Top Discharge Station for Big Bag Emptying

Partial emptying of big bags is a challenge as it is usually not feasible to quickly re-close the big bag when the discharge spout is full of product. Iris valves or similar devices could be used for this purpose, but product must be flowing in order to have the possibility to re-seal the spout which prevents any accurate dosing. Dec has solved this problem by developing an automated discharge station where big bags are emptied from the top by using a suction lance connected to the PTS Powder Transfer System.
