Abstract

Shear rate-shear stress data for Bengal gram (Cicer arietinum) flour suspensions were obtained using a concentric cylinder viscometer. Effect of concn. (30, 33, 36, 39, 42, 45 and 48% flour) and particle size (60-85, 85-100, 100-120, 120-150 and 150-170, British Standard sieves) on flow behaviour index, consistency index and apparent viscosity were investigated. The Bengal gram flour suspension was pseudoplastic and exhibited yield stress. The Herschel-Bulkley model was applicable for fitting the shear rate-shear stress data (r2 <greater than or equal to> 0.95, P <less than or equal to> 0.01). The thixotropic characteristics of the fluid were studied at shear rates of 85.1 and 1337.6 s-1 at 42% flour concn. for coarse (60-85) and fine (150-170) fractions. The equilibrium shear stress and thixotropic coeff. with time and with increasing shear rate were also computed. Particle size and concn. of flour strongly influenced the rheological behaviour of the suspension.
