THE LÖDIGE
MIXING GRANULATOR

MACHINE TYPE

The high-shear mixer is a system for mixing, granulation and sieving of pharmaceutical powders and granulated products. Moreover, it is suitable for a wide range of cosmetics and food products. A three-bladed mixing tool rotates in a vertical, cylindrical mixing vessel close to the wall and to the bottom of the vessel. The shape and peripheral speed of the mixing tool create a vortex-like circulation of the mix. This product movement ensures very short mixing times in conjunction with excellent mixing quality and permits build-up of granulated products. A separately driven chopper is used for breaking up any agglomerated products as well as for moistening and granulation. Liquid addition is either gravimetric or uses a pump to add liquid directly to the effective range of the chopper, so that the best possible distribution is ensured. The optional wet sieve on the discharge ensures a completely homogeneous distribution of the granulate size.

PHARMACEUTICAL CONTROLS

The PC/PLC-based control system is equipped with a SCADA system WinCC and designed to be compliant with CFR-21 Part 11. The updated user interface permits intuitive machine operation in service and automatic mode for production and cleaning operation. All process parameters, trend curves and messages are displayed in a clear overview. Batches are documented in hard and soft copies. If a warning or alarm is triggered, the entire screen changes to a signal colour to immediately get the operator’s attention.
