Abstract
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.
Claims11
A method of drying a wet paper, comprising:
- moving a heating surface to heat the wet paper with a drying setting temperature for the wet paper in a conveying direction of the wet paper,
- pressing the wet paper against the heating surface in a press area by a conveying surface to convey the wet paper;
- and
- drying the wet paper on the heating surface to make recycled paper, wherein
- a pressure regulating gap, formed in the press area, between the heating surface and the conveying surface is provided in a size less than a thickness of the wet paper and more than a thickness of the recycled paper, thereby regulating a pressure applied in the press area to a target pressure to obtain dry paper without burning on the heating surface.

A waste paper recycling apparatus, comprising:
- a conveyor to convey a wet paper, the conveyor having a conveying surface to convey the wet paper,
- a drier to dry the wet paper on a heating surface with a drying setting temperature for the wet paper, the heating surface moving in a conveying direction of the wet paper,
- a press area to press the wet paper against the heating surface by the conveying surface;
- and
- a pressure regulator to regulate a pressure applied in the press area, wherein
- the press area has a pressure regulating gap between the heating surface and the conveying surface, and
- the pressure regulator regulates the pressure applied in the press area to a target pressure by providing the pressure regulating gap in a size less than a thickness of the wet paper and more than a thickness of recycled paper.
