The invention relates to a device for the gluing of particles, in particular wood particles, including a dryer and a line transporting the stream of particles, wherein the stream of particles is being introduced in a main flow direction into the dryer via the outlet. A binder is supplied to the stream of particles, said binder being introduced via a nozzle device with a speed component directed against the main flow direction.

An improved blending apparatus for manufactured wood products with a rotating blending drum or cylinder with a pattern of alternating flights of different configurations extending from the interior of the drum. The flights lift the strands as the drum rotates to different heights before the strands free-fall back to the bottom of the drum. One flight is shorter, and may be trapezoidal in cross-section. The second flight is taller, and may have a “bull-nose” configuration with substantially vertical sides. During operation, the design of the bull-nose flight tends to hold more strands and to carry them closer to the top of the drum before the strands drop and fall. In contrast, the shorter height and angled sides of the trapezoidal flight tends to hold fewer strands and to not carry them as high along the side before strands drop and fall. The alternating pattern causes a more consistent and dispersed fall of strands as the drum rotates, resulting in a significantly larger and more consistent amount of the sprayed adhesives and waxes being applied to the strands, and not passing through gaps to build up on the drum wall.

A method for applying an adhesive resin in manufacturing an engineered wood product includes pre-heating an adhesive resin to a pre-application temperature before entry into an adhesive applier, maintaining the adhesive resin at the pre-application temperature for a controlled period of time to achieve improved pre-application chemical properties, and applying the adhesive resin on wood particles to form an engineered wood product.

A device for injecting a fluid internally of a flow of loose material, comprising: a feeder (2) of loose material (100), provided with a lower discharge mouth (24) through which the loose material (100) flows along a descending direction (Y); an injector (3), predisposed to inject a fluid onto the loose material (100), which injector (3) is located below the discharge mouth (24) such as to be positioned internally of the flow of loose material (100).
