Description

Technical Field

[0001] The utility model belongs to the technical field of pure oil extraction, and particularly relates to a novel camphor oil pure oil extraction device. Background Art

[0002] Absolute oil is one of the important fragrance raw materials on the market. Currently, most of the essential oils of camphor are extracted by steam.

[0003] At present, a Chinese utility model with publication number: CN211394410U discloses a highly efficient clean oil extraction device, including a device body, a motor is screwed and fixed to the top of the device body by bolts, a feed port is fixed to the bottom of the motor, connecting plates are welded at both ends of the device body, a protective cover is arranged on one side of the connecting plate and located on the front surface of the device body, a hinge is rotatably connected to the connection between one end of the protective cover and the connecting plate, and a transparent lens is bonded to the middle position of the protective cover by glue; by designing a protective cover on the front surface of the device body and designing a pressing plate at both ends of the inner surface of the protective cover, it is avoided that it is inconvenient to protect the front surface and insert an advertising board during use, and the torsion spring can be used to rotate in place at both ends of the connecting shaft, and at this time, the pressing plate is pressed against the upper surface of the advertising board and fixed by the elastic deformation of the torsion spring, which solves the problem of inconvenience in protecting the front surface and inserting the advertising board.

[0004] However, although the traditional method of extracting camphor essential oil with steam can extract a certain amount of essential oil, the extracted essential oil has a lower content of aromatic substances than the pure oil extracted by volume, so the fragrance is poor and the antioxidant property is poor. At the same time, the extraction rate of camphor essential oil extracted by steam distillation is low, and it is difficult to fully extract it, so not only the energy consumption is high, but also the oil yield and oil quality are relatively average. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of camphor oil extraction equipment, which has the advantages that compared with the essential oil extracted by traditional steam, the pure oil extracted by the equipment has a fuller smell and stronger antioxidant properties. In addition, the container volume is large, and the contact area between the solvent and the camphor leaf powder is large, which can increase the extraction efficiency and oil yield of the pure oil.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a novel camphor oil extraction equipment, including an electric heating jacket, a round-bottom flask is fixedly installed inside the electric heating jacket, an extraction container is installed on the top of the round-bottom flask, a condensation container is installed on the top of the extraction container, a serpentine cooling coil is fixedly connected inside the condensation container, the round-bottom flask and the extraction container and the extraction container and the condensation container are fixedly connected with connecting flanges, the round-bottom flask and the extraction container and the condensation container are fixedly connected through the connecting flanges, one end of the serpentine cooling coil passes through the condensation container and is fixedly connected to a cold water tank, and the other end passes through the condensation container and is fixedly connected to a vacuum cooling pump.

[0007] Adopting the above technical scheme, by in the extraction of plant components, utilizing the principle of similar dissolving, the active ingredient in the plant is dissolved in an organic solvent, and then the solvent is removed to obtain the desired substance. In this process, the organic solvent plays an important role, and the difference in properties such as physicochemistry existing between different organic solvents often causes the type and content of the active ingredient of the extracted component, physicochemical properties, etc. to be different. Oil camphor leaf powder is put into an extraction container, by continuously heating the organic solvent in a round-bottomed flask, boiling and evaporating it, then condensing back into the inside of the round-bottomed flask, to leaching oil camphor leaf powder, then by continuous evaporation, condensation and reflux, to extract it repeatedly, so that the clean oil component in the oil camphor leaf is retained in the round-bottomed flask, thereby improving the extraction efficiency and oil yield of clean oil. At the same time, it is ensured that the clean oil smell is fuller and improves antioxidant properties.

[0008] The utility model is further configured as follows: a thermometer is fixedly connected through one side of the interior of the round-bottom flask.

[0009] The adoption of the technical solution makes it easy to monitor the heating temperature of the organic solvent inside the round-bottom flask to prevent accidents.

[0010] The utility model is further configured as follows: a level meter used in conjunction with the round-bottom flask is fixedly installed on one side of the exterior of the electric heating jacket.

[0011] By adopting the above technical solution, the mouth of the round-bottom flask can be kept parallel to the ground as much as possible, thereby improving the stability of placement.

[0012] The utility model is further configured as follows: a sealing ring which is respectively used in conjunction with the round bottom flask, the extraction container and the condensation container is bonded inside the connecting flange.

[0013] By adopting the technical solution, the sealing performance of the round-bottom flask, the extraction container and the condensation container after they are fixedly connected by the connecting flange is improved, thereby preventing gas and solvent from leaking out.

[0014] The utility model is further configured as follows: a pressure relief pipe is fixedly connected to the top of the condensation container.

[0015] By adopting the above technical solution, when there is too much steam inside the condensation container and the serpentine cooling coil cannot condense it in time, it can be discharged, thereby avoiding the generation of high pressure inside the condensation container to avoid accidents.

[0016] The utility model is further configured as follows: a sieve plate is fixedly connected to one side of the extraction container close to the round-bottom flask.

[0017] Using the above technical solution, the sieve plate 11 can be a mesh plate or a filter paper board. If a mesh plate is used, camphor leaves can be used for extraction. If a filter paper board is used, camphor leaves can be used for extraction to prevent camphor and impurities on its surface from falling into the round-bottom flask.

[0018] In summary, the utility model has the following beneficial effects:

[0019] By using the principle of similar dissolving in the extraction of plant components, the active ingredients in the plant are dissolved in an organic solvent, and then the solvent is removed to obtain the desired substance. In this process, the organic solvent plays an important role, and the differences in the physical and chemical properties between different organic solvents often lead to differences in the types and contents of the active ingredients of the extracted components, the physicochemical properties, etc. The oil camphor leaf powder is placed in an extraction container, and the organic solvent in the round-bottomed flask is continuously heated to boil and evaporate, and then condensed back into the inside of the round-bottomed flask to extract the oil camphor leaf powder, and then repeatedly extracted by continuous evaporation, condensation and reflux, so that the clean oil component in the oil camphor leaf is retained in the round-bottomed flask, thereby improving the extraction efficiency and oil yield of the clean oil. At the same time, it is ensured that the smell of the clean oil is fuller and the antioxidant property is improved. BRIEF DESCRIPTION OF THE DRAWINGS

In this process, organic solvents play an important role, and the differences in physical and chemical properties between different organic solvents often lead to differences in the types and contents of the active ingredients of the extracted components, physical and chemical properties, etc. Put the oil camphor leaf powder into the extraction container 3, and continuously heat the organic solvent in the round-bottom flask 2 to make it boil and evaporate, and then condense it back into the round-bottom flask 2 to extract the oil camphor leaf powder, and then repeatedly extract it by continuous evaporation, condensation and reflux, so that the pure oil components in the oil camphor leaves are retained in the round-bottom flask 2, thereby improving the extraction efficiency and oil yield of the pure oil. At the same time, it is ensured that the smell of the pure oil is fuller and the oxidation resistance is improved.

[0026] refer to Figure 1 , Figure 2 A thermometer 6 is fixedly connected to one side of the round-bottom flask 2 to facilitate monitoring the heating temperature of the organic solvent in the round-bottom flask 2 to prevent accidents.

[0027] refer to Figure 1 A level 7 used in conjunction with the round-bottom flask 2 is fixedly mounted on one side of the outer portion of the electric heating jacket 1, which can ensure that the mouth of the round-bottom flask 2 is parallel to the ground as much as possible, thereby improving the stability of placement.

[0028] refer to Figure 2 A sealing ring 9 is bonded to the inside of the connecting flange 8, which is used in conjunction with the round-bottom flask 2, the extraction container 3 and the condensation container 4 respectively, to improve the sealing performance of the round-bottom flask 2, the extraction container 3 and the condensation container 4 after being fixedly connected by the connecting flange 8, thereby preventing gas and solvent from leaking out.

[0029] refer to Figure 1 , Figure 2 The top of the condensation container 4 is fixedly connected with a pressure relief pipe 10, which can discharge the steam inside the condensation container 4 when there is too much steam and the serpentine cooling coil 5 cannot condense it in time, thereby avoiding the generation of high pressure inside the condensation container 4 to avoid accidents.

If a mesh plate is used, camphor leaves can be used for extraction. If a filter paper board is used, camphor leaves can be used for extraction to prevent camphor and impurities on its surface from falling into the round-bottom flask 2.

[0031] Usage process: First, put the camphor leaf powder to be extracted for pure oil into the extraction container 3, then use the connecting flange 8 to lock and connect the lower mouth of the extraction container 3 and the bottle mouth of the round-bottom flask 2, and ensure that the connection is tight and there is no air leakage. After checking that everything is correct, add about 7 to 8L of n-hexane into the extraction container 3, and after the siphon is stable, lock and connect the upper mouth of the extraction container 3 and the lower mouth of the condensation container 4 with the connecting flange 8, and also ensure that the connection is tight and there is no air leakage.

[0032] After that, the serpentine cooling coil 5 is connected to the vacuum cooling pump, and the vacuum cooling pump and the electric heating jacket 1 are turned on, and the upper temperature of the cooling temperature is set to 5°C, the lower temperature is set to 0°C, and the temperature of the electric heating jacket 1 is set to 80°C. After setting, observe the state of the n-hexane in the round-bottom flask 2, start timing from its boiling, and extract for 7-8 hours. During extraction, be sure to send someone to guard the electric heating jacket 1 to avoid accidents.

[0033] After the extraction is completed, turn off the switches of the electric heating jacket 1 and the vacuum cooling pump, and disconnect the power supply. After the device is cooled, gently wipe off the condensed water on the surface of the condensation container 4 and the serpentine cooling coil 5 and the device connection flange 8, then open the flanges of the condensation container 4 and the upper mouth of the extraction container 3, stabilize the lower half of the device, slowly remove the condensation container 4 and the serpentine cooling coil 5 from the upper mouth of the extraction container 3, and fix them to facilitate the next operation. Then stabilize the extraction container 3, open the flanges of the round-bottomed flask 2 and the lower mouth of the electric heating jacket 1, remove the extraction container 3, pour out the extracted camphor leaf powder, and filter out the remaining n-hexane in the extraction container 3. Finally, take out the round-bottomed flask 2 and pour out the extracted n-hexane.

[0034] Add oven-dried clay to the poured n-hexane for decolorization. When the n-hexane solution becomes clear and transparent, and there is no obvious green, the decolorization is complete. Then use a Buchner funnel to filter the successfully decolorized n-hexane to remove the clay and residual camphor leaves. Then, use a rotary evaporator to evaporate the filtered n-hexane solution. Pour the n-hexane solution into an eggplant-shaped flask, set the temperature of the water bath of the rotary evaporator to 40°C, then fasten the eggplant-shaped flask and the lower mouth of the rotary evaporator with a lock, and perform rotary evaporation at a speed of 80 rpm under an environment of 100 Pa until no n-hexane condenses out and there is no obvious liquid in the eggplant-shaped flask, that is, the rotary evaporation is complete.

[0035] Open the vent plug, wait until the barometer returns to normal, remove the eggplant-shaped flask, scrape the paste on the wall with a long-handled spoon, and dissolve it in 95% ethanol solution. After scraping, put the ethanol solution containing the extract into the freezer of the refrigerator and store it at -20℃ for 14 hours.

[0036] The frozen ethanol solution is filtered with a Buchner funnel to remove solid impurities in the solution. The filtered ethanol solution is poured into an eggplant-shaped flask, which is then connected to a rotary evaporator. The water bath is set to 37°C, and the rotary evaporation is performed at a speed of 80 rpm under an environment of 80 Pa until no ethanol liquid condenses. The substance left in the eggplant-shaped flask is the pure oil.
