Description

Technical Field

[0001] This utility model relates to the field of edible oil processing technology, specifically to an edible oil filtration and decolorization device. Background Technology

[0002] Edible oil, also known as cooking oil, refers to animal or vegetable fats used in food preparation. Common edible oils are mostly vegetable oils, including rapeseed oil, peanut oil, hemp seed oil, corn oil, and olive oil. Even after filtration and other processes during production, edible oils may still contain natural pigments such as chlorophyll and carotene, as well as oxidized pigments produced during processing, which can affect their color and quality. Therefore, decolorizing agents are often mixed with the edible oil for decolorization treatment.

[0003] Traditional edible oil filtration and decolorization devices lack effective anti-sticking mechanisms. Over prolonged use, decolorizing agents and grease tend to adhere to the inner walls, leading to several shortcomings in practical application. For example, this directly impacts product quality. The decolorizing agents and grease adhering to the inner walls gradually accumulate, forming a stubborn layer of dirt. During subsequent decolorization and filtration processes, this dirt may detach and mix into the edible oil, causing cloudiness and increased impurities, severely affecting the color, taste, and hygiene indicators of the edible oil, thus reducing product quality. Furthermore, it reduces production efficiency. As the amount of deposits on the inner walls increases, it obstructs fluid flow within the device, hindering the flow of edible oil and significantly reducing the filtration and decolorization speed, thereby extending the production cycle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: an edible oil filtration and decolorization device, including a decolorization box 1. A cover plate 11 is fixedly installed on the upper end of the decolorization box 1 by screws. A sleeve 12 is fixedly installed in the middle of the lower end of the cover plate 11. A rotating cylinder 13 is rotatably installed in the middle of the sleeve 12. Multiple fixing rods 15 are evenly fixedly installed around the lower end of the rotating cylinder 13, penetrating the sleeve 12. A scraper 16 is fixedly installed at one end of each fixing rod 15. A stirring fan blade 17 is fixedly installed in the middle of each fixing rod 15. A spring 18 is fixedly installed at the lower part of the middle of the rotating cylinder 13. A fixed spring 18 is installed on one side of the upper end of the rotating cylinder 13. A toothed plate 19 is installed, a guide groove 14 is opened on one side of the rotating drum 13, a rotating shaft 22 is rotatably installed in the middle of the upper end of the sleeve 12, a semi-circular gear 23 is fixedly installed in the middle of the rotating shaft 22, a motor 21 is fixedly installed on one side of the middle of the upper end of the rotating shaft 22, a guide rod 20 is fixedly installed on one side of the middle of the sleeve 12, the scraper 16 abuts against the inner wall of the decolorizing box 1, the other end of the spring 18 is fixedly connected to the lower end of the middle of the sleeve 12, the guide rod 20 and the guide groove 14 are slidably engaged, the output end of the motor 21 is fixedly connected to one end of the rotating shaft 22, and the semi-circular gear 23 and the toothed plate 19 mesh.

[0024] In this embodiment, the decolorizing chamber 1, through the coordinated operation of its components, effectively solves the problem of wall adhesion, thereby improving the decolorization effect. During use, the motor 21 drives the rotating shaft 22 to rotate, and the semi-circular gear 23 meshes with the toothed plate 19, driving the rotating drum 13 to reciprocate up and down. Simultaneously, the guide rod 20 cooperates with the guide groove 14, allowing the rotating drum 13 to rotate during its movement. During the rotation of the rotating drum 13, the fixing rod 15 drives the scraper 16 to adhere tightly to the inner wall of the decolorizing chamber 1, continuously scraping away the decolorizing agent, oil stains, and other substances adhering to the chamber wall. The stirring fan blades 17 simultaneously stir, preventing material accumulation near the chamber wall, fundamentally reducing wall adhesion, ensuring the smooth progress of the decolorization process, and avoiding... To address the material waste and equipment cleaning difficulties caused by material sticking to the walls, the stirring blades 17, driven by the rotating drum 13, thoroughly stir and mix the edible oil and decolorizing agent, ensuring full contact between the decolorizing agent and pigment, accelerating the adsorption reaction, and thus improving decolorization efficiency and uniformity. Simultaneously, the reciprocating motion and rotation of the rotating drum 13 break up dead zones in the material flow within the decolorization chamber 1, promoting mass transfer and further enhancing the decolorization effect, ensuring uniform color of the edible oil. Furthermore, the cover plate 11, secured with screws, is easy to disassemble, facilitating inspection, cleaning, and maintenance of the decolorization chamber 1 during downtime. This further reduces equipment maintenance difficulty and time costs, improving work efficiency.

[0025] Example 2: As Figure 1-3 As shown, a connecting pipe 28 is fixedly connected to the lower end of the decolorizing tank 1. A liquid pump 29 is fixedly installed on one side of the decolorizing tank 1. One end of the connecting pipe 28 is fixedly connected to the liquid pump 29. One end of the liquid pump 29 is fixedly connected to a separation tank 30. One end of the separation tank 30 is fixedly connected to an oil drain pipe 31. A valve 32 is fixedly installed above one end of the oil drain pipe 31. An oil guide pipe 27 is fixedly connected to one side of the middle part of the decolorizing tank 1. Handles 24 are fixedly installed at both ends of the middle part of the upper end of the cover plate 11. A feeding cylinder 25 is fixedly connected to one side of the middle part of the upper end of the cover plate 11. A baffle 26 is rotatably installed in the middle of the feeding cylinder 25. Electric heating rods 10 are fixedly installed on both sides of the middle part of the lower end of the cover plate 11.

[0026] In this embodiment, the design of the feeding cylinder 25 with the rotatable baffle 26 facilitates precise control of the amount and timing of the decolorizing agent by the operator, reducing errors and dust problems caused by direct manual addition. The electric heating rods 10 are evenly distributed at the lower end of the cover plate 11, which can quickly and evenly heat the edible oil in the decolorizing tank 1, enhance the reactivity of the decolorizing agent and the edible oil, accelerate the adsorption process, and at the same time help reduce the viscosity of the oil, ensuring smooth delivery by the liquid pump 29 and improving the overall processing efficiency. The liquid pump 29, the connecting pipe 28 and the separation tank 30 form an efficient transmission path, and the liquid pump 29 quickly delivers the decolorized edible oil. The oil is stably transported to the separation tank 30 for solid-liquid separation. The oil drain pipe 31 and valve 32 are combined to facilitate the control of the discharge of the separated edible oil, which is convenient for subsequent storage or filling processes. The valve 32 can flexibly control the oil discharge speed and start and stop, avoiding oil waste and external pollution. The oil guide pipe 27 can realize the diversion or circulation of edible oil according to production needs, enhancing the system flexibility. The handle 24 on the cover plate 11 is designed to facilitate easy disassembly and installation of the cover plate 11 by operators, which greatly reduces the difficulty of inspecting, maintaining and cleaning the internal components of the decolorizing tank 1, such as the scraper 16 and the stirring fan blade 17.

[0027] like Figure 1-5As shown, during use, the edible oil to be decolorized is introduced into the decolorization tank 1 through the oil guide pipe 27. Then, the cover plate 11 is opened through the handle 24. As needed, an appropriate amount of decolorizing agent is added to the decolorization tank 1 through the feeding cylinder 25. Subsequently, the electric heating rod 10 is activated to heat the edible oil in the decolorization tank 1. During the process, the electric heating rod 10 can ensure that the edible oil is heated evenly, reduce the viscosity of the oil, and at the same time improve the reactivity of the decolorizing agent with pigments and other impurities in the edible oil, creating favorable conditions for the subsequent decolorization process. The motor sleeve 21 is activated, and the output end of the motor sleeve 21 drives the rotating shaft 22 to rotate. The semi-circular gear 23 on the rotating shaft 22 meshes with the toothed plate 19 on the rotating drum 13, causing the rotating drum 13 to move up and down reciprocally. At the same time, the guide rod 20 slides and engages with the guide groove 14 on the rotating drum 13, restricting the movement trajectory of the rotating drum 13 and causing it to rotate while moving up and down. The fixed rod 15 at the lower end of the rotating drum 13 moves with the drum 13. The stirring blades 17 on the fixed rod 15 thoroughly stir the edible oil and decolorizing agent, allowing the decolorizing agent to fully contact the pigments in the edible oil and undergo an adsorption reaction, thereby achieving the purpose of decolorization. In addition, the scraper 16 at one end of the fixed rod 15 is in close contact with the inner wall of the decolorization tank 1. During the movement of the rotating drum 13, the scraper 16 continuously scrapes away the decolorizing agent and oil stains adhering to the inner wall of the decolorization tank 1, preventing their accumulation and ensuring the decolorization effect and normal operation of the equipment. After decolorization is completed, the liquid pump 29 is started. The liquid pump 29 transports the edible oil in the decolorization tank 1 to the separation tank 30 through the connecting pipe 28 for solid-liquid separation. The separated solid impurities such as the decolorizing agent are left in the separation tank 30, while the decolorized edible oil is discharged through the oil drain pipe 31. Opening the valve 32 can control the discharge speed and flow rate of the edible oil in the oil drain pipe 31, so as to transport the decolorized edible oil to subsequent storage or processing equipment.
