How To Improve The Flour Processing Quality Of Wheat Milling Machine?

With the rapid development of the global economy and the continuous improvement of people's living standards, consumers have put forward higher requirements for the quality, nutrition and diversification of traditional wheat flour products, and the wheat flour processing industry has been rapidly developed and expanded. The technological progress of wheat flour mill processing technology and equipment has played an important role in improving the modernization level of the flour industry.

Reasons for blackening of flour produced by wheat milling machinery

In fact, wheat flour is not the whiter the better nutrition, people do not have to deliberately pursue the high precision of flour in life.  However, when consumers buy flour, color has always been a criterion for judging the quality when buying. Therefore, the staff need to pay attention to the color change of the processed flour. If the color is not normal, the manufacturer should pay attention to timely improvement, otherwise it will affect the sales of the product.The blackening of the flour produced by the wheat milling machinery is a relatively common phenomenon, but how exactly is this caused?

The Influence Of Operation Method And Raw Material Quality

Generally, the normal color of the flour processed by the wheat milling machine is white, and sometimes it may appear black and blue. There are many reasons for this abnormal color, such as low output, thin flow layer, excessive pressure on the grinding roller, dense bottom of the flour processing machine, and excessive powder content in the mil machine.

Flour machinery manufacturers can summarize the reasons and solutions for the abnormal color of wheat flour based on the performance of the product and various operations at that time.As shown in the table below:

The Reasons And Solutions For The Abnormal Color Of Wheat Flour

Reasons for the abnormal color of flour Solutions
Low output, thin flow layer Increase production and flow
Roller pressure is too high Adjust the roller pressure
Wheat milling machine has a dense sieve bottom Coarse powder sieve bottom

The Influence Of Gluten Content In Wheat Flour Milling Machinery

Wheat Flour Production and Manufacturing

The color of flour is not only related to the operation method and the quality of the raw grain, but also affected by the gluten content in the wheat milling equipment. For example, high-gluten flour is darker in color, more lively and smooth, and it is not easy to clump when grasped; medium-gluten flour is milky white, and the body is semi-loose, between high-gluten flour and low-gluten flour; low-gluten flour is white, It is easy to clump with your hands. This color difference is also related to the gluten content in the flour.

Master The Correct Technical Points To Improve The Quality Of Flour Processing

The quality of wheat flour will directly affect its taste, preservation of nutrients and price. Therefore, when processing wheat, technology is the top priority, so today ABC machinery will introduce how to master the correct technical points to improve the quality of flour processing.

  • First, peel and clean up.

Put the processed wheat into the hulling cleaning machine for cleaning, and pass the mechanical vibrating screen to remove the large and light impurities to reduce the pressure on the equipment.By threshing wheat twice and removing impurities twice, the soil on the surface of wheat can be knocked off and a lot of impurities can be removed.  It is best to use a flat rotary sieve to screen the grains after each barley, and extend the route of the sieve to improve the efficiency of screening, and at the same time strengthen the suction and use the wind to blow away light impurities.

  • Secondly, moisture adjustment.

Before the wheat is milled, watering and moisturizing the wheat with excellent texture can effectively adjust the physical, biochemical, and flour milling characteristics of the wheat. It is one of the key links to improve the flour color and ensure the quality of the flour. Therefore, in the manufacturing process, it is first necessary to ensure that the cortex and endosperm are completely separated to reduce the content of bran in the flour.

  • Finally, the operation of the wheat milling machine.

Using the same wheat in the same complete wheat flour production line, whether the flour machine is operated properly or not, the powder extraction rate differs by 2%, and the flour ash differs by 0.2%. Therefore, in the operation of the wheat mill machine, the first three skin mills are particularly important. The first three skin mills should loosen the rolling distance and implement light milling to avoid the bran from being ground. Otherwise, the bran will be mixed into the flour and difficult to sift out.


The above is the method to improve the flour quality summarized by ABC Machinery.Only by using wheat milling machinery correctly can manufacturers improve the quality of flour processing, increase productivity, and create greater profits.
