Description

Technical Field

[0001] The present invention relates to the field of ginsenoside extraction, and particularly to a device and method for removing plasticizers from ginsenoside extracts. Background Art

[0002] Ginsenoside extract is an active ingredient extracted from ginseng, which has various biological activities and pharmacological effects, such as antioxidant, anti-aging, anti-tumor, etc., and is widely used in cosmetics and food. In the raw material transportation and extraction process steps of ginsenosides, this substance of plasticizer is widely used. Therefore, the plasticizer removal treatment is an important step to ensure the safety and health of ginsenoside extracts, in order to avoid potential risks to consumers caused by plasticizer residues. In the existing plasticizer removal treatment process for ginsenoside extracts, it is necessary to successively filter and ion-adsorb the ginsenoside extract solution added with the removal reagent. During the entire plasticizer removal treatment process of the ginsenoside extract solution, it is necessary to transfer between multiple devices and perform corresponding treatment operations successively, which affects the plasticizer removal treatment efficiency of the ginsenoside extract solution. In addition, each device needs to be separately purified and maintained after long-term use, increasing the construction period of the plasticizer removal treatment for the ginsenoside extract solution.

Detailed implementation method

[0017] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0018] Embodiment 1 A plasticizer removal device for a ginsenoside extract, as Figures 1 - 7As shown in the figure, it includes a mounting frame 11, a rotating motor 12, a flipping frame 13, a removal chamber 2, an electric push rod 21, a first filter disc 31, an annular cylinder 32, an adsorption resin block 33, a first compression spring 34, a filtering component, a spline rotating shaft 51 and a waterproof motor 52; Two rotating motors 12 are installed on the mounting frame 11; A flipping frame 13 is fixedly connected between the rotating shafts of the two rotating motors 12; A removal chamber 2 is fixedly connected to the flipping frame 13; A spline rotating shaft 51 is rotatably connected inside the removal chamber 2, and the spline rotating shaft 51 is arranged along the axial direction of the removal chamber 2; A waterproof motor 52 is installed inside the removal chamber 2; The output shaft of the waterproof motor 52 is fixedly connected to the spline rotating shaft 51; An electric push rod 21 is installed on the removal chamber 2, and the electric push rod 21 expands and contracts along the axial direction of the removal chamber 2; Four annular cylinders 32 are connected to the inner wall of the removal chamber 2 at equal intervals along the axial direction. The annular cylinder 32 closest to the outlet end of the removal chamber 2 is fixedly connected to the inner wall of the removal chamber 2, and the other three are movably connected to the inner wall of the removal chamber 2; Except for the annular cylinder 32 closest to the inlet end of the removal chamber 2, each annular cylinder 32 is rotatably connected to a first filter disc 31. The first filter disc 31 has a conical hopper-shaped structure protruding towards the liquid outlet port of the removal chamber 2. The first filter disc 31 is provided with a number of microporous structures that only allow the solution to flow through; The spline rotating shaft 51 is used to drive the first filter disc 31 to rotate; A receiving space is formed between the adjacent first filter discs 31 and the corresponding annular cylinders 32, and the receiving space is filled with adsorption resin blocks 33; The middle part of the annular cylinder 32 is in contact with the inner wall of the removal chamber 2, but the upper extension section and the lower extension section of the annular cylinder 32 are not in contact with the inner wall. Therefore, a circular cavity 320 structure is provided between the upper extension section and the lower extension section of the annular cylinder 32 and the removal chamber 2. The adjacent two annular cylinders 32 are attached to each other through the extension sections, and there is a relative sliding space between the adjacent two annular cylinders 32 to adjust the distance between them, and a waterproof sealing structure is provided at the joint of the adjacent two annular cylinders 32. When the annular cylinder 32 is compressed inside the removal chamber 2, the air in the circular cavity 320 will be compressed, but there will be no great compression resistance to hinder the up and down movement of the annular cylinder 32; A first compression spring 34 is fixedly connected between every two annular cylinders 32, and the first compression spring 34 is sleeved on the outer surface of the annular cylinder 32. The first compression spring 34 is initially in a compressed state, and the first compression spring 34 is located in the circular cavity 320 structure; The area at the inlet end inside the removal chamber 2 is connected with a filtering component, and the filtering component is closer to the inlet end than the first filter disc 31 closest to the inlet end; The filtering component forms a transmission fit with the spline rotating shaft 51; The receiving space between the filtering component and the first filter disc 31 closest to the inlet end is also filled with adsorption resin blocks 33; The telescopic end of the electric push rod 21 is connected to the filtering component; Under the initial condition, the electric push rod 21 is in a downward extended state, so that the adjacent two first filter discs 31 compact the adsorption resin blocks 33 between them tightly, and all the adjacent adsorption resin blocks 33 are in a tightly close state, improving the adsorption and removal treatment efficiency of the adsorption resin blocks 33; A first electric control valve 22 is connected to the liquid inlet port of the removal chamber 2;The liquid outlet port of the removal chamber 2 is connected to a second electric control valve 23.;

[0019] As Figures 4 - 5 shown, except for the first filter disc 31 closest to the liquid outlet port, spiral pressing plates 311 are provided on the convex surfaces of all other first filter discs 31, and the spiral pressing plates 311 are initially buried in the adjacent adsorption resin blocks 33; spines 312 are provided on all the spiral pressing plates 311, and the spines 312 are initially buried in the adjacent adsorption resin blocks 33.

[0020] The removal treatment working steps of the removal device for plasticizers in a ginsenoside extract of the present invention are as follows.

[0021] Add a removal agent to the ginsenoside extract solution, mix the removal agent and the ginsenoside extract solution evenly, let it stand for five hours, and perform a rough filtration treatment on the mixed ginsenoside extract solution to obtain a rough filtrate.

[0022] As Figure 4 shown, when the removal chamber 2 is in the forward vertical state, it is in the removal treatment working mode. The staff connects the interface end of the first electric control valve 22 to the rough filtrate conveying device, and connects the interface end of the second electric control valve 23 to the treatment liquid collection container. The rough filtrate is injected into the removal chamber 2 through the first electric control valve 22 by the externally connected rough filtrate conveying device. The rough filtrate first flows downward through the filter assembly, and the filter assembly performs a fine filtration treatment on the rough filtrate. The fine filter residues carried in the rough filtrate are intercepted by the filter assembly to obtain a fine filtrate. Subsequently, the fine filtrate successively flows downward through each adsorption resin block 33. At this time, all the adsorption resin blocks 33 except the first adsorption resin block 33 in the upper layer are in a state of being compacted by the first filter discs 31 on the upper and lower sides, and the first adsorption resin block 33 in the upper layer is in a state of being compacted by the adjacent first filter disc 31 and the filter assembly. The adsorbed plasticizers in the fine filtrate flowing through are removed by the compacted adsorption resin blocks 33. Finally, the treatment liquid after the removal treatment is collected into the externally connected treatment liquid collection container through the second electric control valve 23. The removal treatment of plasticizers can be completed without transferring the treatment solution between multiple devices, improving the efficiency of removing plasticizers from the ginsenoside extract solution.

[0023] The backwashing treatment working steps of the removal device for plasticizers in a ginsenoside extract of the present invention are as follows.

[0024] As Figure 8As shown, the rotating motor 12 drives the tipping frame 13 and the removal chamber 2 to rotate 180 degrees in the up and down direction, so that the removal chamber 2 is turned to the inverted and upright state. The removal chamber 2 is in the backwashing treatment working mode in the inverted and upright state. The staff connects the interface end of the first electric control valve 22 after flipping to the waste liquid treatment equipment, and connects the interface end of the second electric control valve 23 to the flushing liquid conveying equipment. Then, the electric push rod 21 pulls the filter assembly downward. At this time, all the first compression springs 34 initially in the compressed state start to release elastic potential energy, pushing the annular cylinder 32 connected to it downward. At the same time, the annular cylinder 32 pulls the first filter disc 31 connected to it downward, increasing the space between two adjacent first filter discs 31 up and down, so that the adsorption resin blocks 33 are no longer in the compacted state. At this time, the adsorption resin blocks 33 are stacked on the first filter disc 31 below it in a loose state. Then, the waterproof motor 52 drives the spline rotating shaft 51 to rotate. The spline rotating shaft 51 drives all the first filter discs 31 to rotate. The first filter disc 31 drives the spiral pressing plate 311 and the spines 312 connected to it to rotate. The rotating spiral pressing plate 311 continuously pushes the adsorption resin blocks 33 stacked on the first filter disc 31 upward. At the same time, the spiral pressing plate 311 cooperates with the spines 312 to continuously stir the adsorption resin blocks 33 stacked on the first filter disc 31, improving the looseness of the adsorption resin blocks 33. At the same time, the externally connected flushing liquid conveying equipment continuously conveys flushing liquid into the removal chamber 2 through the second electric control valve 23. The flushing liquid efficiently backwashes the adsorption resin blocks 33 in the loose state. Then, when the flushing liquid continues to flow downward through the filter assembly, the flushing liquid flushes the fine filter residues intercepted in the filter assembly downward. Finally, the waste liquid formed by flushing is discharged into the externally connected waste liquid treatment equipment through the first electric control valve 22.

[0025] Embodiment 2 The difference between this embodiment and Embodiment 1 is that, as Figures 1 - 7As shown in the figure, the filtering component includes an annular cover 41, a second filter disc 42, a fine filter screen 43 and a filter column 44; the second filter disc 42 is movably fitted on the spline rotating shaft 51. The second filter disc 42 has the same shape and the same orientation as the first filter disc 31. The second filter disc 42 is provided with a number of microporous structures that only allow the solution to flow through. In the initial state, the lower side of the second filter disc 42 is closely attached to the adjacent adsorption resin block 33; the annular cover 41 is rotatably connected to the second filter disc 42. The annular cover 41 is penetrated by the spline rotating shaft 51 and they do not contact each other. The annular cover 41 is movably connected to the inner wall of the removal chamber 2, and a sealing ring is provided between them; the fine filter screen 43 is fixedly connected to the annular cover 41; a receiving space is formed between the annular cover 41, the fine filter screen 43 and the second filter disc 42, and they jointly accommodate the filter column 44; the telescopic end of the electric push rod 21 is fixedly connected to the annular cover 41; the convex surface of the second filter disc 42 is also provided with a spiral pressing plate 311; the spiral pressing plate 311 on the second filter disc 42 is also provided with a number of spikes 312; the annular cover 41 is slidably connected to the annular cylinder 32 closest to the inlet end in the removal chamber 2; a second compression spring 45 is fixedly connected between the annular cover 41 and the annular cylinder 32 closest to the inlet end in the removal chamber 2, and the second compression spring 45 is sleeved on the outer surface of the annular cover 41. The second compression spring 45 is in a compressed state initially; the filter column 44 is an elastic folded columnar structure composed of a number of fine filter screens stacked together. The fine filter screens are made of an elastic foam metal structure. In the initial state, the annular cover 41 compresses all the fine filter screens forming the filter column 44 downward toward the annular cylinder 32, so that the gaps between all the fine filter screens are compressed.

[0026] In the removal processing working mode, as Figure 4 shown, the removal chamber 2 is in a positive vertical state. The electric push rod 21 extends, pushing the annular cover 41 to move downward to the limit position. All the fine filter screens in the filter column 44 are in a compressed state. At this time, the rough filtrate entering the removal chamber 2 from top to bottom flows through the fine filter screen 43 and the filter column 44 in sequence. The fine filter residues carried in the rough filtrate are intercepted at the gaps between all the fine filter screens. The fine filter screen 43 and all the tightly compressed fine filter screens in the filter column 44 jointly perform fine filtration on the rough filtrate. The obtained fine filtrate then passes downward through the second filter disc 42 and flows through each adsorption resin block 33 in sequence for adsorption and removal processing. During this process, the first filter disc 31 and the second filter disc 42 can not only separate two adjacent adsorption resin blocks 33, but also allow the fine filtrate to flow downward smoothly.

[0027] In the backwashing processing working mode, as Figure 8As shown, the removal chamber 2 is in an inverted and upright state. During the process that the telescopic end of the electric push rod 21 contracts and pulls the annular cover 41 to drive the entire filter assembly to move downward, the second compression spring 45 initially in a compressed state releases its elasticity to push the annular cylinder 32 closest to the inlet end to drive the second filter disc 42 to move away from the fine filter screen 43. At this time, the space between the fine filter screen 43 and the second filter disc 42 increases, allowing all the fine filter screens compressed in the filter column 44 to expand in the up and down directions, increasing the gaps between all the fine filter screens. At this time, the flushing liquid entering the removal chamber 2 from top to bottom flows through each fine filter screen successively, performing a reverse flushing process on the fine filter screens. Since the gaps between all the fine filter screens are increased, the fine filter residues intercepted at the gaps between all the fine filter screens can be more efficiently flushed downward by the flushing liquid, improving the reverse flushing effect on all the fine filter screens in the filter column 44.

[0028] Example 3 The difference between this embodiment and Embodiment 1 is that the enzymatic hydrolysate is prepared by mixing lipase and phospholipase. Lipase and phospholipase can efficiently catalyze the hydrolysis reactions of fats and phospholipids. Lipase can decompose triglycerides into glycerol, fatty acids, and glycerol monoesters, while phospholipase can specifically hydrolyze the ester bonds in phospholipid molecules to generate lysophospholipids, free fatty acids, and other products. This efficient catalytic effect makes it have significant application value as an enzymatic hydrolysate in industrial and food processing.

[0029] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
