Loss-In-Weight Fillers

Systems that measure how much product has been dispensed by detecting the reduction in weight of a scale-mounted hopper as product exits the hopper.

Category Explained

Loss-in-weight fillers are precision machinery designed to dispense products by continuously monitoring the decrease in weight of a hopper mounted on a scale during the dispensing process. These systems are adept at handling a variety of materials, from liquids to powders and granules, ensuring accurate and consistent filling based on weight. By adjusting the flow rate in real-time to match target weights, they are essential for applications requiring meticulous weight control and efficiency in packaging operations. Their versatility and accuracy make them suitable for industries ranging from food and beverage to pharmaceuticals and chemicals, where precise measurement and reliability are paramount.

Typical products and applications include:

  • Spices, baking ingredients, and powdered drink mixes: Dispensed into sachets, jars, or canisters with exact weight control
  • Nutraceutical powders and protein supplements: Filled into tubs or pouches for retail-ready packaging
  • Chemical powders or granules: Weighed precisely into drums or industrial containers for safe handling
  • Pharmaceutical ingredients: Metered into capsules or small containers with tight dosage tolerances
  • Coffee, rice, or grains: Portion-controlled for retail packaging in foodservice or consumer markets

Additional Considerations:

  • Ideal for high-precision applications: Especially effective for small fills or high-value materials
  • Continuously adjusts flow rate: Real-time weight feedback ensures consistent accuracy
  • Reduces giveaway and material loss: Tight control over dispensed quantities minimizes overfilling
  • Handles a wide range of product types: Works well with dry, fine, granular, or even some liquid materials
  • Integrates with automated lines: Commonly used in multi-head systems or with form-fill-seal packaging machines
