Processing at IRM

1. Paddy Selection

After harvesting in Oct - Dec, farmers bring in their produce to the rice mills for sale. IRM has its purchase points established in the heart of major basmati growing areas in Punjab and hence remains in easy reach of the farmers.

Before a particular lot of paddy is purchased, it is subjected to various tests. This includes inspection by a team of experienced selectors and paddy-experts, tests for moisture contents, kett-test, field admixture etc. Samples are then processed in the mini mill to determine yield, kett-test and after-cooking characteristics. A lot is purchased only when it meets the stringent quality requirements of the company.

Selection of paddy is a process where a rice mill needs to devote most of its energies, expertise and time. Quality of final product largely depends upon the paddy procured.  Many rice mills avoid to indulge in such a laborious process and purchase semi-processed rice from brokers instead of paddy from farmers. Unfortunately, this cannot be done without compromising on quality.

2. Husking

The selected Basmati paddy is then allowed to slowly reduce its moisture by natural-sun-drying-method, to achieve optimum moisture content for husking. Paddy is spread over large fields during the day and left for drying in the sun. This gradual drying helps to avoid thermal cracks in the rice grains, which would result in broken grains at later stages

3. Warehousing

One of the main peculiarities of Basmati rice is enhancement in its taste and aroma when it is seasoned for eight-to-nine months. IRM has made it part of its policy to sale only seasoned rice for consumption by its customers.

During the period stocks remain in warehouses, these are subjected to regular inspection and fumigation from time-to-time against infestations by organisms.

4. Cleaning

Milling starts with the cleaning of rice. This is a multi-step process where foreign material like straws, mud balls, threads, stones, paddy and metal particles are removed from the rice.

High performance precleaners and classifiers are used to achieve great accuracy in feeding a purified rice to the later processes. This process is applicable to both the white rice and brown rice.

5. Whitening

Rice is a delicate grain; requires extra care in processing. Any rough handling during processing can cause the grains to break or develop cracks. At IRM's plant rice is gently milled in whitening machines in several passes to ensure efficient removal of bran. Number of passes depends upon the degree of whiteness required

Furthermore, rice is allowed to pass through mist polishers which impart an extremely clean and glossy white appearance to the kernels, a distinct advantage over traditional milling methods

6. Length & Width Grading

IRM performs both thickness and length grading. Through this process broken and shriveled rice is separated from head rice to a very high percentage of accuracy.

7. Colour Sortex

The final step in rice processing is color sorting. This is aimed at to remove discolored grains from processed rice to give the final product a uniform-color look.

IRM uses Sortex90004, provided by Sortex of London, that is the latest version in this highly acclaimed series of color sorters.

Color sorting is an intricate computer-controlled process where CCD technology is used for performing high-resolution-optical inspection of each and every kernel. It removes the high concentration of predominantly chalky and discolored kernels to give final product a uniform appearance.

7. Packing

IRM has the most modern electronic bagging scales that ensure high degree of accuracy in weighing. It is therefore that each and every bag shipped by IRM weighs as per ordered quantity. This equipment is capable of packing in different sizes ranging from 1Kg to 50Kg. Several kinds of packing materials are used as per customer demands, such as:-

i)   Cardboard / Paper-sack
ii)  Polypropylene
iii) Cotton
iv) Jute
