Description

Technical Field

[0001] The present application relates to the technical field of agricultural product production and processing, and in particular to a pressing device for producing vegetable oil. Background Art

[0002] Edible oil refers to animal or plant fats used in the process of making food. Oil pressing is the process of oil crops being divided into plant raw materials and animal raw materials according to their types. In the general production process, we mainly produce vegetable oil with plant raw materials, and plant raw materials are divided into legumes, seeds and hemp for pressing to extract oil. The specific methods of pressing vegetable oil are divided into cold pressing and hot pressing. The difference between cold pressing and hot pressing lies mainly in the production process and equipment, applicable oils, nutrients and flavors. The cold pressing method uses a low-temperature oil pressing process to press oils at a temperature below 60°C. The hot pressing method heats the oil before pressing to obtain a higher oil yield. The vegetable oil produced by the cold pressing process is light in color, and compared with hot pressing, it can retain nutrients such as vitamins, sterols, and carotenoids in the oil. Therefore, the cold pressing process for producing vegetable oil is still the main means of making edible oil.

[0003] However, a large amount of edible oil still remains in the residue cake after cold pressing. In order to reuse this part of edible oil, workers will manually add it back to the feeding port of the cold press. The density of the oil residue after pressing generally increases. Workers frequently add the oil residue back to the feeding port of the cold press manually using tools such as shovels, which is not only time-consuming and labor-intensive, but also inefficient.

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0031] like Figure 1 As shown, a pressing device for producing vegetable oil disclosed in the present application includes an oil press body 1, a receiving funnel 2 is provided at the residue outlet of the oil press body 1, the receiving funnel 2 is fixedly mounted on a support frame 3 through a funnel frame, a horizontal residue conveying mechanism 4 is provided at the lower port of the receiving funnel 2, and the horizontal residue conveying mechanism 4 is mounted on the support frame 3; a vertical residue conveying mechanism 5 is provided on the side of the horizontal residue conveying mechanism 4 close to the feeding port of the oil press body 1, the horizontal residue conveying mechanism 4 can horizontally convey the oil residue falling from the lower port of the receiving funnel 2 to the vertical residue conveying mechanism 5, and the vertical residue conveying mechanism 5 can continue to convey the received oil residue upward to the feeding port of the oil press body 1.

[0032] In the above embodiment, the oil press body 1 is a commonly used oil press device in the prior art, which can squeeze out edible oil from the original vegetable oil (such as pumpkin seeds, peanuts, sunflower seeds, rapeseed, etc.), and the oil residue produced by squeezing can be discharged from the residue outlet of the oil press body 1. Since the oil residue is produced by squeezing the oil press body 1, its density is usually relatively large, and the squeezed oil residue is mostly in the shape of a pancake, so the oil residue is also called a residue cake. It will consume a lot of physical strength for workers to add the dense oil residue to the feeding port of the oil press body 1 again with tools such as shovels. If the workers continue for a period of time, they will easily feel tired, and the efficiency of adding the oil residue will be affected.

[0033] When the pressing device of the present application is working, after the oil press body 1 performs the primary pressing on the original vegetable oil, the oil residue produced will be discharged from its residue outlet, and the receiving funnel 2 located below the residue outlet can collect these oil residues and guide them to be uniformly transported to the horizontal residue feeding mechanism 4, which can automatically move these oil residues in the horizontal direction toward the feeding port of the oil press body 1. When the horizontal position of the oil residue is similar to the horizontal position of the feeding port of the oil press body 1, the horizontal residue feeding mechanism 4 can transfer these oil residues to the vertical residue feeding mechanism 5, which will continue to lift these oil residues upward, so that the oil residues reach the vicinity of the feeding port of the oil press body 1 in the vertical direction, and then re-enter the feeding port of the oil press body 1, and reuse the oil press body 1 to perform secondary pressing on the oil residue, so that the edible oil in the oil is fully collected. Compared with the prior art, the pressing device of the present application is more convenient to use because it automatically completes the addition of oil residue, and the process of adding oil residue can be continuous, so it is more efficient than manual work.

[0034] Furthermore, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the horizontal slag conveying mechanism 4 includes a horizontally arranged first shell body 41, which is fixedly mounted on the support frame 3 through a bracket, and a first auger 42 is arranged in the first shell body 41, and the two ends of the rotating shaft of the first auger 42 are rotatably connected with the two ends of the axial direction of the first shell body 41 respectively; a first driving motor 43 is installed on the side of the first shell body 41 away from the vertical slag conveying mechanism 5, and the end of the rotating shaft of the first auger 42 adjacent to the first driving motor 43 passes through the side wall of the first shell body 41 on the same side and is fixedly connected with the output end of the first driving motor 43; a first feeding port 44 matching with the first feeding port 2 is arranged at a position on the upper side of the first shell body 41 corresponding to the lower port of the receiving funnel 2, and the two are fixedly connected; a first discharging port 45 is arranged on the lower side of the first shell body 41 away from the first feeding port 44.

[0035] In the above embodiment, the first feed port 44 of the first shell 41 is not only located opposite to the lower port of the receiving hopper 2, but also has the same shape. Thus, after the edge of the bottom feed port of the first shell 41 is welded to the edge of the lower port of the receiving hopper 2, the oil residue collected in the receiving hopper 2 can enter the first feed port 44 of the first shell 41 from its lower port, and then enter the interior of the first shell 41. One end of the first shell 41 is connected to the shell of the first drive motor 43, and the output end of the first drive motor 43 is fixedly connected to the end of the first auger 42 rotating shaft on the adjacent side, and both ends of the first auger 42 rotating shaft are rotatably connected to the first shell 41. Therefore, when the first drive motor 43 is working, the first auger 42 can be driven to rotate in the first shell 41, and the spiral blades on the rotating shaft of the first auger 42 are used to push the oil residue to the first discharge port 45 during the rotation of the first auger 42, and then discharged from the first discharge port 45 at the end of the first shell 41 to the vertical slag feeding mechanism 5. Since the auger has strong adaptability when conveying materials, it can be used to convey various granular, powdery, block and mixed materials, and has low requirements on the humidity and viscosity of the materials. Therefore, the present application utilizes the first auger 42 in the first shell 41 to transport oil residue.

[0036] Furthermore, if Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the vertical slag feeding mechanism 5 includes a vertically arranged stand 51, and a second shell 52 is fixedly installed on the stand 51 near the side of the oil press body 1, and a second auger 53 is arranged inside the second shell 52; the lower end of the rotating shaft of the second auger 53 passes through the lower end of the second shell 52 and is rotatably connected to the support base 54, and the support base 54 is fixedly installed on the stand 51; the upper end of the rotating shaft of the second auger 53 passes through the upper end of the second shell 52 and is fixedly connected to the output end of the second drive motor 55, and the shell of the second drive motor 55 is fixedly installed on the top of the stand 51; a second discharge port 56 inclined downward is provided on the upper end of the second shell 52 near the feeding port of the oil press body 1, and a second feed port 57 is provided on the lower end of the second shell 52 away from the oil press body 1, and the second feed port 57 is located directly below the first discharge port 45.

[0037] In the above embodiments, the stand 51 of the present application is a steel frame, the lower end of which is anchored to the ground by fixing bolts, so that the second housing 52 with a certain height and its internal components can obtain a stable support effect when connected to the stand 51. The upper and lower ends of the second auger 53 are rotatably connected to the upper and lower ends of the second housing 52, the lower end of the second auger 53 passes through the lower port of the second housing 52 and is rotatably connected to the support base 54, the upper end of the second auger 53 shaft passes through the upper end of the second housing 52 and is fixedly connected to the output end of the second drive motor 55, and the housing of the second drive motor 55 is fixed to the second housing 52, so when the second drive motor 55 is working, it can drive the second auger 53 to rotate in the second housing 52. The oil residue discharged from the first discharge port 45 by the horizontal residue conveying mechanism 4 will fall into the second feed port 57, and then enter the second shell 52. The rotating second auger 53 will push the oil residue upward in the second shell 52. When the oil residue reaches the second discharge port 56, it will automatically slide along the downwardly inclined second discharge port 56 toward the feed port of the oil press body 1. The vertical residue conveying mechanism 5 of the present application is the same as the horizontal residue conveying mechanism 4. It is not only simple to operate, but also can reduce pollution to the environment because the material is conveyed in a closed manner.

[0038] Furthermore, if Figure 2-Figure 4 As shown, a crushing assembly 6 is provided in the receiving funnel 2 below the residue outlet of the oil press body 1 , and the crushing assembly 6 can crush the oil residue discharged from the residue outlet of the oil press body 1 .

[0039] In the above embodiments, the oil residues produced after the original vegetable oil is initially pressed by the oil press body 1 are mostly residue cakes. If these large pieces of residue cakes are directly added to the oil press body 1, the edible oil in the residue cakes may still not be completely squeezed out. The crushing assembly 6 provided in the receiving funnel 2 of the present application can crush these oil residue cakes, so that the volume of the oil residue added to the oil press body 1 can be reduced, thereby improving the extraction rate of the residual edible oil in the oil residue during the secondary pressing process.

[0040] Furthermore, if Figure 2-Figure 4 As shown, the crushing assembly 6 includes two squeezing rollers 61 symmetrically arranged in the receiving funnel 2, and the slag outlet of the oil press body 1 is located above the squeezing area between the two squeezing rollers 61; both ends of the central rotating shaft of the squeezing roller 61 are rotatably connected to the side wall on the opposite side of the receiving funnel 2; a gear 62 is fixedly connected to the same end of the two squeezing rollers 61, and the two gears 62 are meshed with each other; one end of one of the squeezing rollers 61 away from the gear 62 is connected to the power unit 63.

[0041] In the above embodiment, the power unit 63 can rotate the gear 62 on the squeezing roller 61 through the squeezing roller 61 connected thereto, and the gear 62 will rotate synchronously with another squeezing roller 61 through another gear 62 meshing therewith, and the two rotating squeezing rollers 61 both rotate toward the middle area between them. The discharge port of the oil press body 1 is just above the middle area between the two squeezing rollers 61, so the oil residue discharged from the discharge port of the oil press body 1 will just fall between the two squeezing rollers 61, and the blades on the two squeezing rollers 61 moving in opposite directions can tear the residue cake into pieces, thereby reducing the volume of the residue cake, which is convenient for the subsequent oil press body 1 to fully squeeze the residue cake.

[0042] Furthermore, if Figure 3 As shown, the power unit 63 includes a first pulley 631, wherein one end of an extrusion roller 61 away from the gear 62 passes through the side wall of the receiving hopper 2 on the same side and is fixedly connected to the first pulley 631; one side of the first pulley 631 is connected to a second pulley 633 via a transmission belt 632, and the second pulley 633 is fixedly connected to the output end of the third drive motor 634, and the third drive motor 634 is fixedly mounted on the side wall of the receiving hopper 2 via a motor protection box 635.

[0043] In the above embodiment, when the third driving motor 634 is working, it can drive the first pulley 631 to rotate through the second pulley 633 and the conveyor belt 632. The first pulley 631 is connected to one of the squeezing rollers 61. Therefore, when the third driving motor 634 is working, it can provide power for the rotation of the two squeezing rollers 61, ensuring that the two squeezing rollers 61 have sufficient power to process the larger oil residue cake.

[0044] Furthermore, if Figure 2 , Figure 3 and Figure 5 As shown, the motor protection box 635 is fixedly installed on one of the corners of the receiving funnel 2 close to the oil press body 1, and the output end of the third drive motor 634 in the motor protection box 635 passes through the side wall of the receiving funnel 2 on the same side in the direction of the oil press body 1 and is fixedly connected to the first pulley 631, and the output end of the third drive motor 634 is rotatably connected to the side wall of the receiving funnel 2, and a heat dissipation hole 7 is provided at a position corresponding to the motor protection box 635 on the side wall of the receiving funnel 2 away from the squeezing roller 61.

[0045] In the above embodiments, the opening of the receiving hopper 2 of the present application is relatively large, which is not only convenient for collecting the oil discharged from the oil press body 1, but also convenient for workers to observe the transportation of the oil residue in the first shell 41 from the upper port of the receiving hopper 2. Since the gap between the receiving hopper 2 and the oil press body 1 is limited, and in order to facilitate the maintenance of the third drive motor 634, the motor protection shell used to install the third drive motor 634 is set in the receiving hopper 2 in the present application, so that the space inside the receiving hopper 2 can also be effectively utilized. The heat dissipation holes 7 on the receiving hopper 2 extend inwardly into the motor protection box 635, so that the third drive motor 634 can ensure that it has a better heat dissipation environment when working.

[0046] Furthermore, if Figure 2-Figure 4 As shown, a heating sleeve 8 is provided on the outer side of the first shell 41 close to one end of the second shell 52 , and a heating rod 9 is installed in the heating sleeve 8 .

[0047] In the above embodiments, although hot pressing will lose some nutrients compared to cold pressing, its oil extraction rate for oil in oil is higher. In actual production, hot pressing is also often used to extract oil from oil with low oil content. After the original plant oil has been cold pressed, the oil content in its oil residue is limited. At this time, if the cold pressing method is used for oil extraction, the extraction of oil from the oil residue may still be insufficient. Therefore, the present application sets a heating sleeve 8 on the first shell 41, and the heating rod 9 in the heating sleeve 8 heats the oil residue in the first shell 41 at the heating moment. This process is equivalent to the heating treatment of the oil when hot pressing is used for oil extraction. The subsequently heated oil residue can more fully squeeze out the residual oil in the oil residue when the oil press body is used for secondary pressing.

[0048] In actual production, after the oil residue begins to be heated, the edible oil discharged from the oil press body 1 should be collected again for subsequent classification, storage and sale.

[0049] Or if there is a need to produce edible oil by hot pressing at the beginning, the worker can add the original vegetable oil into the receiving funnel 2 at the beginning, and then start the heating rod 9 in the heating sleeve 8. The original vegetable oil will be heated by the heating rod 9 in the heating sleeve 8 during the process of moving from the first shell 41 to the second shell 52. When the heated oil enters the oil press body 1 through the vertical slag feeding mechanism 5 for oil pressing, the effect of hot pressing can be achieved. In this way, the oil pressing device of the present application can have more application scenarios.

[0050] The implementation principle of this embodiment is: when it is necessary to produce edible oil by cold pressing, the worker can first pour the original vegetable oil into the second feed port 57, and then start the second drive motor 55, and add the original vegetable oil to the feed port of the oil press body 1 through the second auger 53, and then the oil press body 1 will perform oil pressing operation on the original vegetable oil, and the obtained edible oil can be collected by special equipment or containers, and the generated oil residue will fall into the receiving funnel 2 after the slag discharge, and the two squeezing rollers 61 driven by the third drive motor 634 can process the oil residue to reduce its volume, and the processed oil residue will continue to fall into the first shell 41, and then re-enter the second shell 52 with the rotation of the first auger 42, and the second auger 53 in the second shell 52 will re-add the oil residue to the oil press body 1 for secondary oil pressing, and when the squeezed oil residue is qualified, the worker can collect the final oil residue in a packaging bag at the first discharge port 45.

[0051] When it is necessary to produce edible oil by hot pressing, workers first need to add the original vegetable oil into the receiving funnel 2, and then energize the heating rod 9 in the heating sleeve 8 on the first shell 41. The oil will be pushed by the first auger 42 in the first shell 41 and then heated after passing through the heating area of ​​the heating rod 9. After the heated oil falls from the first discharge port 45 to the second feed port 57 at the lower end of the second shell 52, the movement path of the oil is similar to that in the cold pressing method, which will not be repeated here.

[0052] When the cold pressing method needs to be combined with the hot pressing method, the initial pressing process of the original vegetable oil is the same as the initial pressing process of the original vegetable oil in the cold pressing method alone. The only difference is that when the oil residue needs to be pressed for the second time, the heating rod 9 in the heating sleeve 8 needs to be energized to heat the oil residue.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
