Peculiarities of heat exchange in dough under the rotating rollers action https://doi.org/10.33108/visnyk_tntu2019.03.075

Abstract

The analytical analysis of roller impact on the medium and its behavior at deformation
influences are carried out, ways of choosing the optimal method of the process for providing the maximum or
minimum value of parameters (criterion) are proposed. The physical essence of the equation of energy flows of
the medium mass deformation intensity, which depends on the method of applying mechanical forces, the degree
of its previous dispersion (recipe) and its physical and mechanical properties, is considered. For more visual view
and understanding of the overall research performance, the scheme of causal relationships between the medium
and the roller, determining the temperature change of the dough injection process, is proposed. It is noted that the
determination of the influence of deformation processes temperature during the process of medium injection by
roller operating bodies plays an important role for calculations and designing of molding, sheeting equipment.
The influence of thermal circulatory chaotic streamsthe character resulting in general heat circulation disfunction
in the medium during the injection is considered. At the same time, the level of such disfunctions can be deep
enough with changes in the contours directions influencing the process, according to each particular period of the
deformation stage in the injection unit of the molding machine.
