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

The Doypack pre-made pouch packing machine is a mainstream horizontal automatic packaging equipment in the food processing industry. It completes the whole packaging process by adopting pre-made stand-up pouches without roll film for bag making, which effectively streamlines production procedures and material inventory management. Equipped with a proven multi-station rotary structure, the machine realizes fully automated operations including pouch feeding, pouch opening, material filling, heat sealing and finished product discharging, suitable for standardized continuous factory production.

                        
The machine adapts to common materials in the food industry. Corresponding metering modules are available for granules, powders, sauces and liquid materials to achieve quantitative filling. It supports multiple standard pre-made pouch styles such as flat-bottom stand-up pouches, zipper pouches and spout pouches. Specifications can be switched by replacing simple tooling parts to meet co-production requirements of various food products and pet food.

Material contact parts of the machine are made of food-grade stainless steel. The detachable structure facilitates routine cleaning and disinfection and complies with clean production standards for food workshops. The complete machine features neatly arranged electric control system with intuitive and convenient parameter adjustment. It can operate independently or connect with feeding, mixing and conveying equipment to form an automatic packaging production line, fitting production scenarios of different capacity levels.
