Description

Technical Field

[0001] This utility model relates to the field of oil processing, and more specifically, to a stirring device for oil antioxidant treatment. Background Technology

[0002] Antioxidant treatment is a crucial step in the processing and preservation of oils and fats. Oils and fats are easily affected by oxidation during storage and transportation, leading to spoilage, rancidity, and impacting their flavor, color, and nutritional value; they can even produce substances harmful to human health. Therefore, improving the antioxidant properties of oils and fats is one of the key issues in the oil and fat industry.

[0003] Traditional methods for antioxidant treatment of oils include adding antioxidants, using antioxidant packaging materials, and controlling storage conditions. Among these methods, stirring is a common physical treatment method, which can evenly distribute antioxidants in oils and improve their antioxidant effect. However, due to the viscosity and fluidity of oils, traditional stirring devices are difficult to ensure that antioxidants are thoroughly mixed in the oil, easily resulting in localized excessively high or low concentrations. Utility Model Content

[0004] Based on the above-mentioned technical problems, this utility model proposes a stirring device for oil and fat antioxidant treatment.

[0005] A stirring device for anti-oxidation treatment of oils includes: a stirring tank with multiple support legs at the bottom for support, and an annular base plate at the bottom of each support leg; a top cover with a feed pipe and a vent pipe on the top cover, a stirring motor at the center of the top cover, the stirring motor being axially connected to a stirring shaft, the stirring shaft passing through the top cover and disposed inside the stirring tank, the stirring shaft having helical blades in a spiral structure, and also having circumferentially evenly distributed stirring blades, the stirring blades being arranged in multiple layers and the length of the stirring blades being greater than the diameter of the helical blades, the synchronous rotation of the helical blades and the stirring blades allowing the oil to move in opposite directions vertically; and at least one discharge pipe at the bottom of the stirring tank.

[0006] Preferably, an oil inlet pipe is provided on one side of the feed pipe, a one-way valve is provided at the upper end of the feed pipe, and an antioxidant inlet pipe is provided at the other end of the one-way valve.

[0007] Preferably, a bearing is provided at the lower end of the stirring shaft, the inner ring of the bearing is connected and fixed to the stirring shaft, and the outer ring of the bearing is fixed to the bottom center of the stirring tank.

[0008] Preferably, the stirring blades are all disposed between the pitches of the spiral blades.

[0009] Beneficial effects: 1. This device achieves efficient mixing of oils and antioxidants through spiral blades and multi-layered stirring blades evenly distributed in a circle. This structure allows the oils to generate opposite movements in the vertical direction during stirring, thereby greatly improving the homogeneity of the mixture and ensuring the uniform distribution of antioxidants in the oils. 2. The spiral blades on the stirring shaft and the stirring blades rotate synchronously, causing the oil to flow in multiple directions and all directions in the mixing tank, increasing the stirring efficiency and shear force, thereby achieving uniform mixing in a shorter time. 3. The bearing design at the lower end of the stirring shaft ensures stable rotation of the stirring shaft, reduces wear during long-term operation, and improves the service life and reliability of the equipment. 4. The design of the feed pipe allows oils and antioxidants to enter the mixing tank simultaneously, simplifying the operation steps and improving work efficiency. Attached Figure Description

[0010] Figure 1 A schematic diagram of the structure of this utility model is shown; Figure 2 The internal structure diagram of this utility model is shown. Detailed Implementation

[0011] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0012] In this embodiment, as Figures 1-2 The present invention discloses a stirring device for anti-oxidation treatment of oils. The bottom of the stirring tank 1 is provided with multiple support legs 2 for support, and the bottom of the support legs 2 is provided with an annular base plate 3. The top of the stirring tank 1 is provided with a top cover 4, and the top cover 4 is provided with a feed pipe 6 and a vent pipe 14. The vent pipe 14 is opened when feeding. The center of the top cover 4 is provided with a stirring motor 5, which is connected to a stirring shaft 10. The stirring shaft 10 passes through the top cover 4 and is located inside the stirring tank 1. The stirring shaft 10 is provided with spiral blades 12 in a spiral structure. The stirring shaft 10 is also provided with stirring blades 11 evenly distributed in a circle. The stirring blades 11 are arranged in multiple layers and are all arranged between the pitches of the spiral blades 12. The synchronous rotation of the spiral blades 12 and the stirring blades 11 can make the oil move in opposite directions in the vertical direction.

[0013] The stirring blade 11 has a specific structure, which is existing technology and will not be described in detail here. When it rotates, it can cause the grease to tumble up or down. At the same time, the spiral structure of the spiral blade 12 can also cause the grease to surge up or sink down. Moreover, the direction of movement of the grease driven by the spiral blade 12 is opposite to the direction of movement driven by the stirring blade 11.

[0014] In order to avoid the front section of the stirring blade 11 near the stirring shaft 10 from interfering with the spiral blade 12 driving the grease, the front section of the stirring blade 11 is set as a connecting rod (not shown) to reduce its influence on the grease near the spiral blade 12. The twisted blade structure of the rear section of the stirring blade 11 can drive the outer layer of grease to make opposite upward or downward movements.

[0015] The bottom of the mixing tank 1 is provided with at least one discharge pipe 13, which is located on one side of the center of the bottom.

[0016] The feed pipe 6 has an oil inlet pipe 7 on one side and a one-way valve 8 at the upper end of the feed pipe 6. The other end of the one-way valve 8 has an antioxidant inlet pipe 9. The oil and antioxidant can enter the mixing tank 1 at the same time, which simplifies the operation steps and allows the antioxidant and oil to be premixed.

[0017] A bearing 15 is provided at the lower end of the stirring shaft 10. The inner ring of the bearing 15 is connected and fixed to the stirring shaft 10, and the outer ring of the bearing 15 is fixed at the bottom center of the mixing tank 1. The setting of the bearing 15 ensures the stable rotation of the stirring shaft 10, reduces the wear of the equipment during long-term operation, and improves the service life and reliability of the equipment.

[0018] The working process of this device is as follows: The oil is fed into the mixing tank 1 through the oil inlet pipe 7, while antioxidants are added through the antioxidant inlet pipe 9. The mixing motor 5 is started, and the mixing shaft 10 drives the spiral blades 12 and the mixing blades 11 to rotate synchronously, achieving rapid and uniform mixing of the oil and antioxidants. The processed oil is discharged through the discharge pipe for subsequent storage or packaging processes.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
