CO2 Extractor Technical Specifications CO2 Supercritical Extraction Machine

Understanding the technical specifications of CO2 supercritical extraction machines is essential for making an informed purchasing decision. This article breaks down the critical specifications, explaining their significance and providing examples of how they impact performance.

1. Capacity

The capacity of a CO2 extractor refers to the volume of raw material it can process per cycle. It is typically measured in liters.

• Small Scale: 10-20 liters, suitable for research and small-scale production.

• Medium Scale: 50-100 liters, ideal for small to medium-sized businesses.

• Large Scale: 200 liters and above, used for industrial operations.

Example: A 50-liter extractor is often used in the cosmetic industry to produce essential oils, handling around 15 kg of raw material per batch.

2. Pressure Range

The pressure range determines the machine's ability to operate in supercritical conditions. Most CO2 extractors operate between 70 and 350 bar.

• Standard Models: Up to 300 bar, suitable for general applications.

• High-Pressure Models: Up to 500 bar, used for specialized extractions like pharmaceutical-grade compounds.

In a case study, a high-pressure CO2 extractor yielded 98% pure omega-3 fatty acids at 350 bar, outperforming standard models.

3. Temperature Range

Temperature control is critical for targeting specific compounds without degradation. CO2 extractors typically operate between 31°C and 80°C.

• Low Temperatures: Ideal for heat-sensitive compounds like terpenes.

• Higher Temperatures: Used for more robust compounds, such as plant waxes.

An essential oil producer found that operating at 40°C preserved the aromatic profile of lavender oil more effectively than at higher temperatures.

4. Flow Rate

The CO2 flow rate, measured in kilograms per hour (kg/h), impacts the speed and efficiency of the extraction process.

• Low Flow Rates: Suitable for precise extractions, typically 5-10 kg/h.

• High Flow Rates: Faster processing for industrial-scale production, exceeding 50 kg/h.

For example, a 20 kg/h flow rate achieved a 20% faster extraction of cannabinoids compared to a 10 kg/h system.

5. Material and Build Quality

The machine's construction material impacts durability and compliance with industry standards:

• Stainless Steel: Commonly used for its corrosion resistance and durability.

• Food-Grade Materials: Required for edible product applications.

A pharmaceutical company reported a 15% reduction in maintenance costs after switching to a stainless steel CO2 extractor.

6. Automation and Control

Modern CO2 extractors often include automated controls for:

• Pressure and Temperature Regulation: Real-time adjustments for optimal extraction.

• Data Logging: Tracks parameters for consistency and analysis.

In a recent trial, automation reduced operator error by 30%, improving overall yield.

7. Safety Features

Safety is paramount in high-pressure systems. Key features include:

• Pressure Relief Valves: Prevent over-pressurization.

• Emergency Stop Functions: Immediate shutdown in case of anomalies.

Conclusion

By understanding the technical specifications of CO2 supercritical extraction machines, businesses can select the model that best suits their production needs. Consider factors like capacity, pressure, and automation to ensure optimal performance.
