1. Development of PLC Based Automated Virtual Cooking Machine A Thesis by Md Nayeem Hossain Supervised by Dr. Sandor Misak Department of Electrical Engineering University of Debrecen
2. Introduction • Cooking • Automatic Machine • PLC 2/17
3. Problem Statement Repetitive Job Time Consuming Tiring Inconsistent Test Cooking 3/17
4. Market Research Robotic Kitchen (2018) Commercial kitchen Spyce Kitchen (2016) Commercial kitchen Cooki (2015) Ingredients requires preprocessing One Cook (2017) Works only with prepacked meal tray by the company Steam Oven (2017) Works only with prepacked meal by the company Available Products Expensive!!! 4/17
5. Requirements It will perform automatic cooking. Time Efficient Store the recipes. It will make specific dish as instruction Taste will be repeated as per requirement. Will save the human energy for more productive tasks. 5/17

13. TESTING ENVIRONMENT Block Diagram Testing Board Stepper Motor Operation Nema 17 13/17
14. Results 14/17 • Compilation • Program Flow • Input conditions • LEDs indication • Visualization Simulation • Communication • Visualization • Web-visualization • Stepper motor • Indicators Testing
15. Improvement Possibilities 15/17 1. Number of Recipes 2. Container Increment 3. Implementation of Feedback systems 4. VFD Integration for speed control 5. Integration of HMI
16. Conclusion Market research was done to find out the available cooking machines. All the parts and the operation of the cooking machine were described. All electrical parts were selected and presented in the book. PLC IO list was created as per the requirement of the operation description. Electrical diagrams required by the project were designed. The main control program was developed in SE Ecostruxure Machine Expert software. The web-visualization was implemented. The test environment was designed, and the operation of the virtual machine was tested. 16/17
