Optimizing Maize Milling Process: Techniques and Equipment

Maize, or corn, is one of the most widely planted grains in the world. It is the main grain crop in Mexico, Brazil, Argentina, etc. While other countries like America, China, and most African countries, like South Africa, Nigeria, EthiopiaTanzania, also harvest large quantity of corn/maize every year.

Maize/Corn Flour Milling Process and Purchasing Skills

The complete maize flour milling process involves various maize milling machinery, mainly for maize cleaning and flour milling. Scientific and reasonable corn flour processing processes should be automated, which can not only reduce labor cost and energy consumption, but also ensure the quality of the final maize products.(Read more: Wheat Flour Production Process >>)

Complete Maize Flour Milling Process

• Impurities Removal Process

Maize kernels are fed from the material inlet and the flow rate is controlled by a baffle. When the maize kernels are transported by the bucket elevator into De-stoner, they first go through fine sieve, the sand or other impurities smaller than maize will be screened out and discharged from the taphole. After fine sieving, maize kernels enter Coarse Screen to screen out impurities that are bigger than corn, for example, corn cob particles; while these impurities are also discharged from taphole. At the same time, above the sieve, it is connected with a fan. The function of Fan 1 is to suck those light impurities still mixed in maize kernels; such impurities will be eliminated by the function of centrifugal sedimentation. (Relate equipment: Grain Cleaning Equipment >>)

After cleaning, maize kernels go out the outlet and delivered into screw conveyor. Maize kernels flow in the screw conveyor and dust or similar small particle impurities are further screened out. Then, maize is delivered into Dampener. In the dampener, maize kernels and water are fully stirred and mixed. Those maize kernels that meet dampening requirements will be delivered again by the elevator into storage barrel for temporary storage, whose purpose is to make sure the feeding flow in next step is even.

• Preliminary Breaking & Embryo Selection

On the outlet of storage barrel, there is a baffle to adjust discharging flow. When maize kernels get out, they will enter slag mill for preliminary breaking, so that some maize skin is separated from embryo. After that, broken maize is delivered by the elevator into Embryo Selection Machine. Inside it, maize skin and embryo are separated and expelled from different outlets. At the same time, on the top of embryo selection machine, there is connected Fan 2. Under the function of fan, some light impurities are sucked out, while the embryos discharged from the outlet of selection machine are delivered by Suction Fan 3 into Maize Flour Mill 1. Those maize skins discharged from the selection machine and some broken embryos will be delivered into Maize Flour Mill 2. (Read more: Maize Flour Milling Machine >>)

• Finished Maize Flour Classification

The maize flour milled by maize flour mill machine are sucked by Suction Fan 3 and delivered into Double Bin Sieve 1 for sieving, and the maize flour that meet standards will be ejected by Suction Fan 4 for weighing and packaging. While the maize flour that does not meet crushing standard will be screened out from Double Bin Sieve and then delivered by Suction Fan 3 into Flour Mill 3 for further grinding. The discharged material is delivered by Suction Fan 3 into Double Bin Sieve 2 for sieving: the corn flour that meets standard will be ejected by Fan 4; those substandard will be delivered by Fan 3 into Maize Flour Mill 4. After milling, maize flour is again delivered into Double Bin Sieve 2 for screening. (Read more: Cost of Setting up a Maize Mill in Uganda >>)

Maize Flour

Over such cycling of maize milling process, maize flours can meet different classification standards. Depending on maize flour content and particle size maize flour is classified into 4 grades:
► Grade 1 and Grade 2 are mainly maize skin and small proportion of maize flour, and are generally used for animal feed;
► Grade 3 and Grade 4 are fine maize flour that are used in food related industry for human consumptions;

The right way to purchase maize flour processing machine

Many investors know that the maize flour processing machine produced by different manufacturers、different manufacturing methods and different materials are different, and the corn flour produced will also be different. Therefore, investors need to choose the right method when choosing corn flour processing machinery in order to purchase the right equipment.

Choosing Best Maize Flour Milling Machine

First of all, for corn flour processing equipment with better quality, its bearings and gear boxes should be far away from the valve body to prevent the influence of high temperature and impurities, and the front and rear covers must have a better sealing effect to avoid dust leakage. It has a very good overload function of the airlock, which is more suitable for more starting and forward rotation, and the processing efficiency of the whole machine will be higher.

Secondly, the corn flour processing machine processes the raw materials by adopting the principle of planetary rotation. The design input and output are all on the same axis and connected with the motor. Its teeth are made of cast iron and bearing steel, which is compact and runs. It is more stable, has the advantages of low noise, fewer problems, and long life. When comparing this kind of machine, personnel can consider these aspects to do component analysis to ensure the quality of the machine.

It can be seen from the above that when purchasing the maize flour processing machine you need to pay attention to many aspects. Therefore, knowing more industry information and product information can effectively help you screen, which is the right way.

The Development Status of Maize in its Main Producing Countries

The history of eating corn is very long. People started to eat corn flour before eating corn. But the previous technology level was relatively low, and the variety and taste were not good. However, with the emergence of maize flour mill processing equipment, the variety of corn products continues to increase, and the taste gradually meets people's requirements and market expectations, which makes the maize flour processing industry seize the market's rising space and attract people's attention. As the third largest polar food crop in the world, corn has extensive nutritional and health value and development potential. How to use the technology introduced at home and abroad to implement the intensive processing technology of maize flour processing equipment so that maize food can enter various countries and regions into a larger market is an urgent problem for maize flour production businesses.

Maize Production Countries

The combination of maize flour milling machine with agriculture provides a good opportunity for industrial development. In daily life, raw grains can be made into flour products through maize flour milling equipment, and then various foods can be made for people to use, which brings great convenience to people. Therefore, it has brought a good development in the maize flour processing industry and has been greatly affected. The processing manufacturers are welcome. Go to ABC Machinery to directly purchase a complete set of equipment, including peeling, grits and other auxiliary equipment, which prevents the equipment time, as well as accessories and wear parts.
