Modelling and Simulation of a Dryer System

Abstract

Drying is one of the complex and highly energy-consuming process unit operation used in many industry such as textile, paper, chemical, pharmaceuticals, agro and food-processing, sugar, etc. Significant R&D efforts are underway in last more than a decade to enhance dryer technology and operations to enhance its energy efficiency. In textile, drying of garments is one of the important unit operations to help the quality of the final product to meet commercial standards. In this work, a mathematical modelling and simulation framework has been developed on the MATLAB-SIMULINK® platform for rotary dryer. The model is semi-empirical based on the first principles using mass balance and moisture balance equations amongst the vegetables and hot air. Later, a mathematical model for textile dryer has been developed by modifying the rotary dryer model. The modification is done as the physical mechanism of both the dryers is different. The model simulator is also validated with the available experimental data.
