Centrifugal Peeler



  • A-starch dewatering
  • Corn starch de-watering
  • Potato and cassava starch dewatering
  • A and B-starch separation

Features and benefits:

  • Lower residual cake moisture due to high centrifugal force
  • Excellent wash result
  • High dewatering and filtration capacity
  • Low required space
  • Smooth operation


Centrifugal Peeler is one of the key processing equipment for starch de-watering.

Starch slurry is feed into the rotating centrifuge basket via the hydro cyclone. Normally, the basket is filled with solids up to 75-80% of the basket rim height. The feed step is completed when the filter cake has reached the desired level. The primary filtration of the mother liquor through the filter medium installed in the basket begins with the feed step, and ends once the liquor has immersed into the filter cake. Solids retained on the filter medium after completion of a cycle and discharge of product serves as a filter medium for subsequent cycles.

A cake wash step will often follow the primary filtration step. Wash liquid is introduced through the feed distributor or, for lower wash rates, through a separate spray bar. Immediately following the feed and wash step, which may be carried out at a lower speed, the basket will be accelerated to maximum allowable speed for the cake dry spinning step which ends once the desired residual cake moisture has been reached, or a predetermined period of spin time has expired.

At the end of each centrifuge cycle the filter cake is removed from the basket by a pivoting peeling device equipped with a broad peeler knife. The scraped layers of product are diverted into a trough and discharged from the centrifuge through an inclined chute or a horizontal screw conveyor. To protect the filter medium, a thin layer of filter cake is retained in the basket. This layer, called the residual heel, becomes the filter aid for subsequent cycles.
