Abstract

Experimental data of dependence of density and viscosity of maltodextrin solutions from temperature which is necessary for evaporative apparatus calculation to projection and modernization of industrial arrangement are received. Equilibrium concentration of maltodextrin solutions is determined.

Mathematic model of polysaccharide dissolution in rotary-disk tape evaporative apparatus is calculated and constructed. The scheme that demonstrate gradient of concentration in the near-wall layer of soluble substance is received
