    Multihead Weighers

    What Is A Multihead Weigher?

    A multihead weigher is a rapid, precise and efficient piece of machinery that is used to pack both food and non-food products. In the food production and processing industries, multihead weighers are an important piece of equipment for a wide range of organisations allowing food products and ingredients to be measured quickly, accurately and efficiently.

    What Do Multihead Weighers Do?

    Multihead weighers are responsible for generating precise measurements of products. They are very valuable pieces of equipment due to their ability to operate with high levels of accuracy, speed and efficiency.

    Multihead weighers are able to measure a wide range of product types including everything from leafy greens and vegetables, cooked products and dry foods to frozen foods, fruits, nuts and seeds.

    Multihead weighers are also used to accurately fill a range of packaging and containers including bags, trays, tubs, buckets, boxes, jars and even to distribute ingredients into other machines. They are also sometimes used to weigh individual packs into multipacks.

    A Brief History of Multihead Weighers

    The Japanese food company, Ishida, invented the multihead weigher back in the 1970s. It was a machine that revolutionised the food industry because of its high speeds and accuracy.

    The earliest use of the invention was limited to the mere weighing of vegetables. However, during the 1980s, multihead weighers began to be used for the weighing and packaging of confectionery and snacks. In today’s food industry, thanks to the precision and rapidness of these machines, they are used to weigh almost all food products on the market, including meat and fish, dairy, and grains. Complex products such as ready meals are also manufactured using multihead weighers.

    How Do Multihead Weighers Work?

    Multihead weighers function by having a number of ‘hoppers’ ordered into columns. Each column is equipped with a weighing head.

    First, the product is fed to the top of the multihead weigher where it is released into hoppers. Next, the machine's computer system will determine which hopper combinations are closest to the target weight - this is typically 100 grams.

    Then, all hoppers of an optimal combination discharge their products into a weigh hopper underneath (once it becomes clear). The process then repeats with a new product.

    Benefits Of Multihead Weighers

    Multihead weighers offer a number of major advantages that improve the efficiency of food production. Let's take a closer look at some of these below.

    Greater Efficiency

    Multihead weighers are highly valuable because they enable food manufacturing companies to meet market demands. Performance is significantly enhanced when you get work done with a high-speed and piece of machinery as opposed to human hands.

    Not only are multihead weighers fast, but they are also immensely accurate. The advanced technology used inside the machine avoids mistakes that manual food packagers can make, like misinterpreting size and miscalculating weight. Multihead weighers can offer companies a significant increase in food production efficiency and enable manufacturers to maintain high-quality products.


    More Choice Of Bags

    A huge variety of bags can be filled using these machines. From large catering bags to very small bags for products like crisps, all bag sizes can be processed with the utmost precision and efficiency. Multihead weighers are used to fill all sorts of things from bags, trays, tubs, buckets, boxes, jars and even other machines, as well as weighing packs into multipacks.


    Mix-Weighing


    Multihead weighers have the capacity to hold and process up to eight mixed components very rapidly and accurately. Companies that utilise mix-weighing in food production will find that multihead weighers make the whole process more practical.

    Products with a number of different components or ingredients can be mixed on a multihead weigher. The weigher is divided into sections, each with its own in-feed. For instance, a cereal containing dried fruit and nuts in addition to lower cost ingredients such as oats of flakes could be weighed on a multihead with eight heads serving each of the more costly ingredients, plus four heads designated to the others — therefore ensuring that ingredients are correctly distributed into the product in the desired ratios.
