[0002] Low-GI recombinant red rice is a red rice product prepared by a specific process and having a low glycemic index. It uses red rice as the main raw material. Because it is rich in various nutrients and unique color, it helps to improve the nutritional value and appearance of the recombinant rice. Combined with other auxiliary materials and functional components, this red rice helps to control the postprandial blood glucose level and is suitable for diabetic patients or people who need to control blood glucose. At the same time, according to the formula requirements, other auxiliary materials can also be selected, such as low-GI value ingredients like chickpeas, black beans, oats, tartary buckwheat, konjac flour, etc. These ingredients not only help to reduce the GI value of the recombinant rice, but also provide rich dietary fiber and minerals.

The connecting plate 305 moves through the chute opened in the upper preparation box 1, and the sliding block 304 and the push block 306 both move through the chute opened in the upper preparation box 1.

[0068] It should be noted that the chute opened in the upper preparation box 1 enables the sliding block 304, the connecting plate 305, and the push block 306 to move and be limited better.

[0069] In the present invention, preferably, it further includes a cleaning component 4. There are two groups of cleaning components 4, which are respectively installed on both sides inside the upper preparation box 1, and the cleaning component 4 is used to clean the surfaces of the two groups of rolling rollers 11.

[0070] In the present invention, preferably, the cleaning component 4 includes a connecting frame 400, and the connecting frame 400 slides inside the upper preparation box 1;

[0071] A threaded rod 401, the threaded rod 401 is threadedly connected to one side of the upper preparation box 1, and a limit disk 402 is fixedly connected to one side of the threaded rod 401;

[0072] A cleaning blade 403, sliding plates 404 slide on both sides of the cleaning blade 403, and a limit block 405 is fixedly connected to one side of the sliding plate 404, and a second spring 406 is fixedly connected to the other side of the sliding plate 404;

[0073] Limit columns 407, there are two groups of limit columns 407, and they are both fixedly connected to the chutes opened on both sides of the cleaning blade 403.

[0074] It should be noted that connecting grooves are arranged on both sides inside the connecting frame 400 to facilitate connection with the two groups of limit blocks 405, so that the cleaning blade 403 and the connecting frame 400 are more convenient for connection and disassembly;

[0075] One side of the cleaning blade 403 is attached to the surface of the rolling roller 11, and the tip of the cleaning blade 403 is in contact with the surface of the rolling roller 11;

[0076] A knob is fixedly connected to the side of the threaded rod 401 away from the limit disk 402 to facilitate the rotation of the threaded rod 401, and half of the threaded rod 401 is exposed outside the upper preparation box 1.

[0077] In the present invention, preferably, both the sliding plate 404 and the limiting block 405 slide on the limiting column 407. The second spring 406 is sleeved on the limiting column 407.

[0079] The setting of the limiting column 407 can guide the movement of the sliding plate 404 and the limiting block 405.

[0080] During the implementation process, rotate the rocker 301. The rocker 301 drives the bidirectional lead screw 300 to rotate along the upper preparation box 1. The rotation of the bidirectional lead screw 300 causes both groups of connecting plates 305 to move inward or outward simultaneously along the sliding grooves opened on the upper preparation box 1 through the limiting of the upper preparation box 1. Both groups of connecting plates 305 drive both groups of sliding blocks 304, the first motor 10, and the rolling rollers 11 to move inward or outward to adjust the distance, making it easier to adjust the distance between the two rolling rollers 11 to facilitate adjusting the fineness when the brown rice and the auxiliary materials are extruded. When the two sliding blocks 304 move inward or outward, they squeeze or push the pushing blocks 306 on both sides, causing the pushing blocks 306 to automatically fill the gaps at the sliding grooves of the upper preparation box 1 through the pushing or contraction of the first spring 307 to prevent waste caused by the extrusion and ejection of various cereal materials and auxiliary materials.

[0081] Two first motors 10 are provided. The output ends of both first motors 10 drive both rolling rollers 11 to rotate along the sliding blocks 304. The rotation of the two rolling rollers 11 extrudes the various cereal materials and auxiliary materials entering from the feeding port of the upper preparation box 1.

[0082] Rotate the threaded rod 401. The threaded rod 401 rotates along one side of the upper preparation box 1 and then moves forward or backward along the threaded rod 401. The threaded rod 401 drives the limiting disc 402, the connecting frame 400, and the cleaning blade 403 to move forward or backward to adjust the contact distance with the rolling roller 11. At the same time, it pushes the two sliding plates 404. Both sliding plates 404 drive the limiting blocks 405 to move inward along the sliding grooves opened on the cleaning blade 403, thereby squeezing the second spring 406, and taking out the limiting blocks 405 from the connecting grooves of the connecting frame 400, making it easier to disassemble the cleaning blade 403.

[0096] Both the moving block 502 and the fixed frame 500 are provided with grooves for connecting with the limit pin 503, so that the screen 501 can be limited when it is inside the fixed frame 500.

[0097] The guide post 509 can guide the moving plate 504 when it moves.

[0098] During the implementation process, when the various crushed cereal materials and auxiliary materials fall onto the screen 501 in the lower preparation box 2 through the upper preparation box 1, the second motor 506 is set. The output end of the second motor 506 drives the transmission shaft 507 to rotate along the middle of the lower preparation box 2. The transmission shaft 507 drives the cam 508 to rotate. The rotation of the cam 508 makes the fixed frame 500 drive the screen 501 to move up and down along the guide post 509 and the chute through the two moving plates 504 and quickly push downward through the reaction force of the third spring 505, so that the fixed frame 500 drives the screen 501 to bounce up and down, thereby accelerating the screening effect of the various crushed cereal materials and auxiliary materials on the screen 501, and the remaining brown rice and auxiliary materials in the screen 501 can also fall by shaking up and down, thereby maintaining the filtering effect of the screen 501 and improving the screening efficiency after the brown rice and auxiliary materials are crushed.

Put brown rice into the soaking unit and add a 0.1% lactic acid solution (pH 5.5), and perform ultrasonic treatment at 40 °C for 2 hours.

[0110] It should be noted that the variety of cereal materials include brown rice, red rice, chickpeas, black beans, oats, tartary buckwheat, konjac powder, etc.

[0111] Perform segmented pressure cooking on the soaked variety of cereal materials;

[0112] A more specific implementation method is as follows: Place the soaked variety of cereal materials in a segmented pressure tank. The first stage is low-pressure pre-gelatinization (0.1 MPa, 80 °C, 10 min), and the second stage is high-pressure shaping (0.5 MPa, 110 °C, 5 min).

[0113] Cool the cooked variety of cereal materials;

[0114] A more specific implementation method is as follows: Place various cereal materials in an environment with a humidity of 85%, and slowly cool from 60°C to 30°C (40 minutes).

[0115] Add crushed auxiliary materials to the cooled various cereal materials for mixing;

[0116] A more specific implementation method is as follows: Add crushed auxiliary materials to the cooled various cereal materials and stir and mix them through an external stirrer (not shown).

[0117] It should be noted that the auxiliary materials are raw materials such as chickpeas, black beans, oats, tartary buckwheat, konjac powder, etc.

[0118] Pour the mixture of various cereal materials and auxiliary materials into the upper preparation box 1, adjust the distance between the two sets of rolling rollers through the adjustment component and roll them through the two sets of rolling rollers, and at the same time clean the surfaces of the two sets of rolling rollers through the cleaning component;

[0119] A more specific implementation method is as follows:

[0120] Rotate the rocker 301, the rocker 301 drives the bidirectional lead screw 300 to rotate along the upper preparation box 1, and the rotation of the bidirectional lead screw 300 causes both sets of connecting plates 305 to move inward or outward along the chute opened in the upper preparation box 1 through the limit of the upper preparation box 1 at the same time. Both sets of connecting plates 305 drive both sets of sliding blocks 304, the first motor 10, and the rolling roller 11 to move inward or outward to adjust the distance, making it easier to adjust the distance between the two sets of rolling rollers so as to adjust the fineness when the various cereal materials and auxiliary materials are extruded. When the two sets of sliding blocks 304 move inward or outward, they squeeze or push the pushing blocks 306 on both sides, so that the pushing blocks 306 automatically supplement the gaps at the chute of the upper preparation box 1 through the pushing or contraction of the first spring 307 to prevent the various cereal materials and auxiliary materials from being thrown out during extrusion, resulting in waste;

[0121] Set two first motors 10, the output ends of the two first motors 10 drive the two sets of rolling rollers 11 to rotate along the sliding blocks 304. The rotation of the two sets of rolling rollers 11 rolls the red rice and auxiliary materials entering from the feed port of the upper preparation box 1. When the two sets of rolling rollers 11 rotate and contact the cleaning blade 403, the residues remaining on the surface can be cleaned off.

[0122] Screen and select the rolled red rice and auxiliary materials through the filtering component;

[0123] A more specific implementation method is as follows:

[0124] When the extruded multi-grain materials and auxiliary materials particles fall onto the screen 501 in the lower preparation box 2 through the upper preparation box 1, the second motor 506 is set. The output end of the second motor 506 drives the transmission shaft 507 to rotate along the middle of the lower preparation box 2. The transmission shaft 507 drives the cam 508 to rotate. The rotation of the cam 508 causes the fixing frame 500 to drive the screen 501 to move up and down along the guide column 509 and the chute through two sets of moving plates 504 and be quickly pushed downward by the reaction force of the third spring 505, so that the fixing frame 500 drives the screen 501 to bounce up and down, thereby accelerating the screening effect of the multi-grain materials and auxiliary materials particles on the screen 501, and the remaining multi-grain materials and auxiliary materials particles in the screen 501 can also fall off through the up and down shaking.

[0125] The discharged components are used to discharge and push out the screened multi-grain materials and auxiliary materials and conduct drying.

[0126] A more specific implementation manner is as follows:

[0127] While the second motor 506 drives the transmission shaft 507 to rotate, it also drives the first sprocket 604 to rotate. The first sprocket 604 drives the chain 605 to rotate. The chain 605 drives the second sprocket 606 to rotate. The second sprocket 606 drives the reciprocating lead screw 601 to rotate along the middle of the positioning block 600. The rotation of the reciprocating lead screw 601 causes the connecting block 602 to move back and forth along the chute opened by the reciprocating lead screw 601 and the positioning block 600. The connecting block 602 drives the push plate 603 to move back and forth, thereby pushing the screened multi-grain materials and auxiliary materials particles in the lower preparation box 2 back and forth, so that the multi-grain materials and auxiliary materials particles are discharged through the discharge slots 8 opened on both sides of the lower preparation box 2 and slide down through the guide plate 9;

[0128] The screened grain materials and auxiliary materials particles are subjected to infrared drying;

[0129] A more specific implementation manner is as follows: far-infrared radiation drying (50 - 60 °C), controlling the moisture content to 12% - 14%, preventing starch retrogradation, and drying to a moisture content of 13% by infrared.

[0130] It should be noted that the low-GI red rice in the present invention is not limited to red rice and brown rice, and can also be grains such as millet, sorghum, and coix seed.

[0131] The above has described a specific embodiment of the present invention in detail, but the described content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
