Description

Technical Field

[0001] The utility model relates to the technical field of flour production and processing, in particular to a flour grinding device for flour production. Background Technique

[0002] Flour is a powdery substance ground from wheat. According to the protein content in the flour, it can be divided into high-gluten flour, medium-gluten flour, low-gluten flour and gluten-free flour. A flour grinding device is required during the process of grinding wheat into flour.

[0003] A flour production grinding machine disclosed in Chinese Patent CN220573608U includes a grinding cylinder. A grinding motor is arranged at the upper end of the grinding cylinder, a grinding disc is arranged at the lower end of the grinding motor, a screening box is arranged at the lower end of the grinding cylinder, a bran sieve is arranged inside the screening box, a flour collection box is slidably connected below the bran sieve, an impurity filtering component is arranged at one side of the upper end of the grinding cylinder, and a bran cleaning component is slidably connected to the surface of the bran sieve.

[0004] However, compared with the prior art and the comparison scheme, the following problems still exist in the actual use of this flour production grinding machine:

[0005] In the prior art, before grinding wheat into flour, it is generally necessary to adjust the moisture of wheat (moisture adjustment means soaking wheat for a certain time first, so that the outer skin of wheat absorbs moisture, and then grinding. The main purpose of moisture adjustment is to make wheat fully absorb water and promote grinding. In addition, appropriate moisture adjustment can also prevent wheat from being over-ground and maintain the quality of flour). When the wheat after moisture adjustment is ground, due to the relatively high moisture content of the bran, it is easy to adhere to the grinding area of the grinding disc and the grinding cylinder, affecting the grinding effect. And after the grinding is completed, without the entry of subsequent wheat, the bran adhering to the grinding area of the grinding disc and the grinding cylinder is not easy to be cleaned off, which will affect the next grinding.

[0039] As Figure 1 、 Figure 4 and Figure 5 shown, the second grinding cylinder 3 includes a conical crushing area 301 and a cylindrical grinding area 302. A first gear 303 is fixedly connected to the top of the crushing area 301.

[0042] The working process is as follows:

[0043] S1. During use, the wheat to be ground into flour is added from the feed hopper 102 between the first flour grinding cylinder 1 and the crushing area 301. The driving member 2 is started to rotate forward. The driving member 2 drives the connecting pipe 202 through the transmission rod 201. The slider 305 slides in the chute 204, and the second toothed ring 203 rotates in the connecting groove 307.

[0044] S2. The second toothed ring 203 drives the third gear 323 to rotate, and the third gear 323 drives the auxiliary roller 32 to rotate, so that the grinding semi-roller 321 faces outside the storage groove 306. At this time, the slider 305 slides to the end of one end of the chute 204. The connecting pipe 202 drives the connecting column 304 to rotate through the slider 305, and the connecting column 304 drives the second flour grinding cylinder 3 to rotate.

[0045] S3. The second flour grinding cylinder 3 drives the second gear 311 through the first gear 303. The second gear 311 rotates around the first gear 303 and rotates itself under the drive of the first gear 303 and the limit of the first toothed ring 105. The second gear 311 that rotates around the first gear 303 and rotates itself drives the crushing piece 313 to rotate through the connecting shaft 312, and preliminarily crushes the wheat located between the first flour grinding cylinder 1 and the crushing area 301.

[0046] S4. The crushed wheat falls along the conical crushing area 301 between the grinding area 302 and the first flour grinding cylinder 1. The grinding semi-roller 321 leaking from the storage groove 306 assists the grinding area 302 and the first flour grinding cylinder 1 to grind the wheat.

[0047] S5. The flour and bran mixture after grinding falls on the sieve 107. The bran is blocked by the sieve 107 and discharged from the first discharge port 103 along the sieve 107. The flour passes through the sieve 107 and is discharged from the bottom of the first flour grinding cylinder 1 along the second discharge port 104.

[0048] S6. After the flour grinding is completed, the driving member 2 is started to rotate reversely. The driving member 2 drives the connecting pipe 202 through the transmission rod 201. The slider 305 slides in the chute 204, and the second toothed ring 203 rotates in the connecting groove 307. The second toothed ring 203 drives the third gear 323 to rotate, and the third gear 323 drives the auxiliary roller 32 to rotate, so that the cleaning semi-roller 322 faces outside the storage groove 306. At this time, the slider 305 slides to the end of the other end of the chute 204. The connecting pipe 202 drives the connecting column 304 to rotate through the slider 305, and the connecting column 304 drives the second flour grinding cylinder 3 to rotate.

[0049] S7. The second grinding cylinder 3 drives the cleaning semi-roller 322 to clean the area inside the first grinding cylinder 1 corresponding to the grinding area 302, removing the attached bran. The removed bran falls on the screen 107 and is discharged from the first discharge port 103 along the screen 107, preventing it from affecting the next grinding operation.
