Description

Technical Field

[0001] This utility model relates to the field of ascorbic acid separation technology, and more specifically, to an ascorbic acid separation and purification device. Background Technology

[0002] Currently, astaxanthin is the main active ingredient in cashew nut shell oil (CNSL), possessing antibacterial and antioxidant properties. However, its separation process faces two major challenges: stability issues—astaxanthin in unheated cashew nut shell oil is easily decarboxylated to cashew phenol, requiring acid treatment to inhibit the decarboxylation reaction (e.g., adding phosphoric acid or sulfuric acid, pH ≤ 4.5); and low separation efficiency—traditional solvent extraction methods suffer from incomplete solid-liquid separation, high solvent residue, and high energy consumption. While existing technologies involve cashew nut shell kernel separation devices, they do not optimize the process chain for astaxanthin extraction; although acid precipitation methods have been proposed to improve yield, the design of supporting equipment is lacking. Utility Model Content

[0003] The purpose of this invention is to provide a device for separating and purifying lacquer acid, which integrates pretreatment, acid stabilization, and high-efficiency separation functions, and can effectively solve the problems of oxidation inactivation, decarboxylation, and low solid-liquid separation efficiency during the extraction of lacquer acid.

[0032] Please refer to Figures 1 to 4 The lacquer acid separation and purification device provided in this embodiment includes a main body 1, which can be a rigid tank structure. The main body 1 has a crushing chamber 11 inside, and an inlet 13 at its upper end. The inlet 13 allows cashew shells to be poured into the crushing chamber 11. The inlet 13 is provided with an openable and closable cover 14. The cover 14 is, for example, hinged to the main body 1. Alternatively, the cover 14 can be a sliding cover or a screw-on cover (e.g.,...). Figure 2 As shown), the cover 14 can be opened to pour cashew shells into the crushing chamber 11.

[0033] The astragalus acid separation and purification device also includes a crushing module 12, which is located inside the crushing chamber 11, specifically at the bottom of the main body 1. In order to guide the crushed material to a predetermined area and facilitate the execution of the next process, in this embodiment, the bottom end of the crushing chamber 11 of the main body 1 can be set as an inclined surface. The crushing module 12 is located on the inclined surface. The crushing module 12 includes a high-speed rotating three-dimensional cyclone blade. After the three-dimensional cyclone blade rotates at high speed, it crushes the cashew shells in the crushing chamber 11 to form pre-treated powder. These pre-treated powders converge at the conveying port along the inclined surface.

[0034] The lacquer acid separation and purification device also includes a nitrogen supply module 2, which is used to supply nitrogen to the crushing chamber 11. Maintaining the crushing chamber 11 in a nitrogen environment can effectively prevent the crushed material from being oxidized.

[0035] The ascorbic acid separation and purification device also includes a screw conveyor 3, which is located at the conveying port of the crushing module 12. The screw conveyor 3 is used to convey the pretreated powder to the extraction container 4. The screw conveyor 3 includes a main shaft 31 and screw blades 32. A baffle 33 is also provided on one side of the main shaft 31. The baffle 33 extends from below the feed port of the screw conveyor 3, partially blocking the feed port to prevent the material from directly impacting the screw blades 32. The material is discharged from the discharge port to the next process.

[0036] The extraction container 4 is also equipped with an extraction solvent addition module 41, through which the aforementioned material is discharged from the outlet into the extraction container 4. The extraction solvent addition module 41 is used to add extraction solvent to the extraction container 4, so that the pretreated powder is mixed with the extraction solvent to form a solid-liquid mixture. To improve the extraction effect, a vibration module for vibrating the extraction container 4 can be provided. This vibration module can be, for example, an ultrasonic vibration module 42, located at the bottom of the extraction container 4, which improves the extraction efficiency through ultrasonic vibration.

[0037] The ascorbic acid separation and purification device also includes a centrifugal separation device 6, an acid treatment reactor 7, a multi-stage settling tank 8, and a drying system 9.

The centrifugal separation device 6 is connected to the acid treatment reactor 7 via a second conveying pipe 52. The acid treatment reactor 7 is connected to the multi-stage settling tank 8 via a third conveying pipe 53. The multi-stage settling tank 8 is connected to the drying system 9 via a fourth conveying pipe 54. It is important to note that the first conveying pipe 51, the second conveying pipe 52, the third conveying pipe 53, and the fourth conveying pipe 54 are all equipped with control valves for controlling the material flow rate, specifically solenoid valves, thereby enabling precise control of material transmission.

[0038] The centrifugal separation device 6 includes a horizontal screw centrifuge, which is used to separate the solid-liquid mixture.

[0039] The acid treatment reactor 7 is used to add acid to the liquid after solid-liquid separation. This acid is a common acid in this field.

[0040] The acid treatment reactor 7 is equipped with an online pH monitor 71 and an automatic acid addition system 72. The automatic acid addition system 72 can maintain a stable pH value and inhibit the decarboxylation of lacquer acid.

[0041] The multi-stage settling tank 8 has a membrane separation system, through which lipid-soluble impurities in the acidified liquid are removed to form a precursor liquid, which is a liquid close to the final product.

[0042] The drying system 9 includes a vacuum belt dryer, a highly efficient vacuum drying device. This equipment utilizes a novel non-stick belt material, multi-stage temperature control, automatic vacuum adjustment, and a novel structure, featuring low energy consumption and minimal loss of volatile components. It can be used for drying solid or liquid materials. The precursor liquid is vacuum-dried using this belt dryer to obtain the final product, which retains the activity of lacquer resin acid.

[0043] The ascorbic acid separation and purification device provided in this embodiment integrates pretreatment, acid stabilization, and high-efficiency separation functions through the coordinated action of various modules. In particular, the nitrogen supply module 2 can solve the problem of oxidation and deactivation during the ascorbic acid extraction process. Combined with the screw conveyor 3, extraction solvent addition module 41, ultrasonic vibration module 42, centrifugal separation device 6, acid treatment reactor 7, multi-stage settling tank 8, and drying system 9, it can effectively solve the problems of low decarboxylation and solid-liquid separation efficiency.
