Description

Technical Field

[0001] This utility model relates to the field of temperature-controlled dissolution technology of ferulic acid, and in particular to a recrystallization device for producing ferulic acid. Background Technology

[0002] Ferulic acid, a natural phenolic acid compound widely used in pharmaceuticals, food, and cosmetics, directly affects the efficacy and safety of these products due to its purity. Recrystallization is a key process for improving the purity of ferulic acid. The core principle is to utilize the difference in solubility of ferulic acid at different temperatures, removing impurities through steps such as dissolution, filtration, crystallization, and separation.

[0003] In traditional equipment, the dissolving and crystallizing chambers are often independently temperature-controlled. When the high-temperature solution after dissolution enters the crystallizing chamber, a drastic temperature difference often occurs due to the initial low temperature of the crystallizing chamber, causing localized instantaneous supersaturation of the solution. This results in the formation of a large number of fine crystals that encapsulate impurities, ultimately reducing the purity of the final product. Furthermore, subsequent crystallization processes are relatively simple and have poor overall performance.

[0004] Therefore, it is necessary to provide a recrystallization apparatus for producing ferulic acid to solve the above-mentioned technical problems. Utility Model Content

[0014] This invention provides a recrystallization apparatus for producing ferulic acid. To improve the overall efficiency of the apparatus during the dissolution and crystallization process, a flow-guiding temperature control component is incorporated to link the temperatures of the dissolution and crystallization stages. This prevents large internal temperature fluctuations that could lead to localized uneven saturation, thereby improving crystal uniformity and purity.

The cover plate structure 25 is used for inspecting the internal structure of the reaction substrate 21.

[0025] During the reaction operation, the feed guide 23 and discharge control 24 installed on the inner wall of the reaction assembly 2 can assist in the feeding and discharging of materials, improving the ease of use of the structure.

[0026] The reaction component 2 includes, but is not limited to, vessel-type and tank-type; in this embodiment, the reaction component 2 is preferably vessel-type.

A flow guiding circulation structure 35 is installed at the output end of the circulation structure 34. The flow guiding circulation structure 35 is used for temperature control and adjustment of the material on the inner wall of the reaction component 2.

[0028] To reduce temperature differences during transport, the circulation structure 34 at both ends continuously circulates the liquid inside the heating component 31 and the cooling component 32 to ensure a suitable internal temperature for the reaction component 2.

[0029] Among them, the flow guiding temperature control component 3 includes, but is not limited to, sleeve type and coil type; in this embodiment, the flow guiding temperature control component 3 is preferably coil type.

[0030] The driving crushing component 4 includes a driving structure 41, a driving rod 42 is installed at the output end of the driving structure 41, a driving ring 43 is installed on the inner wall of the driving rod 42, and a crushing and stirring structure 44 is installed on the side end of the driving ring 43.

[0031] When the substance is added into the reaction assembly 2, the top drive structure 41 drives the workpiece drive of the crushing and stirring structure 44 to pre-crush and stir the added substance, thereby facilitating the next process.

[0032] The driving crushing component 4 includes, but is not limited to, motor-driven and hydraulically driven types; in this embodiment, the driving crushing component 4 is preferably motor-driven.

[0033] The driven scraping assembly 5 includes a rotating ring 51 and a rotating frame 53. An extension support structure 52 is installed on the inner wall of the rotating ring 51.

An elastic support member 56 is installed on the side end of the rotating frame 53. The elastic support member 56 is used for the elastic support of the rotating frame 53.

[0034] When scraping off the internal crystals, the extended support structures 52 at both ends will rotate under the structural control of the active control component 7. Then, the flexible scraping structure 54 at the side end will scrape off the crystals on the inner wall in a flexible manner, and the elastic support 56 at the side end will provide elastic support for the flexible scraping structure 54 to reduce crystal breakage caused by rigid contact.

[0037] When the driven scraping component 5 rotates, the guide frame structure 61 and guide block structure 62 set at both ends can restrict the elastic structure and prevent structural deviation during rotation.

The active component 74, in conjunction with the transmission component 71, can be used to drive the structure of the driven scraping component 5.

[0040] When the driven scraping component 5 is driven, the push rod structure 73 at the side end is controlled by the signal of the controller to push the active component 74 at the side end, which in turn makes the active component 74 contact the inner wall of the transmission component 71. Then, under the structural drive of the driving crushing component 4, the driven scraping component 5 is synchronously driven to rotate synchronously, so as to facilitate the flexible scraping of crystals on the inner wall.

[0041] The active control component 7 includes, but is not limited to, pneumatic and electric actuator types; in this embodiment, the active control component 7 is preferably an electric actuator type.

[0042] The working principle of the recrystallization apparatus for producing ferulic acid provided by this utility model is as follows:

[0043] When a substance is dissolved and crystallized, the device first adds the substance to the reaction assembly 2 and pre-crushes and stirs it using the top-mounted drive crushing assembly 4 to reduce dissolution time. Then, the stirring and crushing stop, and internal impurities are filtered through an external filter structure. The drive crushing component is disassembled to prevent crystal breakage during later scraping. After manual filtration, the substance crystallizes directly inside the reaction assembly 2. At the same time, the flow-guiding temperature control assembly 3 at both ends controls the temperature difference inside the reaction assembly 2 to prevent overheating or overcooling. After the internal substance has crystallized, the top-mounted active control assembly 7 clamps the structure to the inner wall of the drive crushing assembly 4. Then, the top-mounted drive crushing assembly 4 drives the structure, and simultaneously drives the driven scraping assembly 5 to flexibly scrape the crystals off the inner wall of the reaction assembly 2.

[0044] Compared with related technologies, the recrystallization apparatus for producing ferulic acid provided by this utility model has the following beneficial effects:

[0045] To improve the overall efficiency of the device during the dissolution and crystallization process, a flow-guiding temperature control component 3 is installed to link the temperatures of the dissolution and crystallization stages. This prevents large internal temperature fluctuations that could lead to uneven saturation, thereby improving crystal uniformity and purity. Simultaneously, after crystallization, the driven scraping component 5, in conjunction with the active control component 7, automatically drives the driven scraping component 5 under the structural positioning of the active control component 7. This transmits the driving force of the driving crushing component 4 to the scraping component, facilitating the gentle scraping of internal crystals. Stirring also breaks down the boundary layer on the crystal surface, reducing the adhesion between the crystals and the container walls.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
