Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of distillation device, and particularly relates to a water vapor distillation device for extracting natural product volatile oil. BACKGROUND

[0002] The distillation device is a device for separating components in a mixed liquid or liquid-solid system by evaporation of low-boiling-point components and condensation, and is often used in the extraction of natural product volatile oil. In addition to flower and grass essential oil, Chinese herbal medicine volatile oil, also known as Chinese herbal medicine essential oil, has attracted people's attention. Ginger essential oil is favored by people due to its strong efficacy. In the production of ginger essential oil, a distillation device is often used to heat and distill ginger. However, the contact area between ginger and steam is low, which easily affects the distillation efficiency.

[0003] In the prior art, a sliding rod is used to drive a sliding plate to slide, and the sliding plate drives a cutting piece to cut ginger blocks in the placing groove. In this way, the ginger slices are not perforated, turned and extruded, which reduces the extraction efficiency and yield of ginger essential oil. A cutter is used to cut flowers and grasses, and the cut flowers and grasses can better contact with water, which is beneficial to distilling the essential oil in the flowers and grasses. Alternatively, a stirring blade is used to stir and turn the flowers and grasses. In the above two ways, the distillation materials are greatly damaged, and debris and impurities are easily generated, which reduces the quality and extraction efficiency of the distillation product.

[0018] Compared with the prior art, the water vapor distillation device for extracting natural product volatile oil has the following advantages:

[0019] 1. This invention incorporates a supporting mechanism and an auxiliary mechanism. The supporting mechanism supports and controls the vertical position of the perforated disc. When the auxiliary mechanism is working, it drives the perforating component and the turning component to rotate continuously. With the cooperation of the bevel gear and the end face gear ring, the rotating shaft in the perforating component and the arc plate in the turning component rotate around the motor output end while simultaneously rotating on their own axes. The rotating shaft, through a fixed pin on it, perforates the upper layer of ginger slices on the perforated disc, increasing the surface area and porosity of the ginger slices, making it easier for water vapor to penetrate the interior of the ginger slices, accelerating the distillation process, and improving the extraction efficiency of essential oils. During the movement of the arc plate, it simultaneously scoops up and turns the ginger slices on the perforated disc, improving the distillation and perforation effect of the ginger slices, while the hemispherical extrusion block and the protrusions on the perforated disc extrude the ginger slices between them, further damaging the ginger slice cells, allowing more essential oil components to be squeezed out, thus improving the extraction efficiency and yield of essential oils.

[0020] 2. This invention, through the arrangement of a supporting mechanism and an auxiliary mechanism, works in conjunction to control the height and position of the perforated disc and the arc-shaped plate. During movement, it performs deep turning, shallow turning, and squeezing operations on the ginger slices. The deep turning operation scoops up and turns the ginger slices on the perforated disc, distributing them more evenly and preventing clumping and sticking. It also adjusts the position of the ginger slices, facilitating more even perforation by the perforating component. The shallow turning operation only scoops up and turns the upper layer of ginger slices, allowing the lower layer to absorb and transfer heat more easily. This avoids excessively frequent and rapid turning, which could interrupt the heat transfer process and improve the efficiency of heat transfer. The uniform heating of the ginger slices in each layer ensures that the lower layer is continuously heated, promoting the extraction of essential oils. The squeezing operation, with its reciprocating up-and-down motion of the curved plate, further exacerbates the extraction of essential oils. Through cyclical deep turning, shallow turning, and squeezing, the ginger slices on the perforated disc are perforated, turned, and squeezed. This method is gentler than traditional stirring methods, causing less damage to the ginger slices. It ensures sufficient contact between the ginger slices and steam while minimizing damage and impurities, thus improving the extraction efficiency and quality of essential oils.

[0033] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0034] Reference Figure 1 and Figure 2A steam distillation apparatus for extracting volatile oils from natural products includes a mounting frame 1, a heating tank 5 fixedly connected to the mounting frame 1, a condenser collection assembly connected to the top of the heating tank 5, a side door 6 installed on the side, and further includes:

[0035] The condensation collection assembly includes a chiller 2, a water storage container 3, and a separating funnel 4, which are fixedly connected to the mounting frame 1. The output end of the chiller 2 is connected to the bottom of the water storage container 3, and the input end is connected to the top of the water storage container 3. It is used to circulate cold water into the water storage container 3. The top of the heating tank 5 is connected to a condenser tube. The end of the condenser tube away from the heating tank 5 passes through the water storage container 3 in a sealed manner and is connected to the top of the separating funnel 4. The part of the condenser tube inside the water storage container 3 is spiral-shaped.

[0036] Heating tank 5 is heated and replenished with pure water by an external device to carry out heating distillation operation. The refrigerator 2 adopts existing technology. During the distillation process, the mixed vapor generated inside heating tank 5 enters the interior of separatory funnel 4 through condenser tube. The middle part of condenser tube passes through the interior of water storage container 3. The refrigerator 2 continuously circulates cold water into the interior of water storage container 3. The cold water cools condenser tube, liquefies the mixed vapor, and collects it through separatory funnel 4.

[0037] Reference Figure 3 , Figure 6 and Figure 7 The support mechanism includes multiple support components connected to the inner wall of the heating tank 5, and the same perforated disk 7 is placed on the output end of the multiple support components.

[0038] The supporting component includes a mounting housing 14 fixedly connected to the inner wall of the heating tank 5. A first electric telescopic rod 21 is installed at the bottom of the mounting housing 14. An L-shaped fixing plate 22 is fixedly connected to the output end of the first electric telescopic rod 21. A sliding arc plate 23 is slidably connected to the L-shaped fixing plate 22. A plurality of springs 25 are fixedly connected between the L-shaped fixing plate 22 and the sliding arc plate 23. A support block 24 is fixedly connected to the side of the sliding arc plate 23 away from the springs 25. The end of the support block 24 away from the sliding arc plate 23 passes through the mounting housing 14 and abuts against the bottom of the perforated plate 7. A through groove is provided on the mounting housing 14 for the support block 24 to move.

[0039] Reference Figures 3-5 and Figures 8-11The auxiliary mechanism includes a rotating assembly connected to the heating tank 5. The output end of the rotating assembly is sealed and extends into the interior of the heating tank 5, and is connected to a mounting block 16 and a mounting plate. A punching assembly is connected to the mounting block 16. A second bevel gear 36 is connected to the end of the punching assembly away from the mounting block 16. The second bevel gear 36 meshes with an end face gear ring 12. The end face gear ring 12 is fixedly connected to the inner wall of the heating tank 5. A flipping assembly is connected to the mounting plate. The flipping assembly includes a flipping part that can be raised, lowered, and rotated. A first bevel gear 31 is connected to the end of the flipping part away from the mounting plate. The first bevel gear 31 meshes with the end face gear ring 12. The punching assembly and the flipping part are both located above the perforated disk 7.

[0040] The rotating assembly includes a motor 8 installed at the bottom of the heating tank 5. The output end of the motor 8 is coaxially fixedly connected to a connecting shaft 9. The end of the connecting shaft 9 away from the motor 8 is sealed through the bottom wall of the heating tank 5 and fixedly connected to a connecting block. The top of the connecting block is threadedly connected to a threaded tube 10. The mounting block 16 and the mounting plate are both fixedly connected to the outside of the threaded tube 10 and are distributed on both sides of the threaded tube 10.

[0041] The connecting block is in the shape of an inverted T. When the threaded tube 10 is threaded onto the connecting block, the threaded tube 10 rotates and comes into contact with the bottom of the connecting block to complete the fixation of the two. When the connecting shaft 9 rotates, causing the threaded tube 10 to continue to be locked, the connecting shaft 9 drives the threaded tube 10 to rotate through the connecting block.

[0042] The perforated disk 7 includes multiple components, and the supporting mechanism, connecting block, and structure connected to the connecting block also include multiple components, each corresponding to one of the multiple perforated disks 7.

[0043] The punching assembly includes a rotating shaft 17 rotatably connected to the mounting block 16, and a plurality of fixing pins 18 are fixedly connected to the outside of the rotating shaft 17.

[0044] Multiple fixing pins 18 are arranged in a circular array on the outside of the rotating shaft 17. Multiple actuating components are connected to the mounting block 16. Each actuating component corresponds to a row of fixing pins 18 along the axial direction of the rotating shaft 17. The actuating component includes a third electric telescopic rod 35 mounted on the mounting block 16. An L-shaped connecting plate 20 is fixedly connected to the output end of the third electric telescopic rod 35. A push plate 19 is fixedly connected to the L-shaped connecting plate 20. The push plate 19 slides through and engages with the multiple fixing pins 18 in the corresponding row.

[0045] A plurality of T-shaped rods 34 are fixedly connected to the side of the push plate 19 near the rotating shaft 17. The end of the T-shaped rod 34 away from the push plate 19 is slidably connected inside the rotating shaft 17.

[0046] The push plate 19 is slidably engaged with the rotating shaft 17 via the T-shaped rod 34, which can prevent the push plate 19 from separating from the fixing pin 18.

[0047] The flipping assembly includes a rotating connection part 26 rotatably connected to both ends of the flipping part. The rotating connection part 26 includes an electric push rod and a rotating ring fixedly connected to the output end of the electric push rod. The rotating ring is rotatably connected to the end of the flipping part. Of the two electric push rods, one is fixedly connected to the mounting plate, and the other is fixedly connected to a mounting plate 32. The end of the mounting plate 32 away from the electric push rod abuts against the top of the end face toothed ring 12.

[0048] The tumbling section is supported by the mounting plate 32, which prevents the tumbling section from being cantilevered and improves the stability of the tumbling section during movement.

[0049] The flipping part includes an arc-shaped plate 33 and connecting rods 29 fixedly connected to both ends of the arc-shaped plate 33. The connecting rods 29 are L-shaped. The ends of the two connecting rods 29 away from the arc-shaped plate 33 are coaxially arranged and coaxially rotate with the corresponding rotating ring. The arc-shaped plate 33 is arc-shaped, and its rotating front end is wedge-shaped. Multiple hemispherical extrusion blocks are fixedly connected to the back end. Multiple protrusions 15 are fixedly connected to the upper surface of the perforated disk 7. The multiple hemispherical extrusion blocks and the multiple protrusions 15 on the same radial direction on the perforated disk 7 are staggered.

[0050] Multiple protrusions 15 are arranged in a circular array on the porous disk 7, and their number is significantly smaller than the number of holes in the porous disk 7. Together with the hemispherical extrusion block, they form an auxiliary extrusion operation on the ginger slices.

[0051] A sliding housing 28 is slidably connected to the side of the threaded tube 10. An encoder is installed inside the sliding housing 28. A connecting rod 29 close to the threaded tube 10 is connected to the working end of the encoder. A limit block 30 is fixedly connected to this connecting rod 29. A limit hole is opened on the limit block 30. A second electric telescopic rod 27 is installed on the mounting plate. After the output end of the second electric telescopic rod 27 extends out, it engages with the limit hole.

[0052] The encoder uses existing technology to determine the angle of the connecting rod 29 connected to it, so as to facilitate the control of the angle of the arc plate 33 to cooperate with the squeezing operation of ginger slices.

[0053] The edge of the perforated disk 7 is fixedly connected to a blocking ring 11, and the top is coaxially rotatably connected to a shielding ring plate 13. The blocking ring 11 abuts against the inner wall of the heating tank 5, and the blocking ring 11 and the shielding ring plate 13 form an annular groove. The first bevel gear 31 and the second bevel gear 36 are both located inside the annular groove. The shielding ring plate 13 has a strip groove for the rotating shaft 17 and the connecting rod 29 to move.

[0054] The blocking ring 11 and the shielding ring plate 13 shield the first bevel gear 31 and the second bevel gear 36. When the rotating shaft 17 and the connecting rod 29 rotate axially around the threaded tube 10, they drive the shielding ring plate 13 to move accordingly, thus limiting the ginger slices on the perforated plate 7 and preventing the ginger slices from falling off the perforated plate 7.

[0055] The other end of the rotating shaft 17 away from the mounting block 16 rests on the blocking ring 11, effectively preventing the rotating shaft 17 from being cantilevered and improving its stability during movement.

[0056] When this invention is used, the heating tank 5 is connected to the separating funnel 4 through a condenser tube. During the distillation process, the mixed vapor generated in the heating tank 5 enters the interior of the separating funnel 4 through the condenser tube, which passes through the interior of the water storage container 3.

[0057] By continuously feeding cold water into the water storage container 3 through the refrigeration unit 2, the mixed vapor inside the condenser tube is liquefied and eventually enters the separatory funnel 4 for collection.

[0058] Before distillation begins, the motor 8 is fixedly mounted below the heating tank 5 by external support, and the connecting shaft 9 is sealed and rotatably connected to the lower end of the heating tank 5.

[0059] The support block 24 can be completely retracted into the mounting housing 14, which can prevent the support block 24 from blocking the installation operation of the perforated disk 7. Under the elastic force of the spring 25, the support block 24 extends out of the mounting housing 14, so that the support block 24 can support the perforated disk 7 and place the perforated disk 7 on the upper end of the three sets of support blocks 24.

[0060] Then, the threaded tube 10 is threadedly connected to the connecting block fixed on the outer surface of the connecting shaft 9. When the connecting shaft 9 rotates, the threaded tube 10 is locked until the threaded tube 10 and the connecting block are pressed together. At this time, the connecting shaft 9 rotates, and the threaded tube 10 is driven to rotate through the connecting block. At the same time, the first bevel gear 31 and the second bevel gear 36 are embedded in the annular groove between the blocking ring 11 and the shielding ring plate 13.

[0061] The strip groove on the shielding ring plate 13 is used for the installation of the rotating shaft 17 and the connecting rod 29. Then, the end face toothed ring 12 is fixedly set on the inner wall of the heating tank 5, so that the end face toothed ring 12 is above the first bevel gear 31 and the second bevel gear 36. Then, the mounting plate 32 is fixedly connected or threadedly connected to the upper end of the corresponding rotating connecting part 26, so that the mounting plate 32 contacts the upper end of the end face toothed ring 12. At this time, the end face toothed ring 12 can support the mounting plate 32 and maintain the stability of the movement of the arc plate 33.

[0062] After installing the three perforated discs 7 and their corresponding structures in sequence, place the ginger slices on the upper surface of the perforated discs 7 to complete the preparation work. In the subsequent distillation process, the loading and unloading of the ginger slices is completed by disassembling the side door 6 until the distillation is completed.

[0063] When distilling ginger slices, the ginger slices are evenly placed in multiple layers on the porous disk 7. The motor 8 works, and its output end drives the connecting shaft 9 to rotate, which in turn drives the mounting block 16 and the mounting plate to rotate through the connecting block and the threaded tube 10.

[0064] When the mounting block 16 rotates with the threaded tube 10, it drives the rotating shaft 17 to rotate around the threaded tube 10. At the same time, the second bevel gear 36 on the rotating shaft 17 meshes with the end face toothed ring 12, causing the rotating shaft 17 to rotate. This causes the fixing needle 18 to rotate and roll the upper layer of ginger slices on the perforated disc 7. When the fixing needle 18 rotates to the bottom of the rotating shaft 17, it penetrates the upper layer of ginger slices, increasing the surface area and porosity of the ginger slices. This makes it easier for water vapor to penetrate the interior of the ginger slices, which helps to accelerate the distillation process and improve the extraction efficiency of essential oils.

[0065] As the fixing pin 18 continues to rotate with the rotating shaft 17, the corresponding third electric telescopic rod 35 works, its output end extends, and drives the push plate 19 to move downward through the L-shaped connecting plate 20, separating the ginger slices that may be attached to the fixing pin 18 from the fixing pin 18, preventing the ginger slices from being attached to the fixing pin 18 and moving with it, thus ensuring the effectiveness of the fixing pin 18.

[0066] When the mounting plate rotates with the threaded tube 10, it drives the flipping part to rotate around the threaded tube 10. The first bevel gear 31 on the connecting rod 29 meshes with the end face toothed ring 12, causing the arc plate 33 and the two connecting rods 29 to rotate around themselves, making it convenient for the arc plate 33 to scoop up and flip the ginger slices.

[0067] During the distillation process, the first electric telescopic rod 21 operates, and its output end drives the L-shaped fixed plate 22 to move up and down. The L-shaped fixed plate 22 drives the support block 24 to move up and down through the sliding arc plate 23, thereby adjusting the height of the perforated plate 7.

[0068] The electric push rods in the two rotating connecting parts 26 are in operation. Their output ends drive the connecting rod 29 to move up and down through the rotating ring, thereby adjusting the height of the arc plate 33.

[0069] The distillation process includes deep turning, shallow turning, and extrusion operations.

[0070] Deep turning operation: Control the arc plate 33 to move upward to the upper limit position, so that the first bevel gear 31 meshes with the end face toothed ring 12. Control the perforated plate 7 to move upward to the upper limit position, so that when the arc plate 33 rotates, the wedge-shaped end of the arc plate 33 inserts between the ginger slice and the upper surface of the perforated plate 7, scooping up the ginger slice, and turning the scooped ginger slice over with the rotation of the arc plate 33 until the ginger slice between the two sets of protrusions 15 is turned over, so that the ginger slice on the perforated plate 7 is more evenly distributed, avoiding the ginger slice from clumping and sticking together. At the same time, it also changes the position of the ginger slice to a certain extent, making it easier for the piercing component to pierce the ginger slice more evenly.

[0071] When the arc plate 33 encounters the protrusion 15, the hemispherical extrusion block on the arc plate 33 rotates to face the protrusion 15. Multiple hemispherical extrusion blocks and multiple protrusions 15 move alternately, further extruding and destroying the cell structure of the ginger slice between them, thereby improving the extraction efficiency of essential oil.

[0072] Shallow turning operation: Since ginger slices need a certain amount of time to absorb and transfer heat during the heating process, if the turning is too frequent and rapid, it may interrupt this heat transfer process, resulting in uneven temperature distribution inside the ginger slices. Some areas may be overheated, while other areas may be underheated. Therefore, the arc plate 33 is controlled to be at the upper limit position, and the perforated plate 7 is controlled to move downward to the middle position. At this time, when the arc plate 33 rotates, the wedge-shaped end of the arc plate 33 can only turn the stacked upper layer of ginger slices, while the lower layer of ginger slices is less affected by the turning, and the continuous heating promotes the discharge of essential oils.

[0073] Squeezing operation: Control the arc plate 33 to move downward to the lower limit position, so that the first bevel gear 31 separates from the end face gear ring 12. Control the perforated disk 7 to continue to move downward to the lower limit position. At this time, when the arc plate 33 rotates, it does not contact the ginger slices on the perforated disk 7. The arc plate 33 is located at the angle detected by the encoder of the connecting rod 29. When the connecting rod 29 is placed vertically so that the outer side of the arc plate 33 faces downward, control the output end of the second electric telescopic rod 27 to extend and embed into the limit block 30, locking the connecting rod 29 and fixing the angle of the arc plate 33. During the process of the arc plate 33 rotating around the threaded tube 10, control the output end of the electric push rod to continuously extend and retract, so that the arc plate 33 moves up and down, thereby squeezing the ginger slices and further promoting the discharge of essential oil through squeezing.

[0074] Through cyclic deep turning, shallow turning, and squeezing operations, the ginger slices on the porous disc 7 are intermittently perforated, turned, and squeezed. Compared with the traditional stirring and turning method, this is gentler and causes less damage to the ginger slices. It ensures full contact between the ginger slices and steam, reduces damage to the ginger slices, improves the extraction efficiency and quality of essential oils, and reduces the occurrence of debris and impurities.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
