Working Process of Bag-in-box Filling Machines

  • Bag Positioning: Soft bag placed on the roller weighing table
  • Cap Opening: Pneumatic cylinder lifts and positions the cap
  • Filling: The Filling pump and valve deliver product to the filling head
  • Weigh Control: Load cell monitors flow for precise volume
  • Capping: Cylinder presses the cap tightly into the bag neck
  • Bag Removal: The Bag slides down the roller platform for packing

Human–Machine Interface (HMI)

  • Real-time operation display
  • Manual and automatic modes
  • Filling volume presets
  • Delay adjustments (cap opening, filling time, cap pressing)
  • Weighing calibration menu
  • I/O signal monitoring (for troubleshooting)

Before Choosing a Semi-Automatic Bag-In-Box Filler

  • Low-viscosity liquids (water-based beverages, cleaning agents)
  • Medium-viscosity liquids (oils, detergents, sauces)
  • Sensitive liquids that require hygienic contact surfaces

Suitable filling equipment for the Cheertainer bag-in-box should use 316L stainless steel for all product-contact surfaces to maintain hygiene and prevent corrosion.
