product Overview

The laboratory centrifugal extraction system is a multi-stage countercurrent continuous extraction experimental platform built by integrating multiple small-flow centrifugal extractors with a drum diameter of 50mm through pipelines and controls. The system simulates an industrial continuous production mode and can realize true countercurrent extraction in a laboratory environment. It is used to accurately determine key process data such as extraction stages and mass transfer efficiency, providing direct and reliable decision-making basis for industrial scale-up.

Features Introduction

1. Multi-stage countercurrent extraction: By flexibly connecting multiple single machines in series, reverse contact of two-phase liquid flows is achieved, the recovery rate and purity of the target product are greatly improved, and the industrial continuous process is fully simulated.

2. Highly integrated and automated: The system integrates feed pumps, control systems, electrical instruments, etc., which can achieve accurate control and stable operation of flow and speed. It has a high degree of operation automation and good data repeatability.

3. Small amplification effect: The core separation unit has the same principle as the industrial-grade centrifugal extractor. The experimental data is highly reliable and the process amplification risk is significantly reduced. It is a "bridge" connecting laboratory research and industrial production.

4. Flexible and scalable configuration: The series stages (such as stages 3, 5, 10, etc.) can be flexibly adjusted according to experimental needs to meet the needs of different process development stages from simple extraction to complex purification.

5. Safety and environmental protection: The system usually operates in a closed environment to effectively prevent the leakage of volatile, irritating or toxic reagents and ensure the safety of laboratory personnel and the laboratory environment.
