Název v původním jazyce

Expansion of Starch During Thermal Pressure Forming

Popis výsledku v původním jazyce

The contribution is aimed to the processes of thermal treatment of starch-based materials for biologically degradable packaging products. The combined heating of starch-based suspension (direct ohmic heating and thermal processing of starch based suspensions) was performed in a closed mould. The sample expands significantly during heating and this expansion is accompanied by gradual formation of crust and a porous layer in the core. The mathematical model of the combined ohmic heating of starch suspension was formulated. The FEM model is based upon the concept of two overlapping 2D meshes. The foam behavior is modeled according to the idea of expanding spherical bubble, filled by a saturated steam and with viscoelastic walls. A simplified model of a homogeneous sample will be presented. Parameters of models are identified by comparing the theoretical predictions with the experimental data.
