Drying of Seeds and Gels

ABSTRACT

In an attempt to contribute to the integration of research that deals with the drying of seeds and gels, the aim of the present study is to analyze the drying of porous particles covered with a gel layer, whether natural or artificial. Two case studies are presented. In the first case, the emphasis is to study the combined effect of heat and mass transfer and the shrinkage in the drying of mucilaginous seeds. The focus of the second case study is the development of an experimental methodology for coating seeds with a gel-based polymer.

Keywords:

• Heat and mass transfer
• Shrinkage
• Coating
• Porous particle
• Physiological regeneration
