Description

Technical Field

[0001] This utility model relates to the field of flour production technology, specifically to a flour milling mechanism. Background Technology

[0002] Flour is a powdery substance made from wheat. Based on the amount of protein in flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. Flour (wheat flour) is a staple food in most parts of northern China. In the production process, wheat needs to be ground to obtain the required flour.

[0003] Currently, conventional flour milling machines only have a grinding function, which requires a lot of time to grind whole wheat grains, and the grinding quality is poor. During the flour grinding process, the temperature of the grinding disc will rise. If the grinding disc temperature is too high, it will heat the flour, causing the flour to deteriorate and affecting its normal use later. Therefore, we propose a flour milling machine to solve the above problems. Utility Model Content

A cooling mechanism 10 is fixedly installed on the right side of the tank 1, and the cooling mechanism 10 is connected to the right side wall of the tank 1 and the air distribution box 3.

[0017] like Figure 2 As shown, in some embodiments, the drive mechanism 4 includes a motor 401, a transmission pipe 402, an air inlet 403, and a first mechanical seal 404. The motor 401 is fixedly installed on the upper surface of the air distribution box 3. The transmission pipe 402 is fixedly installed on the lower surface of the output shaft of the motor 401. The lower surface of the transmission pipe 402 is an open structure, and the transmission pipe 402 is movably inserted into the tank body 1. The transmission pipe 402 has an air inlet 403 on the front side wall inside the air distribution box 3. The first mechanical seal 404 is provided on the upper and lower side walls of the air distribution box 3 and the upper side wall of the tank body 1 corresponding to the transmission pipe 402.

[0018] In this embodiment, the output shaft of the motor 401 can drive the transmission tube 402 to rotate, the first mechanical seal 404 improves the stability and sealing of the transmission tube 402, and the air inlet 403 allows the cold air in the air distribution box 3 to flow into the transmission tube 402.

[0019] like Figure 2 As shown, in some embodiments, the crushing mechanism 5 includes a grid plate 501, crushing blades 502 and through holes 503. The grid plate 501 is fixedly installed on the inner wall of the tank 1 near the upper side. Crushing blades 502 are evenly arranged on the transmission pipe 402 on the upper side of the grid plate 501. Through holes 503 are opened on the grid plate 501 at positions corresponding to the transmission pipe 402.

[0020] In this embodiment, whole wheat falls onto the grid plate 501, and the crushing blade 502 rotates with the transmission tube 402, causing the crushing blade 502 to crush the whole wheat. The crushed wheat then falls into the guide bucket 6 through the grid plate 501.

[0021] like Figure 4As shown, in some embodiments, the grinding mechanism 7 includes a movable grinding disc 701, a fixed grinding disc 702, a second mechanical seal 703, an air distribution chamber 704, an air outlet 705, and a fixing rod 706. The movable grinding disc 701 is fixedly installed on the outer surface of the transmission tube 402 near the lower side. The fixed grinding disc 702 is installed on the lower end of the transmission tube 402 through the second mechanical seal 703. An air distribution chamber 704 is opened in the fixed grinding disc 702 corresponding to the lower surface of the transmission tube 402. An air outlet 705 is evenly opened circumferentially on the side wall of the fixed grinding disc 702 corresponding to the air distribution chamber 704. A fixing rod 706 is evenly fixedly installed circumferentially between the lower surface of the fixed grinding disc 702 and the inner wall of the tank 1.

[0022] In this embodiment, the movable grinding disc 701 rotates with the transmission pipe 402, so that the movable grinding disc 701 and the fixed grinding disc 702 grind the crushed wheat. The cold air in the transmission pipe 402 flows into the air distribution chamber 704 and then flows out through the air outlet 705, thereby achieving the effect of cooling the movable grinding disc 701 and the fixed grinding disc 702. The fixing rod 706 fixes the fixed grinding disc 702.

[0023] like Figure 4 As shown, in some embodiments, a guide pipe 11 is fixedly installed on the upper surface of the movable grinding disc 701, and the guide pipe 11 is movably inserted into the outlet of the guide bucket 6. A guide channel 12 is opened around the transmission pipe 402 on the upper surface of the movable grinding disc 701.

[0024] In this embodiment, the guide pipe 11 allows the crushed wheat to flow into the guide channel 12, so that the crushed wheat flows through the guide channel 12 between the lower surface of the movable grinding disc 701 and the upper surface of the fixed grinding disc 702.

[0025] like Figure 1 As shown, in some embodiments, a rectangular opening 13 is provided on the left side wall of the tank 1 corresponding to the vibrating screen assembly 9.

[0026] In this embodiment, the rectangular opening 13 allows the vibrating screen assembly 9 to extend so that flour and wheat bran can be discharged.

[0027] like Figure 2 As shown, in some embodiments, the refrigeration mechanism 10 includes an exhaust fan 101, a semiconductor refrigeration box 102, an air filter 103, and a conduit 104. The exhaust fan 101, the semiconductor refrigeration box 102, and the air filter 103 are fixedly installed on the right side of the tank body 1 from top to bottom. The air distribution box 3, the exhaust fan 101, the semiconductor refrigeration box 102, the air filter 103, and the right side wall of the tank body 1 are connected in series through the conduit 104.

[0028] In this embodiment, the exhaust fan 101 draws air from the semiconductor cooling box 102 and the air filter 103 through the conduit 104, so that the gas in the tank 1 flows into the air filter 103 and is filtered to prevent flour from entering. The air is cooled by the semiconductor cooling box 102, and the cooled gas flows into the air distribution box 3 through the conduit 104.

[0029] In use, wheat to be ground is poured into tank 1 through feeding hopper 2. The whole wheat falls onto the upper surface of grid plate 501 in crushing mechanism 5. Then, the output shaft of motor 401 in drive mechanism 4 drives transmission tube 402 to rotate, causing crushing blade 502 to rotate with transmission tube 402, thus crushing the whole wheat. The crushed wheat falls into guide hopper 6 through grid plate 501, and then flows to movable grinding disc 701 in grinding mechanism 7 through guide hopper 6. The crushed wheat flows through guide channel 12 between the lower surface of movable grinding disc 701 and the upper surface of fixed grinding disc 702. Movable grinding disc 701 rotates with transmission tube 402, and the movable grinding disc 701 and fixed grinding disc 702 grind the crushed wheat. After grinding, the wheat falls onto guide plate 8, and flows into vibrating screen assembly 9 through guide plate 8. Vibrating screen assembly 9 feeds flour. The flour is sieved to separate and discharge the bran. During the grinding process, the exhaust fan 101 in the refrigeration unit 10 draws air from the semiconductor refrigeration box 102 and the air filter 103 through the conduit 104, causing the gas in the tank 1 to flow into the air filter 103 for filtration, preventing flour from entering. The semiconductor refrigeration box 102 cools the air, and the cooled gas flows into the air distribution box 3 through the conduit 104. The cold air in the air distribution box 3 flows into the transmission pipe 402 through the air inlet 403, and then into the air distribution chamber 704 through the transmission pipe 402. The air distribution chamber 704 cools the fixed grinding disc 702, and the cold air is blown out through the air outlet 705, cooling both the movable grinding disc 701 and the fixed grinding disc 702. This effectively prevents the flour from being heated and deteriorated during high-temperature grinding by the movable grinding disc 701 and the fixed grinding disc 702, ensuring the quality of the ground flour and facilitating its later use.

[0030] In summary, this flour milling mechanism, through the drive mechanism 4 driving the crushing mechanism 5 to rotate, can crush wheat. The crushed wheat is then ground by the grinding mechanism 7, which can improve grinding efficiency and quality, increase the cooling function of the grinding mechanism 7 inside the tank 1, effectively prevent the flour from being heated and deteriorated by the grinding mechanism 7, ensure the quality of flour grinding, and facilitate its later use.
