Design and Fabrication of Automatic Dosa Maker

Dosa is a traditional food common in South Indian homes. It has been an integral part of South Indian breakfast since ages. Dosa is usually cooked with a non-stick pan and spatula which is time consuming and needs continuous attention of the cook. As the value of time is increasing day by day, especially with the increase in working women, the demand for ready-to-eat traditional food is also increasing. Different prototype developments for Dosa Maker have been conducted widely. Automation plays an important role in the food sector. Automation reduces cycle time, limits human interference hence increasing productivity. The main problem that arises during the design of Dosa maker is to bake both sides of the Dosa automatically. The present work mainly focuses on design, development and fabrication of a fully Automatic Dosa Maker enabled to bake both sides of Dosa without any manual help. A programmed Arduino Mega is used to control the working of the entire system. A servomotor is used here, which helps to flip the Dosa in order to bake both the sides thus enabling to make tasty and hygienic Dosas. The Automatic Dosa Maker is a user friendly and portable machine. As the whole device works on its own it is easy to operate. The whole device runs on electric power. Using electricity as a source of power has less impact on the environment compared to the conventionally used petroleum gas.
