The Infuence of Rheology and Design of Modeling Rolls On the Flow and Specific Gravity During Dough Rolling and Injection

Abstract

The assessment of the viscous medium flow’s transformations under the influence of a component of the technological process and equipment during the redistribution of the formed local injection zones constantly requires the search for areas of improvement in both the process and the machine with rollers. Forecasting of structural and technological parameters, considering possible overloads at the change of rheology and flow of the medium, are based on research, analytical models, and computer simulations. The analysis of the action of working bodies at various loadings on the environment is carried out and the possible flow between rotating rolls with changes of structural and mechanical properties in processes of formation of a product is considered. The interaction of constructive factors with technological ones under the conditions of observance of all operating modes of the machine during its operation is established. The optimization of the parameters of this class of machines with the choice of analytical methods under the conditions of the necessary models and their development, taking into account a number of factors influencing the processes of unloading, injection, transportation of viscous media, is discussed. This is based on the result of the processes of transfer of a large enough volume with a directed flow and the pulsating motions of different scales of variables applied to it, both in time and space mathematical modeling of the influence of rheology and design parameters of forming rolls on the flow in the gap between rotating rolls and determination of useful specific power when rolling and forcing the dough. The

proposed techniques allow establishing the quality of rolling the mass of the medium to the appropriate thickness when injecting roller working bodies and determining the speed and pressure formed, which depends on its physicochemical properties, the shape and location of the rolls.
