications of pre-made stand-up pouches.
