Description

Technical Field

[0001] This invention belongs to the field of edible oil processing technology, and in particular relates to an edible oil processing technology. Background Technology

[0002] During edible oil processing, especially in stages such as oilseed pressing, refining, heating, and transportation, substances like moisture, phospholipids, and saponins present in the raw materials easily generate large amounts of foam. This foam not only overflows processing containers, causing raw material loss and environmental pollution, but also poses safety risks and severely impacts the efficiency and product quality of subsequent processes such as distillation, deodorization, filtration, bottling, and storage. The presence of foam reduces the effective volume of the oil, interferes with the accuracy of liquid level control, and may lead to oxidative deterioration of the oil.

[0003] To eliminate foam, existing technologies employ various methods, commonly including static settling, chemical defoaming agents, and mechanical stirring or cooling defoaming. Static settling relies on gravity for natural defoaming, but this method is extremely time-consuming and cannot meet the efficiency requirements of continuous production, especially for viscous oils or microbubbles. While chemical defoaming agents can quickly break up foam, there is a risk of chemical residue, potentially affecting the flavor, safety, and purity of edible oils. Finally, mechanical stirring or cooling defoaming uses paddle agitation or built-in cooling pipes for cooling and defoaming. However, traditional stirring methods often have fixed structures and limited coverage, making it difficult to dynamically adapt to different foam distribution states. While built-in cooling pipes can cool and suppress foam, they are structurally complex, difficult to clean, and energy-intensive. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide an edible oil processing technology that can flexibly, efficiently, dynamically and without pollution actively break up foam inside the processing container.

[0005] An edible oil processing device includes a rotating rod and a fixed frame. A sliding sleeve is slidably connected to the rotating rod, and multiple umbrella rib rods are rotatably connected to the rotating rod. One end of multiple hinge rods is hinged to the sliding sleeve, and the other end of the multiple hinge rods is respectively hinged to the multiple umbrella rib rods. A rotating rod is rotatably connected to the fixed frame, and multiple crushing tips are fixedly connected to each umbrella rib rod.

[0006] The height of the multiple breaking tips gradually increases from the outside to the inside.

[0007] A metal woven mesh is fixedly connected between multiple umbrella ribs.

[0008] It also includes a connecting bracket connected to the sliding sleeve, on which a rubber cylinder is fixed.

[0009] The aforementioned edible oil processing equipment is used for the preparation of a soil remediation amendment, and the method includes the following steps:

[0010] Step 1: Install the mounting bracket onto the six-axis robotic arm through the threaded holes to ensure that the equipment can cover the entire oil tank area;

[0011] Step 2: The sliding sleeve moves down to retract the umbrella ribs and cause the rotating rod to rotate;

[0012] Step 3: Move the sliding sleeve upwards, and the hinge rod will push the umbrella rib rod to unfold;

[0013] Step 4: Move the fixed frame down until the rotating rod touches the bottom, and continue to push the sliding sleeve down to unfold the umbrella rib rod;

[0014] Step 5: The sliding sleeve moves upward to retract the umbrella rib rod, and the breaking tip presses the foam into the flexible cavity formed by the rubber cylinder;

[0015] Step Six: After defoaming, the crude oil is pumped into the refining tank, 0.1% phosphoric acid is added for degumming, then the free fatty acids are neutralized with alkali solution, and finally filtered to complete the processing. Attached Figure Description

[0026] An edible oil processing device includes a rotating rod 101 and a fixed frame 301. A sliding sleeve 104 is slidably connected to the rotating rod 101, and a plurality of umbrella rib rods 102 are rotatably connected to the rotating rod 101. One end of a plurality of hinge rods 105 is hinged to the sliding sleeve 104, and the other end of the plurality of hinge rods 105 is respectively hinged to the plurality of umbrella rib rods 102. The rotating rod 101 is rotatably connected to the fixed frame 301. A plurality of crushing tips 103 are fixedly connected to each umbrella rib rod 102. A first motor capable of driving the rotating rod 101 to rotate is fixedly connected to the fixed frame 301. A first electric push rod capable of driving the sliding sleeve 104 to slide is fixedly connected to the rotating rod 101. A storage battery A is fixedly connected to the rotating rod 101, and the storage battery A can provide power to the first electric push rod.

[0027] The fixed frame 301 is connected to a robotic arm that can carry the fixed frame 301 to move in multiple degrees of freedom. When it is necessary to remove the foam on the edible oil, the fixed frame 301 is moved downward, thereby moving the rotating rod 101 to a position where it can contact the edible oil. Then, the rotating rod 101 is rotated to drive the sliding sleeve 104 to rotate synchronously. At this time, the multiple umbrella-shaped rods 102 on the sliding sleeve 104 will break the foam on the surface or inside the edible oil, thereby achieving the effect of eliminating bubbles and providing a guarantee for subsequent distillation, transportation and storage operations.

[0028] During the continuous rotation of the sliding sleeve 104, which causes multiple umbrella rods 102 to break up bubbles, the operable sliding sleeve 104 slides up and down on the rotating rod 101. When the sliding sleeve 104 slides up and down, it drives one end of multiple hinge rods 105 to move synchronously, thereby causing the other ends of the multiple hinge rods 105 to push or pull the multiple umbrella rods 102 closer to or further away from each other, thus changing the slope of the multiple umbrella rods 102. This allows the multiple umbrella rods 102 to unfold or close in an umbrella-like structure, so that the multiple breaking tips 103 on the multiple umbrella rods 102 can contact the foam at different angles, applying different angles of breaking force to the bubbles, making the bubbles easier to break, and further improving the foam breaking effect during equipment operation. Subsequently, the fixed frame 301 moves continuously to eliminate foam at different positions in the container. That is, this equipment can contact the bubbles at different angles during the foam elimination process, efficiently removing foam from edible oil.

[0029] When the sliding sleeve 104 slides along the rotating rod 101, it pushes the umbrella rib rod 102 to change the tilt angle through the hinge rod 105, so as to realize the umbrella-shaped opening or closing. When it is opened, it can effectively expand the defoaming coverage area, while when it is closed, it can focus on the local foam-dense area for efficient defoaming.

[0030] During the defoaming process, multiple breaking tips 103, in conjunction with the unfolding of multiple umbrella-shaped rods 102 and the movement of the fixing frame 301, can form a three-dimensional piercing net for the foam, tearing the foam film from multiple directions, including horizontal, oblique, and vertical, thereby disrupting the surface tension balance and achieving a highly efficient defoaming effect.

[0031] The height of the multiple breaking tips 103 gradually increases from the outside to the inside.

[0032] Multiple breaking tips 103 at different heights can further provide different angles or different impact effects to the foam. In turn, during the foam removal process, the fixed frame 301 can be moved up and down to adjust the height of the rotating rod 101, so that the multiple breaking tips 103 can rub the foam surface. Since the heights of the multiple breaking tips 103 are different, the rubbing distance and range are also different. Combined with the movement of the fixed frame 301, the foam removal effect is further achieved in a comprehensive and efficient manner.

[0033] Furthermore, the progressively increasing height of the breaking tips 103 forms a stepped impact surface when they come into contact with the foam. The lower-positioned tips cut into the foam film at a shallow angle, mainly disrupting the surface tension, while the higher-positioned tips penetrate deep into the foam at a vertical angle, triggering a chain reaction of bubble rupture. When the fixed frame 301 moves up and down, the tips of different heights apply alternating shear and extrusion forces to the foam, simulating a "kneading" effect, accelerating the drainage of the liquid film and the merging of bubbles.

[0034] Meanwhile, the high-position sharp teeth "lift" the foam layer during the lifting process, exposing the bottom layer of bubbles; the low-position sharp teeth then cut in to achieve layered crushing. As the fixed frame 301 moves up and down, the cutting depth of the crushing tip 103 changes dynamically. The high-position sharp teeth prioritize treating the surface foam, while the low-position sharp teeth penetrate deep into the oil to remove newly formed bubbles.

[0035] A metal woven mesh 106 is fixedly connected between multiple umbrella ribs 102.

[0036] During the process of eliminating foam by rotating multiple umbrella rods 102, the metal woven mesh 106 can filter the edible oil. The liquid components in the edible oil can pass through the metal woven mesh 106, while the foam in the edible oil is blocked by the metal woven mesh 106 and remains on the outer surface of the metal woven mesh 106. That is, the metal woven mesh 106 can capture the foam by moving in conjunction with the fixing frame 301, so that when the multiple umbrella rods 102 rotate, they can directly contact a large amount of foam, thereby achieving an efficient foam elimination and breaking effect, further improving the defoaming efficiency. When the umbrella rods 102 rotate, the metal woven mesh 106 forms a dynamic filter surface, the oil flows through the mesh, while the foam is intercepted outside the mesh due to surface tension, creating a high-density impact environment for the subsequent breaking tip 103.

[0037] Furthermore, after rotating the rod 101 for a period of time, the fixing frame 301 can be continuously moved downward until the lowest end of the rod 101 contacts the bottom of the container. Then, the sliding sleeve 104 is continuously operated to slide downward on the rod 101. During this process, the sliding sleeve 104 will gradually unfold multiple umbrella rib rods 102 through the transmission of the hinge rod 105, thereby causing the metal woven mesh 106 to be tensioned and formed. Figure 6 As shown in the figure, the fixed frame 301 is then continuously moved upward to use the metal woven mesh 106 to retrieve all the foam in a vertical area inside the container until the foam is retrieved from the edible oil interface. The retrieval operation further eliminates the bubbles in the container and improves the defoaming effect.

[0038] It also includes a connecting bracket 203 connected to the sliding sleeve 104, on which a rubber cylinder 201 is fixed.

[0039] After the sliding sleeve 104 continues to slide downwards, causing the multiple umbrella ribs 102 to fully unfold and thus tighten the metal woven mesh 106, the rubber cylinder 201 can abut against the positions on the multiple umbrella ribs 102 where the metal woven mesh 106 is not installed. Then, when the fixing frame 301 is pulled upwards to retrieve the foam, the metal woven mesh 106 will form an inverted cone surface after being tightened, which will guide the foam towards the center by the metal woven mesh 106, thereby preventing the foam from overflowing from the outside of the metal woven mesh 106 during the upward lifting of the fixing frame 301. The rubber cylinder 201 can block the foam, preventing the foam from falling from the positions on the multiple umbrella ribs 102 where the metal woven mesh 106 is not installed, thus ensuring the foam retrieval effect.

[0040] After the foam is retrieved, it can be eliminated by blowing gas onto the foam surface. Then, the fixing frame 301 is moved to different positions and the retrieval operation is performed again. During the blowing of gas, the sliding sleeve 104 can be operated to gradually slide upward, so that multiple umbrella ribs 102 gradually move together and press the foam against the rubber cylinder 201, thereby actively pressing and eliminating the foam. The material of the rubber cylinder 201 allows the multiple umbrella ribs 102 to press and deform the rubber cylinder 201 after contact with it, thereby giving the multiple umbrella ribs 102 a larger movable space to further improve the active squeezing effect on the foam and improve the defoaming effect.

[0041] When the umbrella ribs retract, the crushing tip 103 presses the foam against the rubber cylinder, and the rubber deforms to form a "flexible concave cavity," which prolongs the time the foam is subjected to force and promotes the drainage of the liquid film. At the same time, the rubber stores elastic potential energy when it is compressed and deformed, and the energy is released instantly when the umbrella ribs rebound, generating high-frequency micro-vibrations that destroy the stability of the foam structure.

[0042] The rubber cylinder 201 has multiple threaded holes A202, and a rubber layer with protrusions of different shapes can be connected to the rubber cylinder 201 by screwing bolts into the multiple threaded holes A202.

[0043] The rubber layer with protrusions connected to the rubber cylinder 201 can work in conjunction with the squeezing effect of multiple umbrella ribs 102 to further break the foam efficiently, making the foam easier to puncture when it comes into contact with the smaller protrusions, thus achieving efficient breaking operation.

[0044] The connecting frame 203 is rotatably connected to the sliding sleeve 104. A second motor is fixedly connected to the sliding sleeve 104. A gear is fixedly connected to the output shaft of the second motor. A gear ring is fixedly connected to the connecting frame 203. The gear meshes with the gear ring. A storage battery B is fixedly connected to the sliding sleeve 104. The storage battery B supplies power to the second motor.

[0045] During the process of squeezing foam using multiple umbrella ribs 102 and rubber cylinder 201 to eliminate foam, the operable connecting frame 203 gradually rotates on the sliding sleeve 104, causing the rubber cylinder 201 to rotate along with the connecting frame 203. In this process, the combined effect of the parallel rotation of multiple umbrella ribs 102 can squeeze the foam and then slightly twist it, thereby further improving the foam elimination and breaking effect.

[0046] The fixing frame 301 has multiple fixing threaded holes 302.

[0047] The fixing frame 301 can be connected to a robotic arm with its own power source by screwing bolts into multiple fixing threaded holes 302, which facilitates the subsequent use of the robotic arm to drive the fixing frame 301 to move fully and thus perform a comprehensive foam removal operation on the cooking oil.

[0048] It also includes an auxiliary plate 401 connected to the fixing frame 301, and the auxiliary plate 401 has multiple threaded holes B402.

[0049] A blower capable of blowing hot air is connected to the auxiliary plate 401 by screwing bolts into multiple threaded holes B402. During the defoaming operation, the blower is started to continuously supply heat to the cooking oil, thus preventing the cooking oil from solidifying.

[0050] After the foam is lifted out of the oil, the continuously blowing hot air will gradually blow towards the foam, thereby blowing away and eliminating the foam, achieving the purpose of efficient foam removal.

[0051] It also includes a slider 403 fixed to the auxiliary plate 401. The auxiliary plate 401 is slidably connected to the fixed frame 301 via the slider 403. A second electric push rod capable of pushing the auxiliary plate 401 to slide is fixed to the fixed frame 301.

[0052] When hot air is blown, the auxiliary plate 401 can slide back and forth within a certain range on the fixed frame 301, thereby achieving the effect of adjusting the blowing range to facilitate comprehensive heating and avoid continuous heating in a single position, which would affect the quality of the edible oil.

[0053] When blowing to defoam, the blowing position can be changed by sliding the auxiliary plate 401, so that the foam can be blown by wind from different positions, which further facilitates the improvement of defoaming efficiency.

[0054] The aforementioned edible oil processing equipment is used for the preparation of a soil remediation amendment, and the method includes the following steps:

[0055] Step 1: Install the mounting bracket 301 onto the six-axis robotic arm through the fixing threaded hole 302 to ensure that the equipment can cover the entire oil tank area;

[0056] Step 2: The sliding sleeve 104 moves down to retract the umbrella rib rod 102 and cause the rotating rod 101 to rotate;

[0057] Step 3: Move the sliding sleeve 104 upward, and the hinge rod 105 will push the umbrella rib rod 102 to unfold;

[0058] Step 4: The fixing frame 301 moves down until the rotating rod 101 touches the bottom, and the sliding sleeve 104 continues to push down to unfold the umbrella rib rod 102;

[0059] Step 5: The sliding sleeve 104 moves upward to retract the umbrella rib rod 102, and the breaking tip 103 presses the foam into the flexible cavity formed by the rubber cylinder 201;

[0060] Step Six: After defoaming, the crude oil is pumped into the refining tank, 0.1% phosphoric acid is added for degumming, then the free fatty acids are neutralized with alkali solution, and finally filtered to complete the processing.
