A plant-based natural spice extract evaporation device

Abstract

The present invention belongs to the technical field of fragrance preparation, and specifically discloses a plant-based natural fragrance extract evaporation device. A lifting plate is fixedly connected to a transmission part, so that the transmission part can drive the lifting plate to move. The heat-receiving end of the heat-conducting part is arranged near one side of the heating element, and the heat-dissipating end is a columnar structure and is inserted into a through hole. When the lifting plate moves, the extract above the lifting plate slowly enters the bottom of the lifting plate through the gap between the heat-dissipating end and the through hole, and forms a liquid film on the outer side of the heat-dissipating end, thereby achieving uniform heating of the liquid film. When the lifting plate moves before, the attached liquid film will contact and merge into the extract as the lifting plate moves. As the lifting plate moves again, a new liquid film will be formed, achieving uniform heating of the extract inside the tank body, avoiding the uneven heating of the extract in the existing solution, and improving the practicality of the device.

Description

Technical Field

[0001] The invention relates to the technical field of spice preparation, and in particular to an evaporation device for plant-derived natural spice extract. Background Art

[0002] Plant-based natural fragrances are organic mixtures extracted from the flowers, grasses, leaves, stems, fruits, roots, bark and other tissues of aromatic plants. They are usually used to make products such as essential oils. In the process of extracting plant-based natural fragrances, the flowers, leaves and other tissues of aromatic plants are generally extracted to obtain plant-based natural fragrance extracts. The extracts are then separated into water and oil through distillation and other methods to obtain the essential oils of plant-based natural fragrances. In the process of evaporating the plant-based natural fragrance extracts, in order to prevent the oil in the extracts from decomposing at high temperatures, a plant-based natural fragrance extract evaporation device is required.

[0003] An evaporator is a device that evaporates the extract. Traditional evaporators are broadly classified into two categories: circulating and film evaporators. Circulating evaporators are further divided into natural circulation and forced circulation. All evaporators consist of a heating chamber and an evaporation chamber, with the evaporation chamber primarily serving as a vapor-liquid separation chamber. Both circulating and film evaporators operate on the principle that liquid flows through a heating tube bundle and is then heated by steam outside the bundle, vaporizing the liquid. In other words, a heat-conducting medium is used to heat the plant-based natural spice extract, achieving evaporation.

[0004] However, during the evaporation process, the temperature of the extract is controlled by controlling the temperature of the heat-conducting medium. During this process, it is difficult to control the temperature of each area in the extract to be uniform, that is, the heating is uneven. Lower temperatures will lead to lower evaporation efficiency, and higher temperatures will cause the oil in some plant-based natural flavor extracts to decompose, resulting in insufficient practicality of the evaporation device.

[0064] Example 1

[0065] This embodiment provides a plant-based natural flavor extract evaporation device, such as Figures 1 to 9As shown, it includes a housing component 1, a transmission component 2 and a heating component. Among them, the shell assembly 1 includes a tank body 11, and the tank body 11 is provided with a first accommodating cavity 111 for storing the extraction liquid; the transmission assembly 2 is arranged in the first accommodating cavity 111, and the transmission assembly 2 includes a transmission member 21 and a lifting plate 22. The transmission member 21 has a transmission part 211 that moves along the height direction. The lifting plate 22 is fixedly connected to the transmission part 211. The lifting plate 22 is provided with multiple through holes 221, and the axial direction of any through hole 221 is arranged parallel to the height direction; the heating assembly includes a heating member 31 and multiple heat conducting members 32. The heating member 31 is located below the tank body 11 and is used to heat the tank body 11. The heat conducting members 32 are arranged one-to-one corresponding to the through holes 221. The heat conducting members 32 are provided with a heated end 321 and a heat dissipating end 322. The heated end 321 is arranged close to one side of the heating member 31. The heat dissipating end 322 is a columnar structure. The heat dissipating end 322 is located above the heated end 321 along the height direction, and the heat dissipating end 322 is passed through the through hole 221.

[0066] The plant-based natural flavor extract evaporation device of the above structure is configured such that the lifting plate 22 is fixedly connected to the transmission part 211, so that the transmission part 21 can drive the lifting plate 22 to move; the heated end 321 of the heat-conducting member 32 is arranged close to the side of the heating element 31, and the heat dissipation end 322 is a columnar structure and is passed through the through hole 221 provided on the lifting plate 22, so that when the lifting plate 22 moves, the extract above the lifting plate 22 slowly enters the bottom of the lifting plate 22 through the gap between the heat dissipation end 322 and the through hole 221, and is discharged at the heat dissipation end 322. A liquid film is formed on the outside of the columnar structure to achieve uniform heating of the liquid film; at the same time, when the lifting plate 22 is performing the previous movement, the liquid film attached to the columnar structure will contact and merge into the extraction liquid as the lifting plate 22 moves again, and as the lifting plate 22 moves again, the extraction liquid above the lifting plate 22 will pass through the gap again and attach to the outside of the columnar structure, that is, the lifting plate 22 will regenerate the liquid film when it moves, so that the extraction liquid inside the tank body 11 is uniformly heated, avoiding the phenomenon of uneven heating of the extraction liquid in the existing scheme, and improving the practicality of the device.

[0067] It can be explained that the plant-based natural flavor extract evaporation device provided in this embodiment can make the radial dimension of the through hole 221 larger than the radial dimension of the heat dissipation end 322, so that the extract can pass through the gap between the heat dissipation end 322 and the through hole 221 and adhere to the outside of the heat dissipation end 322.

[0068] The plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9As shown, the shell assembly 1 also includes an outer shell 12, a second accommodating cavity 121 for placing the tank body 11 is provided inside the outer shell 12, and a first heat-conducting cavity 122 for accommodating a heat-conducting medium is opened on the outer shell 12; the heating element 31 is arranged between the lifting plate 22 and the bottom of the second accommodating cavity 121 along the height direction.

[0069] The plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9 As shown, the bottom of the second accommodating cavity 121 and the outer wall of the tank body 11 are filled with a heat-conducting medium; the transmission member 21 also includes a guide portion 212 and a limiting portion 213. The interior of the guide portion 212 is provided with a second heat-conducting cavity 214 for accommodating the heat-conducting medium, and the limiting portion 213 is located inside the second heat-conducting cavity 214; one end of the transmission portion 211 is movably provided in the guide portion 212 and extends into the second heat-conducting cavity 214 and is fixedly connected to the limiting portion 213. The other end of 11 is fixedly connected to the lifting plate 22; the transmission assembly 2 also includes a first pipe fitting 23, a pump body 24 and a second pipe fitting 25. A transmission channel for transmitting a heat-conducting medium is provided inside the first pipe fitting 23. One end of the transmission channel is connected to the first heat-conducting cavity 122, and the other end of the transmission channel is connected to the second heat-conducting cavity 214. The oil inlet of the pump body 24 is connected to the bottom of the second accommodating cavity 121, and the oil outlet of the pump body 24 is connected to the second heat-conducting cavity 214 through the second pipe fitting 25.

[0070] The plant-based natural fragrance extract evaporation device of this structure connects the oil inlet of the pump body 24 with the bottom of the second accommodating chamber 121, and connects the oil outlet of the pump body 24 with the second heat-conducting chamber 214. Under the action of the pump body, the heat-conducting medium between the second accommodating chamber 121 and the tank body 11 can be transferred to the second heat-conducting chamber 214, thereby increasing the cavity pressure of the second heat-conducting chamber 214. At this time, since the transmission part 211 is movably arranged in the guide part 212, and the limiting part 213 is located inside the second heat-conducting chamber 214, after the cavity pressure of the second heat-conducting chamber 214 increases, the limiting part 213 will be driven to move. At this time, since the transmission part 211 is fixedly connected to the limiting part 213, the limiting part 213 drives the transmission part 211 to move, and since the transmission part 211 is fixedly connected to the lifting plate 22, the transmission part 211 drives the lifting plate 22 to move.

[0071] The plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9As shown, the housing assembly 1 further includes a separator 13, which is used to divide the first heat-conducting cavity 122 to form a disconnected third heat-conducting cavity 123 and a fourth heat-conducting cavity 124; the first pipe fittings 23 are arranged in pairs, and the two ends of one first pipe fitting 23 are respectively connected to the third heat-conducting cavity 123 and the second heat-conducting cavity 214, and the two ends of the other first pipe fitting 23 are respectively connected to the fourth heat-conducting cavity 124 and the second heat-conducting cavity 214; the second pipe fittings 25 are three-way pipe fittings, and the second pipe fittings 25 are arranged in pairs, and one second pipe fitting 25 has a first end 251, a second end 252 and a third end 253, the first end 251 is connected to the oil outlet of the pump body 24, and the second end 252 is connected to the third heat-conducting cavity 123 and the fourth heat-conducting cavity 124. One of the two is connected, and the third end 253 is connected to the second accommodating cavity 121. The other second pipe member 25 has a fourth end 254, a fifth end 255 and a sixth end 256. The fourth end 254 is connected to the oil inlet of the pump body 24, the fifth end 255 is connected to the other of the third heat-conducting cavity 123 and the fourth heat-conducting cavity 124, and the sixth end 256 is connected to the second accommodating cavity 121; the transmission assembly 2 also includes a first switch member 26 and a second switch member 27 arranged in pairs, one first switch member 26 is installed on the second end 252, the other first switch member 26 is installed on the fifth end 255, one second switch member 27 is installed on the third end 253, and the other second switch member 27 is installed on the sixth end 256.

[0072] It can be explained that the plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9 As shown, the first switch element 26 at the second end 252 and the first switch element 26 installed at the fifth end 255 will not be in the on state or the off state at the same time, and the second switch element 27 installed at the third end 253 and the second switch element 27 installed at the sixth end will not be in the on state or the off state at the same time; at the same time, the first switch element 26 at the second end 252 and the second switch element 27 at the third end 253 will not be in the on state or the off state at the same time, and the first switch element 26 installed at the fifth end 255 and the second switch element 27 installed at the sixth end 256 will not be in the on state or the off state at the same time.

[0073] As one of the embodiments, when the first switch element 26 at the second end 252 is in the on state, the second switch element 27 installed at the sixth end 256 is in the on state, and the second switch element 27 installed at the third end 253 and the first switch element 26 installed at the fifth end 255 are both in the off state.

[0074] In the evaporation device for natural plant fragrance extract of this structure, the second switch member 27 provided at the oil inlet of the pump body 24 is opened, and the first switch member 26 installed at the oil inlet of the pump body 24 is closed. The first switch member 26 at the oil outlet of the pump body 24 is opened, and the second switch member 27 installed at the oil outlet of the pump body 24 is closed. Under the action of the pump body 24, the heat-conducting medium between the second accommodating cavity 121 and the tank body 11 passes through the pump body and enters one of the third heat-conducting cavity 123 and the fourth heat-conducting cavity 124, and then enters the second heat-conducting cavity 214 of the transmission member 21 through the first pipe member 23 connected to the cavity. Then, the cavity pressure of the second heat-conducting cavity 214 increases to push the limiting part 213 to move, so that the limiting part 213 drives the transmission part 211 to move, and finally the transmission part 211 drives the lifting plate 22 to descend; until the limiting part 213 abuts against the wall surface of the second heat-conducting cavity 214 After that, the descending process is completed. At this time, the heat-conducting medium has filled the second heat-conducting cavity 214, and the heat-conducting medium inside the first pipe 23 enters the other first pipe 23, and then enters the other cavity of the third heat-conducting cavity 123 and the fourth heat-conducting cavity 124. At this time, the second switch 27 set at the oil inlet of the pump body 24 is closed, and the first switch 26 installed at the oil inlet of the pump body 24 is opened. The first switch 26 at the oil outlet of the pump body 24 is closed, and the second switch 27 installed at the oil outlet of the pump body 24 is opened. Under the action of the pump body, the heat-conducting medium in the second heat-conducting cavity 214, the third heat-conducting cavity 123 and the fourth heat-conducting cavity 124 is extracted and transferred to the bottom of the second accommodating cavity 121, so that the cavity pressure of the second heat-conducting cavity 214 is reduced. Through the action of the limiting part 213, the transmission part 211 is lifted, and the lifting process of the lifting plate 22 is completed. Then the above-mentioned descending process and ascending process are repeated to complete the periodic descending and ascending of the lifting plate 22 .

[0075] In order to increase the airtightness of the two independent spaces formed above and below the lifting plate 22 during the process of rising and falling, a sealing member needs to be attached to the wall of the lifting plate 22 near the first accommodating cavity 111. Therefore, the plant-based natural flavor extract evaporation device provided in this embodiment, such as Figures 1 to 9 As shown, the first sealing member 29 should also be included. In this embodiment, the first sealing member 29 is located between the lifting plate 22 and the first accommodating cavity 111, and the first sealing member 29 is connected to the lifting plate 22. As one embodiment, the first sealing member 29 is selected as a sealing ring, such as an O-ring.

[0076] The plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9 As shown, the lifting plate 22 is a cylindrical structure; multiple groups of through holes 221 are provided, and the multiple groups of through holes 221 are arranged in a circumferential array along the circumferential direction of the lifting plate 22.

[0077] The plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9 As shown, any group of through holes 221 is provided with a plurality of through holes, and adjacent through holes 221 are arranged in an array with equal distances along the radial direction of the lifting plate 22 .

[0078] The plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9 As shown, the second accommodating cavity 121 has an opening at its upper side in the height direction. The housing assembly 1 also includes a top cover 14, one side of which is hingedly connected to the wall of the opening. The top cover 14 has a closed state in which, under the action of an external force, the cover is rotated at the opening to isolate the second accommodating cavity 121 from the outside world, and an open state in which the cover is rotated in the opposite direction to connect the second accommodating cavity 121 to the outside world. The transmission assembly 2 also includes a third pipe 28, one side of which is connected to the lifting plate 22, and the other side of which extends toward one side of the opening, leaving a gap between the third pipe 28 and the top cover 14. In this embodiment, the connection between the third pipe 28 and the lifting plate 22 is connected to the space below the lifting plate 22.

[0079] In the evaporation device for plant-based natural flavor extracts of this structure, a gap is provided between the third pipe 28 and the top cover 14. As the lifting plate 22 rises, the gas above the lifting plate 22 can enter the space below the lifting plate 22 through the third pipe 28. This avoids the phenomenon that the lifting plate is moved when the space above the lifting plate 22 is closed, causing the gas pressure to gradually increase, causing the pressurized extract to quickly pass through the gap and enter the space below the lifting plate.

[0080] Since many bubbles will be generated in the extraction process, these bubbles will gradually accumulate on the surface of the extract. If the bubbles are not removed in time, the evaporation efficiency of the extract will be affected, and thus the efficiency of extracting the active ingredients of the fragrance will be affected. Figures 1 to 9As shown, the plant-based natural flavor extract evaporation device provided in this embodiment further includes a spray assembly 4. The spray assembly 4 includes an annular seat 41, a plurality of heat conducting sheets 42, a fourth pipe 43 and a plurality of third switch members 44. Among them, the annular seat 41 is arranged above the first accommodating cavity 111 along the height direction, and a closed annular groove is provided inside the annular seat 41; a plurality of heat-conducting plates 42 are arranged in a circular array along the radial direction of the annular seat 41, and any heat-conducting plate 42 is provided with a first heat-conducting portion 421 and a second heat-conducting portion 422, the first heat-conducting portion 421 is located in the annular groove, one end of the second heat-conducting portion 422 is connected to the first heat-conducting portion 421, and the other end of the second heat-conducting portion 422 is inserted into the annular seat 41 and then plugged into the inner wall surface of the tank body 11; one end of the fourth pipe fitting 43 is inserted into the annular seat 41 and connected with the annular groove, and the other end of the fourth pipe fitting 43 is inserted into the tank body 11 and connected with the outlet of the external water storage component; the third switch component 44 is installed at the bottom of the annular seat 41 to control the connection or disconnection of the annular groove and the first accommodating cavity 111.

[0081] It should be noted that the plant-based natural flavor extract evaporation device provided in this embodiment does not impose any restrictions on the type of third switch element 44. In one embodiment, the third switch element 44 is a pneumatic switch. In this case, the inlet of the pneumatic switch is disposed through the annular seat 41, and the outlet of the pneumatic switch extends toward the side near the heat conductor 32.

[0082] It can be explained that, in order to facilitate the puncture of bubbles on the surface of the extract, the plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figure 6 As shown, it should also include a spray head 45. In this case, the spray head 45 is selected as a nozzle, so that the sprayed pure water diverges and punctures the bubbles on the surface of the extraction liquid over a large area, thereby improving the efficiency of removing bubbles.

[0083] It can be explained that the plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9 As shown, the second sealing member 46 is further included. The second sealing member 46 is arranged between the fourth pipe member 43 and the external water storage member. In this embodiment, the second sealing member 46 is selected as a sealing cover.

[0084] In the evaporation device for plant-based natural fragrance extract of this structure, the first heat-conducting part 421 is located in the annular groove, the second heat-conducting part 422 is inserted into the inner wall surface of the tank body 11 after passing through the annular seat 41, and the annular seat 41 is located above the first accommodating cavity 111, so the annular seat 41 is heated; the fourth pipe fitting 43 serves as a water injection pipe fitting, one end of which is connected to the annular seat 41 and the other end is connected to the external water storage member. After the pure water is transferred from the water storage member to the annular groove, that is, after the pure water is injected into the annular groove of the annular seat 41 through the fourth pipe fitting 43, a part of the pure water will evaporate after being heated, resulting in the coexistence of water vapor and liquid pure water in the annular groove. At this time, after the air pressure in the annular groove rises, the third switch member 44 is opened to allow the liquid pure water below the annular groove to flow to the extract side of the first accommodating cavity 111, puncturing the bubbles floating on the surface of the extract, thereby improving the extraction efficiency of the plant-based natural fragrance extract evaporation device.

[0085] The plant-based natural flavor extract evaporation device provided in this embodiment is as follows: Figures 1 to 9 As shown, the housing assembly 1 further includes a base 15 , which is installed below the shell 12 along the height direction.

[0086] The plant-based natural flavor extract evaporation device provided in this embodiment is used as follows:

[0087] (1) First open the top cover 14, pour the plant-based natural flavor extract into the tank body 11, and then close the top cover 14;

[0088] (2) Connect the output pipe 16 to the external condensing device, then turn on the switch of the heating element 31. When the heating element 31 is working, it heats the thermal oil below the inner portion of the housing 12;

[0089] (3) Then drive the pump body 24 to work, open the second switch 27 provided at the oil inlet of the pump body 24, close the first switch 26 installed at the oil inlet of the pump body 24, open the first switch 26 at the oil outlet of the pump body 24, and close the second switch 27 installed at the oil outlet of the pump body 24. Under the action of the pump body 24, the heat-conducting medium between the second accommodating cavity 121 and the tank body 11 passes through the pump body and enters one of the third heat-conducting cavity 123 and the fourth heat-conducting cavity 124, and then enters the second heat-conducting cavity 214 of the transmission member 21 through the first pipe member 23 connected to the cavity. Then, the cavity pressure of the second heat-conducting cavity 214 increases to push the limiting part 213 to move, so that the limiting part 213 drives the transmission part 211 to move, and finally the transmission part 211 drives the lifting plate 22 to descend;

[0090] (4) After the descent process is completed, the second switch 27 provided at the oil inlet of the pump body 24 is closed, the first switch 26 installed at the oil inlet of the pump body 24 is opened, the first switch 26 at the oil outlet of the pump body 24 is closed, and the second switch 27 installed at the oil outlet of the pump body 24 is opened. Under the action of the pump body, the heat-conducting medium in the second heat-conducting cavity 214, the third heat-conducting cavity 123 and the fourth heat-conducting cavity 124 is extracted and transferred to the bottom of the second accommodating cavity 121, so that the cavity pressure of the second heat-conducting cavity 214 is reduced. Through the action of the limiting portion 213, the transmission portion 211 is lifted up, and the lifting process of the lifting plate 22 is completed;

[0091] (5) The above-mentioned descending and ascending processes are then repeated to complete the periodic descent and ascent of the lifting plate 22 , so that the heat transfer medium circulates in the third heat transfer cavity 123 and the fourth heat transfer cavity 124 to heat the side wall of the tank body 11 .

[0092] It should be noted that in the evaporation device for the plant-based natural flavor extract provided in this embodiment, during the ascending process of the lifting plate 22, due to the gap between the third pipe 28 and the top cover 14, the gas above the lifting plate 22 can enter the space below the lifting plate 22 through the third pipe 28, so that the extract above the lifting plate 22 can slowly flow to the bottom of the lifting plate 22 through the gap between the heat-conducting member 32 and the through hole 221. During the flow, a liquid film is continuously formed on the outer side of the heat dissipation end 322, so that the heat dissipation end continuously and evenly heats the liquid film, thereby completing the uniform heating of the extract inside the tank body 11. At the same time, during the process of the liquid film merging into the extract, convection is formed between the extract and the air in the first accommodating cavity 111, heat exchange is performed, and the extract can be quickly evaporated.

[0093] It should be noted that the plant-based natural flavor extract evaporation device provided in this embodiment will generate a lot of bubbles during the evaporation process of the extract, and when the bubbles accumulate on the surface of the extract, they will affect the evaporation rate of the extract at the surface position. At this time, pure water can be injected into the annular groove of the annular seat 41 through the fourth pipe 43. After being heated, part of the pure water will evaporate, resulting in the coexistence of water vapor and liquid pure water in the annular groove. At this time, after the air pressure in the annular groove rises, the third switch 44 is opened to allow the liquid pure water below the annular groove to flow to the extract side of the first accommodating cavity 111, puncturing the bubbles floating on the surface of the extract, thereby improving the extraction efficiency of the plant-based natural flavor extract evaporation device.

[0094] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
