Problems in High Moisture Paddy

Rice is perhaps the grain that has been cultivated for a very long time. It is occupying approximately 9% of the total arable land. It is the second cereal in significance for the human diet, after wheat. It is at present the food base of a two-third population of the world.

It is well known that paddy drying is essential for its safe storage. You can expect a better storability of the paddy if the moisture content is within safe limits. As a rule of thumb, 1 % decrease in the moisture content of the grain doubles the storage life. But drying of paddy is not easy. The high humidity is a serious factor obstructing appropriate drying and storage of grains.

A certain level of moisture content should be maintained in rice and this depends on the time for which it is going to be stored.

  • 18% for 2 weeks
  • 14% or less a month
  • 13% or less for 8-12 months
  • 9% or less for long-term storage

There are many processes of drying:

    1. Field drying: It is done in a field after cutting rice panicles in fields and then stacking them into piles and racks. It is most primitive of them all.

 

    1. Sun drying: This labor-intensive method is preferred by small farmers. This is inexpensive way of drying paddy

 

    1. In-store drying: Paddy is dried during storage by controlling the level of humidity in the air. It is a slow process.

 

  1. Batch dryer: It may lead to uneven drying and usually used by farmers and rice millers.

Storage of high moisture grain is a grave problem farmer facing. Traditional methods of sun drying are still in practice but have sure disadvantages such as

  • unreliability
  • uncontrolled heating of grains
  • thermal stresses leading to grain fissures
  • vulnerability to infestation in open
  • Losses due to birds

Use of mechanical paddy drying offers a number of advantages over old-school methods and some of the benefits are as follows –

  1. Sustaining the quality of paddy
  2. Safe drying even during rain and at night
  3. Convenient control of drying parameters
  4. Significant saving on the labor cost

For the best drying, you must take advantage of the technology. You must go to the best paddy drying providers. Nextech Solutions have experts which provide complete solutions related to rice.

Rice Mill Plants – Past and Current Technology in Milling

Rice is one of the most important food crop across the world that is processed in the rice milling plants with respect to the international standards keeping in mind the uniformity and the basic quality of the grain. There are different rice milling machinery and Rice Milling equipment used for the proper processing of rice and ensure its maximum processing capacity in less amount of time.

The most important productional factor considered for its processing is the use of energy. Energy is one of the demanding items and the vital source to measure the cost of the finalized finished product. For the production of rice, the energy-consuming equipment used includes blowers, elevators, motors, boilers and steam distribution, and many more. The efficiency of the product (rice) depends on the utilities maintained by the rice production mills such as electricity, air, water, labor, etc.

Many of the rice plants in India and also in the different parts of the world adhere to several procedures for rice processing such as drying of rice, cleaning of rice, milling, whitening, polishing, grading, blending, sorting and packaging. There are different types of sorters and separators used for the rice to be free from any type of dust, fungal infections, plastic granules, unwanted grain, etc. Some of them include:

Rice Huskers: These huskers remove the husk (outer covering) from the paddy rice during the processing.

Paddy Separators: It makes the brown rice more efficient.

Plano Shifters: This makes the rice more uniform and give rice proper size and grading with a high speed.

Color Sorters: These color sorters give a proper color to the rice and define its shade.

The basic structure and the process followed in the rice milling industries and rice milling plants include:
1. Quantity of Rice (In Abundance)
2. Pre – Cleaning
3. Steaming
4. Drying
5. Packaging
6. Grading and Sorting
7. Polishing
8. Removal of Husk

Initially, the basic rice cultivation process requires the complete preparation for the technological projects and the set-up of the milling plant. Many layouts, specifications, selection of appropriate milling equipments and units are planned for the efficient running of the milling industry. Further the assessment reports are also prepared keeping in mind the benefits with the selection of experienced personnel.

There are different types of methods used in the rice milling industries. In the earlier days, conventional methods were used for paddy processing using the steel hullers and the rice processing process mentioned in the above flowchart was carried out manually. This method seems to be the inefficient method as the chances or the profits to rise at a higher level often degrades. The marketing costs and the net returns tend to decrease that prevents the consumers from earning accountable outputs in time. Further, the latest and modern rice milling units make use of more efficient technology that hep them yield a large net return and the calculated costs become better for the large quantity of paddy. Roughly, we can say that capacity utilization using the modern methods is approximately 70% in comparison to the conventional methods used (approx. 45%). Rice is the staple food and is one of the man source among all the food grains

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.

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.
