The Chemical Nature of Kiln Brown Stain in Radiata Pine

Holzforschung, 2000
Summary This paper presents results of a study on the chemical nature of kiln brown stain (KBS) that develops in kiln dried radiata pine (Pinus radiata D. Don) sapwood. KBS is a chocolate brown discolouration which develops approximately 0.5 mm under the timber surface.

Effects of two fumigants and a fungicide formulation on the development of kiln brown stain in radiata pine lumber

European Journal of Wood and Wood Products, 1998
Two fumigants (methyl bromide and sulphuryl fluoride) were used to treat freshly sawn radiata pine (Pinus radiata D. Don) lumber and log sections to evaluate their influence on development of kiln brown stain. Both treatments reduced severity of stain when compared with controls.

Application of a novel de-watering process to control kiln brown stain in radiata pine

European Journal of Wood and Wood Products, 2001
mehreren Trocknungszyklen mit Pressluft zwischen 10 und 100 bar unterworfen. Danach wurde die Abnahme der Feuchte, der Feuchtegradient entlang der Proben und das Ausmas der Verfarbung durch Braunverfarbung bestimmt. Die Ergebnisse zeigen, das die Anwendung der Druckzyklen bis 100 bar zu einer gleichformigen Feuchteverteilung fuhrt mit Mittelwerten um ...

Mitigation of Brown Stain in Ponderosa Pine Shop-Grade Lumber Using High Temperatures Early in Kiln Schedules

Forest Products Journal, 2013
ABSTRACT Brown stain makes the appearance of ponderosa pine shop lumber look dark, streaky, and splotchy, which often results in lumber downgrading. When brown stain occurs in a piece of shop lumber, it is often sorted separately and ultimately sold for a discount.

Influence of Kiln Venting on Brown Stain inPinus RadiataSapwood

Drying Technology, 2007
This study assesses the influence of a closed drying environment on kiln brown stain in Pinus radiata sapwood. Three sets of matched timber samples (N = 50) were dried at low temperature (50°C), one without and two with kiln venting. Statistical analysis showed that the closed drying environment produced no significant change in the lightness (L∗) of ...

Solutes in sap obtained from supercritical CO₂ dewatering of radiata pine sapwood, and a new role of sap cyclitols in brown stain formation during kiln drying of green wood

Holzforschung, 2019
Abstract Xylem sap obtained from radiata pine sapwood using a supercritical CO2 (scCO2) dewatering process contained a complex mixture of solutes comprising carbohydrates, amino acids, alkanoic and diterpene acids, neutral diterpenoids, β-sitosterol and cyclitols.
