Description

Technical Field

[0001] This utility model relates to the field of saponification equipment technology, specifically to a continuous saponification equipment for lutein extract. Background Technology

[0002] Lutein extract is a dark brown viscous liquid extracted from marigold granules. It is mainly used for deep processing to produce pure natural lutein or crystals, and can be used as a food additive. It is widely used in food, feed and other fields. In the production and deep processing of lutein extract, saponification is the core link connecting "extract extraction" and "high-purity lutein preparation". The principle of saponification is to use the catalytic effect of strong base (such as NaOH, KOH) to cause "ester bond hydrolysis" of lutein ester. It is usually carried out in a reaction vessel. Lutein extract and strong base solvent are added to the reaction vessel and mixed during heating and stirring in the reaction vessel jacket. Finally, the products (the upper layer is the organic phase and the lower layer is the aqueous phase) are separated. Existing saponification equipment can achieve continuous saponification of lutein extract through continuous material conveying, reaction vessel internal environment control and continuous product separation. However, the existing stirring structure in the reaction vessel is driven by a motor and reducer to drive the main shaft to rotate the stirring paddle to disperse and mix the various materials in the reaction vessel. It is similar to a "ceiling fan". Although it is practical, the structure is simple and the stirring and mixing effect of the materials in the reaction vessel is not good. Utility Model Content

[0003] This invention proposes a continuous saponification device for lutein extract, which solves the problem in the prior art that uses a motor and reducer to drive the main shaft to rotate the stirring paddle to disperse and mix various materials in the reaction vessel. The structure is simple, but the mixing effect of the materials in the reaction vessel is not good.

[0004] The technical solution of this utility model is as follows: A continuous saponification apparatus for lutein extract includes a reaction vessel with a main shaft rotatably mounted inside. The apparatus also includes a rotating frame, a fixed plate, a dispersing plate, and a stirring mechanism. One end of the rotating frame is fixedly connected to one end of the main shaft. The fixed plate is fixedly mounted inside the rotating frame and coaxially with the main shaft. Multiple dispersing plates are longitudinally arranged at both ends of the fixed plate to laterally disperse the material in conjunction with the rotation of the main shaft. The stirring mechanism is mounted on the fixed plate to fully stir the mixture in conjunction with the rotation of the main shaft.

[0005] Preferably, the stirring mechanism includes a rotating shaft, a mounting sleeve, a stirring paddle, and a driving assembly. Multiple rotating shafts are longitudinally arranged at both ends of the fixed plate where the dispersion plate is not provided. Multiple mounting sleeves are evenly arranged along the axial direction on the rotating shaft. The mounting sleeves are coaxially fixedly connected to the rotating shaft. Multiple stirring paddles are circumferentially fixedly connected to the mounting sleeves. The driving assembly is disposed on the fixed plate and is used to drive the multiple rotating shafts to rotate.

[0006] Furthermore, the drive assembly includes a drive shaft, a driving bevel gear, a driven bevel gear, and a drive motor.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0015] like Figures 1-5 As shown, this embodiment proposes a continuous saponification device for lutein extract, including a reaction vessel 1, a main shaft 3 rotatably arranged inside the reaction vessel 1, and a rotating mechanism 2 arranged at the top of the reaction vessel 1 for driving the main shaft 3 to rotate. The rotating mechanism 2 includes a servo motor, a reducer and a coupling, and also includes a rotating frame 4, a fixing plate 5, a dispersing plate 6 and a stirring mechanism. like Figure 4As shown, the center of one end of the rotating frame 4 is fixedly connected to one end of the main shaft 3. Both ends of the rotating frame 4 are provided with snap-fit ​​grooves 17. A snap-fit ​​plate 18 is detachably installed in the snap-fit ​​groove 17 by locking bolts 20. A scraper 19 is fixedly connected to the snap-fit ​​plate 18. The contact surface between the scraper 19 and the inner wall of the reactor 1 is provided with a flexible material to avoid scratching the inner wall of the reactor 1. The scraper 19 fits and slides against the inner wall of the reactor 1. By opening the cover at the top of the reactor 1, the scraper 19 is inserted along the inner wall of the reactor 1. Inside the reactor 1, the scraper 19 drives the snap-fit ​​plate 18 to insert into the snap-fit ​​groove 17. Then, the snap-fit ​​plate 18 and the rotating frame 4 are locked and fixed with the locking bolt 20. At this time, the two ends of the scraper 19 are respectively attached to the rotating frame 4 and the inner wall of the reactor 1. The rotating mechanism 2 drives the main shaft 3 to rotate, the main shaft 3 drives the rotating frame 4 to rotate, and the rotating frame 4 drives the two scrapers 19 to rotate along the inner wall of the reactor 1. During the process of stirring and mixing various materials, the viscous mixture adhering to the inner wall of the reactor 1 can be scraped off. like Figure 2 and Figure 3 As shown, the fixed plate 5 is fixedly installed inside the rotating frame 4 and is coaxially arranged with the main shaft 3. Multiple dispersion plates 6 are arranged longitudinally at both ends of the fixed plate 5 to cooperate with the rotation of the main shaft 3 to disperse materials laterally. Multiple dispersion holes 15 are opened on the dispersion plates 6, and there is a gap between two adjacent dispersion plates 6. The main shaft 3 drives the rotating frame 4 to rotate, and the rotating frame 4 drives the multiple dispersion plates 6 to rotate, which can laterally disperse various materials in the reaction vessel 1. The stirring mechanism is set on the fixed plate 5 and is used to fully stir the mixture with the rotation of the main shaft 3. The stirring mechanism includes a rotating shaft 7, a mounting sleeve 8, a stirring paddle 9 and a drive assembly. Multiple rotating shafts 7 are arranged longitudinally on both ends of the fixed plate 5 where the dispersing plate 6 is not set. Multiple mounting sleeves 8 are evenly arranged on the rotating shaft 7 along the axial direction. The mounting sleeves 8 are coaxially fixedly connected to the rotating shaft 7.

The drive assembly includes a drive shaft 10, a driving bevel gear 12, a driven bevel gear 13, and a drive motor 14. A cavity 11 is provided inside the fixed plate 5, and the drive shaft 10 is rotatably mounted within the cavity 11. Multiple driving bevel gears 12 are coaxially fixedly mounted on the drive shaft 10, each driving bevel gear 12 corresponding to two rotating shafts 7 on the same horizontal plane. One end of the driven bevel gear 13 is coaxially fixedly connected to one end of the rotating shaft 7, and the other end meshes with the driving bevel gear 12. The drive motor 14 is mounted on the rotating frame 4, and its output end is coaxially fixedly connected to one end of the drive shaft 10. A protective cover 16 is fixedly mounted on the rotating frame 4, and the drive motor 14 is located inside the protective cover 16, protecting it from damage. The protective cover 16 is located at the bottom of the rotating frame 4 and its cross-sectional area is smaller than that of the bottom of the rotating frame 4 to maintain sealing. Specifically, by starting the drive motor 14, the output end of the drive motor 14 drives the drive shaft 10 to rotate. The drive shaft 10 drives multiple active bevel gears 12 to rotate. The active bevel gears 12 drive two driven bevel gears 13 connected to them to rotate. The driven bevel gears 13 drive the rotating shaft 7 to rotate. The rotating shaft 7 drives multiple mounting sleeves 8 to rotate. The mounting sleeves 8 drive multiple stirring paddles to rotate. This can stir various materials in the reactor 1. In addition, it works with the main shaft 3 to drive the rotating frame 4 to rotate. The rotating frame 4 drives the multiple rotating shafts 7 and stirring paddles to rotate. While the stirring paddle 9 rotates on its own axis, it also revolves around the revolution, which can fully stir and mix the materials. Working Principle: During the saponification process of lutein extract, the continuous saponification device opens the lid and inserts the scraper 19 along the inner wall of the reactor 1. The scraper 19 drives the locking plate 18 into the locking groove 17. Then, the locking bolts 20 are used to lock and fix the locking plate 18 and the rotating frame 4. The lid is then closed, and the reactor 1 operates, intermittently conveying lutein extract and strong alkaline reagent into the reactor. This is achieved by rotating the main shaft 3, simultaneously starting the drive motor 14. The main shaft 3 drives the rotating frame 4 to rotate, which in turn drives multiple dispersing plates 6 to rotate, horizontally dispersing the various materials within the reactor 1. Furthermore, the rotating frame 4 also drives the scraper 19 to rotate. The viscous mixture adhering to the inner wall of the reactor 1 is scraped off. The output end of the drive motor 14 drives the drive shaft 10 to rotate. The drive shaft 10 drives multiple active bevel gears 12 to rotate. The active bevel gears 12 drive two driven bevel gears 13 connected to them to rotate. The driven bevel gears 13 drive the rotating shaft 7 to rotate. The rotating shaft 7 drives multiple mounting sleeves 8 to rotate. The mounting sleeves 8 drive multiple stirring paddles to rotate. This can stir various materials in the reactor 1. In addition, the main shaft 3 drives the rotating frame 4 to rotate. The rotating frame 4 drives the multiple rotating shafts 7 and stirring paddles to rotate. While the stirring paddle 9 rotates on its own axis, it also revolves around the revolution, which can fully stir and mix the materials, resulting in good mixing effect and improved efficiency.
