[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] The present application will be further described in detail below with reference to the accompanying drawings.

[0043] This application discloses a novel steam distillation apparatus for extracting plant essential oils.

[0044] like Figure 1 and Figure 2 As shown, a novel steam distillation apparatus for extracting plant essential oils includes a heating element 1, a storage container 2, a storage cover 5, a condenser 3, and a receiving component 4. The heating element 1 has a heating space for containing distilled water; the storage container 2 has a storage space for containing the material to be extracted (which, after distillation, yields plant essential oils). The storage container 2 is cylindrical, with a first inlet hole at one end communicating with the heating space, and a feeding port 21 at the other end; the storage cover 5 is detachably mounted on the storage container 2 and covers the feeding port 21; one end of the condenser 3 is connected to the storage cover 5, and a first connecting channel is formed within the condenser 3, with one end of the first connecting channel communicating with the storage space; one end of the receiving component 4 is connected to the other end of the condenser 3, and a receiving space is formed within the receiving component 4, with one end of the receiving space communicating with the other end of the first connecting channel.

[0045] The steam generated by heating the distilled water in the heating element 1 is introduced into the storage space in the storage container 2. The steam comes into contact with the material to be extracted and undergoes azeotropy. The azeotropic steam is condensed by the condensing component 3 to obtain the distillate, which is finally collected by the receiving component 4.

[0046] This application adopts a design that separates the extractable material from distilled water, which not only avoids the occurrence of boiling but also prevents the heat-sensitive components (such as terpenes) in the essential oil from undergoing pyrolysis or oxidative deterioration.

[0047] The cylindrical design of the storage container 2 facilitates full contact between water vapor and the material to be extracted, avoiding the phenomenon that the material to be extracted at the edges cannot come into contact with water vapor. Since the storage cover 5 covers the feeding port 21 of the storage container 2, it is only necessary to remove the storage cover 5 to easily extract the material to be extracted into the storage space. The operation is convenient and improves the overall extraction efficiency of the device.

[0048] Specifically, existing methods typically store the material to be extracted together with the water to be distilled in a spherical distillation flask. The spherical distillation flask has a spherical space inside, and the material to be extracted is filled into the flask through its opening. However, the opening of the existing spherical distillation flask and the space inside the sphere are quite different. To remove the material to be extracted from the space inside the sphere, it can only be poured out through the opening. During the pouring process, the material to be extracted will accumulate at the opening, making it very difficult to remove.

[0049] Meanwhile, because the existing spherical distillation flasks have very small openings, users cannot directly place the material to be extracted into the spherical space. Instead, they can only place the material at the opening and let it fall into the spherical space. To prevent the material from damaging the spherical distillation flask, the operator needs to carefully slide the material from the opening into the spherical space, which makes filling the material difficult and affects work efficiency.

[0050] In this patent application, the design of separating the extractable material from the distilled water avoids the occurrence of boiling and also avoids the decomposition and deterioration of the plant essential oil components caused by continuous heating.

[0051] Heating element 1 is a two-necked round-bottom flask. Heating element 1 has two necks, namely a first neck 11 and a second neck 12. The first neck 11 is connected to the first inlet hole, so that the heating space is connected to the storage space, which allows water vapor in the heating space to enter the storage space. The second neck 12 is blocked by a piston or other seals during the operation of the new steam distillation extraction device for plant essential oils. When it is necessary to fill the heating space with distilled water, the piston can be removed and distilled water can be added to the heating space through the second neck. The operation is convenient and improves the overall working efficiency of the new steam distillation extraction device for plant essential oils.

[0052] The storage space of the storage container 2 used to store the material to be extracted has the same shape as the outer shape of the storage container 2, which is cylindrical. The diameter of the storage space is greater than or equal to 55 mm and less than or equal to 55 mm.

[0053] In this embodiment, the diameter of the storage space is 60 mm, and the diameter of the feeding port 21 is 55 mm.

[0054] The first inlet hole and the feeding port 21 are located at both ends of the storage container 2. The first inlet hole can be inserted into the first diameter according to the diameter of the first diameter, thereby completing the assembly of the heating element 1 and the storage container 2.

[0055] When it is necessary to fill or remove the material to be extracted into the storage space, simply remove the storage cover 5 from the feeding port 21. Since the feeding port 21 has a large diameter, it can be easily inserted into the storage space to perform the extraction or filling operation.

[0056] Especially for the extraction of the material to be extracted, since the diameter of the feeding port 21 is almost the same as the diameter of the storage space and the storage space is cylindrical, it is very convenient to pour the material to be extracted out of the storage space or insert it into the storage space to extract the material to be extracted.

[0057] like Figure 2 As shown, a second connecting channel is formed inside the storage cover 5. A first guide port and a second guide port are respectively provided at both ends of the storage cover 5. Both the first guide port and the second guide port are connected to the second connecting channel. The first guide port is connected to the feeding port 21, and the second guide port is connected to the first connecting channel. The diameter of the first guide port is larger than the diameter of the second guide port.

[0058] Specifically, the first and second guide ports are arranged from bottom to top on the storage cover 5, and the first and second guide ports are respectively located at both ends of the second connecting channel.

[0059] Cover the storage cap 5 on top of the storage container 2. The storage cap 5 can completely cover the feeding port 21 to prevent azeotropic vapor from leaking from the feeding port 21.

[0060] When the storage cover 5 is closed on top of the storage container 2, the first guide port is connected to the feeding port 21, so that the storage space is connected to the second connecting channel, allowing the azeotropic vapor generated in the storage space to smoothly enter the second connecting channel and pass through the second guide port into the condensation component 3.

[0061] A frosted layer is provided at the connection between the storage cover 5 and the storage container 2.

[0062] Specifically, the frosted layer is set at the contact position between the storage cover 5 and the storage container 2. The frosted layer allows the storage cover 5 to fit tightly with the storage container 2, effectively preventing azeotropic vapor from leaking from the feed port 21.

[0063] In this embodiment, the feeding port 21 and the storage connection part 51 for connecting with the feeding port 21, which will be disclosed later, adopt a standard ground joint connection. The connection standard is based on the provisions of the national standard GB / T 21561-2008 "Interchangeable conical ground joints for laboratory glassware".

[0064] Using standard ground joints as specified by national standards not only ensures the reliability and interchangeability of the experiment, but also improves the efficiency and reduces maintenance costs.

[0065] It should be noted that the feeding port 21 and the storage connection part 51 are connected by a 55 / 50 specification ground joint and connector.

[0066] Wherein, 55 represents the diameter of the large end of the grinding port, in millimeters (mm); 50 represents the axial length of the conical surface of the grinding port, in millimeters (mm), that is, the length of the conical part from the large end to the small end of the grinding port is 50 millimeters; the feeding port 21 is the grinding port; and the material storage connection part 51 is the connector.

[0067] In addition, a frosted layer is provided at the connection between the heating element 1 and the storage container 2, the connection between the storage cover 5 and the condensing assembly 3, the connection of the internal structure of the condensing assembly 3, and the connection between the condensing assembly 3 and the receiving assembly 4, in order to improve the airtightness of the connection. It should be noted that the connection method is the same as the connection method of the feeding port 21 and the storage connection part 51, all of which adopt standard ground joint connection.

[0068] like Figure 1 and Figure 2 As shown, the storage cover 5 includes a storage connection part 51 and a condensation connection part 52, with the condensation connection part 52 disposed on the storage connection part 51; the second connecting channel includes a storage connecting channel and a condensation connecting channel; a storage connecting channel is formed inside the storage connection part 51, and a condensation connecting channel is formed inside the condensation connection part 52, the storage connecting channel and the condensation connecting channel are connected, a first guide port is provided at the end of the storage connecting channel away from the condensation connecting channel, and a second guide port is provided at the end of the condensation connecting channel away from the storage connecting channel; the storage connection part 51 is conical in shape, and the storage connection part 51 covers the storage container 2, with a standard sealing surface disposed on the inner wall of the storage connecting channel.

[0069] Specifically, the storage connection part 51 is tapered, and the first guide port is located at the end of the storage connection part 51 away from the condensation connection part 52.

[0070] The cross-sectional radius of the storage connection part 51 gradually increases from the end away from the condensation connection part 52 to the end closer to the condensation connection part 52. The cross-sectional radius of the end of the storage connection part 51 away from the condensation connection part 52 is smaller than the radius of the feeding port 21, while the cross-sectional radius of the end of the storage connection part 51 closer to the condensation connection part 52 is larger than the radius of the feeding port 21.

[0071] The storage connection part 51 can be inserted into the feeding port 21 to seal the feeding port 21 and prevent azeotropic vapor from leaking from the feeding port 21.

[0072] The frosted layer is set on the outer periphery of the storage connection part 51. The frosted layer is a standard ground joint sealing surface, which is closely fitted with the matching conical surface of the inner wall of the feeding port 21 to increase the airtightness of the storage connection part 51 and the storage device 2.

[0073] The second conduction port is provided at one end of the condensation connection part 52 away from the material storage connection part 51.

[0074] After the azeotropic vapor enters the material storage cover 5, it sequentially passes through the material storage communication channel and the condensation communication channel and then enters the first communication channel.

[0075] As Figure 1 shown, the new type of water vapor distillation plant essential oil extraction device includes a temperature measuring component 6, and the temperature measuring component 6 is provided on the condensation component 3; wherein, the detection part of the temperature measuring component 6 is in the first communication channel and close to the connection part of the first communication channel and the second communication channel, and the temperature measuring component 6 is used to detect the temperature of the azeotropic vapor just entering the first communication channel.

[0076] Specifically, the temperature measuring component 6 is a thermometer, and the detection end of the temperature measuring component 6 can extend into the first communication channel and be fixed at the position of the second conduction port. When the azeotropic vapor enters the first communication channel from the second conduction port for the first time, the real-time temperature of the azeotropic vapor can be detected by the temperature measuring component 6, so as to obtain accurate temperature data.

[0077] The setting of the temperature measuring component 6 can monitor the azeotropic point of the azeotropic vapor in real time, ensure the distillation efficiency, and prevent overheating decomposition or violent boiling.

[0078] As Figure 1 、 Figure 2 and Figure 3 shown, the condensation component 3 includes a distillation head 31 and a condenser tube 32; the first communication channel includes a first communication sub-channel and a second communication sub-channel. The first communication sub-channel is formed in the distillation head 31, and the second communication sub-channel is formed in the condenser tube 32. One end of the first communication sub-channel is connected to the second communication sub-channel, and the other end of the second communication sub-channel is connected to the receiving space; the distillation head 31 is respectively provided with a third conduction port and a fourth conduction port, both the third conduction port and the fourth conduction port are connected to the first communication sub-channel, the third conduction port is connected to the second conduction port, the temperature measuring component 6 is provided on the distillation head 31, and the detection part of the temperature measuring component 6 is in the first communication sub-channel and close to the third conduction port.

[0079] Specifically, the shape of the distillation head 31 is "卜" shaped. The distillation head 31 includes a temperature measuring insertion part 311 and a connection support part 312, and the connection support part 312 is provided on the side wall of the temperature measuring insertion part 311.

[0080] The first communication sub-channel includes a temperature measuring insertion sub-channel and a condensation connection sub-channel. The temperature measuring insertion sub-channel is formed in the temperature measuring insertion part 311, and the condensation connection sub-channel is formed in the connection support part 312.

[0081] The third conduction port and the fourth conduction port are respectively provided at both ends of the temperature measuring insertion part 311, and both the third conduction port and the fourth conduction port are connected to the temperature measuring insertion sub-channel.

[0082] A fifth through port is provided at the end of the connecting branch 312 away from the temperature measuring insertion part 311, and the fifth through port is connected to the condenser connection channel. The end of the connecting branch 312 away from the temperature measuring insertion part 311 is connected to the condenser tube 32, and the fifth through port is connected to the condenser connection channel and the second connection channel.

[0083] Temperature sensor 6 can be inserted into the temperature sensor insertion channel from the fourth through port, and the detection end of temperature sensor 6 is positioned near the third through port. In this way, when the azeotropic vapor enters the temperature sensor insertion channel from the second through port at the first moment, the real-time temperature of the azeotropic vapor can be detected by temperature sensor 6, thereby obtaining accurate temperature data.

[0084] It should be noted that the connection between the temperature measuring element 6 and the fourth conductive port is also a ground joint connection, which not only fixes the temperature measuring element 6 on the distillation head 31, but also prevents the azeotropic vapor from leaking to the outside through the fourth conductive port.

[0085] The azeotropic vapor is condensed by condenser 32 to obtain distillate, which is eventually collected by receiving component 4.

[0086] like Figure 1 and Figure 4 As shown, the receiving component 4 includes a receiving element 41 and a control switch 42. A receiving space is formed inside the receiving element 41, and a drain port is provided on the receiving element 41. The drain ports are all connected to the receiving space. The control switch 42 is provided on the receiving element 41 and is used to control the opening or closing of the drain ports.

[0087] Specifically, the receiver 41 includes a receiver body 411 and a neck 412, with the neck 412 positioned below the receiver body 411.

[0088] The receiving space includes a storage space and a discharge space. The receiving body 411 has a storage space, and the neck 412 has a discharge space. The storage space and the discharge space are connected.

[0089] The drain outlet is located at the end of the pipe neck 412 away from the receiving body 411, and the drain outlet is connected to the discharge space.

[0090] The control switch 42 is a plug valve, which is located on the neck 412. The control switch 42 can control the connection or closure of the storage space and the discharge space.

[0091] The azeotropic vapor of the distillate flows into the storage space from the first connecting channel and is stored. The control switch 42 is in the closed state to prevent the distillate from flowing into the discharge space and is finally discharged from the discharge port.

[0092] After settling, the distillate separates into layers in the receiving container 41. Due to the density difference, an upper organic phase and a lower aqueous phase are formed. Then, the control switch 42 is turned on, and the aqueous phase at the bottom flows into the discharge space and is discharged from the drain port. After all the aqueous phase has flowed out, the control switch 42 is turned off, and the organic phase can be retained in the storage space.

[0093] Furthermore, the receiving body 411 includes a first receiving part 4111 and a second receiving part 4112. Both the first receiving part 4111 and the second receiving part 4112 are cylindrical in shape. One end of the second receiving part 4112 is connected to the first receiving part 4111, and the other end is connected to the neck 412.

[0094] The storage space includes a first storage space and a second storage space. The first storage space is formed in the first receiving part 4111, and the second storage space is formed in the second receiving part 4112. The first storage space is connected to the first connecting channel and the second storage space, respectively, and the second storage space is connected to the discharge space.

[0095] The inner diameter of the first storage space is greater than or equal to 65 mm and less than or equal to 55 mm. In this embodiment, the inner diameter of the first storage space is 60 mm and the length is 80 mm. The first storage space can hold at least 125 ml of distillate.

[0096] The inner diameter of the second storage space is greater than or equal to 15 mm and less than or equal to 12 mm. In this embodiment, the inner diameter of the second storage space is 13 mm and the length is 1100 mm.

[0097] Since the amount of essential oil that can be extracted during the distillation extraction experiment using this application is very small, this application includes a first receiving part 4111 and a second receiving part 4112 in the receiving body 4111 to form a stepped structure. The diameters of the first storage space and the second storage space are designed to be small. The distillate can achieve a higher liquid level when placed in the receiving body 411 of this application, so that after the distillate is separated into layers, it is easier to control the control switch 42 to separate them.

[0098] like Figure 4 As shown, the receiver 41 is provided with a scale line 4112a, which is used to record the volume of plant essential oil received by the receiver 41.

[0099] Specifically, the scale line 4112a is set on the second receiving part 4112. The setting of the scale line 4112a makes it convenient for the operator to record the volume of the plant essential oil (organic phase) after liquid phase separation.

[0100] In summary, a novel steam distillation apparatus for extracting plant essential oils includes a heating element 1, a storage container 2, a storage cover 5, a condenser 3, and a receiving component 4. The heating element 1 contains a heating space for holding distilled water; the storage container 2 contains a storage space for holding the material to be extracted (which, after distillation, yields plant essential oils). The storage container 2 is cylindrical, with a first inlet hole at one end communicating with the heating space, and a feeding port 21 at the other end; the storage cover 5 is detachably mounted on the storage container 2 and covers the feeding port 21; one end of the condenser 3 is connected to the storage cover 5, and a first connecting channel is formed within the condenser 3, with one end of the first connecting channel communicating with the storage space; one end of the receiving component 4 is connected to the other end of the condenser 3, and a receiving space is formed within the receiving component 4, with one end of the receiving space communicating with the other end of the first connecting channel.

[0101] The steam generated by heating the distilled water in the heating element 1 is introduced into the storage space in the storage container 2. The steam comes into contact with the material to be extracted and undergoes azeotropy. The azeotropic steam is condensed by the condensing component 3 to obtain the distillate, which is finally collected by the receiving component 4.

[0102] This application adopts a design that separates the extractable material from distilled water, which not only avoids the occurrence of boiling but also prevents the heat-sensitive components (such as terpenes) in the essential oil from undergoing pyrolysis or oxidative deterioration.

[0103] The cylindrical design of the storage container 2 facilitates full contact between water vapor and the material to be extracted, avoiding the phenomenon that the material to be extracted at the edges cannot come into contact with water vapor. Since the storage cover 5 covers the feeding port 21 of the storage container 2, it is only necessary to remove the storage cover 5 to easily extract the material to be extracted into the storage space. The operation is convenient and improves the overall extraction efficiency of the device.

[0104] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0105] It should be noted that this utility model uses a novel steam distillation device for extracting plant essential oils as an example to introduce the specific structure and working principle of this utility model. However, the application of this utility model is not limited to a novel steam distillation device for extracting plant essential oils, and it can also be applied to the production and use of other similar products.

[0106] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.

[0107] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
