In the food industry, a multi-head scale is a type of weighing machine that is used to weigh bulk quantities of products, such as fruits, vegetables, and grains. These scales typically have multiple heads or platforms, each of which can weigh a different product at the same time. This allows for efficient and accurate weighing of large quantities of products, and can help to improve the speed and efficiency of the food packaging and distribution process. They are often used in places like supermarkets, warehouses, and food processing plants.
