Design and Fabrication of Automatic Roti maker

Project Title

Design and Fabrication of Automatic Roti maker

Project Area of Specialization RoboticsProject Summary

RotiMAK is the Final Year Student Project of Mechanical Engineering Student of Mehran University of Engineering and Technology Jamshoro.

The automatic roti machine that we are going to develop is named as RotiMAK. This machine will be fully automated. There are many parts and sections of this machine that we are going to add to this machine.

The first and the most complex part of RotiMAK is dough making. The dough making process is the very first step in any kind of roti making process. For the dough making we need the proper ratio of ingredients; Water, oil and wheat flour. For the proper flow of these ingredients, we are using an advanced hopper mechanism, for proper flow of flour, water, and oil we use the stepper motor with a proper time delay with computer programming.

Then the second step is to flow the developed dough to the heating source; an electric pan for that an ejection system is to be installed at the dough making process. Also, that dough ejection can be done by a stepper motor.

The third step is to design the heating area where roti must bake at a high temperature of about 230-250 o C. The temperature of that pan is also controlled. At the same place where roti will be baked. The flat press mechanism will be installed that will press the ball of dough to prepare the perfect and plan round roti. The designed value for the roti making process id 1 MPM (meal per minute).

There are many processes that will occur simultaneously, and this will be done by high-quality algorithms and programming. This totally depends upon Artificial Intelligence.

This machine is designed in order to facilitate mothers, sisters, and housewives.  The rotis are still mostly baked by conventional methods and it took longer for our mothers, wives, and sisters to bake roti for the whole family. In order to reduce human efforts, we are interested to work for the betterment of society and want to develop a machine that bakes roti automatically.

It is a machine that will run on electricity. This machine performs all the process by itself from dough making to the baking of Chapati, there are four processes on which this machine will work that are; dough making, rolling dough, pressing the dough and baking Chapati.

Project Objectives

The purpose of this machine is to reduce human efforts and to reduce the workload of mothers, wives, working women. The main objectives are mentioned below;

Object 1. To design and fabricate automatic roti-maker

Object 2. To develop an algorithm to perform all the action automatically

Object 3. Reduce human efforts to cook the meal

Object 4. Save time for cooking

Project Implementation Method

• Dough Making

The very first and difficult part of the project dough making process. It needs a proper proportion of ingredients for making a perfect ball of dough for the baking of roti. The dough making process is to do within a small container, where the predefined amount of ingredients (water, oil, and flour) mixed together by rotor run by a motor. An algorithm is set for the proper time delay for the running of the motor to make a dough. When the dough is ready an ejection mechanism is installed that ejects the dough for further process. 

• Flat press mechanism

When the dough is ready and shifted for baking, before heating it a flat press mechanism is installed that flatten the round ball of dough. In the proper dimension of roti and then heating is provided to bake the roti.

• Heating/backing

The main part of roti making is project is heating elements and heating process. The controlled heating system is used to bake the roti. The baking temperature is ranged from 230 to 250 centigrade. The flat press mechanism presses the dough in two steps in order properly puff the roti and in proper dimensions, then puffed roti is ejected.

• Control system

This is fully automated machine uses a highly precise and accurate control system to perform the actions from dough making process to completely puffed roti. For the control system, it uses a 32-bit microcontroller and more than 15 sensors that provide the feedback at every measurable point. And the algorithms are designed in python language.

Benefits of the Project

• The main motive of RotiMAK is to reduce human efforts and time.
• RotiMAK is the robotics kitchen appliance that automates the entire process of roti making. All you need do is to touch a button, and RotiMAK will do everything else to make a fresh puffed Rotis within few seconds.
• We can make a wide variety of flatbreads with the RotiMAK.
• We can make Rotis, flatbreads and much more. It’s up to the limits of our own imagination.
• One hour of an electric RotiMAK consumes just little over one unit of electricity.
• RotiMAK can make as many rotis as you like nonstop. However, you need to top up the ingredients every 12 to 14 Rotis.
• Cleaning is mess-free since it is washable dish wear.
• It works on a flat pressing mechanism where a perfect round roti comes out in an instant.
• RotiMAK uses very little oil and even we can decide how much should go in which make the roti quite healthy.
• RotiMAK has a fine particle dispensing mechanism for home use as the floor is in powder.
• It has an adaptive system which makes real-time computation to mirror the human judgment to make perfect dough balls every time.

Technical Details of Final Deliverable

• A Final Prototype of automatic roti maker machine.
• A complete software integrated hardware machine.
• A Final and complete report of Machine includes software algorithms, integrated control system results, proper and detailed defined mechanism used in the projects i.e. ejection mechanism, kneading mechanism of dough making, flat press mechanism and heating mechanism.
• A complete and properly puffed roti.
• The capacity of an automatic roti maker is one meal per minute (MPM).
