Abstract

The invention belongs to the technical field of superfluid extraction and particularly relates to a supercritical CO2 fluid extraction kettle and an extraction method thereof. The supercritical CO2 fluid extraction kettle comprises a box body, a supporting frame and gas supply equipment; the gas supply equipment is used for intermittently introducing carbon dioxide into the box body; feeding portsfor introducing process mediums are formed in the two sides of the top of the box body; a gas inlet for introducing the carbon dioxide is formed in the middle part of the top of the box body; a discharging port is formed at the bottom of the box body; the part below the gas inlet is fixedly connected with a U-shaped groove; through holes are formed in the two sides of the U-shaped groove; the gassupply equipment is communicated with the U-shaped groove through the gas inlet; a T-shaped rod is arranged in the U-shaped groove; the T-shaped is connected with the U-shaped groove through a spring; and one end of the T-shaped rod is fixedly connected with a screw rod after stretching out of the U-shaped groove. The supercritical CO2 fluid extraction kettle is simple in structure and convenientto operate; through a stirring unit, the extraction efficiency of the process mediums is improved; furthermore, through cooperation with a gear rack and a gas bag during work of the stirring unit, the extraction efficiency of the process mediums can be further improved.

Description

technical field [0001] The invention belongs to the technical field of superfluid extraction, in particular to a supercritical CO2 fluid extraction kettle and an extraction method. Background technique [0002] Supercritical is a supercritical fluid, which is a state of matter that is neither gaseous nor liquid between gas and liquid. This substance can only exist when its temperature and pressure exceed the critical point. The density of supercritical fluid is relatively high. Large, similar to liquid, and its viscosity is closer to gas, so supercritical fluid is a very ideal extraction agent. [0003] Superfluid extraction can extract process media such as Chinese herbal medicines to improve the purity of the process medium, and the extraction needs to be operated in an extraction kettle. The existing extraction kettle is bulky, complicated to operate, low in extraction efficiency, and the purity of the obtained process medium is low. At the same time, there is a lack of ...
