Processing device of high-quality strong-flavor pressed peanut oil

Abstract

This invention relates to the field of edible oil preparation technology, specifically to a processing apparatus for high-quality, fragrant pressed peanut oil. It includes a purification chamber with a top cover fixedly connected to its top. The purification chamber comprises a semi-circular cavity and a rectangular cavity. The rectangular cavity is used to generate centrifugal force by rotating the peanut oil. A movable separating plate for separating oil and impurities is slidably connected within the rectangular cavity. A scraper is slidably connected up and down on the side of the movable separating plate near the semi-circular cavity. After the rising scraper removes the gum material inside the movable separating plate, the gum material remains on the top inclined surface of the scraper. When the scraper rises to contact a limiting block, the bottom inclined surface of the limiting block slides against the top inclined surface of the scraper. As the scraper continues to rise, it drives the limiting block to slide towards the side near the semi-circular cavity, thereby preventing the scraper from slipping off the top of the movable separating plate. The bottom inclined surface of the limiting block scrapes away the gum material remaining on the top inclined surface of the scraper, preventing it from continuing to remain near the movable separating plate.

Description

Technical Field

[0001] This invention relates to the field of edible oil preparation technology, and more specifically, to a processing apparatus for high-quality, aromatic pressed peanut oil. Background Technology

[0002] With global population growth, rising living standards, and the booming food industry, the demand for edible oils continues to climb. According to market research data, the global edible oil market has shown steady growth in recent years, with different types of oils, such as soybean oil, rapeseed oil, peanut oil, and olive oil, enjoying a wide consumer base. Consumers are increasingly demanding in terms of edible oil quality, focusing not only on taste and flavor but also on nutritional value, health benefits, and safety. High-quality edible oils should be clear, odorless, and low in impurities, and rich in beneficial unsaturated fatty acids, vitamins, and other nutrients. This has prompted edible oil manufacturers to continuously improve their production processes and product quality to meet market demands.

[0003] In peanut oil processing, centrifugal filtration is required to separate the oil from solid impurities such as gums. The oil passes through the filtration mechanism to the collection mechanism, while larger solid impurities are trapped inside the filter structure. In current edible oil production and purification, processing plants need continuously operating purification equipment to improve efficiency. As operating time increases, the amount of solid impurities adhering to the inner wall of the filtration mechanism increases, affecting the efficiency of oil passing through the filter pores. In existing technologies, scrapers can only remove solid impurities adhering to the filtration mechanism, such as the inner wall of the filter plate. However, oil and gums have strong viscosity, and even after scraping, solid impurities remain inside the filter pores.

[0004] In view of this, we propose a processing device for high-quality, aromatic pressed peanut oil to improve the shortcomings of the existing technology. Summary of the Invention

[0005] This invention provides a processing device for high-quality, aromatic pressed peanut oil, which solves the problem that after long-term operation of existing peanut oil purification devices, the filter structure is prone to the adhesion of residual colloids and other solid impurities, and the solid impurities in the filter holes are difficult to remove by scraper.

[0006] To achieve the above objectives, the processing device for high-quality, aromatic pressed peanut oil includes a purification chamber with a top cover fixedly connected to the top. The purification chamber includes a semi-circular chamber and a rectangular chamber, and the rectangular chamber is used to rotate the edible oil to generate centrifugal force.

[0007] A hinged separating plate for separating grease and impurities is slidably connected inside the rectangular cavity. A scraper is slidably connected to the hinged separating plate on the side near the semicircular cavity. The sliding direction of the hinged separating plate is perpendicular to the scraper. A limiting block is provided below the purification cavity to prevent the scraper from slipping out of the rectangular cavity. The limiting block can scrape off impurities on the top of the scraper. When impurities increase on the side of the hinged separating plate near the semicircular cavity, the hinged separating plate slides to the side away from the semicircular cavity. The hinged separating plate coincides with the side wall of the purification cavity away from the semicircular cavity to clear the flow of the hinged separating plate.

[0008] In the above technical solution, the pressed crude oil to be refined is added into the purification chamber. The crude oil is driven to rotate in the semi-circular chamber to generate centrifugal force. When the crude oil rotates to the junction of the semi-circular chamber and the rectangular chamber, the crude oil moves tangentially towards the hinged separator plate. The oil in the crude oil passes through the hinged separator plate and finally flows out from the outlet to obtain the finished edible oil, while the gum in it is intercepted by the hinged separator plate on the side near the semi-circular chamber.

[0009] As grease continues to pass through the hinge separator, more impurities accumulate on the inside of the hinge separator, increasing the resistance as the grease flows through it. Since forces are reciprocal, the grease exerts a greater thrust on the hinge separator, causing it to slide away from the semi-circular cavity and clear the blockage.

[0010] Based on this, a mounting base is fixedly connected to the top of the top cover, and a main rod is rotatably connected to the center of the semi-circular cavity of the purification chamber. The top of the main rod is rotatably connected to the mounting base, and a first motor for driving the main rod is provided on the top of the mounting base.

[0011] The first motor includes a body and an output shaft. The body is fixedly connected to the mounting base, the output shaft is coaxially connected to the main rod, and a number of centrifugal blades are fixedly connected to the outer periphery of the main rod.

[0012] With this design, after the crude oil to be refined is added into the purification chamber, the power supply of the first motor is turned on. The first motor drives the main rod to rotate through the output shaft, and the centrifugal blades on the periphery of the main rod drive the crude oil in the purification chamber to rotate and generate centrifugal force.

[0013] In another technical solution, a number of second limiting bolts are fixedly connected to the top of the side wall of the purification chamber away from the semi-circular cavity, and a first limiting bolt is fixedly connected to the top of the loose-leaf separation plate at the corresponding position of the second limiting bolts. Each first limiting bolt has an adjusting rod fixedly connected to the side near the second limiting bolt, and the adjusting rod passes through the second limiting bolt.

[0014] Furthermore, along the sliding direction of the hinge separation plate, a plurality of filter holes are provided on the hinge separation plate, and a first spring is sleeved on the periphery of the adjusting rod between the first limiting bolt and the second limiting bolt.

[0015] Furthermore, the adjusting rod is fixedly connected to a first limiting cap at the end away from the first limiting bolt to prevent the loose-leaf separation plate from slipping off the second limiting bolt. The first limiting cap is located on the side of the second limiting bolt away from the loose-leaf separation plate. A number of ejector pins are fixedly connected to the inner wall of the purification chamber on the side facing the loose-leaf separation plate. The ejector pins are parallel to the sliding direction of the loose-leaf separation plate. When the filter hole coincides with the ejector pin, the outer peripheral surface of the ejector pin slides and fits against the inner peripheral surface of the filter hole.

[0016] In this technical solution, when the amount of solid impurities such as glue adhering to the inner surface of the leaf separator increases, some of the glue enters the filter holes, reducing the efficiency of the edible oil passing through the leaf separator and increasing the resistance of the leaf separator to the edible oil. Correspondingly, the pushing force of the edible oil on the leaf separator as it flows through the filter holes also increases. Under the action of the increased pushing force, the leaf separator moves closer to the side of the second limiting bolt. When the ejector pin is inserted into the filter hole, it pushes out the impurities blocking the filter hole. During this process, as the distance between the first and second limiting bolts decreases, the first spring is compressed and stores elastic potential energy.

[0017] In addition, racks are fixedly connected to the two ends of the scraper that are far apart. In the vertical direction, the racks are slidably connected to the side wall of the purification chamber, and in the horizontal direction, the relative position of the racks and the purification chamber is fixed.

[0018] Furthermore, a gear is rotatably connected to the side wall of the purification chamber, and a second motor for driving the gear is provided on the outer side wall of the purification chamber. The gear meshes with a rack, and the output shaft of the second motor is coaxially connected to the gear.

[0019] As can be seen from the above scheme, when the ejector pin pushes the glue blocking the filter holes to the inside of the leaf separation plate, the power of the second motor is turned on to drive the gear to rotate. The gear converts the rotation drive of the second motor into the driving force of the rack moving in a straight line. Thus, the rack drives the scraper to rise, thereby scraping off the glue adhering to the inner surface of the leaf separation plate.

[0020] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows:

[0021] After the adhesive on the inside of the leaf separator is scraped off by the rising scraper, the adhesive remains on the top slope of the scraper. When the scraper rises to contact the limiting block, the bottom slope of the limiting block slides and adheres to the top slope of the scraper. As the scraper continues to rise, it drives the limiting block to slide closer to the semi-circular cavity, thus preventing the scraper from slipping off the top of the leaf separator. Conversely, the bottom slope of the limiting block scrapes off the adhesive remaining on the top slope of the scraper, preventing it from continuing to remain near the leaf separator. Because the top slope of the scraper is designed with a gradually decreasing height from near the leaf separator to away from it, the side of the scraper near the leaf separator forms a "pointed" structure, thus cleaning the adhesive from the inner surface of the leaf separator.

[0040] In peanut oil processing, centrifugal filtration is required to separate the oil from solid impurities such as gums. The oil passes through the filtration mechanism to the collection mechanism, while larger solid impurities are trapped inside the filter structure. In current edible oil production and purification, processing plants need continuously operating purification equipment to improve efficiency. As operating time increases, the amount of solid impurities adhering to the inner wall of the filtration mechanism increases, affecting the efficiency of oil passing through the filter pores. In existing technologies, scrapers can only remove solid impurities adhering to the filtration mechanism, such as the inner wall of the filter plate. However, oil and gums have strong viscosity, and even after scraping, solid impurities remain inside the filter pores.

[0041] Please see Figure 1 - Figure 3 To solve the above problems, the present invention aims to provide a processing device for high-quality, fragrant pressed peanut oil. The purification device includes a purification chamber 100, and a top cover 110 is fixedly connected to the top of the purification chamber 100. The purification chamber 100 includes a semi-circular cavity and a rectangular cavity. The rectangular cavity is used to make the peanut oil rotate to generate centrifugal force.

[0042] A hinged separating plate 300 for separating grease and impurities is slidably connected inside the rectangular cavity. A scraper 410 is slidably connected to the hinged separating plate 300 on the side near the semi-circular cavity. The sliding direction of the hinged separating plate 300 is perpendicular to the scraper 410. A limiting block 400 is provided below the purification cavity 100 to prevent the scraper 410 from slipping out of the rectangular cavity. The limiting block 400 can scrape off the impurities on the top of the scraper 410. When the impurities on the side of the hinged separating plate 300 near the semi-circular cavity increase, the hinged separating plate 300 slides to the side away from the semi-circular cavity. The hinged separating plate 300 overlaps with the side wall of the purification cavity 100 away from the semi-circular cavity to clear the flow of the hinged separating plate 300.

[0043] It should be disclosed that this application is used to separate oil and impurities in peanut oil. The impurities to be separated mainly refer to solid impurities such as gum, which have relatively high viscosity and a large density difference with oil. Under the action of centrifugal force, the two are easy to separate.

[0044] In the process of refining peanut oil, the pressed crude oil to be refined is added into the refining chamber 100. The crude oil is driven to rotate in the semi-circular chamber, generating centrifugal force. When the crude oil rotates to the junction of the semi-circular chamber and the rectangular chamber, the crude oil moves tangentially towards the hinged separator 300. The oil in the crude oil passes through the hinged separator 300 and finally flows out from the outlet to obtain the finished peanut oil. The gum in the crude oil is intercepted by the hinged separator 300 on the side near the semi-circular chamber, which is called the inner side.

[0045] As grease continues to pass through the hinge separation plate 300, more impurities accumulate on the inner side of the hinge separation plate 300, increasing the resistance when the grease flows through the hinge separation plate 300. Since forces are reciprocal, the thrust of the grease on the hinge separation plate 300 increases, causing the hinge separation plate 300 to slide away from the semi-circular cavity, thus clearing the blockage in the hinge separation plate 300.

[0046] Next, as Figure 4 As shown, the driving principle of the centrifugal force generated inside the purification chamber 100 of peanut oil is disclosed. The top of the top cover 110 is fixedly connected to the mounting base 111. The main rod 200 is rotatably connected to the center of the semi-circular cavity of the purification chamber 100. The top of the main rod 200 is rotatably connected to the mounting base 111. The top of the mounting base 111 is provided with a first motor 210 for driving the main rod 200.

[0047] The first motor 210 includes a body and an output shaft. The body is fixedly connected to the mounting base 111, and the output shaft is coaxially connected to the main rod 200. Several centrifugal blades 220 are fixedly connected to the outer periphery of the main rod 200.

[0048] In other words, after the crude oil to be refined is added into the purification chamber 100, the power supply of the first motor 210 is turned on. The first motor 210 drives the main rod 200 to rotate through the output shaft. The centrifugal blades 220 around the main rod 200 drive the crude oil in the purification chamber 100 to rotate and generate centrifugal force.

[0049] exist Figure 5 and Figure 6 In the purification chamber 100, a number of second limiting bolts 303 are fixedly connected to the top of the side wall away from the semi-circular cavity. The top of the hinge separation plate 300 is fixedly connected to a first limiting bolt 302 at the corresponding position of the second limiting bolts 303. Each first limiting bolt 302 is fixedly connected to an adjusting rod 304 on the side close to the second limiting bolt 303. The adjusting rod 304 passes through the second limiting bolt 303.

[0050] Furthermore, along the sliding direction of the hinge separation plate 300, a number of filter holes 301 are provided on the hinge separation plate 300, and a first spring 305 is sleeved on the periphery of the adjusting rod 304 between the first limiting bolt 302 and the second limiting bolt 303.

[0051] Furthermore, the adjusting rod 304 has a first limiting cap 306 fixedly connected to the end away from the first limiting bolt 302 to prevent the loose-leaf separation plate 300 from slipping off the second limiting bolt 303. The first limiting cap 306 is located on the side of the second limiting bolt 303 away from the loose-leaf separation plate 300. Several ejector pins 310 are fixedly connected to the inner wall of the purification chamber 100 on the side facing the loose-leaf separation plate 300. The ejector pins 310 are parallel to the sliding direction of the loose-leaf separation plate 300. When the filter hole 301 coincides with the ejector pin 310, the outer peripheral surface of the ejector pin 310 slides and fits against the inner peripheral surface of the filter hole 301.

[0052] It should be noted that when the amount of solid impurities such as glue adhering to the inner surface of the leaf separating plate 300 increases, some of the glue enters the filter hole 301, reducing the efficiency of peanut oil passing through the leaf separating plate 300 and increasing the resistance of the leaf separating plate 300 to the edible oil. Correspondingly, the pushing force of peanut oil on the leaf separating plate 300 when flowing through the filter hole 301 also increases. Under the action of the increased pushing force, the leaf separating plate 300 moves closer to the side of the second limiting bolt 303. When the ejector pin 310 is inserted into the filter hole 301, it pushes out the impurities blocking the filter hole 301. During this process, as the distance between the first limiting bolt 302 and the second limiting bolt 303 decreases, the first spring 305 is compressed and stores elastic potential energy.

[0053] Based on the above, please refer to Figure 7 and Figure 8 As shown in the figure, racks 420 are fixedly connected to the two ends of the scraper 410 that are far apart. In the vertical direction, racks 420 are slidably connected to the side wall of purification chamber 100. In the horizontal direction, the relative position of racks 420 and purification chamber 100 is fixed.

[0054] Furthermore, a gear 421 is rotatably connected to the side wall of the purification chamber 100, and a second motor 422 for driving the gear 421 is provided on the outer side wall of the purification chamber 100. The gear 421 meshes with the rack 420, and the output shaft of the second motor 422 is coaxially connected to the gear 421.

[0055] With the above design, when the ejector pin 310 pushes the glue blocking the filter hole 301 to the inside of the leaf separation plate 300, the power supply of the second motor 422 is turned on, causing it to drive the gear 421 to rotate. The gear 421 converts the rotation drive of the second motor 422 into the driving force of the rack 420 moving in a straight line. As a result, the rack 420 drives the scraper 410 to rise, thereby scraping off the glue adhering to the inner surface of the leaf separation plate 300.

[0056] Based on the above explanation, finally using Figure 9 Explain the function of the limit block 400 in this application:

[0057] A balance groove 433 is provided on the top of the top cover 110 along the sliding direction of the hinge separation plate 300. A balance rod is fixedly connected in the balance groove 433. A guide rod 430 is fixedly connected to the top of the limiting block 400. The guide rod 430 is slidably connected to the balance rod along the sliding direction of the hinge separation plate 300. A second limiting cap 431 is fixedly connected to the top of the top cover 110 at the end of the guide rod 430 away from the limiting block 400.

[0058] Preferably, a second spring 432 for driving the guide rod 430 to reset is sleeved around the balance bar. The bottom of the limiting block 400 and the bottom of the scraper 410 are both provided with inclined surfaces. When the top inclined surface of the scraper 410 contacts the bottom inclined surface of the limiting block 400, the two slide and fit together.

[0059] The improvement lies in that after the rising scraper 410 scrapes off the adhesive on the inner side of the leaf separator 300, the adhesive remains on the top inclined surface of the scraper 410. When the scraper 410 rises to contact the limiting block 400, the bottom inclined surface of the limiting block 400 slides and adheres to the top inclined surface of the scraper 410. As the scraper 410 continues to rise, the scraper 410 drives the limiting block 400 to slide towards the side closer to the semi-circular cavity, thereby preventing the scraper 410 from slipping off the top of the leaf separator 300. Conversely, the bottom inclined surface of the limiting block 400 will scrape off the adhesive remaining on the top inclined surface of the scraper 410, preventing it from continuing to remain near the leaf separator 300. Because the top slope of the scraper 410 is designed to gradually decrease in height from near the hinge separation plate 300 to away from the hinge separation plate 300, the side of the top of the scraper 410 near the hinge separation plate 300 has a "pointed" structure, which makes it easier to scrape off the adhesive on the inner surface of the hinge separation plate 300.

[0060] The working principle of this refining and purification device will be described in more detail below:

[0061] First, the crude oil to be refined and pressed is put into the purification chamber 100, and the first motor 210 is started. The first motor 210 drives the main rod 200 and the centrifugal blades 220 to rotate, causing the crude oil in the purification chamber 100 to rotate and generate centrifugal force.

[0062] After the rotating crude oil flows to the junction of the semi-circular cavity and the rectangular cavity of the purification chamber 100, it flows tangentially to the hinged plate 300. The oil passes through the filter holes 301 on the hinged plate 300 and flows out to form finished oil. Solid impurities such as gum are intercepted inside the hinged plate 300.

[0063] During continuous operation, impurities accumulate on the inner side of the leaf separation plate 300, and some impurities block the filter holes 301, increasing the resistance to grease flow. The thrust of the grease on the leaf separation plate 300 increases accordingly, pushing the leaf separation plate 300 to slide away from the semi-circular cavity, and simultaneously compressing the first spring 305 to store elastic potential energy.

[0064] During the sliding process of the loose-leaf separation plate 300, the ejector pin 310 on the inner wall of the purification chamber 100 is inserted into the corresponding filter hole 301, pushing out the impurities that are blocked inside the filter hole 301.

[0065] Next, the second motor 422 is started to drive the gear 421 to rotate. Through meshing transmission, the rack 420 moves vertically, which in turn drives the scraper 410 upward to scrape off the adhesive impurities attached to the inner surface of the hinge separation plate 300. When the scraper 410 slides upward to contact the limiting block 400, the inclined surfaces of the two slide against each other. The scraper 410 pushes the limiting block 400 to move, which not only restricts the scraper 410 from slipping off, but also uses the limiting block 400 to scrape off and clean the adhesive impurities remaining on the top of the scraper 410.

[0066] After the impurities are cleaned, the first spring 305 and the second spring 432 release their elastic potential energy in sequence, which drives the hinge separation plate 300 and the limit block 400 to reset. The device continuously cycles to complete the centrifugal refining and purification of peanut oil.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
