When choosing an extraction vessel for CO2 extraction equipment, it is important to consider the specific requirements of the extraction process, including the material being extracted and the desired output. In your case, where you are designing an extraction device to extract certain Chinese medicine ingredients, it is crucial to select an extraction vessel that can handle high pressure and is suitable for the specific form of material being extracted.
Based on the information you provided, it is recommended that you choose an extraction vessel with a maximum working pressure of at least 35 MPa to meet your requirements. It is also important to consider the design and construction of the vessel to ensure it can handle high pressure and is made of durable materials that can withstand repeated use.
Additionally, it is important to choose an extraction vessel that is suitable for the form of material being extracted. For solids, a hanging basket is typically used, while for liquids, a kettle with stainless steel ring packing may be necessary. Therefore, it is essential to select an extraction vessel that is appropriate for the specific material you are extracting.
Extraction vessel aspect ratio
Other important to consider the aspect ratio of the vessel. The aspect ratio refers to the ratio of the height to the diameter of the vessel and can have a significant impact on the efficiency and effectiveness of the extraction process.
- For solid materials, an aspect ratio between 1:4 and 1:5 is recommended. This aspect ratio allows for efficient loading and unloading of the material and ensures that the CO2 can penetrate and extract the material evenly.
- For liquid materials, an aspect ratio of around 1:10 is typically used. This aspect ratio allows for continuous extraction, where the liquid material is continuously fed into the vessel and the extracted material is continuously removed.
- It is important to note that the aspect ratio should be selected based on the specific material being extracted and the desired output. The aspect ratio can impact the yield and quality of the extracted material, as well as the overall efficiency of the extraction process.
When choosing an extraction vessel for supercritical CO2 extraction equipment, it is essential to consider the specific requirements of the extraction process, including pressure, material, and aspect ratio and select a vessel that is suitable for the specific material being extracted and the desired output.
