Multihead weighers are high-speed, high-accuracy systems designed specifically for portioning solid, free-flowing, and irregular products. Often referred to as “combination weighers,” they are built for high-output, reliable, and precise dosing for integration with baggers, tray lines, and other packaging machinery.
These machines are the essential solution for the food, snack, confectionery, and frozen food industries. They are used to create precise target weights for a vast range of products, including irregular-shaped items (crisps, biscuits), granular goods (nuts, coffee beans), and fresh produce (salad leaves, cherry tomatoes).
By integrating high-speed computing with multiple individual weighing buckets, these machines provide an incredibly efficient and accurate way to automate weighing, drastically reducing product “giveaway” and maximising line efficiency.
Multihead weighers are the definitive solution for high-speed, high-accuracy portioning, offering unmatched precision and a dramatic reduction in product waste.
Unmatched Accuracy & Giveaway Reduction This is the core purpose. By calculating the best “combination” of weights from multiple heads, the machine hits the target weight with extreme precision (often within a single gram), virtually eliminating the costly product “giveaway” (overfilling) common with other methods.
Exceptional High-Speed Throughput A single multihead weigher can perform hundreds of weigh cycles per minute (e.g., 60-140+ “dumps” per minute). This exceptional speed is designed to match the output of modern high-speed VFFS baggers and pre-made pouch machines, eliminating weighing bottlenecks.
Superior Product Versatility Multihead weighers are not limited to one product type. They are engineered to gently handle delicate items (crisps, salads), sticky items (confectionery, dried fruit), frozen products (peas, chips), and even mix multiple components (e.g., nuts and raisins) into a single, accurately weighed pack.

The machine is designed with multiple weighing heads (e.g., 10, 14, 20, or 24), each containing its own high-precision load cell. More heads provide the computer with more combinations to choose from, increasing both speed and accuracy.
Product is moved from a central hopper to the individual weigh heads via a system of precisely controlled vibrating radial feeders. The vibration amplitude is tailored to each product to ensure a consistent, even flow for weighing.
This is the "brain" of the weigher. In a fraction of a second, the processor reads the weights in all heads, calculates all possible combinations, and selects the one combination that is closest to the target weight without being underweight.
Each "head" typically consists of two buckets. A pool hopper (or feed bucket) holds a charge of product, ready to instantly drop it into the weigh hopper (or weigh bucket) as soon as it has discharged, ensuring the machine never waits for product.
Once the correct combination of buckets is chosen, they all dump simultaneously into a synchronised discharge chute. This gathers the complete portion and funnels it cleanly and quickly into the packaging machine (like a bagger or tray sealer) below, timed perfectly with its cycle.

The computer takes weights from multiple buckets and chooses the specific combination that hits the target weight with the lowest giveaway.
Generally, more heads (10, 14, 20) lead to higher speeds and better accuracy.
Yes, by using “dimpled” or embossed stainless steel surfaces to prevent product adhesion.
No; modern weighers feature tool-less removal of all hoppers and feeders for fast sanitation.
By reducing giveaway to under 1g, it often pays for itself within months on high-value products.
