Abstract

Abstract

A drying kiln schedules is a prescript, for every each species and thickness, of environmental conditions inside drying chamber, which equilibrate the drying rates and formation defects. Among the methodologies of drying kiln schedules elaboration, those based on application of empiric equations having the specific gravity as independent variable and those based on evaluation of small pieces during drastic drying are highlighted. The objective of this research was to apply and to compare these two methodologies for drying kiln schedules elaboration for marupá, pará-pará and virola. The parameters for drying schedules elaboration were experimentally obtained on 32, 32 and 29 pieces of marupá, pará-pará and virola, respectively. Comparing the drying potential obtained by different methods, it was different at all steps for all species, and the dry bulb temperature is different until the moisture content of 30% for marupá and virola and under this point for pará-pará.

Keywords: Conventional drying; tropical woods; specific gravity.
