Description

Technical Field

[0001] This invention relates to the field of peanut oil production technology, specifically to a peanut oil production pressing and purification device. Background Technology

[0002] Peanut oil production is a standardized process integrating physical processing and fine chemicals. The entire process revolves around raw material safety, oil extraction, and quality refining. Production begins with raw material pretreatment, which involves screening, removing stones, mold, and impurities. After shelling and rolling, hot pressing requires steaming and roasting to activate the oil, while cold pressing maintains a low temperature. Oil extraction is divided into two types: pressing and solvent extraction. Hot pressing with a spiral press yields a high oil yield and a rich aroma, making it the mainstream oil for domestic use. Cold pressing retains nutrients and is suitable for high-end products. Solvent extraction has a low residual oil rate and is mostly used for large-scale industrial production. The crude oil after extraction needs to undergo degumming, deacidification, decolorization, and deodorization refining to remove impurities such as phospholipids and free fatty acids, making it meet national edible oil standards.

[0003] Peanut oil pressing and purification consists of two main stages: physical pressing for oil extraction and crude oil refining. The entire process primarily utilizes physical processes to ensure the safety and quality of the oil. In the pressing stage, peanuts are first screened to remove impurities, shelled, and rolled. Hot pressing requires steaming and roasting at around 120℃ before high-pressure pressing using a screw press to extract crude oil. This process yields a high oil yield and a rich aroma, and is the mainstream method. Cold pressing, on the other hand, is done at low temperatures to retain more nutrients and is often used for high-end oil products. After pressing, crude oil and peanut cake are separated. The crude oil contains impurities and requires further purification. The refining process involves degumming to remove phospholipids, deacidification to neutralize free fatty acids, decolorization to adsorb pigments, and deodorization to remove off-odors. Some oil products also require low-temperature dewaxing. Throughout the process, process parameters are strictly controlled, and indicators such as aflatoxin and acid value are tested to ensure compliance with national standards for edible oils. The final product is clear, stable, and ready to be consumed.

[0004] In existing technologies, the crude oil produced by high-pressure static extrusion of peanut raw materials has typical characteristics of many impurities, high viscosity, and fine particles. It is not only mixed with solid particles such as peanut residue and broken shell fibers generated during the pressing process, but also rich in viscous macromolecular impurities such as phospholipids and protein colloids. These impurities have small particle sizes and strong surface adhesion, and are very easy to form a stable mixture with the oil. When the crude oil is physically intercepted and purified by multi-layer filter cloth, the filtration accuracy and permeability of the filter cloth continuously decline. Not only does the turbidity of the filtered crude oil increase and the impurity removal effect become significantly worse, but the flow resistance of the crude oil also increases sharply due to micropore blockage. The filtration throughput per unit time decreases significantly, and the filtration efficiency continues to decline with the extension of the usage time, making it impossible to maintain a stable purification effect and reducing the quality and purity of peanut oil. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a peanut oil production pressing and purification apparatus to solve the technical problems mentioned above in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a peanut oil production pressing and purification device, comprising a device body, a filter cylinder, a filter disc, and an oil filling platform, wherein multiple sets of device bodies are installed on the upper end of the oil filling platform, a filter cylinder is installed inside the device body, and a filter disc is movably installed inside the device body;

[0007] A pressure plate is movably installed inside the filter cylinder. Multiple sets of first filter holes are opened on the side wall of the filter cylinder. Multiple sets of second filter holes are opened on the outer wall of the filter disc. The diameter of the multiple sets of second filter holes is smaller than the diameter of the multiple sets of first filter holes. A discharge pipe is installed inside the main body of the device and is movably connected to the filter disc.

[0008] The main body of the device is equipped with a support base, which is connected to the filter cartridge. A drive motor is installed inside the support base, and a drive shaft is installed at the output end of the drive motor. Multiple sets of connecting rods are installed at one end of the drive shaft, and one end of each set of connecting rods is connected to the filter disc.

[0009] By adopting the above technical solution, the problem of pressing and purifying peanut oil is solved. The filter cylinder, as the core cavity of peanut pressing, provides a stable space for pressing peanut kernels. The first filter hole on its side wall adopts a uniformly distributed fine pore design, which can accurately intercept larger impurities such as peanut residue and coarse fibers, realizing the initial filtration of peanut oil and laying the foundation for subsequent purification. With the help of the rotatable filter disc, centrifugal force is generated under the drive motor, so that the peanut oil after initial filtration can achieve efficient separation of oil and residue under centrifugal action. The second filter hole on the filter disc has a smaller pore size than the first filter hole, which can further intercept the fine impurities remaining in the peanut oil, realizing secondary fine filtration and improving the quality and purity of peanut oil.

[0010] The present invention is further configured such that the support base has multiple sets of reserved holes, and the diameter of each set of reserved holes is larger than the diameter of each set of first filter holes, and the upper end of each set of first filter holes is designed in a trumpet shape.

[0011] Preferably, after the peanut oil flows from the first filter hole to the upper end of the support base, the peanut oil falls onto the upper end of the filter plate through multiple sets of reserved holes, and the diameter of the multiple sets of reserved holes is larger than the diameter of the multiple sets of first filter holes, so as to avoid impurities inside the peanut oil from clogging the reserved holes and ensure smooth flow of the entire oil circuit.

[0012] The present invention is further configured such that the filter disc is funnel-shaped, a limiting ring is installed at the bottom of the filter disc, a reserved groove is provided at the upper end of the discharge pipe, and the outer wall of the limiting ring is movably connected to the inner wall of the reserved groove.

[0013] Preferably, the filter disc is displaced towards the center end under the action of centrifugal force. The filter disc is set in a funnel shape, and the impurities on the filter disc will gradually gather to the center end of the filter disc. Then, through the discharge pipe connected to the center end of the filter disc, the impurities fall to the bottom end of the discharge pipe under the dual action of gravity and centrifugal force. The limiting ring rotates inside the reserved groove, which improves the stability of the filter disc.

[0014] The present invention is further configured such that an impurity collection box is provided inside the oil filling platform, and one end of the discharge pipe is connected to the impurity collection box.

[0015] Preferably, the impurities fall to the bottom of the discharge pipe and then enter the impurity collection box. The impurity collection box adopts a sealed design to prevent impurities from scattering and polluting the production environment, while facilitating subsequent regular cleaning and recycling.

[0016] The present invention is further configured such that one end of the main body of the device is provided with an oil outlet pipe, and an oil outlet head is installed at one end of the oil outlet pipe.

[0017] Preferably, the oil outlet is activated, and the peanut oil inside the main body of the device is discharged through the oil outlet pipe.

[0018] The present invention is further configured such that a hydraulic cylinder is mounted on the upper end of the oil filling platform, and one end of the hydraulic cylinder is provided with a hydraulic pipe connected to an external hydraulic device, and a hydraulic rod is provided inside the hydraulic cylinder.

[0019] Preferably, the hydraulic device introduces hydraulic oil into the hydraulic cylinder through a hydraulic pipe, and the hydraulic oil forms a stable pressure inside the hydraulic cylinder, pushing the hydraulic rod to move downward at a uniform speed in the vertical direction.

[0020] The present invention is further configured such that one end of the hydraulic rod is connected to the pressure plate, and the bottom end of the pressure plate is provided with an anti-slip protrusion.

[0021] Preferably, the hydraulic rod pushes the pressure plate downward, and the pressure plate squeezes the peanuts inside the filter cylinder. The bottom of the pressure plate is provided with an anti-slip protrusion structure, which can increase the contact area with the peanut kernels and prevent the peanut kernels from sliding during the squeezing process.

[0022] The present invention is further configured such that a base plate is movably installed inside the filter cartridge, and the outer wall of the base plate is movably connected to the inner wall of the filter cartridge. Multiple sets of support columns are installed at the upper end of the base plate, and the inner wall of the pressure plate is movably connected to the outer wall of the multiple sets of support columns. Limiting blocks are installed at the upper ends of the multiple sets of support columns, and rubber pads are provided at the bottom ends of the multiple sets of limiting blocks.

[0023] Preferably, the pressure plate moves upward and moves to the area of ​​multiple sets of limiting blocks. The pressure plate is in contact with the multiple sets of limiting blocks. As the pressure plate continues to move upward, it drives multiple sets of support columns to move upward smoothly, thereby driving the base plate to move upward as well.

[0024] The present invention is further configured such that a spiral conveying device is provided outside the oil filling platform, and an operating platform is provided outside the side of the oil filling platform.

[0025] Preferably, the screw conveyor smoothly and at a constant speed introduces the cleaned and screened peanut kernels into the filter cylinder from the feed inlet at the top of the filter cylinder. After the bottom plate moves the pressed cake out of the filter cylinder, the workers can quickly recycle the pressed cake at the top of the bottom plate using the operating platform reserved on the side of the oil filling platform.

[0026] The invention is further configured such that a conveyor belt may be added to the upper end of the oil filling platform, and the conveyor belt operates intermittently.

[0027] Preferably, the conveyor belt intermittently transports the oil drum to the lower end of the oil outlet.

[0028] In summary, the present invention has the following main beneficial effects:

[0029] 1. This invention solves the problem of pressing and purifying peanut oil by setting up a filter cylinder, a first filter hole, a filter disc, and a second filter hole. The filter cylinder, as the core cavity for peanut pressing, provides a stable space for pressing peanut kernels. The first filter hole on its side wall adopts a uniformly distributed fine pore design, which can accurately intercept larger impurities such as peanut residue and coarse fibers, realizing the initial filtration of peanut oil and laying the foundation for subsequent purification. In conjunction with the rotatable filter disc, centrifugal force is generated under the drive of the motor, so that the peanut oil after initial filtration can achieve efficient separation of oil and residue under centrifugal action. The second filter hole on the filter disc has a smaller pore size than the first filter hole, which can further intercept the fine impurities remaining in the peanut oil, realizing secondary fine filtration and improving the quality and purity of peanut oil.

[0030] 2. This invention features a pressure plate, a limiting block, a support column, and a base plate. The pressure plate, as the core pressing component, has an anti-slip protrusion structure at its bottom and employs progressive pressure adjustment. This ensures sufficient oil extraction from the peanut kernels while preventing excessive crushing. In existing technologies, after pressing, the pressed cake often remains inside the pressing chamber, requiring manual disassembly of the filter cylinder or manual removal of the cake from the bottom of the pressing chamber. This is not only cumbersome and time-consuming but also prone to causing the cake to scatter and become damaged, affecting subsequent recycling. In this device, after pressing, the base plate moves upward, smoothly removing the pressed peanut cake from the filter cylinder. Workers can quickly retrieve it via the side operating platform without disassembling any parts, significantly saving operation time and improving the convenience and efficiency of cake recycling. At the same time, it ensures the cake remains intact, facilitating subsequent recycling. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0043] The embodiments of the present invention will now be described.

[0044] A peanut oil production pressing and purification device, such as Figure 1 - Figure 9 As shown, the device includes a main body 1, a filter cartridge 8, a filter disc 13, and an oil filling platform 22. Multiple sets of main bodies 1 are installed on the upper end of the oil filling platform 22. The filter cartridge 8 is installed inside the main body 1, and the filter disc 13 is movably installed inside the main body 1.

[0045] A pressure plate 4 is movably installed inside the filter cylinder 8. Multiple sets of first filter holes 17 are opened on the side wall of the filter cylinder 8. Multiple sets of second filter holes 19 are opened on the outer wall of the filter disc 13. The diameter of the multiple sets of second filter holes 19 is smaller than the diameter of the multiple sets of first filter holes 17. A discharge pipe 15 is installed inside the main body 1 of the device, and the discharge pipe 15 is movably connected to the filter disc 13.

[0046] The main body 1 of the device has a support base 9 installed inside, and the support base 9 is connected to the filter cartridge 8. The support base 9 has a drive motor 10 installed inside, and the output end of the drive motor 10 has a drive shaft 11 installed. One end of the drive shaft 11 is equipped with multiple sets of connecting rods 12, and one end of each set of connecting rods 12 is connected to the filter disc 13. The drive motor 10 drives the drive shaft 11 to rotate, thereby driving the multiple sets of connecting rods 12 to rotate around the drive shaft 11 as the center, and thus driving the filter disc 13 to rotate.

[0047] Please see Figure 4 - Figure 7 The support base 9 has multiple sets of reserved holes 18, and the diameter of each set of reserved holes 18 is larger than the diameter of each set of first filter holes 17. The upper end of each set of first filter holes 17 is designed with a trumpet shape. After the peanut oil flows from the first filter holes 17 to the upper end of the support base 9, the peanut oil falls onto the upper end of the filter plate 13 through the multiple sets of reserved holes 18. The diameter of each set of reserved holes 18 is larger than the diameter of each set of first filter holes 17, which avoids impurities inside the peanut oil from clogging the reserved holes 18 and ensures smooth flow of the entire oil circuit. When the drive shaft 11 rotates, it generates a certain vibration. The support base 9 absorbs the vibration force, thereby shaking off some of the impurities adhering to the inner wall of the reserved holes 18, further preventing the reserved holes from clogging.

[0048] Please see Figure 4 - Figure 8 The filter disc 13 is funnel-shaped, and a limiting ring 14 is installed at the bottom of the filter disc 13. A reserved groove 16 is opened at the upper end of the discharge pipe 15, and the outer wall of the limiting ring 14 is movably connected to the inner wall of the reserved groove 16. Under the action of centrifugal force, it moves towards the center end of the filter disc 13. The filter disc 13 is funnel-shaped, and the impurities of the filter disc 13 will gradually gather to the center end of the filter disc 13. Then, through the discharge pipe 15 connected to the center end of the filter disc 13, under the dual action of gravity and centrifugal force, the impurities fall to the bottom end of the discharge pipe 15. The limiting ring 14 rotates inside the reserved groove 16 to improve the stability of the filter disc 13.

[0049] Please see Figure 1 The oil filling platform 22 is equipped with an impurity collection box, and one end of the discharge pipe 15 is connected to the impurity collection box. Impurities fall to the bottom of the discharge pipe 15 and then enter the impurity collection box. The impurity collection box adopts a sealed design to prevent impurities from scattering and polluting the production environment, and at the same time facilitates subsequent regular cleaning and recycling.

[0050] Please see Figure 1 - Figure 2 The main body 1 of the device is provided with an oil outlet pipe 20 at one end, and an oil outlet head 21 is installed at one end of the oil outlet pipe 20. When the oil outlet head 21 is activated, the peanut oil inside the main body 1 of the device is discharged through the oil outlet pipe 20.

[0051] Please see Figure 1 - Figure 6 A hydraulic cylinder 2 is mounted on the upper end of the oil filling platform 22, and a hydraulic device is connected to an external hydraulic pipe at one end of the hydraulic cylinder 2. A hydraulic rod 3 is installed inside the hydraulic cylinder 2. The hydraulic device introduces hydraulic oil into the hydraulic cylinder 2 through the hydraulic pipe. The hydraulic oil forms a stable pressure inside the hydraulic cylinder 2, which pushes the hydraulic rod 3 to move downward at a uniform speed in the vertical direction.

[0052] Please see Figure 6 One end of the hydraulic rod 3 is connected to the pressure plate 4, and the bottom of the pressure plate 4 is provided with anti-slip protrusions. The hydraulic rod 3 pushes the pressure plate 4 to move downward, and the pressure plate 4 squeezes the peanuts inside the filter cylinder 8. The bottom of the pressure plate 4 is provided with an anti-slip protrusion structure, which can increase the contact area with the peanut kernels and prevent the peanut kernels from sliding during the squeezing process.

[0053] Please see Figure 6 A base plate 6 is movably installed inside the filter cartridge 8, and the outer wall of the base plate 6 is movably connected to the inner wall of the filter cartridge 8. Multiple sets of support columns 5 are installed on the upper end of the base plate 6, and the inner wall of the pressure plate 4 is movably connected to the outer wall of the multiple sets of support columns 5. Limiting blocks 7 are installed on the upper end of each set of support columns 5, and rubber pads are provided at the bottom of each set of limiting blocks 7. When the pressure plate 4 moves upward, it moves to the area of ​​the multiple sets of limiting blocks 7 and comes into contact with them. As the pressure plate 4 continues to move upward, it drives the multiple sets of support columns 5 to move upward smoothly, thereby driving the base plate 6 to move upward as well.

[0054] Please see Figure 1 The oil filling platform 23 is equipped with an external screw conveyor, and an operating platform is provided on the side of the oil filling platform 23. The screw conveyor will smoothly and evenly introduce the cleaned and screened peanut kernels into the filter cylinder 8 from the feed port at the top of the filter cylinder 8. After the bottom plate 6 moves the pressed cake out of the filter cylinder 8, the staff can quickly recycle the pressed cake at the top of the bottom plate 6 with the help of the operating platform reserved on the side of the oil filling platform 23.

[0055] Please see Figure 1 A conveyor belt can be added to the upper end of the oil filling platform 23. The conveyor belt operates intermittently, and intermittently transports the oil drum to the lower end of the oil outlet 21.

[0056] The working principle of this invention is as follows: When the operator uses this device to produce peanut oil, the external screw conveyor smoothly and at a constant speed introduces the cleaned and screened peanut kernels into the filter cylinder 8 from the feed port at the top of the filter cylinder 8. Then, the external hydraulic device and drive motor 10 are started. The external hydraulic device introduces hydraulic oil into the hydraulic cylinder 2 through the hydraulic pipe. The hydraulic oil forms a stable pressure in the hydraulic cylinder 2, pushing the hydraulic rod 3 to move downward at a constant speed in the vertical direction, thereby pushing the pressure plate 4 to move downward. The pressure plate 4 squeezes the peanuts inside the filter cylinder 8. The bottom of the pressure plate 4 is provided with an anti-slip protrusion structure, which can increase the contact area with the peanut kernels and prevent the peanut kernels from sliding during the squeezing process. When the pressure plate 4 squeezes downward, it adopts a progressive pressure adjustment, gradually increasing from the initial low pressure to the rated working pressure. This can ensure that the oil in the peanut kernels is fully extracted, and prevent excessive pressure from causing excessive crushing of the peanut kernels and generating too many impurities that affect the purity of the oil.

[0057] Under the continuous squeezing action of the pressure plate 4, the oil inside the peanut kernel is gradually squeezed out. The peanut oil produced by the squeezing is slowly discharged from the outer end of the filter cylinder 8 through the first filter hole 17 on the side wall of the filter cylinder 8. The first filter hole 17 adopts a uniformly distributed fine pore design. The pore size is precisely controlled within the range that can intercept larger impurities such as peanut residue and coarse fiber, so as to achieve the initial filtration of peanut oil. The peanut oil after the initial filtration is clear and bright in color, effectively removing large particulate impurities that affect the quality of the oil, and preparing for the subsequent secondary filtration.

[0058] When peanut oil flows from the first filter hole 17 to the upper end of the support base 9, the peanut oil falls onto the upper end of the filter plate 13 through multiple sets of reserved holes 18. The diameter of the multiple sets of reserved holes 18 is larger than the diameter of the multiple sets of first filter holes 17, which avoids impurities inside the peanut oil from clogging the reserved holes 18, ensuring smooth flow of the entire oil circuit, avoiding equipment shutdown due to blockage, and improving production efficiency.

[0059] The drive motor 10 starts, driving the drive shaft 11 to rotate, which in turn drives multiple sets of connecting rods 12 to rotate around the drive shaft 11, thereby driving the filter disc 13 to rotate. Peanut oil falls onto the upper part of the rotating filter disc 13. Under the action of centrifugal force, the peanut oil and impurities are efficiently separated. The peanut oil with lower density is displaced on the outer wall of the filter disc 13 under the action of centrifugal force and falls quickly into the oil storage chamber inside the main body 1 of the device through the second filter hole 19 of the filter disc 13. The pore size of the second filter hole 19 is smaller than that of the first filter hole 17, which can further intercept the fine impurities remaining in the peanut oil, realize secondary fine filtration, and greatly improve the purity and quality of peanut oil.

[0060] Impurities inside the peanut oil (such as small peanut fragments and coarse fiber debris) have a higher density and are displaced towards the center of the filter plate 13 under the action of centrifugal force. The filter plate 13 is designed in a funnel shape, and the impurities will gradually gather at the center of the filter plate 13. Then, through the discharge pipe 15 connected to the center of the filter plate 13, they will fall steadily into the impurity collection box inside the oil filling platform 22 under the combined action of gravity and centrifugal force. The impurity collection box adopts a sealed design to prevent impurities from scattering and polluting the production environment, and at the same time facilitates subsequent regular cleaning and recycling.

[0061] After the peanuts inside the filter cylinder 8 are pressed, the hydraulic device uses hydraulic pipes to directionally return the hydraulic oil inside the hydraulic cylinder 2. During the return process, a slow-speed pressure control design is adopted to avoid the hydraulic oil returning too quickly and generating impact force, thus protecting core components such as the hydraulic cylinder 2 and hydraulic rod 3 and extending the service life of the device. As the hydraulic oil slowly returns, the hydraulic rod 3 moves upward smoothly under the pressure inside the hydraulic cylinder 2, thereby driving the pressure plate 4 to synchronously return upward.

[0062] When the pressure plate 4 moves to the area of ​​multiple sets of limiting blocks 7, the pressure plate 4 and the multiple sets of limiting blocks 7 come into contact. As the pressure plate 4 continues to move upward, it drives the multiple sets of support columns 5 to move upward smoothly, thereby driving the bottom plate 6 to move upward as well. This allows the peanut cake pressed and formed at the top of the bottom plate 6 to slowly move out of the filter cylinder 8. The cake has an intact overall shape, a firm texture, and is not easy to fall apart. The staff can use the operating platform reserved on the side of the oil filling platform 23 to quickly recover the cake at the top of the bottom plate 6 without disassembling the filter cylinder and other parts, which greatly saves the operation time and improves the convenience and efficiency of cake recovery. After the cake is recovered, the hydraulic device is restarted, which drives the bottom plate 6, support columns 5, limiting blocks 7 and pressure plate 4 to return to the initial working position in sequence, making full preparation for the next round of peanut pressing operation. The entire reset and recovery process is highly automated, effectively reducing manual intervention and further improving the continuity and efficiency of peanut oil production.

[0063] Workers place oil drums at the lower end of multiple sets of oil outlets 21. The multiple sets of oil outlets 21 pour peanut oil from the main body 1 of the device into the multiple sets of oil drums. A conveyor belt can be installed at the upper end of the oil filling platform 22 to transport and fill the oil drums.
