Modelling and simulation of dryer system

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.

A mathematical modelling and simulation framework is 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 machine has been developed by modifying the rotary dryer model.
