Description

Technical Field

[0001] This invention relates to enzymatic refining technology for soybean oil, and more specifically to an enzymatic refining apparatus for soybean oil production. Background Technology

[0002] Soybean oil is the world's most produced oil, widely used in the food industry and daily life. Traditional soybean oil refining processes mainly employ chemical and physical refining methods. Chemical refining requires the use of large amounts of alkali solutions for deacidification, generating significant amounts of wastewater, which not only pollutes the environment but also increases production costs. Physical refining, on the other hand, requires high-temperature conditions, which can easily lead to the loss of heat-sensitive nutrients in the oil, reducing its quality. In recent years, enzymatic refining technology has been increasingly applied to the soybean oil refining process. Enzymatic refining offers advantages such as mild reaction conditions, environmental friendliness, and the ability to retain the nutrients in the oil.

[0003] Chinese invention patent CN 117757566 B discloses a production apparatus and method for enzymatic refining of soybean oil, including a support leg and a refining cylinder. The top of the support leg is fixedly connected to the bottom of the refining cylinder, and a feed pipe is fixedly inserted through the top of the refining cylinder. A dispersing feed device is provided at one end of the feed pipe. The dispersing feed device includes a connecting plate, the bottom of which is fixedly connected to one end of the feed pipe. An electric reciprocating push rod is fixedly connected to the bottom of the connecting plate, and an intercepting plate is fixedly connected to the end of the electric reciprocating push rod away from the connecting plate. A connecting circular plate is fixedly connected to the inner wall of the feed pipe, and a feed inlet is opened at the top of the connecting circular plate. The bottom of the feed inlet is located on the displacement trajectory of the intercepting plate.

[0004] In the aforementioned application, the opening and closing of the feed inlet is mainly achieved by adjusting the position of the interceptor plate and the connecting circular plate, so that the soybeans stored in the feed pipe can be fed in a controlled manner. However, in actual application, the horizontally set interceptor plate is still directly below the feed inlet after it is opened, and some soybeans will fall directly onto its surface. This not only obstructs the feeding of soybeans, but also hinders the subsequent closure of the feed inlet. In addition, during the enzymatic preparation of soybeans, in order to improve the release rate of soybean oil, the soybeans are crushed first. However, uneven crushing during the crushing process can easily result in large soybean particles. In this application, a crushing roller is set to rotate along the surface of the sieve plate and crush the soybeans again. However, in actual application, when the crushing roller crushes the soybean particles, it can easily compact them into the inside of the sieve holes, resulting in clogging of the sieve plate. Summary of the Invention

[0005] The purpose of this invention is to provide an enzymatic refining apparatus for soybean oil production, thereby overcoming the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a production apparatus for enzymatic refining of soybean oil, comprising an enzyme reaction tank and an inlet pipe and an enzyme inlet pipe disposed thereon, wherein an oil discharge pipe is disposed at the bottom of the enzyme reaction tank, and a feed cylinder connected to the inside of the enzyme reaction tank is disposed at the top of the enzyme reaction tank, wherein a discharge hopper is disposed inside the feed cylinder, and the inside of the feed cylinder is divided into a storage chamber and a processing chamber by the discharge hopper, wherein a discharge port is disposed at the bottom of the discharge hopper, and a sealing plate is disposed inside the discharge hopper to seal the discharge port, wherein multiple sets of anti-blocking rods are disposed at equal intervals in a circular shape at the bottom of the sealing plate;

When the rotating rod rotates and drives the pusher seat to rotate, the rubber curtain assists the soybean particles to move along the feeding ramp to the sieve plate.

[0012] Furthermore, the enzyme reaction vessel is provided with an outer shell, and two sets of crushing rollers are rotatably connected to the inner side of the shell. The crushing rollers are driven by a motor, and the motor drives the two sets of crushing rollers to rotate synchronously in opposite directions.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Example 1:

[0031] Please see Figures 1-4 An enzymatic refining apparatus for soybean oil includes an enzyme reaction tank 1 and an inlet pipe 101 and an enzyme inlet pipe 102 installed thereon. An oil drain pipe 103 is installed at the bottom of the enzyme reaction tank 1. A feed cylinder 2 connected to the inside of the enzyme reaction tank 1 is installed at the top of the enzyme reaction tank 1. A hopper 21 is installed inside the feed cylinder 2. The inside of the feed cylinder 2 is divided into a storage chamber 22 and a processing chamber 23 by the hopper 21. A discharge port 24 is installed at the bottom of the hopper 21. A sealing plate 25 is installed inside the hopper 21 to seal the discharge port 24. Multiple anti-blocking rods 26 are arranged in a circular shape at equal intervals at the bottom of the sealing plate 25.

[0032] It should be noted that the length of the anti-blocking rod 26 is greater than the length of the discharge port 24, so that when the sealing plate 25 moves upward to the set position to discharge material, the bottom part of the anti-blocking rod 26 is still partially left in the discharge port 24.

[0033] It should be further explained that during operation, the crushed soybean particles are fed into the feed cylinder 2, the enzyme preparation is transported into the enzyme reaction tank 1 through the enzyme inlet pipe 102, and the reaction water is transported into the enzyme reaction tank 1 through the water inlet pipe 101.

[0034] To ensure smooth discharge of crushed soybean particles from the storage chamber 22, a drive unit is installed on the hopper 21. The drive unit is used to open and close the discharge port 24 and drive the sealing plate 25 to rotate after the discharge port 24 is opened. The drive unit includes a bearing plate 3 installed on the top of the feed cylinder 2. A rotating sleeve 31 is rotatably connected to the top of the bearing plate 3. The rotating sleeve 31 is driven by a motor. A drive rod 32 is installed on the top of the sealing plate 25. Multiple sets of synchronization blocks 33 are equidistantly arranged on the outside of the drive rod 32. Several synchronization slots 34 that are adapted to the synchronization blocks 33 are equidistantly opened on the inner side of the rotating sleeve 31. An electric telescopic rod 35 is installed on the top of the bearing plate 3. A connecting plate 36 is installed on the top of the electric telescopic rod 35. The top of the drive rod 32 is rotatably connected to the connecting plate 36.

[0035] During operation, crushed soybean particles are fed into and stored in the storage chamber 22 on the feed cylinder 2. When feeding is required, the connecting plate 36 is driven to move upward by the electric telescopic rod 35. The movement of the connecting plate 36 drives the drive rod 32 to move upward, and the movement of the drive rod 32 drives the sealing plate 25 to move, so that the sealing plate 25 moves upward and separates from the inner wall of the feed hopper 21, allowing the soybean particles inside the storage chamber 22 to be discharged downward from the discharge port 24 at the bottom of the feed hopper 21.

[0036] After the sealing plate 25 moves upward to open the discharge port 24, the electric telescopic rod 35 continues to drive the drive rod 32 to move upward. The upward movement of the drive rod 32 drives the synchronous block 33 to move, so that the synchronous block 33 gradually approaches the synchronous groove 34 and embeds itself inside the synchronous groove 34. When the synchronous block 33 is completely embedded inside the synchronous groove 34, the electric telescopic rod 35 stops driving the drive rod 32 to move. At this time, the rotating sleeve 31 is driven by the motor to rotate, so that the rotating sleeve 31 drives the drive rod 32 to rotate. The rotation of the drive rod 32 drives the sealing plate 25 to rotate, and the rotation of the sealing plate 25 drives the anti-blocking rod 26 to rotate. When the anti-blocking rod 26 rotates, it agitates the soybeans inside the discharge port 24 and at the bottom of the hopper 21, so that the crushed soybean particles fall more smoothly and are less likely to block.

[0037] Example 2:

[0038] Please see Figure 2 , Figures 4-6 This embodiment provides a technical solution based on the above embodiments: an enzyme reaction vessel 1 is provided with a reprocessing unit, the reprocessing unit includes a re-screening plate 4 installed at the bottom of the inner wall of the feed cylinder 2, a rotating rod 41 is rotatably connected to the re-screening plate 4, a sieve 42 is rotatably connected to the outside of the rotating rod 41 at equal intervals, and a pusher seat 43 is rotatably connected to one side of the sieve 42.

[0039] After the soybean particles fall onto the double screen plate 4, the pusher seat 43 is driven to rotate by the rotating rod 41, so that the soybean particles on the double screen plate 4 can always be in motion, thereby enabling better screening and allowing soybean particles that meet the specifications to pass through the double screen plate 4 and fall to the bottom of the enzyme reaction tank 1.

[0040] It should be added that a feeding slope 44 is provided on the side of the pusher seat 43 away from the screening plate 42. The screening plate 42 is inclined downward at the end near the rotating rod 41. A support rod 45 is installed on the inner wall of the processing chamber 23. A rubber curtain 46 adapted to the feeding slope 44 is fixedly connected to the bottom of the support rod 45. The bottom of the rubber curtain 46 is in contact with the surface of the double screening plate 4. When the rotating rod 41 rotates and drives the pusher seat 43 to rotate, the rubber curtain 46 assists the soybean particles to move along the feeding slope 44 to the screening plate 42. That is, the pusher seat 43 will rotate relative to the rubber curtain 46 during the rotation. During the rotation of the pusher seat 43, there will be a lot of soybean particles on the feeding slope 44. When they move to contact the rubber curtain 46, the rubber curtain 46 will apply an upward pushing force to the soybeans, so that the soybeans on the feeding slope 44 can move upward and fall off the top of the feeding slope 44 onto the screening plate 42.

[0041] It should be further added that a discharge arc surface is also provided between the pusher seat 43 and the rotating rod 41. The position of the discharge arc surface corresponds to the rubber curtain 46. As the pusher seat 43 rotates, it can push the soybean particles near the rotating rod 41 outward. With the cooperation of the rubber curtain 46, it can be transported to the feeding inclined surface 44, so that the soybean particles falling on the double screen plate 4 can be fully screened and the dead corners are less likely to occur.

[0042] The enzyme reaction vessel 1 is provided with an outer shell 47. Two sets of crushing rollers 48 are rotatably connected to the inner side of the shell 47. The crushing rollers 48 are driven by a motor, and the motor drives the two sets of crushing rollers 48 to rotate synchronously in opposite directions. An inclined discharge section 49 is provided at the bottom of the shell 47, and the bottom end of the inclined discharge section 49 extends into the interior of the enzyme reaction vessel 1.

[0043] It should be noted that both sets of crushing rollers 48 are equipped with transmission gears on their exteriors, and the two transmission gears mesh with each other. The motor is connected to one of the transmission gears and drives it to rotate, so that the two sets of crushing rollers 48 can rotate synchronously in opposite directions to achieve further crushing of soybeans. The above driving method is existing technology and will not be described in detail here.

[0044] To ensure that the large soybean particles obtained from the screening plate 42 can be smoothly fed to the crushing roller 48 for further crushing, a feeding chamber 410 is provided at the bottom of the rotating rod 41, and an inlet 411 corresponding to the screening plate 42 is provided on the side of the rotating rod 41. The inlet 411 is connected to the feeding chamber 410. An inclined conveying pipe 412 is rotatably connected to the bottom of the rotating rod 41. The feeding end of the conveying pipe 412 extends into the machine casing 47 and corresponds to the two sets of crushing rollers 48.

[0045] During operation, the rotating rod 41 rotates and drives the pusher seat 43 to rotate. As the pusher seat 43 rotates, it can push the soybean particles that fall on the screen plate 4 to move, thereby accelerating the screening and falling of the soybean particles.

[0046] During the rotation of the pusher seat 43, some soybeans that do not have time to fall off the double screen plate 4 accumulate on its feeding inclined surface 44. When the pusher seat 43 rotates to the position of the rubber curtain 46, the soybean particles accumulated on the feeding inclined surface 44 move upward along the inclined surface under the push of the rubber curtain 46 and detach from it at the top position, thus falling onto the screening plate 42. The soybean particles falling onto the screening plate 42 roll downward along its inclined surface, and the soybean particles that meet the screening specifications will fall off the screening plate 42. The soybean particles are separated from the screen holes, while the large soybean particles roll along their surface and enter the feeding chamber 410 through the inlet 411. The soybean particles that have entered the chamber will enter the casing 47 through the conveying pipe 412 and fall between the two sets of crushing rollers 48. At this time, the two sets of crushing rollers 48 are in a rotating working state. After the soybean particles fall between them, they will be crushed again by the two sets of crushing rollers 48. The crushed soybean particles will be discharged from the inclined discharge section 49 at the bottom of the casing 47 and fall to the bottom of the enzyme reaction tank 1.

[0047] Example 3:

[0048] Please see Figures 4-5 This embodiment provides a technical solution based on the above embodiments: a square groove 5 is provided at the top inside the rotating rod 41, a block 51 is slidably connected to the inner side of the square groove 5, a synchronizing rod 52 is fixedly connected between the block 51 and the sealing plate 25, and the synchronizing rod 52 is slidably connected to the inner side of the rotating rod 41.

[0049] It should be added that the distance between the synchronization block 33 and the synchronization slot 34 is matched with the depth of the square slot 5.

[0050] During operation, when the sealing plate 25 moves upward to open the discharge port 24, the synchronizing rod 52 moves synchronously, causing the block 51 to slide along the inside of the square groove 5. When the driving rod 32 rotates and drives the sealing plate 25 to rotate, the synchronizing rod 52 rotates synchronously, causing the block 51 to drive the rotating rod 41 to rotate, thereby allowing the pusher seat 43 to rotate and work normally.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
