An integrated impeller mixes inside IBCs

| By Chemical Engineering

3The new Schütz impeller (photo) is a one-way stirring system that is integrated into the screw cap of intermediate bulk container (IBCs). The impeller system is available for all 1,000- and 1,250-L Ecobulk types and fits both the DN 150 and DN 225 filling openings. The component is made entirely of high-density polyethylene (HDPE), so the filling goods will not come into contact with steel later on. The screw cap with integrated impeller is pre-installed in the filling opening of the IBC at the production plant. For filling purposes, the system is either briefly removed or remains fixed in place, depending on the filling process and container configuration. IBCs with impellers form a self-contained packaging system. After filling, the IBC can remain permanently closed and sealed all along the supply chain until the product is to be used. — Schütz GmbH & Co. KGaA, Selters, Germany
