High-shear mixer granulator

Pharma-Granulat

Process robustness and high efficiency are the main requirements for high-quality granulation in a high-shear mixer. Our technology is based on the unique Gentlewing impeller. The high-shear mixer granulator provides perfect mixing in short time and allows for a wide process window in terms of e.g. tip speed, filling level and mixing duration. At the same time, wall caking and product residues are minimized. The equipment’s intelligent features facilitate safe product transfer via a wet mill into the fluid bed, avoiding operator intervention. For older, already registered formulations, a traditional 3-blade impeller is available.

High-shear mixer technology & features

high-shear-slider

Gentlewing: Convincing mixing and granulation results

The Hüttlin Gentlewing is designed to achieve superior mixing and granulation results. The impeller’s shape matches the contour of the mixing container, while its angled blades ensure forced high-shear mixing of the product.
The prolonged blades further avoid wall caking, resulting in a higher yield.

flugler

Gentlewing or 3-blade impeller: you have the choice!

You have the option to choose between the innovative Gentlewing impeller and a traditional 3-blade impeller for older formulations, which are already registered with this technology.

top-bottom

Top or bottom drive: we offer total flexibility

Our technology is available in a top (HTG) or bottom drive (HBG) execution.
Both share the same geometry, resulting in no process difference between top and bottom drive, achieving consistent high-quality results. The Gentlewing’s design and the vertical chopper support a high batch variability of 20 – 80 %.

Automatic end point detection

Besides time and current measurement, we can additionally offer torque measurement to determine the end point of granulation as a validatable end point value.

Choose your preferred charging option

Depending on your products’ characteristics and your plant’s layout, you can choose between different charging options: pneumatically by continuous or intermittent vacuum or alternatively by gravity filling. Especially for critical products, intermittent vacuum drastically reduces the filter load during charging.

flush-seal

Closed process for the highest safety

In both our top and bottom drive executions, the Gentlewing and chopper shafts are equipped with a purged sealing system. The product container’s lid features an inflatable seal as well as an interlocking device to avoid cross-contamination. It further ensures product and operator safety.

granulean-high-shear-mixer-8

Efficient pharma wall installation

The wall installation enables a true separation of the GMP and technical area, reducing the required space in the pharma room. All drives and supply lines are accessible via the technical area for time-efficient and safe maintenance.

single-pot

All benefits in a single pot

The Hüttlin single pot combines all benefits of the leak-tight top-drive concept with a smart, efficient energy transfer via heated bowl, lid, filter housing and shaft, as well as an optimized vacuum system with optional solvent recovery. This concept meets the highest requirements regarding process times, product quality and handling.

cleaning-concept-1

Cleaning – automated and efficient

Efficiency is one of the main benefits of our cleaning systems. Depending on your requirements, you can flexibly choose either our basic automated cleaning system or the advanced automated UltraClean technology. Thanks to its in-place cleaning, the UltraClean stainless-steel filter significantly reduces cleaning times and ensures reproducible results.

Are you looking for a small R&D tabletop mixer?

Mycromix granulates small amounts of products. Due to interchangeable bowls of 0.5, 1.0, 2.5, 5.0 and 10 liters, you can process a wide range of batch sizes. Mycromix features the same unique Gentlewing impeller and vertical chopper as our production-scale high-shear mixers. Mycromix is available with various options, such as preparation for organic solvents, heating/cooling jackets or a 3-blade impeller. In case you are seeking to expand your R&D capabilities, our Solidlab 1 and Solidlab 2 Plus fluid beds for drying perfectly complement the Mycromix table-top solution.

Unlike most other solutions in the market, the Solidlab 1 comes with our PROVICON control system featuring open recipe creation and management for a time-saving product development.

Use case scenarios

sachet-granulat
Outstanding granule quality

Whether you compress granules into tablets or fill them into capsules or sachets, e.g. for nutraceuticals – our high-shear mixer means outstanding quality for any dosage form.

tabletten-double-layer
Tablets at their best

Outstanding granule properties like smooth flowability and an ideal particle size distribution result in excellent compression characteristics– even at very low API concentration, e.g. for cancer therapy.

brausetablette-02
Easy effervescence

Effervescent tablets support easy oral administration, but prove challenging in terms of production. Our sophisticated single pot system is perfectly suited to produce granules for highly stable effervescent tablets.

capsule-pellets-granules
Yes we capsule

Granules, pellets, and mini tablets are perfectly suited for fixed-dose or personalized combination capsules, e.g. anti-infective drugs. Our fluid bed granulators ensure optimum quality of the individual components.

Frequently asked questions

Granulation is a core step for the production of OSD (oral solid dosage) products, mostly tablets and capsules.

Granules can be applied directly in sachets, be compressed to tablets, or filled into capsules.

The process step of granulation leads to:

  • Improved flowability
  • Narrow particle size distribution
  • Homogeneous distribution of API and excipients
  • Reduction of segregation
  • Increased bulk density
  • Improved compactability
  • Reduction of incoming material variation

There are several granulation methods available, including: Dry granulation with e. g. a roller compactor, and wet granulation in e. g. a high-shear mixer or a fluid bed processor (spray granulation). Each option offers benefits and limitations that need to be considered when selecting the optimal
