How to Identify good quality flour?

The quality standards and testing methods of wheat flour formulated by the country are difficult for many consumers to check the quality of wheat flour because of the need for inspection, laboratory technology and special testing instruments. But direct discrimination through sensory organs is a simple and easy-to-grasp testing method. This kind of sensory testing is to synthesize the quality of wheat flour by watching, smelling, kneading, twisting and biting.

Wheat grains

Watching:

Watching the pink bran of wheat flour can reflect its processing accuracy. Wheat flour bran plays a decisive role in the appearance of products. After milling and grinding, it scrapes the endosperm from the epidermis and it grinds the endosperm to the very fine parts. Generally speaking, the higher the accuracy of wheat flour processing, the lower the flour yield, the smaller the bran star containing broken bran, the whiter the flour. When the processing precision is higher, the flour size is more fine, and the flour color is white because of the light irradiation. The grain color and quality are different, the color of wheat flour is different too. Under the condition of low flour yield and low processing precision, the darker the grain color of wheat is, the darker the processed product is, and the color of wheat flour produced by white-skinned wheat is lower than that from soft-skinned wheat. It is because that in the flour processing process, white wheat bran is not easy to detect when it is mixed in the wheat flour, while red wheat bran is easy to detect when it is mixed and make the flour darker. Hard wheat endosperm is slightly yellow, soft wheat endosperm is milky white.

Wheat grain

Smell:

The wheat flour with good quality has normal odor and inherent sweet smell. It is very vulnerable to mildew and bacteria when we store it, and even oxidative deterioration. Mildewed wheat flour has a sour taste. When it is infected by pests (such as mites and beetles, it also produces sour taste. Mites can be identified by examining wheat flour or by the unique odor of mites). Feverish and mildewed wheat flour, through stored for a short time, has a low fatty acid value, but often has an unpleasant bitter taste (it is fatty acid decomposed, and then oxidizes acid to produce aldehydes and ketones). As a result, wheats with mildew and deterioration have peculiar odor, which seriously stimulates the sense of smell. If there are trace pesticides,it also cause peculiar odor, these can cause poisoning and should not be eaten.

Wheat flour

Kneading:

That is to say, to judge the moisture content of wheat flour by hand, to grasp a handful of flour with hand, to press it a little hard, to shake gently after loosening hands. If the flour disperses, the moisture content is within the scope of national standards, if not dispersed, the moisture content is not easy to be stored for a long time. Relevant experiments have proved that when the moisture content is 13.5%+0.5% and the temperature is over 30 ~C, it can only be stored for a short time.If it is processing after Autumn and 14% of the moisture content can be stored for half a year. When the moisture content reaches 15% and the temperature is above 20 ~C, it will quickly become hot and mildew. In addition, with the increase of water content, the actual weight of flour decreases, invisibly it harms the interests of consumers.

Twist:

That is to twist wheat flour, if it is uniform particle size and soft then it is of good quality, if too smooth or rough then the quality is poor.

In a word, according to the methods of watching, smelling, kneading and twisting, the quality of flour can be generally identified. For some adulterated fake flour, the final determination should be made by further qualitative and quantitative chemical analysis.

Top 10 Facts about Chinese New Year

How much do you know about the Chinese New Year?

Chinese New Year is a Chinese festival that celebrates the beginning of a new year on the traditional Chinese calendar.

Today let’s talk about the top 10 Facts about Chinese New Year

1 The festival date changes every year.

This is because it follows the lunar calendar, based on the movement of the moon. Usually, it falls on a day between mid-January and mid-February. In 2019, Chinese New Year falls on February 5

2 It is also called Spring Festival.

The festival usually falls after the solar term, Beginning of Spring (Li Chun), and is a festival in the spring, hence the name.

3 Chinese New Year starts a new animal’s zodiac year.

In China, each lunar cycle has 60 years and 12 years is regarded as a small cycle. Each of the 12 years is defined by an animal sign: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, and Pig. 2019 is the Year of the Pig.


4 The celebration lasts for 15 days till Lantern Festival.

The peak time of the entire celebration is on Chinese New Year's Eve and the first day of the lunar new year. The 15th day is called Lantern Festival, marking the end of the celebration.


People go out to watch the lantern party after eating Tangyuan.

5 One sixth of the world’s people celebrate it.

It is not only celebrated in Mainland China, but also observed in Hong Kong, Taiwan, Vietnam, Singapore and some other Asian countries as well as China towns around the world.

In recent years, the celebrations in New York, London, Vancouver, Sydney and other overseas cities have spread out of Chinatowns. Chinese New Year has become one of the world’s most celebrated festivals.


6 It is the longest public holiday and the whole country is on the move.

Most employees have 7-12 days off the work, and students have one month winter vacation. The 2019 Chinese New Year holiday is from February 4th to 10th.

No matter where they are, people try their best to return home for a family reunion, like westerners attempting to spend Christmas with their families. Meanwhile, some families travel together during the holiday. This makes the world’s largest annual migration, known as the Spring Festival Travel Rush. The total trips made by plane, train, bus and ship can reach nearly 3 billion.

7 Reunion dinner is a ritual.

The reunion dinner on Chinese New Year's Eve is a big feast to commemorate the past year. This is the most important time to be with families.

After the reunion dinner, families sit together to watch the CCTV New Year's Gala while chatting. As the most watched TV program, the gala collects various well-selected performances, targeting audiences of different generations.

8 Then comes the annual largest usage of fireworks on the planet.

Fireworks are an indispensable part of the celebration to liven up the air of Spring Festival. All families set off fireworks to celebrate the festival. The biggest firework show is on Lunar New Year's Eve.


9 The celebration decorations are mostly in red.

Houses are decorated with red Spring Festival couplets, red lanterns, and red paper cuttings; city streets are lit up by red lanterns; and numerous people are dressed in red. This is because red in Chinese culture is the symbol of happiness, wealth and prosperity, and can ward off evil spirits and bring good luck. These red decorations are to the festival what Christmas trees are to Christmas.

10 “Guo Nian Hao” is one of the most used greetings.

This is like the westerners saying “Merry Christmas” to each other on Christmas Day. It means “Happy New Year”.

Why is the celebration also called "Guo Nian"? "Nian”is the Chinese word for year. In folk culture, the Spring Festival celebration is also called “Guo Nian” (meaning “passing a year”). In a Chinese New Year story, “Nian” is a fierce and cruel monster which eats livestock and kids, but it is scared of red color and cracker sound. Therefore, people use red decorations and fireworks to drive away “Nian”.Hongdefa Machinery will off work for new year holiday according to the National Holiday Provisions.If you have any issue about corn/maize/wheat flour mill machine,please kindly tel/whatsapp +86 13722885205 or email us penny@hdfmill.com

What Shall We Pay Attention When Use the High Plan Sifter?

High plan sifter is the main sifting equipment of the flour milling machine factory. The quality of flour and the extraction rate of flour are directly related to the efficiency of the high plan sifter. Hongdefa factory use word top quality sifter. It has the characteristics of large screening capacity, high screening efficiency and no need frequent maintenance. Let's take this equipment as an example to talk about some problems that should be paid attention to when using of high plan sifter in practice.

High plan sifter

First, the following conditions need to open high plan sifter:

Sifter screen

1) The materials under the sifter are highly mixed and the classification effect is poor. Shows that the sifting efficiency is low, the main reason is paste sifting or different types flour mixed. If like this, should stop the wheat or maize mill production line for inspection. Use the nylon brush clean the screen surface to increase the effective sifting area. Replace or replenish the cleaning balls (blocks) and picking blocks in the sieve. Because the frequent cracking in the product, some are worn, and the broken cleaning block and the mash block flow along the pipe to the feeding cylinder of the roller mill.

2) When testing the color of flour, if you find that the flour contains excessive amounts of bran, also please stop the wheat or maize flour mill machine production line. The reason is that the sieve is broken. If the nylon crucible is hard damaged, it must be replaced; if the damage is not large, it can also be repaired with a small sieve of white glue.

3) In the patrol inspection, if there is no flow under the screen, tap the high plan sifter door and make a “squeaky” sound, indicating that shows the sifter is clogged. It is possible that the inner and outer passages of the screen are clogged and the material circulation is not smooth. If it is just happening, you can keep the flour mill machine production line working, just stop feeding, unblock the outlet, then make the sifter back to normal operation. If the blockage is serious, then shall stop the working for maintenance; it is also possible that there will be too much material in a short period of time, and there will be sifting. Stop of feeding, and the material can be reasonably diverted according to the design flow and practical experience.

Second, when open and installing the parallel sieve, shall be careful to ensure the efficiency of the flat sieve.

Top quality screen

1. When installing the sieve, it should be placed in the order of the numbers and arranged neatly. The flour in the sifter should be cleaned to prevent the screen from being placed unevenly and gaps appearing. Please take attention Can't be careless, placed upside down or not mixed by number. Especially when open two bin at the same time, do not confuse them with the next compartment.

2. When checking the sieve, the screen surface should be tight and should not be slacked. Otherwise, it will affect the normal operation of the cleaning block (rubber ball), and the material will accumulate in the depression to reduce the effective sifting area.

3.The flannel around the screen frame should be kept intact. If it is missing, it should be replenished in time, otherwise there will be flour leakage. When installing the sifter, the sealing strip cannot be knocked out. In operation, the front part of the sieve is placed in the sieve box, and then the rear section is lowered.

Spare parts of high plan sifter

4. After the sifter is placed, it will be compacted at the end. In the vertical direction, the screw pressing mechanism of the top of the warehouse is used to adjust the screen to each other by adjusting the left and right screw mosquitoes. During operation, the left and right thread should be adjusted in turn to prevent the one side from loosening, causing the displacement of the screen, causing the powder to be powdered, and the screen to be pressed in the horizontal direction. Because of the horizontal direction, the screw on the door can be adjusted. In order to make the horizontal pressing force uniform, the correct adjustment sequence should be tightened along the diagonal.

5. When restarting, the flat screen should be idling for a few minutes to make the material empty, so as to prevent too much material in a short time, resulting in blockage.

Third, regular inspections to ensure normal operation

Hongdefa factory high plan sifter

1 If there is abnormal sound or impact sound in the high plan sifter during the inspection, it is very likely that the sieve grid is not pressed, and should be stopped immediately for maintenance.

2 In summer, the relative humidity in the air is large, and the upper and lower cloth sleeves of the high plan sifter are easily to fall, resulting in the outflow of the materials. In particular, fine flour, such as the wheat heart re-sifting (DIV3), bran sifting (DF) and so on. It is necessary to remove the flour on the ground in time, keep the workshop sanitary, and connect the cloth sleeve.

Why Can Earn Big Profits By Maize Milling Factory?

Before we knowing the secret of the maize flour factory to get the big profit, let us know well the maize milling machines design and flow chart first.

As we know the maize mill business is a big market in many Africa countries,like maize mill in Zambia,maize mill for Kenya, maize posho mill in Uganda,maize flour mill in Tanzania etc. In Kenya, Local people’s staple food is Unga,Ugali,fufu etc.The main food is Maize meal or maize flour ,in Nairobi,the market needs sifted maize meal and different grades, and in Mombasa,it’s more strict, people like the pure white maize meal, not so soft.

Technical flow of maize mill machines

The main point in a maize milling machines in Kenya, is the maize degerminator. The super white maize meal extraction in Kenya is from 73% -92% depending on different demands from the market and different customers, This will request to take the germ and the maize bran skin out of the maize meal by the

Degerminator in the maize mill in Kenya market. We have designed the special degerminator, combined Japan and America technology, which can remove the germ and bran from the maize grains.


It is the heart of the maize milling business, if this machine not good technology, no matter how good your other machines, your machine still could not get high quality maize meal for Kenya people. That is the key point in a maize mill processing line.

degerminator in maize mill machine

So for our degerminator we use Japan and America degerminating system and separate system, with the American technology for the degerminating system and South Africa maize experience, which can scrub the maize germ and maize skin out of it cavity, with the minimum deduction of the maize meal, will get high maize meal extraction with good quality.

For the milling section use China advanced brand automatic roller mill, and China advanced plan sifter. For this whole plant just one characteristic “advanced” and “customized”.

1) The partitioned paneling and swing-out feed module guarantee ideal

2) access to the feeding and grinding rolls. This makes residue-free

3) cleaning possible.

4) a pulse generator automatically adjust the feed material at the entrance door

5) bearing SKF

6) temperature monitor (option)

For the maize mill business trend, like in 30 years ago in China, there is many small factories for wheat flour mill, almost one county have 2 or 3 flour mill factories,the competition is very strong.

Then most of factories leaders begin to think how can I earn money?

I have to enlarge my capacity, everyday I can processing extra 50T or 100T flour,then I will low down the sales price of my flour, but I can sale more, then other people will not have the ability to compare with me. When he have this planing,he begin to collect the money, find the finance, beginning to enlarge the capacity of the wheat flour mill, before he sale 1USD per kilo, now he low down the price to 0.8usd per kilo, all the housewife buy his flour, quality is fixed good, price is low, the other small factory have low market low client, after sometime, the other small wheat flour mill factory closed. Then the big wheat flour mill factory become bigger and bigger, that is why in China now the wheat flour market are controlled by few big factories. If you want to see the small wheat flour mill machine running, almost impossible.


Maize meal and maize flour are waiting for selling.

Customer is very happy about selling maize meal.

The trend is similar in Kenya. There are some small maize millers , local made machines in Kenya,but the capacity is small and the production is small. If someone in Kenya is able to set up a big maize mill factory

Like 50t/24h,100t./24h,150t/24h,200t/24h , then in the future he can follow the experience in China wheat mill factory,daily capacity is much more than the small maize millers, and he can sale the maize meal at a very competitive price! The small maize millers can sell the maize meal at 1USD per kilo,but He can sell the maize meal at 0.8USD per kilo. The wholesaler come to buy the maize meal from this big maize millers,the housewife come to buy his maize meal from the big maize millers, he will be the leader of the market! Finally he win in the market!

Importance of Water Regulation in Wheat Raw Grain

Today share with you the importance of water regulation in wheat.

The purpose of wheat water regulation is to increase the toughness of the cortex and keep the bran intact during processing. The embryo softens and grinds to flour. In the national standard, the moisture content of common flour is less than or equal to 14%. The moisture content of high gluten powder is less than 14.5%. Different customers have different requirements for water. We should have targeted processing water.


The amount of water added to each food processing workshop and noodles is basically constant, but the external environment changes greatly. In the process of food processing under different temperature conditions. The dough softening speed is different. For example, the water content of flour should be lower under the condition of high temperature and water temperature. It hardens the dough and slows down the softening process. So in late spring, early summer and autumn, the water-saving points should be lower, and in cold weather, the water-saving points should be higher.


There was a great deviation in the water-eating ability of different wheat varieties. This is due to the quality of gluten. The absorptive capacity of gluten is at least 1:1.6. The highest: 1:2.7. The wheat gluten with low soft bulk density and unsaturated grain absorbed less water and was easy to soften. If wheat with high hard bulk density and full grains has strong water absorption ability. The dough is quite stiff. New wheat gluten has not yet been fully formed. That is to say, the ripening period is not enough. He also tends to soften.


That is to say, the water content of flour is higher when processing wheat with high hard bulk density and full grain. The moisture content of new wheat flour processed with soft, low bulk density and unsaturated grains is lower. In addition, the deviation of water absorption ability of each part of wheat grain is relatively large. The central part of wheat has strong water absorption ability, and the more dependent it is on the periphery, the worse it is. In the process, the front core grinding flour has strong water absorption ability.

That is to say, the moisture content of wheat flour with different qualities should be different. The same wheat has different identities under different climatic conditions. Flour in different technological positions has different water absorption capacity, which can be chosen according to the requirements of flour quality. Only by knowing how much water is added to wheat and in different seasons can you ensure the stability of your flour.

Our Hongdefa have more than ten engineers with more than 30 years' experience for flour milling machine. And have many successful flour mill project in all over the world.
