Mixer Extruder

Mixer extruder is the unique technology extruder range that builds on the proven Umang technology and its benefits. the machine has rotating sigma blades above and a screw cone extruder below, the blades and screw are carefully coordinated so that solvent based product extrusion can be done in this design due to its unique designs.

The outstanding feature of the mixer extruder / mixer cum extruder or sigma mixer extruder range is the integrated and CIP optimized design. Connections, cabling and supplies are completely integrated, covered and sealed so the outside of the machine is smooth and very easy to clean. The innovative discharge blade design and optimized seals inside the extrusion assembly allow for CIP. As a result of this the our mixer extruder is highly flexible, quick product changeover increases productivity and cost effectiveness.

The Mixer extruder ranges from 5 to 500 Kgs/ batch, the design operation with platform and dust-free discharging via a linked mill directly into an IBC. The Mixer extruder can be stand-alone or linked to aspheroinizer or a Fluid Bed Wurster or fluid bed dryer to form an integrated system.

Standard Features for Mixer Extruder :

  • Standard meshes from 500 - 1500 mcrons.
  • Twin counter rotating mixing Blades and cams rotating in counter directions : perfect seals in direct contact with the product on both ends of the blade.
  • Perfect cGMP-design: smooth covering, no external tubing and piping allowing easy cleaning.
  • Screw for extrusion of the material out to a spheroinizer or a fluid bed dryer bowl.
  • Variable perforation meshes ideal for perfect discharge of difficult products
  • User-friendly operator-machine interaction via graphical operator panel 12" Industrial PC software with PROCESS + range of software which helps interlinking all plant equipments to a single system.
  • Flexibility (processes and products) for wet granulation.

Optional Features for Mixer Extruder :

  • Explosion proof design
  • Automatic cleaning (WIP/CIP) of entire system
  • 21 CFR part 11 certified controls.
  • ADVANCE PROCESS + for easy and automated plant control
  • Jacketed / insulated bowl
  • Total containment through up- and downstream split valves and flexible isolation systems.
  • Integration with fluid bed processor possible: perfect closed link for dust-free operation
  • Video monitoring of the process
  • Product feeding both by gravity or vacuum loading system directly from the containers

    Formulation Development

    Our expertise in formulation development extends to the development of all conventional dosage forms. Our strategic alliances broaden the scope to consider many Novel Drug Delivery Systems (NDDS), including transdermal & liposomal delivery systems. We consider multiple approaches to improve the bioavailability of drugs. We have expertise in improving delivery of poorly soluble/ permeable drugs and the capability to screen potentially innovative drugs based on pharmacokinetic properties. We possess pelletization, drug-layering, particle-coating and other technologies to achieve extended release profiles for tablets or capsules.
