Description

Technical Field

[0001] The present application relates to the field of cinnamaldehyde preparation, and in particular to a cinnamaldehyde purification device and method. Background Art

[0002] Currently, most of the purification of cinnamaldehyde is carried out by steam distillation. However, during the steam distillation purification, cinnamaldehyde reacts with the gas in the steam, which ultimately leads to a very low yield of cinnamaldehyde and low efficiency in the purification of cinnamaldehyde.

[0003] However, the use of a vacuum dry pot heating purification method will result in lower purification efficiency due to uneven heating of the cinnamaldehyde raw material. Therefore, it is difficult to solve the problem of low purification efficiency of cinnamaldehyde. Summary of the Invention

[0004] In order to improve the problem of low purification efficiency of cinnamaldehyde, which is difficult to solve, the present application provides a cinnamaldehyde purification device and method.

[0005] The present application provides a cinnamaldehyde purification device and method using the following technical solutions:

[0006] A cinnamaldehyde purification device, the purification device is used to purify cinnamaldehyde using cinnamon leaves as raw materials; the purification device comprises: a reactor for forming a reaction chamber in a vacuum state; a heating element, which is arranged in the reaction chamber and forms a spiral cavity with the reaction chamber for accommodating the high-temperature state of the cinnamon leaves; a driving element, the driving element being used to drive the heating element to rotate so as to rotate the spiral cavity and drive the cinnamon leaves to move in the spiral cavity; wherein, a plurality of material transport cavities are formed on the reaction chamber; the inner wall surface of the reaction chamber coincides with the edge of the spiral cavity; the material transport cavity is recessed relative to the inner wall surface of the reaction chamber away from the spiral cavity; the material transport cavity is connected to the spiral cavity; the heating element is used to heat the reactor so that the inner wall surface of the reaction chamber and the inner wall surface of the material transport cavity are in a high-temperature state.

[0007] By adopting the above-mentioned technical scheme, the contact heating under vacuum state heats up cinnamon leaf, thereby cinnamon leaf is in the process of obtaining cinnamaldehyde by heating, cinnamon leaf will not be in contact with any air, thereby cinnamaldehyde will not be in contact with any air, thereby avoiding cinnamaldehyde and air to react and cause the purity and the problem of low efficiency of cinnamaldehyde purification.In addition, the rotation of spiral cavity is utilized to make cinnamon leaf move in spiral cavity, thereby making cinnamon leaf roll in the process of moving, making cinnamon leaf heated more evenly, ensuring the efficiency of cinnamon leaf purification.And the arrangement of material transport cavity is when cinnamon leaf moves to the top of spiral cavity, can fall downwards, then again move in spiral cavity, thereby realize that cinnamon leaf continues to move and rolls in the process of moving, better ensuring the efficiency of cinnamon leaf purification of cinnamaldehyde.

[0008] Optionally, a collecting structure is formed on the bottom surface of the reaction chamber; the collecting structure is used to collect cinnamon leaves to the middle of the reaction chamber; the spiral cavity is formed in the middle of the reaction chamber, so that the cinnamon leaves collected in the middle of the reaction chamber can move into the spiral cavity.

[0009] By adopting the above technical solution, the cinnamon leaves can be better moved into the spiral cavity again after being collected, ensuring that the cinnamon leaves can be continuously transported in the spiral cavity, improving the uniform heating of the cinnamon leaves to ensure the efficiency of purification.

[0010] Optionally, a pressure relief structure is formed on the top surface of the reaction chamber, and the pressure relief structure is used to disperse the cinnamon leaves on the upper part of the spiral cavity to the edge of the spiral cavity.

[0011] By adopting the above technical solution, it is avoided that the cinnamon leaves are squeezed after moving to the top of the spiral cavity, which makes it difficult for the cinnamon leaves to fall down in time.

[0012] Optionally, the heating element includes: a rotating shaft, a spiral plate and a heating structure; the spiral plate is fixed to the rotating shaft; an oil inlet is formed at one end of the rotating shaft, and an oil outlet is formed at the other end; a connecting cavity with a shape matching the spiral cavity is formed in the spiral plate; the connecting cavity is used to connect the oil inlet and the oil outlet; the heating structure is used to add oil in a high-temperature state into the connecting cavity through the oil inlet and discharge it through the oil outlet.

[0013] By adopting the above technical solution, high-temperature oil is introduced into the connecting cavity, and then the high-temperature oil will exchange heat with the spiral plate, thereby increasing the temperature of the spiral plate. The cinnamon leaves are in contact with the spiral plate, thereby heating the cinnamon leaves. The inner wall surface of the reaction chamber can also heat the cinnamon leaves, thereby increasing the heating area of ​​the cinnamon leaves and better improving the efficiency of heating and purification. At the same time, the method of adding oil to the connecting cavity also better realizes that the entire spiral cavity can heat the cinnamon leaves.

[0014] Optionally, a first control valve is provided at the oil inlet, and a second control valve is provided at the oil outlet; the spiral plate includes a rigid portion and a flexible portion; both the rigid portion and the flexible portion are used to form the spiral cavity; the flexible portion can deform to bulge outward or recess inward relative to the rigid portion; when the first control valve and the second control valve make the oil inlet flow greater than the oil outlet flow, the flexible portion deforms to bulge outward relative to the rigid portion; when the first control valve and the second control valve make the oil inlet flow less than the oil outlet flow, the flexible portion deforms to recess inward relative to the rigid portion.

[0015] By adopting the above technical solution, the first control valve and the second control valve control the flow rates of the oil inlet and the oil outlet, and the flexible portion is configured to bulge outward and recess inward. When the cinnamon leaf moves through the spiral cavity, the cinnamon leaf moves to the flexible portion and is subjected to an external force from the bulge of the flexible portion, so that the cinnamon leaf is pushed, and the cinnamon leaf is more evenly contacted with the inner wall surface of the spiral cavity, thereby better improving the effect of heating and purifying the cinnamon leaf.

[0016] Optionally, a connecting spiral tube is provided on the edge of the spiral plate; the connecting spiral tube is used to communicate with the spiral cavity; the connecting spiral tube protrudes upward or downward relative to the upper end surface or the lower end surface of the spiral cavity.

[0017] By adopting the above technical solution, the setting of the connecting spiral tube is mainly to form a limit at the edge of the spiral cavity. The setting of the spiral tube protruding upward or downward relative to the upper end surface or the lower end surface of the spiral cavity can prevent the cinnamon leaves in the spiral cavity from being directly thrown out by the centrifugal force of the rotation of the spiral cavity, so that the cinnamon leaves in the spiral cavity can all move from the bottom of the spiral cavity to the top of the spiral cavity, so that the cinnamon leaves are evenly distributed in the reaction chamber and evenly heated, thereby improving the purification effect.

[0018] Optionally, a heating spiral tube is provided in the reaction chamber; the pitch of the heating spiral tube matches the pitch of the connecting threaded tube; the distance between the connecting threaded tube and the starting end of the heating threaded tube is 0.2-0.8 of the pitch of the heating tube.

[0019] Optionally, the heating spiral tube and the connecting spiral tube constitute a heating chamber for heating and purifying cinnamon leaves; the reaction chamber is composed of the heating chamber and a control chamber; the control chamber is located above the heating chamber; the pressure relief structure includes: a movable plate and a displacement driving component; the movable plate abuts against the inner wall surface of the control chamber; the displacement driving component is used to drive the movable plate to move up and down; when the movable plate moves up, a pressure relief chamber is formed above the spiral plate to allow the cinnamon leaves to be unloaded from the spiral cavity; when the movable plate moves down, the movable plate is connected to the spiral cavity, so that the cinnamon leaves are squeezed when they move to the movable plate.

[0020] By adopting the above technical solution, the movable plate moves up and down, so that the cinnamon leaves are squeezed when they are transported to the top of the spiral cavity, which is more conducive to changing the state of the cinnamon leaves and squeezing out the unheated parts inside. However, if the cinnamon leaves are constantly squeezed, it will affect the movement of the cinnamon leaves in the spiral cavity and affect the efficiency of cinnamon aldehyde purification by the cinnamon leaves. When the movable plate moves up, the top of the spiral cavity is directly connected to the reaction chamber, so that the cinnamon leaves can be directly moved to the bottom along the blanking chamber, thereby improving the purification efficiency of the cinnamon leaves.

[0021] Optionally, the cinnamaldehyde purification device also includes: a vacuum control component; the vacuum control component is used to evacuate the reaction chamber to a vacuum state; the movable plate abuts and seals the inner wall surface of the control chamber; when the movable plate moves downward, the vacuum control component evacuates the reaction chamber to a vacuum state, and then the movable plate moves upward to increase the volume of the reaction chamber.

[0022] By adopting the above-mentioned technical solution, the movable plate can be first moved downward, and the volume available in the reaction chamber becomes smaller, and then the reaction chamber is evacuated using the vacuum control member. After evacuating the vacuum, the movable plate is moved upward, which further increases the degree of vacuum, thereby helping to better ensure the vacuum state of the reaction chamber. Since in some cases, vacuum is difficult to maintain for a long time, negative pressure is generally used to replace vacuum. Therefore, the movable plate can be moved upward and downward for a long time, and after the movable plate is moved downward, vacuum is started, and then the movable plate is moved upward again to achieve a long-term automatic maintenance of the vacuum state of the reaction chamber, thereby better improving the efficiency of cinnamaldehyde purification.

[0023] A method for purifying cinnamaldehyde using the cinnamaldehyde purification device comprises: adding cinnamon leaves into a reaction chamber in a vacuum state; a driving member drives a heating member to rotate, so that a spiral cavity rotates, and the cinnamon leaves are transported in the spiral cavity; after the cinnamon leaves are transported to the top of the spiral cavity, they fall along the connecting cavity to the bottom of the spiral cavity, and the cinnamon leaves are repeatedly moved in the spiral cavity.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The spiral cavity formed by the spiral plate is used to transport the cinnamon leaves, so that the cinnamon leaves are in a state of movement in the reactor. The spiral cavity then heats the cinnamon leaves in contact, thereby increasing the area of ​​heating of the cinnamon leaves. The transportation of the cinnamon leaves will cause the cinnamon leaves to roll, further increasing the heating area.

[0026] 2. Contact heating under vacuum state is used to heat the cinnamon leaves. The cinnamon leaves will not come into contact with any air, and thus the cinnamic aldehyde will not come into contact with any air, thereby avoiding the reaction between cinnamic aldehyde and air, resulting in low purity and efficiency of cinnamic aldehyde purification.

[0051] The following is combined with Figure 1-17 This application is described in further detail.

[0052] The embodiments of the present application disclose a cinnamaldehyde purification device and method. Example 1

[0053] Refer to the attached Figure 1-14 17. This embodiment provides a cinnamaldehyde purification device for obtaining cinnamaldehyde from cinnamon leaves. The purification device includes a reactor 1, a heating element 2, and a driving element 3.

[0054] Reactor 1 is used to form a vacuum reaction chamber 11. A heating element 2 is disposed within reaction chamber 11 and, together with reaction chamber 11, forms a spiral cavity 21 for accommodating the high-temperature cinnamon leaves. In this embodiment, heating element 2 is a block having spiral cavity 21. Electrical heating is used to increase the temperature of heating element 2, thereby heating the inner wall of spiral cavity 21. Reactor 1 is provided with a feed inlet and a discharge inlet. Both the feed inlet and the discharge inlet are connected to the chamber.

[0055] The driving member 3 is used to drive the heating member 2 to rotate, thereby rotating the spiral cavity 21 and driving the cinnamon leaves to move in the spiral cavity 21. The driving member 3 adopts a driving motor, or a combination of a driving motor and a belt drive structure 31, or a combination of a driving motor and a chain drive. A plurality of material transport cavities 12 are formed on the reaction chamber 11; the inner wall surface of the reaction chamber 11 coincides with the edge of the spiral cavity 21, and the material transport cavities 12 are recessed relative to the inner wall surface of the reaction chamber 11 away from the spiral cavity 21. Specifically, the reaction chamber 11 is a vertical cylindrical cavity, and the material transport cavities 12 are vertically opened on the reaction chamber 11. The material transport cavities 12 are connected to the spiral cavity 21. The heating member 2 can also be used to heat the reactor 1. The heating member 2 can heat the reactor 1 by electric heating, so that the inner wall surface of the reaction chamber 11 and the inner wall surface of the material transport cavities 12 are in a high temperature state. Because the edge of the spiral cavity 21 coincides with the inner wall of the reaction chamber 11, the cinnamon leaves in the spiral cavity 21 cannot fall downward from the edge of the spiral cavity 21. However, through the provision of the material transport cavity 12, when the cinnamon leaves on the spiral cavity 21 move to the position where the spiral cavity 21 and the material transport cavity 12 are connected, the cinnamon leaves can move along the material transport cavity 12 to the bottom of the reaction chamber 11 and then be transported upward by the spiral cavity 21. This can reduce the number of cinnamon leaves falling out of the spiral cavity 21, so that the cinnamon leaves are mainly transported and heated by the spiral cavity 21. The material transport cavity 12 is mainly used to return the cinnamon leaves to the bottom of the spiral cavity 21 after they move to the top of the spiral cavity 21.

[0056] By adopting above-mentioned technical scheme, contact heating under vacuum state, cinnamon leaf is heated, thereby cinnamon leaf is in the process of obtaining cinnamaldehyde by heating, cinnamon leaf can not contact with any air, thereby cinnamaldehyde can not contact with any air, thereby avoid cinnamaldehyde and air generation reaction and cause the purity and the problem of low efficiency of cinnamaldehyde purification.Utilize the rotation of spiral cavity 21 in addition, cinnamon leaf is moved in spiral cavity 21, thereby cinnamon leaf can be rolled in the process of moving, cinnamon leaf is heated more evenly, ensure the efficiency of cinnamon leaf purification.And the arrangement of material transport cavity 12 is when cinnamon leaf moves to the top of spiral cavity 21, can fall downwards, then again move in spiral cavity 21, thereby realize cinnamon leaf continuous moving and rolling in the process of moving, better ensure the efficiency of cinnamon leaf purification of cinnamaldehyde.

[0057] Specifically, the bottom surface of the reaction chamber 11 forms a collecting structure 4, which is used to collect cinnamon leaves in the middle of the reaction chamber 11. A spiral cavity 21 is formed in the middle of the reaction chamber 11 to allow the cinnamon leaves collected in the middle of the reaction chamber 11 to move into the spiral cavity 21. After being collected, the cinnamon leaves can be more easily moved back into the spiral cavity 21, ensuring that the cinnamon leaves are continuously transported in the spiral cavity 21, improving the uniformity of the heating of the cinnamon leaves and ensuring the efficiency of purification.

[0058] The collecting structure 4 is a concave curved surface 41 provided on the bottom surface of the reaction chamber 11, allowing the cinnamon leaves to fall along the concave curved surface 41 into the center of the reaction chamber 11. Alternatively, the collecting structure 4 can be a concave inclined surface provided on the bottom surface. The concave curved surface can be used to collect the purified cinnamaldehyde.

[0059] Specifically, a pressure relief structure 5 is formed on the top surface of the reaction chamber 11, which is used to disperse the cinnamon leaves above the spiral cavity 21 to the edge of the spiral cavity 21. This prevents the cinnamon leaves from being squeezed after moving to the top of the spiral cavity 21, making it difficult for the cinnamon leaves to fall down in time.

[0060] In this embodiment, the pressure relief structure 5 is formed by forming a protruding convex surface 51 on the top surface of the reaction chamber 11. The convex surface 51 may be conical. When the cinnamon leaves move to the top of the spiral cavity 21, the conical convex surface 51 guides the cinnamon leaves toward the edge of the spiral cavity 21, causing them to escape from the spiral cavity 21 and fall along the material transport cavity 12 to the bottom of the spiral cavity 21. This ensures that the cinnamon leaves fall smoothly from the material transport cavity 12.

[0061] Specifically, the heating element 2 includes a rotating shaft 22, a spiral plate 23, and a heating structure 24. The spiral plate 23 is fixed to the rotating shaft 22. An oil inlet 221 is formed at one end of the rotating shaft 22, and an oil outlet 222 is formed at the other end. A connecting cavity 233, shaped to match the spiral cavity 21, is formed in the spiral plate 23. The connecting cavity 233 connects the oil inlet 221 and the oil outlet 222. The heating structure 24 is used to add highly heated oil to the connecting cavity 233 through the oil inlet 221 and discharge it through the oil outlet 222. When the high-temperature oil is introduced into the connecting cavity 233, it exchanges heat with the spiral plate 23, thereby raising the temperature of the spiral plate 23. The cinnamon leaves come into contact with the spiral plate 23, thereby heating the cinnamon leaves. In this embodiment, the spiral plate 23 forms the spiral cavity 21. The heating structure 24 comprises an oil pump 241, an oil pipeline 242, and a heating element 243. The oil delivery pipe 242, the oil pump 241, the oil inlet 221, the connecting cavity 233 and the oil outlet 222 form a closed loop, and the closed loop is filled with oil. The heating component 243 is used to heat the oil in the closed loop, and the heating component 243 uses a heating pipe for heating.

[0062] More specifically, a first control valve is provided at the oil inlet 221, and a second control valve is provided at the oil outlet 222. The spiral plate 23 includes a rigid portion 231 and a flexible portion 232. Both the rigid portion 231 and the flexible portion 232 are used to form the spiral cavity 21. The flexible portion 232 can deform to bulge outward or sink inward relative to the rigid portion 231. When the first control valve and the second control valve make the flow rate of the oil inlet 221 greater than the flow rate of the oil outlet 222, the flexible portion 232 deforms to bulge outward relative to the rigid portion 231. When the first control valve and the second control valve make the flow rate of the oil inlet 221 less than the flow rate of the oil outlet 222, the flexible portion 232 deforms to sink inward relative to the rigid portion 231. Among them, the rigid portion 231 is made of metal, and the flexible portion 232 is made of high-temperature resistant rubber. More specifically, the spiral plate 23 and the rotating shaft 22 are fixed as a whole, and the spiral plate 23 and the rotating shaft 22 are separated from the axis into two cast parts, and then the two cast parts are docked and fixed together to obtain a complete spiral plate 23 and rotating shaft 22. A notch is provided on the spiral plate 23, and a flexible portion 232 is provided on the notch. The flexible portion 232 closes the notch, and the notch is connected to the connecting cavity 233. The first control valve and the second control valve control the flow of the oil inlet 221 and the oil outlet 222, so that the flexible portion 232 is protruded outwardly and recessed inwardly. When the cinnamon leaf moves through the spiral cavity 21, it moves to the flexible portion 232 and is subjected to the external force of the protrusion of the flexible portion 232, so that the cinnamon leaf is pushed, so that the cinnamon leaf is more evenly contacted with the inner wall surface of the spiral cavity, and the effect of heating and purifying the cinnamon leaf is better. Example 2

[0063] Refer to the attached Figure 7-14 The difference between this embodiment and embodiment 1 is that a connecting spiral tube 6 is provided on the edge of the spiral plate 23. The connecting spiral tube 6 is used to communicate with the spiral cavity 21. The connecting spiral tube 6 protrudes upward or downward relative to the upper end face or lower end face of the spiral cavity 21. The setting of the connecting spiral tube 6 is mainly to form a limit at the edge of the spiral cavity 21. The setting of the spiral tube protruding upward or downward relative to the upper end face or lower end face of the spiral cavity 21 can prevent the cinnamon leaves in the spiral cavity 21 from being directly thrown out by the centrifugal force of the rotation of the spiral cavity 21, so that the cinnamon leaves in the spiral cavity 21 can all move from the bottom of the spiral cavity 21 to the top of the spiral cavity 21, so that the cinnamon leaves are evenly distributed in the reaction chamber 11 and are evenly heated, thereby improving the purification effect.

[0064] Specifically, a heating coil 7 is installed in the reaction chamber 11. The pitch of the heating coil 7 matches the pitch of the connecting threaded tube; the distance between the connecting threaded tube and the starting point of the heating coil is 0.2-0.8 times the pitch of the heating coil. This arrangement allows the space at the edge of the spiral cavity 21 not completely blocked by the connecting threaded tube 6 to contact the heating coil 7, completely or partially blocking this area. This greatly increases the area of ​​the cinnamon leaves heated and improves the heating and purification effect.

[0065] The heating spiral tube 7 forms the inner wall surface of the reaction chamber 11 , and the blanking chamber is opened on the heating spiral tube 7 .

[0066] The heating coil 7 generates heat by electric heating, or the heating coil 7 is fixedly connected to the rotating shaft 22, so that the heating coil 7 is connected to the connecting cavity 233, so that the oil in the rotating shaft 22 flows into the heating coil 7, causing the heating coil 7 to generate heat. Example 3

[0067] Refer to the attached Figure 7-15The difference between this embodiment and embodiment 2 is that the heating spiral tube 7 and the connecting spiral tube 6 form a heating chamber 111 for heating and purifying cinnamon leaves. The reaction chamber 11 is composed of a heating chamber 111 and a control chamber 112. The control chamber 112 is located above the heating chamber 111. The pressure relief structure 5 is arranged in the control chamber 112, and the pressure relief structure 5 includes: a moving plate 52 and a displacement driving component 53. The moving plate 52 is used to form the conical convex surface 51 of embodiment 1. The moving plate 52 abuts against the inner wall surface of the control chamber 112. The displacement driving component 53 is used to drive the moving plate 52 to move up and down, and the displacement driving component 53 is one of a cylinder, a hydraulic cylinder and an electric push rod. When the moving plate 52 moves up, a pressure relief chamber is formed above the spiral plate 23 to allow the cinnamon leaves to be unloaded from the spiral cavity 21. When the movable plate 52 moves downward, it contacts the spiral cavity 21, so that the cinnamon leaves are squeezed when they move to the movable plate 52. When the movable plate 52 moves downward, it moves to the lowest position, and the cinnamon leaves come into contact with the conical convex surface 51. At this time, the position of the conical convex surface 51 is lower than that of the conical convex surface 51 in Example 1, so the cinnamon leaves are squeezed when they move to the movable plate 52. The upward and downward movement of the movable plate 52 can squeeze the cinnamon leaves when they are transported to the top of the spiral cavity 21, which is more conducive to changing the state of the cinnamon leaves and squeezing out the unheated parts inside. However, if the cinnamon leaves are constantly squeezed, it will affect the movement of the cinnamon leaves in the spiral cavity 21 and affect the efficiency of purifying cinnamaldehyde from the cinnamon leaves. Therefore, when the movable plate 52 moves upward, the top of the spiral cavity 21 is directly connected to the reaction chamber 11, and the cinnamon leaves can be directly moved to the bottom along the blanking chamber, thereby improving the purification efficiency of the cinnamon leaves. Example 4

[0068] Refer to the attached Figure 1-16The difference between this embodiment and embodiment 3 is that the cinnamaldehyde purification device further includes a vacuum control component 8. The vacuum control component 8 is used to evacuate the reaction chamber 11 to a vacuum state. The vacuum control component 8 adopts a vacuum pump, which is connected to the reaction chamber 11. The vacuum pump is used to remove the air in the reaction chamber 11. A valve is provided at the position where the vacuum pump is connected to the reaction chamber 11. The connection between the vacuum pump and the reaction chamber 11 is controlled by closing and opening the valve. After the vacuum pump removes the air from the reaction chamber 11, the valve is closed to disconnect the vacuum pump from the reaction chamber 11, thereby better ensuring the vacuum state of the reaction chamber 11. The movable plate 52 is in contact and sealed with the inner wall surface of the control chamber 112. When the movable plate 52 moves downward, the vacuum control component 8 evacuates the reaction chamber 11 to a vacuum state, and then the movable plate 52 moves upward to increase the volume of the reaction chamber 11. More precisely, after the movable plate 52 moves to its lowest position and stops, the vacuum control unit 8 evacuates the reaction chamber 11 to a vacuum state. The movable plate 52 then moves upward to its highest position. The volume of the reaction chamber 11 increases accordingly, referring to the volume of the reaction chamber 11 below the movable plate 52. This better ensures a vacuum state. The movable plate 52 can be first moved downward, reducing the available volume of the reaction chamber 11. The vacuum control unit 8 can then be used to evacuate the reaction chamber 11. After the vacuum is evacuated, the movable plate 52 is moved upward, further increasing the degree of vacuum, thereby helping to better ensure the vacuum state of the reaction chamber 11. Because vacuum is difficult to maintain for long periods of time in some cases, negative pressure is generally used instead. Therefore, the movable plate 52 can be moved upward and downward for extended periods of time. After the movable plate 52 moves downward, vacuuming begins, and then the movable plate 52 is moved upward again to automatically maintain the vacuum state of the reaction chamber 11 for extended periods of time, thereby further improving the efficiency of cinnamaldehyde purification.

[0069] In some embodiments, the cinnamaldehyde purification device further includes a fixed bracket for mounting the reaction kettle 1 , the vacuum control component 8 , the driving component 3 , the oil pump 241 and the displacement driving component 53 . Example 5

[0070] This embodiment provides a method for purifying cinnamaldehyde using the cinnamaldehyde purification device of the above-mentioned embodiments 1-4, comprising the following steps: adding cinnamon leaves to a reaction chamber 11 in a vacuum state; driving the heating element 2 to rotate the spiral cavity 21 by the driving member 3, thereby rotating the spiral cavity 21 and transporting the cinnamon leaves in the spiral cavity 21; after the cinnamon leaves are transported to the top of the spiral cavity 21, they fall along the connecting cavity 233 to the bottom of the spiral cavity 21, and the cinnamon leaves are repeatedly moved in the spiral cavity 21.

[0071] The implementation principle of a cinnamaldehyde purification device and method in the embodiment of the present application is as follows:

[0072] Cinnamon leaves are put into the reaction chamber 11 of the reactor 1 , and the cinnamon leaves mainly fall into the spiral cavity 21 .

[0073] The oil pump 241 circulates the oil between the oil inlet 221, the connecting cavity 233, the oil outlet 222 and the oil pipe 242. The heating component 243 heats the oil in the oil pipe 242. The heated oil exchanges heat with the spiral plate 23, causing the spiral plate 23 to heat up, and then the spiral cavity 21 to heat up, so that the spiral cavity 21 is in a high temperature state, wherein the high temperature state of the spiral cavity 21 is 100-150°C.

[0074] The driving member 3 drives the rotating shaft 22 to rotate, thereby rotating the rotating shaft 22 and the spiral plate 23, and then causing the spiral cavity 21 to rotate accordingly, so that the cinnamon leaves are transported upward in the spiral cavity 21. After the cinnamon leaves are transported to the top of the spiral cavity 21, the cinnamon leaves move toward the edge of the spiral cavity 21, so that the cinnamon leaves move into the diversion cavity 12, and then the cinnamon leaves move along the cavity 12 to the bottom of the spiral cavity 21, so that the cinnamon leaves enter the spiral cavity 21 again, thereby realizing the reciprocating transportation of the cinnamon leaves from bottom to top.

[0075] The first control valve at the oil inlet 221 and the second control valve at the oil outlet 222 control the speed of oil inlet and oil outlet. When the oil inlet flow rate is greater than the oil outlet flow rate, the pressure in the connecting cavity 233 increases, causing the flexible portion 232 to bulge upward. The flexible portion 232 pushes the cinnamon on the spiral cavity 21 to flip, increasing the degree of contact between the cinnamon leaves and the spiral cavity 21, increasing the heating area of ​​the cinnamon leaves and the uniformity of the heating.

[0076] After the cinnamon leaves are placed in the reaction chamber 11, the movable plate 52 moves downward to its lowest position. The vacuum pump evacuates the reaction chamber 11. The valve closes to disconnect the vacuum pump from the reaction chamber 11. The movable plate 52 then moves upward to its highest position. While the spiral channel 21 heats and transports the cinnamon leaves, the movable plate 52 moves downward to its lowest position. The valve opens, and the vacuum pump again evacuates the reaction chamber 11. The movable plate 52 then moves upward to its highest position.

[0077] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
