An apparatus (1) and a method for dewatering wood material (2). The apparatus (1) includes a first roll (3) and a second roll (4) that form a nip (N i) in which water can be pressed out of the wood chips (2). An endless permeable conveyor (5) is arranged to pass through the nip (Ni) and carry wood chips (2) through the (Ni).

The technology disclosed relates to moisture removal from wood materials. In particular, it relates to a press that includes a continuous and liquid permeable sheet metal band that makes use of viaways, grooves, perforations, or combinations thereof allowing liquid to permeate therethrough. The press can also include a first pressing roller located above the sheet metal band and a first anvil roller located below the sheet metal band and forming a first nip with the first pressing roller and the sheet metal band, such that the sheet metal band being located between the first pressing roller and the first anvil roller.

The invention relates to a chain link for a support chain for supporting a compression belt in a separating device for separating materials of different flowability, the chain link having a support surface and an inner surface opposite said support surface and is characterized in that a protruding support element is arranged on at least one end face of the chain link so as to form an undercut. The invention further relates to a support chain for a support apparatus for supporting a compression belt in a separating device for separating materials of different flowability, the support chain being an articulated chain which has individual chain links connected to each other in an articulated manner, the chain links being threaded onto chain pins extending transverse to the conveying direction F with the chain links according to the invention. The invention also relates to a support apparatus having the support chain according to the invention.

A soft material separator (1) has a perforated drum (2) A pressing band (3) is guided along a circumferential section (19) of the perforated drum (2) and can be operated together with the perforated drum (2). A feed zone (7), from which a substance mixture (14) consisting of substance components (12, 13) of different consistencies is drawn in between the perforated drum (2) and the pressing band (3) to separate the substance components (12, 13). For optimization in terms of wear and energy consumption without any or without significant losses in effectiveness of the device, a detection system (9) is provided to quantitatively determine the fill level of the feed zone (7), and a control apparatus (10) which is connected to the detection system (9) is provided to adjust the speed of the perforated drum (2) and of the pressing band (3) depending on the fill level.

An apparatus for separating mixed materials of different flowability includes a frame structure, a hollow drum with a perforated peripheral surface driven in rotation and mounted on the structure, a continuous compression belt pressed against the peripheral surface from outside when wrapped around part of the drum circumference and driven in circulation, a product intake wedge formed by the belt and drum for conducting a product stream, into the apparatus between the drum and the belt in an inlet area of the product stream, and a support apparatus for the belt, with at least one support element which is arranged on the side of the belt opposite the drum, wherein the support element is configured as a roller track with at least partially spring-mounted rollers arranged successively in the conveying direction. The spring force of at least individual rollers is controllable. A corresponding method is also provided.

An apparatus for separating substances of different flowability includes a housing base, a hollow drum having a perforated peripheral surface which is arranged on the housing base and is driven in a revolving manner, a continuous press belt pressed from outside against the hollow drum, while wrapping around a portion of the circumference of the hollow drum, and which, together with the hollow drum, forms an intake wedge for the material to be pressed. The press belt is mounted by at least one drive roller and at least one bearing roller, and is distinguished by the fact that the drive roller is mounted on a bearing support. The bearing support is arranged on the housing base so as to be adjustable in terms of position. A corresponding method is also provided for adapting the apparatus.

An apparatus configured to separate substances comprising: a frame structure; a hollow drum, wherein the hollow drum is driven in rotation and comprises a perforated circumferential surface and an at least partially open end side; a press belt wrapped around the perforated circumferential surface; a product intake wedge, wherein the product intake wedge guides a product flow into the apparatus; a support apparatus comprising a support element, wherein the support element is located on a side of the press belt opposite the hollow drum; and a device configured to discharge separation material pressed through the perforated circumferential surface, wherein: the separation material is pressed into a hollow space of the hollow drum, the separation material is pressed from the end side of the hollow drum, and a cooling device cools the separation material with a cryogenic cooling medium.

An apparatus for separating mixed together substances of different flowability has a frame structure and a hollow drum with a perforated circumferential surface driven in a revolving manner and mounted on the frame structure. A pressing element lies externally in the region of the circumferential surface of the drum and is driven in a revolving manner, such that the drum and the pressing element form a product intake wedge for the feeding in a product stream, of material to be pressed. The drum and pressing element also form a pressing region. A discharge element is associated with the pressing element downstream of the pressing region in the product stream conveying direction, for discharging residues that remain on the pressing element after pressing. The discharge element is an actively drivable, endless discharge belt for discharging the residues in a discharge direction. A corresponding method is also provided.
