High‑speed, high‑precision packaging for dairy powders with controlled dosing and moisture protection
The Vertical Granulated Powder Packaging Machine is a vertical form‑fill‑seal (VFFS) system specifically engineered for the packaging of fine and granulated dairy powders, including milk powder and whey powder, with production capacities of up to 80 bags per minute.
The system integrates a PLC‑controlled auger filler (vertical screw doser) designed to deliver consistent and accurate weights, even when processing hygroscopic powders or products with variable bulk density. All product‑contact components are manufactured in sanitary stainless steel, ensuring compliance with dairy hygiene standards.
Powder is fed from a hopper equipped with automatic level control, which maintains a constant powder column above the dosing screw. This controlled head pressure is critical to stabilize powder density and ensure that each auger rotation dispenses an identical mass, minimizing weight variation and product giveaway.
Once filled, the package is immediately sealed by a high‑integrity jaw sealing system, creating a hermetic closure that prevents moisture ingress. This protection is essential to preserve solubility, flowability, and microbiological quality of high‑value dairy powders throughout storage and distribution.
Key benefits
• Controls volatility and bulk‑density variation in powdered milk and whey
• High‑precision volumetric dosing with PLC control
• Minimizes loss of high‑value product through accurate filling
• Protects hygroscopic powders from ambient moisture
• Prevents product segregation and reduces contamination risk
The Vertical Granulated Powder Packaging Machine delivers repeatable weight accuracy, hygienic operation, and moisture‑tight packaging, making it a reliable solution for modern dairy powder processing lines.
Main Features and Advantages
Vertical Auger screw dosing: The vertical Auger screw precisely doses free-flow and non-free-flow powders, adjusting rotation speed to product type to guarantee fill accuracy for milk powder and formulas.
±1% accuracy for free-flow and non-free-flow powder: Load-cell weight control system with real-time feedback automatically corrects dosing, minimizing waste and ensuring regulatory compliance of net weight.
VFFS system for milk powder and formulas: Vertical form-fill-seal architecture from reel designed for dairy powders, with optional atmosphere control for MAP or partial vacuum packaging.
Hermetic sealing with atmosphere control: High-temperature transverse sealing for high-barrier multilayer films, ensuring moisture and oxygen impermeability to preserve milk powder quality throughout its shelf life.
