Definitions
- the glue phase (typically, with a water content in the range 35-60%), a large part of the water is evaporated off, and the properties of the glue matter in the materials (the residual fluid) now dominate the physical properties of the material. This leads to the resistance to rotation is increasing considerably, and this must be compensated for by increased power uptake. Furthermore, the degree of heat transfer is reduced in this phase.
- the content of gluey or sticky materials in the fluid will, within a given range of water content, cause the material to aggregate into large lumps, with large resistance to shear forces. This aggregation also results in the available surface of the material that is to be dried being greatly reduced. As the evaporation process is mainly a surface process, this aggregation will lead to the heat transfer being reduced considerably.
