HTG / HBG / SinglePot

The Hüttlin High-shear mixer technology is availabe as HTG (Hüttlin Top-Drive Granulator) or HBG (Hüttlin Bottom-Drive Granulator) up to batches of 720 kg at a density of 0.5 kg/l.

The innovative Gentlewing agitator offers excellent mixing and granulation properties and the flexibility to use 20%-80% of the gross volume with minimized residues at the same time. Based on equal bowl and Gentlewing dimensions, there is no process difference between the top and bottom drive version.

The product line is available in sizes from 150 to 1800 litres bowl volume. It s designed to operate as stand alone high-shear mixer, or in line with a HD/HDG/HDGC fluid bed. For special requirements e.g. effervescent single customized pot versions with vacuum drying or solvent recovery are available. The HTG/HBG is designed for customized containment upgrades to handle high potent APIs.

  • Application Examples


    • Maximum mixing quality with minimum mechanical stress on the product
    • Minimum wall caking due to very close clearances between the product vessel and Gentlewing
    • Excellent discharge due to Z-design of the Gentlewing impeller
    • Eff ective drying without tilting or microwave technology


    • Highly effi cient gas distribution over 360° for considerably higher drying homogeneity
    • Shorter drying times due to continuous, eff ective strip gas feeding

    Discharge valve

    • The discharge valve design enables uninterrupted discharge, as the discharge velocity is not
    • controlled by means of the valve opening, but by extremely low impeller speed


    • The first CIP concept, which signifi cantly reduces cleaning times and ensures highest cleaning quality
