A prototype of roti roaster

Guwahati: Born and brought up in number 1 Morisuti village in flood-prone Lakhimpur district of Assam, Dhrubajyoti Kakati, 21, has seen the problems faced by his neighbours and those in the relief camps in preparing food during floods that wreak havoc almost every year.

Moved by their plight, Kakati, a third semester student of agriculture science in Biswanath College, has invented a hand-held roti roaster which can heat roti from an open heat source without burning it.

"It can be used to roast a roti directly over a direct heat source such as a stove, heater, burning coal or wood in the final stages of roti-making process. By using this device, one can easily and safely roast both sides of a chapatti over a direct heat source without the need for tossing it or touching the direct heat source. This will not burn the chapati which happens normally," Kakati said in his recent application seeking a patent.

He is now awaiting the patent before going for further modification and production for commercial purposes.

"This can be useful in relief camps during floods or in trekking expeditions. Restaurants and hotels can also use this. They can also use it to roast meat," he said.

"The partially-cooked chapati is heated directly using a hand-held wire mesh or placed directly on the heat source. Normally, the puffed-up chapati has to be flipped over," he said.

Kakati used stainless steel to make the device. Inspired by Uddhab Bharali, whose inventions have helped farmers, physically-challenged and different sections, Kakati's school science model highlighting impact of floods on soil was selected for National Children Science Congress at Jaipur in 2011. He made a pedal-operated brick-making machine, a solar power-operated umbrella, a pedal-operated grinder and a multi-purpose crutch but those did not get patents. "My patent application was published in the official journal of the patent office in May and I hope I will get it this time," he said.
