Description

Technical Field

[0001] This utility model relates to an extraction device, and more particularly to an extraction device for agarwood extract compound cosmetic raw materials, belonging to the field of extraction technology. Background Technology

[0002] Agarwood is a traditional and precious spice and medicinal material from China, Japan, India, Southeast Asia, and the Middle East. It primarily originates from plants in the genus *Aquilaria* of the Thymelaeaceae family, with over twenty species currently recognized as agarwood producers. *Aquilaria sinensis*, also known as native agarwood, is the only tree species in my country unique to and capable of producing agarwood. Agarwood originates from the term "sinking incense," referring to its abundant resin, which causes it to sink in water. When *Aquilaria* plants are damaged or stimulated, they produce black resin; the xylem that produces this resin is agarwood. Its formation is primarily believed to be the result of the combined action of the agarwood tree and its endophytic fungi. Agarwood is a valuable traditional Chinese medicine and natural spice, currently widely used in pharmaceuticals, incense making, and fragrance production.

[0003] Agarwood extract is a compliant and technologically mature ingredient in cosmetic formulations. Its application requires specific extraction techniques and equipment to achieve efficient retention of active ingredients, such as low-temperature solvent extraction. This process primarily utilizes temperature-controlled extraction tanks, vacuum concentrators, and spray drying towers, employing an ethanol / water mixed solvent at a low temperature of 45-60°C, combined with vacuum concentration to prevent the decomposition of some components. The temperature-controlled extraction tank plays a crucial role in the extraction of agarwood extract.

[0004] Temperature-controlled extraction tanks primarily achieve temperature control through a jacketed system. The jacket encloses the tank body, forming a sealed cavity. A heat exchange medium is continuously introduced and discharged to maintain continuous flow and indirectly transfer energy through the tank wall, achieving efficient heat exchange. However, current jacketed systems typically introduce heat at one end and exit at the other. The heat exchange medium must pass through the entire jacket cavity before exiting, making it prone to temperature gradients along the longitudinal direction. This can lead to uneven temperature distribution throughout the tank wall, and dead zones or short circuits can easily occur in the flow of the medium within the jacket, resulting in uneven local heat transfer and affecting temperature control and heat exchange efficiency. Furthermore, the rapid passage of the heat exchange medium through the jacket cavity means that its heat is not fully utilized. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an extraction device for agarwood extract compound cosmetic raw materials.

[0006] The technical solution adopted in this utility model is as follows: An extraction device for agarwood extract compounded with cosmetic raw materials is designed, comprising a tank body and a heat exchange jacket disposed outside the tank body. A stirring mechanism is disposed inside the tank body. The tank body also has an inlet, an outlet, and a driving mechanism, with the driving mechanism connected to the stirring mechanism. The heat exchange jacket includes a shell, partition rings, a medium inlet, and a medium outlet. The shell is disposed outside the tank body and forms a heat exchange cavity with the tank body. Multiple partition rings are disposed between the shell and the tank body, arranged longitudinally along the outer wall of the tank body to divide the heat exchange cavity into multiple sub-cavities. A medium inlet is disposed on the shell of each sub-cavity. The heat exchange medium simultaneously enters the corresponding sub-cavity from each medium inlet. A connecting port is disposed on the partition rings, connecting all the sub-cavities. After entering the sub-cavity, the heat exchange medium flows out through the connecting port. A medium outlet is disposed at the bottom of the heat exchange cavity, and the heat exchange medium is finally discharged through the medium outlet. The heat exchange chamber between the jacket and the tank body is divided into multiple smaller sub-cavities. Heat exchange media are then simultaneously introduced into each sub-cavity, ensuring a relatively uniform temperature across all sub-cavities. This reduces temperature differences along the longitudinal direction of the tank body, while maintaining a higher temperature within each sub-cavity, thus improving heat exchange efficiency between the sub-cavity and the material inside the tank. Furthermore, the smaller size of each sub-cavity reduces dead zones in the media flow.

[0007] Furthermore, all media inlets are located on the same side of the casing, and the connecting port is located on the side of the partition ring away from the media inlets. This allows the heat exchange medium to flow circumferentially along the tank wall after entering the sub-cavity, passing through the entire tank wall containing the sub-cavity, and then flowing out through the connecting port. This ensures that materials throughout the tank can undergo efficient heat exchange. The media outlet is located at the bottom of the heat exchange cavity on the same side as the media inlets. After the heat exchange medium flows into the bottom of the heat exchange cavity through the connecting port, it flows through most of the bottom area of ​​the heat exchange cavity before flowing out through the media inlet. This ensures that the tank wall at the bottom of the heat exchange cavity undergoes sufficient and efficient heat exchange.

[0008] Furthermore, it also includes a waste heat utilization coil, which is installed inside the tank. One end of the coil is connected to the medium outlet at the bottom of the heat exchange chamber, and the other end is connected to the outside. The heat exchange medium after heat exchange in the sub-chamber is discharged through the waste heat utilization coil. During the discharge process, it exchanges heat with the material in the tank again through the waste heat utilization coil, making full use of the heat of the heat exchange medium.

[0009] Furthermore, an inlet medium connector and an outlet medium connector are respectively provided on opposite sides of the bottom of the tank. The inlet medium connector is connected to the bottom of the heat exchange chamber, and at this time the inlet medium connector is the medium outlet of the heat exchange chamber. The outlet medium connector is connected to the outside. The two ends of the coil are connected to the inlet medium connector and the outlet medium connector respectively, making the connection simple and convenient.

[0010] Furthermore, the waste heat utilization coil includes a baffle section and a connecting section. The baffle sections are respectively arranged on opposite sides of the stirring mechanism. On the one hand, the baffle section increases the heat exchange area, and on the other hand, when the stirring mechanism stirs the material, it changes the material flow direction, increases the degree of turbulence, reduces the dead flow angle, optimizes the fluid dynamics behavior, and enhances the heat transfer / mixing efficiency. The two baffle sections are connected by the connecting section. One side of the baffle section is connected to the inlet medium connector, and the other side of the baffle section is connected to the outlet medium connector.

[0011] Furthermore, the baffle extends upward to at least two-thirds of the height of the tank's internal cavity to ensure a high baffle effect.

[0012] Furthermore, the baffle is an inverted U-shaped tube, which improves the structural strength and heat exchange area. The connecting part is a straight tube or an arc-shaped tube. When the connecting part is a straight tube, it passes through the lower end of the stirring mechanism. When the connecting part is an arc-shaped tube, it passes through the lower end of the stirring mechanism or goes around the side, which facilitates the disassembly and assembly of the waste heat utilization coil.

[0013] Furthermore, it also includes a heat exchange manifold, one end of which is closed, and along the axial direction of the manifold, there are connectors that correspond one-to-one with the medium inlet. The connectors are connected to the medium inlet, and the heat exchange medium is introduced from one end of the heat exchange manifold and then flows into the sub-cavity through each connector, which facilitates the introduction of the heat exchange medium.

[0014] Furthermore, an auxiliary outlet is provided at the bottom of the heat exchange cavity. The auxiliary outlet is located at the lowest point of the heat exchange cavity. When cleaning the heat exchange medium, the auxiliary outlet helps to quickly clean the heat exchange medium in the heat exchange cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a partition ring to divide the heat exchange cavity between the jacket and the tank body into multiple smaller sub-cavities. Then, a heat exchange medium is simultaneously introduced into each sub-cavity via a medium inlet, ensuring a relatively uniform temperature across all sub-cavities. This reduces temperature differences along the longitudinal direction of the tank body, while maintaining a higher temperature within each sub-cavity, thus improving heat exchange efficiency between the sub-cavity and the material inside the tank. Furthermore, the smaller size of each sub-cavity reduces dead zones in the medium flow.

[0016] This invention utilizes a waste heat recovery coil to discharge the heat exchange medium after heat exchange within the sub-cavity. During the discharge process, the medium exchanges heat with the material inside the tank again through the waste heat recovery coil, thus fully utilizing the heat of the heat exchange medium.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1 like Figure 1-3As shown, an extraction device for agarwood extract compounded with cosmetic raw materials includes a tank 1 and a heat exchange jacket disposed outside the tank 1. A stirring mechanism 2 (generally including a stirring shaft and stirring blades) is installed inside the tank 1. The tank 1 also has an inlet, an outlet 3, and a drive mechanism 4 (generally including a motor and coupling, etc.). The drive mechanism 4 is connected to the stirring mechanism 2, and the stirring mechanism 2 rotates under the drive of the drive mechanism 4 to stir the material inside the tank 1. It is understood that this extraction device will also be equipped with temperature sensors and valves for various pipeline passages, etc., all of which are existing technologies and will not be described in detail here. The innovation of this embodiment compared with the prior art is as follows: The heat exchange jacket includes a shell 5 (usually made of heat insulation material), a partition ring 6, a medium inlet 7, and a medium outlet. The shell 5 is disposed outside the tank body 1 and forms a heat exchange cavity with the tank body 1. The heat exchange cavity usually covers most of the side wall and bottom area of ​​the tank body 1. Multiple partition rings 6 are disposed between the shell 5 and the tank body 1. The partition rings 6 are arranged in a longitudinal array along the outer wall of the tank body 1 to divide the heat exchange cavity (especially the annular part of the heat exchange cavity) into multiple sub-cavities 8. A medium inlet 7 is disposed on the shell 5 at each sub-cavity 8 (the sub-cavity 8 at the bottom is different from the other sub-cavities 8 and does not have a medium inlet 7). A connecting port 9 is disposed on the partition ring 6. All sub-cavities 8 are connected through the connecting port 9 (the heat exchange medium in each sub-cavity 8 with a medium inlet 7 flows into the bottom sub-cavity 8 through the connecting port 9 and is then discharged from the medium outlet). A medium outlet is disposed at the bottom of the heat exchange cavity.

[0025] The partition ring 6 can be made of a thermally conductive material (existing technology), enabling efficient heat exchange on the tank wall 1 at the partition ring 6. More specifically, all medium inlets 7 are located on the same side of the casing 5, and the connecting port 9 is located on the side of the partition ring 6 away from the medium inlets 7. The connecting port 9 can be a small round hole or notch on the partition ring 6. The medium outlet is located at the bottom of the heat exchange cavity on the same side as the medium inlets 7.

[0026] Example 2 This embodiment is a further optimization of the heat exchange structure based on Embodiment 1. In this embodiment, the heat exchange jacket also includes a waste heat utilization coil 10, which is disposed inside the tank body 1, with one end connected to the medium outlet at the bottom of the heat exchange cavity and the other end connected to the outside. More specifically, an inlet medium connector 11 and an outlet medium connector 12 are respectively provided on opposite sides of the bottom of the tank body 1. The inlet medium connector 11 is connected to the bottom of the heat exchange cavity (at this time, the inlet medium connector 11 is the outlet medium port at the bottom of the heat exchange cavity), and the outlet medium connector 12 is connected to the outside. Both ends of the coil are connected to the inlet medium connector 11 and the outlet medium connector 12 respectively, and the connection is detachable (welding is also possible, but it is inconvenient for maintenance and cleaning, etc.), which facilitates disassembly and maintenance. Specifically, the connection method can be to set connecting flanges at both ends of the waste heat utilization coil 10, the inlet medium connector 11, and the outlet medium connector 12, and then fix them with bolts. A sealing ring can be set between the flanges. Flared connection or compression fitting connection can also be used, both of which are existing technologies.

[0027] Example 3 This embodiment is a further optimization of the waste heat recovery coil 10 based on Embodiment 2. The waste heat recovery coil 10 includes an integrally formed baffle section 13 and a connecting section 14. The baffle sections 13 are respectively arranged on opposite sides of the stirring mechanism 2, and are arranged longitudinally parallel to the stirring mechanism 2. The two baffle sections 13 are connected through the connecting section 14. One side of the baffle section 13 is connected to the inlet medium connector 11, and the other side of the baffle section 13 is connected to the outlet medium connector 12. The baffle section 13 extends upward to at least two-thirds of the height of the inner cavity of the tank body 1.

[0028] More specifically, the baffle 13 is an inverted U-shaped tube (or an upright M-shaped tube), and the connecting part 14 is a straight tube or an arc-shaped tube. When the connecting part 14 is a straight tube, it passes through the lower end of the stirring mechanism 2. When the connecting part 14 is an arc-shaped tube (not shown in the figure), it passes through the lower end of the stirring mechanism 2 or goes around the side, which makes it easier to disassemble and assemble.

[0029] Example 4 This embodiment is a further optimization of the extraction equipment based on Embodiment 3. The agarwood extract compound cosmetic raw material extraction equipment described in this embodiment also includes a heat exchange main pipe 15. One end of the heat exchange main pipe 15 is closed, and the other end is connected to a heat exchange medium inlet pipe (not shown in the attached drawings). Connectors 16, corresponding one-to-one with the numerous medium inlets 7 on the jacket, are arranged along the axial direction of the heat exchange main pipe 15. The connectors 16 are connected to the medium inlets 7 (they can be directly welded and fixed). An auxiliary outlet 17 is also provided at the bottom of the heat exchange chamber. The auxiliary outlet 17 is located at the lowest point of the heat exchange chamber and assists in the discharge of the heat exchange medium when no material heat exchange is being performed, resulting in faster and more thorough discharge of the heat exchange medium.

[0030] It should be noted that switches or valves (not shown in the attached diagram) are generally installed on the discharge port 3, the medium outlet connector 12, and the auxiliary discharge port 17.

[0031] Working principle: When extracting agarwood extract into cosmetic raw materials, the auxiliary outlet 17 is closed, and high-temperature steam or other heat exchange medium is introduced through the heat exchange main pipe 15. The heat exchange medium is introduced into each sub-cavity 8 through each medium inlet 7, and then flows into the bottom of the heat exchange cavity through the connecting port 9. After flowing into the waste heat utilization coil 10, it flows out through the outlet medium connector 12. Throughout the process, it continuously exchanges heat with the material being stirred in the tank 1.

[0032] It should be noted that although this application is an innovative improvement made by the inventor in the extraction of agarwood extract into cosmetic raw materials, and is mainly used for the extraction of agarwood extract into cosmetic raw materials, this application can also be used for other materials that need to be extracted using conventional extraction tanks, and there are no restrictions on this application.

[0033] Furthermore, in the description of this utility model, unless otherwise stated, the terms "multiple", "multiple roots", and "multiple groups" mean two or more, and the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
