Applications

Agglomeration 

A high percentage of fine dust and poor flowability often make powdered substances difficult to process when it comes to bottling, measuring and transport. The process of agglomeration changes the physical properties of these products.

A powder's fine particles are fused together using a binding agent to form larger groups of particles, which makes them easier to process. Equally, for many substances it is sometimes only possible to achieve good solubility by increasing particle porosity through agglomeration or instantisation. Substances created through agglomeration ensure a good flow of material and lower dust levels in the surrounding area.

Advantages

• Improves flowability
• Lowers risk of separation
• Reduces percentage of fine dust
• Improved tabletisation
• Instantisation

Basic principle
The starting product (powder) is injected into the fluidised bed processor as a 'fluid', i.e. vigorously mixed in with a heated gas stream and held in a suspended state. Using specially designed two-substance nozzles, the particles are moistened with a suitable liquid. A liquid bridge forms between the individual particles. During the subsequent drying process, these bridges become solidified and thus stabilise the granulate. The blackberry-shaped structure is then dried to achieve the desired final moisture content.
