Award : Class 9th - 10th
Award Function : IGNITE 2015 Awards
Award Year : 2015
Sourav has created a machine that peels lac from branches of trees and plants through pressure system. The conventional process for lac extraction is to cut the lac-coated branches of host trees, crush and sieve the lac to remove impurities. The machine made by Sourav can remove lac from the branches without breaking them. As a result, the amount of impurities is lesser in the extracted lac and it takes lesser effort to clean it. The machine is attached with a rotator and works on the principle of a sugar cane juice extracting machine.
The idea occurred to Souravwhen his father asked him to remove some unwanted grass and plants surrounding their house. While removing the plants,he saw that there was lac (the resinous secretion of lac insects). When he tried removing it by hand, he realized that the lac was running till the roots of the plants. He then thought of a machine that could easily remove lac from plants and trees but did not have a reference.
That is when he spotted a sugarcane juice extracting machine and decided to work on his lac processing machine based on that model. He collected some raw materials— mainly scraps of automobile parts— and started work on his project.
“Lac is very expensive and used by many industries. Till now, people in my village used to remove lac with their hands. That is why I thought of a lac processing machine, which will make the process easy, without wasting lac. I discussed the project with myscience teacher, Amod Kumar, and sought funding for the project from my father. My friends helped me collect raw material to make the machine,” says Sourav, whose favourite subject is physics.
At present, Sourav is pursuing a diploma in electrical engineering from KIIT University, Bhubaneswar after which he aims for a degree inBachelor ofTechnology. “I want to become an electrical engineer like my father, who works with the Jharkhand State Electricity Board. My mother, who is a homemaker, is my role model and supports me in everything I do,” says Sourav. His sister is pursuing a medical degree from Bhubaneswar at present.
