Description

Technical Field

[0001] This utility model relates to a continuous filtration device for cold-pressed almond oil production, belonging to the field of almond oil pressing technology. Background Technology

[0002] Almonds are the kernels of apricot kernels, used both as food and medicine. They are rich in protein, oils, vitamins, minerals, and other nutrients, with a particularly high oil content. Almond oil, produced from almonds, is high in unsaturated fatty acids, which are very beneficial to health. Furthermore, almond oil is rich in minerals, protein, and various vitamins, making it an excellent plant oil for skin care and moisturizing. However, almond oil production is limited, so it is often processed into high-grade edible oil, skincare products, and raw materials for other products. To maintain the excellent health benefits of almond oil, processing typically avoids hot pressing and organic solvent extraction methods, instead using hydraulic pressing equipment to cold-press the almonds to produce almond oil.

[0003] The raw almonds to be processed are dry, hard, and brittle, producing a significant amount of fine residue during cold pressing. To improve the quality of almond oil, this residue needs to be filtered and separated during pressing to prevent it from contaminating the oil and affecting its quality and shelf life. Current methods for cold-pressing almond oil involve feeding almonds into an oil press and using hydraulic pressure to extract the oil. While hydraulic oil presses include filters to remove the residue, the filtration effect is poor, with low efficiency, and fine almond residue may still remain, impacting the oil's quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a continuous filtration device for cold-pressed almond oil production that can perform multiple, continuous, and efficient filtration of almond oil.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A continuous filtration device for cold-pressed almond oil production includes a base, a fixed frame fixedly mounted on the top of the base, a hydraulic cylinder fixedly mounted on the top of the fixed frame, a pressure plate fixedly mounted on the output end of the hydraulic cylinder extending into the fixed frame, an oil pressing cylinder fixedly mounted inside the fixed frame, an oil collecting tray disposed below the oil pressing cylinder, and a continuous filtration structure disposed on the oil pressing cylinder. The continuous filtration structure includes a first fixed frame disposed at the bottom of the oil pressing cylinder, a first filter screen fixedly mounted inside the first fixed frame, a second fixed frame disposed at the bottom of the first fixed frame, a second filter screen fixedly mounted inside the second fixed frame, and a third fixed frame disposed at the bottom of the second fixed frame, a third filter screen fixedly mounted inside the third fixed frame, wherein the aperture of the first filter screen, the second filter screen, and the third filter screen decreases sequentially.

[0007] Furthermore, two support frames are symmetrically fixedly installed on both sides of the oil pressing cylinder, the first fixed frame, and the second fixed frame. A spring is fixedly installed on one side of the support frame, and a support rod connected to the spring is movably installed on the support frame. A locking block is fixedly installed on one end of the support rod inside the support frame. Limit blocks are fixedly installed on the surfaces of the first fixed frame, the second fixed frame, and the third fixed frame.

[0008] Furthermore, the diameter of the card block matches the inner diameter of the slot on the limiting block, and the shape of the card block is set as trapezoidal.

[0009] Furthermore, a plurality of first magnetic blocks are fixedly installed on the inner wall of the fixing frame, and a second magnetic block is fixedly installed on one side of the support rod.

[0010] Furthermore, sealing rings are fixedly installed on the top of the first fixed frame, the second fixed frame, and the third fixed frame, and sealing grooves are opened at the bottom of the oil pressing cylinder, the first fixed frame, and the second fixed frame.

[0011] Furthermore, a telescopic cylinder is fixedly installed on the top of the oil collection pan, and a sealing plate adapted to the bottom of the third fixed frame is fixedly installed on the top of the telescopic cylinder.

[0012] Furthermore, two electric telescopic rods are fixedly installed on the surface of the base, and fixing blocks connected to the electric telescopic rods are fixedly installed on both sides of the sealing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application, through the design of a continuous filtration structure, enables multiple and continuous filtration of pressed almond oil. The pore sizes of the first, second, and third filter screens in the first, second, and third fixed frames decrease sequentially, continuously filtering out fine almond residue from the almond oil. This effectively prevents fine almond residue from mixing into the almond oil, thus improving its quality. Furthermore, the cone-shaped design of the first, second, and third filter screens, with their concave center, causes the almond residue to tend to collect at the center, reducing clogging and improving filtration efficiency. The locking and fixing structure of the locking block and limiting block facilitates the cleaning of the filtered almond residue, making it convenient to use and highly practical.

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 5The continuous filtration device for cold-pressed almond oil production shown includes a base 1, a fixed frame 2 fixedly installed on the top of the base 1, a hydraulic cylinder 3 fixedly installed on the top of the fixed frame 2, a pressure plate 4 fixedly installed on the output end of the hydraulic cylinder 3 extending into the fixed frame 2, an oil pressing cylinder 5 fixedly installed inside the fixed frame 2, an oil collecting tray 6 provided below the oil pressing cylinder 5, and a continuous filtration structure 7 provided on the oil pressing cylinder 5. The continuous filtration structure 7 includes a first fixed frame 8 provided at the bottom of the oil pressing cylinder 5, a first filter screen 9 fixedly installed inside the first fixed frame 8, a second fixed frame 10 provided at the bottom of the first fixed frame 8, a second filter screen 11 fixedly installed inside the second fixed frame 10, a third fixed frame 12 provided at the bottom of the second fixed frame 10, and a third filter screen 13 fixedly installed inside the third fixed frame 12. The apertures of the first filter screen 9, the second filter screen 11, and the third filter screen 13 decrease sequentially. By setting up the continuous filtration structure 7, the pressed almond oil can be filtered multiple times and continuously. Since the pore sizes of the first filter screen 9, the second filter screen 11, and the third filter screen 13 set in the first fixed frame 8, the second fixed frame 10, and the third fixed frame 12 decrease sequentially, the fine almond residue in the almond oil can be continuously filtered, effectively preventing fine almond residue from being mixed into the almond oil. The first filter screen 9, the second filter screen 11, and the third filter screen 13 are set in a conical shape, with their center positions concave, so that the almond residue tends to gather at the center during the filtration process, reducing the blockage caused to the almond oil discharge.

[0023] In this embodiment, as Figure 1 As shown, two support frames 14 are symmetrically fixedly installed on both sides of the oil pressing cylinder 5, the first fixed frame 8, and the second fixed frame 10. A spring 15 is fixedly installed on one side of the support frame 14, and a support rod 16 connected to the spring 15 is movably installed on the support frame 14. A locking block 17 is fixedly installed on one end of the support rod 16 located inside the support frame 14. Limiting blocks 18 are fixedly installed on the surfaces of the first fixed frame 8, the second fixed frame 10, and the third fixed frame 12. The first fixed frame 8, the second fixed frame 10, and the third fixed frame 12 are stacked together. 2. The locking block 17 and the limiting block 18 are engaged to fix the frame. Pulling the support rod 16 will pull the locking block 17 outward to disengage it from the limiting block 18. After the locking block 17 and the limiting block 18 are separated, the first fixing frame 8, the second fixing frame 10 and the third fixing frame 12 can be disassembled to facilitate the cleaning of the filtered almond residue. By matching the diameter of the locking block 17 with the inner diameter of the slot on the limiting block 18, the engagement between the locking block 17 and the limiting block 18 is made more secure, preventing the first fixing frame 8, the second fixing frame 10 and the third fixing frame 12 from shaking.

[0024] The diameter of the locking block 17 matches the inner diameter of the slot on the limiting block 18, and the shape of the locking block 17 is trapezoidal. Multiple first magnetic blocks 19 are fixedly installed on the inner wall of the fixing frame 2, and a second magnetic block 20 is fixedly installed on one side of the support rod 16. The trapezoidal shape of the locking block 17, with one end inclined, facilitates direct compression of the locking block 17 by the limiting block 18 during installation to complete the locking process. Because the support rod 16 is connected to a spring 15, it has a return elasticity. During disassembly, pulling the support rod 16 until the second magnetic block 20 at one end adheres to the first magnetic block 19 allows the support rod 16 to be fixed by the attraction of the first magnetic block 19 and the second magnetic block 20, preventing the locking block 17 from resetting during disassembly and affecting the disassembly process.

[0025] In this embodiment, as Figure 1 As shown, sealing rings 21 are fixedly installed on the top of the first fixed frame 8, the second fixed frame 10, and the third fixed frame 12, and sealing grooves 22 are opened at the bottom of the oil pressing cylinder 5, the first fixed frame 8, and the second fixed frame 10. After the first fixed frame 8, the second fixed frame 10, and the third fixed frame 12 are connected, the sealing rings 21 are inserted into the sealing grooves 22. After the sealing rings 21 and the sealing grooves 22 are connected, the joint of the first fixed frame 8, the second fixed frame 10, and the third fixed frame 12 can be sealed.

[0026] A telescopic cylinder 23 is fixedly installed on the top of the oil collection tray 6, and a sealing plate 24 adapted to the bottom of the third fixed frame 12 is fixedly installed on the top of the telescopic cylinder 23. Two electric telescopic rods 25 are fixedly installed on the surface of the base 1, and fixing blocks 26 connected to the electric telescopic rods 25 are fixedly installed on both sides of the sealing plate 24. When the electric telescopic rods 25 are activated, their output ends extend and pull the sealing plate 24 through the fixing blocks 26, causing the sealing plate 24 to rise and fit against the bottom of the third fixed frame 12. When the sealing plate 24 rises, it can pull the telescopic cylinder 23, thereby surrounding the third fixed frame 12 and the oil collection tray 6, preventing the almond oil from falling into the oil collection tray 6 and being contaminated by dust and impurities.

[0027] The working process of the continuous filtration device for cold-pressed almond oil production provided in this embodiment is as follows:

[0028] After the almonds are put into the oil press cylinder 5, the hydraulic cylinder 3 is activated to drive the pressure plate 4 to descend and press the almonds to extract oil. The almond oil flows from the oil press cylinder 5 into the first fixed frame 8, and then passes through the first filter screen 9, the second filter screen 11 and the third fixed frame 12 in sequence. Since the pore sizes of the first filter screen 9, the second filter screen 11 and the third filter screen 13 set in the first fixed frame 8, the second fixed frame 10 and the third fixed frame 12 decrease in sequence, the almond oil can be continuously filtered, effectively preventing fine almond residue from being mixed in with the almond oil. In addition, the shape of the first filter screen 9, the second filter screen 11 and the third filter screen 13 is set as a concave cone at the center, so that the almond residue tends to gather at the center during the filtration process, reducing the blockage caused to the almond oil discharge.

[0029] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
