“…It commonly relates the energy required for moisture evaporation at the solids feed temperature to the total energy supplied to the dryer. The instantaneous energy efficiency quantifies a fraction of available energy that was used for evaporation (Menshutina, Gordienko, Voynovskiv, & Kudra, 2004):…”

“…Published data revealed that the amount of energy consumed is a very alarming concern in some industries, such as the manufacturing of wood products (70%), textile fabrics (50%), and pulp and paper (30%). [2] Overall, energy consumption due to drying is around 15-20%, which is substantially high. At the industrial scale, the colossal dimensions of a dryer may be impressive.…”

The article surveys the drying of solids materials and polymer solutions when infrared radiation (IR) is employed as the main heating source. The study reviews the current research trends of IR drying of specific applications. A case study similar to an industrial setting is presented to illustrate a model development and control scheme of an IR drying unit. The design and online implementation of an internal model controller (IMC) is discussed. The study demonstrates the controller capabilities to suppress random variations of the moisture content in the material entering the dryer. Simulation results also showed the success of model predictive control (MPC) multivariable controller ability, while handling process interactions and process constraints, to track setpoint changes in the humidity and temperature of the material exiting the dryer and to reject unmeasured stochastic disturbances in the inlet humidity stream. INTRODUCTIONEven though drying is an old and well-established process, the transport phenomena characterized by a simultaneous transfer of mass and energy is an interesting and fascinating area to study. In a recent survey, Mujumdar [1] reviewed the most important aspects of drying technology. He highlighted the R&D research trends in this area from conventional to new technologies. Energy saving and product quality are among the main concerns in industry today. Thermal drying, being defined as the removal of moisture from a solid, is one of the most ubiquitous and energy-intensive processes. Firstly, the energy required for a drying process can be supplied by different means to adapt the drying requirement of a variety of products and also to satisfy the industrial and market demand. Thus, efficient use and management of energy are very desirable in the design and operation of a drying unit. In fact, energy

SUMMARYThis paper reveals a new method for drying of textiles with the combination of vacuum-extraction and convective drying methods. The new method provides an inconceivable fast drying due to the synergistic effect of heat energy and mechanical forces. During vacuum extraction, hot air or superheated steam was applied as suction in place of air at room temperature and named as shock pre-drying. Vacuum extraction and shock pre-drying of cotton woven fabrics were performed at several working speeds between 1 and 30 m min À1 and the drying effects were compared. It was observed that it was possible to obtain effective pre-drying in 1 3 s or less time with shock pre-drying method. The method's water removal efficiency mainly depends on working speed and hot air or superheated steam temperature.
