Paste Packing Machine——Industrial Viscous Filling & Packaging System
Paste products cover a wide range of industrial and food applications, from tomato paste and peanut butter to adhesives, gels, and chemical creams. What they share in common is high viscosity, uneven flow behavior, and a tendency to stick to internal surfaces during processing. These characteristics make paste filling significantly more complex than standard liquid packaging.
The Paste Packing Machine developed by MIC Machinery is designed to handle thick, semi-solid materials with stable dosing accuracy and controlled discharge. It is widely used in food processing plants, cosmetic factories, chemical production facilities, and industrial adhesive packaging lines.
Unlike conventional liquid fillers, paste systems must manage strong resistance during flow, prevent clogging, and maintain consistent cut-off without dripping or stringing.

Working Process
The paste packing process begins with material preparation in a mixing or holding tank. Depending on the product, the paste may be heated or continuously agitated to maintain stable viscosity. This step is critical for materials such as peanut butter, tomato paste, or industrial adhesives, where uneven texture can affect flow consistency.
Once stabilized, the paste is transferred into a buffer hopper connected to the filling system. The hopper ensures a steady supply of material while minimizing air entrapment, which could lead to inconsistent dosing.
Empty containers are automatically transported to the filling station and positioned under the nozzles using sensor-based alignment systems. Once in place, the piston or servo system draws a measured volume of paste from the hopper and discharges it into each container with controlled pressure.
Due to the high viscosity of paste materials, strong discharge force is required. The piston system ensures stable flow even for thick or partially solidified products. Anti-drip nozzles ensure clean cut-off after each cycle, preventing stringing or residue formation at the container opening.
For industrial applications, bottom-up filling can also be used to reduce air entrapment and improve filling consistency. After filling, containers move to downstream processes such as capping, sealing, labeling, and final packaging. The entire workflow is coordinated through a PLC system to ensure stable and synchronized production.

Maintenance and Operation
Paste filling machines require regular maintenance due to the sticky and dense nature of processed materials. Daily cleaning includes flushing pipelines, removing residue from hoppers, and cleaning nozzle surfaces to prevent buildup.
Weekly inspections should focus on piston sealing integrity, valve movement stability, and nozzle performance. Any worn sealing components should be replaced promptly to maintain dosing accuracy.
For heated systems, temperature control units must be checked regularly to ensure stable viscosity conditions. Proper lubrication of mechanical components is necessary to maintain smooth operation under high-pressure conditions.
Routine maintenance ensures consistent filling accuracy, hygienic operation, and long-term machine reliability.
