The BEUMER bag tester is a testing device that is easy to transport and enables users to determine the venting capacity of any type of valve bag — including all paper and plastic layers and glued areas. The determined parameters can be used to optimise the manufacture of bags or check conformity with specifications.
Bags filled with bulk material are stacked flat on pallets after being closed. These stacks are only stable if the air has been removed from the bags lying on top of each other. Therefore, the remaining air needs to escape from the filled bags before they are closed. The quicker this happens, the higher the filling capacity. The device provides users with important information on the filling behaviour of each bag.
A pressure-compensated flow control valve on the device constantly increases the volume flow rate until a steady pressure of 50 mbar is reached. With this pressure, the user can read the current volume flow rate, which indicates the air permeability, from the flow rate meter. A filling spout with inflatable sleeve seals the bag valve during the airflow measurements. The scope of supply includes an additional inflatable sleeve for valve widths of up to 200 mm.
The tester can be easily operated with the digital display unit. It is quick to use and novice users can operate it without much briefing. It is designed for mobile use and weighs 14 kg.
