What is the difference between linear weigher and multihead weigher?

Understanding Linear and Multihead Weighers

Our company provides two types of weighing systems: linear weighers and multihead weighers. Both use load cells attached to hoppers for product weighing, but they operate on different principles.

How Linear Weighers Work

In linear weighers, each hopper functions independently. Product is fed into a single hopper until the target weight is achieved, making them ideal for applications requiring straightforward and individual weighing.

The Mechanism of Multihead Weighers

In contrast, multihead weighers operate on a more complex principle. Instead of individual hoppers working separately, the hoppers in a multihead weigher work collaboratively. The target weight is achieved by combining the contents of multiple hoppers, which are then discharged together. This design allows for high precision and efficiency, making multihead weighers suitable for products with larger individual weights, such as biscuits, candies, dried foods, and sweets.

A Deep Dive into Multihead Weighers

Multihead weighers, also known as combination weighers, consist of 10 to 28 integrated linear weighers. Instead of filling the exact target weight into each bucket, approximately a third of the target weight is distributed into different buckets. The system then combines the various weights to achieve the total target weight before discharging them into the packaging. This efficient mechanism allows for continuous and speedy operation.

Variations in Multihead Weighers

There are several variations of multihead weighers, including screw feed weighers for viscous products and those with linear orientations for delicate and fresh products requiring accurate feed control. Each hopper is equipped with a highly precise load cell that calculates the product weight. The processor identifies the best combination of weights to meet the target weight before discharging the accurately weighed portion into the packaging system.

The more heads a multihead weighing machine has, the faster and more precise it can calculate and discharge weighed portions. For example, a 16 heads high speed multihead weigher enhances speed and accuracy, optimizing the weighing process.

Gantan specializes in providing high-speed, precise multihead weighers, ensuring top-quality service and becoming a trusted brand among users and packaging OEMs. As a leading supplier, Gantan strives to offer a range of weighing machines, including linear weighers, automatic weighers, and combination weighers tailored to meet customer requirements.
