Dynamics of interaction of components during mixing

Abstract

The effect of mechanical action on the mixing and whipping of the mixture of components contributes to the formation of a three-dimensional spongy-reticulate continuous structure of the gluten frame, because it determines the elastic and elastic properties of the medium and is relevant in dispersing gas in a liquid. That is why, the objective of the research was to establish the relationship between the gas-holding capacity of the medium and the energy spent on the hydration of the components. The research solved the problem of determining the gas-holding capacity of the medium with variable parameters of the height of the liquid phase depending on the intensity of mixing, time of the transient processes of formation of the full volume of the gas-liquid medium, time of the transient process of the output of the dispersed gas phase. The difference in levels before the formation of the gas phase and in the mode of mixing (aeration) determines the value of the gas-holding capacity. In this regard, we came to the conclusion about the expediency of the complete destabilization of the established regimes due to the change in the modes of action of the working body in the flow system. At the same time, one more feature should be mentioned. Part of the gas phase that existed and continues to exist in a new regime after mixing enters the regime of the transition process. Therefore, the most effective mixing occurs in case of compliance with the shifted mode of dosing of components in a suspended state and the mechanical influence of the working body. Considering the problems and conditions for mixing the scam, the requirements for the design of the mixer are determined, and also it is established that feeding of components should last at least 45 seconds. During this period, hydration occurs and energy consumption is reduced. This approach of the formation of pulsed flows of surface contours during the interaction in a suspended state of the dosing components, under the rotating action of the disc-shaped working body and the forces of gravity, creates the conditions for intensification of transferring the mass and biochemical processes under conditions of thermodynamic equilibrium with the corresponding desorption bonds of the dissolved part of the gaseous phase and liquid, which reveals a new method of mixing and allows further use of cylindrical working chambers in structural calculations.
