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.

A model of through-air drying of tufted textile materials

International Journal of Heat and Mass Transfer, 2002
Abstract A transient two-dimensional mathematical model is developed to simulate the through-air drying process for tufted textile materials. The heat and mass transfer in a cylindrical porous medium and the air flowing around it are analyzed separately.

Fundamental characteristics of combined impingement and through air drying of paper

The 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.

The influence of grammage and pulp type on through air drying

Nordic Pulp & Paper Research Journal, 2015
The influence of grammage and pulp type on through air drying was studied. The temperature of a sample was measured during the drying process and the observed temperature changes were used to evalu ...

Quantitative analysis of combined impingement and through air drying of paper

The 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.

Cold dry air-induced rhinitis: effect of inhalation and exhalation through the nose

Journal of Applied Physiology, 1995
Ten subjects with a history of cold air-induced nasal symptoms participated in a randomized two-period crossover study to evaluate the occurrence and magnitude of the reaction induced by inhalation and exhalation of cold dry air through the nose. The protocol involved breathing of either warm moist or cold dry air for 45 min at resting breathing rates.

Estimation of Equilibrium Moisture Content and Drying Time of Potato Through Hot Air Drying

2016
The micro-organisms and bacteria lead the decomposition/decay of moist potato. These failures are almost negligible when the moisture content of potato is reduced below 10 %. Convective drying effectively prevents those defects/failures in the food stuffs. An experimental facility is developed for convective drying of moist object.

PAPER DRYING: A STRATEGY FOR HIGHER MACHINE SPEED. I. THROUGH AIR DRYING FOR HYBRID DRYER SECTIONS

Drying Technology, 2001
For all grades of uncoated paper heavier than tissue, the search for new drying technology has recently become directed towards finding combinations of air drying with cylinder drying which have advantageous techno-economic characteristics. Air drying exists in two forms, through air drying and impingement air drying.

Analyzing Convective Heat and Mass Transfer in Through-Air Drying of Fabrics

Textile Research Journal, 1999
In studying the through-air drying (TAD) of tissues and towels, the drying and heating of TAD fabrics as part of the overall system is considered for the first time. For a simple, single-layer TAD fabric structure, convective drying and heating is modeled using well- known heat and mass transfer models developed in general chemical engineering ...
