Sanupharm has specialised in compacting solutions
Homogeneous granules by dry granulation

With our powerful compactor, active ingredient mixtures are processed into granules in the food and pharmaceutical industries. This process is known as compacting, dry granulating or simply granulating. We make this process possible for functional raw materials for small, medium and large production quantities.

Powdery chemical, pharmaceutical and mineral products can be brought into a compact form by compacting and dry granulation. For this purpose, the material is fed to the compactor in a dosed manner and compacted between two rollers under extremely high pressure. The end product has a higher bulk density, is dust-free and has good flow and dosing properties. The compacted material is not only easier to handle than the dusty powder, but due to its high density it also takes up less space and is therefore cheaper to transport and store.

We are also able to process very hygroscopic or temperature-sensitive products and convert them into dust-free, free-flowing compacts of any grain size. The process usually leads to a temperature increase of only 20 - 30°C for a short time and does not require any binding agents. After compaction, powders and bulk materials that originally had only limited free-flowing properties have good flow properties and are therefore easier to dose.

Homogeneous granulates through dry granulation

In pharmaceutical production, the goal is to achieve a homogeneous distribution of all powder components that no longer allows segregation of the individual components. However, bulk materials that do not consist of largely identically sized particles can segregate again. Here, too, it can be useful to compact the mixture to prevent segregation. This ensures that each unit contains the same proportions of the respective mixture components.

The process engineering advantages of our dry granulates:

  • Compaction of bulk materials
  • Flowable granulates with homogeneous distribution of the active ingredients
  • No binder necessary
  • Increase in bulk density
  • Selectable granulate sizes
  • Low heating
  • Good dosing capability
  • Dry process
