Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine extraction and separation technology, specifically relating to an integrated system suitable for the extraction and separation of heat-sensitive components from traditional Chinese medicine. Background Technology

[0002] The active ingredients of traditional Chinese medicine (TCM) are the core material basis for its efficacy. Upgrading from traditional to precision medicine hinges on efficient extraction technology. However, existing technologies have inherent limitations when processing heat-sensitive active ingredients (such as volatile oils, terpenes, some glycosides, and alkaloids) in TCM: traditional methods like decoction and reflux are time-consuming and high-temperature, leading to volatilization, oxidation, or decomposition of heat-sensitive ingredients and loss of activity; while efficient modern extraction technologies like ultrasound-assisted extraction and microwave-assisted extraction suffer from heat generation, similarly threatening the activity of heat-sensitive ingredients; supercritical fluid extraction and enzymatic extraction, although gentler, are complex and costly, making them unsuitable for large-scale continuous industrial production. Therefore, there is an urgent need in this field for a novel solution that balances extraction efficiency, protection of heat-sensitive ingredient activity, and low-cost continuous production. Summary of the Invention

[0003] To achieve the above objectives, this invention provides an integrated system for the extraction and separation of heat-sensitive components from traditional Chinese medicine. By creatively combining an ultrasonic-assisted extraction module with a jacketed hot-cold circulation system, the system utilizes the hot-cold circulation system to counteract and precisely control the heat generated during ultrasonic operation in real time. This achieves efficient extraction while fundamentally solving the technical problem of inactivation of heat-sensitive components from traditional Chinese medicine due to temperature rise. Furthermore, a rapid liquid-residue separation system is integrated, ensuring that the entire device can adapt to low-cost, large-scale continuous production processes, overcoming the shortcomings of existing high-end technologies that are complex and difficult to implement continuously.

[0004] The purpose of this utility model is achieved through the following technical solution: an integrated system for the extraction and separation of heat-sensitive components of traditional Chinese medicine, including a stirred extraction tank, a cooler, a cyclone centrifuge, a stirring device, a power delivery pump, an ultrasonic generator, and an air lifting device. The stirred extraction tank includes a tank body with a discharge port at the bottom and a jacketed cylinder on the side wall; an annular cavity is left between the jacketed cylinder and the tank body, and the cavity has a liquid inlet and a liquid outlet; the tank body is vertically arranged by multiple support legs; the top of the tank body also has a first feed inlet and a second feed inlet; a stirring device is installed on the top of the tank body; and multiple ultrasonic generators are installed in a ring along the side wall of the tank body. The cooler is located on one side of the stirring extraction tank, and its outlet is connected to the liquid inlet through a pipe, while its inlet is connected to the liquid outlet through a pipe. The outlet of the stirred extraction tank is connected to the cyclone centrifuge via a pipeline, and a power delivery pump is installed on the pipeline; the cyclone centrifuge is equipped with an air-lift device.

[0005] As a further optimization of this utility model, the stirring device consists of a base, a frame, a motor, a stirring shaft, a coupling, and stirring blades; the base is fixed to the top of the tank, and the motor is mounted on the base through the frame; the stirring shaft passes through the top of the tank, its upper end is connected to the motor through the coupling, and its lower end extends into the tank; multiple stirring blades are provided on the stirring shaft located inside the tank.

[0006] As a further optimization of this utility model, the lower part of the tank is a cone structure, the discharge port is located at the bottom of the cone structure, and a rotary valve is provided on the pipe at the discharge port.

[0007] As a further optimization of this utility model, a No. 1 valve is provided on the pipe connected to the outlet of the refrigerator, and a No. 2 valve is provided on the pipe connected to the inlet of the refrigerator.

[0008] As a further optimization of this utility model, the liquid inlet is located on one side of the lower part of the cavity, and the liquid outlet is located on the other side of the upper part of the cavity.

[0009] Beneficial effects: This invention increases the transfer rate of effective components of Chinese herbal medicine in the extractant and shortens the extraction time by setting a stirring device in the extraction tank and installing an ultrasonic generator in a ring on the side wall of the tank. The combination design of the jacket cylinder and the cooler on the extraction tank realizes the hot and cold cycle, effectively suppressing the temperature rise caused by ultrasonic operation, thereby ensuring that the activity of heat-sensitive components of Chinese herbal medicine is preserved.

[0011] Embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art will understand that the following embodiments are for illustrative purposes only and should not be construed as limiting the scope of the present invention. Where specific techniques, connections, or conditions are not specified in the embodiments, they are performed in accordance with the techniques, connections, or conditions described in the literature in the field or according to the product instructions. Materials, instruments, or equipment used without specified manufacturers are all conventional products that can be obtained through purchase.

[0012] like Figure 1 As shown, the present invention provides an integrated system for the extraction and separation of heat-sensitive components of traditional Chinese medicine, including a stirred extraction tank 1, a cooler 2, a cyclone centrifuge 3, a stirring device 4, a power delivery pump 5, an ultrasonic generator 6, and an air lifting device 7. The stirred extraction tank 1 includes a tank body 11, with a discharge port 12 at the bottom and a jacketed cylinder 13 on the side wall. An annular cavity 14 is provided between the jacketed cylinder 13 and the tank body 11, with an inlet 15 and an outlet 16 on the cavity 14. The inlet 15 and outlet 16 are arranged diagonally opposite each other to ensure the longest possible flow path for the fluid within the cavity. The inlet 15 is located on one side of the lower part of the cavity 14, and the outlet 16 is located on the other side of the upper part of the cavity 14. The tank body 11 is vertically mounted via multiple support legs 17. The top of the tank body 11 also has a first inlet 18 and a second inlet 19, both equipped with opening and closing doors. A stirring device 4 is installed on the top of the tank body 11. Multiple ultrasonic generators 6 are annularly mounted along the side wall of the tank body 11. The cooler 2 is located on one side of the stirring extraction tank 1. Its outlet 21 is connected to the liquid inlet 15 through a pipe, and its inlet 22 is connected to the liquid outlet 16 through a pipe. A first valve 9 is provided on the pipe connected to the outlet 21 of the cooler 2, and a second valve 10 is provided on the pipe connected to the inlet 22 of the cooler 2. The discharge port 12 of the stirring extraction tank 1 is connected to the cyclone centrifuge 3 through a pipeline, and a power delivery pump 5 is installed on the pipeline; the cyclone centrifuge 3 is equipped with an air lifting device 7.

[0013] As a further implementation of this solution, the stirring device 4 consists of a base 41, a frame 42, a motor 43, a stirring shaft 44, a coupling 45, and stirring blades 46. The base 41 is fixed to the top of the tank 11, and the motor 43 is mounted on the base 41 through the frame 42. The stirring shaft 44 passes through the top of the tank 11, and its upper end is connected to the motor 43 through the coupling 45, while its lower end extends into the tank 11. Multiple stirring blades 46 are provided on the stirring shaft 44 located inside the tank 11.

[0014] As a further implementation of this scheme, the lower part of the tank 11 is a cone structure, the discharge port 12 is located at the bottom of the cone structure, and a rotary valve 8 is provided on the pipe at the discharge port 12.

[0015] The working principle of this utility model is as follows: Open valve 9 and valve 10 to turn on the cooler 2; the coolant comes out from outlet 21 and enters the cavity 14 of the stirred extraction tank 1 through inlet 15. After circulating around the stirred extraction tank 1, it comes out from outlet 16 and flows back to the cooler 2 through the pipeline for cooling. During this circulation, rotary valve 8 is closed; turn on the stirring device 4 to make the stirring blades rotate; then put the herbal extract into the stirred extraction tank 1 through inlet 19; the 20-300 mesh herbal powder is put into the stirred extraction tank 1 through inlet 18; when the total volume of the herbal powder and extract reaches 60% to 85% of the total volume of the stirred extraction tank 1, stop feeding, and then turn on the ultrasonic generator 6.

[0016] After ultrasonic stirring and extraction of the raw material in the stirring extraction tank 1 for 10-60 minutes, the power transfer pump 5, rotary valve 8, air-lift device 7, and cyclone centrifuge 3 are turned on. The raw material enters the cyclone centrifuge 3 through the tangential inlet pipe 31 at a certain flow rate via the power transfer pump 5, and moves in a circular external swirling motion along the outer wall of the cyclone centrifuge 3 to the bottom. When the liquid reaches the lower end of the cone, it rotates upward in the same direction in the cyclone dust collector, continuing to perform an internal spiral motion. Finally, the liquid is discharged from the device through the drain pipe 32. At the same time, under the action of centrifugal force, the residue descends along the outer wall of the cyclone centrifuge 3 to the bottom, and is discharged through the residue outlet pipe 33 under the action of the air-lift device 7.

[0017] If the required extraction time for the medicinal materials is long or the amount of raw material to be extracted is small, the above steps can be performed intermittently. If the required extraction time for the medicinal materials is short, all equipment can be started simultaneously, with continuous feeding from inlet 18 and inlet 19; and continuous discharge from drain pipe 32 and slag pipe 33. If the required material-to-liquid ratio for the medicinal materials extraction is large, all equipment can be started simultaneously, and part of the slag from the outlet of slag pipe 33 can enter inlet 18 for recycling extraction. A hydraulic cover 34 is provided below the cyclone centrifuge 3, which provides strong locking force to ensure sealing during the extraction process. When the air-lift device cannot discharge slag due to excessively high material viscosity or density, the hydraulic cover can be opened for manual cleaning.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
