Abstract

The invention discloses an industrial supercritical CO2 extraction system, and belongs to the field of industrial supercritical CO2 extraction technology. The system comprises an extraction kettle which is connected to a feed pipe, the extraction kettle is connected to a residue discharging pipe, and the extraction kettle is connected to a high pressure filter and a first stage separation preheater; the first stage separation preheater is connected to a first stage separation kettle, the first stage separation kettle is connected to a first stage product tank, and the first stage product tank is connected to a product storage tank by a number one product pump. The extraction operation is completed by simple equipment and processes, and production cost is reduced; CO2 is used as a solvent, supercritical state of CO2 is easy to realize, CO2 does not have toxic pollution problems for foodstuffs and medicines, and CO2 can prevent bacterial activity; CO2 is inert gas and is not easy to combust, and CO2 has stable chemical performance and low price with economical efficiency.

Description

technical field [0001] The present invention relates to industrialized supercritical CO 2 Extraction technology. Background technique [0002] In the production and preparation of food and medicine, it is necessary to extract the required substances from some liquid solvents, especially in the extraction and separation of sea buckthorn oil, decaffeination of coffee beans, nicotine of tobacco, and non-flavored Extraction, the extraction of useful components in hops, the extraction of soybean oil and egg yolk from soybeans, due to the high requirements for various temperatures and pressures during the extraction process, and the products obtained during the extraction process are likely to be thermally decomposed, and after The solvent after extraction is usually discharged directly, causing pollution to the environment; at the same time, in the actual production and preparation process, the requirements for the required equipment are relatively high, and the production syste...
