Perdas em diferentes plataformas na colheita da cultura da mamona (Ricinus communis L.)

Abstract

Castor bean (Ricinus communis L.) is an oilseed plant from the Euphorbiaceae family, which is not one of the most cultivated crops in Brazil and the world, however, with the advancement of studies, it began to be observed that it has great potential in its oil derived from its seed, as it adapts to different types of soil, is tolerant to periods of drought and does not have a high nutritional requirement. Its oil has great potential for use in the oleochemical industry, the plant has a very high oil content ranging from 48 to 60% in the seed. The purpose of the study is to identify the points of grain loss during the mechanized harvesting of castor beans and evaluate the quality of the grain in the harvester's bulk container. As the results of the 2017, 2019 and 2020 platforms were analyzed, the 2020 model demonstrated lower total grain losses. However, there is room for improvements in all platform models, especially with regard to manufacturing processes, machining, gap control and standardization of distances between parts. These optimizations have the potential to further increase the performance and efficiency of harvesting platforms
