Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sunflower oil processing, and in particular to a zero-trans fatty acid sunflower oil refining and processing system. Background Art
[0002] Sunflower oil, an important edible oil, undergoes a refining process that includes boiling. After boiling, residues may form on the surface of the sunflower oil, affecting its quality. To clean surface residues, patent publication number CN216604225U discloses a boiling device for sunflower oil production. The device comprises a boiling tank body, a displacement structure, and a fine filtration structure. The displacement structure drives the fine filtration structure to move axially within the boiling tank body, and the fine filtration structure is used to filter and collect residues on the oil surface three times. However, since the oil flows into the fine filtration structure upon contact with it, the oil has a poor gathering effect on the residues on the oil surface, affecting the efficiency of residue collection. Summary of the Invention

The fine filtering structure includes a filter mesh screwed into the interior of the shell. The side wall of the shell is rotatably connected to an oil drain pipe. A gear is fixed to the oil drain pipe, and the gear is engaged with a rack fixed to the interior of the boiling tank body. After the fine filtering structure is moved out of the liquid surface under the drive of the displacement structure, the top of the oil drain pipe swings downward to enable the oil in the shell to flow out.
[0005] By adopting the technical solution of the present application, a concave space can be formed on the liquid surface after the shell is moved below the liquid surface, and the residue on the liquid surface can be gathered into the inside of the filter. After the shell is moved out of the liquid surface, the top of the oil drain pipe swings downward to drain the oil in the shell and collect the residue in the filter.

[0016] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.
[0017] See also Figure 1-Figure 3In the related art, sunflower oil, as an important edible oil, is refined through a boiling process. After boiling, residues may remain on the surface of the sunflower oil, affecting its quality. To clean surface residues, patent publication CN216604225U discloses a boiling device for sunflower oil production. The device comprises a boiling tank body 10, a displacement structure 20, and a fine filter structure 30. The fine filter structure 30 comprises a first filter screen 31, a second filter screen 32, and an oil collection tank 33 that functions as a third filter screen. The displacement structure 20 drives the fine filter structure 30 to move axially within the boiling tank body 10, filtering and collecting residues on the oil surface three times.
[0018] However, since the oil will flow into the fine filter structure 30 when it contacts the above-mentioned fine filter structure, the gathering effect of the residue on the surface of the oil is poor, which affects the efficiency of collecting the residue.
[0019] This embodiment provides a zero-trans fatty acid sunflower oil refining and processing system for refining sunflower oil. The system can form a large gathering effect on the residue on the surface of the oil, thereby improving the residue collection efficiency.
[0020] See also Figure 1-Figure 4 In this embodiment, a zero trans fatty acid sunflower oil refining and processing system includes a boiling tank body 10, a displacement structure 20 and a fine filtering structure 30. The fine filtering structure 30 includes a filter screen 31 screwed into the interior of a shell 37. The side wall of the shell 37 is rotatably connected to an oil drain pipe 34. A gear 35 is fixed to the oil drain pipe 34. The gear 35 is engaged with a rack 36 fixed to the interior of the boiling tank body 10. After the fine filtering structure 30 is moved out of the liquid surface under the drive of the displacement structure 20, the top of the oil drain pipe 34 swings downward to enable the oil in the shell 37 to flow out.
[0021] By adopting the technical solution of this embodiment, after the shell 37 moves below the liquid level, a concave space can be formed on the liquid surface, which can gather the residue on the liquid surface into the filter 31. After the shell 37 moves out of the liquid surface, the top of the oil drain pipe 34 swings downward to drain the oil in the shell 37 and collect the residue in the filter 31.
[0022] It should be noted that this embodiment is an improvement on the patent with announcement number CN216604225U as the prior art. The main improvement lies in the overall structural improvement of the fine filtration structure. Compared with the existing fine filtration structure, in this embodiment, the shell 37 is constructed into a cylindrical shape with closed sides and bottom and only the top open. The shell 37 is arranged inside the brewing tank body 10 and maintains a coaxial arrangement with the brewing tank body 10. The displacement structure 20 is connected to the shell 37 to drive the shell 37 to move up and down. The displacement structure 20 can adopt an electric telescopic rod.
[0023] In addition, the filter screen 31 is coaxially arranged with the shell 37. A connecting ring is fixedly connected to the top of the filter screen 31, and the inner diameter of the connecting ring gradually decreases from top to bottom. The connecting ring is screwed into the inside of the shell 37, so that the filter screen 31 is detachably connected to the inside of the shell 37 as a whole, and the collected residue is cleaned.
[0024] In addition, the oil drain pipe 34 is constructed as an L-shape as a whole. The oil drain pipe 34 includes a connecting section and an extension section. The connecting section is arranged along the radial direction of the shell 37, and the connecting section is connected and communicated with the shell 37. The gear 35 is fixed to the connecting section, and the extension section and the connecting section are arranged vertically. The oil drain pipe 34 is evenly distributed along the circumference of the shell 37, and the rack 36 is arranged parallel to the axis of the shell 37. The rack 36 is arranged symmetrically on both sides of the shell 37, and the lower end of the rack 36 is welded to the bottom of the boiling pot body 10.
[0025] It should be noted that, driven by the displacement structure, when the top of the shell drops to a set distance below the liquid level, the top of the oil drain pipe swings upward to be parallel to the axis of the shell, and the top of the oil drain pipe is above the liquid level. At this time, the shell forms a concave space on the liquid surface, and the residue on the liquid surface will gather towards the filter screen inside the shell; when the oil has not yet completely filled the internal space of the shell, the shell moves upward under the drive of the displacement structure. When the shell as a whole is completely moved out of the liquid surface by a set distance, the top of the oil drain pipe swings downward to a horizontal level, and the oil drain pipe as a whole is above the liquid surface. At this time, the oil in the shell flows back to the interior of the boiling tank body 10 through the oil drain pipe under the action of gravity. Such a cycle can efficiently collect the residue on the liquid surface.
[0026] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
