Description

Technical Field

[0001] This utility model relates to the field of marigold extract production technology, and in particular to an extraction device for marigold extract production. Background Technology

[0002] Marigolds are annual herbaceous plants belonging to the genus Marigold in the family Asteraceae. Lutein is an important antioxidant, which is mainly found in marigolds. The extraction of lutein from marigolds requires multiple steps, among which leaching is an important step. Leaching refers to the process of extracting soluble substances from solids using chemical solvents.

[0003] Existing leaching devices typically mix the leachate directly with the raw material. This requires the mixture to be filtered after leaching, increasing the workflow and reducing efficiency. Furthermore, marigold raw materials absorb and retain a large amount of leachate, and failing to discharge this leachate leads to waste and hinders rapid separation between the raw material and the leachate. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide an leaching device for marigold extract production, so as to solve the technical problem that existing leaching devices usually mix the leachate and raw materials directly together, which is not conducive to the rapid separation between the raw materials and the leachate.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An leaching device for producing marigold extract includes an leaching cylinder with a discharge pipe at the bottom, a cylinder cover installed at the open top of the leaching cylinder, an electric heating wire installed on the outer edge of the inside of the leaching cylinder, and a mesh cylinder rotatably installed at the center inside the leaching cylinder, with the mesh cylinder inside the inner hole of the electric heating wire.

[0008] A mesh pressure plate is provided on the upper side of the inside of the mesh cylinder. Two electric telescopic rods are symmetrically installed on the top of the cylinder cover, and the movable end of the electric telescopic rod is located inside the cylinder cover and connected to the top of the mesh pressure plate.

[0009] A transducer is fixed at the center of the top of the cylinder cover, and a vibration rod is fixed at one end of the transducer near the cylinder cover. An ultrasonic generator is installed on the top of the cylinder cover.

[0010] As an improved technical solution, stirring rods are fixed on all four sides of each joint of the vibrating rod, and grooves for the stirring rods to pass through are opened on the mesh pressure plate and directly above the four stirring rods.

[0011] As an improved technical solution, a row of cutting cavities is provided on the stirring rod, and a cutter is fixed in the middle of the cutting cavity.

[0012] As an improved technical solution, filter cloth two is fixed on the inner wall surface of the mesh cylinder, and filter cloth one is fixed on the bottom of the mesh pressure plate.

[0013] As an improved technical solution, a drive motor is fixed at the center of the bottom of the leaching cylinder, and a locking block coaxial with the leaching cylinder is fixedly installed at the drive end of the drive motor. A locking seat coaxial with the mesh cylinder is fixed at the center of the bottom of the mesh cylinder, and a locking groove for engaging with the locking block is opened at the bottom of the locking seat.

[0014] As an improved technical solution, a ring of universal ball bearings is fixed at the outer edge of the bottom of the mesh cylinder, and the rolling end of the universal ball bearings is in contact with the bottom of the inner wall of the leaching cylinder.

[0015] As an improved technical solution, the ends of the mesh cylinder away from the card seat are connected by lifting rings, and U-shaped frames are welded to both sides of the top of the cylinder cover.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the ultrasonic generator uses a transducer to make the vibrating rod vibrate at a high frequency. The vibration of the vibrating rod inside the mesh cylinder can quickly break the cell wall, accelerate the release of effective ingredients in the cell, thereby increasing the contact area between the effective ingredients and the solvent and improving the dissolution rate.

[0018] 2. In this utility model, the mesh cylinder rotates with the drive motor. When the mesh cylinder rotates, the raw material inside it collides with the stirring rod, thus agitating the raw material inside the mesh cylinder through the stirring rod. This prevents the raw material from settling, increases the contact area between the raw material and the solvent, and promotes the mixing effect of the leachate. This is beneficial to promoting the leaching effect and leaching efficiency of the raw material. The leaching is assisted by both stirring and ultrasound, which can greatly shorten the extraction time and improve the extraction rate.

[0019] 3. In this utility model, the raw materials are all located inside the mesh cylinder, while the leachate is dispersed inside the leachating cylinder. When the leachate is discharged, the raw materials and the leachate are separated, which simplifies the workflow and improves work efficiency. At the same time, the mesh pressure plate presses all the raw materials inside the mesh cylinder, thereby squeezing out the leachate remaining in the raw materials and avoiding the situation of incomplete discharge and waste of leachate. Furthermore, the mesh cylinder can be directly pulled out from the inside of the leachating cylinder to remove the residue from the inside of the leachating cylinder, which facilitates the cleaning of the inside of the leachating cylinder.

[0031] like Figures 1 to 4 As shown in the figure, this embodiment provides an leaching device for marigold extract production. This leaching device for marigold extract production includes an leaching cylinder 1 with a discharge pipe at the bottom. Three support legs are welded to the bottom of the leaching cylinder 1. A cylinder cover 2 is installed at the open top of the leaching cylinder 1. The leaching cylinder 1 and the cylinder cover 2 are detachably fixedly connected by a flange. An electric heating wire 11 is installed on the outer edge of the inside of the leaching cylinder 1. A mesh cylinder 5 is rotatably installed at the center of the inside of the leaching cylinder 1, and the mesh cylinder 5 is in the inner hole of the electric heating wire 11.

[0032] A mesh pressure plate 4 is provided on the upper side of the inside of the mesh cylinder 5. Two electric telescopic rods 43 are symmetrically installed on the top of the cylinder cover 2. The movable end of the electric telescopic rod 43 is located inside the cylinder cover 2 and connected to the top of the mesh pressure plate 4. The electric telescopic rod 43 extends to drive the mesh pressure plate 4 to extend into the inside of the mesh cylinder 5. When the mesh pressure plate 4 enters the inside of the mesh cylinder 5, it presses down the raw material on the inner wall of the mesh cylinder 5, and finally presses all the raw material into the inside of the mesh cylinder 5, thereby squeezing out the leachate remaining in the raw material and avoiding the situation of incomplete leachate discharge and waste.

[0033] A transducer 3 is fixed at the center of the top of the cylinder cover 2. A vibrating rod 32 is fixed at one end of the transducer 3 near the cylinder cover 2. Both the cylinder cover 2 and the mesh pressure plate 4 have circular holes at their centers for the vibrating rod 32 to pass through. An ultrasonic generator 31 is installed on the top of the cylinder cover 2. An ultrasonic wire is installed between the output end of the ultrasonic generator 31 and the input end of the transducer 3. The ultrasonic generator 31 causes the vibrating rod 32 to vibrate at a high frequency through the transducer 3. The vibration of the vibrating rod 32 inside the mesh cylinder 5 can quickly break the cell wall, accelerate the release of effective ingredients in the cells, thereby increasing the contact area between the effective ingredients and the solvent and improving the dissolution rate.

[0034] After leaching is completed, the drive motor 54 is turned off, and the leachate inside the leaching cylinder 1 is discharged through the discharge pipe on the leaching cylinder 1. The raw materials are all located inside the mesh cylinder 5, while the leachate is dispersed inside the leaching cylinder 1. When the leachate is discharged, the raw materials and the leachate are separated, which simplifies the workflow and improves work efficiency. At the same time, the residue can be removed directly from the inside of the leaching cylinder 1 by pulling the mesh cylinder 5 out directly, which facilitates cleaning of the inside of the leaching cylinder 1.

[0035] like Figures 1 to 3 As shown in the figure, in this embodiment, stirring rods 33 are fixed on all four sides of each joint of the vibrating rod 32, and grooves 42 for the stirring rods 33 to pass through are provided on the mesh pressure plate 4 and directly above the four stirring rods 33.

[0036] like Figures 2 to 3 As shown in the figure, in this embodiment, a row of cutting cavities 34 is provided on the stirring rod 33. A cutter 35 is fixed in the middle of the inside of the cutting cavity 34, and both ends of the cutter 35 are blade ends. When the raw material comes into contact with the stirring rod 33, some of the raw material will pass through the inside of the cutting cavity 34 and come into contact with the cutter 35. The cutter 35 further crushes the raw material, thereby helping to improve the leaching of the raw material.

[0037] like Figures 1 to 4 As shown in the figure, in this embodiment, filter cloth 2 51 is fixed on the inner wall of the mesh cylinder 5, and filter cloth 1 41 is fixed on the bottom of the mesh pressure plate 4. The arrangement of filter cloth 2 51 and filter cloth 1 41 ensures the filtration effect of the filtrate.

[0038] like Figures 2 to 4 As shown in the figure, in this embodiment, a drive motor 54 is fixed at the center of the bottom of the leaching cylinder 1, and the drive end of the drive motor 54 is located inside the leaching cylinder 1. A locking block 55 coaxial with the leaching cylinder 1 is fixedly installed at the drive end of the drive motor 54. A locking seat 52 coaxial with the mesh cylinder 5 is fixed at the center of the bottom of the mesh cylinder 5. A locking groove 53 is opened at the bottom of the locking seat 52 to engage with the locking block 55. The mesh cylinder 5 rotates with the drive motor 54. When the mesh cylinder 5 rotates, the raw material inside it collides with the stirring rod 33. This achieves the stirring of the raw material inside the mesh cylinder 5 by the stirring rod 33, avoiding the sedimentation of the raw material, increasing the contact area of ​​the raw material and solvent, promoting the mixing effect of the leachate, and improving the leaching effect and leaching efficiency of the raw material. The leaching is assisted by both stirring and ultrasound, which can greatly shorten the extraction time and improve the extraction rate.

[0039] like Figure 4 As shown, in this embodiment, a ring of universal ball bearings 56 is fixed at the outer edge of the bottom of the mesh cylinder 5, and the rolling end of the universal ball bearings 56 is in contact with the bottom of the inner wall of the leaching cylinder 1. The universal ball bearings 56 play a role in forming the mesh cylinder 5 and ensuring the stability of the mesh cylinder 5 when rotating.

[0040] like Figures 1 to 2 As shown in the figure, in this embodiment, the ends of the mesh cylinder 5 away from the card seat 52 are connected by hanging rings, and the top of the cylinder cover 2 is welded with U-shaped frames 21 on both sides.

[0041] In use, the two U-shaped frames 21 are hung by a crane to lift the cylinder cover 2 upward and separate it from the leaching cylinder 1. Then, the mesh cylinder 5 is placed inside the leaching cylinder 1 and the locking block 55 and the locking groove 53 are engaged. The raw material is placed inside the mesh cylinder 5. After the raw material is placed, the crane lowers the cylinder cover 2 so that the cylinder cover 2 is closed on the top of the leaching cylinder 1.

[0042] At this time, the electric heating wire 11 is turned on to heat the liquid inside the leaching cylinder 1, promoting the leaching of the raw materials. At the same time, the ultrasonic generator 31 causes the vibrating rod 32 to vibrate at a high frequency through the transducer 3. The vibration of the vibrating rod 32 inside the mesh cylinder 5 can quickly break the cell wall and improve the dissolution rate.

[0043] The drive motor 54 drives the card block 55 to rotate. Under the card block 55 and the card seat 52, the mesh cylinder 5 rotates with the drive motor 54. When the mesh cylinder 5 rotates, the raw material inside it collides with the stirring rod 33. The stirring rod 33 agitates the raw material inside the mesh cylinder 5. The leaching is assisted by both stirring and ultrasound, which can greatly shorten the extraction time and improve the extraction rate.

[0044] After leaching is completed, the drive motor 54 is turned off, and the leachate inside the leaching cylinder 1 is discharged through the discharge pipe on the leaching cylinder 1. The raw materials are all located inside the mesh cylinder 5, while the leachate is dispersed inside the leaching cylinder 1. When the leachate is discharged, the separation between the raw materials and the leachate is achieved.

[0045] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
