A drying apparatus for drying a material belt includes at least one material-belt turning mechanism, used for changing a travel direction of the material belt, and including a first passing roller, a turning roller, and a second passing roller sequentially arranged in the travel direction of the material belt. The turning roller is configured to move in a first direction relative to the first passing roller and the second passing roller to adjust a wrap angle of the material belt on the turning roller, the first direction perpendicular to an axial direction of the turning roller.

Methods and devices for agitating material. In some embodiments, an agitator is positioned in a receptacle to agitate material therein. The agitator may include a shaft, an arm extending from the shaft, and at least one knife extending from the arm. In some embodiments, the agitator may further include one or more agitator elements operably connected to at least one knife.

A drying device having a travel path along which a web (W) of paper travels, a plurality of drying ovens arranged side by side along the travel path, a plurality of conveyor rolls provided in each of the drying ovens to convey the web (W) along the travel path, a plurality of roll units each constituted by one or more of the conveyor rolls and separated from each other along the travel path, and a plurality of conveyor motors connected to the respective roll units to rotate the conveyor rolls, wherein a downstream one of the roll units with respect to the travel path is rotated at a lower rotating speed than an upstream one of the roll units.

A heating apparatus includes a plurality of heaters to heat a heating object, a plurality of air nozzles to blow air onto the heating object, and a blower to supply air to the plurality of air nozzles. The plurality of heaters is disposed along a conveyance direction of the heating object, at least one of the plurality of air nozzles is disposed between adjacent two of the plurality of heaters, and the plurality of air nozzles blows air onto the heating object while the plurality of heaters heats the heating object in both cases of when the heater performs a heating operation and when the heater does not perform the heating operation.

A conveyor for printer includes, a first guide, a second guide disposed separately from the first guide, a third guide disposed between the first guide and the second guide, the first guide, the second guide, and the third guide defining a conveyance path along which a medium is conveyed, and a loading guide movable to guide the medium between the first guide and the second guide. The third guide is movable between a first position and a second position. The third guide presses the medium to the first guide and the second guide at the first position and is separated from the medium at the second position. The loading guide is disposed at a guiding position to guide the medium and is disposed at a retracted position retracted from the guiding position in response to the third guide disposed at the first position.

A feeding device is provided for a belt drying installation for dump or sewage sludge material dewatered down to a pasty consistency. In the conveying path of the sludge material, a first roller having transverse grooves that are set back relative to the outer diameter of the roller and a guide device are arranged relative to the outer diameter of the first roller such that when the roller is rotated the sludge material is drawn into the transverse grooves and is shaped to elongated extrudates. The first roller is associated with a comb which has teeth that rigidly engage the transverse grooves and which sweeps the extrudates from the transverse grooves, wherein the tips of the teeth which rigidly engage the transverse grooves define a line of engagement. The tooth tips which rigidly engage the transverse grooves are beveled towards the tooth neck.
