Design and performance evaluation of an enhanced cassava slicing machine

Cassava (Manihot esculenta Crantz) plays a crucial role in the Philippines as a staple food and a key raw material for various industries. Despite its significance, traditional cassava slicing methods remain labor-intensive and inefficient, resulting in inconsistent product quality. This study presents the Design and Performance Evaluation of an Enhanced Cassava Slicing Machine aimed at improving processing efficiency, safety, and product quality. The machine incorporates optimized blade configuration, motor power, and a locally sourced, simple mechanical system. The performance evaluation, conducted with 40 participants, revealed excellent ratings across key operational parameters: capacity, efficiency, speed, and durability, with a grand mean of 4.50 (Excellent). Additionally, user acceptability was highly favorable, with an overall mean of 4.46, indicating strong approval from both technical instructors and local farmers. The findings demonstrate that the enhanced slicing machine improves slicing uniformity, reduces processing time, and minimizes operator fatigue compared to manual methods. This technology-based intervention highlights the potential of localized engineering innovations to improve post-harvest operations, support food security, and enhance rural livelihoods.
