Análise das estruturas de secagem de arroz no município de Alegrete

Abstract

The drying of grains is one of the main stages of postharvest to maintain the conservation of stored grains. However, daily errors occur during drying which cause the loss of grains that are fundamental for human survival, or the loss of seeds. At present, drying structures are arranged as follows: pre-cleaning and drying of grains in intermittent or continuous dryers. The present work has the objective of analyzing the state of conservation and functioning of the dryers, through the sampling methods, determination of the entrance and exit humidity of the grains, flow and temperature of the air in the drying, types of fans, states of conservation of the dryers and the types of dryers used in the city. It was concluded that the evaluated drying units at Alegrete satisfy the minimum requirements to obtain a good drying and grain quality and yield.
