Determination of drying behaviour in industrial type convectional dryer and mathematical modelling

Abstract

In this study, the performance of a stenter (ram machine) that enables the drying of textile products with hot air is theoretically modelled with a diffusion model derived from Fick's second law. The experimental study was conducted in a 10 chamber stenter with three different drying temperatures (110-130-150 °C) and three different fabric speeds (10-20-30 m per minute.) by using a fabric consisting of 95% cotton + 5% lycra. The drying behaviour of the dryer was determined by utilizing the data obtained from the studies. With the help of the utilized model, the values of diffusion coefficients and activation energies were obtained, the conformity of data between the model and the experimental studies were compared by using regression analysis, it was observed that the R 2 value varied between 0.9812 and 0.9961.

Computational Fluid Dynamic Simulation of Fabric Cooling in a Stenter Machine

“…The energy consumption of the stenter machine was predicted with a 14% error of absolute errors in their study. Akan and Özkan [10,11] carried out an experimental study using fabric with 95% cotton + 5% Lycra content at three different air-drying temperatures (110-130-150 • C) and 10 m/min fabric velocity by operating a stenter machine with 10 cabins under real production conditions. They showed how different air-drying temperatures affected the heat-transfer coefficients and energy efficiency.…”
