Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine technology, specifically to a high-efficiency equipment for extracting volatile oils from traditional Chinese medicine. Background Technology

[0002] High-efficiency volatile oils of traditional Chinese medicine refer to those obtained using advanced extraction and enrichment technologies such as supercritical CO2 extraction, subcritical fluid extraction, molecular distillation, and membrane separation coupling under low temperature, low oxygen, and closed conditions. They are characterized by high extraction rate, high component retention rate, high batch consistency, low oxidation loss, and low solvent residue. Furthermore, the content of the main active ingredients, such as monoterpenes, sesquiterpenes, and aromatic compounds, is significantly higher than that of volatile oils of traditional Chinese medicine obtained by traditional methods.

[0003] High-efficiency Chinese herbal medicine volatile oil extraction equipment refers to a complete set of equipment that integrates modern extraction and separation technologies such as supercritical CO2 extraction, subcritical fluid extraction, molecular distillation, vacuum distillation, instantaneous pressure drop control, and membrane separation to achieve high-efficiency, high-purity, low-energy consumption, and low-thermal-sensitivity extraction of Chinese herbal medicine volatile oils under low-temperature, low-oxygen, and closed conditions. According to their respective extraction methods, they are also divided into co-aqueous distillation extraction equipment, water-distillation extraction equipment, and molecular distillation, etc.

[0004] However, when using the high-efficiency traditional Chinese medicine volatile oil extraction equipment using co-distillation extraction, the Chinese medicine to be extracted needs to be cut into small pieces first. The small pieces of Chinese medicine are then poured directly into the co-distillation tank and water is added for heating. Since the Chinese medicine inside the co-distillation tank is cut into small pieces before extraction, when the extraction is completed and the outlet at the lower end of the co-distillation tank is opened to discharge the water and small pieces of Chinese medicine, some of the small pieces of Chinese medicine may adhere to the inner wall of the co-distillation tank, causing contamination. Furthermore, if the next batch of processed Chinese medicine is different, cross-contamination of flavor will occur, affecting the quality of the next batch. Therefore, this does not meet the current requirements. To address this, we have proposed a high-efficiency traditional Chinese medicine volatile oil extraction equipment. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency traditional Chinese medicine volatile oil extraction device to solve the problems mentioned in the background art. In this device, the traditional Chinese medicine needs to be cut into small pieces before extraction. These pieces are then poured directly into the co-distillation tank, and water is added for heating. Because the traditional Chinese medicine inside the tank is cut into small pieces before extraction, when the extraction is completed and the outlet at the bottom of the tank is opened to discharge water and small pieces of medicine, some of the smaller pieces may adhere to the inner wall of the tank, causing contamination. Furthermore, if the next batch of medicine is different, cross-contamination of flavor may occur, affecting the quality of the next batch.

An annular shell is fixed to the lower end face of the two L-shaped lifting sleeves located inside the distillation tank. A ring of flushing heads is fixedly installed on the outer side of the lower end face of the annular shell. A water source tank located inside the annular shell is provided between the ring of flushing heads. A water source delivery pipe is provided on both sides inside the water source tank. The top ends of the two water source delivery pipes extend to the outer side of the L-shaped lifting sleeves by vertically penetrating the two L-shaped lifting sleeves respectively.

[0008] Preferably, the inner wall of the square slot has a square cross-sectional shape, the outer surface of the square rotating shaft fits against the inner wall of the square slot, and the square rotating shaft and the square slot are slidably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features an annular outer shell with a flushing head fixed to the outer side of its lower end face, located on the upper side of the inside of the distillation tank. When the discharge port located on the lower end face of the main body of the distillation tank is opened for material discharge and no water flows out, the stepper motor and flushing head are activated. As the flushing head moves downward, it flushes the inner wall of the distillation tank, thereby washing off small Chinese medicinal herbs adsorbed on the inner wall of the distillation tank. This technical solution improves the functionality of the equipment and prevents cross-contamination of flavors if the next batch of processed Chinese medicinal herbs is different, ensuring its quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] The main body 1 (model FYF-20L), stepper motor 3 (model DM542), and threaded lifting rod 5 (model M16) mentioned in this utility model can all be obtained from the market or through private customization.

[0021] Please see Figures 1 to 3An embodiment of this utility model provides: a high-efficiency traditional Chinese medicine volatile oil extraction device, including a co-water distillation tank body 1, a distillation tank 2 inside the co-water distillation tank body 1, a stepper motor 3 fixedly installed inside the shell of the co-water distillation tank body 1 on both sides of the distillation tank 2, the output shaft of the stepper motor 3 is connected to a square rotating shaft 4 through a coupling, a threaded lifting rod 5 is provided on the outer side of the top end of the square rotating shaft 4 and is connected to the co-water distillation tank body 1 through a threaded structure, a square slot 6 is provided at the middle position of the lower end face of the threaded lifting rod 5, and the square rotating shaft 4 is inserted into the interior of the square slot 6;

[0022] The upper end face of the threaded lifting rod 5 is connected to an L-shaped lifting sleeve 7 via a roller bearing. The bottom end of the L-shaped lifting sleeve 7 passes through the upper end face of the co-water distillation tank body 1 to enter the interior of the distillation tank 2. An annular shell 9 is fixed to the lower end face of the two L-shaped lifting sleeves 7 located inside the distillation tank 2. A ring of flushing heads 11 is fixedly installed on the outer side of the lower end face of the annular shell 9. A water source tank 10 located inside the annular shell 9 is provided between the ring of flushing heads 11. A water source delivery pipe 8 is provided on both sides inside the water source tank 10. The top ends of the two water source delivery pipes 8 extend to the outer side of the L-shaped lifting sleeves 7 by vertically penetrating the two L-shaped lifting sleeves 7 respectively. A control panel 16 is fixedly installed on the lower side of the rear end face of the co-water distillation tank body 1, and the control panel 16 is electrically connected to the co-water distillation tank body 1. The equipment can be controlled through the control panel 16.

[0023] The upper end of the co-distillation tank body 1 is covered with a tank cover 14, and the upper end of the tank cover 14 is connected to a separation mechanism 15. The lower end of the co-distillation tank body 1 is equipped with a discharge port. When the equipment is needed, the Chinese herbal medicine to be extracted is cut into small pieces, the Chinese herbal medicine cut into small pieces is poured directly into the interior of the distillation tank 2, water is added, the tank cover 14 is closed, the co-distillation tank body 1 is started to heat it, and the distillation operation is carried out. At this time, the distillation time is set according to the type of medicinal material. During the distillation process, the water vapor containing volatile oil will enter the interior of the separation mechanism 15 and be separated, thereby extracting the highly efficient volatile oil of the Chinese herbal medicine.

[0024] The inner wall of the square slot 6 has a square cross-section. The outer surface of the square rotating shaft 4 fits against the inner wall of the square slot 6, and the square rotating shaft 4 and the square slot 6 are slidably connected. During the extraction operation, a water supply hose is connected to the upper end of the water supply pipe 8, and the other end of the water supply hose is connected to the water supply equipment.

[0025] After the extraction is completed, the discharge port located on the lower end face of the main body 1 of the co-water distillation tank is opened for discharge. When no more water flows out, the stepper motor 3 water supply device is started to supply water to the inside of the water supply pipe 8 and the water tank 10 connected to the inside of the water supply pipe 8. When water enters the inside of the water tank 10, the water inside the water tank 10 is drawn out by a ring of flushing heads 11 fixedly installed on the lower end face of the annular shell 9 and sprayed onto the inner wall of the distillation tank 2 to flush the small Chinese medicines adsorbed on the inner wall of the distillation tank 2.

[0026] When the flushing head 11 is started, the stepper motor 3 is started. The stepper motor 3 can drive the square rotating shaft 4 connected to it to rotate. Since the outer surface of the square rotating shaft 4 is in contact with the inner wall of the square slot 6 located at the lower end of the threaded lifting rod 5, when the square rotating shaft 4 rotates, the threaded lifting rod 5 will rotate along with it. Through the threaded structure between the threaded lifting rod 5 and the main body 1 of the common water distillation tank, the rotating threaded lifting rod 5 will move up and down. At this time, the threaded lifting rod 5 moves down. During the downward movement of the threaded lifting rod 5, the annular shell 9 connected to it through the L-shaped lifting sleeve 7 and the flushing head 11 installed on the outer surface of the annular shell 9 will move down together. Through the flushing of the downward moving flushing head 11, it can be ensured that the small Chinese medicines adsorbed on the inner wall of the distillation tank 2 can be completely flushed.

[0027] The above technical solution can prevent the complete discharge of extracted Chinese medicine, thereby improving the functionality of the equipment. Furthermore, if the next batch of processed Chinese medicine is different from it, it can also prevent cross-contamination of flavors and ensure its quality.

[0028] Once a single flushing operation is completed, move the annular outer shell 9 back to its original position, and then repeat the above operation.

[0029] A sealing sleeve 12 is fixedly fitted on the lower side of the outer surface of the L-shaped lifting sleeve 7. An annular sealing groove 13 is provided on the outer side of the top end of the sealing sleeve 12, located on the inner wall of the upper end of the distillation tank 2. The outer surface of the sealing sleeve 12 is in contact with the inner wall of the annular sealing groove 13, and the sealing sleeve 12 and the annular sealing groove 13 are slidably connected. By fixing the sealing sleeve 12 on the outer surface of the L-shaped lifting sleeve 7 and the annular sealing groove 13 located on the outer side of the top end of the sealing sleeve 12, it is possible to prevent water vapor inside the co-water distillation tank body 1 from drifting to the outside through the connection between the L-shaped lifting sleeve 7 and the co-water distillation tank body 1 during the extraction operation.

[0030] Below the stepper motor 3 is a protective cover plate located on the lower end face of the co-distillation tank body 1, and the co-distillation tank body 1 and the protective cover plate are fixed together by screws; the protective cover plate can seal and protect the stepper motor 3, and when the stepper motor 3 fails, the protective cover plate can be removed to repair the stepper motor 3.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
