A new discharge system with electronic pressure control from this company is used in conjunction with its planetary mixers and multi-shaft mixers for processing high-viscosity applications. After the mixing cycle, the vessel is rolled over to the discharge system, which is programmed to maintain a desired platen pressure. This can reportedly enable automatic and controlled transfer of the finished product straight into the filling line.

The company’s discharge systems consist of a platen that is lowered hydraulically into the mix vessel. The platen is fitted with an O-ring, which rides against the vessel wall as the platen pushes down on the batch. Product is forced out through one or more outlet valves located on the vessel or on the platen. Interfaced to a PLC-based control panel, the discharge system features a cylinder-mounted linear transmitter for precise indication of platen position. When the platen reaches the bottom of the vessel, all product outlet valves automatically close and a vent valve opens as the platen retracts to the up position.
