Milk Powder Weighing Production Line designed for high-precision infant formula and nutritional powder packaging
Keypack Intelligent Milk Powder Weighing Production Line delivers 30-120 bottles/min production capacity with dual weighing system accuracy ≤±0.5%. It integrates automatic can sterilization, twin-head filling, vacuum nitrogen flushing, and laser coding in a complete automation workflow. Ideal for infant formula production, nutritional powder packaging, protein powder canning, and dairy production facilities requiring GMP compliance.
Product Overview
This automatic powder packaging line is engineered specifically for milk powder canning operations across food-grade and pharmaceutical applications. The powder canning line features a fully automated twin-head filling production line with PLC control and touchscreen HMI for intuitive operation. The dual weighing system performs coarse filling followed by precision filling, ensuring each can meets target weight specifications while maximizing yield rate.
The Keypack Intelligent (kunbupack) Milk Powder Weighing Production Line incorporates vacuum nitrogen flushing technology to control residual oxygen levels, extending shelf life for sensitive nutritional products. Integrated dust extraction maintains a hygienic production environment, while the sealed modular design protects both operators and equipment. The nitrogen vacuum sealer system ensures product freshness and prevents oxidation during storage.
Built with food-grade materials and hygienic design principles, this complete automation system handles empty can sterilization, automatic filling, vacuum sealing, laser coding, lid pressing, and discharge—all within a single integrated production line. The machine's universal design allows quick changeover between different can sizes by replacing simple tooling components, making it adaptable for multiple product formats.

Key Features and Machine Characteristics
-
Dual Weighing System for High Accuracy: Two-stage filling process with coarse and precision filling ensures final product weight meets specifications, improving yield rate and reducing material waste. First weighing feedback determines precision fill amount, second weighing confirms final accuracy.
-
Complete Automation with Multi-Point Detection: Automated workflow includes can presence detection, coarse filling detection, first weighing checkpoint, precision filling detection, and final weighing verification. One-touch startup after setup requires minimal operator intervention, reducing labor costs.
-
Vacuum Nitrogen Flushing for Extended Shelf Life: Integrated nitrogen vacuum sealer removes oxygen and replaces with inert gas, controlling residual oxygen levels to prevent oxidation and maintain product freshness for sensitive infant formula and nutritional powders.
-
Dust Extraction and Hygienic Design: Built-in dust collection system during filling operations maintains clean production environment. Sealed construction separates work area from control panel, protecting operators and equipment while meeting food-grade packaging standards.
-
Universal Design for Multiple Can Formats: High versatility allows one machine to handle various packaging materials including 307#, 401#, 502#, 300# metal cans and PET containers. Quick changeover achieved by replacing simple tooling components while main machine body remains universal.
-
Modular Construction for Line Integration: Compact modular design facilitates integration into existing production lines. Enclosed structure maintains environmental cleanliness while modern aesthetic design presents professional appearance suitable for GMP-compliant facilities.
-
PLC Control with Touchscreen HMI: Advanced automation with programmable logic controller and user-friendly touchscreen interface enables flexible operation, easy maintenance, and precise parameter adjustment for different product formulations.
-
Integrated Can Sterilization and Cleaning: Automatic empty can blow-cleaning and sterilization, automatic can body cleaning after filling, and automatic lid pressing ensure hygienic packaging throughout the entire process.
Application Areas
