Supercritical CO₂ fluid extraction stands as a versatile and efficient method for obtaining high-quality extracts in various industries. The functionality of a supercritical CO₂ fluid extraction device relies on the seamless integration of eight distinct parts. Each component plays a crucial role in ensuring the precision and success of the extraction process.

Functional Overview of Supercritical CO₂ Fluid Extraction Process Device

1. Refrigeration System

The refrigeration system serves as the cooling powerhouse of the extraction device, maintaining the CO₂ in a supercritical state. This is essential for achieving optimal extraction conditions. Through a careful balance of temperature control, the refrigeration system ensures that the CO₂ transitions seamlessly between liquid and supercritical phases.

2. Heating System

Complementing the refrigeration system, the heating system is responsible for elevating the temperature of the CO₂ to its supercritical state. Precision in temperature control is paramount, as deviations can impact the efficiency and specificity of the extraction process. The heating system is intricately linked with the refrigeration system to achieve the desired extraction conditions.

3. Pressurization System

The pressurization system works hand-in-hand with the refrigeration and heating systems to control the pressure within the extraction chamber. Maintaining the CO₂ at supercritical conditions requires a delicate interplay between temperature and pressure. The pressurization system ensures that the CO₂ remains within the desired range, optimizing the extraction efficiency.

4. Purification System

The purification system is the gatekeeper of extract quality. It is responsible for removing impurities and undesired components from the final product. By employing various filtration and separation techniques, the purification system guarantees the purity and potency of the extracted compounds.

Supercritical CO₂ Circulation System

CO₂ Circulation System

The CO₂ circulation system acts as the circulatory system of the extraction device. It ensures the continuous flow of supercritical CO₂ throughout the system, enabling a consistent and controlled extraction process. This system facilitates the transfer of CO₂ from the extraction chamber to the separation system and back, creating a closed-loop operation.

Core Systems Ensuring Device Functionality

  • Extraction System :The extraction system is the heart of the device, where the targeted components are extracted from the raw material. It involves the interaction of supercritical CO₂ with the feed material, allowing for the selective extraction of desired compounds. The efficiency of the extraction system is contingent on the precise coordination of temperature, pressure, and CO₂ flow rates.
  • Separation System :Working in tandem with the extraction system, the separation system is responsible for isolating the extracted components from the supercritical CO₂. Through controlled changes in temperature and pressure, the separation system allows for the collection of the desired compounds while leaving impurities behind.

Ensuring Precision Through Computer Control

Computer Control System

The computer control system acts as the central nervous system, orchestrating the coordination of all components. It ensures real-time monitoring and adjustment of parameters, allowing for precise control over the extraction process. The computer control system enhances the repeatability and reliability of the extraction device, contributing to consistent product quality.
