Description

Technical Field

[0001] This invention relates to the field of wheat flour processing technology, specifically a process for preparing high-gluten wheat flour. Background Technology

[0002] In the current wheat flour processing and preparation process, when the wheat flour has insufficient gluten content, gluten powder is mixed with wheat flour to make the wheat flour meet the high gluten requirements;

[0003] In the current wheat flour processing and preparation process, wheat flour grinding equipment is usually used to grind wheat flour and bran and then sieve them, which is inefficient.

[0004] In the current wheat flour processing and preparation process, wheat flour and bran are ground and sieved together. In the subsequent grinding process, the bran containing wheat flour is wrapped around the ground wheat flour, resulting in poor wheat flour removal. The ground wheat flour needs to be ground a second time, which affects the production efficiency of the equipment.

[0005] In the current wheat flour processing and preparation process, long-term operation of the equipment can cause material to clog between the grinding discs. Over time, the wheat flour will form bridges or harden due to the high grinding temperature, requiring the grinding discs to be disassembled and cleaned separately, which is time-consuming and labor-intensive.

[0006] In the current wheat flour processing and preparation process, the wheat flour grinding effect is not good. If there is a lot of wheat flour residue on the bran, it needs to be ground again. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a high-gluten wheat flour preparation process that solves problems encountered during wheat flour processing.

[0015] The first grinding surface is disposed outside the first inner grinding surface and forms a wheat flour grinding gap with each other. The anti-clogging grinding surface and the sieving part form a space for sieving wheat flour. The second grinding surface is disposed outside the second inner grinding surface and forms a wheat flour grinding gap with each other. The third grinding surface is disposed outside the third inner grinding surface and forms a wheat flour grinding gap with each other. The first grinding surface and the first inner grinding surface, the second grinding surface and the second inner grinding surface are vertical.

[0016] The inner side of the internal grinding mechanism is provided with multiple sets of feeding components from top to bottom, and the feeding components include multiple collection hoppers provided inside each screening section;

[0017] The reset mechanism includes multiple stops and multiple limiting rods, with the multiple limiting rods and multiple stops fixed correspondingly. Multiple first limiting grooves are provided on the outer side of the outer grinding ring, and each stop slides in a corresponding first limiting groove. A limiting sleeve is fixed in each first limiting groove, and each limiting rod slides relative to its corresponding limiting sleeve. A first spring is fixed to one end of each limiting rod, and each first spring is disposed in its corresponding limiting sleeve. A wavy first sliding groove is provided around the bottom inner wall of the outer grinding ring, and a first sliding rod is rotatably connected to the bottom outer side of the inner grinding ring, with the first sliding rod slidingly disposed in the first sliding groove.

[0018] Preferably, the rocking mechanism includes a mounting base and a limiting base. There are multiple limiting bases and they are disposed on the inner wall of the frame. Multiple second limiting grooves are provided on the outer side of the mounting base. The limiting base slides in the corresponding second limiting groove. A second spring is provided in each of the second limiting grooves. The second spring elastically compresses the corresponding limiting base. A wave-shaped second sliding groove is provided around the inner side of the mounting base. A second sliding rod slides in the second sliding groove. The second sliding rod rotates on one side of the bottom of the inner grinding ring.

[0019] Preferably, the screening mechanism includes a flour bucket, a skirt, and a sieve bucket. The sieve bucket is detachably installed at the bottom of the mounting base. A screen is provided at the bottom of the sieve bucket. A skirt is installed on the outer periphery of the bottom of the sieve bucket. The flour bucket is located directly below the sieve bucket. The bottom of the lowest collecting hopper is connected to a discharge pipe. The lower part of the discharge pipe passes through the sieve bucket and extends outward.

[0020] Preferably, the driving mechanism includes a drive box and a motor. The drive box is mounted on the frame, and the motor is mounted inside the drive box. A first pulley is fixed to the driving end of the motor. The top of the inner grinding ring is mounted on the lower part of the feed hopper of the frame via a bracket. A second pulley is fixed to the top of the inner grinding ring. The first pulley is connected to the second pulley via a belt. Both the first pulley and the second pulley are mounted inside the drive box, and one end of the drive box extends to the lower part of the feed hopper.

[0021] Preferably, a high-gluten wheat flour preparation process, wherein the equipment used in the high-gluten wheat flour preparation process is the high-gluten wheat flour preparation equipment described above, includes the following steps:

[0022] Step 1, Protein content adjustment: After washing the wheat, dry it until the free water content is 15% to 17%. Take 5 to 10 samples to determine the percentage of protein content in the wheat. If the dry basis protein content is less than 12.2%, add wheat gluten according to the percentage of the total wheat content and mix it evenly with the wheat.

[0023] Step 2: Grinding using high-gluten wheat flour preparation equipment: Wheat mixed with gluten is poured into the frame through the feed hopper. The motor drives the inner grinding ring to rotate through the first pulley, belt, and second pulley. The inner grinding ring rotates within the frame through the support. Wheat and gluten pass between the inner and outer grinding rings. Wheat and gluten pass sequentially through the grinding gap formed between the first grinding surface and the first inner grinding surface, the space formed between the anti-clogging grinding surface and the screening section for screening wheat flour, the grinding gap formed between the second grinding surface and the second inner grinding surface, and the grinding gap formed between the third grinding surface and the third inner grinding surface. When the wheat passes through the screening section, the ground wheat flour enters the collection hopper through the screening section. The wheat flour in the collection hopper then falls directly into the flour drum through the feed pipe. Multiple screening sections are set at the top and bottom to accelerate the screening of the ground wheat flour into the flour drum. Multiple sets of wheat flour grinding and screening result in high wheat flour grinding efficiency.

[0024] Step 3, Anti-clogging: When the inner grinding ring rotates, the first sliding rod causes the outer grinding ring to move up and down within the frame through the first sliding groove of the waveform, so that the first grinding surface and the first inner grinding surface, the anti-clogging grinding surface and the screening section, the second grinding surface and the second inner grinding surface, and the third grinding surface and the third inner grinding surface form an up-and-down movement. When wheat and bran pass through, the movement will accelerate the passage and prevent clogging. The vertical grinding of the first grinding surface and the first inner grinding surface, the second grinding surface and the second inner grinding surface makes the wheat fall quickly, the grinding efficiency is high and the grinding quality is good. The continuous screening makes the wheat and bran grinding and de-drying efficiency high.

[0025] Step 4, Integrated Screening: When the inner grinding ring rotates, the second sliding rod causes the mounting seat to slide up and down around the limit seat through the wave-shaped second sliding groove. When the mounting seat slides up and down, it drives the screen bucket to screen up and down to remove the bran containing wheat flour.

[0026] This invention provides a process for preparing high-gluten wheat flour. It has the following beneficial effects:

[0027] This invention involves taking multiple samples in advance to determine the protein content of wheat. Based on the test results, wheat gluten is added as a percentage according to the total amount of wheat and then mixed evenly to achieve the preparation of high-gluten wheat. This allows the wheat to meet the requirements for high gluten content and enables the direct processing of wheat flour to obtain high-gluten wheat flour.

[0028] This invention combines multiple screening sections with an anti-clogging grinding surface. When the wheat flour separated from the bran after grinding passes through the screening section, the wheat flour that meets the requirements falls from the screening section into the collection hopper, and then directly enters the flour drum through the feeding pipe. This enables timely separation of wheat flour and bran, achieving high screening efficiency. It eliminates the need for separate screening equipment for wheat flour in the future. The wheat flour in the bran is screened by the up-and-down vibration of the mounting base at the bottom of the frame, achieving high wheat flour yield and good bran screening effect.

[0029] This invention combines multiple sets of first grinding surfaces and first inner grinding surfaces, anti-clogging grinding surfaces and sieving sections, second grinding surfaces and second inner grinding surfaces, and third grinding surfaces and third inner grinding surfaces. While sieving wheat flour, it also grinds the wheat flour remaining on the bran. The cross-sections between them are zigzag-shaped, which ensures that the bran and wheat flour are fully and thoroughly ground. The bran does not need to be ground a second time, resulting in high equipment production efficiency and high-quality wheat flour.

[0030] This invention utilizes the rotation of the inner grinding ring. The first sliding rod, through the first groove of the waveform, causes the outer grinding ring to move up and down within the frame via a reset mechanism. This creates a vertical movement between the first grinding surface and the first inner grinding surface, the anti-clogging grinding surface and the screening section, the second grinding surface and the second inner grinding surface, and the third grinding surface and the third inner grinding surface. When wheat and bran pass through, the movement accelerates their passage, preventing blockage. The vertical grinding of the first grinding surface and the first inner grinding surface, as well as the second grinding surface and the second inner grinding surface, ensures fast wheat feeding, high grinding efficiency, and good grinding quality. Continuous screening ensures high efficiency in wheat and bran grinding and desiccation. Wheat flour does not form bridges between the grinding discs and does not clump due to high-temperature cooking. There is no need to disassemble the grinding discs for cleaning, saving time and effort.

[0031] This invention utilizes an internal grinding mechanism and an external grinding mechanism working together, combined with a sieving section, to simultaneously sieve wheat flour and grind the remaining bran, achieving a high yield of wheat flour, minimal bran residue, and excellent grinding effect.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] like Figure 1-9 As shown, an embodiment of the present invention provides a high-gluten wheat flour preparation device, comprising:

[0045] The machine frame 1 has a feed hopper 9 on its top and multiple support legs 2 on its bottom. The feed hopper 9 is used to mix wheat and gluten and feed them into the machine frame 1.

[0046] The screening mechanism 3 is installed in the lower middle part of the frame 1 via the shaking mechanism 10. The screening part 3 is used to screen out the bran containing wheat flour. The shaking mechanism 10 can shake the sieve 303 to separate the bran and wheat flour.

[0047] The outer grinding mechanism 5 is elastically installed in the frame 1 through the reset mechanism 6. The outer grinding mechanism 5 and the inner grinding mechanism 7 cooperate with each other to grind wheat flour.

[0048] The internal grinding mechanism 7 is located inside the external grinding mechanism 5 and is installed in the frame 1 via the drive mechanism 8.

[0049] The outer grinding mechanism 5 includes an outer grinding ring 501, which slides axially within the frame 1. Multiple sets of first grinding surfaces 502, anti-clogging grinding surfaces 503, second grinding surfaces 504, and third grinding surfaces 505, arranged from top to bottom, are provided on the inner side of the outer grinding ring 501. The inner grinding mechanism 7 includes an inner grinding ring 706, with multiple sets of first inner grinding surfaces 701, screening sections 702, second inner grinding surfaces 703, and third inner grinding surfaces 704 arranged from top to bottom on the outer side of the inner grinding ring 706. A discharge cone 705 is provided at the top of the inner grinding mechanism 7, positioned directly below the feed hopper 9, with the gap between the discharge cone 705 and the inner wall of the frame 1 decreasing from top to bottom. The first grinding surface 502 is disposed outside the first inner grinding surface 701 and forms a wheat flour grinding gap between them. The first grinding surface 502 and the first inner grinding surface 701, the second grinding surface 504 and the second inner grinding surface 703 are vertical. A space for sieving wheat flour is formed between the anti-clogging grinding surface 503 and the sieving part 702. The second grinding surface 504 is disposed outside the second inner grinding surface 703 and forms a wheat flour grinding gap between them. The third grinding surface 505 is disposed outside the third inner grinding surface 704 and forms a wheat flour grinding gap between them. Multiple sets of feeding components 4 are arranged from top to bottom on the inner side of the internal grinding mechanism 7. The feeding components 4 include multiple collection hoppers 402 arranged inside each screening section 702. In summary, washed wheat and gluten are fed into the frame 1 through the feed hopper 9. The wheat is dispersed between the inner grinding ring 706 and the outer grinding ring 501 by the discharge cone 701. The motor 802 drives the inner grinding ring 706 to rotate through the first pulley 803, belt 804 and second pulley 805. When the wheat passes through the first grinding surface 502 and the first inner grinding surface 701, it is ground and crushed. The wheat flour falls into the screening section 702. The qualified wheat flour is screened into the collection hopper 402 for the first time. After that, the wheat flour and bran that do not meet the particle size requirements fall sequentially between the second inner grinding surface 703 and the second grinding surface 504, the third inner grinding surface 704 and the third grinding surface 505. The wheat flour on the bran is ground off and the wheat flour is ground into fine powder. Multiple settings can grind wheat flour to the required fineness, and can thoroughly grind the wheat flour on the wheat bran in one go. During grinding, the inner grinding ring 706 causes the outer grinding ring 501 to slide up and down through the first sliding rod 607 and the first sliding groove 606 with a wave pattern. This causes the third grinding surface 505 and the third inner grinding surface 704 to approach and separate from each other, achieving effective grinding of wheat flour. The combination of multiple grinding surfaces that interlock and slide together results in a good wheat grinding effect. The wheat flour sieving section 702 sieves the wheat flour multiple times, reducing the amount of bran and wheat flour falling into the sieve hopper 303. During subsequent sieving, the wheat flour and bran can be quickly separated. The timely separation of wheat flour and bran can prevent wheat flour from affecting the grinding efficiency of bran and residual wheat flour during subsequent grinding, achieving effective sieving and grinding of wheat flour, resulting in a good wheat flour grinding effect.

[0050] The reset mechanism 6 includes multiple stops 601 and multiple limiting rods 602, which are fixed to each other. Multiple first limiting grooves 605 are provided on the outer side of the outer grinding ring 501, and each stop 601 slides within a corresponding first limiting groove 605. A limiting sleeve 603 is fixed within each first limiting groove 605. Each limiting rod 602 slides against its corresponding limiting sleeve 603. A first spring 604 is fixed to one end of each limiting rod 602, and each first spring 604 is located within its corresponding limiting sleeve 603. A wavy first sliding groove 606 is provided around the bottom inner wall of the outer grinding ring 501. A first sliding rod 607 is rotatably connected to the outer bottom of the inner grinding ring 706, and the first sliding rod 607 slides... The outer grinding ring 501, positioned within the first sliding groove 606, slides up and down within the frame 1. It engages with the first limiting groove 605 and the stop block 601, while the limiting rod 602 and the limiting sleeve 603 slide together. Simultaneously, the first spring 604 presses the limiting rod 602 and the limiting sleeve 603 together, ensuring the first spring 604 constantly presses the outer grinding ring 501 downwards. When the first sliding rod 607 and the first sliding groove 606 slide together, causing the outer grinding ring 501 to move up and down, it can engage with the inner grinding ring 706 to grind wheat. This also prevents wheat from clogging the grinding discs, ensuring continuous operation of the equipment.

[0051] The rocking mechanism 10 includes a mounting base 1006 and a limiting base 1003. Multiple limiting bases 1003 are provided on the inner wall of the frame 1. Multiple second limiting grooves 1005 are provided on the outer side of the mounting base 1006. Each limiting base 1003 slides within a corresponding second limiting groove 1005. A second spring 1004 is provided within each second limiting groove 1005, and the second spring 1004 elastically compresses the corresponding limiting base 1003. A wave-shaped second sliding groove 1002 is provided around the inner circumference of the mounting base 1006. A second sliding rod 1001 slides inside the inner grinding ring 706. The second sliding rod 1001 rotates on one side of the bottom of the inner grinding ring 706. When the inner grinding ring 706 rotates, the second sliding rod 1001 moves the second sliding groove 1002 on the mounting base 1006, causing the mounting base 1006 to drive the sieve bucket 303 to move up and down, thereby achieving the sieving of bran and wheat flour. The second spring 1004 enables the mounting base 1006 to always move downward elastically, which, combined with the wave-shaped second sliding groove 1002, achieves the upper and lower limit movement of the mounting base 1006.

[0052] The screening mechanism 3 includes a flour bin 301, a skirt 302, and a sieve 303. The sieve 303 is detachably installed at the bottom of the mounting base 1006. A screen is provided at the bottom of the sieve 303, and a skirt 302 is installed on the outer periphery of the bottom of the sieve 303. The flour bin 301 is located directly below the sieve 303. The bottom of the lowest collecting hopper 402 is connected to a feeding pipe 401. The lower part of the feeding pipe 401 passes through the sieve 303 and extends outward. After the feeding pipe 401 collects the ground wheat flour, it is poured directly into the flour bin 301, realizing simultaneous grinding and screening during the wheat flour grinding process, and achieving the collection of wheat flour. The skirt 302 can block the wheat flour and prevent it from scattering.

[0053] The drive mechanism 8 includes a drive box 801 and a motor 802. The drive box 801 is mounted on the frame 1, and the motor 802 is mounted inside the drive box 801. A first pulley 803 is fixed to the drive end of the motor 802. The top of the inner grinding ring 706 is mounted on the lower part of the feed hopper 9 of the frame 1 through a bracket. A second pulley 805 is fixed to the top of the inner grinding ring 706. The first pulley 803 is connected to the second pulley 805 through a belt 804. Both the first pulley 803 and the second pulley 805 are mounted inside the drive box 801. One end of the drive box 801 extends to the lower part of the feed hopper 9. The drive box 801 occupies a part of the feed hopper 9 and will not cause the feed hopper 9 to be blocked. At the same time, the inner grinding ring 706 is mounted inside the frame 1 through a bracket.

[0054] Example 2:

[0055] Reference Figures 1-9 As shown, this embodiment of the invention provides a process for preparing high-gluten wheat flour. The equipment used in this process is the high-gluten wheat flour preparation equipment described above, and includes the following steps:

[0056] Step 1, Protein content adjustment: After washing the wheat, dry it until the free water content is 15% to 17%. Take 5 to 10 samples to determine the percentage of protein content in the wheat. If the dry basis protein content is less than 12.2%, add wheat gluten according to the percentage of the total wheat content and mix it evenly with the wheat.

[0057] Step 2: Grinding using high-gluten wheat flour preparation equipment: Wheat mixed with gluten is poured into the frame 1 through the feed hopper 9. Motor 802 drives the inner grinding ring 706 to rotate via the first pulley 803, belt 804, and second pulley 805. The inner grinding ring 706 rotates within the frame 1 via a support. Wheat and gluten pass between the inner grinding ring 706 and the outer grinding ring 501. The wheat and gluten sequentially pass through the grinding gap formed between the first grinding surface 502 and the first inner grinding surface 701, the anti-clogging grinding surface 503, and the sieving section 702, forming a space for sieving wheat flour. The space, the second grinding surface 504 and the second inner grinding surface 703 form a wheat flour grinding gap with each other, and the third grinding surface 505 and the third inner grinding surface 704 form a wheat flour grinding gap with each other. When the wheat passes through the sieving section 702, the ground wheat flour will enter the collection hopper 402 through the sieving section 702. The wheat flour in the collection hopper 402 will then fall directly into the flour drum 301 through the feeding pipe 401. Multiple sieving sections 702 are set at the top and bottom to accelerate the sieving of the ground wheat flour into the flour drum 301. Multiple sets of wheat flour grinding and sieving result in high wheat flour grinding efficiency.

[0058] Step 3, Anti-clogging: When the inner grinding ring 706 rotates, the first sliding rod 607 causes the outer grinding ring 501 to move up and down within the frame 1 via the first wave-shaped sliding groove 606. This creates an up-and-down motion between the first grinding surface 502 and the first inner grinding surface 701, the anti-clogging grinding surface 503 and the screening section 702, the second grinding surface 504 and the second inner grinding surface 703, and the third grinding surface 505 and the third inner grinding surface 704. When wheat and bran pass through, the movement accelerates the passage and prevents clogging. The vertical grinding of the first grinding surface 502 and the first inner grinding surface 701, the second grinding surface 504 and the second inner grinding surface 703 ensures fast wheat feeding, high grinding efficiency, and good grinding quality. Continuous screening ensures high efficiency in wheat and bran grinding and desiccation.

[0059] Step 4, Integrated Screening: When the inner grinding ring 706 rotates, the second slide rod 1001 causes the mounting seat 1006 to slide up and down around the limiting seat 1003 through the wave-shaped second slide groove 1002. When the mounting seat 1006 slides up and down, the mounting seat 1006 drives the screen bucket 303 to screen up and down the bran containing wheat flour.

4. The high-gluten wheat flour preparation equipment according to claim 3, characterized in that: The drive mechanism (8) includes a drive box (801) and a motor (802). The drive box (801) is mounted on the frame (1). The motor (802) is mounted inside the drive box (801). A first pulley (803) is fixed to the drive end of the motor (802). The top of the inner grinding ring (706) is mounted on the lower part of the feed hopper (9) of the frame (1) through a bracket. A second pulley (805) is fixed to the top of the inner grinding ring (706). The first pulley (803) is connected to the second pulley (805) through a belt (804). The first pulley (803) and the second pulley (805) are both mounted inside the drive box (801). One end of the drive box (801) extends to the lower part of the feed hopper (9).

5. A process for preparing high-gluten wheat flour, wherein the equipment used in the process is the high-gluten wheat flour preparation equipment described in claim 4, characterized in that: Includes the following steps: Step 1, Protein content adjustment: After washing the wheat, dry it until the free water content is 15% to 17%. Take 5 to 10 samples to determine the percentage of protein content in the wheat. If the dry basis protein content is less than 12.2%, add wheat gluten according to the percentage of the total wheat content and mix it evenly with the wheat. Step 2: Grinding using high-gluten wheat flour preparation equipment: Wheat mixed with gluten is poured into the frame (1) through the feed hopper (9). The motor (802) drives the inner grinding ring (706) to rotate through the first pulley (803), belt (804), and second pulley (805). The inner grinding ring (706) rotates within the frame (1) through the support. Wheat and gluten pass between the inner grinding ring (706) and the outer grinding ring (501). Wheat and gluten pass sequentially through the grinding gap formed between the first grinding surface (502) and the first inner grinding surface (701), the anti-clogging grinding surface (503), and the sieving section (702) to form a sieving area for small particles. The space of wheat flour, the second grinding surface (504) and the second inner grinding surface (703) form a wheat flour grinding gap with each other, and the third grinding surface (505) and the third inner grinding surface (704) form a wheat flour grinding gap with each other. When the wheat passes through the sieving section (702), the ground wheat flour will enter the collection hopper (402) through the sieving section (702). The wheat flour in the collection hopper (402) will then fall directly into the flour bucket (301) through the feed pipe (401). Multiple sieving sections (702) are set at the top and bottom to accelerate the sieving of the ground wheat flour into the flour bucket (301). Multiple sets of wheat flour grinding and sieving result in high wheat flour grinding efficiency. Step 3, Anti-clogging: When the inner grinding ring (706) rotates, the first slide rod (607) causes the outer grinding ring (501) to move up and down in the frame (1) through the first slide groove (606) of the waveform, so that the first grinding surface (502) and the first inner grinding surface (701), the anti-clogging grinding surface (503) and the screening part (702), the second grinding surface (504) and the second inner grinding surface (703), the third grinding surface (505) and the third inner grinding surface (704) form an up and down movement. When wheat and bran pass through, the movement will accelerate the passage and there will be no blockage. The vertical grinding of the first grinding surface (502) and the first inner grinding surface (701), the second grinding surface (504) and the second inner grinding surface (703) makes the wheat fall quickly, the grinding efficiency is high and the grinding quality is good. The continuous screening makes the wheat and wheat bran grinding and de-drying efficiency high. Step 4, Integrated Screening: When the inner grinding ring (706) rotates, the second sliding rod (1001) causes the mounting seat (1006) to slide up and down around the limiting seat (1003) through the wave-shaped second sliding groove (1002). When the mounting seat (1006) slides up and down, the mounting seat (1006) drives the screen bucket (303) to screen up and down the bran containing wheat flour.
