JOURNEY OF RICEPADDY TO PARBOILED RICE

•Rice is one of the important food of today's world.•Estimated , half of the world’s population take on rice as their main food.•In Asian continent about 67% of the rice is produced.•After China, India is the 2nd largest rice consuming country in world.•As rice is important part of our daily meal, I want to put some light on the processing of rice parboiling.

IMPORTANT FACTS

PADDY PARBOILING▪ Rice parboiling is a pre milling process.▪ Parboiling makes rice easier to process by hand, boosts its

nutritional profile and changes its texture.▪ Parboiling of paddy is a hydrothermal process in which there is

gelatinization of starch.▪ The process of parboiling is carried out in three main steps: 1. Soaking 2. Steaming 3. Drying

PROCESS OF PADDY TO PARBOILED RICE

❑ Paddy selection❑ Paddy cleaning❑ Soaking❑ Steaming❑ Drying❑ Milling❑ Whitening❑ Grading

SEQUENCED PROCESS ➢ Paddy Selection: In this process paddy is selected and

examined and the finest paddy is selected.➢ Paddy Cleaning: Paddy cleaners remove impurities such

as straw, dirt and debris. Unhealthy and immature grains are also blown off during paddy cleaning.

➢ Soaking: The paddy is soaked in the huge water-filled vessels for a specific time & temperature for a specific variety of rice.

➢ Steaming: The soaked paddy is then transferred to the steaming vessels where it is kept at a certain temperature for a short time.

✕ Drying: This process is mainly carried out in two ways: 1. Paddy is dried in pre dryer. 2. Paddy is shifted to column dryer for further reductions Nowadays smoke free hot air generated through steam heat exchangers is used

to dry the paddy.

➢ Milling: In this process husk is removed.➢ Whitening: Two different types of machines are used for

whitening of rice. 1. Emery-wheel 2. Cast –rotor

Both of these machines remove bran layers of rice grains.➢ Grading: Broken, smaller and shriveled grains are separated

from the head rice by using Plan Sifters, large Graders.
