Description

HECHT's continuous centrifuges are vertical filtering centrifuges, designed for uninterrupted solid/liquid separation in large-scale industrial processes such as mining, chemistry and food, where 24/7 processing and maximum throughput are essential. These centrifuges combine high capacity (100-250 L/hour medium, 250-500 L/hour large, up to 500-1000+ L/hour industrial) with a compact design, and continuously remove sediment via a rotating screw without interrupting processing. The closed system guarantees zero product loss and more than 99% separation efficiency, also suitable for OEB 1-5 activities thanks to zero fugitive emissions. A titanium shaft and industrial-strength design ensure 99.9% proven uptime, and the centrifuges are GMP Annex 1 (2022) compliant, GAMP 5 validatable, with built-in FDA 21 CFR Part 11 data logging for 24/7 audit recording. Thanks to favourable energy consumption and high throughput capacity, the payback period is typically 2 to 3 years.

Particularly in sectors such as mining, chemicals, and food processing, these centrifuges offer a reliable solution for intensive separation processes.

Frequently asked questions about continuous centrifuges

What is a continuous centrifuge and why is 24/7 processing important?

A continuous centrifuge is a closed system for nonstop processing of large volumes. 24/7 processing is important because: (1) maximum throughput with zero downtime, (2) cost savings per litre, (3) consistent product quality, (4) positive ROI.

How many L/hour can the continuous centrifuge process?

Medium: 100–250 L/hour. Large: 250–500 L/hour. Industrial: 500–1000+ L/hour. Scalable to your production needs.

How does the automatic sediment discharge work?

A rotating screw continuously removes sediment while processing continues. Zero interruption. Automatically controlled cycle. Zero downtime.

Is the continuous centrifuge GMP compliant?

Yes. GMP Annex 1 (2022) compliant, GAMP 5 validation available. FDA 21 CFR Part 11 data logging built-in. 24/7 audit trail logging.

How much product loss occurs in 24/7 operation?

Zero product loss. Closed-system design. >99% separation efficiency. Optimal recovery over the full production cycle.

How reliable is 24/7 continuous processing?

Very reliable. Titanium shaft. Industrial-strength design. Preventive maintenance planning included. 99.9% uptime proven.

Can the continuous centrifuge handle OEB 4–5 activities?

Yes. OEB 1–5 compliant. Closed system with zero fugitive emissions. Continuous dust-free processing. Suitable for critical operations.

How fast is the ROI for continuous centrifuges?

Very positive. Optimal energy consumption. High throughput capacity. Labour costs minimised. ROI: 2–3 years.
