Description

Technical Field

[0001] This utility model relates to the field of essential oil preparation technology, specifically to a distillation structure for camphor tree essential oil. Background Technology

[0002] The essential oil of the camphor tree is rich in eucalyptol, camphor, and other components, and has antibacterial and insect-repellent properties. Its essential oil is mainly extracted using steam distillation.

[0003] Existing distillation equipment often places materials in a mesh tube within a distillation tank during distillation. However, due to the limited obstruction between the mesh tube and the inner wall of the distillation tank, water vapor tends to flow upwards along the space between the inner wall of the rectifier tube and the mesh tube, resulting in poor distillation efficiency of Artemisia argyi inside the mesh tube and low practicality. To address the problems in the existing technology, a device for extracting Artemisia argyi essential oil (hereinafter referred to as Prior Art 1) with publication number CN222809428U is provided. This device includes a main tank, inside which a distillation mechanism is fixedly installed. The distillation mechanism includes an inner tank, which is fixedly located on the top of the inner side of the main tank. The inner tank has four internal cavities, and four fixed covers are fixedly installed at the bottom of the inner tank. A top cover is fixedly installed on the top of the main tank by bolts. A cooling tank is provided on one side of the main tank, and a separation box is provided at the bottom of the inner side of the cooling tank. A spiral pipe is fixedly installed inside the inner wall of the main tank.

[0004] In the prior art 1, by setting an inner cavity inside the inner tank, the material is placed in layers inside the inner cavity through the shelves, which improves the processing efficiency of the material by steam. However, in the prior art 1, the steam outlet is set at the bottom of the inner tank, and the steam diffusion path is single, which can easily lead to some raw materials on the shelves not being fully penetrated by steam, affecting the distillation effect and distillation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a distillation structure for camphor tree essential oil, which can solve the problem in the existing technology where the steam diffusion path is single, which easily leads to some raw materials on the plate not being fully penetrated by steam, thus affecting the distillation effect and efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A distillation structure for camphor tree essential oil includes a distillation tank and a steam system. Several placement plates are installed inside the distillation tank from top to bottom, and the placement plates are provided with air holes.

[0008] The steam system includes an annular steam pipe and a gas supply hood installed at the bottom of the distillation tank. The gas supply hood is provided with a first gas supply hole. The annular steam pipe is arranged correspondingly to the placement plate, and the annular steam pipe is provided with a second gas supply hole. The input ends of the annular steam pipe and the gas supply hood are both used to connect to a steam generator.

[0009] The distillation vessel is connected to a condenser assembly, which is used to condense and separate the mixed vapors.

[0010] Preferably, the condensation assembly includes a condenser tank, a condenser pipe, and a connecting pipe. The condenser pipe is installed inside the condenser tank and connected to the distillation tank via the connecting pipe. The end of the condenser pipe away from the connecting pipe is used to connect to a separator. The condenser tank is connected to an inlet pipe for inputting the condensing medium.

[0011] Preferably, the condenser is a spiral tube.

[0012] Preferably, the distillation tank is provided with a heat preservation cavity, and the condenser is connected to a liquid delivery pipe, which is connected to the heat preservation cavity through the liquid delivery pipe.

[0013] Preferably, the placement plate is conical.

[0014] Preferably, the placement plate is provided with a plurality of material-blocking protrusions.

[0015] Preferably, the placement plate is provided with a liquid collection tank.

[0016] Preferably, the material-blocking protrusions are spaced apart.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, by setting several placement plates, the material to be distilled can be placed in layers to avoid excessive accumulation of material affecting the distillation effect;

[0019] The steam generator, through the gas supply hood and the first gas supply hole, inputs steam into the distillation tank, which flows from bottom to top to distill the materials on the placement plates sequentially. The gas input into the distillation tank through the annular steam pipe and the second gas supply hole can distill the materials located at the edge of the placement plates. This allows the steam input through the first and second gas supply holes to permeate evenly upwards from the bottom of each layer of placement plates, avoiding localized steam concentration and a single steam diffusion path that fails to cover all materials due to the steam only being input through the gas supply hood, resulting in some raw materials on each placement plate not being fully permeated by the steam.

[0020] Furthermore, by setting up the annular steam pipe, the upward-moving steam can be replenished, avoiding the problem of a large amount of steam only near the placement plate close to the gas conveying hood. Attached Figure Description

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figures 1-3 This embodiment discloses a distillation structure for camphor tree essential oil, including a distillation tank 101 and a steam system 104. Several placement plates 115 are installed from top to bottom inside the distillation tank 101, and air holes are provided on the placement plates 115.

[0035] The steam system 104 includes an annular steam pipe 105 and a gas supply hood 106 installed at the bottom of the distillation tank 101. The gas supply hood 106 is provided with a first gas supply hole. The annular steam pipe 105 is correspondingly arranged with the placement plate 115, and the annular steam pipe 105 is provided with a second gas supply hole. The input ends of the annular steam pipe 105 and the gas supply hood 106 are both used to connect to a steam generator.

[0036] The distillation tank 101 is connected to a condenser assembly 107, which is used to condense and separate the mixed vapor.

[0037] In this embodiment, the distillation tank 101 includes a tank body 102 and a tank cover 103, which are detachably connected by snap-fit. A plurality of limiting blocks are provided inside the tank body 102, and these limiting blocks are sequentially connected to the tank body 102 from top to bottom. The placement plates 115 can be installed by placing them sequentially onto the limiting blocks from bottom to top. After each layer of placement plates 115 is installed, the material to be distilled can be placed on the surface of the placement plate 115. By setting a plurality of placement plates 115... 5. The materials to be distilled can be placed in layers to avoid excessive accumulation of materials affecting the distillation effect; the gas supply hood 106 is located below the bottommost placement plate 115, and annular steam pipes 105 are correspondingly arranged below the other placement plates 115 except the bottommost placement plate 115; there are several first gas supply holes, and the second gas supply holes are evenly spaced along the circumference of the annular steam pipes 105; the steam generator inputs steam into the distillation tank 101 through the gas supply hood 106 and the first gas supply holes from the bottom. The material on the placement plate 115 is distilled as it flows upward through the air holes. The gas input into the distillation tank 101 through the annular steam pipe 105 and the second air outlet can distill the material located at the edge of the placement plate 115, so that the steam input into the first air outlet and the second air outlet can permeate upward evenly from the bottom of each layer of placement plate 115, avoiding the problem of local steam concentration and single steam diffusion path caused by only inputting steam through the air outlet 106, which cannot cover all the material and cause some raw materials on each placement plate 115 to not be fully permeated by steam. Moreover, by setting the annular steam pipe 105, the upward moving steam can be supplemented, avoiding the problem of large amount of steam only near the placement plate 115 close to the air outlet 106. The mixed steam generated after the material is distilled enters the condenser assembly 107 and can be cooled, liquefied and separated in the condenser assembly 107 to obtain camphor tree essential oil. The steam generator in this embodiment is a conventional gas production device in the prior art, and its structure and function will not be described in detail here.

[0038] In some embodiments, the condensation assembly 107 includes a condenser tank 108, a condenser tube 109, and a connecting tube 110. The condenser tube 109 is installed inside the condenser tank 108 and is connected to the distillation tank 101 via the connecting tube 110. One end of the condenser tube 109 away from the connecting tube 110 is used to connect to a separator. The condenser tank 108 is connected to an inlet tube 111 for inputting condensing medium. In this embodiment, the condenser 108 is connected to the tank cover 103 via the connecting pipe 110. The end of the liquid inlet pipe 111 away from the condenser 108 is connected to a liquid source device. The liquid source device is used to input the condensing medium into the area formed between the condenser 108 and the condenser pipe 109. The liquid source device is a conventional device in the prior art, and its structure and function will not be described in detail here. After the mixed steam enters the condenser pipe 109 through the connecting pipe 110, the condensing medium in the condenser 108 can liquefy the mixed steam, causing the mixed steam to liquefy into a mixed liquid. After the mixed liquid enters the separator through the liquid outlet of the condenser pipe 109, due to the different densities of camphor tree oil and water, the mixed liquid can naturally separate into layers in the separator, making it easy to collect. In this embodiment, the separator is a conventional separation funnel in the prior art, and its structure and function will not be described in detail here.

[0039] In some embodiments, the condenser tube 109 is a spiral tube. By making the condenser tube 109 a spiral structure, the movement path and movement time of the mixed vapor entering the condenser tube 109 can be increased, thereby increasing the contact time between the mixed vapor and the condensing medium and further improving the condensation effect.

[0040] In some embodiments, the distillation tank 101 is provided with a heat-insulating cavity 112, and the condenser 108 is connected to a liquid delivery pipe 113, which connects the condenser 108 to the heat-insulating cavity 112. In this embodiment, the condensing medium, which is water after heat exchange and heating with the mixed steam in the condenser pipe 109, can enter the heat-insulating cavity 112 through the liquid delivery pipe 113 to insulate the distillation tank 101 and reduce heat loss during the distillation of the material on the placement plate 115. In this embodiment, a return pipe is connected between the heat-insulating cavity 112 and the liquid source device, and a return pump is installed on the return pipe to pump the cooled liquid in the heat-insulating cavity 112 back to the liquid source device. By setting the liquid delivery pipe 113 and the return pipe, the heat utilization efficiency can be improved while the condensing medium can be recycled.

[0041] In some embodiments, the placement plate 115 is conical. In this embodiment, the placement plate 115 has an upwardly convex conical plate structure. After the steam input into the distillation tank 101 comes into contact with the placement plate 115, the steam can diffuse from the center to the surrounding area under the guidance of the arc surface at the bottom of the placement plate 115, extending the movement path of the steam. This allows the steam to fully contact every part of the material on the placement plate 115 under the guidance of the placement plate 115, reducing the risk that the material at the edge or center of the plate may not be fully penetrated by the steam due to steam short-circuiting during existing planar plate distillation.

[0042] In some embodiments, the placement plate 115 is provided with a plurality of material-blocking protrusions 114. By providing the material-blocking protrusions 114, the friction between the placement plate 115 and the material can be increased, and the material-blocking protrusions 114 can form a plurality of partitions for limiting the material, preventing the material from gathering towards the edge of the placement plate 115 under the action of gravity, thus preventing material accumulation.

[0043] In some embodiments, the material-blocking protrusions 114 are spaced apart. By setting the spaced material-blocking protrusions 114, the material placed on the placement plate 115 can be evenly distributed within the partitions formed between the material-blocking protrusions 114, avoiding local accumulation; and the intervals between the material-blocking protrusions 114 provide a flow path for steam and condensate, ensuring that steam can penetrate the material layer to improve the overall coverage, and that the condensate formed on the surface of the placement plate 115 can also move to the collection tank under the guidance of the arc surface at the top of the placement plate 115 for collection.

[0044] In some embodiments, the steam generator can alternately input high and low pressure steam into the distillation tank 101 through the first and second air inlets. When high pressure steam is input into the distillation tank 101, the high pressure steam can impact the material layer on the placement plate 115, breaking up any clumps of material or densely packed areas, so that the steam can fully cover the material on the placement plate 115 during its movement, thereby improving distillation efficiency and distillation effect. When low pressure steam is input, the steam can slowly penetrate through the pores that have been broken up by high pressure, fully releasing the essential oil components of the material. In this embodiment, the steam generator is an existing device equipped with a control system and a pulse generator to realize steam pulse input, and its structure and function will not be described in detail here.

[0045] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
