Method for extracting fragrant liquor and essential oil from aromatic plants by dry-process

Abstract

The present invention discloses a dry method for refining balsam and essential oil from aromatic plants, aromatic plants are refined and put in a device, a heating chamber (4) is connected with an evaporating chamber (1) through a pipeline, the evaporating chamber (1) is connected with an extraction chamber (2) through a pipeline, the extraction chamber (2) is connected with a blower (3) through a pipeline, the blower (3) is connected with the heating chamber (4) through a pipeline, and a sealed circulation loop device is formed. The hot blast temperature is controlled between 60 DEG C and 90 DEG C, the wind speed is controlled at 1 meter to 15 meters per minutes, the inlet temperature of a condensing reed pipe (23) is 3 DEG C to 25 DEG C, and balsam and essential oil can be collected in a discharge pipe(24). In the present invention, no water, special gas and organic solvent are added into raw material, balsam and essential oil which are refined are uncorrupt in smell, small in equipment volume, simply in art, high in efficiency, low in energy consumption, simply in operation and high in production efficiency; no pollution material is discharged, no cooking water and steam are consumed, balsam after being refined can be used as additive of food, drink and condiment, and used for hairdressing, face-painting, bath, and health care, in addition, the aromatic plants after being refined balsam and essential oil is in the dry shape and reserved in a whole, then can be used sequentially, thereby saving resources.

Description

Technical field [0001] The invention relates to a method for extracting aromatic extracts from aromatic plants, in particular to a dry method for extracting aromatic liquid and essential oil from aromatic plants. Background technique [0002] At present, there are generally three methods of extracting essential oils from aromatic plants in the world, such as extracting rose essential oil from roses: the first is the "water boiling method". Proportion of water, the bottom of the kettle is heated by steam until the water in the kettle boils, the aromatic substances in the flowers evaporate together with the water vapor, and are guided into the condenser by the pipe to cool, and the cooling liquid flows into the oil-water separator. According to the different specific gravity of oil and water, Separate rose essential oil and rose water. The main problem of the water boiling method is that the long-term high-temperature cooking makes the aromatic alcohol esters of roses mutate,...

AI Technical Summary

Problems solved by technology

The main problem of the water boiling method is that the long-term high-temperature cooking makes the aromatic alcohol esters of roses mutate, and the extracted essential oils do not have the natural aroma of flowers, but are strong and pungent, and the smell is impure. During the production process, A lot of equipment, high energy consumption, many operators, low efficiency, large amount of residual liquid and residue pollution, and consume a lot of steam and cooling water; the second is "solvent extraction method", using organic solvents, such as alcohol, ether or liquid Butane, etc., repeatedly sprinkle organic solvents on fresh roses, dissolve the aromatic substances in the flowers into the solvent, and then use low-temperature distillation to extract the aromatic substances in roses

The main problems of the solvent extraction method are that the equipment and process are complicated, and steam and cooling water are also consumed. Due to the use of organic solvents, the investment is large, the output is low, and it is easy to pollute the essential oil, the oil yield is low, and the separated essential oil is not Pure; the third is "carbon dioxide supercritical extraction method", the extraction process is to use CO 2 In a low-temperature critical environment, the aromatic substances in roses are extracted. This process adapts to the low-temperature aromatic characteristics of roses. The extracted essential oils have pure fragrance and are very similar to flowers.

The main problem of carbon dioxide supercritical extraction method is that the equipment and process are very complicated, the processing capacity is low, the equipment investment is expensive, and there is also waste residue discharge to pollute the environment. At present, this method is only in the laboratory stage, and there is no precedent for mass production of enterprises using this method.

[0003] Before the completion of the present invention, it has not been seen that the same dry method as the present invention extracts aromatic liquid and essential oil from aromatic plants to be used in people's daily life. The aromatic liquid and the essential oil extracted by the dry method of extracting aromatic liquid and essential oil from aromatic plants are sold on the market, and there is no dry method identical with the present invention to extract aromatic liquid and essential oil from aromatic plants and The aromatic liquid and essential oil extracted from it have been recorded in the literature
