Doypack Packaging Machine: Analysis on Structure of Premade Pouch Packaging Equipment and Applications in Food Industry

ROTYPACK Doypack Packaging Machine is an automatic packaging equipment widely used in the food processing industry. The machine adopts a horizontal rotary structure design and completes the whole packaging process with finished premade doypacks. Without the configuration for film forming, it realizes automatic production through premade pouch feeding, opening, filling, sealing and discharging. It simplifies workshop technological processes and fits standardized mass production of food products.

       
The machine operates with multiple working stations running simultaneously. Each process has clear division of work and coordinated operation. It handles various food materials including granules, powders, liquids and pastes. Quantitative filling can be realized by matching different metering modules to meet production demands of seasonings, snack foods, grain materials, pet food and other categories. The machine supports the production of various common premade pouch types, including flat-bottom doypacks, zipper pouches and spout pouches. Parameter adjustment and simple tooling replacement are required for product changeover.

Parts in contact with materials are made of food-grade stainless steel with smooth surfaces to reduce material accumulation. The detachable structure facilitates daily cleaning and maintenance, complying with requirements for hygienic food production. The machine features neatly arranged electric control system with simple operation logic. It can run independently or connect to automatic production lines for coordinated operation, suitable for food processing workshops of various scales.
