Big Bag Handling

Bottom Discharge Stations

The big bag emptying stations of Dec are based on a modular design.


This allows to be ideally equipped with systems for each product’s characteristics with corresponding docking systems for non-potent to highly active powders.


Depending on the product flow, there is a range of discharge devices or lump breakers available. With the use of load cells, it is possible to dose accurately into the receptacle.

A simple connection head with double tube and a two hand lever mechanism ensures that the big bag outlet spout has a dust tight connection.

For primary containment requirements, a SafeDock System can be used for a contained connection and the emptying of standard big bags using a single liner including the side sleeve bag-in bag-out concept.
For higher containment, the DCS® Docking can be used providing both primary and secondary containment.
If process and safety requirements are more restrictive, the use of the PTS Powder Transfer System® is recommended rather than emptying by gravity as it ensures complete big bag emptying and full dust evacuation prior to disconnection.
In this instance,  it is possible to use a single station to charge multiple equipment.
