The primary role of a hopper is to store raw materials and products, regulating and controlling their entry into production lines, packaging areas, and more. The method of transferring products from sub-hoppers varies depending on the type of product, and transfer systems such as conveyors, vibration motors, and transvibration can be used.

In the design of hoppers for products with high weight and density, such as potatoes, it is crucial to control the substantial weight on the conveyor beneath the hopper. The objective is to ensure that the entire weight of the potatoes inside the hopper is not placed directly on the conveyor.

These types of hoppers are engineered in a way that gradually transfers the load to the subsequent conveyor belt, preventing the full weight from being placed on the belt. Neglecting this important consideration can lead to poor performance and significant wear and tear of the equipment. Hoppers are primarily utilized in the French fries production line and the chips production line.
