Description

Continuous extraction tank for spice

Technical Field

The utility model relates to a natural perfume draws equipment, especially relates to a natural perfume's continuous extraction jar.

Background

The natural perfume has a long history of use in human activities, and ancient people use aromatic parts of animals and plants as raw materials to prepare original-state perfume materials through simple processing, and most of the shapes of the natural perfume materials keep some inherent appearance characteristics of the animals and plants, such as incense wood blocks, incense wood pieces, incense powder and the like; the aromatic substances separated from natural raw materials by physical methods (steam distillation, extraction, squeezing, etc.) in modern times are in the forms of essential oil, extract, absolute oil, balm, tincture, isolated natural perfume, etc., such as rose oil, vanilla tincture, jasmine extract, ylang essential oil, litsea cubeba oil, osmanthus absolute oil, menthol, etc. Conventional perfume extraction techniques include steam distillation, leaching and pressing, among others.

The steam distillation comprises various forms of water distillation, direct steam distillation, rotary cone stripping distillation and the like, and is suitable for extracting some natural perfumes with low aroma component boiling points, for example, the current high-quality rose essential oil is still extracted by using the steam distillation.

The extraction method is suitable for raw materials whose aroma components are easily deteriorated when heated, or some aroma components are dissolved in water and are not suitable for steam extraction. The most common is a volatile solvent extraction method, and the used solvent is petroleum ether, benzene, dichloroethane or a mixed solvent and the like; when carbon dioxide is used as a solvent, a supercritical extraction method can be adopted, the solvent is not required to be removed by heating at a lower temperature, the processing and extraction of food flavors are extremely suitable, the product fragrance is closer to natural raw materials, and no solvent residue exists. But the industrial application is not wide due to large equipment investment and higher technical requirement.

The squeezing method has wide application range, and is only suitable for extracting essential oil of citrus pericarp, such as sweet orange oil, lemon oil, shaddock oil, orange oil, etc.

The adsorption method is used as early as 18 th century, and is a method for absorbing aromatic components in fresh flowers by refined oil, replacing the flowers after a period of time, saturating the oil absorbing the aromatic components of the fresh flowers after replacing for many times, and then removing the aromatic components absorbed balsam by alcohol; at present, activated carbon, novel porous polymer and the like are mostly used as adsorbents, and then alcohol or supercritical carbon dioxide is used for desorption, so that the quality and the yield of essential oil are obviously improved.

The existing common extraction method mainly uses a medium or a solvent to carry out aroma components, and then concentrates or removes the solvent to obtain the aroma extract, so that the influence of the extraction process and the solvent on aroma is reduced as much as possible, and the aroma components in the natural aroma are completely and completely extracted.

However, these methods of extracting a perfume have disadvantages in extracting a perfume from a solid or viscous paste having a low water content, a strong fragrance, or a high boiling point of the fragrance component. Particularly, for some natural perfumes, the traditional production mode has limited yield and cannot meet the market demand. Therefore, it is desirable to design a way to rapidly produce perfume extracts in large quantities while ensuring the quality of the perfume extracts.
