Some Major Factors That Affect Milling Quality

Do you want to explore the major factors that affect milling quality? Then this guide can help you explore such production factors.

Do you want to explore the major factors that affect milling quality? Then this guide can help you explore such production factors. In general, the quality of milling can be effectively influenced by any production factor that affects kernel strength. It is entirely responsible for the kernel to withstand the bran removal and hulling process without breaking apart.

Impact Of Rice Milling Yield:

The rice milling yield can be effectively quantified by two numbers such as 58/70.

Here the number 70 represents the milled rice yield. It can be determined by the total amount of white rice remaining after the milling and hulling process. You can calculate it by dividing the total mass of the milled rice by the original mass of rough rice before processing. Then it can typically range from 68 to 72% very effectively.

Then the number 58 represents the head rice yield. You can determine it by exploring the total amount of milled rice kernels that can become whole. Here the whole milled kernels can remain 3/4th or more than their original length.

The head rice yield can be effectively calculated by dividing the total mass of head rice by the original mass of rough rice. Here the head rice yield may vary from zero. It means that all kernels are broken based on the milled rice yield. It can be similar to 68 to 72% with no kernels broken.

Explore Milling Quality:

The milling quality can often be expressed as the head rice yield ratio to the milled rice yield. For instance, a 58/70 value can indicate the milled rice yield of 70%, head rice yield of 58% and 12% broken kernels (The difference between those two values).

After that, the harvest moisture content will have an extraordinary impact on rice milling quality around the producer’s control. Here the head rice yield may differ with the moisture content from which the rice has been harvested.

Based on the weather conditions, the harvest moisture content may vary and have other impacts. You can grab 22 to 24% for medium-grains and 19 to 21% for long-grain cultivars.

When the rice matures, kernels on the panicle occur at different moisture contents. It will mainly represent the kernel strength and maturity levels. Some kernels are green or immature with more than 22% moisture, whereas others are dry kernels with less than 14% moisture.

Final Verdict:

From the scenario mentioned above, you now know the factors affecting milling quality. You can get in touch with the leading rice mill consultant at Nextech Grain Processing and Engineering Solutions Pvt. Ltd to overcome serious factors. Finally, you can stay away from significant issues and enhance milling quality.

A Rice Milling Business plan needs to be formulated and is critical as it lays out in details the investments required, the number of people for hire, profit and loss forecasts, likely cash flow analysis & predictions and the projections for the proposed rice mill business. Employing Rice Mill Project Consultant is the key point in acquiring Rice Mill Engineers & Designers, & Rice Mill Machinery necessary for the highly advanced and often automated rice mill.

MAIN PROCESSES OF A WHOLE RICE MILLING PLANT

Proto Rice Mill stage

At this stage, the rice field needs to be prepared for planting. Steps like Paddy transplanting and Rice harvesting including reaping, stacking, handling, threshing, cleaning, and hauling are critical and are all performed by Rice Combine Harvesters.

Rice processing steps

After arriving at the mill, it goes through a series of sorting machines to separate the kernels from any debris. The rough rice is made to pass through “Sheller” machines. Brown rice is left behind, that is then worked by machines revealing white or “polished” rice.

Post Production Processes

1. Fully automatic rice mill plant ensure pre-cleaning, de-husking, paddy separating, milling, grading et al. Nextech has expertise of Rice Mill Machine Design, Rice Milling Plant Layout Design to set up the optimized rice plant.

2. The Pre-cleaning process through Paddy cleaner extracts all impurities like dust, straw, sand, clay and heavy particles from the paddy. Rice dehusking: Removes the husk and bran from the paddy rice leaving a minimum broken grain.

3. Paddy separating separates the dehusked paddy & brown rice. White rice produced by machines that remove the bran layers through rubbing revealing “white”/”polished” rice.

4. Rice grading separate immature grains to ensure independent milling of graded lots Weighing and packing is now undertaken for transport to the customer.

5. Environment-friendly steps- millers have switched to clean fuel like crop stalk and straw, rice husk, etc. As the leading Rice Mill Engineers & Designers & Rice Mill Consultant, Nextech Solutions– provide support at every stage.

Modern Rice Milling Process

The Rice Milling process has changed drastically over the years. The modern rice milling process combines several operations to generate a higher yield and produce a better quality of white rice from paddy or rough rice. If you’re new to rice milling, it’s crucial to contact rice mill consultants for better productivity.

What is the Milling Process?

Rice Milling is the process of removing the husk and bran layers from the paddy and producing a white rice kernel that is free of impurities.

Most milled rice is composed of around 20% husk, 8 – 12% bran depending on the milling degree, and 69% starchy endosperm.

Modern Rice Milling Process

There are five major components of the modern rice milling process. Let’s have a look at each of them in-depth.

1.Cleaning

The primary aim of the cleaning process is to remove foreign particles from paddies such as stones, immature grains, and other impurities. Cleaning is done before the processing of grains. Cleaning does not help in removing the dust from the raw particle. Instead, it helps in attaining high milling recoveries.

Here are a few ways by which cleaning before husking and whitening are beneficial:

Make the rice mill look neat and hygienic.
Save the wastage of paddy along with stones.
Reduce grain breakdowns.
Increase the milling capacity.
The cleaning process involves sending paddy through three machines: pre-cleaner, classifier, and de-stoner.

2.Dehusking or dehulling

In dehusking or dehulling, the chaff (the outer husks) is removed from the rice grains. The conventional hulling machines have a low shelling degree (of about 60-70%). These machines increase the breakage of rice and are not as effective in separating paddy from brown rice. Therefore, it is crucial to install pneumatic rubber shellers, tray separators, and husk separators in the dehusking section of your mill. This will help you:

Increase the milling capacity by 5%.
Reduce the breakage of rice.
Minimize the expenses on consumables and downtimes.
Eliminate admixtures such as oversized rice kernels and immature grains.

3.Whitening or polishing

The whitening or polishing process helps in removing the bran from rice. Thereby making the rice consumable and suitable for market requirements. Installing vertical whiteners and silky polishers in your Modern Rice Mill will help you:

Enhance whiteness.
Increase head rice yield by reducing breakage.
Enhance the appearance of rice kernels.

4.Grading

Grading helps mill owners achieve a better yield of head rice and retain broken rice for further processing. Installing thickness graders, rotary sifter, and length grader will help you:

Effectively separate broken paddy from head rice.
Limit the percentage of broken rice in head rice effectively.
Increase productivity and reduce grain separating time.

5.Colour Sorting

Colour sorting is the process of removing unrefined grains based on the colour of the rice. Modern colour sorting machines are equipped with features like auto sorting control systems, image capturing systems that are capable of storing up to 200 profiles, and a quality ejector system that monitors the quality of the output.

If you’re looking to improve the quality or quantity of milled rice, then implementing the modern rice milling process can be your best bet.

We at Nextech Solutions have the Best Rice Mill Engineers And Designers who can help you with grain milling solutions and adapt the modern rice milling process. From rice mill plant design to rice mill setup, we can help you with everything you need.

Modernisation Of The Rice Milling Industry

The process of converting paddy into Rice by using modern technologies is called modernisation of the Rice Milling Industry. This process helps easily remove the husks, dust, extracting the kernel of Rice, and produce edible Rice by using high tech machines.

The process of converting paddy into Rice by using modern technologies is called modernization of the Rice Milling Industry. This process helps easily remove the husks, dust, extracting the kernel of Rice, and produce edible Rice by using high-tech machines. You can be able to get more Rice with the involvement of the Modern Rice Milling process. Many industries are likely to change their old plant to the latest technology. Various operations are being followed all over in milling for the production of the end product named Rice.

The Processes Involved In Modern Rice Milling:

There are eight processes involved in Modern Rice Milling, and every process is carried out in order. Each process depends on others and waits until the completion of the previous process. But it is a rare scene because of several tons of paddy involved. Modern rice milling delivers polished Rice with great quality to the customers and retailers. Modern rice milling machines are a great cost to plants. But it is worth its cost and gives a huge profit to rice merchants.

Pre-cleaning

Dehusking or Dehulling

Separation of Paddy

Polishing or Whitening

White Rice Separation

Mixing of Rice

Polishing of Mist

Packing and weighing of Rice

Working Of Modern Rice Milling Industry:

Pre-cleaning is an initial process, and it increases the chance of Dehulling. This process prepares paddy for the easy removal of husks. The de-husking process completely removes husks bypassing paddy with different speeds in abrasive surfaces. Brown rice is converted to Paddy Rice by the paddy separation process. Three or four whitening machines are connected to polishing the Rice by removing gems and brans.

Large and small Rice are being collected from separating white Rice after polishing. The rice mixing process involves volumetric mixers for mixing Rice in the right proportion depending on the country. In mist polishing, the final mist of water is applied to Rice before packing. After this, the Rice Milling Industry uses weighing mechanisms to pack Rice and ready to sell. These steps are being followed for packing all varieties of paddy crops. Specialized operators are being involved in the rice machine operation.

Responsibilities Of Rice Mill Consultants:

The rice mill merchants assist consultants for higher production with great quality. They use consultants to attract customers for the right choice of selling good products. Instant development in Rice’s production in the day-to-day process influences consultants to make great dealing with a client. Rice Mill Consultants also look after each unit in the process of milling. They take care of the efficiency of work and provide guidelines for industries. They involve choosing the quality rice machines to operate without giving problems at production time. Thus the consultants of this field help the merchants to have a good deal of business profitably.

Rice Plantation and its Growth

As such, the rice production cycle is divided into 3 distinct stages. These are pre-planting, growth and post-production. In one of our previous blogs, we thoroughly discussed the initial stage of rice production, i.e. the pre-planting process.

With this blog, we’d now move to the next step of rice production process, which is the growth stage. The rice growth stage includes 5 different processes. These are:

Rice plantation
Water management
Managing nutrients
Weed control
Disease and pest management

1. Rice Planting

Rice planting begins once the land has been prepared. As such, in rice farming, 4 different methods of cultivation exist.

These are mentioned as follows:

- Direct seeding or broadcasting: Broadcasting involves sowing the seeds directly by hand and is suitable for areas with infertile soil and dry land.

- Transplanting: Practiced where the soil fertility is optimum, transplanting is the most popular seed establishing method. It involves the transfer of pre-germinated seedlings from seedbed to the main field.

- Drilling: Confined to peninsular locations, this method only requires 2 persons; one for ploughing land and the other for planting seeds.

Japanese technique: The Japanese method requires seeds to be sown on raised nursery beds which should further be transplanted in rows. It requires timely fertigation, i.e. injecting fertilizers and other chemicals into the soils, and weeding and is only used for high-yield rice varieties.

2. Water Management

Everyone involved in the process of rice production knows that rice of extremely sensitive to water shortage. Generally, rice is grown in fields that are continuously flooded for at least 10 days, almost a week until beginning the harvest. This is particularly important for lowland rice. This constant flooding ensures water sufficiency while controlling weeds.

Since there is a global shortage of water, it’s important to follow water management practices like constructing field channels, prepare and level land, and construct bunds.

3. Manage Nutrients

During the growth stage, rice plants require nutrients to grow and develop. Also, applying nutrients to the crop is also one of the most crucial steps for improving soil fertility and prevents nutrient imbalance in the field.

4. Weed Management

To prevent yield losses, bring down production cost and maintain grain quality, it’s fairly important to prevent and control weeds. Since weeds compete equally for sunlight, water and nutrients, it becomes all the more important to prevent them. Not just during the crop growth, weed management should be practiced during land preparation and in the nursery as well.

5. Disease and Pest Management

Weed is not the only enemy that we face during rice production; the rice plant faces a lot of foes during its growth. These are insects, rodents, viruses and diseases. On an average, each year, farmers lose about 37% of their crops to diseases and pests. It is, therefore, important for farmers to understand how pests and other enemies interact with crops and come up with necessary management practices.

They need to:

Clean the field and farming equipment
Use pest resistant varieties
Avoid over fertilizing
Implement natural pest inhibitors
Refrain from applying pesticides during the initial 40 days of seed planting

For detailed information on the above-mentioned steps and any other information on rice growth, rice milling and rice storage, one should contact Nextech Agri Solutions, a New Delhi based rice planting and rice milling consultant.

How to Determine the Moisture Content in Paddy?

Moisture content, as we define it, is the weight of water in rice or paddy expressed in percentage. In post-harvest handling, MC is stated on a wet basis (MCwb). Simply put, it’s percentage of water in a wet grain.
The importance of measuring moisture content

It’s imperative to determine accurate moisture content. This is done with a view to effectively manage and market paddy, for each purpose requires different moisture content.

The importance of measuring moisture content

It’s imperative to determine accurate moisture content. This is done with a view to effectively manage and market paddy, for each purpose requires different moisture content.

For e.g. 18% MC for storing grains up-to 2 weeks, 9% for long-term storage, etc.

Inaccurate moisture testing could lead to:

Grain loss if excessively dried
Increased drying costs and paddy loss if milled at high moisture content
Lower head rice, when milled at wrong moisture content
Weight loss when dried excessively
Mold development
Heat buildup in the grain
Pest infestation
Discoloration
Reduced yield
Loss of germination

How to measure paddy moisture content?

There are two widely used methods to measure moisture content. These are:

1. Primary Method: It is based on weight measurements and is ramified into 2 steps:
– Oven method
– Infrared method
2. Secondary Method: It involves measuring the electrical traits of grains using an electronic instrument

There are a number of different portable moisture meters available in the market. One simply has to make sure that the chosen meter is suitable for harvesting paddy or grains to be milled, depending on whatever you’re planning to do.

Let’s take a look at the moisture content required for different post-production activities:

Paddy Harvesting

When harvesting paddy, one needs to keep in mind that lower moisture content can possibly lead to grain shattering and higher moisture content can lead to losses owing to poor grain quality.
– Ideal moisture content: 20-25%
– Primary losses: Grain shattering and poor quality

Paddy Threshing
– Ideal moisture content: 20% for manual threshing and 20-25% for mechanical threshing
– Primary losses: Breakage/cracking, grain damage and partial threshing

Paddy Drying

The drying process should begin within 24 hours of harvest. Otherwise, there’s a very high possibility of quality deterioration and grain damage.

It should also be noted that seeds should be dried well below 12% moisture content while grains to below 14%.
– Ideal moisture content: 14% or lower
– Primary losses: Discoloration, spoilage and fungal infestation

Rice Storage
– Ideal moisture content:
14% or less if it’s to be milled or stored or a month
Less than 13% for storage up-to 12 months
12% for seed storage
– Primary losses: Pest infestation, fungal infection, loss of germination, etc.

Rice Milling
– Ideal moisture content: 13-14%
– Primary losses: Cracking and breakage

I sincerely hope this post would be helpful to all those planning to venture into the business of rice processing and milling. For any further assistance, feel free to contact Nextech Agri Solutions, one of the best Rice Mill Consultants in India.

Nigerian Federal Government all set to install 110 Rice Milling Machines

The Federal Government of Nigeria recently acquired 110 rice milling machines, which, if everything goes as per the set plans, would be installed in different parts of the country. The installation process is expected to continue until the end of July, and is aimed to boost the dwindling production of rice in the country.

This development was confirmed by Malam Garba Shehu, who is the Senior Special Assistant on Media and Publicity to President Buhari, on his Facebook page, in Abuja.

Shehu, the president’s spokesperson stirred a national debate with his claim of Nigeria being the second largest producer of rice. Following a rice revolution that commenced in 2016, Nigeria achieved the position for being the second largest rice producer in the world.

Quoting an investigative media report, Shehu also remarked that 48,000 millionaires emerged in the state of Kebbi alone, for growing rice.

Shehu also claimed that over-reliance on oil has destroyed the country and that they are not in a position to continue. And the diversification of economy aims at distributing money across ordinary Nigerian citizens, ultimately leading to widespread prosperity across the whole country.

The president’s aide wants the country to be proud of the country’s ongoing agricultural revolution.

However, he also stated that the officials of the Federal Ministry of Agriculture are going to come up with latest development on Nigeria’s rice production.

Mr. Shehu’s Facebook post further read ‘’we’re not the first to say that Nigeria has reached second position in the world in terms of rice production. CNN, with their global reach also said the same thing. CNN is not a frivolous source and there’s reason to believe them.’’

“While the country waits for the actual numbers to come from the Food and Agricultural Organization, the government will be collating their own figures. Nigeria has been feeding a lot of parts from the north, west and central Africa since the last October and most of them have been shopping for millet, sesame, rice and sorghum in Nigeria.”

“In order to support the booming rice industry, the Federal Government acquired 110 rice milling machines. A lot is happening in the country and all of us should be proud of it”.

Who Are We In A Nutshell

We are not going to waste your time tonight giving a brief on how important a crop paddy is. Or how important rice is in the Indian subcontinent. Instead, we are going to cut the chase and talk about who we are, and what do we do.

Rice Milling is a combination of processes that starts with pre-cleaning, when impure paddy arrives from the field to the rice mill, and ends with the weighing and packing of the whitened, polished, blended rice. Rice without milling, cannot be consumed. Even if you eat brown rice, the paddy needs to be pre-cleaned, de-stoned and husked. We offer solutions for the setting up of rice milling plants. But that is not it, as a company promoted by two industry veterans, we also possess extensive knowledge of flour milling, bulk storage and silos and Spices Cleaning & Grading.

Pulses are a major component of Indian cuisine because a majority of our country’s people are vegetarian, and lentils form a great source of protein. Since they are economic, and offer so much variety, they can be cooked pretty much on an everyday basis. Since different dals have different characteristics, the processes of milling are different.

Indian food is incomplete without spices. A lot of spices are sold in our domestic markets, and a lot of them are exported. We help you with spice cleaning, grading and sorting.

That was about us – in a nutshell. We highly recommend you to go through our services page to know about us more. We highly recommend you to drop a query in the Contact Us section and avail our highly professional services.

Basmati Rice Manufacturing Process

Basmati Rice is a variety of rice, which is particularly grown in the Punjab area of India. Basmati Rice is characteristically longer than other forms of rice. What’s more, it is known to possess a unique aromatic smell. This smell is due to the presence of a chemical compound known as 2-acetyl-1-pyrroline. Although this chemical compound is found in various types of rice, Basmati Rice comprises 12 times of the compound as compared to other types of rice.

Basmati Rice is of Two Types: White Basmati Rice and Brown Basmati Rice. Both types differ in nutritional value and appearance.

Basmati Rice Manufacturing Process is similar to that of other rice types. Let us take a look at the Basmati Rice manufacturing process:

Harvesting:

When the plants of Basmati Rice ripens in around 3 months, the harvest is ready. The fields can be harvested by hands or by machines, depending upon the size of the operation. Brown Basmati Rice can be obtained just after harvesting, all it needs is some cleaning and hulling.

Drying:

Around 20 percent moisture is found in Basmati Rice at the time of harvesting, which must be removed in order to proceed further. The moisture is removed by drying out the harvest. The drying can be done with the help of artificially heated air or by simply utilizing sunshine.

Hulling:

Hulling is a process in which the dried rice is rolled on with machines. With the help of rolling action, the hull is loosened and eventually removed from the rice. The hulled grains are separated from unhulled grains by shaking the kernels. The heavier unhulled grains get separated from lighter rice.

Milling:

Brown rice is more prone to getting spoiled and this is why brown rice is converted into white rice. Milling includes two-stage hulling in which the bran layer is efficiently removed from the rice. After the removal of the bran layer, rice is further polished to make it look more presentable.

Enriching:

The polished rice lacks certain nutrients and vitamins. The polished rice is here replenished with some important nutrients and vitamins to make it more suitable for consumption.

Once these stages are finished, we are left with pure eatable rice grains. These grains are then packed into batches and processed for transportation to different retailers. The packing makes sure that the rice does not get spoiled while storing or transportation.
