The present invention relates to a method for drying wood by using microwaves. The method for drying wood by using microwaves, according to an embodiment of the present invention, comprises the steps of: preparing wood; wrapping at least a portion of the wood by using a wrapping member; applying microwaves to the wood wrapped with the wrapping member to raise the temperature inside the wrapping member; removing the wrapping member from the wood wrapped with the wrapping member; and drying moisture of an outer layer of the wood from which the wrapping member has been removed.

Near InfraRed NIR technology, including NIR cameras and detectors, and machine learning methods and systems, including one or more Machine Learning (ML) based surface irregularity prediction models, are used to accurately identify surface irregularities on a surface of a wood product, such as a veneer sheet or ribbon, and provide irregularity prediction data for the wood product. Based on the irregularity prediction data for a given wood product, one or more actions are taken with respect to wood product or the production process to ensure the wood product is put to the most efficient, effective, and valuable use.

Near InfraRed NIR technology, including NIR cameras and detectors, are used to detect irregularity in the surface of a wood product. Based on the detected irregularities at various locations in a given wood product, one or more actions are taken with respect to a production process used to produce the wood product to ensure the wood product is put to the most efficient, effective, and valuable use.

A method for manufacturing a transparent heat-insulation building material from waste wood is provided. The method includes the following steps of: step S1, wood pretreatment, drying immersing, heating, adding a complexing agent solution, stirring, then drying the wood; step S2, wood acetylation treatment, loading the wood into a pressure vessel, adding acetylation fluid, reducing the pressure, and then pressurizing and raising a temperature; step S3, resin impregnating, adding a methyl methacrylate monomer solution and heating it, adding the methyl methacrylate monomer and benzoyl peroxide, bleaching the wood by hydrogen peroxide, and placing them in a vacuum permeator to allow the prepolymer liquid to penetrate into the wood and collecting the prepolymer liquid; and step S4, hot press molding polymerizing the wood in an oven and sleeving it into a heat press molding to obtain a densified wood.

Methods and articles of manufacture relating to engineered hardwood flooring are provided. Engineered hardwood flooring is produced by drying a structural layer comprising a hardwood to a moisture content from about 0.1% to about 3%, whereupon a cell structure of the hardwood collapses. The dried structural layer is humidified to where the hardwood has an increased moisture content greater than about 3%. First and second outer layers are adhered to respective first and second sides of the structural layer to form an engineered product, the structural layer sandwiched by the first outer layer and the second outer layer.

Alcoholic spirits may be artificially aged under highly pressurized carbon dioxide. The carbon dioxide may form carbonic acid, which may cause various esters to form in the presence of wood as well as to mellow the flavor when no wood is present. Wood may be pretreated with ozone, which may extract lignin which may further convert to vanillin during pressurized CO2 treatment, giving a vanilla note. After processing with pressurized CO2, a post-treatment of ozone may be given to the spirit, which may cause a mild oxidation and further mellowing of the spirit.

A method for treating wood packaging materials using Radio Frequency heating includes the steps of heating wood packaging materials using RF heating and applying a pressure before the heating or incrementally applying a pressure during the heating until a temperature of the wood packaging materials reaches at least 60 C. and that temperature is maintained for at least 1 minute.

The present invention relates to a process for preparing a modified wood product wherein the wood is treated with low-molecular weight resin based on lignin degradation products. The present invention also relates to a modified wood product produced using said process.

According to the present invention there is provided a method of treating timber with a creosote-containing preservative formulation adapted for use at substantially ambient temperature. The formulation comprises: creosote; one or more surfactants such that when diluted with a predetermined quantity of water, the creosote is present as an oil-in-water macroemulsion or microemulsion; and optionally, an anti-foaming agent and/or a fire retardant. It is found empirically that the inventive concentrate allows for the use of creosote, a known-effective biocide, without many of the drawbacks inherent in such use.

A system and method for the treatment of invasive pests includes an irradiation device that can generate an electron beam that is applicable to a tree infected by an invasive pest, wherein the electron beam provides an in-situ treatment for the tree infected by the invasive pest by killing the invasive pest via electron beam irradiation. One or more temperature sensors can be used to track the internal temperature of a tree surrogate. A differential temperature difference tracked by temperature sensor can be used to ensure that a reduction in temperature of the tree is attributable to the electron beam rather than increase in heat.
