Description

Technical Field

[0001] The invention relates to the technical field of preparing patchouli volatile oil, and in particular to a method for preparing patchouli volatile oil. Background Art

[0002] Patchouli is the dried aerial part of the plant genus Echinops in the Lamiaceae family. The whole plant is used as medicine, mainly for the treatment of dampness blocking the middle of the body, abdominal distension and vomiting, fatigue due to summer heat and dampness, chest tightness and discomfort, cold and dampness, abdominal pain, vomiting and diarrhea, and nasal sinusitis and headache. Patchouli is also an important component of more than 30 kinds of Chinese patent medicines, such as "Huoxiang Zhengqi Pills (Water)" and "Huodan Pills".

[0003] The invention patent with authorization announcement number CN 102357117 B discloses patchouli volatile oil, a preparation method and an application thereof in the preparation of anti-tumor drugs. The patchouli volatile oil is prepared by the following method: patchouli medicinal materials are used as raw materials and crushed, and passed through a 40-80 mesh sieve, and 0.5%-4% hemicellulase or cellulase by weight of the raw materials and 10-14 times the weight of distilled water are added. After enzymolysis for 0.5-5 hours at 25-45° C. in a buffer solution of pH 3.5-5.5, the mixture is extracted by distillation for 2-5 hours to obtain patchouli volatile oil, wherein the relative percentage of patchouli alcohol in the patchouli volatile oil is not less than 26.0%, and the relative percentage of patchouli ketone is not less than 30.0%.

[0004] However, after being put into practical use by technicians skilled in the art, it is found that the preparation method of the patchouli volatile oil still has some shortcomings. The most obvious one is that after the patchouli volatile oil is prepared by distillation, it is still necessary to use anhydrous sodium sulfate to dehydrate the patchouli volatile oil. In the prior art, when using anhydrous sodium sulfate to dehydrate the patchouli volatile oil, most of the anhydrous sodium sulfate particles are directly added to the patchouli volatile oil manually. The direct addition method will cause the anhydrous sodium sulfate particles to be deposited at the bottom of the patchouli volatile oil. At the same time, it is also impossible to accurately control the addition amount, which affects the dehydration efficiency and easily causes a waste of anhydrous sodium sulfate. In addition, after the dehydration is completed, the anhydrous sodium sulfate particles in the patchouli volatile oil need to be filtered out. The traditional filtering process is not only time-consuming, but also a small amount of patchouli volatile oil will remain on the surface of the anhydrous sodium sulfate particles, thereby reducing the yield of patchouli volatile oil.

[0005] Therefore, it is necessary to invent a method for preparing patchouli oil volatile oil to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a method for preparing patchouli volatile oil. The method comprises a patchouli volatile oil containing mechanism, a driving mechanism, an anhydrous sodium sulfate supply mechanism, a longitudinal distribution mechanism and a blocking mechanism, so that the driving mechanism is used to drive the anhydrous sodium sulfate supply mechanism to move downward, so that the anhydrous sodium sulfate particles in the anhydrous sodium sulfate supply mechanism enter the longitudinal distribution mechanism, and at the same time, the anhydrous sodium sulfate supply mechanism drives the longitudinal distribution mechanism to rotate, so that the longitudinal distribution mechanism drives the anhydrous sodium sulfate particles in the longitudinal distribution mechanism to dehydrate the patchouli volatile oil in the patchouli volatile oil containing mechanism, and then the driving mechanism drives the blocking mechanism, so that the blocking mechanism blocks the longitudinal distribution mechanism, so that the anhydrous sodium sulfate particles are prevented from entering the longitudinal distribution mechanism when the longitudinal distribution mechanism is reset, and in the subsequent upward reset process of the driving mechanism, the longitudinal distribution mechanism is driven by the anhydrous sodium sulfate supply mechanism to rotate and rise synchronously, so that the residual patchouli volatile oil is thrown out, and at the same time, the patchouli volatile oil is removed from the longitudinal distribution mechanism. The used anhydrous sodium sulfate particles are output, and the blocking mechanism is pushed by the patchouli volatile oil containing mechanism during the resetting process of the longitudinal distribution mechanism, and then reset synchronously, so as to solve the problem proposed in the above background technology that after the patchouli volatile oil is prepared by the distillation method, the patchouli volatile oil needs to be dehydrated by anhydrous sodium sulfate. In the prior art, when the patchouli volatile oil is dehydrated by anhydrous sodium sulfate, most of the anhydrous sodium sulfate particles are directly added to the patchouli volatile oil manually. The direct addition method will cause the anhydrous sodium sulfate particles to be deposited at the bottom of the patchouli volatile oil, and the addition amount cannot be accurately controlled, which affects the dehydration efficiency and easily causes the waste of anhydrous sodium sulfate. In addition, after the dehydration is completed, the anhydrous sodium sulfate particles in the patchouli volatile oil need to be filtered out. The traditional filtering process is not only time-consuming, but also a small amount of patchouli volatile oil will remain on the surface of the anhydrous sodium sulfate particles, thereby reducing the yield of the patchouli volatile oil.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a method for preparing patchouli oil volatile oil, the method for preparing patchouli oil volatile oil is realized by patchouli oil volatile oil preparation equipment, the patchouli oil volatile oil preparation equipment comprises a frame, a patchouli volatile oil containing mechanism is arranged in the middle of the inner side of the frame, a driving mechanism is arranged at the top of the inner side of the frame, an anhydrous sodium sulfate supply mechanism is arranged at the bottom of the driving mechanism, a longitudinal distribution mechanism is arranged on the inner side of the patchouli volatile oil containing mechanism and the anhydrous sodium sulfate supply mechanism, and a blocking mechanism is arranged at the top of the longitudinal distribution mechanism; The driving mechanism drives the anhydrous sodium sulfate supply mechanism to move downward, so that the anhydrous sodium sulfate particles in the anhydrous sodium sulfate supply mechanism enter the longitudinal distribution mechanism.

The driving mechanism drives the blocking mechanism, so that the blocking mechanism blocks the longitudinal distribution mechanism. In the subsequent upward resetting process of the driving mechanism, the longitudinal distribution mechanism is driven by the anhydrous sodium sulfate supply mechanism to rotate and rise synchronously, so that the residual patchouli volatile oil is thrown out, and the used anhydrous sodium sulfate particles are output at the same time.

[0011] Preferably, the longitudinal distribution mechanism comprises a rotating shaft, a second magnet, an end plate, a containing frame, a discharge channel, a mesh plate, a discharge pipe and a discharge channel; The rotating shaft slides through the containing kettle, the second magnet is fixedly arranged at the top end of the rotating shaft, the end plate is rotatably arranged at the bottom end of the rotating shaft through a bearing, the containing frame is fixedly arranged on the side of the rotating shaft and is slidably arranged inside the containing kettle, the discharge channel is opened at the bottom outside the containing frame, two mesh plates are provided, and the two mesh plates are respectively fixedly arranged on both sides of the containing frame, the discharge pipe is fixedly provided on the inner side of the top of the containing frame and slides through the rotating disk, and two discharge channels are provided, and the two discharge channels are respectively opened at the bottom of the front side and the bottom of the back side of the discharge pipe.

[0012] Preferably, the blocking mechanism comprises a blocking column, a second spring, a blocking plate, a third magnet, an outer sleeve and a fourth magnet; The blocking column is slidably set on the inner side of the discharge pipe, the second spring is sleeved on the outer side of the blocking column and fixedly connected between the top of the discharge pipe and the bottom of the blocking plate, the blocking plate is fixedly set on the top of the blocking column, the third magnet is located on the outer side of the second spring and fixedly set on the bottom of the blocking plate, the outer sleeve is located on the outer side of the second spring and fixedly set on the top of the discharge pipe, and the fourth magnet is fixedly set on the top of the outer sleeve.

[0013] Preferably, the method specifically comprises the following steps: S1, taking patchouli medicinal material, grinding it and sieving it, adding hemicellulase and distilled water to mix it and adding it to a buffer solution for enzymolysis, and after the enzymolysis is completed, using a distillation method to obtain a hydrous patchouli volatile oil; S2, adding the patchouli volatile oil containing water into the containing kettle through the patchouli volatile oil inlet pipe, starting the driving motor, and driving the reciprocating screw to rotate after the driving motor is started. When the reciprocating screw rotates, the outer sleeve guided by the guide plate and the guide rod is driven to descend. When the outer sleeve descends, the inner sleeve is driven to descend through the first spring, and the pressing plate is driven to descend through the guide plate. When the inner sleeve descends, the anhydrous sodium sulfate supply mechanism is driven to descend as a whole. In this process, the reciprocating screw drives the square shaft to rotate through the square groove, and when the square shaft rotates, the limit frame is driven to rotate, and the longitudinal distribution mechanism and the blocking mechanism are driven to rotate at the same time; S3, when the outer sleeve descends to a first threshold, the movable ring fits on the top of the holding kettle, and the first magnet is adsorbed on the top of the second magnet. At this time, the feeding channel enters the inner side of the limit frame, and the anhydrous sodium sulfate particles on the inner side of the limit frame enter the inside of the feeding pipe through the feeding channel, and then enter the inside of the holding frame under the action of gravity. Since the opening of the discharge channel is blocked by the holding kettle, the anhydrous sodium sulfate particles cannot be discharged through the discharge channel. At this time, as the longitudinal distribution mechanism continues to rotate, the longitudinal distribution mechanism drives the sewage sodium sulfate particles to continue to rotate in the aqueous patchouli volatile oil inside the holding kettle, thereby dehydrating the aqueous patchouli volatile oil. At the same time, due to the obstruction of the holding kettle, the anhydrous sodium sulfate supply mechanism cannot continue to descend, that is, the inner sleeve cannot continue to descend. Subsequently, as the outer sleeve continues to descend, the first spring is continuously compressed; S4, when the outer sleeve descends to a second threshold, the bottom of the pressing plate contacts the top of the blocking plate, and as the pressing plate continues to descend, the blocking plate drives the blocking column to descend synchronously, driving the third magnet to approach the fourth magnet, and compressing the second spring at the same time; S5, when the outer sleeve descends to a third threshold, the third magnet and the fourth magnet attract each other, the blocking column blocks the material discharge channel, and the outer sleeve reaches the bottom of the reciprocating thread on the outer side of the reciprocating screw. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves upward and resets, and the compressed first spring is gradually reset during the upward movement of the outer sleeve; S6, when the upward movement distance of the outer sleeve reaches the fourth threshold, the compressed first spring is reset, and the dehydration of the hydrous patchouli volatile oil is completed. At this time, the dehydrated patchouli volatile oil in the receiving kettle is output through the patchouli volatile oil output pipe. Subsequently, as the outer sleeve continues to rise, the outer sleeve drives the rotating disk to rise through the first spring and the inner sleeve. When the rotating disk rises, the rotating shaft is driven to rise through the first magnet and the second magnet. When the rotating shaft rises, the receiving frame is driven to rise, so that the receiving frame is gradually moved out of the patchouli volatile oil. At this time, due to the continuous rotation of the longitudinal distribution mechanism, the patchouli volatile oil remaining on the surface of the anhydrous sodium sulfate particles in the receiving frame is thrown out under the action of centrifugal force; S7, when the upward movement distance of the outer sleeve reaches the fifth threshold, the inner wall of the holding kettle releases the blockage of the discharge channel. At this time, as the holding frame continues to rotate, the used anhydrous sodium sulfate particles are thrown out through the discharge channel. At the same time, due to the obstruction of the guide shell, they finally fall into the inner side of the guide shell and are then discharged through the outlet groove; S8, when the upward movement distance of the outer sleeve reaches the sixth threshold, the top of the end plate fits with the bottom of the container. At this time, due to the obstruction of the end plate, the second magnet can no longer drive the rotating shaft to rise. Subsequently, as the outer sleeve continues to move upward, the first magnet and the second magnet separate from each other. At this time, the longitudinal distribution mechanism is reset under the action of gravity. During the resetting process of the longitudinal distribution mechanism, the blocking mechanism is driven to descend synchronously. During the descent of the blocking mechanism, the limit frame pushes the blocking plate to move up and reset, and the third magnet and the fourth magnet separate from each other. S9, when the upward movement distance of the outer sleeve reaches the seventh threshold, the outer sleeve arrives at the initial position, that is, the top of the reciprocating thread on the outer side of the reciprocating screw, and the drive motor is stopped at this time.

[0014] Technical effects and advantages of the present invention: The present invention is provided with a patchouli volatile oil containing mechanism, a driving mechanism, an anhydrous sodium sulfate supply mechanism, a longitudinal distribution mechanism and a blocking mechanism, so that the driving mechanism is used to drive the anhydrous sodium sulfate supply mechanism to move downward, so that the anhydrous sodium sulfate particles in the anhydrous sodium sulfate supply mechanism enter into the longitudinal distribution mechanism, and at the same time, the anhydrous sodium sulfate supply mechanism drives the longitudinal distribution mechanism to rotate, so that the longitudinal distribution mechanism drives the anhydrous sodium sulfate particles in it to dehydrate the patchouli volatile oil in the patchouli volatile oil containing mechanism, and then the driving mechanism drives the blocking mechanism, so that the blocking mechanism blocks the longitudinal distribution mechanism, so that the anhydrous sodium sulfate particles are prevented from entering into the longitudinal distribution mechanism when the longitudinal distribution mechanism is reset, and in the subsequent upward reset process of the driving mechanism, the longitudinal distribution mechanism is in the anhydrous sodium sulfate supply mechanism. The sodium sulfate supply mechanism rotates and rises synchronously, thereby throwing out the residual patchouli volatile oil and outputting the used anhydrous sodium sulfate particles. The blocking mechanism is pushed by the patchouli volatile oil containing mechanism during the resetting process of the longitudinal distribution mechanism, thereby resetting synchronously. Compared with the same type of device in the prior art, the present invention can automatically and quantitatively add the anhydrous sodium sulfate particles to avoid the waste of anhydrous sodium sulfate. After the dehydration is completed, the patchouli volatile oil remaining on the surface of the anhydrous sodium sulfate particles can be recovered and the used anhydrous sodium sulfate particles can be automatically output, thereby ensuring the yield of the patchouli volatile oil without manually cleaning the anhydrous sodium sulfate particles. In addition, the anhydrous sodium sulfate particles can be vertically arranged in the water-containing patchouli volatile oil and rotate continuously, thereby ensuring the dehydration effect.

[0023] Example 1

[0024] The present invention provides Figure 1-Figure 6 A method for preparing patchouli oil volatile oil is shown, the method for preparing patchouli oil volatile oil is implemented by patchouli oil volatile oil preparation equipment, the patchouli oil volatile oil preparation equipment comprises a frame 1, a patchouli volatile oil containing mechanism 2 is arranged in the middle of the inner side of the frame 1, a driving mechanism 3 is arranged at the top of the inner side of the frame 1, an anhydrous sodium sulfate supply mechanism 4 is arranged at the bottom of the driving mechanism 3, a longitudinal distribution mechanism 5 is arranged on the inner side of the patchouli volatile oil containing mechanism 2 and the anhydrous sodium sulfate supply mechanism 4, and a blocking mechanism 6 is arranged at the top of the longitudinal distribution mechanism 5; The driving mechanism 3 drives the anhydrous sodium sulfate supply mechanism 4 to move downward, so that the anhydrous sodium sulfate particles in the anhydrous sodium sulfate supply mechanism 4 enter the longitudinal distribution mechanism 5. At the same time, the anhydrous sodium sulfate supply mechanism 4 drives the longitudinal distribution mechanism 5 to rotate, so that the longitudinal distribution mechanism 5 drives the anhydrous sodium sulfate particles in it to dehydrate the patchouli volatile oil in the patchouli volatile oil containing mechanism 2. The driving mechanism 3 drives the blocking mechanism 6, so that the blocking mechanism 6 blocks the longitudinal distribution mechanism 5. In the subsequent upward resetting process of the driving mechanism 3, the longitudinal distribution mechanism 5 is driven by the anhydrous sodium sulfate supply mechanism 4 to rotate and rise synchronously, so as to throw out the residual patchouli volatile oil and output the used anhydrous sodium sulfate particles.

[0025] like Figure 3 As shown, the patchouli volatile oil containing mechanism 2 comprises a guide shell 21, a guide groove 22, a containing kettle 23, a patchouli volatile oil input pipe 24 and a patchouli volatile oil output pipe 25, wherein the guide shell 21 is fixedly arranged at the middle of the inner side of the frame 1, the guide groove 22 is opened at the right bottom of the guide shell 21, the containing kettle 23 is fixedly arranged at the inner side of the guide shell 21, the patchouli volatile oil input pipe 24 is fixedly penetrated at the left top of the containing kettle 23, and the patchouli volatile oil output pipe 25 is fixedly penetrated at the left bottom of the containing kettle 23.

[0026] By setting the above structure, it is convenient to add the aqueous patchouli volatile oil into the containing kettle 23 through the patchouli volatile oil inlet pipe 24. When the anhydrous sodium sulfate particles after subsequent use are thrown out, they are blocked by the guide shell 21 and finally fall into the inner side of the guide shell 21, and then are output through the outlet groove 22.

[0027] like Figure 4 As shown, the driving mechanism 3 includes a reciprocating screw 31, a driving motor 32, a square slot 33, an outer sleeve 34, a first spring 35, an inner sleeve 36, a guide plate 37, a guide rod 38 and a pressing plate 39, wherein the reciprocating screw 31 passes through the frame 1 and is rotatably connected to the frame 1 through a bearing, the driving motor 32 is fixedly arranged on the top of the frame 1 and is transmission-connected to the reciprocating screw 31, the square slot 33 is opened at the bottom end of the reciprocating screw 31, and the outer sleeve 34, the first spring 35 and the inner sleeve 36 are arranged in order from top to bottom. The outer sleeve 34 is transmission-connected to the reciprocating screw 31, the first spring 35 is fixedly connected between the outer sleeve 34 and the inner sleeve 36, the inner sleeve 36 is slidingly connected to the reciprocating screw 31 and is slidably nested in the inner side of the outer sleeve 34 along the vertical direction, the guide plate 37 is fixedly sleeved on the top of the outer side of the outer sleeve 34, the guide rod 38 slides through the frame 1 and is fixedly connected to the guide plate 37, and the pressing plate 39 is rotatably nested at the bottom of the guide plate 37 through a bearing.

[0028] By setting the above structure, the reciprocating screw 31 can be driven to rotate after the driving motor 32 is started. When the reciprocating screw 31 rotates, the outer sleeve 34 guided by the guide plate 37 and the guide rod 38 is driven to descend. When the outer sleeve 34 descends, the inner sleeve 36 is driven to descend through the first spring 35, and the pressing plate 39 is driven to descend through the guide plate 37. When the inner sleeve 36 descends, the anhydrous sodium sulfate supply mechanism 4 is driven to descend as a whole.

[0029] like Figure 5 As shown, the anhydrous sodium sulfate supply mechanism 4 includes a rotating disk 41, a square shaft 42, a first magnet 43, a movable ring 44 and a limit frame 45, wherein the rotating disk 41 is rotatably arranged at the bottom end of the inner sleeve 36 through a bearing, the square shaft 42 is fixedly arranged at the top center of the rotating disk 41 and slidably arranged on the inner side of the square groove 33, the first magnet 43 is fixedly arranged at the bottom center of the rotating disk 41, the movable ring 44 is rotatably sleeved on the outer side of the rotating disk 41 through a bearing, and the limit frame 45 is fixedly arranged on the top right side of the rotating disk 41 and its inner side is filled with anhydrous sodium sulfate particles.

[0030] By setting the above structure, the square shaft 42 can be driven to rotate through the square groove 33 during the rotation of the reciprocating screw 31. When the square shaft 42 rotates, it drives the limit frame 45 to rotate, and at the same time drives the longitudinal distribution mechanism 5 and the blocking mechanism 6 to rotate.

[0031] like Figure 6 As shown, the longitudinal distribution mechanism 5 includes a rotating shaft 51, a second magnet 52, an end plate 53, a containing frame 54, a discharge channel 55, a mesh plate 56, a discharge pipe 57 and a discharge channel 58, wherein the rotating shaft 51 slides through the containing kettle 23, the second magnet 52 is fixedly arranged at the top of the rotating shaft 51, the end plate 53 is rotatably arranged at the bottom of the rotating shaft 51 through a bearing, the containing frame 54 is fixedly arranged on the side of the rotating shaft 51 and is slidably arranged inside the containing kettle 23, the discharge channel 55 is opened at the outer bottom of the containing frame 54, two mesh plates 56 are provided, and the two mesh plates 56 are respectively fixedly arranged on both sides of the containing frame 54, the discharge pipe 57 is fixedly arranged on the inner side of the top of the containing frame 54 and slides through the rotating disk 41, and two discharge channels 58 are provided, and the two discharge channels 58 are respectively opened at the front bottom and the back bottom of the discharge pipe 57.

[0032] By setting the above structure, after the feed channel 58 enters the inner side of the limit frame 45, the anhydrous sodium sulfate particles inside the limit frame 45 enter the feed pipe 57 through the feed channel 58, and then enter the inside of the containing frame 54 under the action of gravity. Since the opening of the discharge channel 55 is blocked by the containing kettle 23, the anhydrous sodium sulfate particles cannot be discharged through the discharge channel 55. At this time, as the longitudinal distribution mechanism 5 continues to rotate, the longitudinal distribution mechanism 5 drives the sewage sodium sulfate particles to continuously rotate in the aqueous patchouli volatile oil inside the containing kettle 23, thereby dehydrating the aqueous patchouli volatile oil.

[0033] like Figure 6 As shown, the blocking mechanism 6 includes a blocking column 61, a second spring 62, a blocking plate 63, a third magnet 64, an outer sleeve 65 and a fourth magnet 66, wherein the blocking column 61 is slidably arranged on the inner side of the discharge tube 57, the second spring 62 is sleeved on the outer side of the blocking column 61 and fixedly connected between the top of the discharge tube 57 and the bottom of the blocking plate 63, the blocking plate 63 is fixedly arranged at the top of the blocking column 61, the third magnet 64 is located on the outer side of the second spring 62 and fixedly arranged at the bottom of the blocking plate 63, the outer sleeve 65 is located on the outer side of the second spring 62 and fixedly arranged at the top of the discharge tube 57, and the fourth magnet 66 is fixedly arranged at the top of the outer sleeve 65.

[0034] By setting the above structure, the bottom of the pressing plate 39 is in contact with the top of the blocking plate 63. As the pressing plate 39 continues to descend, the blocking plate 63 drives the blocking column 61 to descend synchronously, driving the third magnet 64 to approach the fourth magnet 66, and compressing the second spring 62 until the third magnet 64 and the fourth magnet 66 are attracted to each other, and the blocking column 61 blocks the feeding channel 58, thereby preventing anhydrous sodium sulfate particles from entering the interior of the longitudinal distribution mechanism 5 during the subsequent resetting process of the longitudinal distribution mechanism 5. In addition, the blocking mechanism 6 will be driven to descend synchronously during the resetting process of the longitudinal distribution mechanism 5. During the descent of the blocking mechanism 6, the limit frame 45 pushes the blocking plate 63 to move up and reset, and the third magnet 64 and the fourth magnet 66 are separated from each other.

[0035] Example 2

[0036] The method specifically comprises the following steps: S1, taking patchouli medicinal material, grinding it and sieving it, adding hemicellulase and distilled water to mix it and adding it to a buffer solution for enzymolysis, and after the enzymolysis is completed, using a distillation method to obtain a hydrous patchouli volatile oil; S2, adding the patchouli volatile oil containing water into the containing kettle 23 through the patchouli volatile oil input pipe 24, starting the driving motor 32, and driving the reciprocating screw 31 to rotate after the driving motor 32 is started. When the reciprocating screw 31 rotates, it drives the outer sleeve 34 guided by the guide plate 37 and the guide rod 38 to descend. When the outer sleeve 34 descends, it drives the inner sleeve 36 to descend through the first spring 35, and drives the pressing plate 39 to descend through the guide plate 37. When the inner sleeve 36 descends, it drives the anhydrous sodium sulfate supply mechanism 4 to descend as a whole. In this process, the reciprocating screw 31 drives the square shaft 42 to rotate through the square groove 33. When the square shaft 42 rotates, it drives the limit frame 45 to rotate, and at the same time drives the longitudinal distribution mechanism 5 and the blocking mechanism 6 to rotate; S3, when the outer sleeve 34 descends to a first threshold, the movable ring 44 is attached to the top of the holding kettle 23, and the first magnet 43 is adsorbed on the top of the second magnet 52. At this time, the feeding channel 58 enters the inner side of the limit frame 45, and the anhydrous sodium sulfate particles on the inner side of the limit frame 45 enter the inside of the feeding pipe 57 through the feeding channel 58, and then enter the inside of the holding frame 54 under the action of gravity. Since the opening of the discharge channel 55 is blocked by the holding kettle 23, the anhydrous sodium sulfate particles cannot be discharged through the discharge channel 55. At this time, as the longitudinal distribution mechanism 5 continues to rotate, the longitudinal distribution mechanism 5 drives the sewage sodium sulfate particles to continue to rotate in the aqueous patchouli volatile oil inside the holding kettle 23, thereby dehydrating the aqueous patchouli volatile oil. At the same time, due to the obstruction of the holding kettle 23, the anhydrous sodium sulfate supply mechanism 4 cannot continue to descend, that is, the inner sleeve 36 cannot continue to descend. Subsequently, as the outer sleeve 34 continues to descend, the first spring 35 is continuously compressed; S4, when the outer sleeve 34 descends to a second threshold, the bottom of the pressing plate 39 contacts the top of the blocking plate 63. As the pressing plate 39 continues to descend, the blocking plate 63 drives the blocking column 61 to descend synchronously, driving the third magnet 64 to approach the fourth magnet 66, and compressing the second spring 62 at the same time; S5, when the outer sleeve 34 descends to a third threshold, the third magnet 64 and the fourth magnet 66 are attracted to each other, the blocking column 61 blocks the material discharge channel 58, and the outer sleeve 34 reaches the bottom of the reciprocating thread on the outer side of the reciprocating screw 31. Subsequently, as the reciprocating screw 31 continues to rotate, the outer sleeve 34 moves upward and resets, and the compressed first spring 35 is gradually reset during the upward movement of the outer sleeve 34; S6, when the upward movement distance of the outer sleeve 34 reaches the fourth threshold, the compressed first spring 35 is reset, and the dehydration of the hydrous patchouli volatile oil is completed. At this time, the patchouli volatile oil dehydrated in the receiving kettle 23 is output through the patchouli volatile oil output pipe 25. Subsequently, as the outer sleeve 34 continues to rise, the outer sleeve 34 drives the rotating disk 41 to rise through the first spring 35 and the inner sleeve 36. When the rotating disk 41 rises, the rotating shaft 51 is driven to rise through the first magnet 43 and the second magnet 52. When the rotating shaft 51 rises, it drives the receiving frame 54 to rise, so that the receiving frame 54 is gradually moved out of the patchouli volatile oil. At this time, due to the continuous rotation of the longitudinal distribution mechanism 5, the patchouli volatile oil remaining on the surface of the anhydrous sodium sulfate particles in the receiving frame 54 is thrown out under the action of centrifugal force; S7, when the upward movement distance of the outer sleeve 34 reaches the fifth threshold, the inner wall of the containing kettle 23 releases the blockage of the discharge channel 55. At this time, as the containing frame 54 continues to rotate, the used anhydrous sodium sulfate particles are thrown out through the discharge channel 55, and at the same time, due to the obstruction of the guide shell 21, they finally fall into the inner side of the guide shell 21 and are then discharged through the outlet groove 22; S8, when the upward movement distance of the outer sleeve 34 reaches the sixth threshold, the top of the end plate 53 is in contact with the bottom of the container 23. At this time, due to the obstruction of the end plate 53, the second magnet 52 can no longer drive the rotating shaft 51 to rise. Subsequently, as the outer sleeve 34 continues to move upward, the first magnet 43 and the second magnet 52 separate from each other. At this time, the longitudinal distribution mechanism 5 is reset under the action of gravity. During the resetting process of the longitudinal distribution mechanism 5, the blocking mechanism 6 is driven to descend synchronously. During the descent of the blocking mechanism 6, the limit frame 45 pushes the blocking plate 63 to move upward and reset, and the third magnet 64 and the fourth magnet 66 separate from each other. S9, when the upward movement distance of the outer sleeve 34 reaches the seventh threshold, the outer sleeve 34 arrives at the initial position, that is, the top of the reciprocating thread on the outer side of the reciprocating screw 31, and the driving motor 32 is stopped at this time.

At the same time, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold and the seventh threshold are recorded for the convenience of accurately describing the actual working conditions of the scheme; When the solution of the present application is actually produced, according to the actual specifications of the reciprocating screw 31, the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value, the sixth threshold value and the seventh threshold value are all specific values.

The method for preparing a volatile oil of patchouli oil according to claim 6, characterized in that: The method specifically comprises the following steps: S1, taking patchouli medicinal material, grinding it and sieving it, adding hemicellulase and distilled water to mix it and adding it to a buffer solution for enzymolysis, and after the enzymolysis is completed, using a distillation method to obtain a hydrous patchouli volatile oil; S2, adding the patchouli volatile oil containing water into the containing kettle (23) through the patchouli volatile oil inlet pipe (24), starting the driving motor (32), and driving the reciprocating screw (31) to rotate after starting. When the reciprocating screw (31) rotates, it drives the outer sleeve (34) guided by the guide plate (37) and the guide rod (38) to descend. When the outer sleeve (34) descends, it drives the inner sleeve (36) to descend through the first spring (35), and drives the pressing plate (39) to descend through the guide plate (37). When the inner sleeve (36) descends, it drives the anhydrous sodium sulfate supply mechanism (4) to descend as a whole. In this process, the reciprocating screw (31) drives the square shaft (42) to rotate through the square groove (33). When the square shaft (42) rotates, it drives the limit frame (45) to rotate, and at the same time drives the longitudinal distribution mechanism (5) and the blocking mechanism (6) to rotate; S3, when the outer sleeve (34) descends a distance that reaches a first threshold, the movable ring (44) fits against the top of the containing kettle (23), and the first magnet (43) is adsorbed on the top of the second magnet (52). At this time, the discharge channel (58) enters the inner side of the limit frame (45), and the anhydrous sodium sulfate particles inside the limit frame (45) enter the discharge pipe (57) through the discharge channel (58), and then enter the inside of the containing frame (54) under the action of gravity. Since the opening of the discharge channel (55) is blocked by the containing kettle (23), the anhydrous sodium sulfate particles The sodium particles cannot be discharged through the discharge channel (55). At this time, as the longitudinal distribution mechanism (5) continues to rotate, the longitudinal distribution mechanism (5) drives the sewage sodium sulfate particles to continuously rotate in the aqueous patchouli volatile oil inside the receiving kettle (23), thereby dehydrating the aqueous patchouli volatile oil. At the same time, due to the obstruction of the receiving kettle (23), the anhydrous sodium sulfate supply mechanism (4) cannot continue to descend, that is, the inner sleeve (36) cannot continue to descend. Subsequently, as the outer sleeve (34) continues to descend, the first spring (35) is continuously compressed; S4, when the outer sleeve (34) descends a distance reaching a second threshold, the bottom of the pressing plate (39) contacts the top of the blocking plate (63), and as the pressing plate (39) continues to descend, the blocking plate (63) drives the blocking column (61) to descend synchronously, driving the third magnet (64) to approach the fourth magnet (66), and compressing the second spring (62) at the same time; S5, when the outer sleeve (34) descends to a third threshold, the third magnet (64) and the fourth magnet (66) attract each other, the blocking column (61) blocks the material discharge channel (58), and the outer sleeve (34) reaches the bottom of the reciprocating thread on the outside of the reciprocating screw (31). Subsequently, as the reciprocating screw (31) continues to rotate, the outer sleeve (34) moves upward and resets, and the compressed first spring (35) is gradually reset during the upward movement of the outer sleeve (34); S6, when the upward movement distance of the outer sleeve (34) reaches the fourth threshold value, the compressed first spring (35) is reset, and the dehydration of the hydrous patchouli volatile oil is completed. At this time, the dehydrated patchouli volatile oil in the containing kettle (23) is output through the patchouli volatile oil output pipe (25). Subsequently, as the outer sleeve (34) continues to rise, the outer sleeve (34) drives the rotating disk (41) to rise through the first spring (35) and the inner sleeve (36). When the rotating disk (41) rises, the rotating shaft (51) is driven to rise through the first magnet (43) and the second magnet (52). When the rotating shaft (51) rises, it drives the containing frame (54) to rise, thereby causing the containing frame (54) to gradually move out of the patchouli volatile oil. At this time, due to the continuous rotation of the longitudinal distribution mechanism (5), the patchouli volatile oil remaining on the surface of the anhydrous sodium sulfate particles in the containing frame (54) is thrown out under the action of centrifugal force; S7, when the upward movement distance of the outer sleeve (34) reaches a fifth threshold value, the inner wall of the containing kettle (23) releases the blockage of the discharge channel (55), and as the containing frame (54) continues to rotate, the used anhydrous sodium sulfate particles are thrown out through the discharge channel (55), and at the same time, due to the obstruction of the guide housing (21), they finally fall into the inner side of the guide housing (21) and are then discharged through the outlet groove (22); S8, when the upward movement distance of the outer sleeve (34) reaches the sixth threshold value, the top of the end plate (53) fits with the bottom of the container (23), and at this time, due to the obstruction of the end plate (53), the second magnet (52) can no longer drive the rotating shaft (51) to rise, and subsequently, as the outer sleeve (34) continues to move upward, the first magnet (43) and the second magnet (52) separate from each other, and at this time, the longitudinal distribution mechanism (5) is reset under the action of gravity, and the longitudinal distribution mechanism (5) drives the blocking mechanism (6) to descend synchronously during the resetting process, and the blocking mechanism (6) is descending during the descent process, The limit frame (45) pushes the blocking plate (63) to move upward and reset, and the third magnet (64) and the fourth magnet (66) separate from each other; S9, when the upward movement distance of the outer sleeve (34) reaches the seventh threshold value, the outer sleeve (34) reaches the initial position, that is, the topmost point of the reciprocating thread on the outer side of the reciprocating screw (31), and the driving motor (32) is stopped at this time.
