Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic edible oil processing, and specifically, to a filtering device and method for peanut oil processing. Background Art

[0002] Peanut oil is made from peanut kernels, and its production process mostly uses the pressing method or the leaching method to extract vegetable oil. The pressing method is further divided into the hot pressing method and the cold pressing method. The hot pressing method is to press the peanut kernels after high-temperature steaming and frying. Although it has a strong aroma, it has more impurities. The cold pressing method is to press at room temperature, which can retain vitamin E to a certain extent and is suitable for high-end oil products; Chinese Publication No.: CN222468210U discloses a filtering device for peanut oil processing, including a filtering barrel. The top of the filtering barrel is fixedly connected with a top cover. A grading filtering component is arranged inside the filtering barrel. The grading filtering component includes a filtering disc and a sealing rubber strip. The number of the filtering discs is three, and the three filtering discs are fixedly connected inside the filtering barrel in sequence from top to bottom. This patent conducts multiple filtrations of peanut oil through three filtering discs distributed in a stepped manner from top to bottom. The mesh number of the filter holes at the bottom of the three filtering discs gradually increases, achieving the effect of gradually filtering peanut oil and separating material residues. When the driving box is started, it can control the downward position movement of the three oil pressing plates inside the three filtering discs, so that the oil pressing plates squeeze the material residues filtered by the filter screens at the bottom of the filtering discs from above, which is beneficial to the full utilization of the material residues and improves the filtering effect of peanut oil; Although the above patent uses the control of the displacement of multiple oil pressing plates inside the filtering discs to extract oil and filters through the filter screens, considering that some impurities will deposit at the bottom of the container during the filtering process of peanut oil, these deposited impurities will affect the quality of peanut oil, and peanut oil and impurities will be discharged together during the discharging process, which makes it necessary to perform secondary or multiple filtrations to obtain peanut oil with excellent quality; In view of this, we propose a filtering device and method for peanut oil processing.

[0022] As Figures 6 - 7 shown, the fixed column 163 on the side away from the discharge port 15 is rotatably connected to a first reciprocating lead screw 361 through a cross column. A second runner 36 is fixedly connected to the upper end of the first reciprocating lead screw 361. The second runner 36 is in contact with the inner wall of the rotating cover 31. A piston disk 362 is threadedly connected to the outer wall of the first reciprocating lead screw 361. The diameter of the piston disk 362 is the same as the diameter of the first chamber 1621.

[0023] It can be seen from this that when it is necessary to ensure the separation of impurities and peanut oil during the discharge of peanut oil, as Figures 2 - 5 shown, first, the peanut oil pressed in the previous process will be transported from the peripheral pressing device to the filter tube 2. After preliminary simple filtration by the filter screen 21, larger peanut fibers and other impurities are separated from the peanut oil. Then, it passes through the feeding pipeline 14 and is finally stored in the storage tank 1. It should be noted that if the peanut oil is extracted by the hot pressing method, it will be cooled before the filter tube 2; After the peanut oil in the storage tank 1 stands for a certain period of time, the impurities in the peanut oil will gradually fall to the bottom of the funnel 11 for deposition. After the deposition of the peanut oil impurities is completed, the adjustment assembly 3 is started. Driven by the motor 321, the first rotating rod 331 drives the first gear 3311 to rotate. At the same time, the electric slide rail 13 drives the driving ring 131 to rotate. During the rotation of the driving ring 131, the stepped part of the inner stepped groove 1311 will pass through the position of the telescopic column 3421 and drive the telescopic column 3421 to rotate to one side. At this time, the rotating telescopic column 3421 will drive the extension rod 342, the triangular plate 34, the third gear 35 and the first runner 352 to rotate and shift to one side together, so that the left third gear 35 gradually approaches the first gear 3311, and at the same time, the right first runner 352 gradually adheres to the inner wall of the rotary cover 31. At this time, the first gear 3311 driven by the motor 321 will drive the left third gear 35 to rotate. At the same time, under the transmission of the second gear 333, the right third gear 35 and the first runner 352 will rotate together, and the rotation of the first runner 352 will drive the rotary cover 31 to rotate. At this time, the rotary cover 31 will drive the second runner 36 and the first reciprocating lead screw 361 to rotate, so that the piston disk 362 slowly moves downward, as Figure 3 shown. At this time, the piston disk 362 will squeeze the space on the right side of the partition 16, making the internal pressure on the right side increase. At this time, the peanut oil will slowly flow into the space on the left side of the partition 16, and then open the valve outside the discharge port 15 to discharge the peanut oil from the discharge port 15. This makes the peanut oil and impurities be discharged in a fault during the discharge process, avoiding the influence of impurities on the discharged peanut oil; Meanwhile, during the gradual downward movement of the piston disk 362, the telescopic rod 37 drives the circular cover plate 371 to continuously move downward. Under the condition of pressurizing the space on the right side of the partition plate 16, the circular cover plate 371 covers the impurities at the bottom of the funnel 11. When the pressure in the right space is relatively high, the impurities will flow into the exhaust holes at the bottom of the circular cover plate 371, preventing the pressure at the bottom of the funnel 11 from gradually increasing during the downward movement and blocking of the circular cover plate 371, and preventing the impurities from flying into the space on the left side of the partition plate 16. When the circular cover plate 371 moves downward to be in contact with the inner wall of the funnel 11, a part of the funnel 11 at the lower end of the circular cover plate 371 is sealed, and then the discharge port at the bottom of the funnel 11 is opened to discharge the impurities and a small amount of peanut oil together, avoiding the impurities depositing in the storage tank 1 and contaminating the remaining peanut oil without being effectively processed.

[0024] Embodiment 2. This embodiment provides a method for using a filtering device for peanut oil processing, including the following steps: S1. First, the peanut oil conveyed to the filter pipe 2 in the previous process is filtered through the filter screen 21 and enters the storage tank 1 through the feed pipe 14. S2. Then, after the impurities in the peanut oil precipitate for a certain period of time, the valves of the feed pipe 14 and the discharge port 15 are closed to make the entire storage tank 1 in a sealed environment. S3. Then, through the mutual cooperation of the adjustment assembly 3 and the rotation assembly 33, the peanut oil on both sides of the partition plate 16 is extruded and discharged from the discharge port 15. S4. Finally, the filtered peanut oil is collected at the discharge port 15, and the impurities and filter residues are discharged at the bottom of the funnel 11.
