This thesis is the design and development of semi-automated food chopper focused on
improving efficiency when it comes to food processing preparation that can be used by crop

farmers using partial automation that minimizes manual labors. The system features a dual-
operation mechanism, allowing users to alternate between manual and automated functions via a

built-in trap door. The prototype was assessed against traditional manual methods, with a focus
on efficiency, safety, and user convenience. Key components include a motor-powered blade,
food hopper, output tray, manual trap door, and a push-button control interface. Testing showed
the device effectively handles softer foods but is less efficient with tougher inputs. User feedback
highlighted its simplicity, portability, and suitability for light-duty tasks, though the manual
mode-switching was inconvenient. Recommended improvements include enhancing motor
power, refining the blade, and adding safety features. Overall, the Semi-Automated Food
Chopper shows potential as an affordable, practical tool for domestic kitchens and small-scale
food processing.
