Optimizing radiata pine drying schedules

Wood Material Science and Engineering, 2011
Abstract In an era of increased energy costs and concern about profitability, using the best drying schedule is important for softwood drying. The first part of this study looked at the feasibility of finding the combination of dry bulb, wet bulb and air velocity that either minimizes overall drying cost or maximizes profit in a simple radiata pine ...

Drying Schedules for Canelo Wood

Drying Technology, 2013
Canelo wood is a highly valued native species in Chile that shows delicate marbling patterns with a pinkish soft silver luster. Due to its decorative qualities, canelo wood is dried for the manufacture of furniture and musical instruments. However, canelo wood lacks vessels cells that typically transport the water in hardwoods. Per its drying behavior,

Probabilistic Analysis of Timber Drying Schedules

Drying Technology, 2003
Abstract Timber drying schedules are primarily chosen to achieve a certain final moisture content accompanied by a minimum amount of board degrade. However the schedule adopted also influences the dispersion in moisture content between boards at the end of drying.

Assessment of Timber Drying Schedules by Evaluation of Damage Risks

Drying Technology, 1993
ABSTRACT The macroscopic description of drying kinetics and the estimation of the corresponding moisture profiles are coupled by a simple diffusion model. This model describes correctly the drying of a board in a kiln, using a constant mass-transfer coffeicient associated with the drying stage under consideration.

A Simulation Tool for the Optimization of Lumber Drying Schedules

Drying Technology, 2004
Abstract A two-dimensional wood drying model based on the water potential concept is used to simulate the convection batch drying of lumber at conventional temperature. The model computes the average drying curve, the internal temperature and moisture content profiles, and the maximum effective moisture content gradient through board thickness. Various

Impact of High-Temperature Schedules on Drying of Spruce and Pine

Drying Technology, 2008
The impact of high-temperature drying (HTD) for spruce and pine lumber of 5 × 10 × 244 cm was investigated in this study. Four drying schedules with dry-bulb temperatures from 60 to 110°C were evaluated including Control 1 (conservative), Control 2 (accelerated), HTD1 (104°C) and HTD2 (110°C). In each of HTD1 and HTD2 schedules, two runs were performed,

Integrated scheduling of the drying process in a sawmill

Computers & Chemical Engineering, 2021
Abstract Wood drying is a critical stage in the sawmill production process since it will enable achieving the wood characteristics needed to meet market requirements. Generally, it is a batch process that is carried out in drying kilns that operate in parallel out of phase. Boilers fed with by-products generated in other productive sawmill stages are

Evaluation of drying schedules

AIChE Journal, 1969
AbstractA generalized drying program that can simulate any drying conditions has been solved on a computer. The program includes the variation of humidity, temperature, and wind velocity over drying material. These three variables can be treated as functions of time.

Stacker-reclaimer scheduling in a dry bulk terminal

International Journal of Computer Integrated Manufacturing, 2012
A dry bulk terminal acts as a multi-modal interface for transhipping iron ores. Stacker-reclaimers are the dedicated equipments in storage yard for iron ore handling. Both unloading and loading processes are supported by stacker-reclaimers in most cases. The operation efficiency of dry terminals heavily depends on the productivity of stacker-reclaimers.
