Pre-made Pouch Liquid & Paste Packing Machine

A rotary premade pouch packing machine for liquids is a sophisticated piece of packaging equipment designed to efficiently fill and seal preformed pouches with liquid products. Here’s a detailed description of its components and operation:

• Rotary Structure: The machine typically consists of a rotating carousel or turret with multiple stations arranged in a circular fashion. Each station performs a specific task in the packaging process.
• Pouch Feeding System: Preformed pouches are loaded into the machine manually or automatically. They are then conveyed to the filling stations.
• Liquid Filling System: The filling station is equipped with precision liquid filling mechanisms such as volumetric or gravimetric fillers. These fillers accurately dispense the desired amount of liquid into each pouch. The filling process is often controlled by sensors to ensure precise fill levels.
• Sealing Mechanism: Once filled, the pouches move to the sealing station. Here, various sealing methods such as heat sealing, ultrasonic sealing, or zip-lock sealing are employed to securely seal the pouches, preventing leakage and maintaining product freshness.
• Control System: Modern pouch packing machines are equipped with sophisticated control systems, often featuring touchscreen interfaces for easy operation and monitoring. These systems allow operators to adjust parameters such as fill volumes, sealing temperatures, and production speeds.
• Hygienic Design: Given that the machine handles liquid products, it is typically constructed with materials that are resistant to corrosion and easy to clean. Hygienic design principles are followed to prevent contamination and ensure product safety.
• Safety Features: Safety interlocks and guards are installed to protect operators from hazards such as moving parts and hot surfaces.
• Output Conveyor: Once sealed, the filled pouches are discharged onto an output conveyor, where they can be collected for further packaging or distribution.

Optional Stations:

•  Date Coding/Printing: Some machines may include a station for printing expiration dates, lot codes, or other product information directly onto the pouches.
• Gas Flushing: In applications where product freshness is crucial, a gas flushing station may be included to replace air inside the pouch with inert gas (such as nitrogen) to extend shelf life.
• Zipper or resealable pouch application: Some machines are capable of applying zippers or other resealable features to the pouches, enhancing consumer convenience and product freshness.
