Peeler Centrifuges

Peeler centrifuges can offer both a filtering and sedimenting/decanting capability, and is particularly suitable to processing materials in the ultra-clean environment of the pharmaceutical and fine chemical industries. Two types of peeler centrifuge exist: a heavy-duty chemical design and a GMP design.

Peeler centrifuges have either perforated baskets and screen membranes for filtering processes or solid bowls for decanting. The centrifuge has a fully opening front-end casing, which allows safe operator inspection of the interior. It also posseses an automatic peeler knife mechanism for final cake removal which can under certain circumstances allow final solids to be removed at high speeds, though not all products are suitable. In an attempt to automatically remove the troublesome residual heels found in virtually all batch filtering centrifuges most manufacturers install various heel removal devices – a feature that would provide complete batch-to-batch containment as well as increased product yield. High g forces and increased discharge speeds means the peeler centrifuge uses shorter cycle times, which can be adjusted to ensure a range of washing capabilities. It can be used for applications where feed slurry has a low or fluctuating solids concentration.

Manufacturers of peeler centrifuges include Alfa Laval, Comi Condor, Krauss-Maffei and Sharples.
