Problems solved by technology

The Chinese fir essential oil extracted by the steam method has a pure aroma, which basically meets the requirements of fragrance blending, but the yield is very low; the solvent method extracts the Chinese fir essential oil with a higher yield than water vapor, but requires a large amount of solvent, the follow-up treatment is complicated, and there is high energy consumption. , the problem of solvent residues; the dry distillation method has a high extraction rate, and products such as wood vinegar, charcoal, wood tar and combustible gas can be obtained at the same time, but the dry distillation oil contains a large amount of tar, phenol, aldehydes and ketones, etc., which seriously affects the fir oil. The quality of crude distilled oil must be de-coke and deodorized in order to basically meet the requirements of flavoring

preparation example Construction

[0019] The invention provides a kind of preparation method of Chinese fir essential oil, and the method comprises the following steps:

[0020] (1) Grinding the Chinese fir raw material into powder, adding a surfactant, stirring and putting it into a distillation tower, then feeding water vapor into the distillation tower for distillation to obtain mixed steam;

[0021] (2) sending the mixed steam obtained in step (1) into a cooling tower for cooling treatment to obtain an oil-water mixed liquid;

[0022] (3) The oil-water mixed liquid in step (2) is subjected to rectification treatment, and the rectified Chinese fir essential oil is collected.

[0023] The inventor of the present invention found in the process of research that when the surfactant solution reached a certain concentration, it tended to form microclusters in water, the hydrophilic part faced outwards, and the hydrophobic part gathered in the center. When stirring fir powder and In surfactant solution, Chinese f...

Embodiment 1

[0030] This embodiment is used to illustrate the preparation method of Chinese fir essential oil of the present invention and its products.

[0031] Grind 10kg of Chinese fir raw material into 60-mesh powder with a pulverizer, add 200g of ethanol, stir well and put it into the distillation tower, pass 160°C water vapor into the distillation tower for 6 hours for distillation treatment to obtain mixed steam , and then the mixed steam is sent to the cooling tower for cooling treatment to obtain the oil-water mixed liquid, the oil-water mixed liquid is subjected to rectification treatment, and the distilled Chinese fir essential oil is collected.

Embodiment 2

[0033] This embodiment is used to illustrate the preparation method of Chinese fir essential oil of the present invention and its products.

[0034] Grind 10kg of Chinese fir raw material into the target powder with a pulverizer, add 300g of ethanol, stir well and put it into the distillation tower, pass 200°C water vapor into the distillation tower for 8 hours for distillation treatment to obtain mixed steam, Then the mixed steam is sent to the cooling tower for cooling treatment to obtain the oil-water mixed liquid, the oil-water mixed liquid is subjected to rectification treatment, and the distilled Chinese fir essential oil is collected.

Abstract

The invention discloses a preparation method of cedarwood essential oil. The method comprises the following steps: (1), grinding cedarwood raw materials into powder; adding surfactant into the powder;then performing stirring and dropping into a distilled tower, and then introducing water vapor into the distilled tower and carrying out distillation treatment to obtain mixed steam; (2), feeding themixed steam obtained in the step (1) into a cooling tower and carrying out cooling treatment to obtain oil-water mixed liquid; (3) performing refined distillation treatment on the oil-water mixed liquid obtained in the step (2) and collecting the cedarwood essential oil subjected to refined distillation. On the other hand, the invention also provides the cedarwood essential oil prepared by usingthe method. The preparation method of the cedarwood essential oil disclosed by the invention has the advantages that an operation is simple, the cost is low, the oil yield of the cedarwood raw material is high, and the preparation method of the cedarwood essential oil is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of essential oil extraction, and in particular relates to a preparation method of Chinese fir essential oil and a product thereof. Background technique [0002] Chinese fir is the most important tree species for afforestation in southern my country. The area of ​​Chinese fir forest has exceeded 9.11 million hectares, and the stock volume has exceeded 343 million m 3 . Chinese fir contains a large amount of Chinese fir essential oil, the main components of which are cedaryl alcohol, α-cedryne, β-cedryne, phoenixene, α-pinene, and α-terpineol. It is very close to cedarwood oil, so it can be used to replace cedarwood essential oil in the fragrance industry. Cedar wood oil has a strong woody-musk-ambergris aroma. It is mainly used in powder cosmetics and soaps such as talcum powder, pressed powder, rouge, etc., and can also be used in fantasy essences. Cedarwood oil is one of the top ten essential oils in the...
