[0025] The following describes an embodiment of this utility model based on its overall structure.

[0026] like Figures 1 to 4As shown, this utility model provides a low-temperature condensation extraction device for Sichuan pepper essential oil, including a condenser tank 2. A connecting pipe 15 is fixedly installed below the condenser tank 2, and a rotating shaft 16 is fixedly installed below the connecting pipe 15. An adjusting plate 17 is rotatably installed below the rotating shaft 16. An adjusting groove 22 is opened inside the adjusting plate 17, and an adjusting rod 19 is fixedly installed on the outside of the adjusting plate 17. An adjusting column 21 is slidably installed inside the adjusting plate 17, and a baffle 20 is fixedly installed below the adjusting column 21. The connecting pipe 15 below the condenser tank 2 is connected to the adjusting plate 17 through the rotating shaft 16. The adjusting groove 22, adjusting column 21, and baffle 20 in the adjusting plate 17 can control the flow rate and flow of the condensate. When the adjusting rod 19 rotates the adjusting plate 17, the baffle 20 can slide in the square groove 23 of the fixed plate 18. With the screw connection of the threaded pipe 27 to the separator 3, the condensate can be flexibly controlled to enter the separator 3.

[0027] In this embodiment, a fixing plate 18 is fixedly installed below the adjusting plate 17, and the fixing plate 18 is slidably disposed with the baffle 20. A square groove 23 is opened inside the fixing plate 18. A fixing plate 24 is fixedly installed on the right side of the baffle 20. A fixing rod 25 is fixedly installed inside the fixing plate 24, and the fixing rod 25 is fixedly disposed with the fixing plate 18. A threaded tube 27 is fixedly installed below the fixing plate 18, and the baffle 20 is slidably disposed with the threaded tube 27. A separator 3 is spirally installed below the threaded tube 27. A threaded condenser is fixedly installed inside the condenser tank 2. The condenser 7 has an inlet 5 at the top and an outlet 26 at the bottom. A connecting pipe 6 is fixed to the outside of the condenser 2. A threaded condenser pipe 7 is installed inside the condenser 2, increasing the condensation area. Combined with the circulation design of the inlet 5 and outlet 26, the steam temperature can be quickly reduced, achieving efficient condensation and liquefaction of the Sichuan pepper essential oil steam and reducing the evaporation loss of the essential oil during condensation. A connecting pipe 10 is attached to the right side of the connecting pipe 6. The connecting pipe 10 has a threaded rod 11 spirally arranged inside, and the threaded rod 11 is connected to the connecting pipe 6. The first tube 6 is spirally arranged, and the extraction tank 1 is fixedly installed on the right side of the second connecting tube 10. The first threaded tube 8 is fixedly installed above the extraction tank 1, and the feed pipe 9 is spirally connected to the outside of the first threaded tube 8. The first connecting tube 6 and the second connecting tube 10 are spirally connected by a threaded rod 11. The first threaded tube 8 above the extraction tank 1 is spirally connected to the feed pipe 9. This detachable design facilitates the installation, cleaning and maintenance of the equipment, avoids the accumulation of raw material residue or impurities affecting the extraction effect, and also facilitates the replacement of components of different specifications to meet different production needs. A heating plate 12 is fixedly installed inside the extraction tank 1. The independent condensation design of the condenser tank 2, combined with the low-temperature control of the extraction tank 1, utilizes the heating plate 12 to precisely control the temperature, maintaining the entire extraction process under low-temperature conditions.

A motor 14 is fixedly installed below the extraction tank 1, and a stirring rack 13 is fixedly installed at the end of the main shaft of the motor 14.

A support frame 4 is fixedly installed on the outside of the extraction tank 1.

[0028] Working principle and process of low-temperature condensation extraction device for Sichuan pepper essential oil:

[0029] When using the low-temperature condensation extraction device for Sichuan pepper essential oil, the connecting pipe 6 and the connecting pipe 10 are screwed together using the threaded rod 11 to ensure a sealed connection between the condensation tank 2 and the extraction tank 1. The feed pipe 9 is then screwed onto the extraction tank 1. On the upper threaded pipe 1 8, ensure the raw material feeding channel is unobstructed. Below the threaded pipe 2 27, a separator 3 is spirally installed for subsequent separation of essential oil and solvent. Check that all component connections are secure to prevent leaks during operation. After installation, cooling water is introduced through the inlet 5 above the condenser tank 2. The water flows through the threaded condenser pipe 7 and out through the outlet 26 below, forming a circulating cooling system to lower the internal temperature of the condenser tank 2 in advance, preparing for the subsequent condensation process. An appropriate amount of extraction solvent is injected into the extraction tank 1, ensuring the solvent fully submerges the pepper raw material. The heating plate 12 inside the extraction tank 1 is activated, and a suitable low-temperature heating temperature is set to ensure full contact between the solvent and the pepper raw material. Simultaneously, the motor 14 below the extraction tank 1 is turned on, driving the stirring rack 13 to rotate, accelerating the dissolution of the pepper essential oil components by the solvent and improving extraction efficiency. The steam containing pepper essential oil generated during the extraction process enters the condenser tank 2 through connecting pipe 1 6 and connecting pipe 2 10. The steam encounters cooling on the surface of the threaded condenser pipe 7 inside the condenser tank 2. With the continuous circulation of water, the steam rapidly liquefies into a liquid mixture of Sichuan pepper essential oil, which flows down the wall of the condenser tube and enters the area of ​​the lower regulating plate 17 through the connecting pipe 15. The operator rotates the regulating rod 19 on the outside of the regulating plate 17, causing the regulating plate 17 to rotate. The regulating column 21 inside the regulating plate 17 slides in the regulating groove 22, thereby controlling the left and right movement of the baffle 20 in the square groove 23 of the fixed plate 18, adjusting the gap, and thus controlling the flow rate of the condensate into the separator 3. The liquid mixture of Sichuan pepper essential oil enters the separator 3 through the threaded pipe 27. Utilizing the density difference or other physical property differences between the essential oil and the solvent, the Sichuan pepper essential oil and the solvent are separated in the separator 3, and finally the pure Sichuan pepper essential oil product is collected. The separated solvent can be recycled and reused as needed. After the work is completed, the feed pipe 9, connecting pipe 1 6 and connecting pipe 2 10, separator 3 and other components are disassembled in sequence, and the extraction tank 1, condenser tank 2 and all connecting pipes are cleaned to remove residual raw materials and solvents and prevent impurities from affecting the next extraction effect.
