Structure and Principle of Doypack Pre-made Pouch Packing Machine and Its Application in Food Industry

Doypack pre-made pouch packing machine is a horizontal automatic packaging equipment widely used in the food processing industry. It performs automatic packaging processes with pre-made stand-up pouches without roll film for pouch making. The machine automatically completes the whole workflow including pouch picking, pouch opening, material filling, heat sealing and finished product discharging, suitable for continuous mass production in food factories.

                                                           
The machine adopts a horizontal multi-station rotary structure. Each station works separately and runs simultaneously to maintain steady production rhythm. It can handle various food materials such as granules, powders, pastes and liquids. Quantitative filling is realized by matching different metering modules. It supports common pouch styles including standard stand-up pouches, zipper stand-up pouches and spout stand-up pouches. Product specifications can be adjusted by replacing simple tooling, supporting shared production lines for multiple food varieties.

Material contact parts of the machine are made of food-grade stainless steel. The detachable structure facilitates routine cleaning and disinfection and meets hygiene requirements for food production. The whole machine is equipped with an easy-to-operate electric control system with clear parameter adjustment. It can operate as a standalone unit or connect with upstream feeding, mixing and conveying equipment to form a full automatic production line, applicable to production scenarios for seasonings, snack foods, pet food and other products.
