Description

TECHNICAL FIELD

[0002] Rice bran oil is a plant oil extracted from rice bran, a byproduct of rice processing, and has rich nutritional value and multiple effects. Due to the characteristics of the raw material, the processing process and the storage requirements of rice bran oil, it needs to be refined. In the refining process of rice bran oil, a degumming and deodorizing drying device is usually used for treatment.

[0003] The existing rice bran oil degumming and deodorizing drying device usually sets corresponding degumming tanks, deodorizing tanks and drying tanks when refining rice bran oil. When degumming, deodorizing and drying rice bran oil, heating treatment is required. The heating body can only heat the corresponding tank body. After completing one process, the remaining heat cannot be utilized, and the tank body required for the next process needs to be heated again, increasing the cost and prolonging the refining time.

The first stirring component rapidly and efficiently stirs the rice bran oil located above the partition plate by rotating itself, reciprocating and lifting, and driving the material turning component to rotate synchronously, thereby accelerating the degumming rate of the rice bran oil. The deodorizing component introduces high-temperature steam into the rice bran oil through the combination of the rotating rod and the first stirring component, achieving full and efficient contact between the high-temperature steam and the rice bran oil, and realizing rapid and efficient deodorization treatment of the rice bran oil.

[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0059] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0060] In one embodiment of the present invention, see Figures 1-3 A rice bran oil degumming, deodorizing, and drying device includes an outer cylinder 1, an inner cylinder 109 inside the outer cylinder 1, an annular cavity 112 between the outer cylinder 1 and the inner cylinder 109, a top cover 102 on the top of the inner cylinder 109, a feed pipe 103 and a feeding pipe 104 respectively at both ends of the top cover 102 communicating with the inside of the inner cylinder 109, a partition 110 inside the inner cylinder 109, a central hole in the middle of the partition 110, a discharge pipe 111 at the bottom of the outer cylinder 1, a first solenoid valve (not shown in the figure) at the discharge pipe 111, a rotating rod 2 movably mounted inside the inner cylinder 109 and rotatingly cooperating with the top cover 102, a rotating assembly 3 connected to the rotating rod 2 mounted on the top cover 102, and the outer wall of the outer cylinder 1... A deodorization assembly 4 that cooperates with the rotating rod 2 is installed on the upper part. A first stirring assembly 5 that cooperates with the rotating rod 2 is provided inside the inner cylinder 109. The first stirring assembly 5 is located above the partition plate 110. A filter assembly 6 that cooperates with the central hole is movably provided on the partition plate 110. A material turning assembly 7 that cooperates with the rotating rod 2 is movably provided on the filter assembly 6. A second stirring assembly 8 that is connected to the rotating rod 2 is movably provided inside the inner cylinder 109. The second stirring assembly 8 is located below the partition plate 110. Several heating plates 9 are circumferentially distributed in the upper and lower parts of the annular cavity 112. The heating plates 9 located in the upper part of the annular cavity 112 correspond to the first stirring assembly 5, and the heating plates 9 located in the lower part of the annular cavity 112 correspond to the second stirring assembly 8.

[0061] In this embodiment, rice bran oil is introduced into the inner space of the outer cylinder 1 above the partition 110 through the feed pipe 103. The second stirring component 8 and the first stirring component 5% phosphoric acid are introduced into the inner space of the outer cylinder 1 above the partition 110 through the feeding pipe 104. The heating plate 9 corresponding to the first stirring component 5 is energized and generates heat, raising the temperature of the space above the inner cylinder 109 to 60-80℃, thus heating the rice bran oil located above the inner cylinder 109. This facilitates the heating of the rice bran oil located above the partition 110. The rotating component 3 drives the first stirring component 8 by rotating the rotating rod 2. A stirring component 5 rotates synchronously. The first stirring component 5 rapidly and efficiently agitates the rice bran oil located above the partition 110 by rotating itself, reciprocating, and lifting, as well as driving the material-turning component 7 to rotate synchronously, thus accelerating the degumming rate of the rice bran oil. When deodorization treatment of the rice bran oil is required, the heating plate 9 corresponding to the first stirring component 5 continues to heat, raising the temperature of the space above the inner cylinder 109 to 210-250℃. The deodorization component 4 introduces high-temperature steam into the rice bran oil through the rotating rod 2 in conjunction with the first stirring component 5, achieving full and efficient contact between the high-temperature steam and the rice bran oil, thus achieving deodorization of the rice bran oil. The rapid and efficient deodorization process is achieved; next, the filter assembly 6 is lifted upwards, releasing the contact between the filter assembly 6 and the partition 110. The degummed and deodorized rice bran oil will enter the inner cylinder 109 located below the partition 110 through the central hole of the filter assembly 6 and the partition 110. The heating plate 9 corresponding to the second stirring assembly 8 is energized and generates heat, causing the temperature of the space in the lower part of the inner cylinder 109 to rise to 100-120℃, which can heat the rice bran oil in the lower part of the inner cylinder 109. The rotating assembly 3 drives the second stirring assembly 8 to stir synchronously through the connection with the rotating rod 2. The stirring component 8 agitates and turns the rice bran oil located below the partition 110 by rotation, which can perform uniform and efficient drying of the rice bran oil, avoid local temperature differences during the drying process, and improve the uniformity of drying. After the rice bran oil has undergone degumming, deodorizing and drying treatment, the first solenoid valve is opened, and the discharge pipe 111 is in a conductive state, so that the degummed, deodorized and dried rice bran oil can be discharged. This can achieve efficient processing of rice bran oil and has the advantages of waste heat utilization, rapid and uniform agitation, efficient processing, anti-clogging, integrated cavity, convenient operation, reliable quality and energy saving and environmental protection.

[0062] The outer cylinder 1 has a support ring seat 101 at its bottom for stable support. The front of the outer cylinder 1 has a controller 105 electrically connected to the user equipment inside the device, which controls the start and stop of the equipment. The upper part of the inner cylinder 109 has a first vent pipe 106 penetrating the outer cylinder 1, the outer end of which is connected to the deodorization component 4, enabling waste heat recovery inside the inner cylinder 109 and improving heat utilization. The lower part of the inner cylinder 109 has a second vent pipe 107 penetrating the outer cylinder 1. To facilitate the exhaust of steam from the lower part of the inner cylinder 109 and the rapid drying of rice bran oil, a slag discharge pipe 108 is provided in the middle of the inner cylinder 109 above the partition 110. A second solenoid valve (not shown in the figure) is provided at the slag discharge pipe 108. Impurities can be filtered through the material turning assembly 7. During the degumming and deodorizing process of rice bran oil, the slag discharge pipe 108 is in a closed state. When the rice bran oil is dried, the second solenoid valve is opened, and the slag discharge pipe 108 is in a conductive state, which can exhaust impurities and maintain the cleanliness of the inside of the inner cylinder 109, which is conducive to the continuous degumming and deodorizing process of rice bran oil in the future.

[0063] In addition, by setting several heating plates 9 in an annular cavity (112), the residual heat from the previous process can be utilized for different processing stages of rice bran oil, avoiding the need to reheat the corresponding parts from scratch, improving the heat utilization rate, effectively reducing costs, and saving energy and protecting the environment.

[0064] In one embodiment of the present invention, see Figures 1-3 The rotating assembly 3 includes a rotating motor 301 mounted on the top of the upper cover 102. A rotating bevel gear 302 is mounted on the output shaft of the rotating motor 301. A rotating bevel gear ring 303 that meshes with the rotating bevel gear 302 is rotatably provided on the top of the upper cover 102.

[0065] In this embodiment, the rotary motor 301 drives the rotary bevel gear 302 to rotate. The rotary bevel gear 302 drives the rotating rod 2 to rotate synchronously by meshing with the rotary bevel gear ring 303. This can drive the first stirring component 5, the turning component 7, and the second stirring component 8 to rotate synchronously, thereby achieving efficient and uniform stirring of rice bran oil and improving the degumming, deodorizing, and drying efficiency of rice bran oil.

[0066] In one embodiment of the present invention, see Figures 1-6 and Figure 8The first agitation assembly 5 includes a fixing ring 501 disposed at the bottom of the upper cover 102. A first internal toothed ring 502 is installed on the inner wall of the fixing ring 501. A turntable 504 connected to the rotating rod 2 is rotatably disposed inside the fixing ring 501. A plurality of rotating holes (not marked in the figure) are distributed circumferentially on the turntable 504. A turntable 505 is rotatably disposed inside the rotating holes. An external toothed ring 503 that meshes with the first internal toothed ring 502 is disposed at the top of the turntable 505. A plurality of movable tubes 506 are vertically slidably disposed at the bottom of the turntable 505. A plurality of first agitation plates 507 are distributed along the axial direction on the outer wall of the movable tubes 506. A sliding column 508 is disposed at the top of the movable tubes 506. A connecting cylinder 509 connected to the rotating rod 2 is disposed on the side of the turntable 505 away from the upper cover 102. A first guide ring groove 510 that slides with the sliding column 508 is disposed on the inner wall of the connecting cylinder 509.

[0067] In this embodiment, the rotating component 3 drives the rotating rod 2 to rotate, thereby driving the turntable 504 and the connecting cylinder 509 to rotate synchronously. The turntable 504 drives several turntables 505 to rotate synchronously. The turntables 505 rotate in the rotating hole by meshing with the external toothed ring 503 and the first internal toothed ring 502, so that the turntables 505 revolve around the rotating rod 2 and rotate around the central axis of the turntables 505 at the same time. The turntables 505 drive several movable tubes 506 to revolve around the rotating rod 2 and around the central axis of the turntables 505 by slidingly engaging with several movable tubes 506. This can make the rotation trajectory of several movable tubes 506 interlaced petal-shaped, which can fully and efficiently agitate the rice bran oil and phosphoric acid located above the partition plate 110, and improve the degumming efficiency of the rice bran oil.

[0068] Meanwhile, as several movable tubes 506 revolve around the central axis of the turntable 505, the connecting cylinder 509 and the turntable 504 are relatively fixed, while the turntable 505 is in a state of rotation relative to the turntable 504. That is, the turntable 505 and the connecting cylinder 509 rotate relative to each other, and the turntable 505 drives several movable tubes 506 to rotate synchronously. The movable tubes 506 achieve their reciprocating lifting and lowering through the sliding cooperation of the sliding column 508 and the first guide ring groove 510, as well as the sliding cooperation between the movable tubes 506 and the turntable 505. This can achieve uniform stirring between rice bran oil and phosphoric acid and accelerate the degumming efficiency of rice bran oil.

[0069] The turntable 505 is provided with at least four units, and the movable tube 506 is provided with at least two units. The first guide ring groove 510 includes a first arc groove, a second arc groove, an ascending groove, and a descending groove. The first arc groove and the second arc groove have different heights, which can realize the reciprocating lifting and lowering of several movable tubes 506.

[0070] In one embodiment of the present invention, see Figures 1-3 and Figure 6The deodorization assembly 4 includes a steam box 401 installed on the outer wall of the outer cylinder 1 and a through hole 404 opened at the top of the rotating rod 2. A sealing cover 402 is installed on the steam box 401. A first steam guide pipe 403 communicating with the inside of the steam box 401 is provided on the sealing cover 402. The other end of the first steam guide pipe 403 is rotatably connected to the top of the rotating rod 2. The first steam guide pipe 403 is connected to the through hole 404. Several second steam guide pipes 405 communicating with the through hole 404 are distributed circumferentially on the outside of the rotating rod 2. The outer end of the second steam guide pipe 405 is rotatably engaged with the top of the turntable 505. A steam storage chamber 406 communicating with the second steam guide pipes 405 is opened in the turntable 505. A steam outlet pipe 407 is provided at the bottom of the movable pipe 506. Several steam outlets 408 are opened at the bottom of the steam outlet pipe 407.

[0071] In this embodiment, the high-temperature steam in the steam box 401 is introduced into the through hole 404 through the first steam guide pipe 403, and then into several steam storage chambers 406 through the second steam guide pipe 405. The high-temperature steam in the steam storage chambers 406 is introduced into the steam outlet pipe 407 through several movable pipes 506, and discharged into the internal space of the inner cylinder 109 through several steam outlets 408, so that the high-temperature steam can fully contact the rice bran oil.

[0072] The cooperation between the deodorizing component 4 and the first stirring component 5 facilitates thorough and uniform stirring of the degummed rice bran oil, allowing the high-temperature steam to come into full and uniform contact with the rice bran oil, thereby improving the deodorization efficiency of the rice bran oil.

[0073] In one embodiment of the present invention, see Figures 1-4 and Figure 6 The filter assembly 6 includes a filter screen 601 movably disposed above the partition 110. The bottom center of the filter screen 601 is movably engaged with the center hole of the partition 110. A connecting ring 603 located below the partition 110 is movably disposed inside the inner cylinder 109. A plurality of lifting columns 602 penetrating the partition 110 are connected between the filter screen 601 and the connecting ring 603. An electric cylinder 604 connected to the connecting ring 603 is installed on the inner wall of the inner cylinder 109.

[0074] In this embodiment, during the degumming and deodorizing process of rice bran oil, the bottom of the filter screen 601 and the top of the partition 110 are matched, and the center of the bottom of the filter screen 601 is matched with the center hole of the partition 110, which can stably support the rice bran oil and prevent the rice bran oil that has not been degummed and deodorized from entering the bottom of the partition 110.

[0075] After the rice bran oil has completed the degumming and deodorization process, the electric cylinder 604 extends upward and pushes the connecting ring 603 upward. The connecting ring 603 pushes the filter screen 601 upward in sync through the connection with the lifting column 602, releasing the fit between the bottom center of the filter screen 601 and the center hole of the partition 110. The rice bran oil will then pass through the filter screen 601 and the center hole of the partition 110 in sequence and flow to the lower inner side of the inner cylinder 109 for subsequent drying.

[0076] In one embodiment of the present invention, see Figures 1-4 and Figures 6-8 The material turning assembly 7 includes a side sliding groove 701 opened on the side wall of the rotating rod 2. A lifting ring cylinder 702 that slides and engages with the side sliding groove 701 is movably sleeved on the outer side of the rotating rod 2. The lifting ring cylinder 702 is rotatably engaged with the filter screen 601. Several second stirring plates 703 that are in active contact with the filter screen 601 are distributed circumferentially on the outer wall of the lifting ring cylinder 702. The second stirring plates 703 and the filter screen 601 are set at an acute angle.

[0077] In this embodiment, the rotating component 3 drives the rotating rod 2 to rotate. The rotating rod 2 drives several second stirring plates 703 to rotate synchronously through the sliding engagement of the side sliding groove 701 and the lifting ring cylinder 702, and the connection between the lifting ring cylinder 702 and the second stirring plate 703. The second stirring plates 703 can agitate the rice bran oil located above the filter screen 601, and at the same time, can prevent impurities from accumulating on the filter screen 601 and affecting the filtration effect of the rice bran oil.

[0078] In one embodiment of the present invention, see Figures 1-4 and Figures 9-11The second agitation assembly 8 includes a second internal gear ring 801 disposed on the inner wall of the inner cylinder 109. The second internal gear ring 801 is located below the partition plate 110. The rotating rod 2 has several supports 804 distributed circumferentially. The outer ends of the supports 804 are connected to a vertical cylinder 803. A scraper 8031 ​​is provided on the side of the vertical cylinder 803 near the inner wall of the inner cylinder 109. A return port 8032 is opened at the upper part of the vertical cylinder 803. A slot 8033 is opened at the bottom of the side wall of the vertical cylinder 803. An auger 809 is rotatably disposed inside the vertical cylinder 803. The top of the auger 809 penetrates the vertical cylinder 803 and is connected to a transmission that meshes with the second internal gear ring 801. The gear 802, the auger 809 is provided with a second guide ring groove 8091 located between the vertical cylinder 803 and the transmission gear 802, the bracket 804 is movably provided with a movable rod 805, and a number of third stirring plates 806 are axially distributed at the end of the movable rod 805 away from the bracket 804. A number of connecting plates 807 are distributed circumferentially inside the inner cylinder 109. One end of the connecting plate 807 is rotatably engaged with the top of the movable rod 805, and the other end of the connecting plate 807 is sleeved on the outside of the auger 809 and slidably engaged with the second guide ring groove 8091. The connecting plate 807 is connected to a guide rod 808 that is slidably engaged with the bracket 804.

[0079] In this embodiment, the rotating assembly 3 drives the rotating rod 2 to rotate. The rotating rod 2 drives several movable rods 805 and the vertical cylinder 803 to rotate synchronously through connection with the bracket 804. The vertical cylinder 803 drives the auger 809 to rotate synchronously. The auger 809 is driven to rotate through the meshing of the transmission gear 802 and the second internal gear ring 801. During the rotation of the vertical cylinder 803, the rice bran oil located at the bottom of the inner cylinder 109 enters the interior of the vertical cylinder 803 through the slot 8033. The auger 809 rotates through the meshing of the transmission gear 802 and the second internal gear ring 801. The rice bran oil at the bottom of the vertical cylinder 803 is lifted by the inner wall of the vertical cylinder 803. The lifted rice bran oil will flow back into the inner cylinder 109 through the return port 8032, realizing the flow between the bottom and top of the rice bran oil, which facilitates the comprehensive and uniform drying of the rice bran oil and avoids the problem of local overheating of the rice bran oil. The vertical cylinder 803 is connected to the scraper 8031 ​​to scrape off the rice bran oil adhering to the inner wall of the inner cylinder 109, thereby improving the drying efficiency of the rice bran oil and keeping the inside of the inner cylinder 109 clean.

[0080] Meanwhile, the support 804 drives the movable rod 805 to revolve around the rotating rod 2 through a movable cooperation with the movable rod 805. During the revolution of the movable rod 805, due to the resistance of the rice bran oil, the movable rod 805 will drive the third stirring plate 806 to rotate around the movable rod 805. This causes several third stirring plates 806 to revolve around the rotating rod 2 and the movable rod 805 at the same time, thereby improving the stirring effect of the rice bran oil and facilitating the rapid and uniform drying of the rice bran oil.

[0081] Furthermore, the connecting plate 807 drives the movable rod 805 to reciprocate up and down by slidingly engaging with the second guide ring groove 8091, slidingly engaging with the guide rod 808 and the bracket 804, and rotating with the connecting plate 807 and the movable rod 805. This improves the stirring effect of the rice bran oil below the partition 110 and avoids the problem of oil polymerization and black sedimentation that can block the pipes caused by local overheating of the rice bran oil.

[0082] In one embodiment of the present invention, a method for degumming, deodorizing, and drying rice bran oil includes the following steps:

[0083] Step S1: Rice bran oil is introduced into the inner space of the outer cylinder 1 above the partition 110 through the feed pipe 103, and 85% phosphoric acid is introduced into the inner space of the outer cylinder 1 above the partition 110 through the feed pipe 104.

[0084] Step S2: The heating plate 9 corresponding to the first stirring component 5 is energized and generates heat, causing the temperature of the space above the inner cylinder 109 to rise to 60-80℃;

[0085] Step S3: The rotating component 3 drives the first stirring component 5 to rotate synchronously by driving the rotating rod 2 to rotate. The first stirring component 5 quickly and efficiently stirs the rice bran oil located above the partition plate 110 by rotating itself, reciprocating and lifting, and driving the material turning component 7 to rotate synchronously, thereby accelerating the degumming rate of the rice bran oil.

[0086] Step S4: The heating plate 9 corresponding to the first stirring component 5 continues to heat, so that the temperature of the space above the inner cylinder 109 rises to 210-250℃;

[0087] Step S5: The deodorization component 4 introduces high-temperature steam into the rice bran oil through the combination of the rotating rod 2 and the first stirring component 5, so as to achieve full and efficient contact between the high-temperature steam and the rice bran oil, and achieve rapid and efficient deodorization treatment of the rice bran oil.

[0088] Step S6: The filter assembly 6 is lifted upward to release the contact between the filter assembly 6 and the partition 110. The rice bran oil after degumming and deodorization will enter the inner space of the inner cylinder 109 located below the partition 110 through the central hole of the filter assembly 6 and the partition 110.

[0089] Step S7: The heating plate 9 corresponding to the second stirring component 8 is energized and generates heat, so that the temperature of the space in the lower part of the inner cylinder 109 rises to 100-120℃. The rotating component 3 drives the second stirring component 8 to stir synchronously through the connection with the rotating rod 2. The second stirring component 8 stirs and turns the rice bran oil located below the partition plate 110 by rotating, which can perform uniform and efficient drying of the rice bran oil.

[0090] Step S8: After the rice bran oil has undergone degumming, deodorizing and drying treatment, open the first solenoid valve, and the discharge pipe 111 is in the conducting state to discharge the degummed, deodorized and dried rice bran oil.
