The unit consists of a double cone shaped drum that is mounted in such a manner as to allow rotation about an axis. The Double Cone drum has a valve at the one end and a lid at the other. The lid allows for inspection of the inside of the double cone drum as well as loading of the material / ingredients required for mixing into the “drum”. This can either be done manually or by means of a vacuum transfer system. The lid therefore also facilitates connection of the vacuum transfer systems’ piping to the Double Cone drum. Both the lid and the valve allows for a tight and positive seal so that material will not leak from the mixer during the mixing process thus minimizing cross contamination and thereby decreasing operator exposure risks.
Powders or granules are removed from the Double Cone drum via the outlet/valve. The butterfly valve complies with cGMP design and can be quickly disassembled and reassembled for cleaning purposes. Operation is by manual turning of the valve handle. The valve has locking position to prevent it from creeping.
The Double Cone Mixer is controlled with a PLC allowing user interface through a HMI touch screen. This interface can be a remote panel mounted to the wall. Safety precautions include a safety beam or switch mounted either in front of the Double Cone Mixer or on the cubicle door. The drive and electrical components and connections as well as the electrical cabinet are housed in the one support column. Access is via two environmentally protected/sealed side panels.
The frame is constructed from 3CR12 Stainless Steel, covered/cladded with 304 Stainless Steel and the construction material for the Double Cone/drum is 316 Stainless Steel. Direct product contact surface finishes comply with European Hygienic Engineering & Design Group (EHEDG) recommendations of 0.8 m Ra or better using 220 grit polishing methods. Frame Cladding is supplied with a Satin Finish.
There is no counter rotating intensifier bar present although it is possible to order the Double Cone Mixer with such a bar present.
