The invention relates to a device for drying wood, comprising: a container (1) for accommodating the wood (2) and a plate (4, 4′, 4″) forming a wall (3) of the container (1, 1′, 1″, 1″), wherein the plate (4) can be heated and wood (2) at least partially lies against the plate (4).

The present disclosure relates to a facility for forming a wood plastic composite by mixing and extruding wood powder and a polymer resin. According to a facility of the present disclosure, in a process of forming a wood plastic composite, gas and water vapor contained in wood powder and polymer resin are efficiently removed, and thus, a coupling force between wood powder and polymer resin increases, and also, wood powder is uniformly dispersed inside polymer resin, and thus, physical properties of a wood plastic composite to be formed is not degraded, and in addition, since there is no stagnant section while molten liquid of wood powder and polymer resin passes through each apparatus in the facility, wood powder is prevented from carbonizing or polymer resin is prevented from solidifying, and thus, physical properties of the wood plastic composite to be formed are maintained constant.

A device and process for heating wood for the purpose of eradicating burrowed pests such as gypsy moths and emerald ash borer beetles are disclosed. The device is used for treating firewood and pallets made of wood to insure that burrowed pests are killed before transporting the wood across state lines in following of state regulations. The device comprises a conveyor adapted for transporting firewood or pallets an insulated and heated chamber. The wood core temperature of the wood is monitored using wireless temperature sensors. Conveyor speed is adjusted according to temperature readings in order to achieve a threshold wood core temperature and in order to maintain the threshold wood core temperature for the minimum required period of time.

A fluid product dryer and related methods. Implementations of a method for drying particles may include: introducing particles through an inlet into a first fluid bed section; migrating the particles onto a bed deck; injecting a gas towards the particles through openings in the bed deck; migrating some of the particles through a variable-sized gate opening between the bed deck and a riser; migrating a portion of the particles into the riser; propelling the portion of the particles in the riser upwards by an injection of a gas into the riser; directing a first fraction of the portion of the particles out of the first fluid bed section and into a second fluid bed section through an outlet using a deflector feature; and directing a second fraction of the portion of the particles onto a bed deck of the second fluid bed section by interaction with an impingement feature.

A method and device for drying wood chips to be used as raw material for a gas-generating reactor, the device being disposed between the storage for wood chips and the reactor. Product gas of the reactor is at least partially used in a block-type thermal power station (BHKW), and hot air from the housing of the block-type thermal power station is used to heat and dry wood chips in a drying hopper which has at least one outlet for the cooled humidified air. The wood chips enter the drying hopper through a first air-tight lock and exit the drying hopper through a second air-tight lock.

An apparatus for drying bulk goods and a method are provided for continuously drying bulk goods. In particular, an apparatus and a method is provided for drying wood fibers.

In an apparatus (1) for dewatering wood material (2), a first roll (3) and a second roll (4) form a nip (N1) in which water can be pressed out of the wood chips (2). An endless permeable conveyor (5) is arranged to pass through the nip (N1) and carry wood chips (2) through the nip (N1). A method of dewatering wood material uses the inventive apparatus.
