Over 80% Opening Hole Area Through Air Cylinder For All Kinds Of Coated Paper

Through air drying(TAD) technology has changed the principle of drying, it adopts through air drying instead of traditional contact surface heat transfer. It has improved the drying speed greatly, which make the material drying rapidly. As a result, it has greatly improved the utilization efficiency of fiber and material bulkiness. The finished product has better performance of softness and water absorption.

Material

Carbon steel and stainless steel.

Functions

The paper is not dried by the drying cylinder after the traditional press, but directly dried by the TAD cylinder without contacting the paper surface after dehydration through the web;

The paper is not pressed, and the fiber is distributed in three dimensions, with good expansion and permeability, and the fiber utilization rate is increased by 20%. The paper has better water absorption and dust tolerance.

Advantages

The overall design of 3D software has formed a modular and standardized series of products.

Working principle

The core of the working principle of the through hot air drying technology is the adoption of a penetrating cylinder with penetrating ability. In this drying equipment, the hot air is not drawn from the paper surface, but passes through the paper web, carries the moisture in the paper, and then passes through the cylinder web into the penetrating cylinder. The hot and wet air in the cylinder block is extracted by the fan, then some fresh air is added, and some waste air and moisture are discharged. The remaining air is heated by the combustion furnace and then circulated again to continue drying the paper.
