Description

Technical Field

[0001] The utility model relates to the technical field of extraction kettles, in particular to a supercritical point extraction kettle. Background Art

[0002] Supercritical extraction kettle is a kind of equipment specially used for supercritical fluid extraction technology. Supercritical fluid extraction technology is a new chemical process technology that combines extraction and separation. It uses CO2 in a supercritical state of multi-phase behavior as an extraction solvent to infiltrate and dissolve the material, and extract and separate the effective components.

[0003] When the existing extraction kettle uses the pressing method for supercritical point extraction, it usually adopts a single method to squeeze the material up and down for extraction. This method usually makes the material become more and more compact under the continuous squeezing action, which will have many effects on the extraction efficiency. First, the compaction of the material will hinder the effective penetration of the supercritical fluid (such as CO2). Since the diffusion coefficient of the fluid will decrease in the compact material, the opportunity for the fluid to contact the target component in the material is reduced, resulting in a decrease in the extraction rate and extraction efficiency. The compaction of the material may cause uneven distribution of the fluid in the material, thereby affecting the uniformity of the extraction. This means that the extraction degree of the target component in the material in different parts may be different, and the extraction quality of the final product may be affected. For this reason, we provide a supercritical point extraction kettle. Utility Model Content
