Umidade de colheita, métodos de secagem e tempo de armazenamento na qualidade tecnológica de grãos de trigo (cv. 'Embrapa 16')

Abstract

The objective of this research was to study the harvest moisture and drying method systems as a function to storage period on the conservability and technological quality of wheat. Grains of wheat (Triticum aestivum L), cultivar 'Embrapa 16', produced in the Granja Bretanhas, in Jaguarão, RS, agricultural harvest of 1997/1998 were harvested dry in the plant (14% of moisture), with 16 and 18% of moisture. The samples harvested with moisture of 16 and 18% were submitted to artificial drying by intermittent method, with air at 70°C, stationary, with air at 45°C; and stationary, at room temperature. The grains were stored in a conventional system, during 12 months, with the realization of evaluations at 4 month intervals. Wheat grains harvested dry shown inferior technological quality and conservability in storage as compared to harvested with moisture above 14% and dry at artificial dryer.
