Resumo: To evaluate the effect of temperature and air velocity on drying rate, slash pine wood pieces of 25 x 125 x 750 mm were dried in semi-industrial kiln with forced convection. The process was conduct for two temperatures and two air velocities and controlled by a data acquisition system. The results showed that the drying rate has a direct relationship to temperature, air velocity and wood moisture content. Through multiple regression analysis it was possible to detect statistically significant effect of temperature and air velocity on drying rate and drying time, at 99% confidence level. Since the influence of air velocity on wood drying decreases with moisture content, because of economic reasons, more investigations were suggested about the relationship between the two variables during falling-rate drying period.

O processo foi conduzido para duas temperaturas e duas velocidades de ar e controlado por meio de um sistema computadorizado. Os resultados mostraram que a taxa de secagem tem uma relação diretamente proporcional com a temperatura, velocidade do ar e umidade da madeira. Por meio da análise de regressão múltipla detectou-se efeito estatisticamente significativo da temperatura e da velocidade do ar sobre a taxa e o tempo de secagem, com um nível de confiança de 99%. Como a importância da velocidade do ar na secagem decresce com a diminuição do teor de umidade, sugere-se, por razões de economia, mais investigações acerca das relações entre as duas variáveis durante o período de taxa de secagem decrescente.Universidade Federal de Santa Maria2005-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/168410.5902/198050981684Ciência Florestal; Vol. 12 No. 2 (2002); 99-106Ciência Florestal; v. 12 n. 2 (2002); 99-1061980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1684/960Santini, Elio JoséHaselein, Clóvis Robertoinfo:eu-repo/semantics/openAccess2017-06-05T13:08:43Zoai:ojs.pkp.sfu.ca:article/1684Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-05T13:08:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
