When it comes to accurately measuring and weighing products, two of the most popular options in the market are multihead weighers and linear weigher machines. Both are effective solutions for various industries, including food, pharmaceuticals, and chemicals. However, each has its unique advantages and disadvantages that you need to consider.
In this blog post, we'll take a closer look at multihead weighers and linear weigher machines, and help you understand which solution is the right fit for your specific needs. But before we dive in, let's start with the basics.
What is a Multihead Weigher?
A multihead weigher is a computerized weighing system that uses a series of weighing buckets (or hoppers) to pre-weigh products individually simultaneously. The buckets are mounted on a scale, and each one is filled with a small amount of product, typically in the range of 10g to 1,000g, depending on the product type and desired accuracy.
The weight of each bucket is then calculated by a computer, and the combined weight of the buckets that match or come closest to the desired weight is released into a bag or container. This process allows for fast and accurate weighing of a variety of products, including snacks, powdered goods, and frozen foods.
The Benefits of Using a Multihead Weigher
One of the primary advantages of using a multihead weigher is its speed and accuracy. This system can weigh hundreds of products per minute, making it an ideal solution for high-volume production lines. Additionally, multihead weighers can handle a wide range of products with varying shapes and sizes, making them versatile and flexible.
Another benefit of using a multihead weigher is the reduced waste that it produces. Since the system pre-weighs each product before releasing it, there's less chance of overfilling or underfilling, resulting in less product giveaway and improved yield.
What is a Linear Weigher Machine?
A linear weigher machine is a mechanical system that uses a series of vibratory feeders to dispense a specific quantity of product into a weigh hopper. The product is then weighed and dispensed into a bag or container. Linear weighers are commonly used for dry and free-flowing products, such as grains, nuts, and seeds.
The Benefits of Using a Linear Weigher Machine
One of the primary advantages of using a linear weigher machine is its simplicity. This system is easy to operate and maintain, making it an excellent choice for small-scale productions. Additionally, linear weighers are cost-effective and require less investment compared to multihead weighers.
Another advantage of using a linear weigher machine is its accuracy. Since the system dispenses a predetermined quantity of product into a weigh hopper, the chances of overfilling or underfilling are reduced, resulting in less product waste.
Multihead Weighers vs Linear Weigher Machines: Which One is Right for You?
When it comes to choosing between a multihead weigher and linear weigher machine, there are several factors that you need to consider. These include:
Product Type and Size
Multihead weighers are versatile and can handle a wide range of products with varying shapes and sizes. On the other hand, linear weigher machines are suitable for dry and free-flowing products that are relatively uniform in size and shape.
Production Volume
Multihead weighers are ideal for high-volume productions, where speed and accuracy are critical. Linear weigher machines, on the other hand, are suitable for small-scale productions or specialty products with lower production rates.
Accuracy
Both multihead weighers and linear weigher machines are accurate solutions for measuring and weighing products. However, multihead weighers are typically more precise due to their advanced weighing and calculation technology.
Budget
Multihead weighers are more expensive than linear weigher machines, making them a more suitable choice for larger productions with higher budgets. Linear weigher machines are more affordable and require less initial investment.
In conclusion, both multihead weighers and linear weigher machines are effective solutions for measuring and weighing products. When choosing between the two, consider your product type and size, production volume, accuracy requirements, and budget. By doing so, you can ensure that you select the right solution for your specific needs.
