Krauss Maffei Peeler Centrifuge HZ180/7.1 is batch operated filtration centrifuges known for their reliable performance at high capacity. It is used in many processes, primarily in the bulk chemicals, fine chemicals, and food industries.
The horizontal rotor assembly is cantilever mounted and, depending on the application, can be provided with a conventional filtration basket or a specially designed rotary siphon basket. A fully opening housing door provides access to the basket and all process components for maintenance.
Adding variable speed drives and custom-tailored controls and instrumentation enables the Krauss Maffei peeler centrifuge to be optimally adapted to a multitude of processing requirements for peak performance.

Operating principle of Krauss Maffei Peeler Centrifuge HZ180/7.1
– backwashing with mother liquid (or fresh water) to re-suspend the compressed residual heel and restore its permeability. Additionally, the liquid pool created by backwashing on top of the heel will help to distribute the subsequent cycle’s incoming suspension evenly and virtually eliminate the potential for imbalance during the feed step.
– feeding the slurry into the basket with two feed pipes, monitored and regulated by a feed controller. The second feed pipe creates a certain overflow to utilize the whole volume of the basket and remove protein and fine fibers at the same time.
– liquid skimming to remove the remaining mother liquor above the starch cake and which contains protein and fine fibers.
– dry spinning at high g-forces to reduce the residual moisture to 33%
– cake discharge with a large peeler knife at full basket speed and adjustable swivel velocity. The peeled starch is discharged from the centrifuge gently via a screw conveyor.
