The auger powder filling machine is the industry standard for dosing powders and fine granules. It utilizes a precisely machined auger screw that rotates inside a funnel to dispense a specific volume of product with each cycle. Controlled by a servo motor, it offers exceptional accuracy and repeatability for both free-flowing and non-free-flowing powders.

Inaccurate filling leads directly to product giveaway and lost profits. Our auger fillers are engineered for precision. The servo-driven auger's rotation is controlled with extreme accuracy, ensuring the exact same amount of product is dispensed every time. For non-free-flowing powders, a separate agitator rotates in the hopper to break bridges and constantly feed the auger screw. For applications demanding the highest accuracy, the system can be integrated with a checkweigher to provide real-time feedback, automatically adjusting the fill amount to compensate for variations in powder density.

    • Accuracy: ±0.5% to ±1% (can be improved with checkweigher feedback)
    • Drive System: Servo Motor for auger, AC Motor for agitator
    • Hopper Size: 25L, 50L (standard), larger options available
    • Operation: Semi-Automatic (footswitch activated), Fully Automatic (integrated into line)
    • Tooling: Interchangeable augers and funnels for different fill weights and products

  • FAQ -
    • Q1: What's the difference between "free-flow" and "non-free-flow" powders?
    • A1: Free-flow powders (like granulated sugar or salt) tend to flow easily and can sometimes leak. Non-free-flow powders (like flour or milk powder) are more cohesive, tend to form bridges in the hopper, and require an agitator to ensure they are fed consistently into the auger. We select the right tooling based on this property.
    • Q2: How does the machine handle dusty products?
    • A2: We use several techniques. A dust shroud can be fitted around the funnel to capture airborne particles. For very fine powders, a "bottom-up fill" feature raises the container so the nozzle is always just above the powder level, minimizing dust clouds. We can also integrate a port for a dust extraction system.
    • Q3: How do you change from filling 50g to filling 500g?
    • A3: It's a two-step process. First, you may need to swap the auger screw and funnel for a larger set (a quick, tool-less change). Second, on the HMI (touch screen), you simply enter the new target weight. The system automatically calculates the required number of auger rotations.
    • Q4: What is "checkweigher feedback" and when is it needed?
    • A4: A checkweigher is a scale placed after the filler that weighs each filled container. It sends a signal back to the filler's control system. If it detects a trend of slight over- or under-filling (due to density changes), it tells the filler to automatically adjust the auger rotations up or down. It's used when accuracy is absolutely critical and product cost is high.
    • Q5: Is the system difficult to clean?
    • A5: No, our designs prioritize easy cleaning. Hoppers are often split or on hinges for quick access. The auger, funnel, and agitator can be removed in minutes without tools, allowing for thorough cleaning between product changeovers, which is critical for preventing allergen cross-contamination.
