Referring to fig. 3, the natural animal and plant extraction method according to an embodiment of the present invention may adopt the natural animal and plant extraction system 10, and the natural animal and plant extraction method includes the following steps:

S1001: and a pretreatment step, namely pretreating and crushing natural animal and plant raw materials to be extracted.

The natural animal and plant to be extracted can be various natural plants and fruits thereof, single/compound traditional Chinese medicinal materials and other dried products, and can also be various animal tissues and organs and other dried products.

In one embodiment, the natural animal and plant to be extracted is one or more of ganoderma lucidum, rose, medlar, dried orange peel and almond.

In one embodiment, the natural animal and plant to be extracted is Ganoderma lucidum.

The ganoderma lucidum has the function of bidirectionally regulating the human body function, and can regulate the balance of the human body function in a bidirectional way on the whole, so that the immune system of a human body is comprehensively and rapidly promoted, and the viscera and cells of the human body are recovered to reach the standardization. Mainly has the effects of resisting tumor and aging and preventing and treating nervous system diseases.

The step can adopt dry grinding, ultramicro grinding, low-temperature grinding, wet grinding and other methods.

In one embodiment, the natural animals and plants are pulverized to a particle size of 20-60 mesh. The natural animal and plant powder in the particle size range has appropriate specific surface area, and ensures supercritical CO₂The fluid and the material have a faster mass transfer rate, and further higher oil yield and quality are ensured.

S1002: the first extraction step, namely, carrying out first extraction on the natural animals and plants after pretreatment by using a supercritical carbon dioxide extraction method, and separating components dissolved in the supercritical carbon dioxide to obtain a first extraction component of the natural animals and plants.

in S1002, the above-described carbon dioxide supercritical extraction apparatus may be used, or an existing apparatus may be used.

The physical and chemical properties of the supercritical carbon dioxide are greatly different from those of liquid and gas in a non-critical state, the viscosity of the supercritical carbon dioxide is one percent of that of the liquid, and the natural diffusion coefficient of the supercritical carbon dioxide is 100 times that of the liquid, so that the supercritical carbon dioxide has good mass transfer characteristics and can greatly shorten the time required by phase equilibrium. In the vicinity of the critical point, a small change in pressure and temperature causes a great change in density of carbon dioxide, so that the dissolving capacity of carbon dioxide can be adjusted by changing the pressure and temperature thereof to improve the selectivity of extraction, and because of this, the pressure and temperature of carbon dioxide need to be strictly controlled to improve the extraction rate when extraction is performed.

In one embodiment, the extraction conditions of the first extraction are: the pressure of the extraction kettle is 15-30 Mpa, the temperature is 20-25 ℃, the conveying flow of supercritical carbon dioxide is 10-60L/h, and the extraction time is 1-5 h. Under the extraction condition, the method has better extraction efficiency.

In one embodiment, the separation conditions under which the first extracted component is separated are: the pressure of the separation kettle is 5-15Mpa, and the temperature of the separation kettle is 25-25 ℃.

The fat-soluble component of the natural animal and plant to be extracted, namely the first extraction component, can be obtained by the step.

S1003: and a second extraction step, mixing the dregs of a decoction and the extraction solvent in the first extraction step, and performing second extraction by using a high pressure difference low-temperature extraction method to obtain a natural animal and plant extracting solution.

It should be noted that the above-mentioned high-pressure-difference continuous extraction separation unit may be adopted, or an existing apparatus may be adopted.

In one embodiment, the high pressure difference continuous extraction and separation unit adopts a continuous extraction and separation concentrator described in patent No. cn200920302058. x.

The high pressure difference extraction method is to provide certain pressure for tissue cells, and the extraction solvent is pushed by the high pressure to break the plant cells, so that the effective components in the raw materials are dissolved in the corresponding solvent. Therefore, the method can extract and separate the water-soluble components in the natural animals and plants by only selecting a proper water-soluble solvent. The method has high extraction rate and less restriction on solvent selection. Maintaining at a predetermined pressure for a period of time to allow the effective components to reach a dissolution equilibrium and then rapidly release the pressure, and allowing the effective components to rapidly diffuse into the extraction solvent around the tissue under the action of the osmotic pressure outside the cells. Since the high-pressure extraction is a process in which pressure is instantaneously transferred by the action of a liquid medium, the extraction can be subjected to uniform pressure action regardless of whether liquid or solid is extracted. And under such pressure, only non-covalent bonds are affected, but covalent bonds are not affected, and thus active components are not damaged.

In one embodiment, the extraction conditions for the second extraction are: the pressure is 30MPa to 50MPa, and the temperature is 10 ℃ to 90 ℃.

The extraction solvent used is selected according to the nature of the natural animal or plant to be extracted, and can be water or 20-80% ethanol water solution by volume fraction.

In addition, in order to ensure the extraction rate, the weight ratio of the extraction solvent to the natural animals and plants also needs to be controlled. In one embodiment, the ratio of the mass of the natural animal and plant corresponding to the herb residue to the mass of the extraction solvent is 1 (10-80). Within this range, on the one hand, the extraction rate of the extraction step can be ensured, and on the other hand, the cost can be controlled.

S1002: and a filtering step, namely filtering the natural animal and plant extracting solution to obtain natural animal and plant clear solution.

the step is mainly to separate and purify the extracting solution so as to improve the purity of the second extracting component.

In one embodiment, the natural animals and plants are centrifuged, then membrane filtration is performed, preliminary purification can be performed through centrifugation, substances such as resin, tannin, heavy metals and the like can be removed through membrane separation, and the purity and the taste of the obtained extract are greatly improved.

S1005: and a concentration step, namely concentrating the natural animal and plant clear liquid to obtain a second extraction component.

wherein the concentration may be vacuum concentration or reverse osmosis concentration. The concentrated liquid can also be dried by vacuum drying, boiling drying or spray drying.

It should be noted that, the auxiliary materials can be added before drying after concentration to meet the requirement of practical application, and the category of the auxiliary materials can be any existing auxiliary materials, for example: stabilizer, solubilizer, disintegrating agent, aromatic, correctant, antiseptic, etc.

The carbon dioxide supercritical extraction method in the method has good dissolving capacity for hydrocarbons and weak water-soluble fat-soluble substances, and has poor solubility for strong water-soluble compounds such as alkaloid and polysaccharide, so the method cannot extract the strong water-soluble components. Although the extraction rate of water-soluble components can be enhanced by adding an entrainer into solute and supercritical carbon dioxide, a large number of experiments show that the addition of the entrainer can cause complex changes of phase behavior and solvent properties, so that the extraction conditions are difficult to control, the addition amount of the entrainer needs to be strictly controlled, and the extraction rate is greatly influenced by too much or too little addition amount of the entrainer. In addition, a solvent miscible with the supercritical fluid needs to be selected as the entrainer, so the selection range of the solvent is limited. The use of entrainer also causes solvent residue, which increases the trouble of recovering entrainer by subsequent extraction and separation.

The method extracts the water-soluble components and the fat-soluble components separately, effectively avoids the problem of using a solvent (entrainer) in the supercritical carbon dioxide extraction, ensures that the extraction conditions of the supercritical carbon dioxide are easy to control, and improves the extraction rate of the fat-soluble components; and because the fat-soluble components are extracted and separated by the carbon dioxide supercritical extraction method, when the water-soluble components in the residual residues are extracted by adding the extraction solvent, the mass transfer resistance of the solvent is reduced, the solvent is better diffused into cells, and the extraction rate of the water-soluble components is further improved. Therefore, the two-step extraction method of the method supplements each other, so that the extraction rate of the first extraction component and the second extraction component is obviously improved, and efficient, comprehensive and continuous extraction is realized.

In addition, the temperature of each step in the natural animal and plant extraction method is low, so that the decomposition of active components can be effectively prevented, the natural animals and plants can be prevented from mildewing, the first extraction step and the second extraction step can comprehensively sterilize the natural animals and plants, the whole extraction system is in an aseptic state, the occurrence of mildewing and the like is further effectively avoided, and the method has the advantages of low sterilization temperature, no residue, no pollution, less nutrient loss, high safety and the like, and the extracted natural animal and plant extract has high safety.

in conclusion, the natural animal and plant extraction method realizes efficient continuous production, so that the method can reduce public energy consumption and reduce the discharge of wastes, is simple and convenient to operate, has no special technical requirements, has higher economical efficiency, and is suitable for industrial production due to higher quality of the obtained product.

The present invention will be described in detail below with reference to specific examples.

in each of examples 1 to 2, the extraction was performed by using the natural animal and plant extraction system.
