A method for producing material boards in a production plant in which apparatuses form a material into a mat that is pressed to obtain the material board which has specific quality parameters. The production plant and/or the apparatuses are controlled in an open- or closed-loop manner by a controller, which preferably includes a programmable logic controller, and input parameters are received, processed and/or output by the controller. The input parameters are formed at least from settable product parameters for the material board to be produced, from settable and/or recorded plant parameters of the production plant and/or the apparatuses and/or from recorded material parameters. A quality value of at least one quality parameter of the material board to be produced is determined based on the input parameters by an algorithm based on artificial intelligence. The algorithm is trained or formed by a database which has at least one quality parameter and input parameters correlating with the quality parameter.

A method for producing a board according to the present invention includes the steps of: (A) dispersing a polycarboxylic acid, a saccharide, and ammonium sulfate in a collection of small wood pieces; and (B) subjecting the collection of small wood pieces containing the dispersed polycarboxylic acid, saccharide, and ammonium sulfate to hot press molding to form a board comprising the small wood pieces bonded together.

A raw-material feeding device includes: a storage section that includes a bottom section and a side wall standing from the bottom section and that stores, in a storage space surrounded by the bottom section and the side wall, small pieces of raw material constituted by a material containing fibers; a stirring section that is provided in the bottom section at a position facing the storage space, that includes a blade which rotates about a rotational axis extending in a direction in which the side wall stands, and that stirs the raw material in the storage space by rotating the blade; a first discharging section that is provided in the side wall so as to communicate with the storage space, that includes a first tubular body rotating about a first axis intersecting the rotational axis, and that discharges, upon rotation of the first tubular body, the raw material in the storage space to a processing section; and a second discharging section that is provided in the side wall at a position different from a position at which the first tubular body is provided so as to communicate with the storage space, that includes a second tubular body rotating about a second axis intersecting the rotational axis, and that discharges, upon rotation the second tubular body, the raw material in the storage space to the processing section.

A novel green manufacturing process for medium and high-density fiberboard (MDF and HDF) production is disclosed, where the green manufacturing process refers to a novel low-emitting manufacture of MDF and HDF in terms of HAP emission. The novel manufacturing process comprises a preconditioning unit operation for raw wood furnish material, where blends comprising two or more woody materials having disparate moisture contents are held in a preconditioning vessel for up to 48 hours under controlled temperature conditions, where the moisture content is homogenized to produce a blend having substantially uniform moisture content. The blend is preconditioned in the novel manufacturing process to facilitate moisture homogenization kinetics, and to uniformly increase the material temperature above the lignin glass transition temperature. Subsequent process steps, such as defibration and fiber drying, require lower temperatures to produce and dry wood fiber, thus lowering HAPs emission.
