Laboratory Decanter Centrifuges for Continuous Solid-Liquid Separation
Lemitec decanter centrifuges have been specifically developed for use in laboratories, pilot plants, and process development facilities. Designed as two-phase decanter centrifuges, they enable the continuous processing of small product volumes with throughput rates ranging from 1 to 300 liters per hour.
The achievable throughput depends on the separation characteristics and physical properties of the processed material. This makes the systems ideal for research, development, process optimization, and scale-up studies where continuous separation under realistic operating conditions is required.
Conventional industrial decanter centrifuges typically require significantly higher minimum feed rates than those available in laboratory environments. As a result, continuous separation processes often had to be simulated using alternative batch-based methods. Lemitec laboratory decanter centrifuges bridge this gap by allowing continuous separation processes to be tested, optimized, and validated at laboratory and pilot scale.
Typical applications include research and development, process design, feasibility studies, product development, and scale-up projects.
