Description

Technical Field

[0001] This utility model relates to the field of tangerine peel essential oil extraction, and in particular to a tangerine peel essential oil extraction device. Background Technology

[0002] Tangerine peel essential oil is a volatile plant extract derived from dried tangerine peel (Chenpi). It is typically obtained by grinding tangerine peel into powder, sieving it, and then soaking it in a eutectic solvent for purification. This involves soaking the tangerine peel powder in a solvent for extraction. However, due to the tendency of tangerine peel essential oil to hydrolyze upon heating, extraction can only be performed using low-temperature soaking, resulting in low extraction efficiency, high residue of active ingredients, and potential waste of raw materials. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a device for extracting tangerine peel essential oil.

[0005] The mixing tank has an opening at the top and is provided with a cover for sealing the opening. The stirring assembly includes a stirring shaft and a stirring element. The stirring shaft is located inside the mixing tank and one end of the stirring shaft passes through the cover. The cover and the stirring shaft are sealed by a first sealing element. The stirring shaft is driven by a linear motor to move back and forth in the depth direction of the mixing tank. When the stirring shaft moves, it drives the stirring element to move.

[0006] The pressurizing component is mounted on the stirring shaft and moves back and forth within the mixing tank along the depth direction of the mixing tank. When the pressurizing component moves downward, the pressure inside the mixing tank increases.

[0007] The stirring component includes a stirring block, which is fixedly connected to the stirring shaft. The side wall of the stirring block abuts against the inner wall of the mixing tank. A plurality of mixing holes are formed on the stirring block, and the mixture flows through the mixing holes when the stirring block moves.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Reference Figures 1-3 A device for extracting tangerine peel essential oil includes a mixing tank 1, which contains a stirring component 3 and a pressurizing component 2. The pressurizing component 2 pressurizes the mixing tank, and the stirring component 3 is disposed within the mixing tank 1 to stir the mixture. In this embodiment, the mixing tank 1 has an opening at the top and is equipped with a cap 11 to seal the opening, thus forming a sealed space inside the mixing tank. Before sealing with the cap 11, the mixture of solvent and tangerine peel powder needs to be fed into the mixing tank 1 through the opening for extraction. To accelerate the extraction speed, the stirring component 3 can be used to stir the mixture after the cap 11 is sealed, ensuring sufficient contact between the tangerine peel powder and the solvent. Furthermore, during the stirring process, the pressurizing component 2 can be used to pressurize the mixing tank 1 to accelerate the precipitation of essential oil from the tangerine peel powder, thereby improving the extraction efficiency.

[0020] In this embodiment, the stirring assembly 3 includes a stirring shaft 32 and a stirring element. The stirring shaft 32 is disposed inside the mixing tank 1, and one end of the stirring shaft 32 passes through the cover 11. The cover 11 and the stirring shaft 32 are sealed by a first sealing element, which can be an O-ring seal. Other existing sealing methods can also be used, but the most economical approach is still to seal the gap with multiple O-ring seals. This provides better sealing of the mixing tank 1 during the extraction process, reduces the influence of the external environment, and allows for higher pressurization, thereby improving the extraction efficiency.

[0021] In this embodiment, the stirring shaft 32 is driven by a linear motor 35 to reciprocate within the mixing tank 1 in the depth direction of the mixing tank 1. The linear motor 35 is fixed to the cover 11, and the stirring shaft 32 extends into the mixing tank 1. The movement of the stirring shaft 32 drives the stirring components to move. The corresponding stirring components include a stirring block 31, which is fixedly connected to the stirring shaft 32. The side wall of the stirring block 31 abuts against the inner wall of the mixing tank 1. Several mixing holes 33 are formed on the stirring block 31, and the mixture flows through the mixing holes 33 when the stirring block 31 moves. That is, the stirring shaft 32 moves in the mixing tank 1 by extension and retraction. Initially, the stirring block 31 is flush with the liquid surface of the mixture. As the stirring shaft 32 extends and retracts, the stirring block 31 is pressed down, and the mixture overflows from the mixing holes 33 to the top of the stirring block 31. This method makes the tangerine peel powder and solvent mix more evenly and simultaneously begins to compress the tangerine peel powder, resulting in more thorough extraction of tangerine peel essential oil and less residue. To prevent the mixture from being squeezed and left behind in the gaps, a sealing ring 34 is provided on the outer wall of the stirring block 31 that contacts the mixing tank 1. The sealing ring 34 is pressed tightly against the inner wall of the mixing tank 1. This ensures that when the stirring block 31 is pressed down, the mixture can only flow out from the mixing hole 33, resulting in better mixing effect and less residue in the mixing tank 1, making it easier to clean after extraction.

[0022] In this embodiment, while the stirring block 31 is stirring, the pressurizing component 2 is mounted on the stirring shaft 32 and reciprocates within the mixing tank 1 along its depth direction. As the pressurizing component 2 moves downwards, the pressure within the mixing tank 1 increases. Specifically, the pressurizing component 2 includes a pressure plate 21 and a driving member 22. The pressure plate 21 is located within the mixing tank 1, with its edge abutting against the inner wall of the mixing tank 1. The driving member 22 is mounted on the cover 11, with one end passing through the cover 11 and connecting to the pressure plate 21. A perforation is provided on the pressure plate 21 for the stirring shaft 32 to pass through. A second sealing member 23 is provided between the inner wall of the perforation and the stirring shaft 32 to seal the gap between the perforation and the stirring shaft 32. The second sealing member 23 can also be an O-ring. The driving member 22 drives the pressure plate 21 to reciprocate along the length direction of the stirring shaft 32. The driving component 22 includes a drive motor 221 and a lead screw 222. The drive motor 221 is fixed on the cover 11. A sliding sleeve 223 is fitted on the lead screw 222. A sleeve hole is opened on the drive motor 221. The sliding sleeve 223 is located in the sleeve hole and rotates in the sleeve hole. A transmission gear 224 is fixed on the sliding sleeve 223. The drive motor 221 drives the sliding sleeve 223 to rotate through gear meshing. The lead screw 222 passes through the sleeve hole and extends into the mixing tank 1. A rotation hole 225 is opened on the pressure plate 21. The lead screw 222 is inserted into the rotation hole 225 and rotates in the rotation hole 225. The drive motor 221 drives the sliding sleeve 223 to rotate in the sleeve hole through gear meshing, thereby realizing the reciprocating extension and retraction of the lead screw 222, which in turn drives the pressure plate 21 to press down. When the pressure plate 21 presses down, since it is sealed with the inner wall of the mixing tank 1, the usable area in the sealed tank becomes less and less, that is, the pressure becomes higher and higher, so that the extraction is stirred under high pressure, thereby improving the extraction efficiency.

[0023] To limit the travel of the pressure plate 21 and prevent excessive pressure in the mixing tank 1, a limiting hole 24 is made on the outer wall of the stirring shaft 32 along its length. A limiting block 25 is provided on the inner wall of the hole corresponding to the position of the limiting hole 24. The limiting block 25 is inserted into the limiting hole 24. When the pressure plate 21 moves back and forth, it drives the limiting block 25 to move back and forth within the limiting hole 24. That is, during the actual pressurization process, the pressure plate 21 can only move within the range of the limiting hole 24 to avoid excessive pressure that could damage the tank body of the mixing tank 1.

[0024] Compared to existing technologies, this invention allows for the mixing of the mixture using a stirring assembly 3 after the cap 11 is sealed, ensuring full contact between the tangerine peel powder and the solvent. Furthermore, during the stirring process, a pressurizing assembly 2 can be used to pressurize the mixing tank 1, accelerating the extraction of essential oils from the tangerine peel powder and thus improving extraction efficiency.

[0025] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
