Metering Principle of Doypack Pre-made Pouch Filling Machine and Precise Filling Technology for Food Materials

The Doypack pre-made pouch filling machine serves as the core metering equipment on stand-up pouch packaging lines. It focuses on quantitative filling of pre-made pouches and can work with various pouch feeding packaging main machines. It is widely used for filling production of seasoning sauces, food powders, snack granules, pet food and other materials.

                           
The machine is equipped with corresponding filling structures according to properties of different food materials. Closed screw filling structures are adopted for powder materials to reduce dust dispersion. Piston filling structures are used for high-viscosity sauces and pastes to maintain even and stable discharging. Granular materials are matched with weighing filling structures to keep weight deviation of each pouch within controllable range. Multiple metering modes can be selected freely based on product requirements.

The filling head of the machine adopts a quick-release design for convenient assembly and disassembly, facilitating daily cleaning and maintenance and lowering cross contamination caused by residual materials. The filling speed supports stepless speed regulation. It can adapt to low-speed precise filling scenarios as well as high-volume high-speed production conditions, meeting filling requirements of stand-up pouches in different sizes.
