About second-hand Dosing hoppers

Dosing bunkers, also known as dosing hoppers, ensure an even and controlled supply of products to a processing line. This makes them indispensable in agricultural processing operations. A dosing bunker can be used for many bulk products to prevent irregular operation, disruptions, or blockages. This is crucial for the proper functioning of the entire sorting line.

Used Dosing Bunkers for Sale Duijndam Machines offers a wide range of used dosing bunkers from well-known brands, suitable for various product types and capacities. On the page of a specific dosing bunker, you will find detailed information, including photos and sometimes videos. If you still have questions, feel free to contact us so that one of our specialists can assist you!


How Dosing Bunkers Work

The product is deposited into the dosing bunkers from cubic crates using a crate tipper or via conveyor belts. The conveyor belt then continuously takes the bottom layer of the product, while the upper layers roll or slide back, ensuring a consistent flow.

Most dosing bunkers have an endless conveyor belt and a soft inner lining to prevent product damage. The speed of the dosing bunker is often frequency-controlled or mechanically adjustable. Some dosing bunkers come with additional features such as a shaking mechanism (vibrating head), roller set, electronic sensor, or remote control.


Applications of Dosing Bunkers 

Dosing bunkers are used to gradually feed bulk products into sorting, washing, or packaging lines. Thanks to this controlled dosing, processing capacity remains constant, and product damage is minimized.

Typical products processed with dosing bunkers include:

  • Flower bulbs
  • Potatoes
  • Onions
  • Red beets
  • Carrots
  • Potting soil
  • Shredded material (such as green waste or mulch)


Difference Between a Dosing Bunker and a Receiving Bunker 

Although dosing bunkers and receiving bunkers have similar names, they differ in function:

  • Receiving bunkers are designed to receive and (temporarily) store products.
  • Dosing bunkers are designed to evenly and systematically release products to the next step in the processing line.

In some cases, both functions are combined in one machine. In that case, a conveyor belt is added to the receiving bunker, allowing it to function as both a storage and dosing bunker.
