Description

Technical Field

[0001] The invention relates to the field of Chinese medicine preparation, and in particular to a Chinese herbal medicine extract preparation device and a preparation method thereof. Background Art

[0002] The extraction of Chinese herbal medicine refers to the process of extracting effective ingredients from Chinese medicinal materials using appropriate solvents and methods. The extraction process is a solid-liquid extraction process, which mainly includes the following aspects: infiltration and penetration: the solvent adheres to the surface of the medicinal material and moistens it, and then penetrates into the cells; desorption and dissolution: the solvent desorbs the effective ingredients in the medicinal material from the tissue and dissolves them in the solvent; diffusion: the dissolved components diffuse from the cell to the surrounding solvent depending on the concentration difference; the extraction methods include immersion method: soaking the medicinal material in an appropriate solvent at room temperature or warm conditions for a certain period of time to extract the effective ingredients. It is suitable for sticky medicinal materials, medicinal materials without tissue structure, fresh and easy to swell medicinal materials, etc., but the extraction efficiency is low and the time is long; percolation method: the medicinal material powder is placed in a percolator, and the solvent is added to the powder to make it permeate through the powder and the extract flows out from the bottom.

[0003] When Chinese herbal medicines are processed by the immersion method, the existing screening components generally use manual methods to clean and collect the residues after enzymatic immersion and perform subsequent operations, which is not convenient for mechanical process discharge for further extraction. Moreover, if the residues containing liquid are pumped by a water pump, the finely divided residues will adhere to the moving parts of the pump body, which will affect the pump body over time. Summary of the invention

[0021] A method for preparing a Chinese herbal medicine extract, which is applicable to the above-mentioned Chinese herbal medicine extract preparation device, comprises the following steps:

[0022] S1, after the Chinese herbal medicine is chopped, it is put into the enzymatic hydrolysis barrel from the first feeding hopper, and the compound enzyme is used for enzymatic hydrolysis. The compound enzyme can be specifically selected as cellulase. The liquid ratio of Chinese herbal medicine to water is about 1:10, and the dosage of the compound enzyme is selected to be 1.0-1.5%. The filtrate is transferred to the mixing and screening barrel, and the liquid filter residue is transferred to the ethanol extraction barrel;

[0023] S2: Add 75% ethanol solution from the second feeding hopper, extract for 2 hours, separate the further extract and filter residue again, sieve with a mesh size of 60, transfer the extract to the mixed sieving bucket, and transfer the liquid-containing filter residue to the water extraction bucket;

[0024] S3: Add clean water from the third feeding hopper, the ratio of extract to clean water is 1:5, and the extraction takes 4 hours. During this period, an additional heating component is wrapped on the barrel body of the water extraction barrel for heating at 50 degrees Celsius. The filter residue is directly discharged, and further extract is sent to the mixed screening barrel with a screening mesh of 80 mesh. Finally, the preparation of the Chinese herbal medicine extract is completed.

[0025] The invention provides a Chinese herbal medicine extract preparation device and a preparation method thereof, and its beneficial effects include:

[0026] 1. By setting a lifting component and combining it with a stirring mechanism with adjustable blade angles, after the stirring and enzymolysis is completed, the screen of the lifting component can directly press the enzymolysis liquid downward, so that the drug residue is at the bottom and the drug liquid is at the top. The drug residue will naturally fall into the pipeline under the action of gravity and proceed to the next step of operation, which solves the problem that the filtered drug residue is not convenient to collect for subsequent operations in the common screening method. Through the stirring mechanism with adjustable angle combined with the lifting component, the drug residue and the drug liquid can be quickly separated after the stirring and enzymolysis is completed, which greatly shortens the time required for the traditional screening method and improves the speed of the overall production process. The drug residue can naturally fall into the pipeline under the action of gravity for the next step of operation, without the need for additional manual intervention to transfer the drug residue, thereby achieving the continuity of the production process and reducing the time wasted due to operation interruptions.

[0027] 2. By setting a hose, the working part of the pump body where the hose is located, namely the triangular plate and the outer ring of the roller are located outside the hose, and the roller used for extrusion has no contact with the liquid-containing filter residue at all, thereby preventing the drug residue from adhering to the active part of the pump body. The pump used to move the drug residue will not have working obstacles caused by the blockage and adhesion of the drug residue. Since the roller has no contact with the liquid-containing filter residue at all, the drug residue is prevented from adhering to the active part of the pump body, which greatly reduces the risk of equipment failure caused by the blockage and adhesion of the drug residue, so that the pump can work continuously and stably, reduces production interruptions caused by equipment failure, and improves production efficiency. Without the interference of drug residue, the pump can more accurately control the conveying volume and speed of the drug residue to ensure that the drug residue can be processed in the next step according to the predetermined process.

[0028] 3. By setting a closing mechanism, when the liquid-containing drug residue enters the steps of ethanol extraction and water extraction, the pipe used to deliver the liquid-containing drug residue will first pass through the movable fan-shaped baffle of the closing mechanism, and the screen where the closing mechanism is located will move downward under the action of the lifting mechanism and will be closed under the action of the torsion spring, so that after the liquid-containing drug residue is injected, it will enter the lower part of the screen, the drug residue is at the bottom, and the drug liquid is at the top. The drug residue will naturally fall to the pipeline under the action of gravity and proceed to the next step. At the same time, the filter element of the screening mechanism is vertically arranged, and the liquid filter residue will first flow out from the lower section of the filter element. After being used for a long time, the lower section will be relatively blocked, and the liquid level will rise. The raised liquid level will contact the new unblocked part of the filter element. Generally speaking, the filtration of the liquid always has a filtration part with intact permeability, which solves the problem that the existing filter screen is fully in contact with the liquid for filtration from the beginning, and the filtration effect tends to decline from the beginning.

By arranging the hose 610, the working part of the pump body 6 where the hose 610 is located, namely the triangular plate 608 and the outer circle of the roller 6082 are located outside the hose 610, and the roller 6082 used for extrusion has no contact with the liquid-containing filter residue at all, so as to prevent the drug residue from adhering to the active part of the pump body 6. The pump used to move the drug residue will not have any working obstacles caused by the blockage and adhesion of the drug residue. Since the roller 6082 has no contact with the liquid-containing filter residue at all, the drug residue is prevented from adhering to the active part of the pump body 6, which greatly reduces the risk of equipment failure caused by the blockage and adhesion of the drug residue, so that the pump can work continuously and stably, reduces production interruptions caused by equipment failure, and improves production efficiency. Without the interference of the drug residue, the pump can more accurately control the conveying amount and speed of the drug residue to ensure that the drug residue can be processed in the next step according to the predetermined process.
