Drying technology has a wide range of applications, in the face of a large number of industries, physical and chemical properties of different materials, product quality and other aspects of different requirements, drying technology is a cross-industry, interdisciplinary, with experimental scientific nature of the technology. In general, three aspects of knowledge and technology are required in the development and application of drying technology. The first is the need to understand the physical and chemical properties of the dried materials and the characteristics of the use of the products; the second is to be familiar with the principle of transfer engineering, that is, the principle of mass transfer, heat transfer, fluid mechanics and aerodynamics and other energy transmission principles; It is clear that these three aspects of knowledge and technology do not belong to a subject area. In practice, these three aspects of knowledge and technology are indispensable.
So drying technology is a cross-industry, interdisciplinary technology.
