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, cinnamaldehyde reacts with the gas in the steam, which ultimately leads to a very low yield of cinnamaldehyde and low efficiency in purifying cinnamaldehyde.

[0003] However, the 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: A cinnamaldehyde purification device, which 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, which is used to drive the heating element to rotate so that the spiral cavity rotates and drives 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 away from the spiral cavity relative to the inner wall surface of the reaction chamber; 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.

[0006] By adopting the above-mentioned technical scheme, contact heating under vacuum state heats up cinnamon leaf, so that in the process of heating cinnamon leaf to obtain cinnamaldehyde, cinnamon leaf will not contact with any air, so cinnamaldehyde will not contact with any air, so as to avoid cinnamaldehyde and air reaction leading to the purity and inefficiency of cinnamaldehyde purification. In addition, the rotation of spiral cavity is utilized to move cinnamon leaf in spiral cavity, so that cinnamon leaf can roll during the moving process, so that cinnamon leaf is heated more evenly, and the efficiency of cinnamon leaf purification is guaranteed. And the arrangement of the transport cavity is that when cinnamon leaf moves to the top of spiral cavity, it can fall downward, and then move again in spiral cavity, so as to realize the continuous movement of cinnamon leaf and rolling during the moving process, and better guarantee the efficiency of cinnamon leaf purification of cinnamaldehyde.

[0007] 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 to the middle of the reaction chamber can move into the spiral cavity.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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 whose shape matches 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.

[0012] 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, and the cinnamon leaves are in contact with the spiral plate to achieve heating of the cinnamon leaves, and 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 into the connecting cavity also better realizes that the entire spiral cavity can heat the cinnamon leaves.

[0013] 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; the rigid portion and the flexible portion are both 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 rate greater than the oil outlet flow rate, 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 rate less than the oil outlet flow rate, the flexible portion deforms to recess inward relative to the rigid portion.

[0014] By adopting the above technical solution, the first control valve and the second control valve control the flow of the oil inlet and the oil outlet, so that the flexible part is convex outward and concave inward, when the cinnamon leaves move through the spiral cavity, the cinnamon leaves can be moved to the flexible part and the cinnamon leaves are subjected to the external force of the convex flexible part, so that the cinnamon leaves are pushed, and the cinnamon leaves are more evenly contacted with the inner wall surface of the spiral cavity, so as to better improve the effect of heating and purifying the cinnamon leaves.

[0015] 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.

[0016] 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 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.

[0017] Optionally, a heating spiral tube is arranged 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.

[0018] 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 moving plate and a displacement driving component; the moving plate abuts against the inner wall surface of the control chamber; the displacement driving component is used to drive the moving plate to move up and down; when the moving 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 moving plate moves down, the moving plate is connected to the spiral cavity to allow the cinnamon leaves to be squeezed when they move to the moving plate.

[0019] By adopting the above technical solution, the movable plate moves up and down, so that when the cinnamon leaves are transported to the top of the spiral cavity in the spiral cavity, the cinnamon leaves are squeezed, which is more conducive to changing the state of the cinnamon leaves and squeezing out the unheated parts inside. However, the cinnamon leaves are always squeezed, which affects the movement of the cinnamon leaves in the spiral cavity and affects the efficiency of purifying cinnamaldehyde from 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.

[0020] 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 against 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.

[0021] By adopting the above technical solution, the movable plate can be moved down first, and the available volume of the reaction chamber becomes smaller at this time, and then the reaction chamber is evacuated by the vacuum control member. After the vacuum is evacuated, the movable plate is moved up, which will further increase the degree of vacuum, thereby helping to better ensure the vacuum state of the reaction chamber. Since in some cases, the vacuum is difficult to maintain for a long time, generally, the vacuum is replaced by negative pressure, so the movable plate can be moved up and down for a long time, and after the movable plate is moved down, vacuum is started, and then the movable plate is moved up again to achieve automatic maintenance of the vacuum state of the reaction chamber for a long time, so as to better improve the efficiency of cinnamaldehyde purification.

[0022] A method for purifying cinnamaldehyde using the above-mentioned 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.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. The spiral cavity formed by the spiral plate is used to transport the cinnamon leaves, so that the cinnamon leaves are in a moving state in the reactor, and then the spiral cavity will contact and heat the cinnamon leaves, thereby increasing the heating area of ​​the cinnamon leaves. The transportation of the cinnamon leaves will cause the cinnamon leaves to roll, further increasing the heating area; 2. Contact heating under vacuum state is used to heat up the cinnamon leaves. The cinnamon leaves will not come into contact with any air, and thus cinnamaldehyde will not come into contact with any air, thereby avoiding the reaction between cinnamaldehyde and air, resulting in low purity and efficiency of cinnamaldehyde purification.

[0026] The following is combined with Figure 1-17 This application is described in further detail.

[0027] The embodiments of the present application disclose a cinnamaldehyde purification device and method. Example 1

[0028] See attached Figure 1-14 17. This embodiment provides a cinnamaldehyde purification device, which is used to obtain cinnamaldehyde using cinnamon leaves as raw materials. The purification device includes: a reaction kettle 1, a heating element 2 and a driving element 3.

[0029] The reactor 1 is used to form a reaction chamber 11 in a vacuum state. The heating element 2 is arranged in the reaction chamber 11, and together with the reaction chamber 11, forms a spiral cavity 21 for accommodating cinnamon leaves in a high temperature state. In this embodiment, the heating element 2 is a block having a spiral cavity 21, and the heating element 2 is heated by electric heating, so that the inner wall surface of the spiral cavity 21 is heated. A feeding port and a discharging port are provided on the reactor 1. Both the feeding port and the discharging port are connected to the cavity.

[0030] The driving member 3 is used to drive the heating member 2 to rotate, so that the spiral cavity 21 rotates and drives 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. Among them, 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 cavity 12 is recessed away from the spiral cavity 21 relative to the inner wall surface of the reaction chamber 11. Specifically, the reaction chamber 11 is a vertical cylindrical cavity, and the material transport cavity 12 is opened on the reaction chamber 11 in the vertical direction. The material transport cavity 12 is 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 cavity 12 are in a high temperature state. Since 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 down from the edge of the spiral cavity 21. However, through the setting 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, thereby reducing 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.

[0031] By adopting the above-mentioned technical scheme, contact heating under vacuum state heats up cinnamon leaf, so that in the process of heating cinnamon leaf to obtain cinnamaldehyde, cinnamon leaf will not contact with any air, so cinnamaldehyde will not contact with any air, so as to avoid cinnamaldehyde and air reaction leading to the purity and inefficiency of cinnamaldehyde purification. In addition, the rotation of spiral cavity 21 is utilized to move cinnamon leaf in spiral cavity 21, so that cinnamon leaf can roll during the moving process, so that cinnamon leaf is heated more evenly, and the efficiency of cinnamon leaf purification is guaranteed. And the arrangement of material transport cavity 12 is that when cinnamon leaf moves to the top of spiral cavity 21, it can fall downwards, and then move again in spiral cavity 21, so as to realize the continuous movement of cinnamon leaf and rolling during the moving process, and better guarantee the efficiency of cinnamon leaf purification of cinnamaldehyde.

[0032] Specifically, the bottom surface of the reaction chamber 11 forms a collecting structure 4; the collecting structure 4 is used to collect the cinnamon leaves to the middle of the reaction chamber 11; the spiral cavity 21 is formed in the middle of the reaction chamber 11, so that the cinnamon leaves collected in the middle of the reaction chamber 11 move to the spiral cavity 21. After being collected, the cinnamon leaves can be better moved to the spiral cavity 21 again, ensuring that the cinnamon leaves can be continuously transported in the spiral cavity 21, improving the uniform heating of the cinnamon leaves to ensure the efficiency of purification.

[0033] The collecting structure 4 is a concave curved surface 41 provided on the bottom surface of the reaction chamber 11, so that the cinnamon leaves can fall into the middle of the reaction chamber 11 along the concave curved surface 41. In addition, the collecting structure 4 can also be a concave inclined surface provided on the bottom surface. The concave curved surface can be used to accommodate the purified cinnamaldehyde.

[0034] Specifically, a pressure relief structure 5 is formed on the top surface of the reaction chamber 11, and the pressure relief structure 5 is used to disperse the cinnamon leaves on the upper part of the spiral cavity 21 to the edge of the spiral cavity 21. This prevents the cinnamon leaves from being squeezed after moving to the upper part of the spiral cavity 21, making it difficult for the cinnamon leaves to fall down in time.

[0035] The pressure relief structure 5 in this solution forms a protruding convex surface 51 on the top surface of the reaction chamber 11, which can be a conical convex surface 51, so that when the cinnamon leaves move to the top of the spiral cavity 21, the cinnamon leaves can be guided by the conical convex surface 51, and the cinnamon leaves are diverted to the edge of the spiral cavity 21, so that the cinnamon leaves are separated from the spiral cavity 21 and fall to the bottom of the spiral cavity 21 along the material transport cavity 12. The cinnamon leaves fall smoothly from the material transport cavity 12.

[0036] 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 whose shape matches the spiral cavity 21 is formed in the spiral plate 23. The connecting cavity 233 is used to connect the oil inlet 221 and the oil outlet 222. The heating structure 24 is used to add the oil in a high-heat state to the connecting cavity 233 through the oil inlet 221 and discharge it through the oil outlet 222. The high-temperature oil is passed into the connecting cavity 233, and then the high-temperature oil will exchange heat with the spiral plate 23, thereby increasing the temperature of the spiral plate 23, and the cinnamon leaves will contact the spiral plate 23, so as to achieve the heating of the cinnamon leaves. In this embodiment, the spiral plate 23 forms a spiral cavity 21. The heating structure 24 uses an oil pump 241, an oil pipeline 242 and a heating component 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 is heated by a heating pipe.

[0037] More specifically, the oil inlet 221 is provided with a first control valve, and the oil outlet 222 is provided with a second control valve. 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 to be recessed 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 is deformed 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 is deformed to be recessed 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 fixed together to obtain a complete spiral plate 23 and the rotating shaft 22. A notch is provided on the spiral plate 23, and a flexible part 232 is provided on the notch, and the flexible part 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 part 232 is convex outward and concave inward, so that when the cinnamon leaf moves through the spiral cavity 21, the cinnamon leaf moves to the flexible part 232 and the cinnamon leaf is subjected to the external force of the convex part 232, so that the cinnamon leaf is pushed, so that the cinnamon leaf is better and more evenly contacted with the inner wall surface of the spiral chamber, and the effect of heating and purifying the cinnamon leaf is better improved. Example 2

[0038] See attached Figure 7-14 , the difference between this embodiment and embodiment 1 is that: a connecting spiral tube 6 is provided at 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 surface or the lower end surface 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 surface or the lower end surface 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.

[0039] Specifically, a heating spiral tube 7 is arranged in the reaction chamber 11. The pitch of the heating spiral tube 7 matches the pitch of the connecting threaded tube; the starting end of the connecting threaded tube and the heating spiral tube is 0.2-0.8 pitches of the heating tube. Such an arrangement can make the space at the edge of the spiral cavity 21 that is not completely blocked by the connecting spiral tube 6 contact with the heating spiral tube 7, and the heating spiral tube 7 completely or partially blocks this part, thereby greatly increasing the area of ​​the cinnamon leaves being heated and improving the effect of heating and purification.

[0040] 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 .

[0041] The heating spiral tube 7 generates heat by electric heating, or the heating spiral tube 7 is fixedly connected to the rotating shaft 22, so that the heating spiral tube 7 is connected to the connecting cavity 233, so that the oil in the rotating shaft 22 flows into the heating spiral tube 7, so that the heating spiral tube 7 generates heat. Example 3

[0042] See 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 moving plate 52 moves downward, the moving plate 52 is connected to the spiral cavity 21, so that the cinnamon leaves are squeezed when they move to the moving plate 52. When the moving plate 52 moves downward, the moving plate 52 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 moving plate 52. The movable plate 52 moves up and down, so that when the cinnamon leaves are transported to the top of the spiral cavity 21 in the spiral cavity 21, the cinnamon leaves are squeezed, which is more conducive to changing the state of the cinnamon leaves and squeezing out the unheated parts inside. However, the cinnamon leaves are always squeezed, which affects the movement of the cinnamon leaves in the spiral cavity 21 and the efficiency of purifying cinnamaldehyde from the cinnamon leaves. Then, when the movable plate 52 moves up, the top of the spiral cavity 21 is directly connected to the reaction chamber 11, 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. Example 4

[0043] See attached Figure 1-16, the difference between this embodiment and embodiment 3 is that: the cinnamaldehyde purification device also includes a vacuum control part 8. The vacuum control part 8 is used to evacuate the reaction chamber 11 to a vacuum state. The vacuum control part 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, wherein a valve is provided at the position where the vacuum pump is connected to the reaction chamber 11, and whether the vacuum pump is connected to 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, so as to better ensure the vacuum state of the reaction chamber 11. The movable plate 52 is sealed against the inner wall surface of the control chamber 112. When the movable plate 52 moves downward, the vacuum control part 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. To be precise, the movable plate 52 stops after moving to the lowest position, and then the vacuum control part 8 draws the reaction chamber 11 to a vacuum state, and then the movable plate 52 moves up to the highest position, and the volume of the reaction chamber 11 will increase accordingly, which refers to the volume of the reaction chamber 11 below the movable plate 52, so that the vacuum state is better guaranteed. The movable plate 52 can be moved down first, and the volume that can be used by the reaction chamber 11 becomes smaller, and then the vacuum control part 8 is used to evacuate the reaction chamber 11. After the vacuum is evacuated, the movable plate 52 moves up, which will further increase the degree of vacuum, so as to better ensure the vacuum state of the reaction chamber 11. In some cases, the vacuum is difficult to maintain for a long time, and generally the vacuum is replaced by negative pressure, so the movable plate 52 can be moved up and down for a long time, and after the movable plate 52 moves down, vacuum is started, and then the movable plate 52 moves up again to realize the automatic maintenance of the vacuum state of the reaction chamber 11 for a long time, so as to better improve the efficiency of cinnamaldehyde purification.

[0044] In some embodiments, the cinnamaldehyde purification device further comprises a fixed bracket, which is used to install 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

[0045] The present 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 into a reaction chamber 11 in a vacuum state; the driving member 3 drives the heating member 2 to rotate so that the spiral cavity 21 rotates, and the cinnamon leaves are transported in the spiral cavity 21; after the cinnamon leaves are transported to the top of the spiral cavity 21, they fall to the bottom of the spiral cavity 21 along the connecting cavity 233, and the cinnamon leaves are repeatedly moved in the spiral cavity 21.

[0046] The implementation principle of a cinnamaldehyde purification device and method in the present application embodiment is as follows: The cinnamon leaves are put into the reaction chamber 11 of the reaction kettle 1 , and the cinnamon leaves mainly fall into the spiral cavity 21 .

[0047] The oil pump 241 allows the oil to circulate 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, so that the spiral plate 23 is heated, and then the spiral cavity 21 is heated, 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.

[0048] 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 to the edge of the spiral cavity 21, so that the cinnamon leaves move into the guide material transport cavity 12, and then the cinnamon leaves move along the material transport 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.

[0049] 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 flow rate of oil inlet is greater than the flow rate of oil outlet, the pressure of 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, thereby increasing the degree of contact between the cinnamon leaves and the spiral cavity 21, and increasing the heating area of ​​the cinnamon leaves and the uniformity of heating.

[0050] After the cinnamon leaves are put into the reaction chamber 11, the movable plate 52 moves downward to the lowest position, the vacuum pump evacuates the reaction chamber 11, the valve is closed to disconnect the vacuum pump from the reaction chamber 11, and then the movable plate 52 moves upward to the highest position. During the process of the spiral cavity 21 heating and conveying the cinnamon leaves, the movable plate 52 moves downward to the lowest position, the valve is opened, and then the vacuum pump evacuates the reaction chamber 11 again, and then the movable plate 52 moves upward to the highest position.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
