[0001] The invention relates to the technical field of wheat flour processing, in particular to a preparation process of high-gluten wheat flour. Background Art

[0002] In the current wheat flour processing and preparation process, when the gluten content of wheat flour is insufficient, gluten is mixed with wheat flour to make the wheat flour meet the high gluten requirements; In the existing wheat flour processing and preparation process, wheat flour grinding equipment is usually used to grind wheat flour and bran and then screen them, which is inefficient. In the existing wheat flour processing and preparation process, wheat flour and bran are ground and sieved together. In the subsequent grinding process, the bran with wheat flour wraps around the ground wheat flour, resulting in poor shedding effect of wheat flour. The ground wheat flour needs to be ground again, which affects the production efficiency of the equipment. In the existing wheat flour processing and preparation process, long-term operation of the equipment will cause material to be blocked between the grinding discs. Over time, the wheat flour will form bridges or become hardened due to the high grinding temperature. The grinding discs need to be disassembled and cleaned separately, which is time-consuming and labor-intensive. In the existing wheat flour processing and preparation process, the wheat flour grinding effect is not good. If there is a lot of wheat flour remaining on the bran, secondary grinding is required.

[0013] 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, comprises the following steps: Step 1: Adjust the protein content: Wash the wheat and dry it in the air. The free water content is between 15% and 17%. Take 5 to 10 samples to measure the protein content of the wheat. If the dry protein content is less than 12.2%, add gluten according to the total amount of wheat and mix it with the wheat. The second step is to use the high-gluten wheat flour preparation equipment to grind the wheat: the 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, the belt and the second pulley, the inner grinding ring rotates in the frame through the bracket, the wheat and gluten pass through the inner grinding ring and the outer grinding ring, the wheat and gluten pass through the grinding gap formed by the first grinding surface and the first inner grinding surface, the space for screening wheat flour is formed between the anti-blocking grinding surface and the screening part, the wheat flour grinding gap is formed between the second grinding surface and the second inner grinding surface, and the wheat flour grinding gap is formed between the third grinding surface and the third inner grinding surface. When the wheat passes through the screening part, the ground wheat flour will pass through the screening part into the collecting bucket, and the wheat flour in the collecting bucket will directly fall into the noodle barrel through the discharge pipe. Multiple screening parts are arranged at the upper and lower parts to accelerate the screening of the ground wheat flour and fall into the noodle barrel. Multiple groups of wheat flour are ground and screened, and the wheat flour grinding efficiency is high. Step 3, anti-blocking: when the inner grinding ring rotates, the first slide bar causes the outer grinding ring to move up and down in the frame through the reset mechanism through the first waveform slide groove, so that an up and down movement is formed between the first grinding surface and the first inner grinding surface, the anti-blocking grinding surface and the screening part, 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, they will be accelerated due to the movement and will not be blocked.

[0014] The present invention provides a process for preparing high-gluten wheat flour. It has the following beneficial effects: The present invention measures the protein content in wheat by sampling multiple times in advance, and then adds gluten in percentage according to the measurement results based on the total amount of wheat, and then mixes the gluten with the wheat evenly, so as to achieve high-gluten preparation of wheat. While making the wheat meet the high-gluten requirements, high-gluten wheat flour can be obtained by directly processing wheat flour.

[0015] The present invention combines multiple groups of screening parts with anti-blocking grinding surfaces. When the wheat flour separated from the bran after grinding passes through the screening part, the wheat flour that meets the requirements falls into the collecting bucket from the screening part, and then directly enters the flour barrel through the discharge pipe. The wheat flour and bran are separated in time, and the screening efficiency is high. There is no need to use a separate screening device to screen the wheat flour separately subsequently. The wheat flour in the bran is screened by the mounting base vibrating up and down at the bottom of the frame, so that the wheat flour yield is high and the bran screening effect is good.

[0016] The present invention combines multiple groups of first grinding surfaces and first inner grinding surfaces, anti-blocking grinding surfaces and screening parts, second grinding surfaces and second inner grinding surfaces, and third grinding surfaces and third inner grinding surfaces. Wheat flour is screened while wheat flour remaining on bran is ground. The cross-sections between them are in the shape of broken lines, so that the bran and wheat flour can be fully and thoroughly ground. The bran does not need to be ground twice. The equipment has high production efficiency and produces high-quality wheat flour.

[0017] The present invention rotates the inner grinding ring, and the first sliding rod passes through the first waveform sliding groove to make the outer grinding ring move up and down in the frame through the reset mechanism, so that an up and down movement is formed between the first grinding surface and the first inner grinding surface, the anti-blocking grinding surface and the screening part, 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, they will be accelerated due to the movement and no blockage will occur. 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 uninterrupted screening makes the wheat and bran grinding and de-flouring efficiency high. The wheat flour will not form a bridge between the grinding discs, and will not clump due to high-temperature maturation. There is no need to disassemble the grinding discs for cleaning, which saves time and effort.

[0018] The invention achieves high wheat flour grinding yield, less bran residue, good wheat flour grinding effect and high yield by cooperating with the inner grinding mechanism and the outer grinding mechanism in combination with the screening part, so as to screen the wheat flour while grinding the remaining bran.

10. 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 any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Adjust the protein content: Wash the wheat and dry it in the air. The free water content is between 15% and 17%. Take 5 to 10 samples to measure the protein content of the wheat. If the dry protein content is less than 12.2%, add gluten according to the total amount of wheat and mix it with the wheat. Step 2: Grinding wheat flour using a high-gluten wheat flour preparation device: Pour wheat mixed with gluten 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), the belt (804) and the second pulley (805), the inner grinding ring (706) rotates in the frame (1) through the bracket, and the wheat and gluten pass between the inner grinding ring (706) and the outer grinding ring (501), and the wheat and gluten pass through the grinding gap formed between the first grinding surface (502) and the first inner grinding surface (701), and the anti-blocking grinding surface (503) and the screening part (702) to form a small screening gap. The space for wheat flour, the second grinding surface (504) and the second inner grinding surface (703) form a wheat flour grinding gap, and the third grinding surface (505) and the third inner grinding surface (704) form a wheat flour grinding gap. When the wheat passes through the screening part (702), the ground wheat flour will pass through the screening part (702) and enter the collecting bucket (402). The wheat flour in the collecting bucket (402) then directly falls into the noodle barrel (301) through the discharge pipe (401). The upper and lower parts are provided with multiple screening parts (702) to accelerate the screening of the ground wheat flour and let it fall into the noodle barrel (301). Multiple groups of wheat flour are ground and screened, and the wheat flour grinding efficiency is high. Step 3, anti-blocking: when the inner grinding ring (706) rotates, the first slide bar (607) causes the outer grinding ring (501) to move up and down in the frame (1) through the reset mechanism (6) through the corrugated first slide groove (606), so that an up and down movement is formed between the first grinding surface (502) and the first inner grinding surface (701), the anti-blocking grinding surface (503) and the screening part (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, they are accelerated due to the movement and no blockage occurs. The grinding of the vertical 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 drop fast, the grinding efficiency high, and the grinding quality good. The uninterrupted screening makes the wheat and bran grinding and de-surfacing efficiency high. Step 4: Integrated screening: When the inner grinding ring (706) rotates, the second slide bar (1001) causes the mounting seat (1006) to slide up and down around the limiting seat (1003) through the wavy second slide groove (1002). When the mounting seat (1006) slides up and down, the mounting seat (1006) drives the screening bucket (303) to sieve the bran with residual wheat flour up and down.
