Description

Technical Field

[0001] This utility model relates to the technical field of anthocyanin extraction equipment, specifically to anthocyanin molecular-level extraction equipment. Background Technology

[0002] Anthocyanins have antioxidant and free radical scavenging functions, anti-mutagenic functions, and are widely used as natural additives in food production. Red raspberry anthocyanins are extracted from red raspberries and have high nutritional value.

[0003] Patent application CN108003128B discloses a method for extracting proanthocyanidins from grape seeds. This invention overcomes the difficulties in dissolving proanthocyanidins from grape seed coats and the high degree of polymerization of proanthocyanidins in the extract. It uses *Aspergillus niger* as the inoculum to ferment grape seeds, utilizing enzymes such as cellulase and pectinase produced by *Aspergillus niger* to degrade the grape seed coat, facilitating the dissolution of proanthocyanidins. Different volume fractions of ethanol are used as the eluent to elute macroporous adsorption resin, fractionating the proanthocyanidins. Then, partial acid hydrolysis is performed to increase the content of oligomeric proanthocyanidins in the extract. The extract obtained by this invention contains ≥98% oligomeric proanthocyanidins, with an average degree of polymerization between 2.5 and 3.0, making it easily absorbed in vivo and exhibiting strong antioxidant activity.

[0004] However, the current technology for extracting anthocyanins through multiple steps is inefficient and cannot meet the application requirements. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an anthocyanin molecular-level extraction device, which can effectively solve the problems in the existing technology.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] This utility model provides an anthocyanin molecular-level extraction device, including a material cylinder, a cylinder cover, and a drive motor disposed at the top of the cylinder cover. A filter plate is fixed to the bottom end of the cylinder cover, and a rotating shaft is fixed to the middle of the top end of the filter plate. The outer side of the bottom end of the rotating shaft is fixedly connected to the inner side of the ramp plate. The top end of the rotating shaft is fixedly connected to a square shaft, and the top end of the square shaft is fixedly connected to the output end of the drive motor. A connecting cylinder is sleeved on the outer side of the rotating shaft, and a pressure roller is fixed between the connecting cylinder and the cylinder cover.

[0010] Furthermore, a filter disc is provided inside the material cylinder, and a hopper is fixed to the bottom end of the filter disc. The outer side of the connecting cylinder is fixedly connected to the inner side wall of the cylinder cover through a connecting rod.

[0011] Furthermore, a square shaft is fixed to both the drive motor end and the rotating shaft end, and bolts are fixed between the two sets of square shafts. A connecting piece is sleeved between the upper and lower sets of bolts, and the connecting piece is a hollow iron piece.

[0012] Furthermore, a spring is sleeved on the outer side of the rotating shaft. The spring is movably arranged inside the connecting cylinder and is not fixed to the structure that contacts the upper and lower ends. There is a gap between the top end of the connecting cylinder and the bottom end of the rotating shaft.

[0013] Furthermore, multiple sets of ramp plates are arranged equidistantly on the top of the filter plate, and the ramp plate is half of a trumpet-shaped structure with a large outer diameter and a small inner diameter.

[0014] Furthermore, a vertical circular groove is provided on the side wall of the cylinder cover, and the outer side of the pressure roller is sleeved in the circular groove.

[0015] Furthermore, a feed inlet is fixed on the side wall of the cylinder cover.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0018] This invention transmits power via a drive motor, a square shaft, a rotating shaft, and a ramp plate. After material is fed in through the feed inlet on one side, the ramp plate rotates via the rotating shaft. During rotation, the material is crushed by the pressure roller upon contact with it. The ramp plate will shift upwards / downwards due to the material's compression. This is buffered by a spring structure, and the square shaft moves within the connecting plate for adjustment. There is a gap between the two sets of square shafts to accommodate the displacement transmitted from the ramp plate. Due to the difference in the inner and outer diameters of the pressure roller, the outer side of the pressure roller is fitted into a circular groove, allowing for vertical movement. During rotation, the pressure roller-connecting cylinder-connecting rod remain in the same position. There is a gap between the bottom of the connecting cylinder and the bottom of the rotating shaft, so it does not affect the lifting / lowering and rotation functions of the rotating shaft. Therefore, during use, this device can fully crush and press materials through the combination structure of multiple sets of ramps and pressure rollers to extract raw material juice, which facilitates the subsequent extraction of anthocyanins and serves as a preliminary treatment function. Compared with existing structures, this device has the functions of multiple pressing, extended crushing time and path, thereby improving the crushing effect. Attached Figure Description

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example: Anthocyanin molecular-level extraction equipment, see attached document. Figure 1 -Appendix Figure 5The device includes a material cylinder 1, a cylinder cover 2, and a drive motor 3 disposed at the top of the cylinder cover 2. A filter plate 5 is fixed to the bottom end of the cylinder cover 2. A rotating shaft 33 is fixed to the middle of the top end of the filter plate 5. The outer side of the bottom end of the rotating shaft 33 is fixedly connected to the inner side of the ramp plate 6. The top end of the rotating shaft 33 is fixedly connected to a square shaft 31. The top end of the square shaft 31 is fixedly connected to the output end of the drive motor 3. A connecting cylinder 61 is sleeved on the outer side of the rotating shaft 33. A pressure roller 51 is fixed between the connecting cylinder 61 and the cylinder cover 2.

[0029] The material cylinder 1 is equipped with a filter disc 11 inside, and a hopper 12 is fixed to the bottom end of the filter disc 11. The outer side of the connecting cylinder 61 is fixedly connected to the inner side wall of the cylinder cover 2 via a connecting rod 36. A square shaft 31 is fixed to both the drive motor 3 and the rotating shaft 33. Bolts 34 are fixed between the two sets of square shafts 31, and connecting pieces 35 are sleeved between the upper and lower sets of bolts 34. The connecting pieces 35 are hollow iron parts. Power is transmitted through the drive motor 3-square shaft 31-rotating shaft 33-ramp plate 6, and the material passes through one side. After the material is fed into the feed inlet 4, the ramp plate 6 rotates via the rotating shaft 33. During the rotation, when it comes into contact with the pressure roller 51, the material can be crushed by the pressure roller 51. The ramp plate 6 will move up / down due to the extrusion of the material. At this time, it can be stretched by the spring 32 structure for buffering, and the square shaft 31 can be moved within the connecting piece 35 for adaptation and adjustment. There is a gap between the two sets of square shafts 31 to accommodate the displacement transmitted from the ramp plate 6. Due to the wheel difference between the inner and outer diameters of the pressure roller 51, the outer side of the pressure roller 51 is fitted into the circular groove and can move up and down.

[0030] A spring 32 is sleeved on the outer side of the rotating shaft 33. The spring 32 is movably arranged inside the connecting cylinder 61 and is not fixed to the structure at the upper and lower ends. There is a gap between the top end of the connecting cylinder 61 and the bottom end of the rotating shaft 33. Multiple sets of ramp plates 6 are arranged equidistantly on the top of the filter plate 5. The ramp plate 6 is half of a trumpet-shaped structure with a large outer diameter and a small inner diameter. A vertical circular groove is opened on the side wall of the cylinder cover 2, and the outer side of the pressure roller 51 is sleeved in the circular groove. A feed inlet 4 is fixed on the side wall of the cylinder cover 2. During rotation, the pressure roller 51... -Connecting cylinder 61- Connecting rod 36 remains in the same position. There is a gap between the bottom of connecting cylinder 61 and the bottom of rotating shaft 33, so it will not affect the lifting / lowering and rotation functions of rotating shaft 33. Therefore, during use, this device can fully crush and press materials through the combination structure of multiple sets of ramp plates 6 and pressure rollers 51 to extract raw material juice, which is convenient for subsequent anthocyanin extraction and plays a preliminary processing function. Compared with the existing structure, this device has the functions of multiple pressing, extended crushing time and path, thereby improving the crushing effect.
