Through Air Drying

Drying Technology, 2003
Process of through-air-drying is becoming increasingly popular in the manufacture of textiles, non-wovens, tissue, and towel. Very high drying rates, enhanced product properties, i.e., softness, bulk, absorbency, unique 3D structure are the driving forces behind its increasing popularity.

Combined Impingement and Through Air Drying of Paper

Drying Technology, 1997
ABSTRACT For this combined drying process the fundamental characteristics were determined using a unique facility in which air convection drying of paper could be investigated over the full range from pure impingement to pure through drying. As well as light weight paper the program tested heavier sheets, of printing paper grammage, which are not ...

Mass Transfer Coefficients and Drying Rates in Through Air Drying: Part II

Drying Technology, 2009
In this study experimental results and analysis are given of convective heat and mass transfer in the drying of tissue and towel products (25 and 50 g/m2 basis weight) under commercially realistic conditions under through flow. Parameter effects on drying rate include process variables such as refining, shaping, commercial forming, initial moisture ...

Fundamental characteristics of combined impingement and through air drying of paper

Canadian Journal of Chemical Engineering, 1997
AbstractAn experimental facility was developed to determine fundamental characteristics of combined impingement and through air drying of paper. Removal of impingement boundary layer humidity by through flow makes both components of the combined process nonadiabatic, complicating the analysis.

Quantitative analysis of combined impingement and through air drying of paper

Canadian Journal of Chemical Engineering, 1997
AbstractModels were developed and verified to represent the water removal rate data of the two components of combined impingement and through air drying process. Eight physically meaningful parameters were identified, determined, correlated and analyzed. The increasing rate period is extended by impingement water removal.

Through Air Drying Characteristics of Machine-Formed Semi-Permeable Paper

Drying Technology, 1997
ABSTRACT Printing and heavier grades paper are dried over steam heated cylinder dryers, a mature process which is characterized by low drying rates and lack of ability for control of moisture uniformity across the sheet. The present study examines factors relating to the applicability of through air drying for such grades of paper.

Experimental Investigation of Through Air Drying of Tissue and Towel under Commercial Conditions

Drying Technology, 2007
An experimental setup was developed to study the through air–drying characteristics of permeable grades such as tissue and towel under commercially relevant conditions of basis weight, airflow rate, temperature, and humidity conditions. The experimental setup is capable of evaluating the transient fluid flow, heat, and mass transfer characteristics of ...

Mechanism of Through Air Drying of Paper: Application in Hybrid Drying

Drying Technology, 2003
Abstract During through air drying the internal sheet drying history develops as a succession of local moisture content profiles in the sheet thickness dimension. These profiles were determined by interrupting the through drying of 180 g/m2 6-ply sheets, then quickly delaminating and determining the moisture content of each 30 g/m2 ply.
