Some Simple Operations of Roller Mill in Wheat Flour Mill Plant

The same wheat flour mill line, the same raw grain, and different operating skills will produce significantly different flour milling effects. As far as the grinding effect and equipment operation in wheat flour mill plant are concerned, good technology and equipment are the prerequisite, and the correct operation skills are the guarantee. Only in production practice, in strict accordance with the requirements of process design, comprehensive consideration and careful operation, can the overall effect of the process be brought into play.

 

Hongdefa 60t/24h wheat flour mill plant

 

1. The grinding effect of the wheat roller mill

The main equipment in the grinding process is the roller mill machine. In the process design, the grinding effect of the roller mill machine is measured by the stripping rate and the powder extraction rate. Its size is measured by an experimental sieve, but in the process of milling The size of the material is tested by observing the crushing condition of the material after grinding, and the degree of grinding is judged by analysis. In order to find out the problems in process, equipment and operation in time.

 

 

2 Operation skills of the roller mill

Determine the best grinding flow rate

Each powder path has a certain flow range. When the flow is too large, the uniformity of material crushing will decrease. If the flow is too small, it is easy to make the feeding state abnormal and the equipment work unstable. In the process of wheat flour mill plant, the best feed rate should be determined according to the condition of the raw grain. At the same time, it is necessary to combine the ambient temperature and humidity to detect the maximum inlet flow rate that can be reached at the time, and gradually adjust the flow to ensure that the materials are distributed to each system in the proportion required by the process design, so as to determine the best inlet flow rate. .

After the optimal feed rate is determined, if the moisture, softness and hardness of the raw grain do not change much, it is not advisable to frequently adjust the feed rate to avoid disrupting the process balance and causing blockage and material drop. If the water content is uneven, the inlet flow rate should be adjusted appropriately. Generally, when the moisture deviates by 1% from the best water entering the roller mill, the flow of entering the roller mill should be reversely adjusted by about 10%. In addition, changes in seasons and climate also have a significant impact on the optimal grinding flow rate. When high temperature, high humidity, and low air pressure, the material is wet and sticky, the grinding flow rate should be appropriately reduced.

 

3.Final summary

The grinding effect of the roller mill is affected by many factors such as the nature of the incoming material, the flow rate, the feeding effect, the operating parameters of the mill, the surface parameters and processing quality of the grinding roller, the assembly quality and cleaning effect of the grinding roller, and the operation index. To stabilize the grinding effect, ensure that the quality, flow, and particle size of the incoming materials are uniform.  The working parameters of the mill are reasonable and accurate, and the operation is safe and reliable. The surface parameters of the roller mill should be adjusted appropriately according to the material properties, flow, grinding requirements, ambient temperature, humidity, etc. To improve equipment operating skills, we must strictly follow the regulations and indicators to perform fine operations. The skin mill system must achieve the target stripping. While strictly controlling the stripping rate and powder extraction rate of each pass, it also controls the total stripping rate, powder extraction rate and the integrity of the bran. The heart mill system must achieve the target powder extraction, while ensuring that the bran flakes contained are not excessively broken, it also extracts the wheat flour of the corresponding quality and particle size in a targeted manner. Practice has proved that the quality of the obtained wheat flour is completely different by selectively grinding and extracting flour and non-selectively pulverizing and extracting flour. As far as wheat flour mill plant and equipment operation are concerned, good craftsmanship and equipment are the prerequisite, and correct operation skills are the guarantee. Only in production practice, in strict accordance with the requirements of process design, comprehensive consideration, careful operation, more observation, more analysis, and more thinking. Only in this way can the best process effect be achieved, and the various economic and technical indicators can be guaranteed and improved, and the best powdering effect of high quality, high yield and high efficiency can be achieved.

Introduction of maize milling machine processing technology

                  Introduction of maize milling machine processing technology 

Everyone is familiar with maize flour, but how much do you know about the processing technology of maize milling machine?

Complete maize milling machine includes maize cleaning, milling, packing and control system.


Cleaning Machine:

Before the maize is processed, it must first be cleaned, and the raw material is maize that is free of mold, insects, and odor. This requires the use of gravity classification stoner.

The destoner is applied for efficient separation of stones and pebbles, glass, and other high-density matter from the stream of grain. It can remove all the impurity, such as steel, stones, ropes and so on.

 

Then the cleaned maize enter the damper. The damper can add a small amount of water to moisten the raw maize. In the Moisture bin,the maize can sleeping,and the maize skin can absorb moisture to better remove the germ and bran.

 

High Efficiency Grain Damping of ZSQ Series is an important piece of equipment to control the water content of the maize during maize cleaning in flour mills. Stainless steel. Bi-directional screw, Prevent free water, an intensive Intermixing.

 

Degerminator is designed to ‘scrub’ the bran skin from the maize kernel and to dislodge the germ from its cavity, with the minimum reduction in size of the broken fragments.


 

It can remove the maize bran and germ with the most efficiently. Then you can get the super white maize meal with low fat and without any black point.

 

Milling Machine:

Use maize roller mill to grind the raw maize to maize flour, then pass through the plansifter to screen out different particle sizes of maize flour.

 

1)The partitioned paneling and swing-out feed module guarantee ideal access to the feeding and grinding rolls. This makes residue-free cleaning possible.

2) a pulse generator automatically adjusts the feed material at the entrance door

3) bearing SKF

4)Sensor: Omron


 

1) Material: High-strength alloy steel

 2)up and down sifter circles with steel plate overall by bending

 3)Transmission system using spring force component institutions

 4)Sieve frames of wood coated with synthetic resin, without backfire

 5)All the inside walls, as well as the doors, are provided with high-grade insulation

 6)Vertical and horizontal clamping system.

Control System:

Automatically display raw maize, clean maize, maize flour, pollard, bran instant flowing quantity.

Automatically display raw maize, clean maize, maize flour, pollard, bran instant flowing percentage.

With working history checking system. With fault alarm system. With printer.

 

In the past two moths, we have installed many sets of maize milling machines in Africa.

Popularization of Hongdefa wheat flour processing technology

 Popularization of Hongdefa wheat flour processing technology

Wheat flour processing technology is to grind wheat into flour to meet various needs. A set of good processing technology can improve the efficiency of wheat flour processing machine, and meet the production conditions of energy-saving, environmental protection, high-quality and high-efficiency to the maximum extent, and enable customers to have a long-term, stable and sustainable profit-processing plant.

Wheat Cleaning process

There is a saying in the flour industry that "good cleaning is half the work". In order to make high quality wheat flour, we should start from the raw wheat, the first is the pretreatment of wheat processing, that is, the so-called primary cleaning and one cleaning and two cleaning. The purpose of wheat processing pretreatment is to remove impurities, ensure the normal operation of equipment, and ensure the quality of finished products. Due to the selection, cultivation, harvesting, threshing, drying, transportation and storage of wheat, some impurities are inevitably mixed in. And the process of cleaning up impurities is the wheat cleaning process.

wheat cleaning machine

 

In the actual production of wheat flour processing plant, it is impossible to use a cleaning machine to remove all impurities in wheat, but all kinds of machine should be reasonably combined together for cleaning. Wheat cleaning process is referred to as wheat road. It is a production process in which the cleaning processes are combined and the wheat is continuously treated according to the quality requirements of the milled wheat. A perfect and reasonable wheat cleaning process is not only an important link to ensure product quality and improve product purity, but also an important key to increase yield and flour yield, reduce power consumption and stabilize flour milling operation.

 

Water regulation

 

The next step is to adjust the moisture content of wheat, which is what we usually call moisturized wheat. By adjusting the water to increase the free water in the middle of the wheat, the toughness of the wheat cortex is enhanced, and the granular starch in the endosperm becomes loose. This change is to promote grinding and reduce energy consumption. The endosperm is easy to crack, and the cortex is not easy to crack, which makes it difficult for the wheat cortex to be mixed with flour during grinding and screening. The results show that the wheat flour after water transfer has better color, quality and higher flour yield.

Before entering the roller mill, we need to perform final processing on the wheat, such as magnetic separation, pre-pressing, screening, etc., to ensure that the wheat is clean before entering the roller mill and to reduce the working pressure of the front bark mill. 

Wheat Milling System 

After the pre-processing of wheat is finished, we will send the wheat to the milling system for milling. The purpose of our flour milling is to mechanically process the clean wheat after cleaning and moisture adjustment into wheat flour with different needs, while separating the by-products. The purpose of grinding is to use mechanical force to peel the wheat grains, then scrape the endosperm on the bran flakes, and then grind the endosperm into a certain fineness of wheat flour. The main machine is a roller mill.

 

wheat mill

In the wheat flour milling system, sifting is also an essential item. The purpose of sifting is to classify the ground or impacted materials according to the size of the particles, and to filter out the wheat flour. The main machine is plansifter, bran beating machine and bran brushing machine.

 

 

Fine processing of finished products

Finally, there is the post-processing of flour. This process is the final stage of wheat processing, which includes the collection of flour, flour blending, weighing and the addition of trace elements. Flour collection is the collection, combination and inspection of the flour sifted out by each flat sieve during the flour milling process. The powder blending can make the ground flour meet the needs of various noodle products, and at the same time make the product quality stable.

wheat flour auto packing machine

 

In the process of milling wheat, we must follow the milling process of "light grinding and fine grinding, sequential push, homogenous merging, and continuous stability". 

We, Hongdefa Machinery has high quality wheat flour milling machine from 10t/24h to 1500t/24h with European Standards.
