All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the present utility model provides the following technical solutions: a starch production part with a crushing function comprises a crushing static disc, wherein the crushing static disc comprises a crushing cavity 1, an air outlet 3 and crushing teeth 5; wherein,,

crushing cavity 1 is connected with air outlet 3, and crushing tooth 5 is arranged on crushing cavity 1's outer lane inner wall in succession, and crushing tooth 5 has also been arranged to air outlet 3's inboard one end.

Specifically, firstly, a distribution moving disc 7 for generating centrifugal force and wind pressure is installed in the crushing cavity 1, the moving disc is composed of a circular front baffle 703, a rear baffle 701 and a middle arc or straight distribution blade 702, so that a plurality of closed channels (as shown in fig. 3) are formed, holes in the middle of the front baffle 703 are a feeding air inlet 704, and the rear baffle 701 is fixed with a transmission shaft, so that the whole distribution moving disc 7 can be conveniently driven to rotate.

The variable frequency motor is utilized to drive the distribution moving plate 7 to rotate, stronger centrifugal force and wind pressure are generated through the distribution blades 702 (negative pressure is formed at the center of the distribution moving plate 7, high pressure is formed at the outer side of the distribution moving plate 7), stronger suction force is generated through the feeding air inlet 704 of the distribution moving plate 7 to the outside, so that materials are sucked into the center of the distribution moving plate 7, the materials are scattered and fly outwards along a plurality of closed channels formed by the distribution blades 702 under the combined action of centrifugal acceleration and internal and external pressure difference of the distribution moving plate 7, the materials are impacted at high speed to the windward surfaces of a plurality of groups of crushing teeth 5 on the side wall of the crushing cavity 1, so that the materials are crashed to form more rebound small particles, the small particles are pushed by the follow-up materials and wind pressure medium to continuously impact the crushing teeth 5 in the cavity for a plurality of times, so as to form smaller particle powder, the powder is carried out from the air outlet 3 to the next procedure, the crushing teeth 5 are also arranged on the inner wall of the outer side of the air outlet 3, thus ensuring that the crushing teeth 5 crush the materials in all aspects from entering the crushing cavity 1 to moving out, avoiding omission, the designed position of the air outlet 3 is strictly required according to the direction generated by air pressure, when the distribution moving disc 7 rotates clockwise, the air outlet 3 is arranged on the left side along the tangent line of the crushing cavity 1, when the distribution moving disc rotates anticlockwise, the air outlet 3 is ensured to send the materials out along the air pressure on the right side, thereby realizing the efficient crushing of the materials, the fineness of the finished products can be controlled through the rotating frequency of the distribution moving disc 7 in the actual production process, the rotating frequency, namely the air pressure influences the kinetic energy of each material particle, and the impact times of the materials in the crushing cavity 1 can be influenced, thereby adjusting the fineness of the final product.

The materials are continuously pushed to collide with the crushing teeth 5 and rebound by utilizing wind pressure, and the materials are repeatedly crushed into powder, so that the crushing effect is good. The fine particle powder can be obtained without sieving the screen, the screen structure is removed, and cleaning and maintenance of the screen are not needed, so that time and labor are saved;

the crushing process saves a large amount of water resources, steam energy consumption and labor force, the fineness of the finished product can be controlled according to the speed of driving the distribution movable plate 7 by the variable frequency motor and the feeding speed, and the crushing process is suitable for rice, glutinous rice, peeled corn, various grains rich in starch, potatoes with the size smaller than 1 cm and the like;

taking rice flour as an example, the water content of the rice is increased from 14% to 22% -24% after the rice is moistened, the diameter of a cloth moving disc 7 of a pulverizer is 800mm, and the rotating speed is 2900 rpm; in the production process, the speed of the rice leaving the outer side of the distribution movable disc 7 to strike the windward side of the crushing teeth 5 is 121.4 m/s, and the pressure is 12000Pa; after primary crushing, the powder fineness is 89% in 100 mesh passing rate, 72% in 200 mesh passing rate and 18.6% in water;

the effects of energy conservation, consumption reduction and emission reduction are as follows: compared with the traditional water milling process (the grinding process with the quality of the formed starch being relatively close), the water milling process uses 5-6 tons of water per ton of finished products, generates waste water (COD 6000-8000 or more, needs to be treated), uses 90-110 DEG, uses steam for drying (200 kg of 6000 large-calorie standard coal), and the process only adopts a rice wetting process, uses 100-200 kg of water per ton of finished products (no emission in absorption), uses 50-60 DEG, and does not use steam (the air quantity in the production process is regulated to control the water).

The arrangement area of the crushing teeth 5 accounts for 50% -100% of the inner wall of the outer ring of the crushing cavity 1, the angle of the crushing teeth 5 is 60-150 degrees, the crushing teeth 5 are continuously and evenly arranged on the side wall of the inner ring of the crushing cavity 1, the arrangement area of the crushing teeth 5 accounts for the total area of the side wall of the inner ring, the ratio of the crushing teeth 5 on the inner side of the crushing cavity 1 is 50% -100% so that materials can form multiple continuous impacts, the crushing effect is not ideal if the ratio of the crushing teeth 5 is less than 50%, the crushing teeth are continuously arranged on the side wall of the inner ring from bottom to top, the angular tips of the crushing teeth 5 can be set to sharp angles or obtuse angles, and the difference is not too great.

Through experiments, the angle of the crushing teeth 5 is between 60 degrees and 150 degrees, so that a good windward crushing surface can be formed, the crushing effect can be ensured, the higher the tooth distribution rate is, the higher the crushing effect is, the higher the fineness of the finished product is, but the processing efficiency is low, otherwise, the tooth distribution rate is low, the processing efficiency is high, the fineness is general, and the automatic selection can be realized according to the process requirements;
