A drier apparatus includes a cylindrical chamber in which a pair of screw conveyers each including a tubular shaft in which heat medium is able to flow, and carrier blades arranged on an outer surface of the tubular shaft is housed, a motor for rotating the screw conveyers, an input path connected to the cylindrical chamber at a proximal end of each of the screw conveyers, and an output path connected to the cylindrical chamber at a distal end of each of the screw conveyers. The input path and the output path include a device for opening and closing a path. Each of the screw conveyers includes a pair of tubular shafts arranged substantially in parallel with each other, and a plurality of semicircular carrier blades such that the carrier blades form a part of an imaginary spiral plane about the tubular shaft on an outer surface of the tubular shaft, the carrier blade being partially made of a material having a resistance to abrasion.

A dryer (1) for drying particles is provided that includes an enclosure, a circular tray mounted in the enclosure, the surface of which is perforated and permeable to gases, a distribution system and a recovery system for particles. The dryer also includes a hot-gas blowing system with N fans designed to generate a flow of hot gas along N gas columns, each gas column i passing through a different angular section (1.i) of the tray. Having passed through the (N1) first angular sections of the tray, the (N1) first gas columns are extracted from the enclosure or recirculated after drying and heating. Having passed through the Nth angular section (1.N) of the tray, the hot gas of the Nth gas column is recirculated by the Nth fan (5N) to form the first gas column (1.1) passing through the first angular sector (1.1) of the tray.

The disclosure relates to a method for drying wood products with reduced discharge of VOC.

A plant for wood machining, comprises: a plurality of user points with a respective exhaust duct of the fumes to be filtered; at least one piece of equipment comprising at least one hollow filtering chamber defining at least one internal volume and comprising a filter or a filtering device/apparatus/unit/component/equipment/structure or the like of the fumes to be filtered to obtain filtered fumes housed at least partly in the internal volume, the filtering chamber being provided with: one inlet port and one outlet port of woody material; at least one introduction opening of the fumes to be filtered communicating with the exhaust ducts; and at least one evacuation opening of the filtered fumes towards the outside; wherein the fumes drying the woody material in its passage the inlet port towards the outlet port.
