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.

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.

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.

How to select excellent Rice Machine and Layout Planning

The main diet of nearly 65% of India’s population is rice. To remove rice from it, it has to be processed. The crushing of rice is the process through which its husk and bran are separated from the grains of paddy, which gives the polished rice.

It is one of the oldest professions of India and its turnover is more than 25,500 crore rupees per year. Das is processing 8.5 million tons of paddy every year. More than 60% of the country’s population receives grains and other valuable products from the main food grains. Danes are mixed with rice grains or boiled rice. Apart from this, a large number of unregistered alluring units also exist in the country.

Rice, the staple food of the Asian continent, can be stored in the shell until it should be used as food. At that stage, a Rice Mill Plant can remove the hard husk and polish the grain. This system makes it possible to keep the mill in operation throughout the year, provided that paddy rice stocks are available. Traditional rice processing, in essence, does not compete with mechanical milling, so mill owners will not have an impact on the local balance of labor, even though dietary habits may be affected.

While it is possible to choose between different types of Rice Mill Layout, the national preferences may determine that the best option is an under-runner disc mill or a mill with rubber rollers or an Engberg type mill. Often the choice depends on the ability to share existing knowledge and experience, as well as the speed with which practical skills can be obtained to support the operation in the event of problems. For example, the “under-runner” disk mill is very popular in the Indian subcontinent.

On the other hand, there is some pressure to adopt the Rice Mill Design with rubber rollers, since the latter throws a smaller amount of broken grains. In the absence of such preferences or limitations, the author would suggest that the Engberg mill is the best alternative for processing on a rural scale. This mill has a relatively low cost, is firm and easy to repair. Likewise, has few moving parts subject to wear and produces an acceptable quality of rice.

Finally, the knowledge necessary to operate and maintain this machine is not difficult to obtain. Only the smallest domestic machines are operated manually; others run on a diesel engine, which can be a significant brake on some locations. If we consider that the approximate cost of a new engine and mill is the US $ 3 000, a very high sum for a subsistence farmer, it is clear that it is necessary to plan carefully. Large producers.

In general, farmers have been the potential target market for Rice Mill Consultant, since they have the opportunity to evaluate the added value of processing the grain and, also, can install this machinery in their farms without major complications. They can build a small facility and hire someone or resort to a family member to operate the mill.

On the other hand, they can reassign part of their usual tasks to concentrate on processing, a task that requires operation and administration skills. It is likely that most farmers want to keep an article that represents such a large investment under their personal control- a task that requires operational and management skills.

Importance of Modern Rice Mill Machinery

Factually speaking, India is the largest producer and exporter of Basmati rice and one of the largest exporters of rice, in general. Rice milling is perhaps the oldest and also the biggest agro-processing industry in the country.

As it was last determined, India had a turnover of more than Rs. 25,000 cr/year and had the capacity to process approximately 85,000 tonnes of paddy each year, in turn, providing the staple food item to more than 60% of its population.

When a country witnesses economic growth along with a situation of stable supply, we see a shift in the customer preference. Their demand shifts from quantity to quality and security. If we shift our focus on modern countries, we get to see that those nations are trying and consolidating their rice milling operations into large milling facilities, whereas most of the small and medium scale milling facilities are dying away.

This clearly proves that people over there are more critical of rice quality. This growing consciousness in the rice milling market would ultimately lead to bigger, more sophisticated machinery.

Developing countries, on the other hand, face a distinct challenge of sustained productivity. In the business environment, sustained production comes across as the biggest challenge rice milling units face.

So, how can we get over this one of the most critical challenges? Well, by streamlining and automating work processes. This is the only way to enhance productivity and reach a stage of sustained productivity.

Modern, automated rice milling machines not only have more reasonable designs but also have higher milling efficiency. The quality of milling operations straightaway determines the rice output’s quality, whiteness, milling degree, grain dimensions, etc. Using modern rice milling technology can let the rice millers cater to the exact customer demand on quantity as well as quality.

Today, most of the developing nations like India, China, Nigeria, etc, owing to the low-entry barrier and high profitability have grown swiftly. However, their lack of updated processing techniques and rearward equipment is hindering the development of their country’s rice industry, as a whole.

While the surge in population has created a demand for increasing the productivity, there have been numerous cases of grain loss due to inefficient, obsolete milling equipment. Developing, rice-producing nations are said to lose about 10% of their yield each year. And this calls for an improved, automated rice milling and processing machinery.

If you’re one of those farmers suffering from the lack of adequate milling infrastructure, make sure you get in touch with Nextech Agri Solutions Pvt. Ltd. It’s an Indian-based rice milling consultant with years of experience in the rice milling industry.

The Complete Rice Production Cycle

Generally, rice plants take about 3 to 6 months to grow from seedlings to reach maturity, mostly varying according to the environmental conditions and undergo 3 distinct growth phases, which are vegetative, reproductive and ripening.

As such, rice varieties across the world are categorized into 2 groups based on their growth duration. There is a short-duration variety maturing in 100 to 120 days and a longer when taking about 150 days.

Let’s now take a look at how rice is grown:

1. Seed Quality Analysis & Selection

To realize the yield potential, a seed must be grown, harvested and finally processed justly. Also, healthy, good quality seeds carry the potential of increasing the yield by 20%. Some of the benefits of using good quality seeds are:
– Decreased seeding rates
– Increased crop emergence
– Decreased need for replanting
– Vigorous early growth
– Increased resistance to pests, insects and natural diseases
– Reduced weed growth

A good seed is one which is pure, i.e. coming from single variety, uniform in size, viable and free of pathogens, insects and seed-borne diseases.

2. Land Preparation

It’s mandatory to prepare the land and render it suitable for planting seeds. The soil, before planting, should be in the best physical condition if one expects an optimum plant growth. Essentially, land preparation involves plowing, digging up or harrowing to till and leveling the soil.

3. Crop Establishment

There are two common practices for planting rice seeds. These are:
– Direct seeding: Done either by hand or machine, direct seeding involves broadcasting pre-germinated/dry seeds. Generally, dry seeds are manually planted into the soil in ecosystems that are rain-fed, while pre-germinated seeds are planted in areas with dry soil.
– Transplanting: More popular of the two, transplanting involves the transfer of pre-germinated seeds from seedbed to wet fields. Although it requires less seeds and is a particularly effective method to control weeds, it is labour intensive.

4. Water & Nutrient Management

Since rice is grown in bunded fields which are flooded for up-to 10 days prior to the harvest, it’s fairly easy to determine that rice is extremely sensitive to water shortage. Contributing to this fact is its semi-aquatic ancestry. Keep in mind the following water management tips for maximum rice yields:
– Construct field channels
– Optimum land preparation
– Leveling the soil
– Construct bunds to limit any water loss

It’s also important to keep in mind that rice plant requires different nutrition at different stages. Nutrition management is a chief component of rice production.

5. Crop Health

Globally, farmers annually lose about 35% of their crops to plant diseases and pests. Rodents, insects, viruses, weeds, etc. are arch nemesis of rice plant. It’s important for rice farmers to understand how the crops interact with the pests and avoid such conditions. Certain tips that could help are:
– Land and water management
– Hand weeding
– Herbicides
– Good cleaning of farming equipments
– Pest resistant seed varieties

6. Harvest

Harvesting involves the collection of mature rice plants. AS we’ve discussed above, rice crops generally take 100 to 150 days to mature, depending on their growth duration. To minimize grain damage and for maximum yield, it’s mandatory to involve good harvesting techniques. It can be done either manually or using a combine harvester. Harvesting includes:
– Reaping
– Threshing
– Cleaning
– Hauling
– Field drying
– Stacking
– Packaging

Rice Production: Pre-Planting Activities

This post by Nextech Agri Solutions aims to provide practical knowledge necessary for small-scale farmers entering the rice production business. Beginning with the pre-planting activities, this post will cover the rice varieties to choose from, information on seed quality, crop calendar and land preparation.

These are 4 of the most important activities before the rice planting, and needs to be taken care of if one anticipates a high, prosperous yield.

1. Selecting the rice variety

It’s fairly important to begin with healthy seeds of a locally adapted rice variety. This ensures that the crop has a high yield and attracts good market price, and is also cheaper than importing high-potential varieties from other countries.

Mentioned below are the characteristic features a good rice variety must possess:
– Appreciable cooking characteristics, colour, aroma, taste and shape
– High selling price
– Stability
– Optimum yield over multiple seasons
– High tillering capability for competing against weed
– Tolerance against crop diseases and pests
– Resistance to droughts and floods
– Exact maturity length that matches the growing season

2. Seed quality

The crop quality entirely depends on the seeds sown. Since seeds are the foundation of any crop, it becomes pivotal that one ensures that the seeds utilized are of optimal quality.

Good quality seeds ensure the following benefits:
– Increased uniformity
– Less replanting
– Lower seed rate
– Better emergence (greater than 70%)
– High initial growth
– Increased resistance against pests, insects and diseases
– Decreased weed
– Increased yield

The following factors are used to determine the quality of rice:
– Varietal purity: It involves the percentage of germination, moisture content, weed, other crop seeds, stones and red rice seeds.
– Viability: Germination potential, moisture level and vigour are used to determine the seed viability.

The germination rate is indicative of seed vigor. A swift rate of germination shows that the seed will establish itself well in the field stage. Weaker seeds are easily affected by environmental stress and are known to produce weaker seedlings.
– Moisture Content: As such, moisture content should be less than 14%

3. Crop Calendar

Crop calendar provides for a reliable framework for all the subsequent farming activities.
It provides a clear schedule from seed sowing to storage and allows the farmers to:
– Decide the input purchase
– Prepare a budget for all the activities
– Determine labour, capital and credit requirement
– Prepare land and harvest

Based on local experience and with the help of agricultural promoters, determine the best date to plant. Determine the time it takes for your chosen variety to harvest. Establish the labour and finance requirements at each of the subsequent steps, i.e. plowing, weeding, fertilizing, etc.

4. Land Preparation

This is the final step before we begin with the planting. It is an important step which helps control weeds, recycles plant nutrients and provides for a sustainable surface and soil mass for direct seeding.

As such, land preparation either begins during fallow, i.e. the period wherein a field is left uncultivated so it regains its fertility, or immediately after the previous harvest. Moreover, it usually takes around a month for complete land preparation.

It typically involves 3 different stages which are:
– Clearing the field
– Creating compost from rice residues
– Planting cover crops to enrich soil and suppress weeds

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.

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

Inaccurate moisture testing could lead to:

  1. Grain loss if excessively dried
  2. Increased drying costs and paddy loss if milled at high moisture content
  3. Lower head rice, when milled at wrong moisture content
  4. Weight loss when dried excessively
  5. Mold development
  6. Heat buildup in the grain
  7. Pest infestation
  8. Discoloration
  9. Reduced yield
  10. 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 the 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”.

Why Are Rice Mill Consultants Important?

Ignoring the barriers of the income and the living standards of the people living in any city, state or country, rice is affordable by the maximum chunk of the population. Besides this, rice is the staple food form in many states and many Asian countries. This is a clear indication that a huge amount of the diverse quantities of this food item is and will be traded to other countries, which do not have sufficient production.

By learning all this, we can form a picture of the huge output, productivity, as well as the market efficiency of the rice mills which are located at various production locations. The credit of such an immense degree of production should definitely go to the rice mill consultants who are being hired in greater numbers by many mill merchants to have a better working and output.

Without the presence of these milling consultants, the production levels might vary. Their presence is a must for a better working environment and procedure.

The requirement of a perfect piece of land and its determination are of fundamental significance as the plant proprietors require enormous stable or capacity zone for the creation purpose that has as of now been processed and that will be processed without further ado. Experts concentrate on the regions that have tallness, as low-lying locales make dealing with and performing of various exercises troublesome. They likewise consider the zone to which the land has a place, it assumes an indispensable part in the transportation of crude material and completed items. Significant consideration towards a true blue waste structure in the zone to which arrive has a place is likewise paid.

The design and development are impressively vital in accomplishing gigantic benefits from the rice processing business. Factories ought to be produced in a way that they permit smooth operations and fullest use of perfect space. Godowns and stores ought to be outlined and created to store crude paddy and arranged rice securely. Taking care of units, cleaning units, parboiling domains and different fragments ought to be reserved suitably.

Keeping up high calibre alongside required amount is a testing errand for factory proprietors, and these two variables straightforwardly add to benefit era ability of the business. The rice mill consultants have their attention on the right determination and fitting interest in the rice process hardware, and they generally prescribe for another other than a revamped machine. Interest in present day advancements and devices can possibly meet quality principles and deliver high amount also. Further, present day machines offer vitality protection, simple upkeep and high efficiency that decreases the generation cost and improve productivity of the rice mill plant.

Rice Milling Industry In India: Things You Need to Know

About 65% of India’s population consumes rice, making it one of the most important food crops in the country. Rice, in its raw form cannot be consumed and therefore, the need for processing surfaces. Typically, a milling process involves 3 basic stages:

  1. Husking
  2. Whitening/polishing
  3. Blending, grading and packaging

In modern mills, a number of additional adjustments are present that not only ease out the process, but also produce better quality rice with higher yields. Modern milling process involves:

  • Pre-Cleaning: Separating impurities and unfilled grains
  • De-Stoning: Removing stones from paddy
  • Husking: Removing husk from paddy
  • Husk Aspiration: Husk separation from unhusked paddy/brown rice
  • Paddy Separation: Separating unhusked paddy from brown rice
  • Polishing/Whitening: Removing bran layer and germs and improving the appearance
