In a press area, a wet paper is pressed against a heating surface to heat the wet paper with a conveying surface to conveying the wet paper to form a pressure regulating gap between the heating surface and the conveying surface. The pressure regulating gap is provided in a size less than a thickness of the wet paper and more than a thickness of recycled paper to be produced therefrom.

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.

The electrode drying device includes a transfer unit that transfers an electrode sheet having an electrode slurry coated onto the current collector, and a drying chamber including an inflow port where the electrode sheet transferred by the transfer unit enters, wherein an interrupting member for adjusting the flow amount or flow velocity of outside air flowing in a drying chamber is formed at the inflow port, and a height of a central part of the interrupting member is different from a height of a peripheral part of the interrupting member.

Provided are an electrode plate drying device and a coating device, and relates to the technical field of batteries. The electrode plate drying device includes an oven, a first deflector roll, and a second deflector roll. The oven is configured to dry an electrode plate. The first deflector roll and the second deflector roll are disposed in the oven. The electrode plate winds around the first deflector roll and the second deflector roll. Positions of the first deflector roll and/or the second deflector roll in the oven are tunable so as to adjust a movement distance of the electrode plate in the oven.

Provided is an electrode drying apparatus including a moisture supply unit capable of setting the internal temperature of a drying oven to a reference value, which is a level at which the drying of an electrode to be dried is stabilized, before an electrode drying process using hot air is started, thereby preventing the electrode from being fractured by over-drying at the early stage of drying the electrode in the drying oven, and an electrode drying method using the same.
