Design Of Injera Processing Machine

The present work emphasis in asserting a solution to the laborious Injera making system whichrnare faced by most of the communities in and around Ethiopia. The main downside of the presentrnexisting Injera making processes is the source of power and energy consumption, tedious laborrnwith little or no hygiene control and the production efficiency, which is predominantly becausernof the use of electric source or conventional fire wood for mitad and unskilled labors. rnThe proposed machines have been achieved by integrating the dough preparation and thernbaking operations to work simultaneously for continuous Injera production. The dough isrnprepared in a mixer container which are connected to a baking conveyor unto which the precisernquantity of dough is squeezed on to the baking chamber through the conveyor. The bakingrnconveyor are controlled to operate in-steps with controlled speed and appropriate delay forrninjera to bake, which is achieved by using a stepper motor with a control unit. The componentrndesign and the assembly has been done by CATIA and the real time simulation has beenrnperformed by ANSYS. rnThis machine is highly recommended to save energy, minimize individual energy bill perrnmonth and minimize operation costs of hotels and restaurants. Therefore, this injera bakingrnmachine saves labor, energy and it is hygienic.
