Section 4 Chapter 1 Fundamentals - Sahand University of ...

2003-9-21  Drying is a complex operation involving transient transfer of heat and mass along with several rate processes, such as physical or chemical transformations, which, in turn, may cause changes in product quality as well as the mechanisms of heat and mass transfer. Physical changes that may occur include: shrinkage, puffing, crystallization, Limestone transitions. In some cases, desirable or undesirable chemical or biochemical reactions may occur leading to changes in color, texture, odor or other properties of the solid product. In the manufacture of catalysts, for example, drying conditions can yield significant differences in the activity of the catalyst by changing the internal surface area. Drying

Drying Method - an overview ScienceDirect Topics

Spin-drying in an environment purged by dry hot N 2 can mitigate other dryer-generated defects, such as watermarks after HF processing. For batch spin–spray processors or single-wafer spin tools, the drying is done in situ after the chemical processing step and rinsing. For wet benches, a separate module is used.
