How to adjust the powder cleaning machine during the operation of the flour machine

We know that in the complete set of flour machine, the powder clearing machine selects and classifies the materials through the screen and airflow, and achieves the purpose of “grading and clearing at the same level”. At the same time, we should balance the material balance of each system and move towards flexibility. Due to the special role of the powder cleaner in the flour mill equipment, it is decided that the adjustment of the powder cleaner can improve the quality of the processed wheat flour. In the operation of the flour machine, how should the adjustment of the powder cleaning machine be done according to the situation? Today, simply tell everyone about this issue.

First, the adjustment of the material direction of the powder cleaner.

As we all know, under the influence of factors such as changes in wheat varieties and water fluctuations, the flow rate of each system is prone to change. At this time, proper adjustment of the direction of the material of the powder clearing machine can balance the production of various materials and stabilize production, and improve the effect of wheat pink color. very obvious. Take the 3P material entering the flour machine as an example. The sieve can be imported into 1Mf, 2Mf, 2Mc, 3M. Which system is specifically used for grinding, and it should be flexibly distributed according to the condition of the original grain and the moisture of the milled wheat. The direction of the material, with a reasonable screen.

Second, regarding the adjustment of the material flow of the powder cleaner.

Practice has proved that the flow rate of the material entering the flour mill cleaning machine should be appropriate, the flow rate is stable, and the thickness of the material layer is uniform. If the flow rate into the flour mill is too large, the air is difficult to pass through the material layer uniformly, and the automatic classification of the material is poor. To a large extent, the powder clearing machine becomes a conveyor; the flow rate is too low, and the bran is easy to pass through the sieve. The pores are mixed into the pure powder. If the thickness of the layer is not uniform, the airflow passing through the screen surface of the grinding machine will inevitably be uneven, which will inevitably destroy the automatic classification of the material. The impure material will contact and pass through the surface of the grinding machine The effect is weakened, which affects the graded purification of materials. The operation of changing the flour mill and the arrangement of the high-screen sieve can adjust the flow rate of the material entering the powder cleaner. In order to stabilize the flow rate into the powder cleaning machine, in the operation of the grinding machine, when the moisture of the raw grain and the milled wheat does not change, the rolling distance of the mill generally does not change.

Third, adjust the air volume of the powder cleaner reasonably.

In the actual operation of the grinding machine, we should select the appropriate air volume according to the thickness and flow rate of the material entering the powder cleaning machine. For example, the same flow of coarse slag and other coarse materials require a large amount of air, but when the suction volume is too large, it will destroy the stratification of the flour machine screen material and affect the grading and purification. In addition, wind speed is also an important factor affecting the graded purification of materials. If the wind speed is too high, some of the good materials will be taken away by the airflow; if the wind speed is too low, the material will not easily pass through the screen surface and become the sieve material, which will not achieve the purpose of fractional purification. In order to ensure the purity of the flour machine under the sieve, when adjusting the powder cleaner, the air pressure in each suction section must be uniform, based on the movement of the material on the sieve surface. If the material is uniformly boiling on the sieve surface of the grinding machine, and the sieve head is gradually pushed toward the sieve tail, the bran is sucked out, that is, the optimum state of the powder is reached.

The above is how to adjust the powder cleaning machine according to the situation in the operation of the flour machine complete equipment to ensure the pink and quality problems of wheat flour.
