Description

Technical Field

[0001] This utility model relates to the field of essential oil extraction technology, specifically a condensation device for extracting jasmine essential oil. Background Technology

[0002] Plant essential oil extraction is an ancient and important industrial technology. With increasing health awareness and a growing preference for natural products, the demand for essential oils is rising daily. Traditional essential oil extraction methods mainly include distillation, solvent extraction, and pressing. Among these, steam distillation is widely used in actual production due to its low cost, ease of operation, and wide applicability. However, in the traditional steam distillation process, the low condensation efficiency causes a large amount of aromatic substances to escape into the air with the steam, reducing the yield and quality of the essential oil.

[0003] Chinese patent CN206853172U discloses a condensation device for extracting jasmine essential oil. This utility model features an insulated tank with an inlet pipe at the bottom and an outlet pipe at the top. A first convex diversion funnel is located above the inlet pipe, with a first condenser above it. A second convex diversion funnel is located above the first condenser, and a second condenser is located above the second diversion funnel. The condensation temperature of the second condenser is lower than that of the first condenser. Return boxes are located at the connection points between the bottom of the first and second diversion funnels and the insulated tank, respectively. These return boxes are connected to the outside of the insulated tank via return pipes. By employing a two-stage condensation process with different temperatures at each stage, the proportion of effective components in the waste liquid is significantly reduced, improving the condensation efficiency of jasmine essential oil.

[0004] By comparing the above-mentioned utility models, it can be seen that although the utility model can improve the condensation efficiency and condensation effect to a certain extent by setting two-stage condensation, it still has the problems of limited condensation area and insufficient heat exchange. Moreover, the condenser plate is usually made of a single material, and the optimal condensation conditions for different types of essential oils are not adequately considered, which leads to the inability to fully exert the performance advantages in practical applications. Therefore, this utility model is proposed to solve the above problems. Utility Model Content

In this way, when the transmission flange is driven by an external motor, it can drive the condensing component below to rotate, thereby improving the condensing efficiency.

[0012] Furthermore, the top of the fixing frame is nested on the outside of the rotating cylinder and engages with the rotating cylinder through toothed grooves. The interior of the intermediate cylinder is provided with a partition that divides the interior of the intermediate cylinder into an air inlet chamber and an air outlet chamber.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the toothed meshing of the rotating cylinder and the fixed frame allows the rotating cylinder and the fixed frame to rotate synchronously inside the cover plate.

[0014] Furthermore, the outer side of the fixing frame is provided with several fixing holes, and the bottom of the recovery cylinder is provided with several connecting pipes. The outer horizontal pipe of the recovery cylinder passes through the fixing holes of the fixing frame, and one end of the connecting pipe is connected to the air outlet chamber of the transfer cylinder.

[0015] The beneficial effects of adopting the above-mentioned further solution are: fixing perforations are set on the outside of the fixing frame to limit the horizontal tube of the recovery cylinder, and the recovery cylinder is connected to the transfer cylinder through the connecting pipe, fixing the recovery cylinder and the transfer cylinder to form a pipeline connection structure.

[0016] Furthermore, the outer ring condenser tubes are evenly distributed at the bottom of the gas outlet chamber and both ends are connected to the interior of the gas outlet chamber and the storage cylinder, respectively. The outer ring condensate tube is wrapped around the outside of the outer ring condenser tube and is filled with condensate inside.

[0017] The beneficial effects of adopting the above-mentioned further solution are: by setting an outer ring condensate pipe to wrap around the outer ring condenser tube and injecting condensate to condense and cool down, the purpose of condensation is achieved. At the same time, different condensates can be replaced according to actual needs to improve the condensation efficiency.

[0018] Furthermore, the inner ring condenser tubes are evenly arranged at the bottom of the air inlet chamber and their two ends are respectively connected to the interior of the air inlet chamber and the storage cylinder. The inner ring condensate tube is wrapped around the outside of the inner ring condenser tube and is filled with condensate inside.

[0019] The beneficial effects of adopting the above-mentioned further solution are: by setting an inner ring condensate pipe to wrap the outer side of the inner ring condenser and injecting condensate to achieve condensation and cooling, the purpose of condensation is achieved. At the same time, different condensates can be replaced according to actual needs to improve the condensation efficiency.

[0020] Furthermore, the top of the exhaust hood is embedded inside the transfer cylinder and rotatably connected to the transfer cylinder.

[0024] Compared with the prior art, this utility model provides a condensation device for jasmine essential oil extraction, which has the following beneficial effects:

[0025] 1. This condensation device for jasmine essential oil extraction connects the air inlet hopper and the essential oil steam pipe. Steam enters the interior of the air inlet pipe through the air inlet hopper and then enters the interior of the air inlet chamber through the exhaust port of the exhaust hood. The steam inside the air inlet chamber passes through the connection hole between the inner ring condenser and the air inlet chamber and enters the interior of the inner ring condenser. The condensate inside the inner ring condenser absorbs a certain amount of heat from the steam in the inner ring condenser, and part of the processed extract is accumulated inside the storage cylinder, thus achieving preliminary condensation extraction.

[0026] 2. This condensation device for jasmine essential oil extraction continuously feeds the storage tank. Some of the steam enters the outer ring condenser through the connection hole between the storage tank and the outer ring condenser. After the condensate inside the outer ring condenser absorbs a certain amount of heat from the steam, the steam enters the outlet chamber. The condensed extract accumulates inside the outlet chamber and flows back to the storage tank along the outer ring condensate. The steam completes condensation after passing through the inner and outer ring condensate tubes, and accumulates inside the storage tank. This solves the problems of limited condenser plate area and insufficient consideration of optimal condensation conditions for different types of essential oils in traditional condensers.

[0032] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-4 A condensation device for extracting jasmine essential oil in this embodiment includes an outer cylinder 1, a cover plate 2 threaded to the top of the outer cylinder 1, a bottom plate 3 threaded to the bottom of the outer cylinder 1, and a rotating cylinder 4 rotatably connected inside the cover plate 2. A condensation component 5 is provided on the outer side of the bottom of the rotating cylinder 4, and a feeding component 6 is provided inside the bottom plate 3.

[0034] In this example, the rotating cylinder 4 is provided with a rotating transmission flange 41. The rotating connection between the transmission flange 41 and the rotating cylinder 4 is configured so that the discharge pipe 59 can vertically penetrate the transmission flange 41 and be fixedly installed with the inner side wall of the transmission flange 41 by a snap fastener. The snap fastener installation facilitates disassembly and cleaning in the future. At the same time, the transmission flange 41 cooperates with the external drive motor to drive the discharge pipe 59 and other components to rotate, thereby causing the internal condensation structure to rotate and improving the condensation efficiency.

[0035] In this example, the condensation assembly 5 includes a fixed frame 51 disposed on the outside of the rotating cylinder 4, a transfer cylinder 52 fixedly installed at the bottom of the fixed frame 51, a plurality of outer ring condenser pipes 53 disposed at the bottom of the transfer cylinder 52, an outer ring condensate pipe 54 disposed on the outside of the outer ring condenser pipes 53, an inner ring condenser pipe 55 disposed at the bottom of the transfer cylinder 52, an inner ring condensate pipe 56 disposed on the outside of the inner ring condenser pipes 55, a storage cylinder 57 fixedly installed at the bottom of the inner ring condensate pipe 56, a recovery cylinder 58 disposed at the top of the transfer cylinder 52, and a discharge pipe 59 fixedly installed at the top of the recovery cylinder 58.

[0036] The top of the fixed frame 51 is nested on the outside of the rotating cylinder 4 and engages with the rotating cylinder 4 through toothed meshing. The toothed meshing between the fixed frame 51 and the rotating cylinder 4 allows the fixed frame 51 to rotate synchronously with the rotating cylinder 4, while also facilitating the disassembly of the fixed frame 51 and the rotating cylinder 4. The interior of the transfer cylinder 52 is provided with a partition that divides the interior of the transfer cylinder 52 into an air inlet chamber 511 and an air outlet chamber 512. The partition separates the interior of the transfer cylinder 52, allowing steam to enter the transfer cylinder 52, circulate, and move and transfer along a designated path.

[0037] The outer side of the fixing frame 51 is provided with several fixing holes, and the bottom of the recovery cylinder 58 is provided with several connecting pipes 510. The outer horizontal pipe of the recovery cylinder 58 passes through the fixing holes of the fixing frame 51. The fixing frame 51 limits the recovery cylinder 58. At the same time, one end of the connecting pipe 510 at the bottom of the recovery cylinder 58 is connected to the air outlet chamber 512 of the transfer cylinder 52, so that the recovery cylinder 58 and the transfer cylinder 52 are synchronously connected and fixed.

[0038] The outer ring condenser tubes 53 are evenly distributed at the bottom of the gas outlet chamber 512 and are connected to the interior of the gas outlet chamber 512 and the storage cylinder 57 at both ends. After passing through the gas outlet chamber 512, the steam enters the interior of the storage cylinder 57 along the outer ring condenser tubes 53. In addition, the outer ring condensate tube 54 is wrapped around the outside of the outer ring condenser tubes 53 and is filled with condensate. This allows the steam passing through the outer ring condenser tubes 53 to absorb heat from the condensate inside the outer ring condenser tubes 53, thereby reducing its temperature and achieving the condensation effect.

[0039] The inner ring condenser tube 55 is evenly arranged at the bottom of the air inlet chamber 511 and its two ends are connected to the interior of the air inlet chamber 511 and the storage cylinder 57, respectively. This allows steam to enter the interior of the inner ring condenser tube 55 along the air inlet chamber 511. In addition, the inner ring condensate tube 56 is wrapped around the outside of the inner ring condenser tube 55 and is filled with condensate. This condensation effect is achieved by condensing the steam passing through the inner ring condenser tube 55.

[0040] It should be noted that the inner ring condensate pipe 56 and the outer ring condensate pipe 54 are provided with condensate inlets and outlets on the bottom outer side, and different types of condensate can be replaced according to actual condensation needs.

[0041] In this example, the feeding assembly 6 includes an air inlet hopper 61 disposed inside the base plate 3, an air inlet pipe 62 fixedly installed on the top of the air inlet hopper 61, and an exhaust hood 63 fixedly installed on the top of the air inlet pipe 62.

[0042] The exhaust hood 63 is embedded in the interior of the transfer cylinder 52 and is rotatably connected to the transfer cylinder 52. The rotatable connection between the exhaust hood 63 and the transfer cylinder 52 allows the transfer cylinder 52 to rotate without affecting the exhaust hood 63. At the same time, a sealing device is provided between the exhaust hood 63 and the transfer cylinder 52 to seal the connection between the two, so that steam can only move along a designated trajectory to prevent it from escaping. In addition, the surface of the exhaust hood 63 is provided with several air outlets 64, and the side of the air inlet chamber 511 is provided with a slot for use with the exhaust hood 63. In this way, the steam released in the exhaust hood 63 can smoothly enter the air inlet chamber 511 for condensation.

[0043] The bottom of the base plate 3 has an opening, and the air intake hopper 61 is embedded in the opening and rotatably connected to the base plate 3. The rotatable connection between the air intake hopper 61 and the base plate 3 allows the air intake hopper 61 to rotate in time when the exhaust hood 63 appears, and it can also rotate to a certain extent. The storage cylinder 57 has a through slot for use with the air intake hopper 61. The through slot inside the storage cylinder 57 wraps around the outside of the air intake hopper 61, so that the air intake pipe 62 can pass smoothly through the storage cylinder 57 and extend to the top inside the device.

[0044] It should be noted that condensation facilities such as condensate are existing technologies, and their specific structures and working principles will not be elaborated upon in this article.

[0045] The working principle of the above embodiments is as follows:

[0046] After connecting the air inlet 61 and the essential oil steam pipe, the steam enters the interior of the air inlet pipe 62 through the air inlet 61. The steam passes through the air outlet 64 of the exhaust hood 63 and enters the interior of the air inlet chamber 511. The steam inside the air inlet chamber 511 passes through the connection hole between the inner ring condenser pipe 55 and the air inlet chamber 511 and enters the interior of the inner ring condenser pipe 55. The condensate inside the inner ring condenser pipe 56 absorbs the heat of the steam in the inner ring condenser pipe 55 to a certain extent. After a portion of the processed extract is collected inside the storage cylinder 57, preliminary condensation extraction is achieved.

[0047] Furthermore, by continuously feeding the storage cylinder 57, some steam enters the outer ring condenser 53 through the connection hole between the storage cylinder 57 and the outer ring condenser 53. After the steam heat from the outer ring condenser 53 is absorbed to a certain extent by the condensate inside the outer ring condenser pipe 54, the steam enters the outlet chamber 512. The condensed extract accumulates inside the outlet chamber 512, while simultaneously flowing back to the storage cylinder 57 along the outer ring condenser pipe 54. After undergoing dual condensation by the inner ring condenser pipe 55 and the outer ring condenser pipe 54, the steam completes condensation and accumulates inside the storage cylinder 57. This solves the problems of limited condenser plate area and insufficient consideration of optimal condensation conditions for different types of essential oils in traditional condensers. All electrical components mentioned in this text are electrically connected to the main controller and power supply. The main controller can be a conventionally known device such as a computer, and existing publicly available electrical connection technologies are not described in detail here.
