HD/HDG/HDGC 100/200/300/400/600/800/1200/2000/3000

The globally proven Hüttlin fluid bed technology enables drying, granulation and coating in one product container of up to more than 1600 kg batches.

The unique air distribution plate Diskjet guarantees very efficient mixing and drying due to a high velocity of process air. The special arrangement of the bottom spray nozzles guarantees excellent quality of granules and homogenous coating of pellets within significantly reduced process times.

The 3-component nozzles ensure long operation times without interruption, as the tip of the nozzels is protected by Microclimate. The process filter system operates with a sequential blow back and providing high yield without interruption of the fluidization. Next to textile filters we can also use UltraClean metal filters. Pressure shock resistant design is standard. Our scale-up software NexStep ensures a sucessful scale-up. PROVICON, our intuitive state of the art control system completes the package.



  • homogeneous airflow ensures optimum exchange of substance and energy
  • the tangential air outlet reduces filter load
  • best product mixing results due to controlled and uniform process air distribution
  • Significant reduction of process time

  • Application Examples

    Perfect mixing behaviour

    The patented process gas bottom ensures fast and thorough mixing as well as short drying periods. Independently of drying conditions, Diskjet produces even fluidization of the entire filling. A homogeneous air stream provides optimum exchange of substance and energy. The tangential gas exit improves the efficiency of the filter system. The high exit speed of process air prevents the product from settling on the bottom resulting in uniform residual humidity of the product and processes with enhanced reproducibility.

    Inline process – overall perfection

    Inline process at Hüttlin means that the high-shear mixer granulator is physically attached to the fluid bed system using a product transfer line. The product is extracted from the high-shear mixer granulator using negative pressure and transported to the fluid bed with the process air. Regardless of whether a cone mill is interposed or whether the product is a difficult one, Hüttlin can rise to the challenge. Minimum transfer times combined with a maximum degree of emptying are proof of this. Closed product handling is proven technology at Hüttlin.
