Used Receiving hoppers

About second-hand Receiving hoppers

A receiving hopper is often the starting point of a storage intake line for potatoes, onions and other agricultural products. The hopper receives the product from a tipping trailer, acts as a buffer and then feeds it in a controlled flow to the next machine. Think of a sorting machine, a cleaning installation or a conveyor belt.

Depending on the product and the required processing, receiving hoppers are available in various versions. There are models with a single discharge conveyor, several cross discharge conveyors or a roller cleaner that removes soil, dirt and undersized product directly at the intake.

At Duijndam Machines you will find used receiving hoppers from various brands and in a wide range of configurations. View the current stock or read what to look out for when buying a used receiving hopper.

Different versions of receiving hoppers

Not every receiving hopper has the same function. The version determines, among other things, how the product is received, cleaned and distributed to the downstream machines.

Receiving hopper with roller cleaner and two discharge conveyors

A commonly used version is a receiving hopper with a roller cleaning set and two cross discharge conveyors. The roller cleaner separates soil, dirt and undersized product from the marketable product. The discharge conveyors then carry these product flows away separately.

In this configuration, the first cross conveyor discharges the dirt and undersized product. The rear cross conveyor transports the cleaned product to the next machine in the line.

The roller cleaner can consist of different types of rollers, such as spiral rollers or smooth stainless steel rollers. Which version is suitable depends, among other things, on the crop, the amount of adhering soil and the required cleaning effect.

Receiving hopper with three cross discharge conveyors

If, in addition to removing dirt and undersized product, extra product sorting is required, a receiving hopper can be fitted with three cross discharge conveyors.

In this case, the first conveyor discharges soil and undersized product, for example. The second conveyor can be used for additional sorting, while the rear conveyor transports the bulk of the product to the next step.

With this configuration, different product flows can be separated from each other directly at the receiving hopper. This can prevent extra handling further down the storage intake line.

What to look out for when buying a receiving hopper?

When choosing a used receiving hopper, the dimensions of the machine are not the only thing that matters. The way the product is supplied and the required capacity of the storage intake line also play a role.

Width of the tipping trailer

Always check whether the tipping opening is wide enough for the tipping trailer you use to unload the product. A tipping opening that is too narrow can make unloading more difficult and limit the processing capacity.

Width and capacity of the discharge conveyor

The width of the discharge conveyor affects the amount of product the hopper can handle. The actual capacity also depends on factors such as belt speed, product characteristics and the layer thickness of the product on the belt. Therefore, match the hopper to the capacity of the downstream machines.

Required cleaning and sorting

Do you only need a buffer function, or should the receiving hopper also remove soil, dirt and undersized product? And is additional sorting required? These choices determine which roller cleaner and how many discharge conveyors are needed.

Space and connection to the existing line

Take into account the available space and the position of the next machines. The height and discharge direction of the hopper must match the rest of the storage intake line.

Receiving hoppers as part of a complete storage intake line

A receiving hopper usually does not stand on its own, but forms the first step in a larger processing operation. From the hopper, the product can be fed, for example via a duo conveyor or conveyor belt, to a potato sorting machine. A store loader or box filler can also be part of the subsequent steps.

In addition, there are options to divide the product flow further, for example with dirt discharge conveyors, additional conveyor belts or a second sorting step.

In addition to receiving hoppers, Duijndam Machines also supplies various machines for the rest of the storage intake line. This allows us to think along with you about the connection to existing installations or the composition of a complete line.

Transport of used receiving hoppers

Receiving hoppers are machines of considerable size. Therefore, check in advance whether the machine falls within the permitted transport dimensions. Width in particular can be a point of attention: larger receiving hoppers do not always fit on a standard truck and sometimes have to be transported on a low loader or an open trailer.

For transport to destinations outside Europe, shipping by sea, for example via RoRo transport, can also be an option. The most suitable transport method depends on the dimensions, the weight and the destination.
