TECHNICAL FIELD
[0001] The utility model belongs to the technical field of wheat flour processing equipment, specifically is a flour processing is with the back powder compound grinding device. BACKGROUND
[0002] In the flour production process, "flour back powder" is a very important link concept. After grinding and screening, some flour particles that do not meet the particle size requirements of finished flour will be separated out. These particles are relatively coarse or fine, and cannot be directly packaged and sold as qualified finished flour. In the actual production process, the reason for the fine flour is that the gap between the grinding discs is too small, and the reason for the coarse flour is that the wheat is too hard. Generally speaking, coarse flour particles will be sent back to the mill for regrinding, but through repeated tests, it is found that the main reason for the coarse flour particles is that some wheat particles are relatively hard, and simple regrinding cannot solve the problem of coarse flour particles. However, after heating these flour particles to 70 DEG C for a period of time, they can be easily ground. Therefore, a device is needed to solve the problem of coarse flour particles to meet the needs. SUMMARY
