Wheat is an essential part of our diet without which no Indian’s food is complete! But do you know where it comes from?

Do you like cakes? You must love them, but have you ever wondered about the story behind the flour that is used to create such a heavenly sweet thing? Well, wheat is what converts into flour and then into your cake.

Wheat is an essential part of our diet without which no Indian’s food is complete! But do you know where it comes from? The thing is when grain is ground in a flour mill machine, it converts into wheat. The wheat grinding machines are basically the connector that makes the whole process of this transformation complete.

So, today, we are going to know what actually happens to a grain when it is milled by a flour mill machine. Take a look:

There are hundreds of varieties of wheat that are milled in the mill plants. During the milling process, the various parts of the wheat grain are used to create different flour types.

The days of milling process that involved grinding the grains of wheat between the two large wheels are long gone. Now, the modern wheat grinding machines do the whole job. It consists of steel rollers that sit a bit apart from each other.

The wheat is first cleaned and conditioned which is then blended. Here, different kinds of wheat are combined to produce a mix that can, later on, create a fine quality of flour.

During the milling process, the wheat grain gets fragmented into various parts that are separated when it is passed through the arrangement of sieves that is quite a bit complex. The wheat is not crushed but rather split open to separate its two skins.

The white endosperm particles of wheat are known as semolina that is further channeled into deduction rolls for final milling where it converts into white flour. The wholemeal flour has all the parts of grain while brown flour doesn’t include any wheat germ and has also less amount of bran.

During this modern milling process, the bran particles are removed from the endosperm. The endosperm is grounded into the flour while ground stock gets sifted. The final part of the whole milling process is sifting after which the flour is automatically packed into the bags that are then sent to the shops for the selling. The leftover part that is bran is sometimes used as an animal feeder or in breakfast cereals.

At these milling plants, proper inspections and tests are made for the healthy production of flour. However, the heating processes destroy any pathogens present in the flour and reduce the risk of foodborne illness.

The nutritional value of the flour is not at all determined by the method of milling but if it is wholemeal, brown or white.

Raw Paddy Drying Solutions by Nextech

By “drying” is meant the phase of the post-harvest system during which the product is rapidly dehydrated to a so-called “backup” moisture. This desiccation is intended to sufficiently reduce the moisture content of the grain to ensure favorable conditions for storage or subsequent processing of the product.

By “drying” is meant the phase of the post-harvest system during which the product is rapidly dehydrated to a so-called “backup” moisture. This desiccation is intended to sufficiently reduce the moisture content of the grain to ensure favorable conditions for storage or subsequent processing of the product.

It is possible to obtain the drying of the products by circulating more or less hot air in a mass of grains. In its movement, the air gives heat to the grains, absorbing moisture from the most superficial layers.

The water present in the surface layers of the grains evaporates much more efficiently and more rapidly than that of the inner layers.

It is therefore much more difficult to lower the water content of a product from 25% to 15% than from 35% to 25%. It would be wrong to think that this difficulty can be overcome by carrying out a rapid drying at a high temperature. Indeed, such drying conditions generate internal tensions, producing small cracks that can lead to breakage of grains during subsequent treatments.

For the drying of grains, the methods employed are, in essence, two in number:
– Natural drying
– Artificial drying

Both have advantages and disadvantages, and there is no ideal way to meet all needs.

Natural Drying

The method of natural paddy dryer, to which the techniques illustrated in the section on pre-drying operations also relate, consists essentially in exposing the beaten products to the air (in the sun or the shade). To obtain the desired moisture content, the grains are spread in thin layers over a drying area, where they are exposed to air (in the sun or the shade) for a maximum of 10-15 days. To promote uniform drying, the seeds should frequently be stirred, especially if they are exposed to direct sunlight. In addition, for the drying to be sufficient, the relative humidity of the ambient air must not exceed 70%.

Artificial Drying

The introduction of high-yielding crop varieties and the gradual mechanization of agriculture now make it possible to harvest large quantities of grain in a short period. In the tropical and subtropical humid zones, given the unfavorable weather conditions at the time of harvest, it is often difficult to safeguard the quality of the products.

To meet the need to increase agricultural production, it is, therefore, necessary to dry the products in a relatively short time, and whatever the ambient conditions. Thus, paddy dryer plant must be used. This method consists essentially in subjecting the grains to a forced ventilation of more or less heated air. It requires the use of individual devices called “dryers.”

Artificial Raw Paddy Dryer

From the point of view of construction, the essential elements of a rice dryer machine are:

– the dryer body, which contains the grains to be dried;
– The hot air generator, which allows heating the air drying;
– The fan, which allows the circulation of drying air in the grain mass.

For the artificial drying of the grains, two types of dryers are used:

– Static or batch dryers;
– Continuous dryers.

The former is inexpensive and only treat small quantities of grain; they are therefore more suited to the needs of small and medium-sized collection and processing centers.

As for the latter, they are high flow paddy drying technology that requires more complex infrastructure, additional equipment and especially a particular planning and organization. They are therefore more suitable for large centers, silos or shops, where very large quantities of product are processed.

Why Rice Mill Plant need a Consultant?

While ignoring the barriers of the income as well as the living standards of the people living in the state, country or city, rice is one of the grains that are affordable by the large population in any country. Besides, rice is stable food in most of the Asian countries. This is clear by now that a huge amount of quantity of this food item is traded to other countries, where the production is low.

While ignoring the barriers of the income as well as the living standards of the people living in the state, country or city, rice is one of the grains that are affordable by the large population in any country. Besides, rice is stable food in most of the Asian countries. This is clear by now that a huge amount of quantity of this food item is traded to other countries, where the production is low.

Now the question arises that with the right rice milling machine, we can easily produce a picture where the high output, productivity and market efficiency of the mills are required. This credit for mass production definitely goes to the rice mill consultants. These professionals are hired in large number by various mill merchants who aim for better output and working.

With the presence of milling consultants, the production and quality of the crops levels get higher. Their presence makes a big difference in the working procedures and environment. Here is how the rice mill plant consultants are a necessity these days:

Being a rice industry specialist, they help the customers with the right choice of business. This implies that irrespective of customer needs to begin the cultivation business, discount, dealership, and retail rice offering business.

Obviously, the beginning of rice plant is productive and various organization take attainable study and stage as the initial step in order to guarantee the benefits to the business. Rice mill consultants facilitate the clients with the fundamental components. For instance, prerequisite arrival, outlining and development, assets and other factors that influence the day to day working of rice machine and mills.

The need of perfect land piece and its determination is fundamental as most of the plant proprietors require highly stable capacity zone for this purpose that by now, has been processed and will be processed without much ado. Expert rice consultants have a vision to this, they make deals and perform various troublesome exercise and choose right rice processing machine. They are held responsible to consider the land zone where the production will take place.

Furthermore, the design and development are vital to accomplishing the gigantic benefits from the rice processing business. Factories and mills, under their guidance, out to produce in such a way that they permit smooth and fulfilling operations along within the arranged space. Stores and Godowns are outlined and create so as to store crude paddies and arranging the rice securely.

The consultants also take care of cleaning units, parboiling domains and various fragments reserved suitably.

Keeping up with the high rice milling equipment alongside the desired amount of production is an errand for the proprietors. These two variables add advantage to the era ability of the business. The rice mill consultants set their attention in the right direction while fitting into the interests in the rice processing hardware. They generally prescribe another rice milling process machine. In the present day, the interests, machinery, and technology offer vital protection, simple upkeep process, the higher efficiency with decreased generation cost and improved productivity of the rice mill plants.

Why Silos Are The Best Form Of Bulk Storage

“Nextech solutions, India’s leading rice mill plant manufacturer offer solutions that range from processing to storage.” When it comes to storage in agriculture, Silos provide an efficient method of storing bulk quantities of grain. Silos were used in ancient Greece specifically for the purpose of storing grains that were used over a period of time. The steep rise in the price of land has virtually made it impossible to keep buying land space in order to store food grain that is produced. Rather than opting for horizontal method of storing it is far more sensible to go vertically. Hence, the usefulness of storing food grains in bulk in silos. One can save space, prevent spillage of grains, avoid the need of gunny bags and not worry about climate changes with silos.

Agricultural silos work by creating a pressurized area within a cylindrical container; they have a closed top and a sealed bottom. The bases are sealed with organic matter such as soil whereas the closed top could be of a variety of metal or non metal stuff. Wheat, rice, pulses can be stored inside these silos which provide good protection in the narrow space for long periods. They are used and recommended by various rice mill and flour mills. Grain Products can be stored in steel silos from the time of being harvested to up till a year.

The temperature inside the silos has to be regulated to assure the grains don’t get damaged; that includes proper aeration to control the amount of humidity inside the closed container. Another important thing is to safeguard the grains from insects, chemical control within the silos is required to protect it from insects and other rodents. Being the leading rice mill plant manufacturer in the country, Nextech provides silos which are bulk storage systems for various types of food grains.

What Happens At a Flour Mill?

Dry/uncooked grains go through a process to form Flour. It is an essential component of our food cycle especially in a country like India. It is the major component of bread which is a staple diet all across the world. Grinding and pulverizing of the cereal takes place in a process called ‘milling’ in flour mills. Wheat is the most common ingredient to make flours but other ingredients like oats, rice and corn could also be milled to get flour. There are 4 main components that make wheat flour: Gluten, Germ, Bran and Endosperm.

The major varieties of flour consumed all across India are: Sooji/Rawa, Atta, Maida, Bran etc. Atta, Sooji & Maida help produce most of the staple diets meant for consumption like chapatti, sweets, and bakery-based products respectively. The bran separated after milling could be used as cattle feed.

Flour Mill Processes

The prehistoric times have witnessed Flour Milling. Obviously the methods of milling were different. The ancient methods had ‘stone grinding’ methods at their heart.

Many rural households still use the traditional techniques to grind wheat. These include: a mortar and pestle (stone club), quern and the saddle stone. Another important method used in villages is a grinding functionary called ‘Dhinki’. Dhinki needs at least two people to function.

As population increased, demand also increased. People wanted better quality flours. Hence, modern flour milling machines arrived which replaced most of the traditional methods. Originating in Hungary in the late 1800’s, spinning metal rollers came into production. Over the years, scientists have innovated & developed roller mills which are faster and give high quality flours.

Parts of Wheat Kernel & Types of Flour

It’s important to know the parts of wheat grain before learning about the various types of flour.
On the outside of the wheat grain is the nutritious bran, rich in dietary fibre. It is very high in the mineral manganese, and a brilliant source of three other minerals, namely, magnesium, selenium and phosphorus. It’s also a source of Vitamin B3 (Niacin), Vitamin B6 (Pyridoxine), iron and zinc. Inside this hard bran lies the large endosperm, the largest part of the grain. Nutritionally, it is mostly starch (Carbohydrates) and some protein. Lastly, the germ is the embryo of the grain, that sprouts and grows into a new plant. It may account for only 2.5% portion of the kernel, but the germ is a valuable source of dietary fibre, protein, Vitamin B9 (Folic acid) and Vitamin E.
Now that we have learned about the parts of wheat grain, it’s time to explore the various types of flour you would find on the shelves of your neighbourhood supermarket/ grocery store.

1. Whole Wheat Flour
Also known as whole meal flour, all parts of the grain are ground in this very healthy version. You get all the benefits of nutritious bran & germ. It is used for making chapati, paratha, whole wheat bread, and so on.

2. Refined Flour (Maida)
Also known as white flour, this is devoid of the goodness of bran & germ, ground solely out of endosperm. Its smooth texture makes it suitable for making regular (white) bread, naan, bhatura, and innumerable food preparations.

3. All Purpose Flour
A lot of people think that refined flour and all purpose flour are the same, but they are not. However, since they are so similar, they can be substituted for each-other. All purpose flour uses a combination of hard-gluten hard wheat or soft-gluten soft wheat.

Latest Technology in Flour Milling Machines

Top-quality flour provides the basis for making high-quality foods. In order to transform grain into flour of unsurpassed quality, specially designed plant and equipment is needed in addition to the knowledge of the relevant process stages.

Cleaning Action
The raw grain supplied to grain mills will typically contain impurities. Before processing, foreign seeds and contaminants that have entered the grain on the field as well as during harvesting, transportation and storage must be removed. Careful separation of the impurities will ensure a high quality of the end products. The reduction of the mineral content will have an impact on the taste and odor of the product. Moreover, it allows wear to be reduced and the service life of machinery to be extended.

Flour Milling Process

What is Flour?

Flour is the finely ground powdered material obtained from food crops like wheat, corns and pulses. Wheat flour is the most common and is used in production of breads. Dough is prepared from the wheat flour and is used to bake breads out of it. Dough prepared from the flour contains gluten which is enriched in proteins. It is gluten where gases produced from yeast and other bacteria make the dough fluffy and eventually softer.

Process of Grinding and Milling – In ancient times grinding was done by sliding rocks with wheat in between. It was a great technology for that time period. Thankfully, we have much better technology to serve us today. Let us divide this section into sub headings to go into details of flour milling:

Cleaning the Wheat – The wheat obtained from the fields is not in the best of conditions and it is obligatory to clean it thoroughly before any other thing. There is device called separator that does the job here as it removes the unwanted particles and adulterations from the raw material. Then there are aspirators which aim at removing minute particles which are much lighter that wheat grains.

Preparing the Raw Material – Once the cleaning phase is over, we can proceed further to preparing the raw material for grinding purposes. Here the wheat is dried to make sure that extra moisture is taken care of. Also wheat is sometimes conditioned with hot water or cold water treatments. Conditioning helps in improving the quality of the raw materials.

Grinding – This is the real action; here the raw material is ground to make a powder out of the wheat grains. First of all, all types of grains are blended well to form a batch of the raw material.

Now this batch is introduced to two big rollers which are ready to crush each grain into powder. These rollers are called breaker rolls. With the help of filters, the powder is collected according to their particles sizes. The finer particles with finest ones are collected at one place. With the help of vibrations, cleaning is done at this stage as well. Upon vibration, the lighter particles skip the heavier ones.

Processing – Now we have the flour with us, we just need to process it. In other words, this is the final touch before the flour is packed and dispatched. In this phase, bleaching and oxidizing agents are used to ensure good quality of the wheat flour.

These four stages sum up The Process of Flour Milling. Now the flour is ready to be used, rather baked into breads.
