The Culture of crambe became promising since its grains presents high oil content. The methods of drying may influence the quality of crude oil extracted from the beans, depending on the way it is managed. This study goal was to evaluate the influence of different drying methods on the quality of the crude oil extracted from crambe grain. The experimental design was completely randomized with five treatments (drying with heated air, natural air, yard, shade, and at the field), and with four tests for each. In order to check the quality of the grains, we performed an analysis of fat acidity, and to evaluate the crude oil quality, we conducted analysis of iodine value, acid value, water content, density at 20ºC, and a kinematic viscosity at 40°. After obtaining the data, the results were submitted to analysis of variance. When significant means were detected, they were compared by t-test (p ≤ 0.05). The method of drying with heated air provided a lower rate of fatty acid in grains. The drying methods evaluated did not compromise the quality of the oil extracted from the crambe grain.
