Abstract: 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.

Abstract: It is provided in a liquid application system for applying liquid to a material cake transported on a conveyor device having a liquid application device, that the conveyor device comprises a porous section on which the material cake lies or which the material cake contacts and which is permeable for a liquid to be applied, that the liquid application device comprises an application device via which the liquid to be applied can be applied to the side of the porous section of the conveyor device facing away from the material cake, and that the liquid application device comprises an overpressure chamber having a first overpressure relative to the environment by which the porous section of the conveyor device passes, wherein the applied liquid can be transported via the first overpressure through the porous section of the conveyor device or held via the first overpressure to the porous section.

Abstract: A device for wetting particles, in particular wood particles, with an application agent, at least one conduit transporting a fluid as a fluid stream and an end section which forms an outlet. The fluid can be introduced in the direction of the main flow into a container containing the particles, via the outlet. The particles are in the container in a loosened state and/or can be loosened. The application agent, for spraying by a nozzle device with a speed component directed against the main flow direction, can be introduced into the fluid stream and can be guided to the particles by the fluid stream.

Abstract: The invention relates to wetting agents for wetting working material for producing pressed material boards, comprising polyols, acylglycerides or acylglyceride derivatives, surfactants, and water.

Abstract: The invention relates to a moistening system (1) for presses (100) for compressing material cakes (200) mixed with binding agents, preferably continuously operating presses (100), in particular for producing composite panels, preferably engineered wood boards, comprising a first moistening agent application device. The first moistening agent application device (3) comprises a first application roll (7), which can be set from above against the material cake (200) conveyed by a conveyor unit (300) of the press, at least one first dosing roll (9), which can be set against the first application roll (7), and a first moistening agent bath (11). The at least one first dosing roll (9) is immersed in the first moistening agent bath (11) for taking up moistening agent and comprises at least one wiper roll (13), which can be set against each first dosing roll (9) and by means of which the amount of moistening agent taken up by each first dosing roll (9) can be adjusted.
