Description

Batch centrifuges from HECHT are closed centrifuge systems for batch-wise separation of solids and liquids in industrial processes, suitable for the chemical, pharmaceutical, food and energy industries. The range includes both fully automated and manual systems, with a closed, vacuum-sealed bowl that guarantees dust-free, zero-emission processing without product loss and a separation efficiency of more than 99%. Thanks to a modular design and broad configuration options, the centrifuges can be fully tailored to process, product characteristics and safety requirements, with batch capacities from 1-5 litres (lab) to 100-500 litres (production) and rotor speeds up to 3000 rpm, with a batch taking 15 to 45 minutes depending on type and viscosity. The centrifuges are suitable for OEB 1-5 applications, GMP Annex 1 (2022) compliant and GAMP 5 validatable, with built-in FDA 21 CFR Part 11 data logging and a batch changeover time of 20-30 minutes thanks to a standardised bowl removal procedure.

Thanks to their modular design and extensive configuration options, the centrifuges can be fully tailored to your process, product characteristics and safety requirements.

Frequently asked questions about batch centrifuges

What is a batch centrifuge and why is >99% separation efficiency important?

A batch centrifuge is a closed centrifuge system for batch processing of suspensions and emulsions. >99% separation efficiency is important because: (1) minimal product loss, (2) optimal recovery rate, (3) reproducible quality, (4) cost savings.

How does the closed-system design work?

Vacuum-sealed bowl → no vapour release → automatic extraction → dust-free. Zero fugitive emission to the environment. Fully closed-system processing.

What are the batch capacities?

Lab: 1–5 L. Pilot: 10–50 L. Production: 100–500 L. Scalable to your production volume.

Is the batch centrifuge GMP compliant?

Yes. GMP Annex 1 (2022) compliant, GAMP 5 validation available. FDA 21 CFR Part 11 data logging built-in. Validation: 4–6 weeks.

How much product loss occurs?

Zero product loss. Closed-system design. >99% solids recovery. Optimal batch yield.

How fast is the separation?

Rotor speed up to 3000 rpm (Production), up to 2500 rpm (Pilot), up to 2000 rpm (Lab). Batch time: 15–45 minutes depending on batch type and viscosity.

Can the centrifuge handle OEB 4–5 activities?

Yes. OEB 1–5 compliant. Closed system with zero fugitive emissions. Dust-free batch processing. Suitable for critical activities.

How easy is batch changeover?

Very easy. Standardised bowl removal procedure. Cleaning-in-place (CIP) optionally available. Changeover time: 20–30 minutes.
