How Does A Rice Mill Work?

Rice is the staple food in most of the country, including India. People love to eat rice, which is essential for our diet; deficiency in the same may cause Niacin disease. But hardly anyone knows how the paddy gets converted into rice and the importance of the rice mill business.

Rice is a Kharif crop that is sown during the onset of monsoon, i.e., between June and July, and harvested in December. After the harvesting is done, farmers sell their rice to the rice mill owner, and in the mill, further process is done to achieve the fine-quality of rice.

If you are a farmer or entrepreneur and planning to enter the rice business, then just read this full article to know about different rice processes, and the importance of mill and rice mill design.

Step By Step Processes Of How Rice Mill Works?

1]Cleaning

When the rice mill receives the rice from the farmer, the first process done is cleaning. It helps to separate all impurities like straw, dust, clay, and sand. Cleaning the rice helps to increase the oil percentage in the bran.

2] Stone Separation

Once cleaning is done, the second process is destining, in which the stones are removed. As we know, during harvesting, many stones come along with the paddy, and the removal of the same is a must.

3] De-Husking

After cleaning and stone separation, the rice is put in the de-husking machine to separate the husk and paddy. In this process, paddy grain is passed through the abrasive surface, and due to the friction, the husk is removed from the paddy grains.

4] Paddy Separation

During the de-husking process in the rice mill, some unhooked paddy rice remains, and the removal of the same is done by the paddy separation process.

5] Rice Polishing

Rice polishing is usually done in the rice to remove the bran layer from the paddy either through friction polisher or abrasive.

6] Rice Parboiling

Rice Parboiling is a three-layered process in which raw rice is sowed in warm or cold water, and then steam is passed at high pressure to gelatinize the rice starch. In the third layer, the final product goes through the drying process.

7] Sorting Of Rice

Sorting of rice at the rice mill is done before packaging, and it is very necessary to sort the broken and long grains from the rice stock. After sorting, the rice is graded based on quality.

8] Packaging

Last but not least, the packaging is the final process, in which the rice is packaged in gunnies or plastic sacks, and thereafter it is weighed. After the above process, a seal is marked to show the weight and grade of the rice.


To Wrap Up

Rice travels a long distance to come into the market from the field. Rice mill is also a lucrative business, and if you want to enter into this business, you need investment, machinery, and much more. Furthermore, proper information for rice mill works is also essential as the same will help you to yield good quality rice from the mill.

Are you wondering how you can smoothly optimize rice mill plant? We will help you with the same.

 

Optimize Rice Mill Plant

Optimizing the mill plant is essential but is also full of challenges. The first step in the process is to find good-quality paddy. You have to ensure that the paddy you’re using is pure and of high quality.

 

Other things that will help in optimizing the rice mill plant are below:

  • Uniformly mature kernels: With uniform mature seeds, you can reduce the chances of wastage.
  • Uniform size and shape: The plant or any automated machine works faster and more effectively with uniform size and shape.
  • Free of empty or half-filled grains: The work efficiency increases automatically if your raw material is free of open or half-filled grains.
  • Free of contaminants such as stones and weed seeds: The material free of contaminants is fast to process.
  • Don’t waste material: It is essential to focus on not wasting the material for increased profit and improved efficiency. Be it energy, human resources, raw material, or any other assets, make sure that you’re not wasting any of these or utilizing them smartly.
  • Improve training: To optimize the rice mill plant, it is essential to provide the proper training to your staff. A good rice mill plant, or any factory/plant for that matter, can offer increased efficiency only with a well-trained staff.
  • Quantify everything: One of the significant steps in optimizing a rice mill plant; you must quantify everything to increase productivity. If you’re not quantifying things, you’ll never be able to gauge the exact profit and the investment. People who want to stay in the industry for a longer time should make it a habit to quantify everything precisely.

 

So these were some ways with which you can easily optimize your rice mill plant for better efficiency. You can also connect with a rice mill consultant to guide you through. If you bring these measures into practice at your rice mill plant, you’ll start noticing a positive change in your business.

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.

PADDY PROCESSING

 

Rice procurement is a long and winding process wherein it ’s cultivated by farmers and after being made fit for factories by usage of threshers and harvesters, it reaches the factories. After this, rice processing is an equally complex process.

    • The Pre-Cleaner is undertaken to resolve pre-cleaning issues that may arise after the transportation.

 

    • Paddy Dryers are employed to ensure rice is uniformly dried to be fit for processing. This usually requires preprocessing and minimizes moisture content before storing it in warehouses.

 

    • De-Husking A fully automatic rubber roll control system ensures that a prefixed percentage of paddy is mixed before being fed to the tray of separators.

 

    • Paddy Separators To set apart rice from its kernels, these machines move sideways to roll the mixture downwards.

 

    • Polishers Moving friction in the moving rice grains ensures an even polishing. At this stage segregation into the light and heavy seeds, cereal and granular materials are accomplished through Fine Cleaners.

 

    • The final stage is Grading and Sorting where stringent quality control processes by experts ensure the perfect grains are shipped out of the factory premises.
