Abstract
Garlic bulb breaking is the unit operation through which cloves are separated to facilitate additional processing. This research work was carried out to design, and manufacture a prototype garlic bulb breaker for a Holeta local garlic variety grown in Ethiopia. The machine consisted of a feed hopper, a garlic separator (two rollers), a fan, outlets for cloves and trash (husk, root, and stem), the main frame, and a drive system. These components and machine assembling were designed using Solidworks software (Version S 2019). The economics of the constructed garlic bulb-breaker such as material and fabrication costs and cost of operation were evaluated with results of 9264.8 ETB and 76.89 ETB/hr, respectively. The cost saved by constructing a garlic bulb breaker over manual garlic bulb breaking by the labor force for planting and processing purposes was 83.42 and 86.63%, respectively. Therefore, the machine could be designed, and constructed for the best cost saved by constructing a garlic bulb breaker over manual garlic bulb breaking.
