The physiologically active ingredients with high nutritional value in cereal crops are concentrated in the aleurone layer, of which 20% of pure aleurone layer is equivalent to the effect of the whole grain. During the milling process, the aleurone layer of wheat and rice is usually attached to the husk and peeled off to become bran, but the unseparated aleurone layer has a low absorption rate in the human body, so separation equipment is often used to separate the aleurone layer from the bran.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0032] The bran aleurone layer separation device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1-Figure 9 As shown, the bran endosperm separation device according to the embodiment of the present invention includes a housing 1, two groups of rollers 2, a plurality of separation mechanisms 3, a driving mechanism 4, a screening unit 5 and a feeder 6.

[0034] The two rollers 2 are respectively arranged in the shell 1 . An inclined filter plate 11 is arranged in the shell 1 . The filter plate 11 is located below the rollers 2 .

[0035] It should be noted that the two rollers 2 rotate in opposite directions to form a grinding and scraping area in between. Since the moist bran has a certain toughness, the rollers 2 will not crush the bran, thus ensuring the integrity of the bran when separating the endosperm layer, and preventing the bran from being crushed and mixed with the endosperm layer, thereby reducing the difficulty of separation.

[0036] The inclined filter plate 11 can perform primary filtration of the endosperm, and the inclined structure can guide the unfiltered endosperm and bran into subsequent structural components for secondary separation, thereby improving the endosperm separation effect.

[0037] Among them, a plurality of separation mechanisms 3 are evenly arranged on the corresponding roller shafts 2 , and the separation mechanisms 3 include a hemispherical seat 31 , a ball 32 , a rubber pad 33 , a plurality of separation grooves 34 and a ball auxiliary structure 35 .

[0038] Among them, the hemispherical seat 31 is set on the roller shaft 2, and a receiving groove is opened on the hemispherical seat 31. The ball 32 is clamped and set in the receiving groove. The rubber pad 33 is set in the receiving groove and is closely connected with the ball 32. A plurality of separation grooves 34 are evenly opened on the ball 32, and the ball auxiliary structure 35 is set on the roller shaft 2.

[0039] It should be noted that a hemispherical spherical groove structure is arranged inside the hemispherical seat 31, and the ball 32 can be engaged in the spherical groove structure. Through this structure, the ball 32 is separated from the hemispherical seat 31. The ball 32 cooperates with the hemispherical seat 31 to form a protrusion on the roller 2, thereby improving the grinding performance of the bran falling between the rollers 2 and increasing the separation rate of the starch layer.

[0040] The ball 32 is provided with a plurality of separation grooves 34, which change the surface structure of the ball 32 to form an angular structural edge. While the ball 32 grinds the bran, the angular edges of the separation grooves 34 further enhance the scraping effect on the endosperm layer, ensuring that the endosperm layer adhering to the bran surface is scraped off.

[0041] The rubber pad 33 can squeeze the ball 32. The squeezing of the rubber pad 33 can improve the damping of the ball 32 rotation, thereby improving the scraping force on the starch layer on the bran surface. Correspondingly, the ball auxiliary structure 35 can change the expansion degree of the rubber pad 33 by heating, thereby appropriately adjusting the damping of the ball 32. In addition, due to the separation groove 34 structure on the surface of the ball 32, part of the separated starch layer may stick to the inside. The ball auxiliary structure 35 can provide air pressure assistance to blow away the stuck starch layer to prevent the starch layer from sticking to the ball 32 and the hemispherical seat 31.

[0042] Wherein, the driving mechanism 4 is arranged on the roller shaft 2;

[0043] It should be noted that the driving mechanism 4 is connected to the roller shaft 2 to drive the rotation of the roller shaft 2 to ensure that the roller shaft 2 keeps a stable rotation state during the separation process.

[0044] The screening unit 5 is arranged on the housing 1 .

[0045] It should be noted that the screening unit 5 can perform secondary filtration on the bran and endosperm mixture that has completed preliminary filtration on the filter plate 11, and finally separate the endosperm from the bran, thereby improving the separation rate of the bran.

[0046] The feeder 6 is arranged on the top surface of the shell 1 .

[0047] It should be noted that the feeder 6 is used to guide the bran material into the shell 1 for starch layer separation. At the same time, the feeder 6 can be positioned between the two rollers 2 to ensure that the bran can enter the area between the rollers 2 for separation, thereby improving the stability of the equipment operation and reducing deviations.

[0048] A starch layer discharge port 12 is provided on the bottom surface of the shell 1 .

[0049] It should be noted that the bottom surface of the shell 1 is provided with an aleurone layer discharge port 12 , which is located directly below the filter plate 11 and can discharge the aleurone layer filtered out by primary filtration to the outside of the device for collection.

[0050] Specifically, the relevant staff will feed the prepared bran through the feeder 6 and operate the driving mechanism 4 to control the rotation of the roller 2 at the same time. The bran enters between the rollers 2 and is squeezed and guided by the rollers 2. The hemispherical seat 31 and the ball 32 on the surface of the roller 2 enhance the grinding and squeezing of the bran. The separation groove 34 on the surface of the ball 32 scrapes off the starch layer stuck on the surface of the bran. If the adhesion is high, the ball auxiliary structure 35 can be operated to heat up, increase the expansion degree of the rubber pad 33, increase the damping property of the ball 32, and enhance the scraping force. A small amount of starch layer stuck on the ball 32 can be blown out by the air pressure provided by the ball auxiliary structure 35.

[0051] After being ground and scraped off, the endosperm layer falls onto the filter plate 11 together with the bran for preliminary filtration. Since the bran is not broken and cannot pass through the filter plate 11, the endosperm layer is filtered through the filter plate 11 and finally discharged from the endosperm layer discharge port 12.

[0052] A small amount of endosperm layer and bran enter into the screening unit 5 together, and the screening unit 5 performs a second screening on the endosperm layer and bran. After the screening is completed, the bran is discharged and the endosperm layer is recovered, thus completing the entire separation process of the bran endosperm layer.

[0053] In one embodiment of the present invention, Figure 6 As shown, the ball auxiliary structure 35 includes a guide tube 351 , an air cavity 352 and two heating plates 353 .

[0054] The conduit 351 is rotatably disposed on the first side of the roller shaft 2 , the air cavity 352 is opened on the roller shaft 2 , the air cavity 352 is communicated with the corresponding separation groove 34 , and the two heating plates 353 are respectively disposed in the air cavity 352 .

[0055] It should be noted that the conduit 351 can be connected to an external air supply component to supply air to the inside of the air cavity 352. At the same time, the air cavity 352 is connected to the interior of each hemispherical seat 31. The conduit 351 is rotatably connected to the roller shaft 2, which can ensure that the conduit 351 maintains the normal rotation of the roller shaft 2 when normal air supply is provided.

[0056] It can be understood that the duct 351 cooperates with the air cavity 352 to supply air to the inside of the hemispherical seat 31, and can blow away the paste layer adhering to the separation groove 34 through high air pressure. The heating plate 353 can change the temperature of the roller 2, thereby affecting the temperature of the rubber pad 33 that is in contact with it, changing the expansion rate of the rubber pad 33, and adjusting the damping properties of the ball 32.

[0057] Specifically, when relevant staff find that there may be adhesion in the separation groove 34 during the separation process of the starch layer, they can supply air through an external air supply component, and high-pressure gas is sent into the hemispherical seat 31 through the conduit 351 and the air cavity 352 to clean the starch layer on the surface of the separation groove 34. When it is necessary to improve the scraping effect, the heating plate 353 is operated to change the temperature of the rubber pad 33 and the scraping ability of the ball 32.

[0058] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the driving mechanism 4 includes two gears 41 , a first driver 42 and a fixed housing 43 .

[0059] Among them, two gears 41 are rotatably set on the shell 1 respectively, the two gears 41 are respectively connected to the corresponding roller shafts 2, the two gears 41 are meshed and connected, the first driver 42 is set on one side of the gear 41, the fixed shell 43 is set on the shell 1, the gear 41 and the first driver 42 are located in the fixed shell 43, and the fixed shell 43 is connected to the first driver 42.

[0060] It should be noted that the driving mechanism 4 mainly drives the roller shaft 2 and allows the two roller shafts 2 to rotate in opposite directions at the same time. Gears 41 are connected to the two roller shafts 2, and the gears 41 are meshed with each other. The meshed gears 41 rotate in opposite directions. When one of the gears 41 rotates, the other gear 41 is driven, thereby realizing the simultaneous rotation control of the roller shafts 2 in opposite directions.

[0061] The first driver 42 is a servo motor, and the rotation of the gear 41 can be controlled by directly remotely controlling the servo motor from the outside.

[0062] Specifically, when the bran starch layer is separated, the relevant staff operates the first driver 42, and the first driver 42 drives one of the gears 41 to rotate, and drives the other gear 41 to rotate in the opposite direction, so as to ensure the normal operation of the roller 2 and process the bran.

[0063] In one embodiment of the present invention, Figure 2 and Figure 7 As shown, the screening unit 5 includes a separation drum 51 , a filter gear 52 , a rotating structure 53 , a dust collector 54 and an auxiliary screening structure 55 .

[0064] Among them, the separation cylinder 51 is arranged on the shell 1 and is connected to its interior, the filter gear 52 is rotatably arranged in the separation cylinder 51, the rotating structure 53 is arranged on the separation cylinder 51 and is connected to the filter gear 52, the vacuum cleaner 54 is arranged on the separation cylinder 51, and the auxiliary screening structure 55 is arranged on the filter gear 52.

[0065] It should be noted that the vacuum cleaner 54 can be composed of a negative pressure unit and a collection component, and the negative pressure unit provides negative pressure suction to suck the bran and the endosperm into the separation cylinder 51, and perform secondary screening with the help of the filter gear 52. After the endosperm is completely sucked in, it is collected by the collection component to facilitate subsequent removal and processing. In addition, holes can be opened on the housing 1 to provide air circulation for the vacuum cleaner 54 to suck.

[0066] The filter gear 52 may be composed of a filter and a rotating gear. The rotating gear is hollow inside and a filter is installed therein. The filter can filter. The external rotating gear may be driven to rotate the filter, thereby achieving a driving control effect.

[0067] The auxiliary screening structure 55 can improve the screening efficiency of the filter gear 52. Due to the suction force of the vacuum cleaner 54, the bran may be adsorbed and fixed on the filter gear 52, and the auxiliary screening structure 55 can clean the adsorbed bran.

[0068] It can be understood that the vacuum cleaner 54 provides suction to suck the bran into the separation cylinder 51, and the filter gear 52 cooperates with the auxiliary screening structure 55 for secondary screening. The filter gear 52 can be driven to rotate by the rotating structure 53, and cooperates with the auxiliary screening structure 55 to remove the bran.

[0069] In order to clearly explain the above embodiment, in one embodiment of the present application, Figure 2 and Figure 4 As shown, the rotating structure 53 includes a driving gear 531 , a second driver 532 , a rotating ring plate 533 and a rotating ring groove 534 .

[0070] Among them, the driving gear 531 is arranged at the bottom of the filter gear 52 and is meshed with it, the second driver 532 is arranged on the bottom surface of the separation cylinder 51, the second driver 532 is connected to the driving gear 531, the swivel plate 533 is arranged on the separation cylinder 51, the swivel groove 534 is opened on the filter gear 52, and the swivel plate 533 is located in the swivel groove 534.

[0071] It should be noted that the second driver 532 can be an electric motor, which is connected to the driving gear 531 to drive the driving gear 531 to rotate.

[0072] It can be understood that the second driver 532 controls the driving gear 531 to rotate, thereby driving the filter gear 52 meshing therewith to rotate, and the swivel plate 533 is engaged in the swivel groove 534, which supports the filter gear 52 while ensuring its rotatability.

[0073] In order to clearly explain the above embodiment, in one embodiment of the present application, Figure 3 and Fig. 9 As shown, the auxiliary screening structure 55 includes a stopper 551 , a lower filter plate 552 , a vertical baffle 553 and a valve pipe 554 .

[0074] Among them, the stopper 551 is set on one side of the filter gear 52, and the stopper 551 is located between the filter gear 52 and the vacuum cleaner 54. The lower filter plate 552 is obliquely set on the other side of the filter gear 52 and is located below the stopper 551. The vertical baffle 553 is set on the lower filter plate 552. The valve pipe 554 is set on one side of the separation cylinder 51, and the valve pipe 554 is located above the lower filter plate 552.

[0075] It should be noted that the block 551 can block the suction generated by the vacuum cleaner 54, forming an area without suction in the entire separation cylinder 51. Since the filter gear 52 is rotating, the bran adsorbed on it loses suction when it rotates to the area of ​​the block 551, and the bran falls onto the lower filter plate 552. The lower filter plate 552 filters the last small amount of starch layer remaining on the bran. After filtering, the starch layer is sucked in and collected by the vacuum cleaner 54, and the bran is discharged to the outside of the equipment through the opened valve pipe 554. The vertical baffle 553 can block the side suction to a certain extent, ensuring that the suction is reduced after entering the block 551 area, and the bran pile with a certain weight can no longer be adsorbed.

[0076] Specifically, when the relevant staff performs secondary separation treatment on the bran and the endosperm, they operate the vacuum cleaner 54 to provide suction, suck the bran and the endosperm remaining from the primary filtration into the separation cylinder 51, operate the second driver 532, and drive the filter gear 52 to rotate through the driving gear 531. The filter gear 52 rotates stably with the assistance of the swivel plate 533 and the swivel groove 534, and the endosperm passes through the filter gear 52 and is collected by the vacuum cleaner 54. The remaining endosperm and bran are brought to the block 551 through the rotation of the filter gear 52. After losing the adsorption force, the bran and the remaining endosperm fall off, and the endosperm is filtered again and enters under the bottom filter plate 552 to be adsorbed and collected by the vacuum cleaner 54. Finally, the separated bran is discharged by opening the valve pipe 554.

[0077] In one embodiment of the present invention, Figure 1 and Figure 8 As shown, the feeder 6 includes a feed hopper 61 , a guide roller 62 and a third driver 63 .

[0078] The feed hopper 61 is arranged on the top surface of the shell 1 , and the feed hopper 61 is located between the two roller shafts 2 . The guide roller 62 is rotatably arranged on one side of the feed hopper 61 . The third driver 63 is arranged on the feed hopper 61 and connected to the guide roller 62 .

[0079] It should be noted that the top of the feed hopper 61 is a bucket-shaped structure, and the bottom is a strip-shaped square tube structure, inside which a guide roller 62 is arranged. The guide roller 62 is inside the strip-shaped square tube structure of the feed hopper 61 and is located on one side, so that the bran can be guided to one side for separate discharge, and at the same time, the size of the discharge gap is controlled so that the bran will not accumulate in large quantities when it enters between the roller shafts 2, but only a thin layer, ensuring that the ball 32 can stably and reliably contact the starch layer on the surface of the bran, and effectively grind and scrape it.

[0080] The third driver 63 may be a built-in motor, which is convenient for directly controlling the rotation of the guide roller 62 .

[0081] Specifically, the relevant staff operates the third driver 63, and the third driver 63 drives the guide roller 62 to rotate, and feeds the bran into the hopper 61 from the top. The guide roller 62 inside the hopper 61 rotates to drive the bran downward, and the bran enters between the rollers 2 for starch layer separation.

[0082] In summary, the endosperm layer can be rubbed and scraped off the bran without crushing the bran. There is no need to accurately control the crushing particle size, and the process is simpler, thereby improving the efficiency of endosperm layer separation.
