Dosing‑filling Structure and Sanitary‑maintenance Design

The ROTYPACK doypack filling machine is a dedicated dosing filler for pre‑made stand‑up pouches. It works in coordination with various bag‑feeding packaging hosts to realize integrated filling, sealing and conveying. It serves automatic filling for sauces, broths, edible oil, powder ingredients, granular food and puffed food in condiment plants, food factories and pet‑food workshops.

Different filling structures are deployed for material physical properties. Fully enclosed screw filling suppresses powder escape for clean workshop environment. Piston filling heads deliver steady flow for high‑viscosity sauces and pastes to lessen wall adhesion, dripping and residue and lower material loss. Dynamic weighing filling units control single‑shot weight and stabilize batch accuracy for granular products.

Core filling assemblies adopt quick‑release construction. Operators can complete disassembly, washing, disinfection and reset without special tools. It simplifies routine maintenance and avoids cross‑contamination risks during product change‑over to satisfy clean‑production‑workshop requirements.

Stepless filling‑speed adjustment supports small‑batch custom runs as well as high‑volume mass‑production lines, compatible with standard‑size pre‑made stand‑up pouches. Rich electric‑control settings fine‑tune filling parameters for material traits, pouch dimensions and capacity targets, balancing smooth operation and equipment durability.
