Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine extraction, specifically to a device for extracting traditional Chinese medicine components under combined pressure and temperature control. Background Technology
[0002] Extraction and concentration of Chinese herbal medicines is an important part of the processing of Chinese herbal medicines. The equipment for concentrating Chinese herbal medicines is used to extract the essential components from the Chinese herbal medicines. Most existing methods for extracting and concentrating Chinese herbal medicines involve directly putting the Chinese herbal medicines to be processed into the interior of a heating pot for heating.
[0003] Most existing devices for extracting traditional Chinese medicine simply use direct heating. Direct heating is slow in extracting the medicinal properties of the medicine and requires a long heating and boiling time, resulting in low efficiency. Some devices have improved the extraction efficiency through stirring and other methods, but the improvement is still limited.
[0004] Therefore, we propose a device for extracting traditional Chinese medicine components by combining pressure and temperature control. Summary of the Invention
[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a device for extracting traditional Chinese medicine components using a combination of pressure and temperature control.
[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: A pressure and temperature-controlled extraction device for traditional Chinese medicine components includes: an extraction tank, comprising a tank body and a tank cover that seals the tank body, with a sealable liquid outlet pipe at the bottom of the tank body; a heating component, located at the bottom of the tank body, for heating the liquid inside the tank body; a drug-filling component, detachably installed inside the tank body and in the form of a mesh box, for holding traditional Chinese medicine; a stirring component, located on the tank cover, for stirring the traditional Chinese medicine inside the drug-filling component; a pressurizing component, located on the tank body, for displacing the atmosphere and controlling the gas pressure inside the tank body; an environmental module, located on the tank cover and offset from the stirring component, for collecting data on the liquid temperature and gas pressure inside the tank body; and a controller electrically connected to the environmental module, the pressurizing component, and the heating component.
[0007] By setting up a mesh-like drug-placement component, traditional Chinese medicine (TCM) can be placed inside, preventing it from accumulating at the bottom of the tank. A stirring component agitates the TCM inside, improving extraction efficiency and saving extraction time. A pressurizing component replaces the inside of the tank with inert gas, providing a high-pressure environment. A controller adjusts the atmosphere and provides a high-pressure inert gas environment before heating. During slow heating, as the temperature rises, the controller releases gas from the pressurizing component, reducing the internal pressure and preventing excessive leaching of toxic components from the TCM. This pre-heating pressurization and slow release of pressure during heating helps extract the medicinal value of the TCM, while the slow release of pressure after temperature rises avoids excessive extraction, improving the safety of the extract. Based on existing devices, the combined use of pressure and temperature further improves the extraction efficiency of TCM.
[0008] Further specified, the tank body and the tank cover are connected and fixed by a first flange.
[0009] Further specifying, the heating assembly includes a heat-conducting arc plate, an electric heating wire, and a mounting bracket; The tank is a split type, including a straight section and a base section. The heat-conducting arc plate is fixedly installed at the bottom of the straight section, serving as the bottom surface of the straight section. The base section also has a base plate that matches the curvature of the heat-conducting arc plate, serving as the bottom surface of the base section. The base section and the straight section are fixedly connected by a second flange. When the base section and the straight section are connected, there is a cavity between the heat-conducting arc plate and the base plate. The mounting bracket is fixedly installed on the bottom surface of the heat-conducting arc plate, and the electric heating wire is ringed on the bottom surface of the heat-conducting arc plate and is mounted in the mounting bracket.
[0010] This tank design avoids direct contact between the heating element and the tank, preventing the tank from overheating. Furthermore, the modular design of the tank facilitates the inspection and replacement of the heating element.
[0011] Further defining the component, the medicine-filling assembly includes a medicine basket and lifting rods; the medicine basket is a top-opening mesh barrel shape, with its outer diameter and the inner diameter of the straight section fitting together with a clearance; the lifting rods are vertically positioned on both sides of the medicine basket, and each of the two lifting rods has a locking block on its outer top end; the top side wall of the straight section has a locking groove that matches the locking block; the medicine basket is fixed by the locking block on the lifting rod and the locking groove inside the tank, resulting in a simple structure and convenient use.
[0012] Further specifying, the stirring assembly includes a stirring motor, a stirring shaft, and a stirring head. The stirring motor is vertically mounted on the tank lid, with its output shaft pointing downwards and passing through the tank lid. The stirring shaft is fixedly connected to the output shaft of the stirring motor via a coupling. The stirring head is fixedly connected to the bottom end of the stirring shaft. When the tank lid is fixedly connected to the tank body, the stirring head is located inside the medicine basket and does not contact the bottom of the medicine basket. Using a geared motor as the stirring motor drives the stirring head to slowly stir the Chinese medicine inside the medicine basket, which can prevent the Chinese medicine from piling up and causing the medicinal materials in the middle to not be fully heated, thereby improving the extraction efficiency.
[0013] Further defining the pressurization component, it includes an argon storage tank, an inlet pipe, an outlet pipe, and an electrically controlled valve. Both the inlet and outlet pipes are horizontally connected to the upper part of the straight section and communicate with the interior of the straight section. The electrically controlled valve is located on the outlet pipe. The inlet pipe is connected to the argon storage tank via a gas pipeline. The electrically controlled valve and the controller are electrically connected. In use, the on / off valve, inlet pipe, and outlet pipe on the argon storage tank are opened to displace the air inside the tank. After the internal air is completely displaced, the electrically controlled valve on the outlet pipe is closed. When the internal pressure reaches the required pressure, the on / off valve on the argon storage tank is closed. At this point, the controller's extraction program is activated. The controller activates the heating component to heat the liquid inside the tank. The controller automatically opens and closes the electrically controlled valve to release gas based on the liquid temperature data feedback from the environmental module, and determines the timing for stopping the release based on the gas pressure data feedback from the environmental module, until the internal pressure is released to normal atmospheric pressure. This process requires minimal manual operation and has a simple structure.
[0014] Further specifying, the environmental module includes a temperature sensor and a pressure sensor. Both the temperature sensor and the pressure sensor are fixedly mounted on the tank cover and offset from the stirring motor. The probe of the temperature sensor is submerged below the liquid surface, and the probe of the pressure sensor is connected to the inside of the tank.
[0015] Further specified, the liquid outlet pipe is a two-section type. One section of the liquid outlet pipe is fixedly connected to the heat-conducting arc plate, and the other section of the liquid outlet pipe is fixedly connected to the base plate. When the base section and the straight cylinder section are connected, the two sections of the liquid outlet pipe are connected into a single pipeline. Several support legs are provided on the edge of the base section.
[0016] By designing the outlet pipe into two sections, the disassembly and assembly of the base section and the straight section are not affected. The support legs provide sufficient space for the installation of the outlet pipe.
[0017] The beneficial effects of this utility model are as follows: by setting up a pressurizing component, an environmental module and a controller, a high-pressure environment is provided before heating. During the heating process of the Chinese medicine, the high-pressure environment can extract the medicinal properties of the Chinese medicine more quickly. Furthermore, the gas pressure is gradually reduced during the temperature rise to avoid over-extraction of medicinal properties, which can greatly improve the extraction efficiency of Chinese medicine.

The stirring assembly 4 is used to stir the Chinese medicine in the medicine placement assembly 3. The stirring assembly 4 includes a stirring motor 41, a stirring shaft 42 and a stirring head 43.

[0023] By setting up a mesh-like medicine placement component 3, traditional Chinese medicine can be placed inside the component, preventing it from accumulating at the bottom of the tank 11. The stirring component 4 can stir the traditional Chinese medicine inside the placement component 3, improving the extraction efficiency and saving extraction time. By setting up a pressurizing component 5, inert gas is replaced inside the tank 11, providing a high-pressure environment. By setting up a controller 7, before the heating component 2 heats up, the controller 7 controls the pressurizing component 5 to change the atmosphere and provide a high-pressure inert gas atmosphere. During the slow heating process of the heating component 2, as the temperature rises, the controller 7 controls the pressurizing component 5 to release gas. This design reduces the internal pressure of the tank 11, preventing excessive pressure and over-dissolving of toxic components from the traditional Chinese medicine. By pressurizing before heating and slowly releasing the pressure during heating, the gas pressure helps extract the medicinal value from the traditional Chinese medicine. Slowly releasing the pressure after the temperature rises avoids excessive extraction of the medicinal components, improving the safety of the extract. Based on existing devices, the combined use of pressure and temperature further improves the extraction efficiency of the traditional Chinese medicine. This design of the tank 11 also avoids direct contact between the heating element 2 and the tank 11, preventing excessively high temperatures. Furthermore, the separate design of the tank 11 facilitates the control of the heating element 2. Inspection and replacement; the medicine basket 31 is fixed by the cooperation of the locking block 33 on the lifting rod 32 and the locking groove 16 in the tank 11, which is simple in structure and easy to use; a geared motor is used as the stirring motor 41 to drive the stirring head 43 to slowly stir the Chinese medicine inside the medicine basket 31, which can avoid the accumulation of Chinese medicine and prevent the central medicine from not being fully heated, thus improving the extraction efficiency; when in use, open the on / off valve, inlet pipe 52 and outlet pipe 53 on the argon gas storage tank 51 to replace the air inside the tank 11. After the internal air is replaced, close the electric control valve 54 on the outlet pipe 53 until the gas pressure inside the tank 11 reaches the required gas pressure, then close the valve. The on / off valve on the argon storage tank 51 is closed. At this time, the extraction program of the controller 7 is opened. The controller 7 turns on the heating component 2 to heat the liquid inside the tank 11. The controller 7 automatically opens and closes the electric control valve 54 to release gas based on the liquid temperature data feedback from the environmental module 6, and judges the release stop time based on the gas pressure data feedback from the environmental module 6 until the gas pressure inside the tank 11 is released to normal atmospheric pressure. The manual operation is minimal and the structure is simple. By setting the liquid outlet pipe 14 in two sections, it will not affect the disassembly and assembly of the base section 112 and the straight section 111. The support leg 15 is set to provide sufficient space for the installation of the liquid outlet pipe 14.
