Description

Technical Field

[0001] The invention relates to the technical field of distillation devices, in particular to a steam distillation device for extracting volatile oil from natural products. Background Art

[0002] A distillation apparatus is a device that utilizes the different boiling points of components in a mixed liquid or liquid-solid system to evaporate the lower-boiling-point component and then condense it to separate the components. It is often used in the extraction of volatile oils from natural products. In addition to essential oils from flowers and herbs, volatile oils from traditional Chinese medicines, also known as TCM essential oils, have garnered significant attention. Among these TCM essential oils, ginger essential oil is particularly popular due to its potent properties. To produce ginger essential oil, a distillation apparatus is often used to heat and distill ginger. However, the low contact area between ginger and steam can affect distillation efficiency.

[0003] In the prior art, a slide bar is used to drive a slide plate to slide, and the slide plate drives a cutting blade to cut the ginger pieces inside the placement groove. In this method, there is a lack of piercing, turning and squeezing operations on the ginger slices, which reduces the extraction efficiency and yield of ginger essential oil. A cutter is used to chop the flowers and plants, and the chopped flowers and plants can have better contact with the water body, which is conducive to the distillation of the essence inside them. Alternatively, a stirring blade is used to stir and turn the flowers and plants. In the above two methods, the damage to the distillation material is greater, and debris and impurities are easily generated, which reduces the quality and extraction efficiency of the distillation product.

[0026] The connecting block is in an inverted T-shape. When the threaded tube 10 is threadedly connected to the connecting block, the threaded tube 10 rotates and abuts against the bottom of the connecting block to complete the fixation of the two. When the connecting shaft 9 rotates and the threaded tube 10 continues to be locked, the connecting shaft 9 drives the threaded tube 10 to rotate through the connecting block.

[0027] There are multiple porous disks 7 , and there are multiple supporting mechanisms, connecting blocks, and structures connected to the connecting blocks, which correspond one to one to the multiple porous disks 7 .

[0028] The piercing assembly includes a rotating shaft 17 rotatably connected to the mounting block 16 , and a plurality of fixing needles 18 are fixedly connected to the outer side of the rotating shaft 17 .

[0029] Multiple fixed pins 18 are distributed in a circular array on the outside of the rotating shaft 17. Multiple toggle components are connected to the mounting block 16. The multiple toggle components correspond one-to-one to the multiple columns of fixed pins 18 along the axial direction of the rotating shaft 17.

[0031] The push plate 19 is slidably engaged with the rotating shaft 17 via the T-shaped rod 34 , thereby preventing the push plate 19 from being separated from the fixing needle 18 .

[0032] The flipping assembly includes a rotating connecting part 26 rotatably connected to the two ends of the flipping part. The rotating connecting 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. Among the two electric push rods, one is fixedly connected to the mounting plate, and the other is fixedly connected to a strap 32. The end of the strap 32 away from the electric push rod rests on the top of the end face gear ring 12.

[0033] The flap portion is supported by the strap 32 to prevent the flap portion from being cantilevered, thereby improving the stability of the flap portion during movement.

[0034] The flipping part includes an arc-shaped plate 33 and a connecting rod 29 fixedly connected to both ends of the arc-shaped plate 33. The connecting rod 29 is L-shaped. The two connecting rods 29 are coaxially arranged at one end away from the arc-shaped plate 33 and rotate coaxially with the corresponding rotating ring. The arc-shaped plate 33 is arc-shaped, and its rotating front end is wedge-shaped, and the back end is fixedly connected to a plurality of hemispherical extrusion blocks. A plurality of protrusions 15 are fixedly connected to the upper surface of the porous disk 7. The plurality of hemispherical extrusion blocks and the plurality of protrusions 15 in the same radial direction on the porous disk 7 are staggered.

[0035] A plurality of protrusions 15 are distributed in a circular array on the porous disk 7, and the number of the protrusions 15 is significantly smaller than the number of holes in the porous disk 7, and cooperate with the hemispherical squeezing blocks to form an auxiliary squeezing operation on the ginger slices.

[0036] A sliding housing 28 is slidably connected to the side of the threaded tube 10, and 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 the connecting rod 29, and a limit hole is provided on the limit block 30. A second electric telescopic rod 27 is installed on the mounting plate, and the output end of the second electric telescopic rod 27 is extended and engaged with the limit hole.

[0037] The encoder adopts existing technology to determine the angle of the connecting rod 29 connected thereto, so as to facilitate the control of the angle of the arc plate 33 to cooperate with the squeezing operation of the ginger slices.

[0038] The edge of the porous disk 7 is fixedly connected to a blocking ring 11, and the top is coaxially rotatably connected to a blocking ring plate 13. The blocking ring 11 rests against the inner wall of the heating tank 5. An annular groove is formed between the blocking ring 11 and the blocking ring plate 13. The first bevel gear 31 and the second bevel gear 36 are both located inside the annular groove. The blocking ring plate 13 is provided with a strip groove for the movement of the rotating shaft 17 and the connecting rod 29.

[0039] The first bevel gear 31 and the second bevel gear 36 are blocked by the blocking ring 11 and the blocking ring plate 13. When the rotating shaft 17 and the connecting rod 29 rotate axially around the threaded tube 10, the blocking ring plate 13 is driven to move accordingly, thereby limiting the ginger slices on the porous disk 7 and preventing the ginger slices from falling off the porous disk 7.

[0040] The other end of the rotating shaft 17 away from the mounting block 16 rests on the blocking ring 11, which effectively prevents the rotating shaft 17 from being cantilevered and improves its stability during movement.

[0041] When the present invention is used, the heating tank 5 is connected to the separating funnel 4 through the condenser. During the distillation process, the mixed steam generated in the heating tank 5 enters the interior of the separating funnel 4 through the condenser, and the condenser passes through the interior of the water storage container 3.

[0042] Cold water is continuously supplied to the water storage container 3 through the refrigerator 2, so that the mixed steam inside the condenser tube is liquefied and eventually enters the separatory funnel 4 to complete the collection.

[0043] Before starting distillation, the motor 8 is fixedly arranged below the heating tank 5 through external support, and the connecting shaft 9 is sealed and rotatably connected to the lower end of the heating tank 5.

[0044] The support block 24 can be completely retracted into the interior of the mounting shell 14, which can prevent the support block 24 from blocking the installation operation of the porous disk 7. Under the elastic force of the spring 25, the support block 24 extends out of the interior of the mounting shell 14, so that the support block 24 can support the porous disk 7 and place the porous disk 7 on the upper end of the three groups of support blocks 24.

[0045] The threaded tube 10 is then 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 abutted together. At this time, the connecting shaft 9 rotates, driving the threaded tube 10 to rotate through the connecting block, and 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 blocking ring plate 13.

[0046] The strip grooves on the shielding ring plate 13 are provided for the installation of the rotating shaft 17 and the connecting rod 29. Then the end face gear ring 12 is fixedly set on the inner wall of the heating tank 5 so that the end face gear ring 12 is located above the first bevel gear 31 and the second bevel gear 36. The strap 32 is then fixedly connected or threadedly connected to the upper end of the corresponding rotating connection part 26 so that the strap 32 contacts the upper end of the end face gear ring 12. At this time, the end face gear ring 12 can support the strap 32 and maintain the stability of the movement of the arc plate 33.

[0047] After the three porous plates 7 and the corresponding structures are installed in sequence, the ginger slices are placed on the upper surface of the porous plate 7 to complete the preparation work. In the subsequent distillation process, the loading and unloading operations of the ginger slices are completed by disassembling the side door 6 until the distillation is completed.

[0048] When the ginger slices are distilled, the ginger slices are evenly placed in multiple layers on the porous plate 7. The motor 8 is working, and its output end drives the connecting shaft 9 to rotate, which drives the mounting block 16 and the mounting plate to rotate through the connecting block and the threaded tube 10.

[0049] When the mounting block 16 rotates with the threaded tube 10, the rotating shaft 17 is driven to rotate around the threaded tube 10. At the same time, the second bevel gear 36 on the rotating shaft 17 engages with the end face gear ring 12, causing the rotating shaft 17 to rotate, driving the fixed needle 18 to rotate and roll the upper layer of ginger slices on the porous disk 7. When the fixed needle 18 rotates to the bottom of the rotating shaft 17, it penetrates into the upper layer of ginger slices, increasing the surface area and porosity of the ginger slices, making 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 the essential oil.

[0050] When the fixing pin 18 continues to rotate with the rotating shaft 17, the corresponding third electric telescopic rod 35 works, and its output end extends, driving 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 adhering to the fixing pin 18 and moving with it, thereby ensuring the use effect of the fixing pin 18.

[0051] When the mounting plate rotates with the threaded tube 10, the turning part is driven to rotate around the threaded tube 10, and the first bevel gear 31 on the connecting rod 29 engages with the end face gear 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 turn the ginger slices.

[0052] During the distillation process, the first electric telescopic rod 21 works, 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 porous plate 7.

[0053] The electric push rods in the two rotating connecting parts 26 work, and the output ends thereof drive the connecting rod 29 to move up and down through the rotating ring, so that the height of the arc plate 33 can be adjusted.

[0054] The distillation process includes deep turning operation, shallow turning operation and squeezing operation.

[0055] Deep turning operation: control the arc plate 33 to move upward to the upper limit position, so that the first bevel gear 31 is engaged with the end face gear ring 12, and control the porous disk 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 is inserted between the ginger slices and the upper surface of the porous disk 7, scooping up the ginger slices, and turning the scooped ginger slices as the arc plate 33 rotates until the ginger slices between the two groups of protrusions 15 are turned over, so that the ginger slices on the porous disk 7 are dispersed more evenly, avoiding the agglomeration and adhesion of the ginger slices, and at the same time displacing the positions of the ginger slices to a certain extent, making it easier for the piercing component to pierce the ginger slices more evenly.

[0056] When the arc plate 33 encounters the protrusion 15, the hemispherical squeezing block on the arc plate 33 rotates toward the protrusion 15, and multiple hemispherical squeezing blocks and multiple protrusions 15 move alternately, further squeezing the ginger slices between the two to destroy the cell structure of the ginger slices, thereby improving the extraction efficiency of the essential oil.

[0057] Shallow flipping operation: Since ginger slices need a certain amount of time to absorb and transfer heat during the heating process, if they are flipped too frequently and quickly, this heat transfer process may be interrupted, 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 porous disk 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 flip the stacked upper layer of ginger slices, while the lower layer of ginger slices is less affected by the flipping, and continuous heating promotes the discharge of essential oils.

[0058] Extrusion operation: control the arc plate 33 to move downward to the lower limit position, so that the first bevel gear 31 is separated from the end face gear ring 12, and control the porous 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 porous disk 7. The arc plate 33 is located at the angle of the connecting rod 29 detected by the encoder. When the connecting rod 29 is placed vertically so that the outer side of the arc plate 33 faces downward, the output end of the second electric telescopic rod 27 is controlled to extend and embed into the limit block 30, locking the connecting rod 29 to fix the angle of the arc plate 33. In the process of the arc plate 33 rotating around the threaded tube 10, the output end of the electric push rod is controlled 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 by squeezing.

[0059] By cyclically turning over, turning over and squeezing, the ginger slices on the porous plate 7 are intermittently pierced, turned over and squeezed. Compared with the traditional stirring and turning method of stirring blades, it is more gentle and causes less damage to the ginger slices, ensuring full contact between the ginger slices and the steam, reducing damage to the ginger slices, improving the extraction efficiency and quality of the essential oil, and reducing the occurrence of debris and impurities.

[0060] 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 in the scope of protection of the present invention.
