High-Shear Granulator – VG 65/10

The flexible vertical granulator for efficient scale-up

The VG 65/10 is an efficient high-shear granulator for testing small product quantities: The wet granulator with flexible, temperature-controlled working vessels for mixing and granulating powders has an integrated touch panel and a GMP-compliant design. It is quick to assemble and easy to operate. The vessels can be equipped with additional powder hoppers and various spray nozzles. Thanks to its compact design, it is ideal as a tabletop device. The VG 65/10 is designed for product quantities of 0.1 to 4.5 liters.

Benefits:

  • Flexible thanks to various working vessels
  • Various rotor designs and sieve inserts
  • Compact design

Special Features:

Flexible working vessels

Flexible, temperature-controlled working vessels increase functionality and enable mixing and granulation in a single system. The vessels can be exchanged quickly and easily without special tools. Depending on the application, tilting or swiveling lids with inflatable seals are available for the working vessel.

PRO version

The version in our PRO concept enables granulation with solvents without inerting. The closed system is pressure shock resistant up to 12 bar, ensuring that operating personnel, the product, and the environment are perfectly protected.

High-Shear Granulation Process

High shear granulation, also known as vertical granulation or wet granulation, is a highly developed shaping process for granulation.

The shaping process for granulation takes place in a closed vessel equipped with mixing tools and a chopper. The particles are simultaneously pulverized and mixed while a binder liquid is added. This creates liquid and solid bridges and very dense granules are formed.

Originally, the granulating liquid was poured into the product. Today, we achieve a better-metered distribution via a spray nozzle – a more uniform granulate is produced.

Applications

Solutions and Options

Torque Measurement

The energy required to rotate the impeller is often used as an indicator for determining the granulation end point.
For every user and their different needs regarding torque determination, Glatt provides the appropriate solution. In addition to the standard implementation of measuring the power consumption of the frequency converter, it is also possible to measure the direct power consumption of the impeller motor. Both variants are influenced by interference factors in energy transmission and by potential wear of mechanical components.

If the torque values need to be determined absolutely, Glatt offers a non-contact and calibratable torque measurement directly on the rotor. This enables exact determination of the torque.
