This paper presents differences in the drying behavior of red oak and yellow-poplar sapwood, heartwood, bark their relationship with selected physical characteristics. Drying experiments were performed on samples respective species at 105 °C under nitrogen conditions. In addition, characteristics such as green moisture content, specific gravity, volumetric shrinkage, shrinkage cell wall, total ...

This paper presents an experimental evaluation of the first commercial scale dry-sort-redry (DSRD) strategy for drying of 2x4 Pacific coast hemlock (PCH) lumber. The DSRD strategy is a methodology designed to reduce final moisture content variability in kiln dried lumber by complementing conventional drying with radio frequency vacuum (RFV) drying technology. The strategy’s objective is to avoi...

"Observer based model predictive control of the water Based painting drying using a humidity profile soft sensor and a temperature measurement", This paper deals with the model predictive control of an infrared drying process of a water based epoxy-amine painting. During the drying cycle, the control problem is to optimize the use of the process under constraints. This approach is based on a no...

introduction: one of the most important aspects of food preservation is controlling the moisture of material such as fruits.dryingis considered as important method to controlbacteriasafely using reduction of moisture. the hot air drying method has been widely adopted in manufacturing of conventional dried food.nowadays, infrared radiation (ir) has significant advantages over conventional drying...

Concrete shrinkage and creep under variable hydric conditions are important factors for the safety durability of concrete especially in nuclear reactor or waste storage background. A large (and long – more than 900 days) experimental campaign, conducted on two different concretes, has therefore been designed to study strains non loaded concretes submitted drying liquid water imbibition cycles. ...

Abstract Understanding how the evolving molecular composition of an oil paint layer on its transition to aged solid film affects dimensional change and mechanical properties is fundamental assessment material durability more broadly risk degradation paintings. Tensile properties—modulus elasticity strain at break—as well as cumulative shrinkage were determined for a selection paints from Meckle...

Coating shrinkage upon drying is a phenomenon well known to the paper coating industry where it often causes changes in the final structure of the coating layer, leading to poor results in terms of gloss, light scattering, surface strength, coverage and printability. The aim of this paper is to improve the understanding of coating shrinkage by measuring the forces related to the capillarity, ac...
