Description

Technical Field

[0001] This invention belongs to the field of Curcuma zedoaria oil extraction technology, specifically relating to an Curcuma zedoaria oil extraction device and extraction method. Background Technology

[0002] Curcuma zedoaria has the effects of promoting qi circulation and breaking up blood stasis, eliminating stagnation and relieving pain, and promoting bile secretion and killing bacteria. The Curcuma zedoaria oil extracted from it is of high quality and can be used as a raw material for anti-cancer drugs in the preparation of injections.

[0003] Furthermore, the turmeric oil extracted from Curcuma zedoaria has a direct inhibitory effect on respiratory syncytial virus, and clinical evidence has proven it to be a nemesis of viral infections. It has a direct inactivating effect on influenza A1 and A3 viruses, fighting viruses by dissolving viral particles, and also has antibacterial and anti-inflammatory effects against Staphylococcus aureus, Escherichia coli, and Salmonella spp.

[0004] Currently, the equipment used to extract turmeric oil from Curcuma zedoaria is relatively rudimentary, and the processes used are all traditional dry steaming, which consumes a lot of energy, causes heavy pollution, has low efficiency, low oil yield, and inconsistent oil quality. Summary of the Invention

[0005] In view of this, the present invention provides an apparatus and method for extracting turmeric oil, in order to solve the problems that the existing equipment used to extract turmeric oil from Curcuma zedoaria is relatively simple, the process used is all traditional dry steaming, which has high energy consumption, heavy pollution, low efficiency, low oil yield, and inconsistent oil quality.

[0006] The technical solution adopted in this invention is as follows:

[0007] An apparatus for extracting turmeric oil includes an evaporator, an inlet pipe, and a distillation kettle. The distillation kettle is fitted with a baffle plate, through which multiple air outlets are formed. An inlet chamber is formed between the baffle plate and the bottom of the distillation kettle. The two ends of the inlet pipe are connected to the distillation kettle and the inlet chamber, respectively. A condenser is connected to one side of the distillation kettle via a first pipe, and a fractionator is connected to one side of the condenser via a second pipe. A stirring device is also provided inside the distillation kettle. The bottom of the stirring shaft of the stirring device is rotatably connected to the bottom wall of the inlet chamber. A rotating device for driving the stirring shaft is also provided inside the inlet chamber.

[0008] In this technical solution, when it is necessary to extract turmeric oil, turmeric is put into a distillation kettle, and then the evaporator and rotating device are started. The evaporator heats the distilled water inside to generate steam. The steam acts on the turmeric through the vent and forms volatile oil. At the same time, the rotating device continuously stirs the turmeric, so that the turmeric is heated evenly and the oil yield of turmeric is improved.

[0009] Preferably, the rotating device includes a plurality of fan blades, which are spaced apart circumferentially on the side wall of the stirring shaft.

[0010] In this technical solution, the power source of the stirring device mainly comes from steam and fan blades. When steam enters the air intake, it drives the fan blades to rotate, and the rotation of the fan blades drives the stirring shaft to rotate. Thus, the stirring device can automatically stir the turmeric without the use of external electrical appliances, saving resources.

[0011] Preferably, the air intake pipe includes an air jet port communicating with the air intake chamber, the air jet port facing the sidewall of the fan blade.

[0012] In this technical solution, since the exhaust direction of the jet nozzle is towards the fan blade, the steam can be directly sprayed onto the fan blade after it is ejected from the jet nozzle, which makes the external force on the fan blade greater and makes it easier to drive the stirring shaft to rotate.

[0013] Preferably, the end of the fan blade facing the air outlet has an inwardly concave arc-shaped surface.

[0014] In this technical solution, since the end of the fan blade facing the nozzle has an inwardly concave arc surface, when the airflow is ejected from the nozzle and acts on the fan blade, the airflow will converge to the center of the arc surface due to the design of the arc surface, resulting in a better boosting effect.

[0015] Preferably, the thickness of the fan blade at the end furthest from the stirring shaft is less than the diameter of the jet nozzle.

[0016] In this technical solution, since the thickness of the fan blade at the end away from the stirring shaft is less than the diameter of the air jet, the fan blade avoids blocking the air jet when it is aligned with the air jet.

[0017] Preferably, a high-pressure valve is provided inside the air intake pipe.

[0018] In this technical solution, the high-pressure valve ensures that the steam can only be ejected from the jet nozzle after it reaches a certain pressure in the intake pipe.

[0019] Preferably, the diameter of the intake pipe gradually decreases in the direction away from the evaporator.

[0020] In this technical solution, because the diameter of the air pipe gradually decreases away from the evaporator, the steam is continuously compressed before it is ejected from the nozzle, and the airflow speed continuously increases. Finally, when the steam is ejected from the nozzle, the airflow speed is increased, making it easier to drive the fan blades to rotate.

[0021] Preferably, the stirring device further includes stirring blades disposed on the side wall of the stirring shaft, the stirring blades being located above the partition plate.

[0022] Preferably, the top of the distillation vessel is provided with a feed inlet, and the feed inlet is provided with an on / off valve.

[0023] A method for extracting turmeric oil includes the following steps:

[0024] Step 1: Add the pretreated Curcuma zedoaria into the distillation vessel through the feed inlet;

[0025] Step 2: Start the evaporator. The evaporator heats the distilled water inside to generate steam. When the steam in the inlet pipe accumulates to a certain pressure, the high-pressure valve opens. The steam is injected into the inlet chamber from the jet nozzle and acts on the fan blades. The fan blades, under the action of the steam, drive the stirring shaft to rotate, so that the stirring blades on the stirring shaft continuously stir the turmeric in the distillation vessel. At the same time, the steam acts on the turmeric through the outlet and forms volatile oil.

[0026] Step 3: The volatile oil enters the condenser tower through the first pipe and is condensed. Then it is fed into the fractionation tank for fractionation. The liquid obtained after fractionation is Curcuma oil.

[0027] Preferably, the pretreatment includes pre-treating Curcuma zedoaria and slicing it, and then sieving the slices through a 24-mesh sieve.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In this invention, when it is necessary to extract Curcuma zedoaria oil, Curcuma zedoaria is put into a distillation kettle, and then the evaporator and rotating device are started. The evaporator heats the distilled water inside to generate steam. The steam acts on Curcuma zedoaria through the steam outlet and forms volatile oil. At the same time, the rotating device continuously stirs Curcuma zedoaria, so that Curcuma zedoaria is heated evenly and the oil yield of Curcuma zedoaria is improved.

[0030] 2. In this invention, the power source of the stirring device mainly comes from steam and fan blades. When steam enters the air intake, it will drive the fan blades to rotate. The rotation of the fan blades will drive the stirring shaft to rotate, thereby enabling the stirring device to automatically stir the turmeric without the use of external electrical appliances, thus saving resources.

[0031] 3. In this invention, since the diameter of the air pipe gradually decreases away from the evaporator, the steam is continuously compressed before it is ejected from the jet nozzle, and the airflow speed continuously increases. Finally, when the steam is ejected from the jet nozzle, the airflow speed increases, making it easier to drive the fan blades to rotate. Attached Figure Description

[0046] Example 1

[0047] like Figure 1-5 As shown in the figure, an embodiment of the present invention discloses an evaporator for extracting turmeric oil, including an evaporator 20, an air inlet pipe 21, and a distillation kettle 10. The distillation kettle 10 is equipped with a partition 12, and a plurality of air outlet holes 13 are provided through the partition 12. An air inlet chamber 14 is formed between the partition 12 and the bottom of the distillation kettle 10. The two ends of the air inlet pipe 21 are respectively connected to the distillation kettle 10 and the air inlet chamber 14. A condenser 40 is connected to one side of the distillation kettle 10 through a first pipe 30, and a fractionator 60 is connected to one side of the condenser 40 through a second pipe 50. The distillation kettle 10 is also equipped with a stirring device. The bottom of the stirring shaft 70 of the stirring device is rotatably connected to the bottom wall of the air inlet chamber 14. The air inlet chamber 14 is also equipped with a rotating device for driving the stirring shaft 70 to rotate. It should be noted that when extracting turmeric oil, the turmeric is put into the distillation kettle 10, and then the evaporator 20 and the rotating device are started. The evaporator 20 heats the distilled water inside to generate steam. The steam acts on the turmeric through the vent 13 and forms volatile oil. At the same time, the rotating device continuously stirs the turmeric, so that the turmeric is heated evenly and the oil yield of the turmeric is improved.

[0048] like Figure 2 , Figure 3 , Figure 4 As shown in this embodiment, the rotating device includes a plurality of fan blades 15, which are spaced apart circumferentially on the side wall of the stirring shaft 70. It should be noted that the power source of the stirring device mainly comes from steam and the fan blades 15. When steam enters the air intake, it drives the fan blades 15 to rotate, which in turn drives the stirring shaft 70 to rotate. This allows the stirring device to automatically stir the turmeric without the use of external electrical appliances, saving resources.

[0049] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, the air intake pipe 21 includes a jet nozzle 23 communicating with the air intake chamber 14, and the jet nozzle 23 faces the side wall of the fan blade 15. It should be noted that, since the exhaust direction of the jet nozzle 23 is towards the fan blade 15, the steam ejected from the jet nozzle 23 can be directly sprayed onto the fan blade 15, resulting in a greater external force on the fan blade 15 and making it easier to drive the stirring shaft 70 to rotate.

[0050] like Figure 2 , Figure 3 , Figure 4 As shown, in this embodiment, the end of the fan blade 15 facing the jet nozzle 13 has an inwardly concave arc-shaped surface. It should be noted that, because the end of the fan blade facing the jet nozzle has an inwardly concave arc-shaped surface, when the airflow is ejected from the jet nozzle and acts on the fan blade, the airflow will converge to the center of the arc-shaped surface due to the design of the arc-shaped surface, resulting in a better boosting effect.

[0051] like Figure 4 As shown, in this embodiment, the thickness of the end of the fan blade 15 away from the stirring shaft 70 is less than the diameter of the jet nozzle 23. It should be noted that, because the thickness of the end of the fan blade away from the stirring shaft is less than the diameter of the jet nozzle, the fan blade avoids clogging the jet nozzle when the fan blade is aligned with the jet nozzle.

[0052] like Figure 2 As shown, in this embodiment, a high-pressure valve 22 is provided inside the air intake pipe 21. It should be noted that the high-pressure valve 22 ensures that the steam can only be ejected from the jet nozzle 23 after reaching a certain pressure in the air intake pipe 21.

[0053] like Figure 5 As shown, in this embodiment, the diameter of the air inlet pipe 21 gradually decreases in the direction away from the evaporator 20. It should be noted that, because the diameter of the air pipe gradually decreases in the direction away from the evaporator 20, the steam is continuously compressed before it is ejected from the jet nozzle 23, and the airflow speed continuously increases. Finally, when the steam is ejected from the jet nozzle 23, the airflow speed is increased, making it easier to drive the fan blade 15 to rotate.

[0054] like Figure 2 , Figure 3 As shown, in this embodiment, the stirring device further includes stirring blades 71 disposed on the side wall of the stirring shaft 70, and the stirring blades 71 are located above the partition plate 12.

[0055] like Figure 2 , Figure 3 As shown in this embodiment, the top of the distillation vessel 10 is provided with a feed inlet 11, and an on / off valve is provided at the feed inlet 11.

[0056] The working principle of this embodiment is as follows: First, the pretreated Curcuma zedoaria is put into the distillation vessel 10 through the feed port 11; the evaporator 20 is started, and the evaporator 20 heats the distilled water inside to generate steam. When the steam in the inlet pipe 21 accumulates to a certain pressure, the high-pressure valve 22 is opened, and the steam is injected into the inlet chamber 14 from the jet port 23 and acts on the fan blades 15. After being acted on by the steam, the fan blades 15 drive the stirring shaft 70 to rotate, so that the stirring blades 71 on the stirring shaft 70 continuously stir the Curcuma zedoaria in the distillation vessel 10. At the same time, the steam acts on the Curcuma zedoaria through the outlet 13 and forms volatile oil; the volatile oil enters the condenser tower through the first pipe 30 and is condensed, and then fed into the fractionation tank for fractionation; the liquid obtained after fractionation is Curcuma zedoaria oil.

[0057] Example 2

[0058] This embodiment is largely the same as the above embodiments, except that this embodiment proposes a method for extracting Curcuma zedoaria oil, including the following steps:

[0059] Step 1: Add the pretreated Curcuma zedoaria into the distillation vessel 10 through the feed inlet 11;

[0060] Step 2: Start the evaporator 20. The evaporator 20 heats the distilled water inside to generate steam. When the steam in the inlet pipe 21 accumulates to a certain pressure, the high-pressure valve 22 opens. The steam is injected into the inlet chamber 14 from the jet nozzle 23 and acts on the fan blades 15. The fan blades 15 are driven by the steam to rotate the stirring shaft 70, so that the stirring blades 71 on the stirring shaft 70 continuously stir the turmeric in the distillation kettle 10. At the same time, the steam acts on the turmeric through the outlet 13 and forms volatile oil.

[0061] Step 3: The volatile oil enters the condenser tower through the first pipe 30 and is then condensed. It is then fed into the fractionation tank for fractionation. The liquid obtained after fractionation is Curcuma zedoaria oil.

[0062] In this embodiment, the pretreatment includes slicing the pretreated Curcuma zedoaria, and then sieving the slices through a 24-mesh sieve.

[0063] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this invention does not involve any improvement to the software and methods.
