Abstract :

Grain sampling requires the use of appropriate and accurate equipment. This study aimed to compare grain samplers, manual and mechanical, used in the sampling of soybean loads, during their reception by storage units. The used devices were the manual sampler with 1.80 m length and three opening stages, 2.10 m length and three opening stages; and 2.10 m length and one opening stage, besides the mechanical sampler (pneumatic) and the pelican sampler. The analyzed parameters were the contents of impurity, broken grains, pods, immature grains, and moisture. The significance of effect of treatment was determined by F Test and the means were compared by Tukey test (p Key words: classification, grain samplers, impurities, pods A amostragem de graos requer a utilizacao de equipamentos adequados e precisos. Assim, objetivou-se comparar caladores (amostradores) de graos, manual e mecanico, utilizados na amostragem de cargas de soja durante o recebimento em unidades armazenadoras. Os equipamentos utilizados foram os caladores manuais de 1,80 m e tres estagios de abertura, 2,10 m e tres estagios de abertura, 2,10 m e um estagio de abertura, amostrador mecanico (pneumatico) e o calador tipo pelicano. Os parametros analisados foram as percentagens de impurezas, de graos quebrados, percentagens de vagens, graos imaturos e teor de agua. A significancia do efeito dos tratamentos foi determinada pelo Teste F, e as medias comparadas pelo teste Tukey (p Palavras-chave: classificacao, caladores, impurezas, vagens
