Problems solved by technology

[0004] Extracting zedoary oil from zedoary. At present, all domestic production enterprises use the traditional steam method and workshop-style production. The disadvantage of this method is that the cooking temperature is greater than 100°C and the extraction time is long. It takes 24 hours to complete each batch of production. low rate

Embodiment Construction

[0017] The following is a detailed description of the invention.

[0018] In extraction tower 5 or extraction tower 6, add the curcuma powder 1500 kilograms of average particle diameter 2mm. open or close figure 1 The corresponding valve in the process, the CO 2 CO in storage tank 1 2 The fluid is released, flows into the plunger pump 4 after passing through the filter 2 to pressurize, then increases the temperature through the heat exchanger 7, and enters the extraction tower from the lower part of the extraction tower 5 or the extraction tower 6, and the CO 2 After the fluid dissolves the zedoary oil, it flows out from the upper part of the extraction tower to the separator A from the bottom to the top. After part of the zedoary oil is separated out in the separator A, it flows out from the top to the separator B, and the dissolved zedoary oil is separated out in the separator B. CO 2 The fluid flows out from the upper part of the separator B, is refrigerated and cooled,...

Abstract

The invention relates to an industrial production method for extracting zedoary turmeric oil from zedoary turmeric by adopting a supercritical CO2 fluid. The zedoary turmeric oil containing multiple kinds of antitumor components is extracted from zedoary turmeric powder under a supercritical state by utilizing a carbon dioxide fluid, the extraction temperature is 40-60 DEG C, the extraction pressure is 15-22 MPa, and the extraction time is 4-8h, and the extraction ratio of the zedoary turmeric oil is 4.3 percent. The zedoary turmeric oil comprises the following antitumor active components in percent by weight: 3.8 percent of elemene sum, 6.9 percent of Germacrone, 19 percent of curzerene and 2 percent of curcumenol.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to supercritical CO 2 Extraction and separation process. Background technique [0002] Supercritical CO 2 The extraction process is a new process developed in the 1980s. Many countries in the world have been widely used in food and extracting organic matter from plants and other fields. In China, supercritical CO 2 Extraction techniques are widely used in the field of laboratory research on a small scale. [0003] The zedoary oil extracted from zedoary is a kind of traditional Chinese medicine. Various injections of zedoary oil have been widely used clinically. It is an achievement made by the Chinese medical circle for 30 years. The zedoary oil glucose injection is the 1995 edition of "Chinese Pharmacopoeia" Two newly recorded antiviral drugs. The traditional Chinese medicine theory of zedoary oil believes that zedoary is pungent, bitter, warm, and returns to the liver and splee...
