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 dat a acquisition system. The results showed that the drying rate has a direct relationship to temperature. https://www.marcelovicente.com/product-category/hydrate-shampoo/
