Design of Automatic Multipurpose
Indian Flatbread Maker

Abstract Roti is an irreplaceable component of the Indian menu. But the process of
roti making is quite tiresome and time consuming. Whether it is a family gathering
like weddings or hostel mess, often a problem arises regarding demand and supply
of freshly baked roti. There are machines available in the market which can make
this task easy for us, but they have certain shortcomings such as expensiveness,
lack of quality, lack of taste, extreme low or extreme high rate of production of roti
and imbalance between these factors. The main aim was to design and fabricate an
efficient, compact, and user-friendly automatic roti machine to serve the needs of
people. Also for not alternating the traditional taste, we used LPG flame burners
to cook it. This paper describes the design and fabrication of the machine. Each of
its modified components is explained and supported by a mathematical calculation
and the reason behind its selection/designing. The stress analysis and other technical
aspects are also taken into consideration. The cost of the whole project was under
Rs. 50,000 and is capable of producing 480 rotis/h. It requires electricity to preheat
the dough using G coil. Majority of parts are made up of mild steel and cast iron.
Cam follower mechanism is used to flatten the dough balls followed by conveyor
mechanism for baking. Whole machine is powered by 1.5 Hp motor attached to 80:1
gearbox.

Wheat is one of the most commonly available daily staple in India and all over the
world. Its demand has been increased in recent years due to the abundant health
benefits provided. The research has shown us that wheat helps us with reducing
the heart rate and treating gallstone, asthma, skin, and cancer diseases due to its
