Variable Density Twin Screw Extruder & Spheronizer 700 Extrusion and Spheronization System 150 kg per hour

This pharmaceutical grade wet granulation extrusion-spheronization system comprises of two freestanding machines; the production scale Twin Screw Extruder (VD-TSE70) and the Spheronizer 700 (S700). 
    • Extrusion and spheronization system for production up to 150 kg per hour of extrudate and pellets
    • Easy to clean equipment means you can change between different materials effortlessly during production
    • Suitable for use in a range of industries including  pharmaceutical, chemical, cosmetics, aquaculture, petrochemical, food and more.

 

 

Description

This 150 kg/hour wet granulation extrusion-spheronization system is made up of:

  • The Variable Density Twin Screw Extruder (VD-TSE70)
  • The production scale Spheronizer 700 (S700)

Designed for continuous or intermittent production within industrial environments. An example of reliable and efficient British engineering at its best - this is the option for your pellet production.

This extrusion-spheronization system gives you the ability to vary the density of the extrudates or pellets.  This allows you to fine-tune your process to be ideal for your product properties and the intended use of your pellet or extrudate. 

Scale-up your formulation development from any bench-top extruder. If you have not completed your laboratory formulation development then you might consider the bench-top Variable Density Extruder or the Multi Lab Scientific as the VD-TSE70 is the logical next step in the scale-up pathway.

Twin Screw Variable Density Extruder

This surprisingly compact and efficient extruder has produced up to 200 kg of extrudate per hour using axial extrusion.  A range of different die patterns (hole diameter and depth) and shapes (such as clover-leaf and trilobe holes - suitable for industrial materials in the petrochemical and catalyst industries) are available.

 

Caleva Spheronizer 700

Caleva spheronizers have been the industrial production standard for over 50 years. Our Spheronizer 700 (S700) is the safest and most advanced currently available.  You can have confidence based on Caleva's experience and focus on the provision of large-scale spheronizers that are in used in production by both large manufacturers and smaller contract manufacturers around the world.

Recommended Spares & Consumables

The product manuals fully describe our recommendations for consumables and recommended spares.  All spares and consumables are designed for robust use.

Consumables are items that are expected wear with normal use, or that may be misplaced during the disassembly and cleaning procedures.

Recommended spares should be considered based on the materials used in the equipment and an appreciation of the wear rate expected.  Pharmaceutical materials generally have a low wear rate whereas catalyst materials have a higher wear rate.

The parts that wear are as follows:

Spheronizer:

  • Spheronizer Disc
  • Adaptor Shaft Seal

Extruder:

  • Left Hand Screw Auger
  • Right Hand Screw Auger
  • Left Hand Pressing Cam
  • Right Hand Pressing Cam
  • Extrusion Barrel
  • Dies

We recommend a regular review of your spare parts requirements for the following reasons:
  • Maintain higher outputs and reduce cleaning turnaround
  • Share the wear rate - a second set ready to install at cleaning phases makes for a quick turnaround and shares the wear
  • In applications where wear rate is going to be high then these parts will need to be replaced regularly - having spares to hand will help avoid any unnecessary downtime.
