Food industry is continuously aiming to boost productivity, enhance efficiency, and maintain high quality. One of the critical aspects to achieve this is accurate and fast weighing of food products. In the vast sea of weighing equipment, the multihead weigher and linear weigher stand out as two prominent solutions. Let’s dive deep into the unique functionalities of these weighers and how they stack up against each other.
The Basics: Understanding Multihead Weigher and Linear Weigher
A multihead weighing machine consists of multiple weighing units, often referred to as ‘heads.’ These heads work in tandem to weigh products, ensuring precision and high speed. The product is dropped into a central cone and then dispersed to the feed and weigh hopper. The system determines the optimal combination of weigh hoppers to achieve the closest weight to the target. This makes it incredibly efficient for products that need high speed and exact weight.
In contrast, a linear weigher uses vibrating pans to move the product from pans to the weigh hopper. The machine then selects the pan vibratiion grade that is closest to the desired weight. It is a more straightforward approach and is often chosen for its simplicity and cost-effectiveness.

Accuracy and Speed: Multihead Weigher Takes the Lead
In terms of accuracy and speed performance, multihead weighers outperform their linear counterparts. Multihead weighers can handle multiple weights simultaneously, thanks to their many ‘heads.’ The system’s algorithm identifies the perfect combination of hoppers to get the exact target weight, reducing giveaway and ensuring high accuracy.
Linear weighers, although fairly accurate, can’t match the speed and precision of multihead weighers. The single-pan approach, while simpler, isn’t as quick or as accurate, making linear weighers more suitable for smaller operations or products with less stringent weight requirements.
Complexity and Ease of Use: Linear Weigher Shines
When it comes to ease of use and maintenance, the linear weigher holds the upper hand. Its simple design, fewer parts, and straightforward operation make it easier to clean, maintain, and troubleshoot. Linear weighers are often the preferred choice for businesses looking for a more straightforward, budget-friendly solution.
On the other hand, multihead weighers are more complex machines. They require more regular maintenance and may require specialized knowledge or training to operate efficiently. This added complexity can increase the total cost of ownership.
Versatility: Multihead Scale Stands Out
Multihead weighers are incredibly versatile, capable of handling a wide range of product types. They can weigh fragile items like chips or complex mixtures like trail mix with equal precision, even can weigh vegetables, meat, frozen food, ready meals and etc. Some sophisticated multihead weighers can even handle multiple products simultaneously, making them the go-to cho ice for businesses that need flexibility.
Linear weighers are less versatile, better suited to a narrower range of product types. However, for operations focusing on a single type of product, this may not be a significant issue.
Packaging Machine Systems Matching
Multihead weighers are flexible to equip with VFFS, HFFS, premade pouch packaging machine, tray packing machine, Modified atmosphere packaging machines (MAP), vacuum packing machines, thermoforming packing machines and others.
Linear weighers, due to their simpler design, typically paired with vertical form-fill-seal (VFFS) and small pouch packaging machine. Linear weigher packing line makes the automation packaging process more cost-effective when your production volume is small.
Conclusion: Choose Wisely
Choosing between a multihead weigher and a linear weigher largely depends on your specific business needs. For operations requiring high speed, precision, and versatility, the multihead weigher is undoubtedly the better choice. However, if simplicity, ease of use, and budget-friendliness are your main concerns, then a linear weigher would be the more fitting option.
Each weigher brings unique strengths to the table, and it’s crucial to understand these in the context of your operation. Balancing your specific requirements against the capabilities and cost of these weighers will lead you to the most beneficial choice for your food business. As the weighing process is a critical component in maintaining product quality and production efficiency, making the right choice is paramount.
