Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea essential oil distillation extraction device. Background Technology

[0002] Tea essential oil is a natural plant essence extracted from tea leaves, possessing a fresh and elegant aroma and multiple benefits. Rich in active ingredients such as tea polyphenols, caffeine, and vitamins, it effectively combats oxidation, bacteria, and inflammation, helping to improve skin condition and delay aging. The refreshing aroma of tea essential oil has a stimulating and stress-relieving effect, often used in aromatherapy to help relax the mind and body and improve concentration. The extraction method for tea essential oil involves steam distillation. Fresh or dried tea leaves are placed in a still, heated from below, and steam is introduced to evaporate the essential oil. The water vapor containing the essential oil is collected and cooled through a conduit, condensing into a liquid. The water is then separated from the essential oil based on the difference in specific gravity and density.

[0003] For example, Chinese Patent Publication No. CN213192552U discloses a tea distillation apparatus, including a distillation tank. A first distillation drawer is located in the upper part of the inner cavity of the distillation tank. A supporting flange is located at the bottom end of the first distillation drawer. A filter screen is located at the bottom end of the first distillation drawer. A second distillation drawer is located at the bottom of the first distillation drawer, and a second supporting flange is located at the bottom end of the second distillation drawer. Beneficial effects: High-temperature gas generated by a heating device is introduced into the distillation tank through the blowing action of a blower, producing distillation gas, which can distill the tea leaves above, improving the distillation efficiency of the tea.

[0004] When the tea distillation extraction device described in the above application is in use, the tea leaves are left to accumulate in the distillation drawer, making it difficult for water vapor to come into uniform contact with the tea raw materials. The water vapor cannot fully enter the interior of the tea leaves, and some of the tea raw materials are prone to clogging the ventilation holes on the filter screen at the bottom of the distillation drawer to a certain extent, affecting the flow of steam and the fullness and efficiency of tea essential oil extraction.

[0005] Therefore, it is necessary to provide a tea essential oil distillation extraction device to solve the above-mentioned technical problems. Utility Model Content

[0010] As a further embodiment of this utility model, the second protrusion is provided in multiple forms, and the multiple second protrusions are arranged in a ring.

[0011] As a further embodiment of this utility model, a lever is fixed on the inner wall of the built-in cylinder, and multiple levers are provided and the multiple levers are distributed in a ring.

[0013] As a further embodiment of this utility model, an exhaust pipe communicating with the interior of the processing cylinder is fixed at the top end of the processing cylinder, and a cover plate is hinged to the open end of the processing cylinder.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Please see Figure 1-5This utility model provides a tea essential oil distillation and extraction device, including a base plate 12, a processing cylinder 3 with an open end fixed to the top of the base plate 12, an inner cylinder 14 inside the processing cylinder 3, and multiple equally spaced through holes 17 on the side of the inner cylinder 14. A support plate 6 located on the closed end side of the processing cylinder 3 is fixed to the top of the base plate 12, and a drive motor 9 for driving the inner cylinder 14 to rotate is fixed to the support plate 6. A mounting assembly 1 is provided between the drive motor 9 and the inner cylinder 14. A wall-tapping assembly 2 is provided outside the inner cylinder 14. A gas supply pipe 18 is inserted into the bottom of the processing cylinder 3, and a [missing information - likely a device or component] is provided at the top of the gas supply pipe 18. Multiple air outlet pipes 19 are provided, and an air inlet pipe 13 is connected to the air delivery pipe 18. An exhaust pipe 4, communicating with the interior of the processing cylinder 3, is fixed to the top of the processing cylinder 3. A cover plate 5 is hinged to the open end of the processing cylinder 3. In use, the cover plate 5 is first opened, then the tea leaves are placed into the inner cylinder 14, and then the cover plate 5 is closed. A steam generator is connected to the air inlet pipe 13, and steam is delivered to the interior of the processing cylinder 3 through the air inlet pipe 13, air delivery pipe 18, and air outlet pipes 19. The through-hole 17 is set to be smaller than the minimum area of ​​a tea leaf. The steam inside the processing cylinder 3 rises and passes through the multiple through-holes 17 into the inner cylinder 14, thereby steaming the essential oils from the tea leaves. The steam containing essential oils is emitted and collected through exhaust pipe 4. The steam is cooled into a liquid, and the essential oil components are separated based on the difference in specific gravity and density between water and essential oils. During this process, the output of drive motor 9 drives pinion 10 to rotate, which in turn drives shaft 8 through the interaction of pinion 10 and large gear 7. Shaft 8 drives the inner cylinder 14 to rotate synchronously, causing the tea leaves inside the inner cylinder 14 to continuously agitate, increasing the uniformity of contact between steam and tea leaves, effectively improving the fullness of tea essential oil distillation and extraction efficiency. Simultaneously, the wall-tapping component 2 provides internal... The side wall of the inner cylinder 14 is continuously struck, causing it to vibrate and allowing the tea leaves adhering to its inner wall to fall back into the inner cylinder 14. This prevents the tea leaves from clogging the through hole 17 and further improves the contact between the tea leaves and steam, thus enhancing the uniformity of tea oil distillation and extraction. After the tea oil distillation and extraction is complete, the inner cylinder 14 can be removed from the processing cylinder 3 by opening the cover plate 5 and using the assembly 1. This facilitates the removal of tea residue from the inner cylinder 14, making the slag removal operation convenient and improving efficiency.

[0028] Further as Figure 2 , Figure 3 and Figure 5As shown, it is worth noting that a shaft 8 is rotatably connected to the support plate 6, a large gear 7 is fixed to one end of the shaft 8, and a small gear 10 that meshes with the large gear 7 is fixed to the output end of the drive motor 9. The mounting assembly 1 includes an insert rod 101 fixed to one end of the inner cylinder 14 and arranged coaxially with the inner cylinder 14. The insert rod 101 is inserted into the shaft 8, and a locking bolt 102 is threaded onto the side of the shaft 8. The screw end of the locking bolt 102 contacts the side of the insert rod 101. In use, by inserting the insert rod 101... Insert the insert rod 101 into the shaft 8 and tighten the locking bolt 102 to lock the insert rod 101 and the shaft 8 into one piece. The rotating shaft 8 will drive the inner cylinder 14 to rotate synchronously. After the tea essential oil distillation and extraction process is completed, open the cover plate 5 and unscrew the locking bolt 102 to release the lock of the insert rod 101 in the shaft 8. The inner cylinder 14 can then be removed from the processing cylinder 3 as a whole, making it convenient to pour out the tea residue inside the inner cylinder 14. The slag discharge operation is convenient and the slag discharge efficiency is improved.

[0029] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the wall-tapping assembly 2 includes a ring 204 fixed to the outer wall of the inner cylinder 14. A second protrusion 203 is fixed to the side of the ring 204. A metal spring plate 201 is fixed to the inner wall of the processing cylinder 3. A first protrusion 202 that slides with the second protrusion 203 is fixed to the end of the metal spring plate 201 away from the inner wall of the processing cylinder 3. When the inner cylinder 14 rotates, the inner cylinder 14 drives the ring 204 to rotate synchronously, thereby causing the second protrusion 203 and the first protrusion 202 to slide with each other. 202 forms a relative rotation, and through the cooperation of the metal spring plate 201, the first protrusion 202 and the second protrusion 203, the first protrusion 202 continuously knocks on the side wall of the inner cylinder 14, thereby causing the side wall of the inner cylinder 14 to vibrate continuously, so that the tea raw material adhering to the inner side wall of the inner cylinder 14 continuously falls back into the inner cylinder 14, preventing the tea raw material from clogging the through hole 17, while further improving the full contact between the tea raw material and the steam, and further improving the uniformity of tea essential oil distillation extraction.

[0030] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that a deflector plate 15 is fixed on the inner wall of the inner cylinder 14. Multiple deflector plates 15 are arranged in a ring. In actual operation, the deflector plates 15 continuously move the tea raw materials inside the inner cylinder 14 upward and then downward, thereby increasing the movement of the tea raw materials, further improving the uniformity of steam-tea contact, and further improving the tea essential oil distillation extraction effect.

[0031] This solution involves the following steps: First, open the cover plate 5, then place the tea leaves into the inner cylinder 14, and then close the cover plate 5. Steam is then transported to the processing cylinder 3 through the air inlet pipe 13, air outlet pipe 18, and air outlet pipe 19. The steam inside the processing cylinder 3 rises and passes through multiple through holes 17 into the inner cylinder 14, thereby evaporating the essential oils from the tea leaves. The steam containing essential oils is discharged and collected through the exhaust pipe 4. The steam is cooled into a liquid, and the essential oil components are separated according to the difference in specific gravity and density between water and essential oils. During this process, the output of the drive motor 9 drives the pinion 10 to rotate, which in turn drives the shaft 8 to rotate through the cooperation of the pinion 10 and the large gear 7. The shaft 8 drives the inner cylinder 14 to rotate synchronously, causing the paddle plate 15 to continuously lift and then drop the tea leaves inside the inner cylinder 14, thereby increasing the movement of the tea leaves and making the tea leaves inside the inner cylinder 14 more uniform. The material is constantly turned over, increasing the uniformity of contact between steam and tea raw materials. When the inner cylinder 14 rotates, it drives the ring 204 to rotate synchronously, so that the second protrusion 203 and the first protrusion 202 rotate relative to each other. Through the cooperation of the metal spring plate 201, the first protrusion 202 and the second protrusion 203, the first protrusion 202 continuously knocks on the side wall of the inner cylinder 14, so that the side wall of the inner cylinder 14 continuously vibrates, causing the tea raw materials adhering to the inner side wall of the inner cylinder 14 to continuously fall back into the inner cylinder 14, preventing the tea raw materials from clogging the through hole 17 and further improving the full contact between the tea raw materials and steam. After the tea essential oil distillation and extraction process is completed, the cover plate 5 is opened, and the locking bolt 102 is unscrewed to release the locking of the insertion rod 101 in the shaft 8, so that the inner cylinder 14 can be removed from the processing cylinder 3, making it convenient to pour out the tea residue inside the inner cylinder 14.

[0032] Further as Figure 5 As shown, it is worth noting that there are multiple second protrusions 203 arranged in a ring shape. In actual operation, the multiple second protrusions 203 effectively increase the frequency of the first protrusion 202 striking the side wall of the inner cylinder 14, thereby improving the vibration effect of the inner cylinder 14.

[0033] Further as Figure 5 As shown, it is worth noting that two symmetrically distributed handles 16 are fixed at the open end of the built-in cylinder 14; during operation, the built-in cylinder 14 can be easily removed from the inside of the processing cylinder 3 by means of the handles 16, which facilitates operation.

[0034] In summary: The rotation of the inner cylinder 14 continuously agitates the tea leaves inside, increasing the uniformity of steam-tea contact and effectively improving the extraction efficiency of tea essential oils. Simultaneously, the continuous tapping of the inner cylinder 14's sidewalls by the wall-tapping component 2 causes continuous vibration, allowing the tea leaves adhering to the inner wall to fall back into the inner cylinder 14. This prevents the tea leaves from clogging the through-hole 17 and further enhances the contact between the tea leaves and steam, further improving the uniformity of tea essential oil extraction. After the tea essential oil extraction is complete, the inner cylinder 14 can be removed from the processing cylinder 3 by opening the cover plate 5 and using the connecting component 1, facilitating the removal of tea residue. This convenient and efficient slag removal operation improves slag removal efficiency.

[0035] The drive motor 9 can be purchased from the market. The drive motor 9 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
