    Abstract: A process and apparatus for the preparation of a modified lignocellulosic material by treating the lignocellulosic material in a first activator zone having an atmosphere of one or more acid anhydrides in vapour form in a gas at a gauge pressure of 0-50 kPag and a temperature of 100-160° C., and then treating the lignocellulosic material in a second reactor zone having an atmosphere of a gas at a gauge pressure of 0-50 kPag and a temperature of 120-190° C., thereafter stripping the lignocellulosic material with steam or water in a stripper zone, and optionally further processing. The process is more efficient as compared with the prior art processes by providing a better access of the acid anhydrides to the sites of the reactive lignocellulosic hydroxyl groups (—OH), which are located on the internal surfaces of pores and capillary channels in the lignocellulose. Furthermore, the apparatus is relatively simple. This makes the inventive process and apparatus suitable for a cost-efficient preparation of modified lignocellulosic fibre in industrial scale.

    Abstract: In manufacturing pressed boards, a flowable mixture of thermosetting resinous material and filler is blown through one or more nozzles into a converging throat formed by a pair of relatively inclined perforated conveyor bands in which the mixture is compacted into a continuous, coherent but preferably still pliable web by the application of heat to preset the resinous material thereof. The web may be immediately converted into a rigid board by being led, without intermediate cooling, into a continuously working press for final condensation of the resin; on the way to that press it may be subjected to a finishing operation, as by adhesion of preheated strips of paper or other coverings to its still tacky surfaces.

    Abstract: A device and method for elutriating and gluing wood chips. At least one elutriating apparatus is used to fractionate the wood chips into at least one coarse chip fraction and one fine chip fraction. The elutriating apparatus has a fall duct and is designed so that the chip fractions pass through different gluing regions in the fall duct. At least one gluing apparatus is provided in order to glue the chip fractions in the gluing regions. Thus, the chip fractions can be glued in a common apparatus specifically with a glue amount adapted to a particular average chip size.

    Abstract: An improved method for making compressed structural fiberboard by extruding agricultural fibrous matter into said compressed structural fiberboard. The improved method of the present invention includes providing a preselected volume of agricultural fibrous matter and preconditioning the agricultural fibrous matter to have a predetermined moisture level therein. The agricultural fibrous matter is separated and cleaned, and steam is added to the agricultural fibrous matter until a predetermined level of moisture is reached within the agricultural fibrous matter. A predetermined level of borax is also added to the agricultural fibrous matter to prevent the formation of bacteria within the agricultural fibrous matter. The agricultural fibrous matter is conveyed throughout the process on conveyors having variable drives, wherein the level of the agricultural fibrous matter on the conveyors is sensed such that a signal is provided to the variable drives to adjust the speed of the conveyors in order to provide a predetermined level of agricultural fibrous matter. The agricultural fibrous matter is then extruded to form a compressed structural fiberboard.

    Abstract: The present invention provides a system and method for determining adhesive resin distribution on wood flakes to be formed into a wood-based composite. Where a predetermined amount of adhesive resin has been sprayed onto a selected amount of wood flakes being tumbled in a blender, the method includes the steps of: removing a sample of sprayed wood flakes at the output of the blender and placing the sprayed wood flakes on a scanning bed; scanning the sprayed wood flakes with a scanner having at least 1200 dpi resolution with 1800 dpi interpolation to provide image data; using image analysis software with resin analysis macros to filter the image data to provide a high contrast image that shows each adhesive resin spot differentiated from the wood flake on which the adhesive resin spot is situated; and measuring and analyzing the high contrast image to provide an output showing at least a percent coverage of the wood flake by the adhesive resin.
