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.

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.
