Further, in step 4, the flour processed by the magnetic separator can be selectively diffused and canned.

Further, in the step 1, the flour is divided into five types according to the front powder, the front middle powder, the middle rear powder and the rear powder.

The invention has the following beneficial effects:

1. according to the invention, after the flour is put into a bin, the flour quality is blended in a technological manner when the flour is taken out of the bin, different types of mixing machines, batch scales and the like are added, different combinations of various flours are realized, accurate and flexible flour blending of different varieties and small batches of flour is met, and the long-term stability of the flour blending quality can be ensured.

2. Can meet the powder preparation requirements of different forms, and the powder preparation efficiency and the quality are stable and can reach the optimal balance. The accurate powder preparation method of the mixer can improve the accuracy rate of 70 percent from the traditional coarse powder preparation method to 96 percent. And because the accuracy of weighing, can avoid the powder blending that produces because of equipment is unusual to avoid appearing the unqualified condition of product.

3. After the flour mill receives a customer order, the flour is firstly mixed and put into a packaging bin, and the customer directly packages and loads the flour after arriving, even can be directly transported by a tank car. The waiting time of customers is reduced, the product is prevented from being stored in a warehouse, and the risks of food damage and pollution are reduced. Therefore, the production efficiency is not reduced by small-batch and multi-variety powder preparation, but different requirements of different customers are met.
