Embodiment 1

[0071] Embodiment 1, application method of the present invention and device extract Angelica sinensis

[0072] This embodiment takes the extraction of Angelica sinensis as an example. Since the Pharmacopoeia uses the content of ferulic acid in angelica as the evaluation standard, and ferulic acid is a fat-soluble substance, applying the method and equipment of the present invention and carrying out related control experiments can fully demonstrate that the method of the present invention can not only extract water-soluble and fat-soluble ingredients, and has a certain extraction rate, which improves the utilization rate of medicinal materials or plants.

[0073] Raw material: Angelica sinensis, the dried root of Angelica sinensis (Oliv.) Diels, an umbrella plant. The manufacturer of angelica in this experiment is Hualong Traditional Chinese Medicine Decoction Pieces Factory, the specification is decoction pieces, and the batch number is 200330621. Chinese angelica decoction ...

Embodiment 2

[0075] Embodiment 2, application method of the present invention and device extract Angelica sinensis

[0076] For the medicinal residues remaining in Example 1, add 15 kg of normal temperature aqueous solution to the extraction tank for the second extraction, keep the pressure at 30 MPa, increase the extraction temperature to 30° C., and extract for 1 hour to obtain the extract. It is a light orange-yellow and transparent emulsion with a specific gravity of 1.000. The liquid has no bitter taste, maintains the original fragrance of angelica, and has almost no precipitation. After being placed for 2 weeks, it still maintains the state of emulsion and no new precipitation. It shows that the extraction of angelica The performance of the liquid is very stable.

Embodiment 3

[0077] Embodiment 3, application method of the present invention extracts Angelica sinensis

[0078] Weigh 5 kg of Angelica sinensis coarse powder (the same batch as Angelica sinensis coarse powder in Example 1), soak for 12 hours at normal temperature, put into an extraction tank, then add approximately 15 kg of normal temperature aqueous solution, and the extraction conditions are as shown in Table 1.

[0079] work pressure

[0080] The obtained extract is a light orange-yellow and more transparent emulsion with a specific gravity of 1.002. The liquid has no bitterness, maintains the original fragrance of Angelica sinensis, and has almost no precipitation. After being placed for 2 weeks, it still maintains the emulsion state, and no new precipitation separates out. It shows that the performance of angelica extract is very stable.

Abstract

The invention discloses a kind of extraction method and device. The method includes following steps: crushing and immersing the materials, carries on extraction under pressure of 25MPa-35MPa and frequency between 18 KHz-33 KHz by using water as solvent, the extraction liquid with material active ingredients can be gotten. The invention can protect the biology activity, and it can realize nearly fully extraction of ingredients.

Description

technical field [0001] The invention relates to an extraction method and a device thereof, in particular to an extraction method and a device thereof using the principle of nonlinear vibration and critical extraction, which can be applied to the extraction of traditional Chinese medicines and plants. Background technique [0002] Chinese medicine is a traditional Chinese medicine, and it has a long history in China to prevent and treat diseases with Chinese medicine. The World Health Organization also recommends the use of traditional Chinese medicine to all countries, hoping that people can eat safe, efficient, quick-acting and convenient Chinese medicine. However, due to the relatively backward production process of traditional Chinese medicine, especially the extraction and separation process, it is difficult to achieve standardization and normalization of product quality control, and it has been difficult for Chinese medicine to be registered, legally sold and used in th...
