Effect of high temperature drying with load on reduction of residual stress and correction of warp of Japanese cedar lumber

Drying Technology, 2022
While sawing logs along the pith to produce lumber, warps would occur in lumber due to the release of residual stress. Correction sawing should be performed to correct warps, so warps decrease the yield of lumber.

Optimizing radiata pine drying schedules

Wood Material Science & 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 ...

Dry kiln scheduling in furniture production

IIE Transactions, 1999
In this paper, a dry kiln scheduling problem from the furniture manufacturing industry is considered. Factory-specified due dates for orders, kiln availability, kiln capacity, and travel time from the kilns to the factories are all incorporated in a model which is formulated as an integer linear program.

Dry-or-buy decision support for dry kiln scheduling in furniture production

IIE Transactions, 2001
In this paper, a dry-or-buy cost model for a dry kiln scheduling problem in the furniture manufacturing industry is considered. Factory-specified due-dates for jobs, kiln availability, kiln capacity, and drying and buying costs are incorporated into an Integer-Programming (IP) model. As it may be difficult (i.e., because of due-dates, kiln availability,

The dry dock scheduling problem

Transportation Research Part B: Methodological
Dry docks are essential facilities for ship maintenance and thus are critical assets of a shipyard. In this paper, we study a dry dock scheduling problem that arises from shipyard operations and management. The problem involves decisions on assigning ships to a set of dry docks and sequencing the ships in each dry dock, subject to complicated but ...

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

Drying Scheduling—A Procedure for Layer Filling Low-Temperature Corn Drying Systems

Transactions of the ASAE, 1982
ABSTRACT A procedure for predicting maximum safe layer filling rates for natural air and low-temperature corn dry-ing systems is presented. The procedure utilizes a drying simulation model, system setup information, minimum airflow requirements and projected field dry down rates to determine bin filling rates.

Drying schedule structure and subsequent post-drying equalisation effect on hemlock timber quality

International Wood Products Journal, 2013
AbstractWestern hemlock (Tsuga heterophylla), was dried using two different schedules with optional conditioning and seven day post-drying equalisation in a covered and climate controlled space that emulates outdoor conditions in south-central Japan from October to May.

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.

Drying Eucalypts for Quality: Material Characteristics, Pre-drying Treatments, Drying Methods, Schedules and Optimisation of Drying Quality

South African Forestry Journal, 1995
SYNOPSIS Drying today is recognised as a vital element in the value-added processing of solid wood products and there is currently a strong emphasis on improving drying quality and reducing drying costs. Eucalypts with their characteristically high shrinkage and low mass diffusivity values are notoriously difficult to season without degrade, especially
