The wheat cleaning process is a vital part of wheat flour mill process. It refers to a series of consecutive process steps starting with the cleaning of impurities, wheat moisture regulation and mixing, and continuing until it is ready to enter the wheat flour milling stage.
This ensures that the wheat seeds meet the expected quality standards before it enters the wheat flour production stage, thus guaranteeing the quality and productivity of the final wheat flour.
In this article, we will introduce the steps of the wheat seed cleaning process before wheat milling and the wheat cleaning machines equipped in the process. As the saying goes, "A good cleanup is half the job." The importance of the wheat cleaning process for milling cannot be ignored, and if you are planning to start a profitable wheat flour mill plant, this will help you make a wise investment decision.

The work carried out in the wheat cleaning plants consists of removing impurities from the wheat, which can be achieved using a variety of wheat seed cleaner and techniques, such as sieves, magnetic separators, and so on.
In addition, adjusting the moisture of the wheat is one of the important steps in the cleaning process, and proper moisture adjustment ensures optimal processing of the wheat during flour milling process.
In well-equipped wheat flour mill plants, the cleaning process also involves wheat metering and wastes treatment.

In the actual production of wheat processing plants, the wheat cleaning process needs to be designed in accordance with certain principles of the combination of rational layout of the various functions of the wheat cleaning equipment, in order to optimize the cleaning effect. |

Wheat cleaning methods are divided into two types: dry cleaning and wet cleaning. The difference is whether or not to use a wheat washing machine.
Only a reasonable design of the wheat cleaning process, can use the least wheat seed cleaning equipment, to achieve the best cleaning effect. At the same time, it can also reduce the wear and tear of the working parts, prolong the service life of the wheat seed cleaning machines, and save the production management costs. Here is an example demonstration of the wheat grain cleaning process.

Wheat Cleaning Process and Equipment Layout Design Drawings
Wheat Cleaning Process Arrangement:
Gross wheat → Gross wheat bin → Automatic scale → Head sieve → Head wheat scouring → De-stoning wheat washing machine → Dampener → Conditioning bin → The second wheat scouring → The second sieve → Magnetic separator → Clean wheat bin → into the grinding mill
In the selection of cleaning equipment and combination of processes, must be based on the net wheat quality standards, and combined with the impurity of the wheat seed, plant production capacity, the type of finished product, the quality of wheat and moisture adjustment methods and other factors for comprehensive consideration.
Wheat with a large amount of impurities, the design of the cleaning process should be more perfect; wheat with a small amount of impurities, cleaning process can be appropriately simplified.
How to optimize the wheat cleaning process based on impurities？
| Wheat Impurity Status | How to Optimize |
|---|---|
| More Buckwheat, Grass Seeds, Barley, and Oats | Strengthen Wheat Selecting Process |
| More Sand, Mud, Coal Residue | Intensify Wheat De-stoning Process |
| More Diseased, Pest-Infested, or Shriveled Wheat | Increase Wheat Scouring Process |
| More Dust | Enhance Suction and Dust Removal Process |
| Low Wheat Moisture | Consider Secondary dampening Addition if Necessary |
The cleaning process or suction dust removal system of small wheat flour mill plants can be simplified appropriately, and combined cleaning equipment is often used. (Related Post: How to Start Small Flour Mill Business>>)
Large-scale wheat flour production plants can use more self-circulating air suction system and have wheat wastes workshops or process.
When using wheat cleaning equipment with good quality and high efficiency, the number of cleaning passes in the process can be appropriately reduced, or a larger equipment flow rate can be selected to reduce the number of equipment.
When the equipment efficiency is poor, the cleaning process should be strengthened or a lower flow value should be adopted.
