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. FeaturesFrom single stations with safety frames to fully integrated stationsCovering chemical and pharmaceutical designVarious docking heads depending on powder toxicity up to OEB 5Various construction materialsCIP OptionsWeighing systemPneumatically operated massaging units (bottom or side)Suction hopper with integrated delumper / fluidizationElectric or pneumatic chain hoistBag reclosing deviceCombined bag emptying and big bag emptying
