Resumo: | The cowpea has taken up a lot of space in Brazil's grain production, thus, the need arises to classify it as to its mechanical properties, because during all the processing and storage of the grain, it can suffer different types of pressure that cause cracks and breaks in the grain, therefore, this study aimed to determine the influence of water content on the values of maximum compression force for fixed deformations and to determine the proportional modulus of grain deformity of cowpea cultivars submitted to compression. Were used grains from two bean cultivars, Novaera and Tumucumaque in the water content of (0.12; 0.15; 0.18; 0.20 and 0.23 decimal b.s.), the work was carried out in a completely randomized design, where for each water content, 10 deformations were applied (0.02; 0.04; 0.06; 0.08; 0.10; 0.12; 0.14; 0.16; 0.18 and 0.20 mm). Soon after the compressive strength was analyzed with the aid of a universal testing machine of model test, then the proportional deformity module was determined, with the deformation values evaluated, the hardness and elasticity values of the cowpea grains were established as a function of the water content. The compression force required to deform the cowpea decreases with increasing water content, between 2 and 105 N for the cultivar Tumucumaque and between 2 and 97 N for the cultivar Novaera. The proportional deformity module increases with the reduction of the water content and the product deformation, obtaining values, for the studied humidity range, between 4.9 x 107 to 31.9 x 107 Pa for the cultivar Tumucumaque and of 5.9 x 107 to 42 x 107 Pa for the Novaera cultivar. |

Mechanical properties of cowpea beans at different moisture contentsCompression Deformation Proportional deformation modulusThe cowpea has taken up a lot of space in Brazil's grain production, thus, the need arises to classify it as to its mechanical properties, because during all the processing and storage of the grain, it can suffer different types of pressure that cause cracks and breaks in the grain, therefore, this study aimed to determine the influence of water content on the values of maximum compression force for fixed deformations and to determine the proportional modulus of grain deformity of cowpea cultivars submitted to compression.

The compression force required to deform the cowpea decreases with increasing water content, between 2 and 105 N for the cultivar Tumucumaque and between 2 and 97 N for the cultivar Novaera. The proportional deformity module increases with the reduction of the water content and the product deformation, obtaining values, for the studied humidity range, between 4.9 x 107 to 31.9 x 107 Pa for the cultivar Tumucumaque and of 5.9 x 107 to 42 x 107 Pa for the Novaera cultivar.Cowpea production has gained considerable ground in Brazil. Cowpea grain undergo different types of pressure and may crack and break during processing and storage, thus, there is a need to classify the mechanical properties of the beans. Therefore, this study aimed to evaluate the influence of the moisture content of cowpea beans on the maximum compressive force for fixed deformation and determine the proportional modulus of deformity under compression. The cowpea cultivars Novaera and Tumucumaque were evaluated at different moisture contents (0.12; 0.15; 0.18; 0.20; and 0.23 decimal d.b.). The experiment was arranged in completely randomized design for each moisture content and 10 deformation rates were applied (0.02; 0.04; 0.06; 0.08; 0.10; 0.12; 0.14; 0.16; 0.18; and 0.20 mm). The compression force was assessed using a universal testing machine and the proportional deformation modulus was determined. Following, hardness and elasticity of cowpea beans ??as a function of the moisture content were established. The compressive force required to deform cowpea beans decreases with increasing moisture content: between 2 and 105 N (Tumucumaque) and between 2 to 97 N (Novaera). The proportional deformation modulus of cowpea increased as the moisture content and deformation reduced, ranging from 4.9 x 107 to 31.9 x 107 Pa (Tumucumaque) and from 5.9 x 107 to 42 x 107 Pa (Novaera).Universidade Federal de Viçosa - UFV2021-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/1093110.13083/reveng.v29i1.10931Engineering in Agriculture; Vol. 29 No. Contínua (2021); 58-65Revista Engenharia na Agricultura - REVENG; v. 29 n.
