Operating characteristics: Widest range of applications, chemical or pharmaceutical design, automated discharge with heel removal. Access to process areas allows inspection and facilitates frequent product change.

Suspension is fed in to the centrifuge via a central connection and distributed on the filter cloth. After completion of cake building the wash liquid is introduced via a separate connection. Spinning then takes place to complete the filtration process. The product is extracted by use of the peeler knife and heel removal system, discharging the product through a chute.

Operating characteristics: No product shear, high turn-down, auto-emptying, total containment, guaranteed product discharge, no residual heel. Clean-room execution available.

The inverting filter centrifuge is charged with suspension via a central connection pipe passing through the solids housing. The solids build an even cake on the filter cloth as the centrifuge drum rotates. The cake is washed via the charge connection and spun to complete the filtration. To discharge the product, the filter cloth, fastened to the centrifuge bowl and bowl insert, is inverted by moving the bowl insert in to the centrifuge solids housing. The cake, now on the outer surface of the filter cloth, is easily and completely discharged in to the solids housing while the centrifuge bowl and insert rotate at reduced speed. Discharge takes a few seconds and unlike a peeler system imparts no shear on the product. Total containment is maintained throughout.

For improved liquid solids separation the centrifuge can be equipped with a PAC System. By applying nitrogen to the centrifuge drum the product can be dewatered more effectively. The gas can be heated to dry the filter cake.

 

Operating characteristics: Flexible multi-purpose design, high washing and extraction performance. Perforated bowl for filtration. Non-perforated bowl for sedimentation. Full size or pivot and dip peeler knives. Bottom discharge via chute or screw conveyor. Top discharge via filter bag removal. Pharmaceutical or chemical industry designs.

For process development and customer’s small scale manufacturing requirements Heinkel offers pilot scale centrifuges for rental or purchase. Inverting, peeler and basket centrifuges are available. Tests on rental machines can be performed at the customer’s or Heinkel’s facilities. Combined centrifugation and drying trials can be performed in cooperation with Bolz-Summix.
