Abstract

The invention provides a 5L supercritical carbon dioxide extraction nanocrystal device. The device comprises a carbon dioxide steel cylinder, a purification and activation system connected to the carbon dioxide steel cylinder, a refrigeration system connected to the purification and activation system, a carbon dioxide liquid storage tank connected to the refrigeration system, a high-pressure pump connected to the carbon dioxide liquid storage tank, a carrying agent pump connected to the high-pressure pump, a mixer connected to the high-pressure pump and the carrying agent pump simultaneously, a pre-heater connected to the mixer, a 5 L extraction kettle connected to the pre-heater, and an extract crystallizer used for separating extract and CO2 fluid, wherein the lower part of the extract crystallizer is connected to a filtered material receiver and is also connected to a flow meter; the flow meter is connected to the carbon dioxide steel cylinder. The 5 L supercritical carbon dioxide extraction nanocrystal device is used for extracting nanocrystals.

Description

technical field [0001] The invention relates to a 5L supercritical carbon dioxide extraction nanocrystal device, which belongs to the technical field of extraction. Background technique [0002] The supercritical fluid extraction separation process is carried out by using the relationship between the dissolving ability of supercritical fluid and its density, that is, utilizing the influence of pressure and temperature on the dissolving ability of supercritical fluid. When the gas is in a supercritical state, it becomes a single phase state between liquid and gas, with a density close to that of liquid, although its viscosity is higher than that of gas but significantly lower than that of liquid, and its diffusion coefficient is 10 to 100 times that of liquid; Therefore, it has good permeability and strong dissolving ability to the material, and can extract some components in the material. [0003] Due to the low critical temperature and critical pressure of CO2 gas (3...
