An Appropriation Factor of Cassava Single Tuber Peeling Machine for Cassava Chip
Keywords:
Cassava, Peeling, KnifeAbstract
The peeling of cassava roots is an important step in cassava chip processing. Hand or manual peeling is commonly used, but it is slow and lacks sufficient capacity for efficient production. This research aims to design and fabricate a single tuber peeling machine prototype for producing crispy cassava chips. This peeling machine comprises: (1) a structure, (2) power unit, (3) transmission unit, and (4) a set of peeling knives. The experimental conditions were studied at peeling knife speeds of 90, 100, and 110 rpm, using three different degrees of blade and three levels of blade length. The results revealed that the most suitable conditions were a speed of 110 rpm for the peeling knife, using an angle of 20 degrees from the axis and a blade length of 15 mm. These conditions provided 95.09% peeling efficiency, 2.22% texture loss, and a machine capacity of 94.43 kg/h, which was 2.5 times faster than the traditional method (human labour).
