Problems solved by technology
In actual production, the bran rotates under the drive of the beating board to generate centrifugal force. The bran with large mass has a large centrifugal force and can be in contact with the sieve and separated from the flour, but the bran and flour with lighter weight are mostly in the center of rotation. position, it is difficult to contact with the sieve, this part of the flour cannot be separated from the bran, resulting in a low flour extraction rate

Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0023] Such as figure 1 As shown, a double-screen bran beating machine includes a casing 1, a feeding pipeline 2, a discharge port 3, a screening mechanism 4, a driving motor 5 and an induced draft fan 6.
[0024] The screening mechanism 4 is arranged inside the casing 1 along the length direction of the casing 1 ; the feeding pipeline 2 is arranged on one side of the casing 1 .
[0025] refer to image 3 The screening mechanism 4 includes a coaxially arranged rotating shaft 41, an inner screen 42 and an outer screen 43. The rotating shaft 41 is provided with a plurality of beating plates 44 that rotate synchronously with the rotating shaft 41. 5 said beating boards 44 are provided; the sieve hole diameter of the said i...

The invention discloses a double screen cloth bran finisher. The bran finisher comprises a finisher shell, a material inlet pipeline is arranged on one side of the finisher shell, and a discharge hole is formed in the lower portion of the finisher shell; a screening mechanism is arranged in the length direction of the finisher shell, the screening mechanism comprises a rotating shaft, inner screen cloths and an outer screen cloth which are coaxially arranged, and a plurality of hit plates which synchronously rotate with the rotating shaft are arranged on the rotating shaft; the hit plates are arranged in the outer screen cloth, the inner screen cloths are arranged between the rotating shaft and the outer screen cloth, and a driving motor is connected to one side of the rotating shaft; the material inlet pipeline is connected to one side of the rotating shaft and transmits materials between the inner screen cloths and the outer screen cloth, a draught fan is arranged on the other side of the rotating shaft, and the draught fan acts on cavities between the inner screen cloths and the rotating shaft. The double screen cloth bran finisher has the advantages that the inner screen cloths are adopted, so that the flour extraction rate is effectively improved, and the finisher has good popularization value.
Description
technical field [0001] The invention relates to grain processing machinery, in particular to a double-screen bran beating machine. Background technique [0002] When the flour mill processes wheat, some flour will stick to the bran after screening. At present, the common way to deal with it is to transport the bran to the bran beater. There are rotating beating plates in the bran beater. The flour attached to the bran is beaten down. In actual production, the bran rotates under the drive of the beating board to generate centrifugal force. The bran with large mass has a large centrifugal force and can be in contact with the sieve and separated from the flour, but the bran and flour with lighter weight are mostly in the center of rotation. position, it is difficult to contact with the sieve, and this part of the flour cannot be separated from the bran, resulting in a low flour extraction rate. Contents of the invention [0003] The technical problem to be solved by the pre...
