Basic classification of substances according to rheological behavior (viscous, elastic, plastic, viscoelastic), rheological models. Viscosity anomalies, Newtonian, non-Newtonian, combined plasticity types, flow curves and deformation curves. Characteristics of viscoelastic behavior, graphical and mathematical description, model of ideal rheological behavior. Linear and nonlinear viscoelastic behavior, real viscoelastic substances, modules characterizing types of viscoelastic behavior. Rheometry, main types of viscometers (capillary, body, rotary, oscillatory), universal instruments and methods for measuring viscosity, elasticity, viscoelasticity (Instron, texturometers,T-analyzer), devices for empirical measurement of rheological properties in the food industry (Brookfield, Mc Michel, etc.). Classification of cereal laboratory instruments to measuring on an empirical basis (dynamic, static conditions). Devices of cereal labs for measuring of steady deformations (so called static, extenzograph, alveograph, etc.). Devices of cereal labs for measuring of continuous deformations (so called dynamic, farinograph, mixograph, etc.) Devices of cereal labs for measuring of viscometer principle. Measurement of rheological characteristics of semi-solids and solids (bread crumb, biscuits, pasta etc.). Interpretation of results from cereal lab devices in technology and evaluation of cereal product quality |
