Problems solved by technology
[0003] At present, the extraction methods used to extract curcumin from turmeric at home and abroad are: natural fermentation method, dilute hydrochloric acid hydrolysis method, and solvent gasoline extraction method. The extraction rate and benefit of methods such as turmeric ethanol warm extraction and turmeric ethanol percolation extraction are low. Because turmeric is rich in protein, it is difficult to operate during the extraction process; therefore, it is difficult to operate in a factory

Embodiment Construction
[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.
[0025] Such as figure 1 , 2 , as shown in 3,
[0026] The turmeric material transported from the system enters the storage bin 8, and the crushed turmeric material enters the extractor 6 evenly by controlling the flow rate of the air lock. The extractor 6 is connected with the mixed liquid heater 1 and the methanol circulation pump 2, and the methanol solution is transported to the extractor 6 through the methanol delivery pump, so that the methanol mixed solution and the fresh methanol solution are continuously circulated to soak the turmeric material.
[0027] The curcumin mixed solution extracted by the extractor 6 of the present invention is filtered by the mixed solution filter 7 and then sent to the settling tank 15. After filtering, the mixed solution containing s...

Abstract
The present invention discloses an efficient curcumin extraction system. According to the present invention, the curcumin contained in broken dioscorea zingiberensis can be dissolved out by a methanolsolution; the boiling point of methanol is about 64.8 DEG C, and the environment of the whole system can be in the vacuum state through the vacuum device arranged in the system, such that the boilingpoint of methanol can be reduced to the lower temperature; by arranging a material leaching system, a material residue conveying system, a solvent separation system, a steam stripping system and a mixing liquid conveying system, dioscorea zingiberensis is repeatedly soaking in a leaching device with a fresh methanol solvent, such that the curcumin can be quickly and efficiently separated from thedioscorea zingiberensis, and the extraction rate is substantially increased; with the system of the present invention, the problem that the curcumin is difficult to separate due to the high starch content in the dioscorea zingiberensis is solved, and the curcumin can be continuously extracted from the dioscorea zingiberensis by the system; and by using the vacuum condensing system and the inclined plate steam stripping system, the loss of the methanol solvent is further reduced so as to reduce the generation of the system operation explosion factor while improve the solvent recovery rate, theeconomic benefits and the market competitiveness.
Description
Technical field: [0001] The technology involved in the invention is applied to the technical field of extracting curcumin, a medical raw material for anti-oxidation, anti-inflammation, anti-coagulation, lipid-lowering, anti-atherosclerosis, anti-aging, eliminating free radicals and inhibiting tumor growth, etc. from the Chinese medicinal material turmeric. Background technique: [0002] Curcumin is a pigment extracted from ginger, a plant of the Zingiberaceae family. Modern research has found that curcumin can inhibit inflammation, anti-oxidation, and anti-rheumatoid effects; American VITY Vitamin Magazine reported: "The main pharmacological effects of curcumin are anti-oxidation. , anti-inflammatory, anticoagulant, lipid-lowering, anti-atherosclerosis, anti-aging, eliminating free radicals and inhibiting tumor growth, etc. In November 2006, an article in the journal "Arthritis and Rheumatism" in the United States pointed out that curcumin can prevent Arthromegaly, arthritis...
