The best possible quality standard in classic solids-liquids-separation

Inverting Filter Centrifuge HF: Fully moveable housings and cleaning in a closed condition

Heinkel „HF 1300“ Inverting filter centrifuges

The slurry is delivered to the process chamber which is a rotating drum a feed pipe. The filling step is usually controlled through a load cell based weight control system optionally control can be by time or volume.

The drum spins at a pre-set value chosen from the speed range of the individual machine. The filtrate passes through the filter cloth which lines the process chamber and the solids collect and build up on the filter cloth to form a cake of material.

Wash liquid is introduced and controlled in the same manner as the slurry. Due to the homogeneous cake build-up each part of the solid cake will be washed to the same quality.

The separated solids are discharged by inverting the filter cloth through the axially movement of the shaft, while the bowl remains rotating at a low speed.

HEINKEL developed the inverting filter centrifuge in the early 70’s. The new technology produced residual heel free high quality product in an automated manner.

The technology has stood the test of time and is accepted as the standard solution in the field of solid liquid separation. Today we benefit from many years of experience.

The core design upon which our reliable and robust design was based of discharging separated products by inverting the filter cloth is at the heart of our technology to-day.

HEINKEL Inverting Filter Centrifuges have been used in numerous applications to separate high quality solid materials. Continuous research and optimization of the centrifuge and its associated sub-systems are the foundation of today’s very high quality standard.

In order to fulfill the demands of the pharmaceutical industry, HEINKEL has eliminated hydraulic systems with Inverting Filter Centrifuge design. Industry standards including cGMP or GAMP have been recognized and used as the guide for our design team. Our achievements include the development of industry leading CIP systems and accessibility through the development of fully moveable housings.

Through it’s completely sealed process chamber and fully automated, uninterrupted mode of operation; HEINKEL Inverting Filter Centrifuges fulfill the highest safety standards and guarantee maximum safety for the operating personnel, the environment and the product. The safety level of a HEINKEL Inverting Filter Centrifuge always conforms to current regulations. We strive to set centrifuge technology standard.
