It is not possible here to discuss all forms of dryers or their applications, and further research is needed due to the development of new products and processes. In recent years, new drying processes, although rare, have made breakthroughs, such as pulse combustion drying in industries where food, agriculture, waste treatment, forest products, minerals, and chemical products are operated on a large scale. The device replaces the traditional method, the sudden-type spray fluidized bed and the vibrating bed dryer, and its practicality will gradually increase with the accumulation of practical experience. Therefore, it is crucial and urgent for the technicians who choose the drying equipment to be familiar with the development level of modern drying technology. Only then can he make reasonable demands on the dryer designers and providers.
