Description

Technical Field

[0001] The invention belongs to the technical field of soybean oil production, in particular to a soybean oil fractional pressing and filtering processing device and a use method thereof. Background Art

[0002] Soybean oil is a vegetable oil extracted from the seeds of soybean plants. It is one of the most commonly used edible oils at this stage. It has a wide range of uses and can be used in a variety of cooking methods, including frying and grilling. In addition, it is also associated with a variety of health benefits, especially for the heart, skin and bones. It is rich in fats that are beneficial to heart health, maintains bone health, is rich in fatty acids, promotes skin health and other advantages that are beneficial to the body. At this stage, for the production of soybean oil, the soybeans need to be fried and then the oil is extracted through a screw oil press.

[0003] After soybeans are concentrated through the pressing process to extract oil, the residue will be more densely concentrated into cake-like residues. At this time, if direct pressing is performed, the residue has stronger pressure resistance and it is difficult to squeeze out the oil inside. As a result, a large amount of oil is still locked inside the cake-like residues, so the pressing process needs to be improved. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: a soybean oil fractional pressing and filtering processing device, comprising: The upper surface of the container plate is evenly provided with pressing units, each pressing unit can perform the work of pressing soybean oil independently, and multiple groups of pressing work can meet the oil production demand at the same time; The pressing unit comprises: a processing vessel to provide space for the soybeans to be pressed; Isolation components for isolating processing containers; An oil receiving component is provided at the lower portion of the processing container and is used to receive the squeezed soybean oil; The processing container comprises: The coarse pressing cylinder has a filter screen plate at the bottom of the inner cavity through a groove, and a docking slot is opened at the right end of the inner wall of the coarse pressing cylinder. The coarse pressing cylinder is used to perform preliminary pressing of a large amount of soybean material, so the internal volume of soybean material is the largest and the oil production is the largest; The fine pressing cylinder is arranged at the right end of the outer surface of the coarse pressing cylinder. The middle part of the inner cavity of the fine pressing cylinder is rotatably connected to the centrifugal mesh cylinder through the annular groove. The fine pressing cylinder is used to further press the soybean material after the coarse pressing and squeeze out the soybean oil concentrated in the inner layer of the soybean material. A built-in rotating ring is provided, and control balls are evenly arranged in the inner cavity of the built-in rotating ring, and the outer surface of the control balls is rollingly connected to the side of the centrifugal net cylinder. There are two built-in rotating rings, and the outer surface of the built-in rotating ring is fixedly connected to the inner cavity of the fine pressing cylinder. The built-in rotating ring can drive the centrifugal net cylinder to rotate by rolling the control balls. Since the amount of soybean oil in the secondary pressing is small, the oil attached to the outer surface of the centrifugal net cylinder needs to be centrifugally rotated and thrown away to avoid a large amount of oil residue.

[0005] Furthermore, the pressing unit further comprises: The main pressurizing component is arranged on the left side of the processing container and is used to press the soybeans inside the coarse pressing cylinder; The fine pressurizing component is arranged on the right side of the processing container and is used to pressurize the soybean residue inside the fine pressing cylinder; Since there is more bean material inside the coarse pressing cylinder and it is stacked thickly, the pressure applied by the main press component will be greater than the pressure applied by the fine press component, so the pressurization work is carried out by screw propulsion.

[0006] The main pressurizing component includes: A threaded push cylinder, wherein a fixed connecting plate is provided at the bottom of the threaded push cylinder, and the lower surface of the fixed connecting plate is fixedly connected to the upper surface of the container plate; A threaded push rod, the outer surface of which is threadedly connected to the inner cavity of the threaded push cylinder; A counterweight push plate, wherein the axis center of the outer surface of the counterweight push plate is rotatably connected to the end of the threaded push rod away from the threaded push cylinder, and the outer surface of the counterweight push plate is slidably connected to the inner wall of the rough pressing cylinder.

[0007] Furthermore, the precision pressurizing component includes: A pressurizing push cylinder, the outer surface of which is fixedly connected to a stabilizing bottom plate, the lower surface of which is fixedly connected to the upper surface of the container plate; A pressurizing push rod, the outer surface of which is slidably connected to the inner cavity of the pressurizing push cylinder, the left end of which is fixedly connected to a secondary pressure plate, the outer surface of which is slidably connected to the inner wall of the fine squeezing cylinder.

[0008] Furthermore, the isolation component includes: A vertical casing, wherein the bottom of the inner wall of the vertical casing is sleeved with the right side of the outer surface of the coarse pressing cylinder; A fixed top cover, the lower surface of which is fixedly connected to the top of the outer surface of the vertical casing; A control push box, wherein the inner wall of the control push box is symmetrically provided with vertical traction rods, and the top ends of the vertical traction rods extend to the outside of the control push box; The isolation plug plate has an outer surface that is slidably connected to the inner wall of the vertical sleeve. The isolation plug plate is inserted into the docking slot to completely isolate the coarse pressing cylinder from the fine pressing cylinder, so that the bean materials on both sides can be pressurized differently.

[0009] Furthermore, the isolation plug-in board includes: A docking connector, wherein the bottom end of the docking connector is fixedly connected to the upper surface of the isolation plugboard, and the inner wall of the docking connector is plugged into the bottom end of the vertical traction outer surface; An inner filling block, the outer surface of which is fixedly connected to the axis of the inner wall of the isolation plugboard; A pressure-sensitive side plate, the outer surface of which extends to the outside of the isolation plate through a groove, and the inner cavity of the pressure-sensitive side plate is fixedly connected to the inner cavity of the inner filling block through a built-in connecting rod; The lower part of the outer surface of the isolation plug is provided with a sharp cut surface, and the outer surface of the sharp cut surface is complementary to the inner wall of the docking slot. The isolation plug can cut off the pressurized bean material column on the left side through the sharp cut surface at the lower part, so that the bean material on the right side can be squeezed for the second time separately.

[0010] Furthermore, the oil receiving component includes: An oil tank, the lower surface of which is fixedly connected to the upper surface of the container plate; A supporting spacer, wherein the lower surface of the supporting spacer is fixedly connected to the inner wall of the oil tank, and the top of the outer surface of the supporting spacer is fixedly connected to the right side of the outer surface of the coarse pressing cylinder; A main detector, the outer surface of which is fixedly connected to the left side of the outer surface of the oil tank, and the inner cavity of the main detector is evenly provided with long detection rods, and the long detection rods extend into the interior of the oil tank; Auxiliary detector, the outer surface of which is fixedly connected to the right side of the outer surface of the oil tank. Short detection rods are evenly arranged in the inner cavity of the auxiliary detector, and the short detection rods extend into the interior of the oil tank. The detectors on both sides can detect the dripping oil through the corresponding detection rods to determine the residue content in the oil and further detect whether the obtained oil is qualified; A drainage jacket, the bottom of which is fixedly connected to the right side of the upper surface of the oil tank, and the inner wall of which is sleeved with the outer surface of the fine pressing cylinder; The residue guide rail has a left side of its outer surface fixedly connected to the right side of the outer surface of the oil tank, and the bottom end of the residue guide rail extends to the bottom of the container plate. The soybean material that has undergone secondary pressing can hardly obtain oil by pressing, so it is determined to be residue and is used for feed processing and needs to be recycled. After the residue is discharged from the fine pressing cylinder, it will fall into the residue guide rail and be recycled after being crushed to obtain residue fines.

[0011] The beneficial effects of the present invention are as follows: 1. The device can perform two-stage pressing of soybeans. Since the soybean material inside the fine pressing cylinder is the blank cut from the soybean material that has undergone preliminary pressing, and the soybean material inside the fine pressing cylinder is shorter, the oil squeezed inside the fine pressing cylinder mostly comes from the oil locked in the soybean material inside the coarse pressing cylinder. When the pressurization method does not change, the soybeans processed by this device can significantly improve the oil yield, and the pressure demand for related pressurizing equipment will not be too large, thereby achieving the effect of reducing costs and increasing efficiency and improving the oil yield of soybeans.

[0012] 2. Since the oil production inside the fine pressing cylinder is less than that inside the coarse pressing cylinder, and the oil is easy to adhere to the holes of the centrifugal mesh cylinder, the cooled oil is easy to block the holes of the centrifugal mesh cylinder. Therefore, the centrifugal mesh cylinder cannot retain a lot of oil for a long time. The fine pressing cylinder is improved so that the centrifugal mesh cylinder can rotate centrifugally when filtering the oil, and the oil inside the mesh is thrown away, thereby reducing the effect of oil residue and avoiding the problem of mesh blockage.

[0013] 3. Since the soybeans inside the coarse pressing cylinder are not added to the fine pressing cylinder for pressing at one time, and from the working method, it can be seen that part of the soybeans inside the coarse pressing cylinder will be pressed multiple times by the main pressure component. Through multiple pressing, the problem of low oil yield caused by a large amount of oil remaining inside the soybeans in a single pressing is avoided.

[0014] 4. When the device is continuously performing the pressing work, its rough pressurization work and the fine pressurization work can be carried out simultaneously, thereby improving work efficiency. In order to avoid the problem of insufficient pressure applied by the pressurizing component, resulting in a decrease in oil yield, and also to avoid the problem of excessive pressure applied by the pressurizing component exceeding the carrying load of the processing container, the middle isolation plug plate is improved so that the isolation plug plate not only has the function of blocking the oil and cutting the soybean material, but also can ensure that the pressure values applied by the pressurizing components on both sides meet the standards through its pressure-sensitive side plates. In this way, while meeting production needs and avoiding the above-mentioned problems, the soybean material can enter the next production process in time, so that the work process has obvious nodes for the purpose of dividing the pressing process.

[0015] 5. The oil discharged from the pressing cylinder will eventually enter the oil tank below. Due to the different processing procedures of the pressing cylinders on both sides, support blocks are used to isolate the oil inside the oil tank. When the oil drips, it will contact the corresponding detection rod. The detection rod can detect whether the oil is of qualified quality and judge the residue content inside the oil. This ensures that the stored oil is qualified and can also prevent unqualified oil from contaminating the good quality oil inside the oil tank in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0019] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a soybean oil fractional pressing and filtering processing device, comprising: The container plate 6 has pressing units 7 evenly arranged on its upper surface. Each pressing unit 7 can perform a separate pressing operation on soybean oil. Multiple pressing operations can be performed simultaneously to meet oil production requirements. The pressing unit 7 comprises: A processing container 1 is used to provide a space for squeezing soybeans; An isolation component 2, used to isolate the processing container 1; The oil receiving component 3 is provided at the lower part of the processing container 1 and is used to receive the squeezed soybean oil; The processing container 1 includes: The coarse pressing cylinder 11 has a filter screen 14 cut into the bottom of its inner cavity, and a docking slot 12 is provided at the right end of its inner wall. The coarse pressing cylinder 11 is used to perform preliminary pressing on a large amount of soybean material, so it can hold the most soybean material and produce the most oil. The fine pressing cylinder 13 is arranged at the right end of the outer surface of the coarse pressing cylinder 11. The middle part of the inner cavity of the fine pressing cylinder 13 is rotatably connected to the centrifugal mesh cylinder 15 through the annular groove. The interior of the fine pressing cylinder 13 is used to further press the soybean material after the coarse pressing, and squeeze out the soybean oil concentrated in the inner layer of the soybean material; A built-in swivel 16 is provided, and control balls 17 are evenly arranged in the inner cavity of the built-in swivel 16, and the outer surface of the control balls 17 is rollingly connected to the side of the centrifugal net cylinder 15. There are two built-in swivels 16, and the outer surface of the built-in swivel 16 is fixedly connected to the inner cavity of the fine pressing cylinder 13. The built-in swivel 16 can drive the centrifugal net cylinder 15 to rotate by rolling the control balls 17. Since the amount of soybean oil in the secondary pressing is small, the oil attached to the outer surface of the centrifugal net cylinder 15 needs to be centrifugally rotated and thrown away to avoid a large amount of oil residue.

[0020] The pressing unit 7 also includes: The main pressurizing component 4 is provided on the left side of the processing container 1 and is used to press the soybeans inside the coarse pressing cylinder 11; The fine pressurizing component 5 is provided on the right side of the processing container 1 and is used to pressurize the soybean residue inside the fine pressing cylinder 13; Since there is more bean material inside the coarse pressing cylinder 11 and it is stacked thickly, the pressure applied by the main pressurizing component 4 will be greater than the pressure applied by the fine pressurizing component 5, so the pressurizing work is carried out by screw propulsion.

[0021] The main pressurizing component 4 includes: A threaded push cylinder 41 is provided with a fixed connecting plate 42 at the bottom thereof, and the lower surface of the fixed connecting plate 42 is fixedly connected to the upper surface of the container plate 6; A threaded push rod 43, the outer surface of which is threadedly connected to the inner cavity of the threaded push cylinder 41; The counterweight push plate 44 has an outer surface that is rotatably connected to the end of the threaded push rod 43 away from the threaded push cylinder 41 at its axis, and the outer surface of the counterweight push plate 44 is slidably connected to the inner wall of the coarse pressing cylinder 11 .

[0022] The fine pressurizing component 5 includes: A pressurizing push cylinder 51, the outer surface of which is fixedly connected to a stabilizing bottom plate 52, the lower surface of which is fixedly connected to the upper surface of the container plate 6; The pressurizing push rod 53, the outer surface of the pressurizing push rod 53 is slidably connected to the inner cavity of the pressurizing push cylinder 51, and the left end of the pressurizing push rod 53 is fixedly connected to the auxiliary pressure plate 54, and the outer surface of the auxiliary pressure plate 54 is slidably connected to the inner wall of the fine squeezing cylinder 13.

[0023] Before processing, first pull out the counterweight push plate 44 on the left side of the processing container 1, and the threaded push cylinder 41 drives the threaded push rod 43 to rotate counterclockwise. The threaded push rod 43 spirals to the left, driving the counterweight push plate 44 to be pulled out from the interior of the processing container 1. Then the isolation component 2 separates the coarse pressing cylinder 11 and the fine pressing cylinder 13, so that the processing container 1 is divided into two groups of containers, thereby completing the preparation work.

[0024] The flattened soybeans are filled into the left space of the processing container 1, and then the threaded push cylinder 41 twists the threaded push rod 43 clockwise, and the counterweight push plate 44 is slowly inserted into the interior of the coarse pressing cylinder 11 to squeeze the soybeans inside. As the squeezing force applied by the counterweight push plate 44 becomes greater and greater, the oil in the soybeans is continuously squeezed out. After preliminary screening by the filter plate 14 and filtering out the bean dregs, the oil enters the oil receiving component 3 below, completing the preliminary squeezing work.

[0025] After the initial squeezing of the soybeans is completed, they will be stacked into a nearly columnar material body. At this time, the main pressure component 4 will temporarily stop working, and the isolation component 2 will lift the isolation plug plate 25 upward through the control push box 23 on the top, and then the coarse squeezing cylinder 11 is connected with the fine squeezing cylinder 13. Then the counterweight push plate 44 will continue to push the columnar soybeans squeezed inside the coarse squeezing cylinder 11 to the right, so that the columnar soybean material body is inserted into the interior of the fine squeezing cylinder 13 until the right end of the columnar soybean material body is flush with the right end outlet of the fine squeezing cylinder 13, and the main pressure component 4 will stop working again.

[0026] At this time, the isolation component 2 pushes the isolation plug 25 downward, and then the isolation plug 25 cuts the columnar soybean material through its sharp cutting surface 27. At this time, part of the soybean material is located inside the coarse pressing cylinder 11, and the other part is located inside the fine pressing cylinder 13. The sharp cutting surface 27 of the isolation plug 25 is inserted into the docking slot 12, and the coarse pressing cylinder 11 and the fine pressing cylinder 13 are completely separated again.

[0027] During the secondary squeezing operation, the main work is to squeeze the columnar soybean material inside the fine squeezing cylinder 13, but the blocking effect of the isolation component 2 allows the main pressure component 4 and the fine pressure component 5 to work synchronously. At this time, inside the coarse squeezing cylinder 11, the counterweight push plate 44 is first pulled out, and then the flattened soybeans that are vacant due to the cutoff of the isolation plug 25 are added to the left side of the inner wall of the coarse squeezing cylinder 11 to fill the inside of the coarse squeezing cylinder 11. Then the main pressure component 4 performs the preliminary squeezing operation. At this time, the flattened soybeans and the soybean material that has been squeezed for the first time will be squeezed again. On the one hand, the residual oil inside the soybean material can be squeezed out, and on the other hand, the oil inside the flattened soybeans can be squeezed out. Oil, so that the flattened soybeans and the soybean material body are combined and stacked together to form a complete columnar soybean material body again; inside the fine pressing cylinder 13, the pressure push cylinder 51 on the right side pressurizes the inside of the pressure push rod 53 by pneumatic pressure. At this time, the left end of the pressure push rod 53 will slide relative to the right end, so that the left end of the pressure push rod 53 slides to the left, and the soybean material body cut off inside the fine pressing cylinder 13 is pressurized by pushing the auxiliary pressure plate 54. Since this part of the soybean material body is less, the oil locked inside the soybean material body is more easily squeezed out, thereby producing remaining squeezed oil, which enters the oil receiving component 3 below through the mesh of the centrifugal net cylinder 15.

[0028] After the main pressure component 4 and the fine pressure component 5 have finished working synchronously, the isolation plug 25 is lifted up again, and then the fine pressure component 5 pulls out the auxiliary pressure plate 54 from the inside of the fine pressing cylinder 13. At this time, the main pressure component 4 continues to push the soybean material inside the coarse pressing cylinder 11 into the inside of the fine pressing cylinder 13. The soybean material on the left will push the soybean material inside the fine pressing cylinder 13 out of the inside of the fine pressing cylinder 13, and thus fall onto the residue guide rail 38, thereby realizing the discharge of soybean residue. Subsequently, the isolation component 2 pushes the isolation plug 25 downward again to cut off the soybean material on the left, thereby achieving the effect of replenishing the soybean material inside the fine pressing cylinder 13, and then the above-mentioned pressing work is performed again to complete the continuous pressing of soybeans.

[0029] Example 2, please refer to Figures 1-10 The present invention provides a technical solution: Based on embodiment 1, the isolation component 2 includes: A vertical casing 21, the bottom of the inner wall of the vertical casing 21 is sleeved with the right side of the outer surface of the coarse pressing cylinder 11; A fixed top cover 22, the lower surface of which is fixedly connected to the top of the outer surface of the vertical casing 21; A control push box 23, wherein vertical traction rods 24 are symmetrically provided on the inner wall of the control push box 23, and the top ends of the vertical traction rods 24 extend to the outside of the control push box 23; The isolation plug plate 25, the outer surface of the isolation plug plate 25 is slidably connected to the inner wall of the vertical sleeve 21, and the isolation plug plate 25 is inserted into the docking slot 12, which can completely isolate the coarse pressing cylinder 11 from the fine pressing cylinder 13, so that the bean materials on both sides can be pressurized differently.

[0030] The isolation board 25 includes: The butt joint 26 has its bottom end fixedly connected to the upper surface of the isolation plug plate 25, and its inner wall is plugged into the bottom end of the vertical traction outer surface; An inner filling block 28, the outer surface of the inner filling block 28 is fixedly connected to the axis of the inner wall of the isolation plug plate 25; The pressure-sensing side plate 29 has its outer surface extended to the outside of the isolation plate 25 through a slot, and the inner cavity of the pressure-sensing side plate 29 is fixedly connected to the inner cavity of the inner filling block 28 through a built-in connecting rod 210; A sharp cut surface 27 is provided on the lower portion of the outer surface of the isolation plug 25, and the outer surface of the sharp cut surface 27 is complementary to the inner wall of the docking slot 12. The isolation plug 25 can cut off the pressurized bean material column on the left side through the sharp cut surface 27 at the lower portion, so that the bean material on the right side can be squeezed a second time separately.

[0031] The oil receiving component 3 includes: The oil tank 31 has a lower surface fixedly connected to the upper surface of the container plate 6; A support block 32, the lower surface of which is fixedly connected to the inner wall of the oil tank 31, and the top of which is fixedly connected to the right side of the outer surface of the coarse pressing cylinder 11; The main detector 33 has an outer surface fixedly connected to the left side of the outer surface of the oil tank 31. Long detection rods 34 are evenly arranged in the inner cavity of the main detector 33, and the long detection rods 34 extend into the interior of the oil tank 31. Auxiliary detector 35, the outer surface of which is fixedly connected to the right side of the outer surface of the oil tank 31. Short detection rods 36 are evenly arranged in the inner cavity of the auxiliary detector 35, and the short detection rods 36 extend into the interior of the oil tank 31. The detectors on both sides can detect the dripping oil through the corresponding detection rods to determine the residue content in the oil and further determine whether the obtained oil is qualified. The drainage jacket 37 has its bottom fixedly connected to the right side of the upper surface of the oil tank 31, and its inner wall is sleeved with the outer surface of the fine pressing cylinder 13; The residue guide rail 38 has a left side on its outer surface fixedly connected to the right side on its outer surface of the oil tank 31. The bottom end of the residue guide rail 38 extends to the bottom of the container plate 6. The soybean material after secondary pressing can hardly obtain oil by pressing, so it is judged as residue and used for feed processing. It needs to be recycled. After the residue is discharged from the inside of the fine pressing cylinder 13, it will fall into the inside of the residue guide rail 38 and be recycled after being crushed to obtain residue fines.

[0032] When squeezing the soybean material inside the fine pressing cylinder 13, the built-in rotating rings 16 on both sides of the fine pressing cylinder 13 will drive the centrifugal screen cylinder 15 to rotate by twisting the control balls 17. At this time, the oil attached to the mesh of the centrifugal screen cylinder 15 will be thrown away under the centrifugal action. However, the outside of the fine pressing cylinder 13 is covered with a drainage jacket 37, so the oil will enter the area on the right side of the oil tank 31 under the guidance of the drainage jacket 37.

[0033] After the isolation plug 25 is plugged into the docking slot 12, the coarse pressing cylinder 11 and the fine pressing cylinder 13 will be separated, thereby providing corresponding connecting plates for the pressure plates on both sides to realize the squeezing action of the soybean material body. An internal filling block 28 is provided at the axis of the isolation plug 25 to ensure the structural strength of the isolation plug 25 and prevent the problem of inward deformation due to the pressurization action on both sides. As the soybean material bodies on both sides are squeezed, the pressure of the soybean material body on the outer surface of the isolation plug 25 is continuously increasing, thereby continuously increasing the pressing force on the pressure-sensitive side plate 29. The pressure data collected by the pressure-sensitive side plate 29, when the pressure indication inside the squeezing cylinder meets the standard, represents that the squeezing work here is completed, and the next step of the process is carried out.

[0034] The oil discharged from the pressing cylinder will eventually enter the oil tank 31 below. Due to the different processing procedures of the pressing cylinders on both sides, a support block 32 is used to isolate the oil inside the oil tank 31. When the oil drips, it will contact the corresponding detection rod. The detection rod can detect whether the quality of the oil is qualified and judge the residue content inside the oil. This ensures that the stored oil is qualified and can also promptly avoid the problem of unqualified oil contaminating the good quality oil inside the oil tank 31.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
