[0026] As shown in the figure, in order to clearly implement the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for schematic needs and is not intended to limit the present invention to this specific structure, device, and environment. According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments, and the adjustments or modifications still fall within the scope of the appended claims. Detailed implementation manners
[0027] The following will describe in detail a device for extracting shell pigment from oil-tea camellia fruits provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.
[0028] As Figure 1 and Figure 3 shown, an embodiment of the present invention provides a device for extracting shell pigment from oil-tea camellia fruits, including: an extraction tank 1; a driving frame 2 provided on the top of the extraction tank 1; a stepping motor 3 provided on the top of the driving frame 2; a rotating rod 6 provided in the extraction tank 1, and the top of the rotating rod 6 penetrates through the driving frame 2 and is connected to the stepping motor 3; a first spiral blade 5 provided at the center of the rotating rod 6; two rotating rods 9 provided in the extraction tank 1 and located on both sides of the rotating rod 6; two second spiral blades 8 respectively provided on the two rotating rods 9; a stirring blade 7 provided at the bottom of the rotating rod 6 and in sliding contact with the bottom wall of the inner cavity of the extraction tank 1.
[0029] By providing the stepping motor 3, the output end of the stepping motor 3 is fixed to the rotating rod 6. When the stepping motor 3 works through an external current, the output end of the stepping motor 3 generates a rotational force, driving the rotating rod 6 to move synchronously, providing a power source for the rotation of the rotating rod 6; by providing the first spiral blade 5 and the second spiral blade 8 with opposite rotation directions to form a reverse flow, it promotes the full mixing of the fragments and the solution.
[0030] As Figure 3 shown, it further includes: one side of the stirring blade 7 is inclined upward. By providing the stirring blade 7, the upward inclination of the blade can more effectively push the oil-tea camellia fruit shell fragments upward, enabling the fruit shell fragments to be fully mixed with the solvent, increasing the contact area, accelerating the release and extraction rate of the pigment, and at the same time helping to reduce the dead zones at the corners and bottom of the tank, preventing the fruit shell fragments from accumulating at the bottom, promoting the uniform distribution and flow of the materials in the whole tank, and improving the mixing uniformity.
[0031] As Figure 3As shown, it further includes: the two rotating rods 9 have different lengths. The rotating rods 9 with different lengths, together with the second helical fins 8, generate stirring flow fields at different heights inside the tank, which helps to form a more complex and comprehensive three-dimensional flow pattern, reduce dead zones, and enable the solvent to contact the husk fragments more evenly.
[0032] As Figure 3 shown, it further includes: the two second helical fins 8 are distributed in a vertically staggered manner with respect to the first helical fin 5. The vertically staggered distribution promotes the vertical mixing of the liquid and husk fragments, including not only horizontal flow but also vertical convection, accelerating the diffusion of pigments and the penetration of the solvent, and improving the extraction efficiency.
[0033] As Figure 3 shown, it further includes: the pitch of the first helical fin 5 is different from that of the second helical fin 8. The different pitch designs can change the flow characteristics of the helical fins in pushing the liquid and solid materials, making the mixing of the liquid and solid more uniform. The pitch of the first helical fin 5 and the solvent is designed to be denser to promote the rapid stirring and penetration of the solvent; while the pitch of the second helical fin 8 may be sparser to adapt to the pushing of the solid materials. Such different pitch designs optimize the hydrodynamics and improve the mixing uniformity.
[0034] As Figure 1 、 Figure 2 and Figure 3 shown, it further includes: a gear set 4, which is arranged on the rotating rod 6 and the two rotating rods 9; and the gear set 4 is located inside the driving frame 2. A driving gear is sleeved on the top of the rotating rod 6, and driven gears are sleeved on the tops of the two rotating rods 9. The driving gear meshes with the driven gears, and the driving gear and the driven gears rotate in opposite directions.
[0035] As Figure 2 、 Figure 4 and Figure 5 shown, it further includes: a discharge part 10, which is connected and arranged at the bottom of the extraction tank 1. The discharge part 10 includes: a discharge pipe 101, which is connected and arranged at the bottom of the extraction tank 1. By setting the discharge part 10, after the extraction is completed, it is necessary to separate the camellia husk fragments from the solution containing pigments for solid-liquid separation to avoid unified discharge; a first valve is arranged between the discharge pipe 101 and the extraction tank 1 to facilitate controlling the entry of the camellia husk fragments and the solution into the discharge pipe 101.
[0036] As Figure 2 、 Figure 4 and Figure 5As shown, it further includes a drain pipe 102, which is communicatively connected to the discharge pipe 101. By providing the drain pipe 102, a detachable filter screen is provided between the drain pipe 102 and the discharge pipe 101 to block the fruit peel fragments and prevent them from being discharged together with the liquid. At the same time, a second valve is provided between the drain pipe 102 and the discharge pipe 101 to facilitate controlling the liquid to flow from the discharge pipe 101 into the drain pipe 102.
[0037] As Figure 4 and Figure 5 shown, it further includes: the top of the discharge pipe 101 is conical. A third valve is provided at the bottom of the discharge pipe 101 to facilitate controlling the complete discharge of the fruit peel fragments; the conical design can utilize the principle of gravity to cause the liquid to concentrate towards the conical tip when flowing downward, accelerating the flow rate, thereby more efficiently guiding the extracted liquid pigment solution towards the drain pipe 102 for discharge and improving the extraction efficiency.
[0038] As Figure 5 shown, it further includes: a plurality of diversion grooves 103, which are provided on the inner wall of the discharge pipe 101. By providing the diversion grooves 103, they can be arranged in a wavy shape. The wavy diversion groove 103 design can simulate the form of natural fluctuations, increasing the dynamic variability of the liquid flow in the discharge pipe 101, promoting the smooth flow of the liquid, reducing stagnation, and accelerating the discharge efficiency.
[0039] For the technical solution provided by the present utility model, the fruit shell fragments and the solution are respectively poured into the extraction tank 1 through the feed valve and the liquid inlet valve. The peripheral controller is used to start the operation of the stepping motor 3, driving the rotating rod 6 to rotate. With the cooperation of the gear set 4, the rotating rod 9 is driven to rotate. The rotating rod 6 drives the stirring blades 7 to rotate, pushing the fruit shell fragments deposited at the bottom upward. Then, through the opposite rotation of the first spiral blade 5 and the two second spiral blades 8, a reverse flow is formed in cooperation to accelerate the mixing of the fruit shell fragments and the solution. After the extraction is completed, the first valve is opened to allow the solution and the fruit shell fragments to enter the discharge pipe 101. Then, the second valve is opened to discharge the liquid from the drain pipe 102. After the liquid discharge is completed, the third valve is opened to discharge the fruit shell fragments from the bottom of the discharge pipe 101.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. Additionally, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
