“…The first operation in the process-ing of cassava for human consumption is the removal of the cassava peels. Osei (2020) stated that cassava peeling in the olden days was done by the use of stones and wooden flint before evolving to the simple household knife. Several problems are encountered during indigenous processing which has created an urgent need for mechanization and upgrading of processing (FAO, 2015).…”

“…Traditionally, cassava peeling is known to be done manually by slitting along the length of the cassava with a sharp object and removing the peels with the help of the hands. The manual approach of peeling cassava has been characterized by drudgery, high rate of injury and also places a limit on the peeling speed (Diop and Calverley, 1998;Osei, 2020). Regardless, this method is preferred by local processors and small-scale farmers because they believe it yields the best of results and it is the only method available to them.…”

Cassava peeling machines are available but are inaccessible and prohibitively expensive, especially for small-scale processors to acquire. This paper examines the perception and willingness of smallholder cassava processors to pay for cassava peeling machine services using data from 300 cassava processors in the Bono East Region of Ghana. A perception index from a 5-point Likert Scale and Cragg’s Double Hurdle model were the methods of analysis. The results revealed a perception index of 2.54 and this implies that cassava processors have neutral perception about the cassava peeling machine service. Also, it was found that majority of the processors (75.33%) are not aware of existence of the cassava peeling machine. In addition, we find that 99.63% of the cassava processors are willing to patronize the services of the cassava peeling machine. Moreover, cassava processors are willing to pay an average amount of GH₵ 4.21 for a 50 kg bag of cassava peeled using the services of the cassava peeling machine. Furthermore, the study revealed that factors such as educational level, quantity produced per processing cycle and the dependence on cassava processing as the main source of income positively and significantly influenced willingness to pay for the services. Finally, the amount processors were willing to pay was influenced by educational level, household size, source of income, perception about machine’s complications and group membership. The study recommends that investors consider installing cassava peeling machines to provide commercial cassava peeling services in processing areas. While generating income to investors, it will contribute to reducing postharvest losses during cassava processing. Future efforts should focus on raising awareness about the availability and benefits of commercialization of mechanized peeling of cassava.

“…From the results, it was observed that the mechanical properties are closely associated and directly proportional to the moisture content of the tubers. Cassava tubers have a high moisture content, which reduces hardness, shear force, and cutting force (Kolawole, Agbetoye, & Ogunlowo, 2007;Seth, 2020). The maximum force (N) required for rupturing in cassava flesh and shearing in peelings were 410.39 ± 40.15 N and 185.37 ± 14.65 N, respectively.…”

“…Among the different unit operations carried out in cassava processing, mechanization of peeling followed by slicing and rasping operation are highly crucial (Sajeev, Sreekumar, Unnikrishnan, Moorthy, & Shanavas, 2010). Peeling is the primary unit operation, which is difficult and possesses the greatest bottleneck in the processing of cassava tubers for either edible or industrial purposes (Fadeyibi & Olusola Faith, 2020;Seth, 2020). On a fresh mass basis, cassava peelings constitute about 10-15% of the total mass of tubers (Aro, Aletor, Tewe, & Agbede, 2010;Baiden, Rhule, Otsyina, Sottie, & Ameleke, 2007;Lukuyu, Okike, Duncan, Beveridge, & Blummel, 2014;Pooja, Sajeev, Jeeva, & Padmaja, 2018).…”

“…The presently available cassava peelers are batch type and mainly working in the principle of impact and abrasive action (Akintunde, Oyawale, & Tunde-Akintunde, 2005;Egbeocha, Asoegwu, & Okereke, 2016;Fadeyibi & Olusola Faith, 2020;Kamal & Oyelade, 2010;Oluwole & Adio, 2013). The main disadvantages of the batch type mechanical abrasive cassava peeler are severe mechanical damage, un-even peeling, flesh loss, and low peeling efficiency with increased time of operation (Adetan, Adekoya, & Aluko, 2003, Jimoh, Olukunle, & Manuwa, 2014;Olukunle, 2005;Seth, 2020). The major challenges in the development of continuous shearing type cassava peeler for small-scale processing are due to the irregularity of cassava tubers, which vary in size, mass, and shape according to the cultivars.…”

The data on physical and mechanical properties of short and long-duration cassava cultivars are limited to design an efficient continuous type peeling machine for smallscale processing. Short duration cultivars included Sree Jaya, Sree Vijaya, and Sree Swarna, as well as long duration cultivars included M-4, Sree Athulya, Sree Suvarna, H-226, Sree Raksha, Sree Pavithra, and Sree Vishakam, were investigated. The moisture content, girth, proximal diameter, middle diameter, cylindricity, and tuber surface taper angle were the highest for long-duration cultivar H-226. The maximum length was observed in the short-duration cultivar Sree Swarna. The periderm thickness was the highest for Sree Suvarna, whereas the highest proximal cortex thickness, middle cortex thickness, and distal cortex thickness were observed in Sree Athulya, Sree Vijaya, and M-4 cultivar, respectively. The highest bulk density, true density, and porosity were observed in the long-duration cultivars; Sree Raksha, Sree Athulya, and Sree Suvarna, respectively. The highest hardness, shear force, and rupture force were recorded for cassava peelings in the cultivar Sree Athulya. Similarly for cassava flesh, the highest hardness, shear force, and rupture forces were recorded in the Sree Suvarna cultivar. A strong positive correlation for true density with bulk density and proximal diameter and moisture content with cylindricity and middle-end diameter was found from the multivariate correlation analysis. Statistical analysis showed that the reported physical and mechanical properties of the cultivars were highly significant (p <.01). Practical ApplicationsEngineering properties such as physical and mechanical properties are important for designing machines, storage structures, and processes. Cassava tuber peeling by the manual method is time-consuming, labor-intensive, and has a low capacity. Thus, the
