Introduction

I. INTRODUCTION

The bakery industry has long been characterized by following traditional methods and relying on old techniques passed down from generation to generation. However, the baking landscape has changed in recent years as technology has been integrated into traditional processes. This change opened the way to innovative solutions aimed at improving the efficiency, uniformity and quality of confectionery production. In this context, the focus of this research is the design and manufacture of an advanced cupcake baking system that uses technology to simplify and optimize the baking process. The system represents a fusion of simple technology and traditional baking methods and offers a usable solution for hobbyists as well as professional pastry chefs. The heating system is an MS frame where the heating coil is placed at the top in a box shaped frame through which the cupcakes get baked for 7 minutes and exit the box once baking is completed. The system utilizes a conveyor system to transport the cupcakes from initial position to the heating phase where a heating coil is placed for the baking process of the cupcake to begin, once the baking phase completes, the cupcakes are transported out of the heating phase and successfully dispensed onto a plate, ready for serving. We switch on the coil to start the preheating process which takes 10 min and then the cupcake batter is filled in a silicon mould and the mould is placed on a thin rectangular plate which is welded to the conveyor and the conveyor starts moving once the machine is switched on. The entire process runs with the help of an Arduino microcontroller responsible for the automatic movement and accurate delay provided where necessary to complete 1 cycle. Each cycle comprises of 3 cupcakes being baked simultaneously and once dispensed it returns to the initial position for the next batch cycle to begin. Along with the insulation done with ceramic fiber and asbestos rope, the baking of the 3 cupcakes after multiple test runs takes approx. 7 minutes as a result.
