DETAILED DESCRIPTION

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0034] Please refer to Figure 1-6 As a specific embodiment, the technical solution of the present invention is: a peeling device for oil pressing, comprising: The silo 2 includes a material leakage port 200; The drying unit 3 includes a first tube 32 and a drying assembly 31.

[0035] Specifically, the present application provides a peeling device for oil pressing, comprising an outer shell 1, a discharge port 215 is arranged at the bottom of one side of the outer shell 1; the discharge port 215 is connected to a first receiving hopper 11, the first receiving hopper 11 is connected to a kneading unit, and the kneaded material of the kneading unit can be collected in the first receiving hopper 11, a silo 2 is arranged above the outer shell 1, a leakage port 200 is arranged at the bottom of the silo 2, an air outlet end of an air pump 36 is connected to one end of a first tube 32, the other end of the first tube 32 is connected to a drying component 31, and the leakage port 200 is connected to a feed port on a side wall of the first tube 32. When working, by adding the oil crops to be peeled into the silo 2, the oil crops It can fall from the leakage port 200 into the first tube 32, and at the same time the air pump 36 also works. The airflow flows through the first tube 32, thereby driving the oil crops entering the first tube 32 to flow into the drying component 31 for rapid drying treatment. The oil crops that have been quickly dried enter the rubbing unit for rubbing treatment. The epidermis of the oil crops after rapid drying loses water due to heat and becomes brittle, which is more conducive to rubbing and peeling. Therefore, it is more conducive to peeling by rubbing alone, especially for peanuts and rapeseed. The peeling rate can reach more than 98%, and the breakage rate can be controlled below 3%. Compared with the peeling method through friction and collision, it can more easily ensure the integrity of the oil crops and reduce losses.

[0036] Further, as a specific implementation, the specific structure of the drying component 31 is: Figure 2-Figure 8 , Fig.15 , Fig.16 The drying component 31 includes a coaxially arranged outer cylinder 310, one end of the outer cylinder 310 is sealed, and the other end is connected to a second material receiving hopper 34, the second material receiving hopper 34 is connected to a second tube 350, the other end of the second tube 350 is connected to an air pump 36, and a pipe opening 3200 connected to the first tube 32 is provided on the side wall of the outer cylinder 310.

[0037] Specifically, the drying component 31 is configured with an outer cylinder 310, one end of the outer cylinder 310 is closed, and the other end is connected to the second material receiving hopper 34, the first tube 32 is connected to the side wall of the outer cylinder 310, and the material in the first tube 32 enters the outer cylinder 310 and can enter the second material receiving hopper 34 after being heated. Entering the second material receiving hopper 34 is conducive to collecting the dried material, and the kneading unit is connected to the second material receiving hopper 34, so as to facilitate the dried material to enter the kneading unit for kneading. The side wall of the second material receiving hopper 34 is connected with a second tube 350, and the other end of the second tube 350 is connected to the air inlet end of the air pump 36. Through this arrangement, when the air pump 36 is working, it can suck the airflow in the second material receiving hopper 34 back into the first tube 32, so that the heat of the airflow and material in the second material receiving hopper 34 can be recycled, thereby improving the utilization rate of heat and reducing energy consumption.

[0038] Furthermore, an air hole 340 is provided on the side wall of the second receiving hopper 34 . By providing the air hole 340 , air can be replenished into the second receiving hopper 34 through the air hole 340 when the air pump 36 is pumping, thereby reducing the suction resistance of the air pump 36 .

[0039] Further, as a preferred embodiment, refer to Figure 2-Figure 7 , and also includes a dehumidification unit 35. The air inlet of the air pump 36 is connected to the air outlet of the dehumidification unit 35, and the air inlet of the dehumidification unit 35 is connected to the other end of the second tube 350. Through this arrangement, when the air pump 36 is working, the airflow in the second receiving hopper 34 can be sucked through the dehumidification unit 35 and then returned to the first tube 32. The moisture in the airflow is removed by the dehumidification unit 35 to ensure the dryness of the airflow, thereby ensuring the drying effect on the oil crops, thereby ensuring the peeling effect. The dehumidification unit 35 can adopt any device in the prior art that can initialize the high-temperature airflow. It is not limited here as long as it can meet the working needs. It is preferably dehumidified by adsorption dehumidification.

[0040] Further, as a specific implementation, the drying component 31 includes an inner cylinder 311 coaxially arranged with the outer cylinder 310, a heating element 313 is arranged in the inner cylinder 311, and the pipe mouth 3200 is connected to a reducing pipe 320 connected to the first pipe 32; the angle between the axis of the reducing pipe 320 and the axis of the inner cylinder 311 is an acute angle.

[0041] As a specific implementation method, refer to Figure 8 , Fig.15 , Fig.16The axis of the outer cylinder 310 is set at an acute angle to the vertical, the axis of the reduction tube 320 is set horizontally, the inner cylinder 311 and the outer cylinder 310 are coaxially arranged, the upper end of the outer cylinder 310 is sealed by a flange, a mounting hole is coaxially arranged in the middle area of ​​the flange, a second flange is arranged at the upper end of the inner cylinder 311, and the second flange is fixed on the flange after the end of the inner cylinder 311 penetrates into the mounting hole, wherein the vertical projection of the extended line of the axis of the reduction tube 320 on the flange is tangent to the vertical projection of a virtual cylindrical surface on the flange that is equal to the inner circumference of the outer cylinder 310 and the outer circumference of the inner cylinder 311, and by setting the reduction tube 320, after the air pump 36 pumps the airflow through the leakage port 200, it carries the oil crops into the reduction tube 320, and the flow rate of the airflow can be increased by the reduction tube 320, thereby The airflow carries the oil crops quickly into the outer cylinder 310, and after entering the outer cylinder 310, it is guided through the annular channel between the outer cylinder 310 and the inner cylinder 311. Due to the setting direction of the reducing tube 320, the material and the airflow can rotate at a high speed between the inner cylinder 311 and the outer cylinder 310, and flow from the upper end of the outer cylinder 310 to the lower end of the outer cylinder 310. Through this setting, the inner cylinder 311 is heated, and then the annular channel between the outer cylinder 310 and the inner cylinder 311 is heated. The rotating airflow and the material in the annular channel can exchange heat better, so that the material can be heated faster and more evenly, and the surface of the material is evenly heated, so that the surface of the material loses water and becomes brittle, and then after being kneaded by the kneading unit, the surface is more easily broken and separated from the embryo, which is more conducive to subsequent kneading and peeling.

[0042] Specifically, as a specific implementation, the length of the outer tube is 2 meters to 3 meters, the diameter is 30 cm to 50 cm, and the diameter of the inner tube 311 is 15 cm to 35 cm. By controlling the working power of the air pump 36, it is ensured that the time for the airflow to flow from the outer tube 310 to the outer tube 310 is 5 to 10 seconds. Generally, the heating temperature inside the outer tube 310 is 150 to 200 degrees Celsius. Through the heating time of 5 to 10 seconds, only the epidermis is dried and heated to make the epidermis lose water, and the heating effect on the inner layer of the embryo is not good. Therefore, the embryo loses less water and is not easy to break, so that the integrity of the embryo can be better maintained.

[0043] Further, as a preferred embodiment, refer to Figure 5 , Fig.16 The inner cylinder 311 is sealed at one end close to the second material receiving funnel, and the other end is connected to the first negative pressure pipe 33. The other end of the first negative pressure pipe 33 is connected to the first pipe 32. A vent hole 312 is provided on the side wall of the inner cylinder 311.

[0044] Specifically, one end of the first negative pressure tube 33 is connected to the end of the inner cylinder 311, and the other end is connected to the first tube 32. It can be understood that when the airflow in the reduced diameter tube 320 quickly flows into the inner cylinder 311 and the outer cylinder 310, a high-speed rotating airflow will be formed in the annular channel between the inner cylinder 311 and the outer cylinder 310, especially in a section of the inner cylinder 311 and the outer cylinder 310 close to the sealing end, the airflow rotation effect is better, and the rotating airflow drives the gas in the annular channel to flow at a high speed. Under the action of centrifugal force, the airflow moves in the direction close to the inner side wall of the outer cylinder 310, so that a negative pressure zone can be formed around the outer peripheral surface of the inner cylinder 311. The present application evenly arranges air holes 340 on the outer peripheral surface of the inner cylinder 311 close to the upper end, and sets a first negative pressure zone at the upper end of the inner cylinder 311. The first negative pressure tube 33 is connected to the first tube 32. Through this arrangement, when the device is working, the outer peripheral surface of the outer tube 310 and the interior of the inner tube 311 will be connected through the air vent 340, so that a certain negative pressure is formed in the inner tube 311, so that the gas in the first tube 32 is sucked into the inner tube 311 through the first negative pressure tube 33, and then heated by the heating element 313 in the inner tube 311, and then flows out of the inner tube 311 through the air vent 340, and then mixes with the rotating airflow. Through this arrangement, a better heat exchange effect can be achieved, and the heat in the inner tube 311 can be discharged in time for heating. On the one hand, it can improve the heating efficiency and the uniformity of heating. On the other hand, it can also avoid the high temperature problem in the inner tube 311 and increase the service life of the inner tube 311.

[0045] Specifically, the heating element 313 is preferably an electric heating element 313, such as a silicon carbon rod, a silicon molybdenum rod, etc.

[0046] Further, refer to Fig.16 As a preferred embodiment, a plurality of heating elements 313 are provided, and the plurality of heating elements 313 are evenly spaced around the axis of the inner cylinder 311 , and one end of the first negative pressure tube 33 connected to the inner cylinder 311 is coaxially arranged with the inner cylinder 311 .

[0047] Specifically, the heating element 313 is preferably a rod structure, which can be extended along the length direction of the outer cylinder 310. The vents 312 are preferably evenly spaced around the axis of the inner cylinder 311. The end of the first negative pressure tube 33 connected to the inner cylinder 311 is coaxially arranged with the inner cylinder 311. Through this arrangement, when the airflow flows from the first negative pressure tube 33 into the central area of ​​the inner cylinder 311, under the suction effect of the negative pressure on the outer peripheral surface of the inner cylinder 311, the airflow flows from the center to the surroundings and passes through the heating element 313, thereby better taking away the heat generated by the heating element 313 and achieving a better heating effect.

[0048] Further, as a preferred embodiment, in order to further ensure the uniformity of heating the material, refer to Figure 5 , Fig.15 , Fig.17 The leakage port 200 is connected to a material distribution unit 21, which includes a material distribution barrel 213, a material distribution column 210 rotatably arranged in the material distribution barrel 213, and a motor 211 drivingly connected to the material distribution column 210. The material distribution barrel 213 includes a leakage port 200 and a discharge port 215 arranged opposite to each other, and the material distribution column 210 is provided with a groove 212 corresponding to the leakage port 200 and the discharge port 215. Specifically, as a specific implementation method, the axis of the material distribution barrel 213 is horizontally arranged, the silo 2 includes a silo 2 bottom, a material leakage port 200 is arranged on the silo 2 bottom, the silo 2 bottom is connected to the material distribution barrel 213 through a conical funnel-shaped material guide barrel, a material distribution port 214 is arranged on the upper side wall of the material distribution barrel 213, and a material discharge port 215 is arranged on the lower side wall, and the material discharge port 215 is communicated with the feed port on the first tube 32. The material distribution column 210 is rotatably arranged in the material distribution barrel 213. When working, the material in the silo 2 flows downward through the material leakage port 200, and is driven and connected by the motor 211. The material distribution column 210 A plurality of grooves 212 are evenly spaced on the outer surface thereof. When the motor 211 drives the material distribution column 210 to rotate, the grooves 212 can pass through the material distribution port 214 and the discharge port 215 in sequence. When the grooves 212 pass through the material distribution port 214, the material will enter the grooves 212, and then fall into the first tube 32 under the action of gravity as it rotates to the discharge port 215 below, thereby achieving the purpose of material distribution. In this way, the effect of uniform material distribution can be achieved, thereby ensuring that the material is evenly dried by the drying component 31, ensuring the consistency of material drying, and thus ensuring the uniformity of drying.

[0049] Furthermore, in some embodiments, a temperature sensor is provided between the inner cylinder 311 and the outer cylinder 310 to obtain the temperature between the inner cylinder 311 and the outer cylinder 310, and the heating power of the air pump 36 and the rotation speed of the motor 211 are controlled according to the temperature between the inner cylinder 311 and the outer cylinder 310. The higher the temperature between the inner cylinder 311 and the outer cylinder 310, the higher the working power of the air pump 36, the faster the rotation speed of the motor 211, and the higher the material conveying speed.

[0050] Embodiment 2 The technical solution of the present invention is: a peeling device for oil pressing processing, based on the first embodiment, the difference from the first embodiment is that Figure 9-Figure 14 The kneading unit includes an inclined material guide plate 44 and a kneading assembly arranged above the material guide plate 44. The kneading assembly includes two rotating rollers 430 arranged at intervals and a belt body 43 wound around the rotating rollers 430. The belt body 43 is configured to be able to reciprocate along the axial direction of the rotating rollers 430. The upper end of the material guide plate 44 is connected to the drying unit 3.

[0051] Specifically, refer to Figure 5-Figure 7The kneading unit includes an inclined guide plate 44, and support beams 440 are arranged at intervals below the guide plate 44. Both ends of the support beams 440 are connected to the outer shell 1 to provide support for the guide plate 44. The upper end of the guide plate 44 is connected to the second receiving hopper 34. The material dried by the drying component 31 is collected in the second receiving hopper 34. The bottom surface of the second receiving hopper 34 is inclined, which is conducive to the flow of materials to the guide plate 44. The guide plate 44 is inclined, which is conducive to the downward flow of materials. Both sides of the guide plate 44 are provided with enclosures to ensure that the material can flow downward from the upper surface of the guide plate 44. The axes of the two rotating rollers 430 are arranged along the width direction of the guide plate 44 and are arranged at intervals along the plate surface direction of the guide plate 44. The belt body 43 is preferably made of rubber. A layer of silicone is provided on the surface of the rubber material to ensure that the side in contact with the oil crops is flexible, thereby reducing the probability of damage to the oil crop blanks. During operation, one of the rotating rollers 430 can drive the belt body 43 to rotate, so that the belt body 43 close to the side of the guide plate 44 can move from top to bottom, thereby driving the oil crops to move from top to bottom between the belt body 43 and the upper surface of the guide plate 44. At the same time, the kneading component can also drive the belt body 43 to reciprocate along the axial direction of the rotating roller 430. During the reciprocating motion, the material between the belt body 43 and the guide plate 44 can be kneaded, thereby achieving a kneading and peeling effect while transporting the oil crops from top to bottom. Specifically, the specific driving method of the reciprocating motion of the belt body 43 along the axial direction of the rotating roller 430 is referred to below.

The other end of the second negative pressure pipe 61 can provide negative pressure suction force by connecting to a negative pressure suction device. The lower end of the suction funnel 62 is spaced apart from the guide plate 44. In this arrangement, the suction force is provided by the second negative pressure suction pipe. This creates negative pressure in the suction funnel 62 and generates suction force at the lower mouth, so that the surrounding air can be sucked into the suction funnel 62. At this time, the gas can flow into the suction funnel 62 through the through hole 441 below the guide plate 44, forming an airflow. After the oil crops are kneaded by the kneading component, they flow downward. When passing through the through hole 441, the lightweight outer skin will be sucked into the suction funnel 62 along with the airflow, and the blanks will be collected into the first receiving hopper 11 along with the guide plate 44, thereby achieving the purpose of cleaning the kneaded and separated epidermis.

After the connection, the length direction of the first support plate 46 is arranged parallel to the guide plate 44, and the second support plate 47 can move in the vertical direction through the guiding cooperation of the first guide rod 41 and the guide sleeve 402. A third guide hole 471 is arranged at both ends of the first guide plate. The first support plate 46 is provided with a third guide hole 471 that is connected to the two third guide holes 471. 71 guide cooperation first guide column 460, both ends of the first support plate 46 are also provided with a second guide hole 462 which is rotatably matched with the roller shaft of the rotating roller 430, the axis of the first guide column 460 is arranged in parallel with the second guide hole 462, and the installation support of the belt body 43 is achieved through this arrangement, and two groups of first support plates 46 and second support plates 47 are arranged on both sides of the belt body 43, wherein at least one first support sleeve 470 is arranged on the second support plate 47, and a linear drive member 45 is arranged on the first support sleeve 470, and the linear drive member 45 can be extended and retracted along the axial direction perpendicular to the rotating roller 430, thereby driving the first support plate 46 to reciprocate, driving the rotating roller 430 to reciprocate, thereby achieving the effect of driving the belt body 43 to reciprocate.

[0056] Specifically, the linear drive member 45 can be any one of a pneumatic telescopic rod and an electric telescopic rod.

[0057] Furthermore, the guiding cooperation between the first guide rod 41 and the guide sleeve 402 can enable the second support plate 47 to move in the vertical direction, thereby ensuring that the kneading unit can slide downward in the vertical direction under the action of gravity. Through this arrangement, when kneading the material, the gravity of the kneading unit can provide pressing pressure to the material below, thereby reducing the risk of oil crops being crushed due to excessive extrusion pressure.

[0058] Further, as a preferred embodiment, refer to Fig.13 A linear drive member 45 and / or a return elastic member 48 are arranged between the other first support plate 46 and the second support plate 47 .

[0059] Specifically, as a specific implementation, a linear drive member 45 is arranged between the first support plate 46 and the second support plate 47 on both sides of the belt body 43, and a return elastic member 48 is arranged between the first support plate 46 and the second support plate 47 on the other side. Preferably, the return elastic member 48 is a compression spring. With this arrangement, in the initial state, the compression spring is in an extended state, and the linear drive member 45 is in a contracted state. When working, refer to Fig.13 The linear driving member 45 is extended, and by pushing the first supporting plate 46, the two rotating rollers 430 and the belt body 43 move together to squeeze the compression spring. The linear driving member 45 is extended by a distance of 10 mm to 30 mm and then retracts. At this time, the rotating rollers 430 and the belt body 43 are pushed back to their original positions under the action of the rebound force of the compression spring, and this reciprocating motion kneading effect is achieved.

[0060] Furthermore, as another feasible implementation, linear drive members 45 can be set between the two groups of first support plates 46 and second support plates 47 on both sides of the belt body 43. The extension and retraction directions of the two linear drive members 45 are opposite, that is, one linear drive member 45 extends and the other linear drive member 45 contracts, and the reciprocating motion can also achieve the same effect.

[0061] Further, as a specific implementation, a tension roller 42 is also provided on the support frame 40 , and a tension elastic member 422 is provided between the tension roller 42 and the support frame 40 , and the tension elastic member 422 can provide elastic force to the tension roller 42 to move toward the belt body 43 .

[0062] Specifically, refer to Fig. 9 Along the axial direction of the rotating roller 430, two rigid plates 420 are arranged on the support frame 40 at intervals, and a second guide rod 421 is vertically guided on the rigid plate 420. The lower end of the second guide rod 421 is fixedly connected with a connecting piece, and the tension elastic member 422 includes two second compression springs respectively mounted on the two second guide rods 421, and the second compression spring is located between the connecting piece and the rigid plate 420. The two ends of the tension roller 42 are rotatably connected to the two connecting pieces. By setting the tension roller 42, tensioning force can be provided to the belt body 43 to ensure the kneading effect.

[0063] Further, as a preferred embodiment, refer to Fig.14The specific structure of the linear drive member 45 is as follows: it includes a body 450 that is detachably fixed on the first support sleeve 470, a columnar cavity 454 arranged in the body 450, an end cover 451 arranged at the end of the columnar cavity 454, and a piston 452 arranged in the columnar cavity 454. One end of the body 450 is provided with a guide channel 455 connected to the columnar cavity 454, and a driving rod 453 is guided in the guide channel 455. The inner circumference is provided with a first annular groove 4560, and the first annular groove 4560 is connected to a connecting pipe 456. The other end of the connecting pipe 456 is connected to the second negative pressure pipe 61. The driving rod 453 is guided in the guide channel 455. The outer circumferential surface of the movable rod 453 is provided with a second annular groove 4570 and a first port 4571 at intervals, and a second flow channel 457 communicating with the first port 4571 and the second annular groove 4570 is provided inside, a first flow channel 4520 is provided through the piston 452, and a third flow channel 458 communicating with the atmosphere is provided on the side wall of the columnar cavity 454, wherein the flow area of ​​the third flow channel 458 is greater than the flow area of ​​the first flow channel 4520, the flow area of ​​the first flow channel 4520 is smaller than the flow area of ​​the second flow channel 457, and the flow area of ​​the first flow channel 4520 is smaller than the flow area of ​​the third flow channel 458, with reference to Fig.14 In the initial state, the piston 452 is positioned against the end cover 451 under the elastic force of the return elastic member 48. When working, negative pressure is generated in the second negative pressure tube 61, thereby generating negative pressure in the connecting tube 456, thereby generating negative pressure in the first annular groove 4560, and thus generating negative pressure in the columnar cavity 454. Since the flow volume of the first flow channel 4520 is smaller than the flow area of ​​the second flow channel 457, a pressure difference is generated on both sides of the piston 452. Under the action of the pressure difference, the piston 452 can be driven to move, and the piston 452 pushes the drive rod 453 to move. The first support plate 46 is driven to move, thereby pushing the rotating roller 430 and the belt body 43 to move and squeeze the return elastic member 48. With the movement of the piston 452, the second annular groove 4570 and the first annular groove 4560 are gradually staggered and disconnected. The air pressure difference on both sides of the piston 452 is reduced by the connection of the first flow channel 4520. When the air pressure difference is less than the elastic force of the return elastic member 48, the flow area of ​​the first flow channel 4520 is pushed back under the action of the elastic force, so that the second annular groove is connected to the first annular groove 4560 again, and so on and so forth to achieve the driving purpose. Through this setting, the negative pressure drive of the second negative pressure tube 61 can be used to generate negative pressure in the second negative pressure tube 61 and then be linked, without the need to set up an additional control unit to control the operation of the linear drive member 45.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
