Automatic Paste Filling Machine | Pneumatic Piston Sauce Packing Machine with Heating & Mixing Hopper
Share to:
This automatic paste filling machine is specifically designed for viscous and semi-viscous products. Equipped with a pneumatic piston dosing system, it ensures accurate filling for thick materials. The machine features a heating and mixing hopper to prevent solidification and improve flowability. It is widely used for sauces, creams, and chemical pastes requiring stable and continuous packaging.
Machine Overview and Functional Description
This paste packaging machine integrates mechanical, pneumatic, and electronic systems into a fully automated solution for viscous material packaging. The entire machine is constructed with high-quality stainless steel, ensuring durability, hygiene, and suitability for food, pharmaceutical, and chemical applications.
The machine adopts an advanced microcomputer control system combined with a user-friendly 5-inch LCD interface. The intelligent PLC system ensures synchronized operation, accurate bag length control, positioning, and speed regulation. The photoelectric tracking system guarantees precise sealing and cutting alignment for each bag.
Equipped with a pneumatic piston filling system, the machine provides high-precision volumetric dosing, especially suitable for thick, sticky, or non-free-flowing materials. The filling volume can be easily adjusted, and the system ensures consistent output without dripping or material waste.
The heating and mixing hopper is specially designed for materials that tend to solidify or separate. The integrated agitator ensures uniform consistency, while the heating function maintains optimal viscosity during operation.
Optional configurations include date coding (ink ribbon or embossing), tear notch, chain bag system, nitrogen flushing, and special sealing shapes such as round corner cutting.
This machine completes bag forming, filling, sealing, cutting, and output automatically, offering a reliable and efficient packaging solution.
