Description

Technical Field

[0001] The present invention relates to the pharmaceutical field, and particularly to an apparatus for preparing volatile oil inclusion compound and a method for preparing volatile oil inclusion compound. Background Art

[0002] Volatile components are components in traditional Chinese medicine with various physiological functions. The volatile oil of traditional Chinese medicine is divided into two types. One is volatile oil with a relative density below 1.0 (referred to as light oil for short), and the other is volatile oil with a relative density above 1.0 (referred to as heavy oil for short). Currently, it is mainly collected by steam distillation method. Since the relative density of light oil is lighter than that of water, it is relatively easy to separate from water and be collected, and the yield is relatively high; while heavy oil is slightly heavier than water and is often easily emulsified in water. The amount of heavy oil separated by static stratification is small, and the yield is low. Moreover, the existing apparatus for preparing volatile oil inclusion compound cannot simultaneously collect light oil and heavy oil, and often different apparatuses are required for collection, which not only increases equipment investment but also increases the floor area of the equipment.

[0003] Currently, the technology for extracting and collecting volatile oil is to continuously collect the distilled oil-water mixture within a set distillation time. After the distillation is completed, it is left standing for a period of time. After the oil and water are stratified, the volatile oil is collected separately, and an appropriate amount of inclusion auxiliary is added to the collected volatile oil for inclusion. In the above operations, the collection and inclusion of volatile oil are segmented operations, the processes are not connected, the production efficiency is low, the loss of volatile oil is large, and during the inclusion process, the dosing of the inclusion agent is unreasonable, resulting in poor composition of the prepared volatile oil inclusion compound. Summary of the Invention

[0004] Based on this, the present invention aims to overcome the defects of low yield in the extraction of volatile oil in the prior art, inability to simultaneously collect light oil and heavy oil, unconnected processes, low production efficiency, large loss of volatile oil, and unreasonable dosing of the inclusion agent during the inclusion process, resulting in poor composition of the prepared volatile oil inclusion compound, and provides an apparatus for preparing volatile oil inclusion compound and a method for preparing volatile oil inclusion compound.

[0005] The technical solution is as follows:

[0006] The present technical solution provides an apparatus for preparing volatile oil inclusion compound, including:

[0007] An extraction tank for putting in the medicinal materials to be extracted and distilling the medicinal materials;

[0008] A condenser, communicated with the extraction tank and used for condensing volatile oil and aromatic water;

[0009] An oil-water separator, the number of the oil-water separators being at least three, and at least three oil-water separators being in openable and closable communication with the condenser; the oil-water separator includes a separation container, a first discharge port provided at the bottom of the separation container, and a second discharge port provided at the top or side wall of the separation container; the first discharge port is in openable and closable communication with the extraction tank through a first discharge pipeline, and the second discharge port is in openable and closable communication with the extraction tank through a second discharge pipeline;

[0010] An inclusion mechanism, which is in openable and closable communication with the oil-water separator.

[0011] The volatile oil inclusion preparation device of the present technical solution can be used to collect heavy oil and also to collect light oil, so that one device can meet multiple needs. Moreover, the volatile oil inclusion preparation device of the present technical solution seamlessly connects the collection process and the inclusion process, and the collection work can also be carried out simultaneously during the inclusion process, which not only improves production efficiency but also avoids the loss of volatile oil. And during the inclusion process, different doses of the clathrating agent can be added according to different collection situations, so that when the total dose of the clathrating agent added is certain, the composition of the volatile oil inclusion prepared by the present technical solution is optimal.

[0012] Specifically, when using the volatile oil inclusion preparation device of this technical solution, the medicinal materials are put into the extraction tank, and steam is introduced into the extraction tank for distillation. The steam drives the volatile oil and aromatic water in the extraction tank into the condenser for condensation. The condensed volatile oil and aromatic water enter the first oil-water separator. After the first oil-water separator collects a specified amount of volatile oil and aromatic water, the condenser is switched to communicate with the second oil-water separator to collect the volatile oil and aromatic water. After the second oil-water separator collects a specified amount of volatile oil and aromatic water, the condenser is switched to communicate with the third oil-water separator to collect the volatile oil and aromatic water. And so on, repeating the above collection steps until the preset Nth oil-water separator participates in the collection of volatile oil and aromatic water. And when the third oil-water separator collects the volatile oil and aromatic water, the first oil-water separator is connected to the inclusion mechanism, and the first-stage inclusion agent is put in for the first-stage inclusion. After the first-stage inclusion is completed, the inclusion mechanism is switched to communicate with the second oil-water separator, and the second-stage inclusion agent is put in for the second-stage inclusion. After the second-stage inclusion is completed, the inclusion mechanism is switched to communicate with the third oil-water separator, and the third-stage inclusion agent is put in for the third-stage inclusion. Repeat the above inclusion steps until the preset Nth-stage inclusion is completed. Therefore, the volatile oil inclusion preparation device of this technical solution collects the volatile oil in a seamless connection by setting at least three oil-water separators. When the third oil-water separator collects the volatile oil, the first oil-water separator has already completed the oil-water separation and can be connected to the inclusion mechanism for the inclusion process. And so on, thus greatly improving the oil collection efficiency, enabling the collection work to be carried out simultaneously during the inclusion process, improving the production efficiency and avoiding the loss of volatile oil.

[0013] Moreover, since this technical solution is provided with at least three oil-water separators, at least three-stage oil-water separation collection and at least three-stage inclusion processes are carried out. Due to the hierarchical collection, different dosages of inclusion agents can be put in during the hierarchical inclusion, making the composition of the prepared volatile oil inclusion better. For example, when carrying out the first-stage inclusion, since the concentration of the first-stage volatile oil collected is relatively high and the purity is good, a relatively large dosage of the inclusion agent is put in for inclusion to improve the inclusion effect. Similarly, when carrying out the second-stage inclusion, since the concentration of the second-stage volatile oil is lower than that of the first-stage volatile oil, the dosage of the inclusion agent put in is less than that in the first-stage inclusion. And so on until all inclusions are completed. The hierarchical collection and hierarchical inclusion of this technical solution can put in different inclusion agents according to different situations. Under the condition that the total amount of the inclusion agent used is the same, compared with the traditional method of putting all the inclusion agents into all the volatile oils at one time, the hierarchical inclusion of this technical solution makes the inclusion more perfect.

[0014] Moreover, since the first discharge port and the second discharge port are designed in this technical solution, when the density of the volatile oil is greater than that of water, that is, when the volatile oil is heavy oil, before the oil-water separators are connected to the inclusion mechanism, the second discharge pipeline can be selectively opened to connect the second discharge port to the extraction tank, and the excess water is discharged before inclusion. Similarly, when the density of the volatile oil is less than that of water, that is, when the volatile oil is light oil, before the oil-water separators are connected to the inclusion mechanism, the first discharge pipeline can be selectively opened to connect the first discharge port to the extraction tank, and the excess water is discharged before inclusion. This enables the oil-water separator of this technical solution to be used not only for the collection of light oil but also for the collection of heavy oil, so that one device can meet multiple requirements.

[0015] In one embodiment, a first flowmeter is provided on the connecting pipeline between the oil-water separator and the condenser.

The inclusion tank is provided with a first inlet that is openably and closably connected to the oil-water separator, an inclusion outlet that is openably and closably connected to the grinding inlet, and a second inlet that is openably and closably connected to the grinding outlet.

[0023] In one embodiment, the volatile oil inclusion compound preparation device further includes a drying mechanism that is openably and closably connected to the inclusion mechanism.

[0024] In one embodiment, the volatile oil inclusion compound preparation device further includes a collection tank that is openably and communicably connected to the drying mechanism.

[0025] In one embodiment, the volatile oil inclusion compound preparation device further includes a mixing mechanism that is openably and communicably connected to the collection tank.

[0027] In one embodiment, the volatile oil inclusion compound preparation device further includes a screening mechanism that is openably and communicably connected to the mixing mechanism.

[0028] In one embodiment, a second feeding machine is provided on the communication pipeline between the mixing mechanism and the screening mechanism.

[0029] In one embodiment, the volatile oil inclusion compound preparation device further includes a temporary storage tank that is openably and communicably connected to the screening mechanism.

[0030] In one embodiment, the volatile oil inclusion compound preparation device further includes a controller that is electrically connected to the condenser, the oil-water separator, and the inclusion mechanism, and is used to control the start and stop of the condenser and the inclusion mechanism, and to control the communication relationship between the condenser, the oil-water separator, and the inclusion mechanism.

[0031] This technical solution also provides a method for preparing a volatile oil inclusion compound, including the following steps:

[0032] Put the medicinal materials to be extracted into the extraction tank and distill them by passing in steam;

[0033] The steam drives the volatile oil and aromatic water in the extraction tank into the condenser for condensation;

[0034] The condensed volatile oil and aromatic water enter the first oil-water separator;

[0035] After the first oil-water separator collects a specified amount of volatile oil and aromatic water, switch the condenser to communicate with the second oil-water separator to collect the volatile oil and aromatic water;

[0041] Repeat the above inclusion steps until the Nth-stage inclusion is completed;

[0042] The dosage of the Mth-stage inclusion agent is greater than that of the (M + 1)th-stage inclusion agent;

[0043] Wherein, N ≥ 3, N > M ≥ 1.

[0044] The volatile oil clathrate preparation device of this technical solution seamlessly connects the collection process and the inclusion process. During the inclusion process, the collection work can also be carried out simultaneously, which not only improves production efficiency but also avoids the loss of volatile oil. And during the inclusion process, different dosages of inclusion agents are added according to different collection situations. Thus, when the total dosage of the inclusion agent is certain, the composition of the volatile oil clathrate prepared by this technical solution is optimal.

[0045] The volatile oil clathrate preparation device of this technical solution conducts seamless volatile oil collection work by setting at least three oil-water separators. When the third oil-water separator collects the volatile oil and aromatic water, the first oil-water separator has already completed the oil-water separation and can be connected to the inclusion mechanism for the inclusion process, and so on. Therefore, the oil collection efficiency is greatly improved, and the collection work can also be carried out simultaneously during the inclusion process, which not only improves production efficiency but also avoids the loss of volatile oil. And during the inclusion process, different dosages of inclusion agents are added according to different collection situations. The dosage of the Mth-stage inclusion agent is greater than that of the (M + 1)th-stage inclusion agent, that is, when the volatile oil or oil-water mixture collected by the oil-water separator connected to the condenser first is included, the dosage of the inclusion agent input is always greater than that of the oil-water separator connected to the condenser later. The hierarchical collection and hierarchical inclusion of this technical solution add different inclusion agents according to different situations. Compared with the traditional method of adding all the inclusion agents to all the volatile oils at one time when the total amount of the inclusion agent used is the same, the hierarchical inclusion of this technical solution makes the inclusion more perfect.

[0046] In one embodiment, the dosage of the first-stage complexing agent is 60%-80% of the total dosage of the complexing agent; and / or the dosage of the second-stage complexing agent is 20%-40% of the total dosage of the complexing agent; and / or the dosage of the third-stage complexing agent is 10%-20% of the total dosage of the complexing agent.

[0047] In one embodiment, the dosage of the first-stage complexing agent is a, and the dosage range of the m-th stage complexing agent is a / (m + 1) to a / m, where m ≥ 1.

[0048] In one embodiment, when the density of the volatile oil is greater than that of water, before each oil-water separator is connected to the complexing mechanism, the second discharge pipeline can be selectively opened to connect the second discharge port to the extraction tank to discharge excess water; or, when the density of the volatile oil is less than that of water, before each oil-water separator is connected to the complexing mechanism, the first discharge pipeline can be selectively opened to connect the first discharge port to the extraction tank to discharge excess water.

Detailed implementation manners

[0056] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0057] As Figure 1 shown, this implementation manner provides a volatile oil inclusion preparation device, including: an extraction tank 10 for putting the medicinal materials to be extracted and distilling the medicinal materials; a condenser 20 communicated with the extraction tank 10 and used for condensing volatile oil and aromatic water; an oil-water separator 30, the number of the oil-water separators 30 being at least three, and at least three oil-water separators 30 being openably and closably communicated with the condenser 20; the oil-water separator 30 includes a separation container 33, a first discharge port 31 provided at the bottom of the separation container 33, and a second discharge port 32 provided at the top or side wall of the separation container 33. In this implementation manner, the second discharge port 32 is provided at the side wall of the separation container 33 and near the top; the first discharge port 31 is communicated with the extraction tank 10 through an openable and closable first discharge pipeline, and the second discharge port 32 is communicated with the extraction tank 10 through an openable and closable second discharge pipeline; an inclusion mechanism 40, openably and closably communicated with the oil-water separator 30.

[0058] The volatile oil inclusion preparation device of this embodiment can be used to collect heavy oil and light oil, so that one device can meet various needs. Moreover, the volatile oil inclusion preparation device of this embodiment seamlessly connects the collection process and the inclusion process, and the collection work can also be carried out simultaneously during the inclusion process, which not only improves production efficiency but also avoids the loss of volatile oil. And during the inclusion process, different dosages of the clathrating agent can be added according to different collection situations. Therefore, when the total dosage of the clathrating agent added is certain, the composition of the volatile oil inclusion prepared by this technical solution is optimal.

[0059] Specifically, when using the volatile oil inclusion preparation device of this embodiment, the medicinal materials are put into the extraction tank 10, and steam is introduced into the extraction tank 10 for distillation. The steam drives the volatile oil and aromatic water in the extraction tank 10 into the condenser 20 for condensation, and the condensed volatile oil and aromatic water enter the first oil-water separator 30; after the first oil-water separator 30 collects a specified amount of volatile oil and aromatic water, the condenser 20 is switched to communicate with the second oil-water separator 30 to collect the volatile oil and aromatic water; after the second oil-water separator 30 collects a specified amount of volatile oil and aromatic water, the condenser 20 is switched to communicate with the third oil-water separator 30 to collect the volatile oil and aromatic water; and so on, repeating the above collection steps until the preset Nth oil-water separator 30 participates in the collection of volatile oil and aromatic water. And when the third oil-water separator 30 collects the volatile oil and aromatic water, the first oil-water separator 30 is connected to the inclusion mechanism 40, and the first-stage clathrating agent is added for the first-stage inclusion; after the first-stage inclusion is completed, the inclusion mechanism 40 is switched to communicate with the second oil-water separator 30, and the second-stage clathrating agent is added for the second-stage inclusion; after the second-stage inclusion is completed, the inclusion mechanism 40 is switched to communicate with the third oil-water separator 30, and the third-stage clathrating agent is added for the third-stage inclusion; repeating the above inclusion steps until the preset Nth-stage inclusion is completed; Therefore, the volatile oil inclusion preparation device of this embodiment collects the volatile oil in a seamless connection by setting at least three oil-water separators 30. When the third oil-water separator 30 collects the volatile oil and aromatic water, the first oil-water separator 30 has already completed the oil-water separation and can be connected to the inclusion mechanism 40 for the inclusion process, and so on. Therefore, the oil collection efficiency is greatly improved, and the collection work can also be carried out simultaneously during the inclusion process, which not only improves production efficiency but also avoids the loss of volatile oil.

[0060] Moreover, since at least three oil-water separators 30 are provided in this embodiment, at least three-stage oil-water separation and collection and at least three-stage inclusion processes are performed. Due to the hierarchical collection, different dosages of the clathrating agent can be added during hierarchical inclusion, making the components of the volatile oil clathrate better. For example, when performing the first-stage inclusion, since the concentration of the first-stage volatile oil collected is high and the purity is good, a larger dosage of the clathrating agent is added for inclusion to improve the inclusion effect. Similarly, when performing the second-stage inclusion, since the concentration of the second-stage volatile oil collected is lower than that of the first-stage volatile oil, the dosage of the clathrating agent added is less than that added during the first-stage inclusion, and so on until all inclusions are completed. The hierarchical collection and hierarchical inclusion of this embodiment can add different clathrating agents according to different situations. Under the condition that the total amount of the clathrating agent used is the same, compared with the traditional method of adding all the clathrating agent to all the volatile oil at one time, the hierarchical inclusion of this embodiment makes the inclusion more perfect.

[0061] Moreover, since the first discharge port 31 and the second discharge port 32 are designed in this embodiment, when the density of the volatile oil is greater than the density of water, that is, when the volatile oil is heavy oil, before each oil-water separator 30 is connected to the inclusion mechanism 40, the second discharge pipeline can be selectively opened to connect the second discharge port 32 to the extraction tank 10 to discharge the excess water before inclusion. Similarly, when the density of the volatile oil is less than the density of water, that is, when the volatile oil is light oil, before each oil-water separator 30 is connected to the inclusion mechanism 40, the first discharge pipeline can be selectively opened to connect the first discharge port 31 to the extraction tank 10 to discharge the excess water before inclusion. This enables the oil-water separator 30 of this embodiment to be used not only for the collection of light oil but also for the collection of heavy oil, so that one device can meet multiple requirements.

[0062] Hereinafter, this embodiment will be described by taking three oil-water separators 30 as an example. In other embodiments, the number of oil-water separators 30 can be increased as appropriate. For example, if the required collection amount is not reached after the three oil-water separators 30 have completed collection, a fourth oil-water separator 30 can be added for the collection and inclusion of the fourth-stage volatile oil or oil-water mixture, etc.

[0063] A first flowmeter 50 is provided on the connecting pipeline between the oil-water separator 30 and the condenser 20 of this embodiment. The first flowmeter 50 can measure the flow rate of the condensate flowing from the condenser 20 into the oil-water separator 30, so as to control the amount of the volatile oil and the oil-water mixture flowing into the oil-water separator 30. When the condenser 20 is connected to the first oil-water separator 30 and the flow rate monitored by the first flowmeter 50 reaches the preset flow rate, the condenser 20 is switched to be connected to the second oil-water separator 30, and so on, to make the storage amount in each oil-water separator 30 optimal, neither wasting the capacity nor causing overflow and other phenomena.

[0064] Specifically, the condenser 20 of this embodiment is connected to three oil-water separators 30 through a four-way pipe. The oil outlet of the condenser 20 is connected to the first interface of the four-way pipe through an oil outlet main pipe, and the first flowmeter 50 is arranged on the oil outlet main pipe; the second interface of the four-way pipe is connected to the first oil-water separator 30 through a first oil outlet pipe, and a first oil outlet valve 61 for controlling on / off is arranged on the first oil outlet pipe; the third interface of the four-way pipe is connected to the second oil-water separator 30 through a second oil outlet pipe, and a second oil outlet valve 62 for controlling on / off is arranged on the second oil outlet pipe; the fourth interface of the four-way pipe is connected to the third oil-water separator 30 through a third oil outlet pipe, and a third oil outlet valve 63 for controlling on / off is arranged on the third oil outlet pipe. When using the first oil-water separator 30 to collect volatile oil and oil-water mixture, open the first oil outlet valve 61 and close the second oil outlet valve 62 and the third oil outlet valve 63; when it is necessary to switch to the connection between the second oil-water separator 30 and the condenser 20, then close the first oil outlet valve 61 and the third oil outlet valve 63 and open the second oil outlet valve 62; when it is necessary to switch to the connection between the third oil-water separator 30 and the condenser 20, then close the first oil outlet valve 61 and the second oil outlet valve 62 and open the third oil outlet valve 63.

[0065] The condenser 20 can be placed horizontally or vertically.

[0066] The volatile oil clathrate preparation device of this embodiment further includes a total discharge pipe. The first discharge pipeline and the second discharge pipeline converge at the first end of the total discharge pipe, and the second end of the total discharge pipe is connected to the extraction tank 10; the second end of the total discharge pipe is the end opposite to the first end of the total discharge pipe; a second flowmeter is arranged on the total discharge pipe, and the second flowmeter is used to measure the amount of volatile oil entering the clathration mechanism 40 from the oil-water separator 30, making the flow easier to control.

[0067] Specifically, since there are three oil-water separators 30 in this embodiment, for the convenience of pipeline design, connection and saving the number of second flowmeters, in this embodiment, the first discharge pipes and the second discharge pipes of the three oil-water separators are all converged on the same total discharge pipe, saving the number of total discharge pipes and second flowmeters, and making the pipeline more concise. A first discharge valve is arranged near the first discharge port 31 of the first discharge pipe for controlling the on / off of the first discharge pipe, and a second discharge valve is arranged near the second discharge port 32 of the second discharge pipe for controlling the on / off of the second discharge pipe. When the collected volatile oil is heavy oil, then open the second discharge valve to discharge the water stratified at the top to the extraction tank 10. When the collected volatile oil is light oil, then open the first discharge valve to discharge the water stratified at the bottom to the extraction tank 10.

[0068] ​A sight glass for observing the situation inside the separation container 33 is provided on the wall surface of the separation container 33 described in this embodiment. Through the sight glass, the liquid level and the stratification situation of the collected liquid can be observed, etc., and the operation of the volatile oil clathrate preparation device in this embodiment can be better controlled by observing the situation. Specifically, the sight glass is a transparent heat-resistant tempered glass embedded in the separation container 33.

[0069] Since the clathration process also needs to be carried out in this embodiment and the clathration mechanism 40 also needs to be connected to the oil-water separator 30, in order to make the pipeline simple, in this embodiment, the extraction tank 10 is connected to the second end of the main discharge pipe through an openable and closable recovery branch 64; the clathration mechanism 40 is connected to the second end of the main discharge pipe through an openable and closable clathration branch 65. When water recovery is required, the corresponding first discharge valve or second discharge valve and the recovery branch 64 are opened to recover the water into the extraction tank 10. When the clathration of volatile oil is required, the first discharge valve and the clathration branch 65 are opened to transport all the collected liquid that has been subjected to oil-water recovery in the separation container 33 to the clathration mechanism 40. Since the first discharge port 31 is located at the bottom of the separation container 33, when discharging the collected liquid to the clathration mechanism 40, it can be discharged as much as possible.

[0070] In order to make the water recovery efficiency and the transportation efficiency of the collected liquid higher and the power stronger, a three-way pump 70 is provided at the second end of the main discharge pipe described in this embodiment. The liquid inlet of the three-way pump 70 is connected to the main discharge pipe, the first liquid outlet of the three-way pump 70 is connected to the recovery branch 64, and the second liquid outlet of the three-way pump 70 is connected to the clathration branch 65.

[0071] A first recovery valve 641 is provided at one end of the recovery branch 64 close to the three-way pump 70 to control the on-off of the recovery branch 64 through the first recovery valve 641; a first clathration valve 651 is provided at one end of the clathration branch 65 close to the three-way pump 70 to control the on-off of the clathration branch 65 through the first clathration valve 651. Since the first recovery valve 641 and the first clathration valve 651 in this embodiment are both arranged close to the three-way pump 70, when the recovery branch 64 is opened and the clathration branch 65 is closed, the water will not be diverted into the clathration branch 65. Similarly, when the clathration branch 65 is opened and the recovery branch 64 is closed, the collected liquid will not be diverted into the recovery branch 64, avoiding waste. Moreover, a second recovery valve is also provided at one end of the recovery branch 64 close to the extraction tank 10 and is used in cooperation with the first recovery valve 641 to make the on-off control of the recovery branch 64 better. Similarly, a second clathration valve is also provided at a section of the clathration branch 65 close to the clathration mechanism 40.

[0072] The inclusion mechanism 40 in this embodiment includes an inclusion tank 41 that is openably and closably connected to the oil-water separator 30, and a grinder 42 that is openably and closably connected to the inclusion tank 41. The inclusion branch 65 is connected to the inclusion tank 41 and is used to directly receive the collected liquid from the oil-water separator 30. When inclusion is performed, an inclusion agent is put into the second inlet 412 of the inclusion tank 41, and the collected liquid and the inclusion agent are stirred by the stirring paddle in the inclusion tank 41 to complete the stirring inclusion. Moreover, in order to improve the inclusion effect in this embodiment, the inclusion liquid after being stirred and included in the inclusion tank 41 is ground and included by the grinder 42.

[0073] Specifically, the stirring in the inclusion tank 41 and the grinding in the grinder 42 in this embodiment are performed in a cyclic inclusion manner. The grinder 42 is provided with a grinding inlet 421 and a grinding outlet 422. The inclusion tank 41 is provided with a first inlet that is openably and closably connected to the oil-water separator 30, an inclusion outlet 411 that is openably and closably connected to the grinding inlet 421, and a second inlet 412 that is openably and closably connected to the grinding outlet 422. That is, the first inlet is connected to the inclusion branch 65. The inclusion tank 41 receives the collected liquid from the oil-water separator 30. An inclusion agent is put into the second inlet 412, and the stirring is performed by the stirring paddle in the inclusion tank 41. After stirring for a predetermined time, the inclusion outlet 411 is opened, so that the stirred inclusion liquid enters the grinder 42 through the grinding inlet 421 for grinding. The ground inclusion liquid is then transported through the grinding outlet 422 to the second inlet 412 and enters the inclusion tank 41 for stirring, and so on in a cycle. Until the cycle time reaches the preset time, the inclusion is completed. In this embodiment, the cycle time is set to 3 hours. When 3 hours are reached, the inclusion is completed, and the next process can be entered.

[0074] A third flowmeter and a liquid pump are provided on the pipeline connecting the inclusion outlet 411 and the grinding inlet 421 in this embodiment, which are convenient for measuring and controlling the flow rate and providing power.

[0075] As Figure 2 shown, in order to enable the volatile oil inclusion compound preparation device in this embodiment to integrate more functions and further shorten the entire extraction and inclusion time of the volatile oil, the volatile oil inclusion compound preparation device further includes a drying mechanism 80 that is openably and closably connected to the inclusion mechanism 40. After the inclusion process is completed, the included inclusion liquid can be directly dried to reduce pollution. Moreover, when the first-stage inclusion liquid is being dried, the inclusion of the second-stage volatile oil and the oil-water mixture in the second oil-water separator can be performed synchronously, saving time and improving efficiency.

[0076] Specifically, the drying mechanism 80 is connected to the outlet of the inclusion tank 41. Since the grinding inlet 421 is also connected to the inclusion outlet 411, a three-way pipe can be used to connect the drying mechanism 80, the inclusion tank 41, and the grinder 42. The drying mechanism 80 can be one or a combination of spray drying, vacuum drying, freeze drying, and belt drying.

[0077] The volatile oil inclusion preparation device of this embodiment further includes a collection tank 90 that is openably and closably communicated with the drying mechanism 80. Specifically, an openable and closable powder outlet 81 is provided at the bottom of the drying mechanism 80, and the collection tank 90 is provided with a powder inlet 91. The powder outlet 81 and the powder inlet 91 are connected by a pipeline, and a powder inlet valve is provided on the pipeline. After the drying mechanism 80 finishes drying the inclusion liquid to form an inclusion intermediate product, the powder outlet 81 and the powder inlet valve are opened to transport the dried inclusion to the collection tank 90 to obtain the inclusion intermediate product.

[0078] To enable the volatile oil inclusion preparation device of this embodiment to integrate more functions, further shorten the entire extraction time of the volatile oil, and improve the uniformity of the inclusion intermediate product, the volatile oil inclusion preparation device further includes a mixing mechanism 100 that is openably and closably communicated with the collection tank 90. Since the drying mechanism 80 only dries the inclusion liquid without a mixing function, it may result in poor uniformity of the inclusion intermediate product. Therefore, in this embodiment, the mixing mechanism 100 is used to mix the inclusion intermediate products collected at each stage separately to make the inclusion intermediate products at each stage more uniform.

[0079] The mixing mechanism 100 can be one or a combination of a square cone mixer, a V-type mixer, a double cone mixer, a three-dimensional mixer, and a double spiral conical mixer.

[0080] Specifically, a first feeding machine 110 is provided on the communication pipeline between the mixing mechanism 100 and the collection tank 90. The inclusion intermediate product in the collection tank 90 is transported to the mixing mechanism 100 through the first feeding machine 110 for mixing. The first feeding machine 110 is a vacuum feeding machine.

[0081] The volatile oil inclusion preparation device of this embodiment further includes a screening mechanism 120 that is openably and closably communicated with the mixing mechanism 100, so as to remove impurities from the inclusion intermediate product after mixing and ensure the purity of the inclusion. The screening mechanism 120 is a vibrating screen.

[0082] Specifically, a second feeding machine 130 is provided on the communication pipeline between the mixing mechanism 100 and the screening mechanism 120. The mixture product in the mixing mechanism 100 is transported to the screening mechanism 120 through the second feeding machine 130 to remove impurities. The second feeding machine 130 is a vacuum feeding machine.

[0083] Moreover, in order not to restrict the operation of the mixing mechanism 100, when the mixing mechanism 100 is mixing, the connection between the mixing mechanism 100 and the first feeding machine 110 and the second feeding machine 130 is released, so that the mixing mechanism 100 can be turned over or mixed in other forms without being restricted by the connecting pipelines.

[0084] The volatile oil inclusion compound preparation device described in this embodiment further includes a temporary storage tank 140 that can be opened and closed in communication with the screening mechanism 120. The intermediate products after each stage of mixing are collected through the temporary storage tank 140. Taking this embodiment as an example, since there are three oil-water separators 30 in this embodiment, that is, three-stage collection and three-stage subsequent processes are carried out, three temporary storage tanks 140 are required in this embodiment to separately collect the intermediate products collected in the first stage, the second stage, and the third stage. Moreover, after the three stages are all collected, the intermediate products of the first stage, the second stage, and the third stage are all re-fed into the mixing mechanism 100 for total mixing of the inclusion compound to form the final product of the inclusion compound for use in the next preparation and formulation.

[0085] Since the three temporary storage tanks 140 need to separately collect the mixtures of the first stage, the second stage, and the third stage, in order to facilitate the replacement of the temporary storage tank 140, the temporary storage tank 140 in this embodiment is a movable tank body. Specifically, casters 141 for movement are provided on the temporary storage tank 140.

[0086] The volatile oil inclusion compound preparation device described in this embodiment further includes a controller (not shown in the figure) that is electrically connected to the condenser 20, the oil-water separator 30, the inclusion mechanism 40, the drying mechanism 80, the first feeding machine 110, the second feeding machine 130, the mixing mechanism 100, and the screening mechanism 120, and is used to control the start and stop of the condenser 20, the inclusion mechanism 40, the drying mechanism 80, the first feeding machine 110, the second feeding machine 130, the mixing mechanism 100, and the screening mechanism 120, and to control the communication relationship between the condenser 20, the oil-water separator 30, the inclusion mechanism 40, the drying mechanism 80, the first feeding machine 110, the second feeding machine 130, the mixing mechanism 100, and the screening mechanism 120. That is, parameters of each electrical equipment and each valve can be set through the terminal program, and then remotely controlled through the controller to realize the fully automated production of the volatile oil inclusion compound. The controller can be a background computer.

[0087] This embodiment also provides a method for preparing a volatile oil inclusion compound, including the following steps:

[0088] Put the medicinal materials to be extracted into the extraction tank 10 and introduce steam for distillation;

[0089] The steam drives the volatile oil and aromatic water in the extraction tank 10 into the condenser 20 for condensation;

[0090] The volatilized oil and aromatic water after condensation enter the first oil-water separator 30;

[0091] After the first oil-water separator 30 collects a specified amount of volatilized oil and aromatic water, the condenser 20 is switched to communicate with the second oil-water separator 30 to collect the volatilized oil and aromatic water;

[0092] After the second oil-water separator 30 collects a specified amount of volatilized oil and aromatic water, the condenser 20 is switched to communicate with the third oil-water separator 30 to collect the volatilized oil and aromatic water;

[0093] Repeat the above collection steps until the Nth oil-water separator 30 collects the volatilized oil and aromatic water;

[0094] When the third oil-water separator 30 collects the volatilized oil and aromatic water, the first oil-water separator 30 is communicated with the inclusion mechanism 40, and the first-stage inclusion agent is put in for the first-stage inclusion;

[0095] After the first-stage inclusion is completed, the inclusion mechanism 40 is switched to communicate with the second oil-water separator 30, and the second-stage inclusion agent is put in for the second-stage inclusion;

[0096] After the second-stage inclusion is completed, the inclusion mechanism 40 is switched to communicate with the third oil-water separator 30, and the third-stage inclusion agent is put in for the third-stage inclusion;

[0097] Repeat the above inclusion steps until the Nth-stage inclusion is completed;

[0098] The dosage of the Mth-stage inclusion agent is greater than that of the (M + 1)th-stage inclusion agent

[0099] Wherein, N≥3, N>M≥1.

[0100] The volatilized oil inclusion preparation device of this embodiment seamlessly connects the collection process and the inclusion process, and the collection work can also be carried out simultaneously during the inclusion process, which not only improves the production efficiency but also avoids the loss of volatilized oil. And during the inclusion process, different dosages of inclusion agents are put in according to different collection situations, so that when the total dosage of the inclusion agent put in is certain, the composition of the volatilized oil inclusion prepared by this embodiment is the best.

[0101] The volatile oil inclusion preparation device of this embodiment conducts seamless volatile oil collection by setting at least three oil-water separators 30. When the third oil-water separator 30 collects volatile oil and aromatic water, the first oil-water separator 30 has already completed oil-water separation and can be connected to the inclusion mechanism 40 for the inclusion process, and so on. Therefore, the oil collection efficiency is greatly improved, enabling the collection work to be carried out simultaneously during the inclusion process, which not only improves production efficiency but also avoids the loss of volatile oil. And during the inclusion process, different dosages of the inclusion agent are put in according to different collection situations. The dosage of the inclusion agent at the Mth level is greater than that at the (M + 1)th level, that is, when the volatile oil or oil-water mixture collected by the oil-water separator 30 connected to the condenser 20 first is included, the dosage of the inclusion agent put in is always greater than that of the oil-water separator 30 connected to the condenser 20 later. The hierarchical collection and hierarchical inclusion of this embodiment put in different inclusion agents according to different situations. In the case of the same total amount of inclusion agent used, compared with the traditional method of putting all the inclusion agent into all the volatile oil and aromatic water at one time, the hierarchical inclusion of this embodiment makes the inclusion more perfect.

[0102] Taking the three-level inclusion as an example in this embodiment, when the total dosage of the inclusion agent is determined, the dosage of the inclusion agent at the first level in this embodiment is 60%-80% of the total dosage of the inclusion agent; the dosage of the inclusion agent at the second level is 20%-40% of the total dosage of the inclusion agent; the dosage of the inclusion agent at the third level is 10%-20% of the total dosage of the inclusion agent.

[0103] In other embodiments, whether the total dosage of the inclusion agent is uncertain or determined, the following method can be used for hierarchical dosing of the inclusion agent. When the dosage of the inclusion agent at the first level is a, the dosage range of the inclusion agent at the mth level is a / (m + 1) to a / m, where m≥1.

[0104] Since this embodiment is provided with a first discharge port 31 and a second discharge port 32, the excess liquid can be recovered before inclusion. When the density of the volatile oil is greater than that of water, before the oil-water separator 30 is connected to the inclusion mechanism 40, the second discharge pipeline can be selectively opened to connect the second discharge port 32 to the extraction tank 10 to discharge the excess water; or, when the density of the volatile oil is less than that of water, before the oil-water separator 30 is connected to the inclusion mechanism 40, the first discharge pipeline can be selectively opened to connect the first discharge port 31 to the extraction tank 10 to discharge the excess water.

[0105] In one embodiment, when the density of the volatile oil is greater than that of water, before the second to the Nth oil-water separators 30 are connected to the inclusion mechanism 40, the second discharge pipeline is opened to connect the second discharge port 32 to the extraction tank 10 to discharge the excess water; or, when the density of the volatile oil is less than that of water, before the second to the Nth oil-water separators 30 are connected to the inclusion mechanism 40, the first discharge pipeline is opened to connect the first discharge port 31 to the extraction tank 10 to discharge the excess water.

[0106] Specifically, in this embodiment, the first oil-water separator 30 serves as a container for the first-stage oil-water separation and collection. Since the concentration of the volatile oil is relatively high and the amount of excess liquid is relatively small in the first-stage oil-water separation, the excess liquid does not need to be recycled before inclusion. Instead, the collected volatile oil and the oil-water mixture are directly transported to the inclusion mechanism 40 for inclusion after collection. When the second oil-water separator 30 and the third oil-water separator 30 collect the volatile oil and the aromatic water, the concentration of the volatile oil is lower than that in the first-stage collection at this time. Therefore, after standing and stratifying, the excess water can be passed into the extraction tank 10 for recycling by opening the first discharge port 31 or the second discharge port 32 to improve the yield of the volatile oil at this stage.
