Operating Principle of Doypack Pre-made Pouch Packing Machine and Its Application in Food Packaging Production

The Rotypack Doypack pre-made pouch packing machine is an automatic horizontal packaging equipment widely used in the food processing industry. It performs packaging operations with finished pre-made pouches without the roll film bag-making process, simplifying the management of production consumables. The machine integrates full automatic procedures including pouch feeding, pouch opening, material filling, heat sealing and finished product discharging. It features a mature overall operation flow for continuous mass production in food factories.

           
The Rotypack machine adopts a multi-station rotary circulating structure with synchronized operation of each process to maintain stable production rhythm. It handles various food materials such as powders, granules, liquids and pastes. Different metering modules including screw, piston and weighing types can be configured to meet requirements of quantitative filling for diverse materials. The equipment supports multiple pouch styles including standard doypacks, zipper doypacks and spout doypacks. Specifications can be switched by replacing simple tooling parts to facilitate co-production of various food and pet food products.

Material contact components of the Rotypack machine are made of food-grade stainless steel. The detachable structure supports convenient daily cleaning and sanitization, complying with hygiene standards for food workshops. The electric control system features simple operation and intuitive parameter adjustment. The machine can run independently or connect with feeding, conveying and coding equipment to form a complete automatic production line, suitable for food production scenarios of various scales.
